<P>PROBLEM TO BE SOLVED: To achieve a non-stop heating operation without reversely rotating a refrigerating cycle during the heating operation of an air conditioner. <P>SOLUTION: An outdoor heat exchanger serving as an evaporator during heating is divided into a plurality of heat exchangers with a refrigerant divided flow path as a reference. A bypass circuit for bypassing the discharged gas so as to correspond to these exchangers from a compressor is formed, and a solenoid opening/closing valve for controlling a bypass state are installed. Since defroster operation is performed for each heat exchanger without reversely rotating the refrigerating cycle during the heating operation of the air conditioner, the non-stop heating operation can be achieved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
