1. Thermal Storage Technology: (1) The clathrate hydrate with thermal storage density of 0.2MJ/kg at 10℃ was developed. (2) High thermal conductivity was confirmed by the compound structure body of porous metal and heat storage materials.
2. Heat Shield Technology: (3) Heat shield films which can reduce 10% of cooling load in summer (compared with that of commercial one) wad developed.
3. Heat Insulation Technology: (4) Industrial kiln having high energy efficiency was fabricated by high performance porous ceramics and other developed materials.
4. Thermoelectric Materials and Devices: (5) High-throughput screening technique for searching new thermoelectric materials was demonstrated. In PEDOT:PSS films, we achieved a power factor of 110 microW/mK2. (6) Thermoelectric performance of the skutterudite material was improved by 20% (ZT=1.2). (7) For the energy efficiency of co-generation systems, thermoelectric generation from hot water (65℃) was demonstrated. (8) The flexible thermoelectric module using organic materials was developed and its performance was examined revealing the importance of heat resistance. (9) High-performance clathrates were investigated to achieve practical thermoelectric generators. (10) Large size silicide pellets (~70x70mm2) with less than 2% deviation of in-plane properties were sintered.
5. Power Generation Technology Utilizing Waste Heat: (11) A waste heat power generation system for 1kW class was constructed and the power generation experiment using actual exhaust gas was conducted.
6. Heat Pump Technology: (12) Preliminary test of centrifugal compressor was initiated to evaluate likelihood of the target COP. (13) Candidates of refrigerant, 2-stage compression and purge cycle were selected and the main components for the heat pump system were verified. (14) A water-cooled prototype chiller which can supply 7℃ chilled water was driven by 60℃ hot water.
7. Thermal Management: (15) To develop a high efficient heat transport system for automobile, a loop-type heat pipe with 1.9kW heat transport was investigated. (16) The heat absorption/heat transfer system technologies for the motor and the inverter of electric vehicles were investigated. (17) For the compact absorption refrigerator in automobile absorbents with low crystallization temperatures was developed. (18) The heat exchanger technology of the adsorption cooling system for vehicle was investigated and cooling system performance of 1.5kW was indicated.
8. Survey Related to Heat Fundamental Technology: (19) The unused heat discharge from the exhaust gas in factories of 9 types of industry was classified and evaluated. GWP values of new candidates of refrigerant for heat pump were evaluated. The computational studies were conducted for developing new thermal materials. The thermal material database having physical properties was stored.
