Japanese Patent JP7448848
Kind Code:
B2
Abstract:
Provided is an air conditioning device which can reduce a filled refrigerant amount. This air conditioning device (1) comprises: an indoor heat exchanger (31); an outdoor heat exchanger (40); and a four-way switching valve (22) that switches between a heating operation in which the indoor heat exchanger (31) is caused to function as a condenser for a refrigerant and the outdoor heat exchanger (40) is caused to function as an evaporator for the refrigerant, and a cooling operation in which the indoor heat exchanger (31) is caused to function as an evaporator for the refrigerant and the outdoor heat exchanger (40) is caused to function as a condenser for the refrigerant, wherein the internal volume of the indoor heat exchanger (31) is lower than the internal volume of the outdoor heat exchanger (40), and the internal volume of a region in which the refrigerant flows in the outdoor heat exchanger (40) during the cooling operation is lower than the internal volume of a region in which the refrigerant flows in the outdoor heat exchanger (40) during the heating operation.
