    摘要： The present invention relates to a thermoelectric material containing CoSb 3 compound for converting heat to electricity, and provides a p-type thermoelectric material of CoSb 3 having a high power factor by achieving high Seebeck coefficient consistently with high electric conductivity in a material of CoSb 3 system without causing increase in heat conductivity. By sintering Co 0.07 Pt 0.03 Sb 3 alloy powder using the spark plasma sintering technique, the material is densified, while growth of grains is restricted, so that a higher electric conductivity is achieved with a heat conductivity maintained in a low level, and the figure of merit as a heat-transfer material is improved. Also, by providing such heat insulating layer as an oxide intermediately in a grain boundary of a compound of CoSb 3 in a sintered body, the heat conductivity is reduced. Further, the Seebeck coefficient is increased by adding a rare earth metal to the thermoelectric material of CoSb 3 , and allowing it to be precipitated in grain boundaries of the sintered body.

    摘要： An absorption heat pump apparatus using a refrigerant (RF) as a heat exchanging medium includes a vapor generator (4) for producing a dilute refrigerant solution (RF') and a heat exchanger (100) having an evaporator (12) for producing evaporated refrigerant gas and an absorber (17) for making the evaporated refrigerant gas to be absorbed into the dilute refrigerant solution (RF'). A plurality refrigerant paths (25) extending inside the evaporator (12) and absorber (13) for flowing the refrigerant (RF) inside for heat exchange operation. Each inlet end of refrigerant paths (25) is connected to an inlet (23) before the evaporator (12) by a plurality of first capillary paths (18). Each outlet end of refrigerant paths (25) is joined to an outlet (27). A plurality of second capillary paths (18) are connected to the refrigerant paths (25) before the absorber (17) for supplying the dilute refrigerant solution (RF') to the absorber (17). When passing through the capillary paths (13 and 18), the refrigerant (RF and RF') is cooled due to the pressure loss.
