<P>PROBLEM TO BE SOLVED: To provide an air conditioner in which the rise time of heating operation is quickened. <P>SOLUTION: The air conditioner includes: a refrigerating cycle in which a refrigerant flows through a compressor 6, a four-way valve 8, an indoor heat exchanger 16, an expansion valve 12, an outdoor heat exchanger 14, and the four-way valve 8 in this order during heating; and a heat storage tank 32 that accommodates a heat storage material 36 for storing therein heat generated by the compressor 6 and a heat storage heat exchanger 34. The air conditioner includes: a heat storage bypass circuit for connecting a refrigerant pipe between the indoor heat exchanger 16 and the expansion valve 12 and a refrigerant pipe between the four-way valve 8 and an inlet port defined in the compressor 6; a defrosting bypass circuit for connecting a refrigerant pipe between the expansion valve and the outdoor heat exchanger and a refrigerant pipe between an outlet port defined in the compressor and the four-way valve; and a heat storage two-way valve provided in the heat storage bypass circuit. The air conditioner is also provided with: a normal heating mode; and a quick heating mode whose rise time is quickened compared to the normal heating operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
