<p><P>PROBLEM TO BE SOLVED: To stably carry out heating operation at low outside air temperatures by simple control. <P>SOLUTION: In the air conditioner 1, an opening of a main electric expansion valve 17 of an outdoor unit 2 is controlled by a condensation temperature control means 34, and a condensation temperature is measured by a condensation temperature detecting means 32 provided in an indoor heat exchanger 15 to carry out feedback control. A desired value of a delivery temperature is corrected by a delivery temperature correcting means 36 in response to the opening of the main electric expansion valve 17, an amount of a liquid refrigerant flowing through a bypass line 16 is controlled by a delivery temperature control means 35 in response to the corrected desired value, and control of the delivery temperature of a gas refrigerant delivered from a compressor 11 is carried out. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
