Kind Code:
A1
Abstract:
This air conditioner (100) comprises an outdoor unit (101), an indoor unit (102), and a first pipe (111) and a second pipe (112) connecting same. The outdoor unit (101) has a first heat exchanger (3), a first expansion valve (41), a compressor (1), and a switching device (2) configured to be able to switch between a cooling state and a heating state. The indoor unit (102) has a second heat exchanger (6), a second expansion valve (42), and a third heat exchanger (51). When the temperature of a first refrigerant flowing between the second expansion valve (42) and the first pipe (111) is higher than the temperature of a second refrigerant flowing between the second expansion valve (42) and the second heat exchanger (6), the third heat exchanger (51) is configured to perform heat exchange between the first refrigerant and the second refrigerant, and not to perform heat exchange between the first refrigerant and the second refrigerant when the temperature of the first refrigerant is lower than the temperature of the second refrigerant.
