A cooling electric expansion device (10) expands a refrigerant condensed by an outdoor heat exchanger when a refrigeration cycle is in a cooling state. A heating electric expansion device (20) expands the refrigerant condensed by an indoor heat exchanger when the refrigeration cycle is in a heating state. The heating electric expansion device (20) is connected in parallel to the cooling electric expansion device (10) to form flows of the refrigerant that are parallel to each other. A blocking device (50) blocks the refrigerant from flowing into the cooling electric expansion device (10) when the refrigeration cycle is in the heating state, and blocks the refrigerant from flowing into the heating electric expansion device (20) when the refrigeration cycle is in the cooling state.
