Provided is a refrigeration circuit that is capable of storing excess coolant arising during a cooling operation when the capacity of an outdoor heat exchanger is less than the capacity of an indoor heat exchanger. In the refrigeration circuit (11), the indoor heat exchanger (51) is a cross-fin heat exchanger and the outdoor heat exchanger (25) is a stacked heat exchanger. Also, a coolant reservoir tank (27) is provided between the outdoor heat exchanger (25) and an expansion valve (29). The capacity of the outdoor heat exchanger (25) becomes less than the capacity of the indoor heat exchanger (51) and so excess coolant arises during the cooling operation, but in this refrigeration circuit (11), the excess coolant is stored in the coolant reservoir tank (27), and so the occurrence of obstacles to coolant control is prevented. |
