To provide an air conditioner in which the highly efficient performance of a heat exchanger is obtained by providing an auxiliary heat exchanger connected between a first expansion mechanism and a second expansion mechanism and a control means for adjusting the opening degree of the valves of the first and second expansion mechanisms.
A compressor 10, an indoor heat exchanger 20, a first expansion mechanism 60, a second expansion mechanism 61 and an outdoor heat exchanger 40 are sequentially together in an annular shape by a piping to form a refrigerating cycle for circulating a refrigerant. An auxiliary heat exchanger 41 is connected between the first expansion mechanism 60 and the second expansion mechanism 61, and a control means adjusts the valve opening degree of the first expansion mechanism 60 and the second expansion mechanism 61. Thus, the auxiliary heat exchanger 41 as well as the outdoor heat exchanger 40 or the indoor heat exchanger 20 can serve as a condenser, so that the performance of the condenser can be improved.
