Claims

[Scope of utility model registration request]

In an air conditioner equipped with a refrigeration cycle consisting of a compressor, a condenser, an expansion mechanism, an evaporator, etc., a first expansion mechanism, an air heat exchanger, and a second expansion mechanism are provided between the condenser and the evaporator.
a first bypass circuit that sequentially connects the expansion mechanisms in series and bypasses the first expansion mechanism;
A second bypass circuit that bypasses the expansion mechanism and a heat exchanger bypass circuit that bypasses the air heat exchanger are provided, so that the air heat exchanger can be selectively used as a condenser or an evaporator. air conditioner.
