Claims

[Scope of utility model registration request]

In an air conditioner in which the heat exchanger constituting the indoor unit is divided into an upstream heat exchanger and a downstream heat exchanger to perform dehumidifying operation, the refrigerant at the inlet and outlet is placed between the two front exchangers. An air conditioner characterized by inserting a check valve that closes or throttles a refrigerant flow path when the pressure difference exceeds a predetermined value.
