Claims

[Scope of utility model registration request]

comprising a first indoor heat exchanger and a second indoor heat exchanger,
During dehumidification operation, the refrigerant exiting the first indoor heat exchanger is expanded and flows into the second indoor heat exchanger, and during cooling operation, the refrigerant exiting the first indoor heat exchanger is expanded. In an air conditioner that allows the refrigerant to flow directly into the second indoor heat exchanger, this check valve has a built-in elastic body that is displaced by a change in temperature of the refrigerant exiting the first indoor heat exchanger. The elastic body is provided between a first indoor heat exchanger and a second indoor heat exchanger, and the elastic body operates the check valve depending on the temperature of the refrigerant exiting the first indoor heat exchanger during cooling operation. An air conditioner characterized in that, although the check valve is open, the check valve is moved to close depending on the temperature of the refrigerant exiting the first indoor heat exchanger during dehumidification operation.
