<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioner and a refrigerator that use existing piping to replace the heat-source equipment of a gas heat pump type system with that of an electric heat pump type system and that enable smooth start of a compressor by discharging liquid refrigerant in the compressor without producing an eddy current even if PAG oil with low volume resistivity is present in the compressor. <P>SOLUTION: In the air conditioner and the refrigerator, the existing piping of an air conditioner and a refrigerator that use PAG oil as refrigerator oil is reused to replace the heat-source equipment 1 of an electric heat pump type system that uses refrigerator oil other than PAG oil. The air conditioner and the refrigerator include a heating means for heating from the outside a compressor 10 built into the heat-source equipment 1, and a controller 32 that starts the compressor 10 after the compressor 10 has been heated by the heating means. The level of liquid that collects in the bottom of the compressor 10 prior to the start of the compressor 10 is kept lower than a conduit 28 inside the compressor 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
