    Renzhuo WANG, Makoto NOHTOMI

    Journal of Life Cycle Assessment, Japan   17 ( 2 ) 110 - 123  2021.04  [Refereed]

     View Summary

    In this study, in order to achieve the greenhouse gas emission reduction target of the Paris Agreement, an education program on global warming prevention for citizens was developed and conducted. The participants were people aged 60-80 who live in Honjo city, Saitama Prefecture. The program content design was based on the pro-environmental behavior model and divided into four consecutive sections. First two sections were about global warming, and the last two were about the methods and effects of countermeasures against global warming such as energy saving in daily life. In order to confirm the effect of the education program, the participants' awareness changes were investigated before and after each section, and the energy saving behavior changes were investigated in the third and fourth section.

    Regarding the results, the participants' crisis awareness and interest in global warming showed significant increase and they had strong correlation. Furthermore, after the information about specific methods of energy savings were provided, most of the participants showed positive changes in their energy saving behavior as well. With these results, the positive effect of this program was proved.

  • Design, Construction and Evaluation of a Standing Wave Thermoacoustic Prime Mover

    Ikhsan Setiawan, Prastowo Murti, Wahyu N. Achmadin, Agung B. S. Utomo, Makoto Nohtomi

    PROCEEDINGS OF THE 4TH INTERNATIONAL CONFERENCE AND EXHIBITION OF SUSTAINABLE ENERGY AND ADVANCED MATERIALS 2015 (ICE-SEAM 2015)   1717  2016  [Refereed]

     View Summary

    A standing wave thermoacoustic prime mover (TAPM) has been succesfully designed, constructed, and evaluated. It consists of a resonator with length of 128 cm, a stainless-steel wire-mesh stack with 14 mesh number, two heat exchangers, and air at atmospheric pressure as the working gas inside the resonator. The stack is placed inside the resonator near one of its closed-ends and has 4 cm length. The hot and ambient heat-exchangers are attached at each end of the stack to provide a large temperature gradient along the stack which is required for generating acoustic energy. An electric heater with maximum power of 400 W is used to supply thermal energy to the TAPM. The temperatures and dynamic pressures are measured by using type-K thermocouples and pressure transducers, respectively. We evaluated the prime mover by experimentally investigating the influence of heat input power on the onset temperature difference, time to reach the onset condition, sound frequency, and sound pressure amplitude. It was found that input power below 255 W could not generate sound, and its increase from 255 W to 400 W did not significantly change the onset temperature difference and sound frequency, namely of around 258 degrees C and 141 Hz (at temperature difference Delta T across the stack of 300 degrees C), respectively. In addition, the increase of input power in the range of 225 W - 400 W has raised the pressure amplitude from 3.3 kPa up to 4.5 kPa (within Delta T of 300 degrees C - 320 degrees C). Moreover, we found that the time to reach onset condition was inversely proportional to the input power. We also checked the influence of temperature difference across the stack on the sound frequency and sound pressure amplitude. It was observed that the frequency was slightly increasing from 139 Hz to 142 Hz and pressure amplitude was getting higher from 1.4 kPa to 5.1 kPa when the temperature difference was rising from 280 degrees C to 350 degrees C, with input power of 353 W.

  • Experimental Study on a Standing Wave Thermoacoustic Prime Mover with Air Working Gas at Various Pressures

    Ikhsan Setiawan, Wahyu N. Achmadin, Prastowo Murti, Makoto Nohtomi

    4TH INTERNATIONAL CONFERENCE ON SCIENCE & ENGINEERING IN MATHEMATICS, CHEMISTRY AND PHYSICS 2016 (SCIETECH 2016)   710  2016  [Refereed]

     View Summary

    Thermoacoustic prime mover is an energy conversion device which converts thermal energy into acoustic work (sound wave). The advantages of this machine are that it can work with air as the working gas and does not produce any exhaust gases, so that it is environmentally friendly. This paper describes an experimental study on a standing wave thermoacoustic prime mover with air as the working gas at various pressures from 0.05 MPa to 0.6 MPa. We found that 0.2 MPa is the optimum pressure which gives the lowest onset temperature difference of 355 degrees C. This pressure value would be more preferable in harnessing low grade heat sources to power the thermoacoustic prime mover. In addition, we find that the lowest onset temperature difference is obtained when tau(h)/delta(k) ratio is 2.85, where tau(h) is the hydraulic radius of the stack and delta(k) is the thermal penetration depth of the gas. Moreover, the pressure amplitude of the sound wave is significantly getting larger from 2.0 kPa to 9.0 kPa as the charged pressure increases from 0.05 MPa up to 0.6 MPa.

    Wahyu Nur Achmadin, Ikhsan Setiawan, Agung Bambang Setio Utomo, Makoto Nohtomi

    ADVANCES OF SCIENCE AND TECHNOLOGY FOR SOCIETY   1755  2016  [Refereed]

     View Summary

    A research on the influence of resonator length on the performance of a standing wave thermoacoustic prime mover has been conducted. The thermoacoustic prime mover consists of an electric heater, a resonator tube filled with atmospheric air, and a stack. The stack was made of stainless steel wire mesh screens with mesh number of # 14. The stack had a length of 5 cm and placed 13 cm from resonator hot-end. The resonator tube was made of stainless steel pipe with 6.8 cm inner diameter. The electric heater which has a maximum power capability of 299 W was attached to the hot side of the stack. We varied the resonator length from 105 cm until 205 cm. It was found that the thermoacoustic prime mover with a resonator length of 155 cm generated the sound with the smallest onset temperature difference and shortest time to reach the onset condition, those are 252 degrees C and 401 s, respectively. Also, the prime mover with a resonator length of 105 cm produced the highest frequency that is 174 Hz. On the other hand, by using resonator length of 180 cm, the prime mover generated the highest pressure amplitude of 0.0041 MPa, and the thermoacoustic device delivered the highest acoustic power of 2.8 W and efficiency of 0.9%.

  • Critical Temperature Differences of a Standing Wave Thermoacoustic Prime Mover with Various Helium-Based Binary Mixture Working Gases

    Ikhsan Setiawan, Makoto Nohtomi, Masafumi Katsuta

    3RD INTERNATIONAL CONFERENCE ON SCIENCE & ENGINEERING IN MATHEMATICS, CHEMISTRY AND PHYSICS 2015 (SCITECH 2015)   622 ( 1 )  2015  [Refereed]

     View Summary

    Thermoacoustic prime movers are energy conversion devices which convert thermal energy into acoustic work. The devices are environmentally friendly because they do not produce any exhaust gases. In addition, they can utilize clean energy such as solar-thermal energy or waste heat from internal combustion engines as the heat sources. The output mechanical work of thermoacoustic prime movers are usually used to drive a thermoacoustic refrigerator or to generate electricity.
    A thermoacoustic prime mover with low critical temperature difference is desired when we intend to utilize low quality of heat sources such as waste heat and sun light. The critical temperature difference can be significantly influenced by the kinds of working gases inside the resonator and stack's channels of the device. Generally, helium gas is preferred as the working gas due to its high sound speed which together with high mean pressure will yield high acoustic power per unit volume of the device. Moreover, adding a small amount of a heavy gas to helium gas may improve the efficiency of thermoacoustic devices.
    This paper presents numerical study and estimation of the critical temperature differences of a standing wave thermoacoustic prime mover with various helium-based binary-mixture working gases. It is found that mixing helium (He) gas with other common gases, namely argon (Ar), nitrogen (N-2), oxygen (O-2), and carbon dioxide (CO2), at appropriate pressures and molar compositions, reduce the critical temperature differences to lower than those of the individual components of the gas mixtures. In addition, the optimum mole fractions of He gas which give the minimum critical temperature differences are shifted to larger values as the pressure increases, and tends to be constant at around 0.7 when the pressure increases more than 2 MPa. However, the minimum critical temperature differences slightly increase as the pressure increases to higher than 1.5 MPa. Furthermore, we found that the lowest critical temperature difference for He-Ar mixture gas is around 66 degrees C which is achieved in pressure range of 1.5 MPa - 2.0 MPa and mole fractions of helium of 0.55 - 0.65. The He-N-2 and He-O-2 mixture gases demonstrate almost the same performances, both have the lowest critical temperature difference around 59 degrees C at pressures of 1.0 MPa - 1.5 MPa and helium's mole fractions of 0.35 - 0.55. For all tested gases, the lowest critical temperature difference of around 51 degrees C is provided by He-C(O)2 mixture gas at pressures of 0.5 MPa - 1.0 MPa with helium's mole fractions of 0.15 - 0.40.

     View Summary

    Thailand, with its abundant agricultural resources, is a well positioned to deploy biofuels such as ethanol and biodiesel. To enhance the self-dependence on the energy and economy in rural areas, the government has implemented the "Alternative Energy Development Plan: AEDP 2012-2021", aiming to increase the amount of alternative and renewable energy utilization. To ensure the sustainability of the biodiesel production not only research on high efficient production technology improvement is need, but also studies on the impacts from promoting the non-food feedstock such as Jatropha. This study aims to evaluate environmental and social impacts of Jatropha-based biodiesel production by using the Life Cycle Assessment (LCA) concept. The scope of this study is defined as "cradle-to-gate" which includesJatropha cultivation, harvesting, oil extraction and biodiesel production. Inventory data used in this study was developed byan on-site interview and consultation with Jatropha farmers and experts throughout the three provinces in the northern part of Thailand. The environmental impacts were analyzed by the modified LCA methodology called Environmental Load Point (ELP), formulated by the Nagata Laboratory of Waseda University. The weighting factor used in ELP developed by taking Thailand as a case study. The assessment of social impacts of Jatropha biodiesel systems referred to criteria indicated in the Global Bioenergy Partnership Sustainability Indicator for Bioenergy. The results show the environmental impacts of the Jatropha biodiesel production from a localized environmental viewpoint. The social impacts are focused on results of the change in income and job creation in the local community due to the establishment of biodiesel production system. These can be useful for the policy maker to promote the advantages of non-food biodiesel and enhance the cultivation areas and production plant to the rural in further.

    2013 INTERNATIONAL CONFERENCE ON SCIENCE & ENGINEERING IN MATHEMATICS, CHEMISTRY AND PHYSICS (SCIETECH 2013)   423 ( 1 ) 2035  2013  [Refereed]

     View Summary

    Thermoacoustic refrigerators are cooling devices which are environmentally friendly because they don't use hazardous gases like chlorofuorocarbons (CFCs) or hydrofuorocarbons (HFCs) but rather air or inert gases as working medium. They apply sound wave with high intensity to pump heat from the cold to hot the regions through a stack in a resonator tube. One of the important parameters of thermoacoustic refrigerators is the porosity (blockage ratio) of stack which is a fraction of cross sectional area of the resonator unblocked for the gas movement by the stack. This paper describes an experimental study on how the porosity of parallel plate stack affects the temperature decrease of a thermoacoustic refrigerator. The porosity of parallel plate stack is specified by the thickness of plates and the spacing between plates. We measured the maximum temperature decreases of thermacoustic refrigerator using stacks with various porosities in the range of 0.5-0.85, with plate spacing from 0.5 mm to 1.5 mm and plate thicknesses 0.3 mm, 0.4 mm, and 0.5 mm. The measurements were done with two resonators with length of 0.8 m and 1.0 m, with air at atmospheric pressure and room temperature, correspond to thermal penetration depths (delta(kappa)) of 0.26 mm and 0.29 mm, respectively. It was found that there is an optimum porosity which gives the largest temperature decreases, and there is a tendency that the optimum porosity shifts to a larger value and the temperature decrease become larger when we used a stack with thinner plates. On the other hand, the study on the dependence of the temperature decrease on the plate thickness and the plate spacing reveals more useful information than that on the stack porosity itself. We found that stack with thinner plates tends to give larger temperature decrease, and the plate spacing of around 4 delta(kappa) leads to the largest temperature decrease.

    PROCEEDINGS OF THE ASME/JSME 8TH THERMAL ENGINEERING JOINT CONFERENCE 2011, VOL 2     333 - 340  2011

     View Summary

    It has been performed a simple simulation and calculation on solar energy collection which is used indirectly to power a thermoacoustic prime mover by producing pressurized hot steam which would supply thermal energy to the prime mover via sealed-off hot heat exchangers. The solar energy collection took place in Yogyakarta City - Indonesia where the average energy of solar global radiation of 4.8 kWh/m(2)/day (17.3MJ/m(2)/day) is available around the year The calculation including the amount of the remaining heat stored, steam pressure, and steam temperature for various areas of the collector unit (Fresnel lens) and volume of water, were done as a function of time for several days. We found that appropriate combinations of lens area and water volume would enable us to operate the thermoacoustic prime mover continuously all day and night.

  • 波動冷凍法を用いたパルス管冷凍機・熱音響冷凍機の最適設計手法に関する研究

     View Summary

    ◎パルス管冷凍機パルス管冷凍機の設計手法に関する検討を行った.特に,パルス管冷凍機の形状寸法が冷凍機性能に与える影響を調査した従来の結果を援用すると共に,シミュレーション計算による結果を設計手法の中に有機的に取り入れることによって,簡易的な設計手法を構築した.特に,パルス管部分と運転条件との最適状態を決定するために導入れた,"Volume Ratio"はパルス管容積に対するオリフィスバルブを1サイクルに通過する動作流体の総体積の比であり,これが0.5という状態がその形状条件における最低到達温度を記録することを把握した.また,諸損失(蓄冷器部分の実験的情報を含む)を考慮に入れたシミュレーション計算によって,得られる低温度と冷凍負荷との関係を概ね把握することが可能となった.◎熱音響冷凍機および熱駆動発振器熱音響冷凍機と熱駆動発振器を組み合わせることによって,完全に機械的可動部分が存在しない冷凍システムの構築を実現した.特に冷凍能力や効率の面で特筆すべきものではないが,138Wの電気入力に対して14Wの冷凍能力を室温状態で得ることに成功し,総合効率が10.18%を記録した.ここでは,機械的可動部分が存在しない特徴から,特に長期にわたるメンテナンスが難しい状況での冷凍システムの構築が可能であることが実証された.◎性能評価に関してパルス管冷凍機のような極低温冷凍機や構造が簡単な熱音響冷凍機は,従来のエネルギ輸送効率の観点での成績係数だけでは評価できないメリットを持っていることが指摘されている.特に,パルス管冷凍機では得られる温度領域の広さと温度到達の早さには特筆すべき点があり,また熱音響冷凍機では構造の簡易性が性能評価において有利となる面を持っている.今後も,さらに多くの観点から冷凍機システムの性能評価を行い,ケーススタディによる適用領域の模索を続ける必要がある

     View Summary

    Thailand, with its abundant agricultural resources, is a well positioned to deploy biofuels such as ethanol and biodiesel. To enhance the self-dependence on the energy and economy in rural areas, the government has implemented the "Alternative Energy Development Plan: AEDP 2012-2021", aiming to increase the amount of alternative and renewable energy utilization. To ensure the sustainability of the biodiesel production not only research on high efficient production technology improvement is need, but also studies on the impacts from promoting the non-food feedstock such as Jatropha. This study aims to evaluate environmental and social impacts of Jatropha-based biodiesel production by using the Life Cycle Assessment (LCA) concept. The scope of this study is defined as "cradle-to-gate" which includesJatropha cultivation, harvesting, oil extraction and biodiesel production. Inventory data used in this study was developed byan on-site interview and consultation with Jatropha farmers and experts throughout the three provinces in the northern part of Thailand. The environmental impacts were analyzed by the modified LCA methodology called Environmental Load Point (ELP), formulated by the Nagata Laboratory of Waseda University. The weighting factor used in ELP developed by taking Thailand as a case study. The assessment of social impacts of Jatropha biodiesel systems referred to criteria indicated in the Global Bioenergy Partnership Sustainability Indicator for Bioenergy. The results show the environmental impacts of the Jatropha biodiesel production from a localized environmental viewpoint. The social impacts are focused on results of the change in income and job creation in the local community due to the establishment of biodiesel production system. These can be useful for the policy maker to promote the advantages of non-food biodiesel and enhance the cultivation areas and production plant to the rural in further.

     View Summary

    A looped tube type thermoacoustic prime mover with multiple regenerators driven by pressurized steam is being constructed. The pressurized steam is produced within a container filled by water which is boiled by an immersion electric heater. The steam is then let to flow t the hot heat exchangers of the thermoacoustic prime mover. The maximum pressure and temperature of the steam can be increased by adding extra water into the container when most of initial amount of water has changed to steam. The thermoacoustic prime mover with one to four regenerators will be tested. After laboratory test, we plan to realize a thermoacoustic prime mover driven by natural heat, by replacing the immersion electric heater with concentrated sunlight, and by utilizing steam from geothermal well.

     View Summary

    Because energy consumption by demand for electricity, air-conditioning and hot water supply is so large in the small-scale stores such as a restaurant, a fast food and a convenience store, it is very effective in saving energy and environmental preservation to introduce a power generation and heat supply system. In this paper, examination in effect of introducing the system is conducted in these small-scale stores. The system consists of a Stirling engine generator, a combustor, an exhaust gas heat exchanger or air pre-heater, and a low temperature regenerative desiccant air-conditioner. It has a system efficiency of 102% at cooling and 115% at heating. From the results of examination, it makes clear that saving energy and reduction in CO_2 emissions are achieved in restaurants, but the system introduction hardly has an effect in convenience stores.

    PROCEEDINGS OF THE ASME/JSME 8TH THERMAL ENGINEERING JOINT CONFERENCE 2011, VOL 2     333 - 340  2011  [Refereed]

     View Summary

    It has been performed a simple simulation and calculation on solar energy collection which is used indirectly to power a thermoacoustic prime mover by producing pressurized hot steam which would supply thermal energy to the prime mover via sealed-off hot heat exchangers. The solar energy collection took place in Yogyakarta City - Indonesia where the average energy of solar global radiation of 4.8 kWh/m(2)/day (17.3MJ/m(2)/day) is available around the year The calculation including the amount of the remaining heat stored, steam pressure, and steam temperature for various areas of the collector unit (Fresnel lens) and volume of water, were done as a function of time for several days. We found that appropriate combinations of lens area and water volume would enable us to operate the thermoacoustic prime mover continuously all day and night.

    Because not only electricity consumption per unit area but also hot water supply demand is large in the small-scale stores such as a restaurant, a fast food and a convenience store, it is very effective in saving energy and environmental preservation to introduce a power generation and heat supply system. In this paper, present conditions of energy consumption and electricity/heat demand in these small-scale stores are investigated, and the new system using a Stirling engine is suggested, which can supply electricity, hot water and air-conditioning output. The system consists of a Stirling engine generator, a combustor, an exhaust gas heat exchanger or air pre-heater, and a low temeperature regenerative desiccant air-conditioner. It is expected an efficiency of 80% or more at cooling and 90% or more at heating.

    The Proceedings of the Symposium on Stirlling Cycle   2009.12   121 - 124  2009

     View Summary

    Test models of free piston Stirling engine (FPSE) converter have been developed as heat-to-electricity power converters for a demonstration of solar heat energy utilization at the Japan Aerospace Exploration Agency (JAXA), for future aerospace applications. In the case of the FPSE, the output power of the working gas is directly used as the linear alternator input and then converted into electrical power. Therefore, the linear alternator is one of the most important devices in the FPSE. On the other hand, thermo-acoustic engine (TAE) is a technology that uses high-amplitude sound waves induced by a temperature difference. The work of the sound waves can be converted to electricity by a highly efficient linear alternator. Therefore, the linear alternator is also a key component for the TEA. To realize efficient linear alternators that are suitable for the TAE, several types of linear alternators have been designed and developed based on JAXA's FPSE technology. In this study, the performance evaluations of the linear alternators were conducted.

    Consideration of 3 R (Reduce, Reuse, Recycle) is strongly required for industrial products' design. General-purpose pumps' design makes them difficult to disassemble and classify into single material. Their value-adding functions continue to improve through increased quality, reduced costs, unification of multiple functions, adoption of bond connection methods, built-in compression, and so on. Such features make disassembly difficult.<BR>We developed and manufactured an environmentally friendly general-purpose pump to improve the problems cited above. We specifically improved the disassembly property of the motor, which includes useful, resource-rich parts, and introduction of the concept of“Up-Grading”products, which can realize up-grading of its structure during the use stage. Our assessment method shows that this pump has a 36% lower environmental load than the former product.

     View Summary

    Owing to utilization of highly advanced earth-observation sensors and superconducting devices on communication satellites, space-borne cryocoolers have been increasingly used in many space missions for recent years. Therefore, it is necessary to carry out fundamental researches for development of space-borne cryocoolers with compact-lightweight, high performance, high reliability, and long service life. New cooling systems of thermoacoustic devices have gotten a lot of attention recently. We suggest a thermoacoustic engine as a pressure wave source for a pulse tube refrigerator, which is expectedly used for thermally-driven cooling system in orbit without electricity. Although the existing thermal compressor needs a long resonance tube, the proposed cooling system is equipped with solid displacers instead of bulky and massive tube. In this study, thermoacoustic prime mover of solid-displacer type is experimentally investigated.

It can be said that effective maintenance and the operation of the energy consumption type product, such as business equipment, are extremely effective, for instance as CO_2 measures. So, as a familiar example, we have researched about the effectiveness of the operating information management system intended for the vending machine, since its diffusion of the whole country is very high. Concretely, we have examined the operational condition of the cup type and the can vending machine set up in the Waseda University Ohkubo campus, and its energy-saving measures too. Driving matched from acquired data to the number of buyers of every time zone that the vending machine was able to be used, therefore power consumption during a day confirmed 17% or less had been reduced in the cup type vending machine, by 3% or less in the can vending machine.

    In these years, as the correspondence of the global environmental problems like global warming, exhaustion of energy and so on, the construction of the environmental-friendly society is strongly required. For constructing such society, as concerns the industrial products not only the consideration to 3R (Reduce, Reuse, Recycle) at the design stage, but also the management, by the maker itself, of the energy saving at the using stage and proper treatment for the used products at the recycle and waste stage is demanded under the principle of Extended Producer Responsibility (EPR). However, such a system that manages all the life cycle of the industrial products is not investigated enough. In this study, we attempted to construct such a synthetic environmental-friendly technology for production and operation of industrial machines, especially pump system, by using special 1C tag. We call this system, Environmental Information System. At the same time we developed the special 1C tag, which exchanged information between each life cycle stage, we investigate some other technologies for decreasing the environmental impact in each process. Then, in this report, we show the findings of the investigation about a field test and the operation information collecting with the special 1C tag that actually develops. As a result, it is clarified that operation information with Special 1C tag can be collected correctly, and the driving point of the targeted machine can be guessed from obtained information

HI is Materials and Energy for taking hazardous substances into harmless as Potential, but the process for taking hazardous substances into harmless is not decided. So in this research HI is alternated by two methods (Method 1: alternate by the intensity for virgin resources. Method 2: alternate by the ratio of hazardous factor to the standard substance). Then we show the products' assessment result by using alternated HI, and compares it with other LCA. As a result, validity as the potential evaluation of E2-PA is shown.

  • Study on Air Purification system for Roadside Atmosphere using Water Adsorption : Experiment for Improvement of System Efficiency

    NAGATA Katuya, NOHTOMI Makoto, MIZUSAKI Hiroyuki, NIIMI Hiroshi, OHASI Yoshinori

    The Proceedings of the Symposium on Environmental Engineering   2003.13   239 - 242  2003

     View Summary

    Recently, the situation of air pollution centering on an urban area aggravates at the crossing of the trunk road. This paper describes purification system for NO_x and SPM using water adsorption by the bubble column. The system considers that such a local pollution area is a fixed generation source. In this experimental, it is experimented on supersonic wave for minuteness of air bubbles, oxidization of NO on low concentration by Activated Carbon Fiber (ACF) and diffusing cylinder for cutbacks of energy. As a result, supersonic wave aim at the increase in gas-liquid contact area by minuteness of air bubbles fine. Supersonic wave for minuteness is uncertain and used large energy, so the improvement in system efficiency is not expectable. Catalytic oxidation of NO to NO_2 on ACF is not identified, but the effect as adsorbent is done. We recognize that use of the diffusing cylinder improve the system efficiency. But compared with other methods, it is low, and there will be room of research from now on.

     View Summary

    Recently, a lot of environmental problems have been escalating. In these circumstances, it is not small for our everyday lives to make an impact on the global environment. So, we have suggested the LSA (Life Style Assessment) as the evaluation method of the environmental load in one's everyday life, and have evaluated the effect of environmental load reduction by improving the behavior of lifestyle. In this report, we evaluated the environmental load in using heating appliances. As a result, the environmental load became the smallest value when using "kotatsu" (small table with an electric heater underneath and covered by a quilt). Additionally, we suggested the renewal-timing index of home electric appliances from the aspect of the quantity of electric power consumption.

     View Summary

    Recently, construction of the refuse disposal system corresponding to recycling society is needed. Then, it is raised as one measure that many wastes by which the present incineration processing is carried out are used effectively as energy and resources. This research quantitatively evaluates environmental load using the Life Cycle Assessment (LCA) technique focusing on high efficiency of refuse power generation and effective use technology of a residual substance. We use the Environmental Load Point (ELP) for index. The conclusion that can realize reduction of environmental load without having big influence on economy is obtained because of enhancement of power generation efficiency by enlargement of a processing scale and steam condition improvement. Moreover, the conclusion that can realize reduction of environmental load is obtained because of the effective use technology of a residual substance considers the obtained resources as product substitution.

     View Summary

    In these years, as the correspondence of the global environmental problems like global warming, exhaustion of energy and so on, the construction of the environmental-friendly society is strongly required. For constructing such society, as concerns the industrial products not only the consideration to 3R (Reduce, Reuse, Recycle) at the design stage, but also the management, by the maker itself, of the energy saving at the using stage and proper treatment for the used products at the recycle and waste stage is demanded under the principle of Extended Producer Responsibility (EPR). However, such a system that manages all the life cycle of the industrial products is not investigated enough. In this study, we attempted to construct such a synthetic environmental-friendly technology for production and operation of industrial machines, especially pump system, by using special IC tag. We call this system, Environmental Information System. In parallel with the development of the special IC tag, which exchanges information between each life cycle stage, we investigate some other technologies for decreasing the environmental impact in each process. Then, in this report, we show the effectiveness of this system in terms of environmental impact by applying Eco-Efficiency Potential Assessment (E2-PA), which is the environmental load assessment technique we develop.

     View Summary

    The range of the assessment by E2-PA includes not only the environmental impact of the industrial products but also the utility of that. In this study, we investigate the utility of PC, laundry machine and television. For investigating those utilities it is necessary to make a multiple regression analysis based on two assumptions. One is to consider the market price of the industrial products as the objective variable and the other is to consider the factor of that as the interpretative variable. According to the result of the multiple regression analysis it is judged whether the utility is appropriate or not. And the result of the assessment by E2-PA that demanded from the multiple regression analysis is compared with the result regarding the main function as the utility about PC and laundry machine. Those consequences represent the indicator for deciding the utility of the industrial products.

As the correspondence, the construction of circulation type society is required. For constructing such society, the consideration to 3R (Reduce, Reuse, Recycle) at the design and manufacture stage of the industrial product become very important. As the correspondence to Reuse and Recycle, the improvement of disassembling property of the products is especially required. Therefore, we propose the index that we assess at disassembling property of the products quantitatively. This index is that we roughly estimate the real disassembling time from the information on the design stage, as the disassembling time becomes the guideline that we assess at disassembling property. In this study, we aim at establishing the method of the determination of the index to apply the Design for Disassembly Assessment Index to various products

    In these days, against the background of global environment problems including deletion of ozone depletion, it tends to multiuse the refrigerator along with the upgrade of the earth observation sensor and the use of the superconducting devices such as communications equipment. Therefore, it is necessary to establish a basic technology of the refrigerator development of long-lived, small, high performance, and high trust. As a cooling system that answers such a request, the pulse tube cooler and the thermoacoustic prime mover that can be ordinarily driven in a simple structure attract attention. In general, to use the resonance phenomena of the working fluid, the thermoacoustic prime mover needs a long resonance tube. Therefore, the method to use the solid displacer instead of the resonance tube was proposed. This paper reports on the test result when the stack mesh size is took as an experimental parameter by using the solid displacer and performance was examined.

    Because of employment of highly advanced earth observation sensors and employment of superconducting devices for communication equipment, number of missions with multi-cryocoolers tends to increase. Therefore, it is necessary to establish fundamental researches for space cryocooler development of small lightweight, high performance, high reliance, and a long-life. As the cooling system which responds to such a background, thermoacoustic devices attract attention. The attempt that uses a thermoacoustic engine for the pressure wave source of a pulse tube refrigerator is suggested, and if realized, application in space field is expected. In general, thermal compressors need a long resonance tube. Therefore, the system which operates solid displacer as resonator instead of a resonance tube was proposed. Though a great miniaturization of the device was achieved by adopting displacers, power loss in a displacer part became large, and a result which causes decline in efficiency was brought. Then, in this paper, the influence of displacer piston weight was investigated using three kinds pf displacers.

    The Proceedings of the Symposium on Environmental Engineering   2002.12   217 - 220  2002

     View Summary

    Gasification melting system is necessary for recycling and volume reduction of solid waste. however, many explosions accidents are caused by combustible gases filled in shredding or gasification melting process from gas cylinder and spray-can mixed within bulky waste. In this experiment, inhibition of ignition of mixed fuel composed of C_3H_8,CO and H_2,N_2 or CO_2 as the inert gas is analyzed using a spark plug as the source of ignition. As a result, 1) in waste grinder a lot of attention is needed for DME, because the ignition area of DME is larger than that of C_3H_8 and CH_4,2) according to the ignition limit calculated by Le Chatelier's formula, the security is ascertained at Pyrolysis Furnace, 3) the ignition limit is valued by the pace of increase of temperature and the product of organic radical and O containning radical.

    Recently, a lot of environmental problems became obvious. Especially, waste problem is very serious. In this condition, some events adopting "Environment" as its slogan have come to be held. In those events, however, the situation of waste generation and the data of waste treatment have not been developed yet. So, we took "Kitakyushu Expo 2001" for instance and evaluated waste treatment system with LCA method. Then, we use the Environmental Load Point (ELP) for index. As a result, we found 1) ELP for recycling is far less than that for not recycling on the kind we could calculate ELP. so it is confirmed that recycling is environmental friendly, 2) "the Zero Emission System" in this event reduced the environmental load in treating each kind of waste.

     View Summary

    In these years, increase of wastes and exhaust of resource become major issues according to the progress of mass productive, mass consumptive and mass waste economic system. As the correspondence, the construction of the sustainable society is strongly required. For constructing such society, the consideration to 3R (Reduce, Reuse, Recycle) at the design stage of industrial products become very important. Especially, as concerns Reuse and Recycle, the improvement of disassembling property of the products is one of the most important things to be considered. In this study, we attempted to investigate Disassembly-Oriented Design (DOD) for welfare tools, of which demand is estimated to increase due to the arrival of the aging society, by disassembling them. The products that we disassembled were nursing care bed and wheelchair. By disassembling them we understood the problems of the structure and compared the disassembling property of these products by applying the method of estimating products' disassembling property. Then we got the guide about DOD for these products.

    The recycling method of a plastic is evaluated as the applied usage of environmental utility potential evaluation technique E2-PA. The three kinds of the recycling methods are energy recovery, material recycling, and oil-izing and those are compared. Supposing that a plastic for recycling is the mixture of PE and PVC, The renewable-resource intensity by each recycling method is computed and measured. As mentioned above, material recycling is advantageous when accuracy sufficient by machine sorting is acquired. However, considering the user-friendliness and the case where manual sorting is required, the profitableness of energy recovery or oil-izing is also fully considered.

    A thermoacoustic refrigerator and a thermoacoustic prime mover, because of its simple structure, would serve as very desirable systems, because thermoacoustic prime movers can be driven with waste heat, such as exhaust gas from engines, or with the heat from natures such as sunlight and geothermal heat. The combined thermoacoustic refrigerator and prime mover system would become a perfect cooling system without moving parts, CFCs, and HFCs. Thus this "Thermoacoustic-driven Thermoacoustic Refrigerator" will be a candidate for the next-generation refrigeration systems. In this paper, we set up our thermoacoustic prime mover to investigate the fundamental characteristics. On the prime mover tests, the fundamental characteristics of stack dimensions are mainly checked and the condition of the oscillation generation is observed with the instantaneous measurement of temperature and pressure oscillation. The way to improve the thermal efficiency of the prime mover is mentioned in terms of the operating condition.

     View Summary

    A thermoacoustic refrigerator is remarkable because it uses natural gas as a refrigerant and doesn't need a routine maintenance. Some experimental discussions and analysis have bee done, but there are few effective methods of system design of this refrigerator. In this paper, some results of performance tests of the heat-driven thermoacoustic driver and the heat-driven thermoacoustic refrigerator are discussed. In the acoustic driver's test, some kinds of stack are used to find out the optimum condition of stack configuration. From the result, there is an optimum condition of the stack configuration such as the ratio of the hydraulic diameter (D_h) to the thermal penetration depth (δ_K), and heat exchanging area. In conclusion, a large mesh is desirable for the stack, however, since certain amount of heat transfer area is necessary for the stack so the length of stack gets longer as a necessity. In order to enhance the performance, this driver's equipment should be big. In addition, the discussion of enhancement of the system performance and the possibility as an application is done.

     View Summary

    Since environmental problems are getting to be very serious in these days, we have to provide for the protection of the environment as soon as possible. As a result of the Montreal Protocol and the Kyoto Protocol, utilization of CFCs and HFCs are restricted to phase out and to cut down respectively. Therefore, an interest is growing to apply a cryocooler to the non CFCs' and non HFCs' refrigeration system, which will be a candidate for alternatives of the traditional vapor compression refrigeration system. In particular, a helium gas is one of the promising refrigerants for its zero ODP (Ozone Depletion Potential) and zero GWP (Global Warming Potential) characteristics. In this paper, some kinds of heat exchanger have been discussed to compare the characteristics among various kinds of refrigeration system. And in addition, a Stirling cycle refrigeration system, such as pulse tube refrigeration, is focused to concretize the value of it and at the same time a checking up the feature of a pulse tube refrigerator is done. To make further reference to the performance of pulse tube refrigeration, a numerical calculation has been done. As a result of it, a velocity distribution in section varies greatly owing to the operating condition. Especially, near the solid wall, the definition of the thickness of boundary layer is difficult and that thickness acts on the refrigeration performance. Finally to improve or develop the Stirling cycle refrigeration system, some comments are made.

In the investigation on the influence of stack type on the performance, a stack of parallel plate type is the highly efficient stack. From the result, some requirements exist for the stack configuration and some of them are listed. In conclusion, the cross-sectional shape of stack is needed to be the assembly of cells which have almost the same gap between solid walls, and the operating condition has a influential factor as well as the stack configuration does so.

    ◎パルス管冷凍機:パルス管冷凍機の形状寸法が、冷凍機性能に与える影響を調査する実験を主として行った。パルス管形状寸法(長さ、内径、容積)、蓄冷器形状寸法(長さ、内径、容積)、冷媒封入圧力、稼働周波数、リザーバ容積、オリフィス開度をパラメータとして性能試験を行った結果、以下のような傾向が確認された・・稼働周波数、冷媒封入圧力、パルス管容積、オリフィス開度、リザーバ容積で決定される最適な運転条件が存在する。・蓄冷器形状寸法は、それだけを単独で変更しても上述の最適運転条件には影響を与えない。・蓄冷器形状と最低到達温度との関係は、蓄冷器損失(再熱損失)と蓄冷器における圧力損失との兼ね合いで決定される。また、冷凍機をモデル化し数値シミュレーションを実施した結果、形状条件と運転条件によって規定される最適オリフィス開度の存在、パルス管形状の影響に関して実験結果との定性的な一致を確認した。◎熱音響冷凍機:熱駆動発振器の基礎特性に関する調査を行った。発振器スタックの共鳴管における位置の最適化を図るため、スタック位置を変化させて性能試験を行った。その結果は以下の通りである。・入力量に対する圧力振幅が最大となるのは、共鳴管長に対して閉止端から約1/4の位置である。・最小入力量で圧力変動が発生するのは、共鳴管長に対して閉止端から約1/2の位置である。◎今後の展望:従来から用いられている、エネルギ消費を基本としたCOPによる冷凍機性能評価を見直し、有効エネルギ的観点から極低温冷凍機の効率を評価する手法の確立に取り組んでいる。また、地球環境への影響の観点から、既存の蒸気圧縮式冷凍機も含めた冷凍機全般の評価法の構築に取り組んでいる。これは、指標TEWI(Total Equivalent Warming Impact)を基本にして、さらにいくつかの要目を考慮することによって、より現実的な評価指標へと発展させる試みである。

    波動冷凍法とは,動作流体の圧力変動によって発生する温度変動を利用した冷凍法を言う.この冷凍法は,最近のフロン系冷媒に対する様々な規制から,次世代の冷凍法の主流となると考えられているノンフロン冷凍システムの一翼を担う可能性が高く,広範囲に亘って様々な研究が行われている.波動冷凍法の特長は,構造が比較的簡単であることや低圧力での運転が可能なこと,コスト面での優位性などが挙げられている. 1998年度研究課題では,システム内に機械的可動部が存在しない冷凍システムである,熱駆動型熱音響冷凍機の研究を中心に行い,特に設計手法が経験に依存していた点に注目し,最適設計手法の確立を目的として研究を遂行した.既にそれまでの研究で,冷凍発生部である冷凍機と圧力波発振源である発振器についてそれぞれ単体での性能試験は行われ,最適形状設計に関するある程度の指針が得られていることから,1998年度は熱音響冷凍機と熱駆動発振器を組み合わせた熱駆動型熱音響冷凍システムについての検討を行った.このシステムは装置内に機械的可動部が無いことから,信頼性が高く,長寿命・低振動であるという特長を持っている.将来的な応用として,たとえば保守が不要な状況下での冷却システムや駆動源が熱であることから諸排熱を有効に利用するシステムの一部,また自然エネルギーである地熱や太陽光エネルギーの利用も考えられている. 冷凍機・発振器がそれぞれ最大熱輸送量・最大出力を発生する条件は,装置本体の形状に大きく依存することから,冷凍機と発振器に関して,構成要素の幾何形状をパラメータとして変化させて性能への影響を評価した.その結果,最高性能を発揮する条件では,中間蓄熱媒体であるスタックの伝熱面積と音響共鳴管体積との間に一意性が存在することを確かめた.今後の課題は,未解明な部分が多い熱輸送メカニズムを明確化することと,その理論的な検証である.
