In this case, three-way valve 8, two-way valve 6, 10, 13, four-way switching valve 1
6. By installing the check valves 7, 9, 12, and 14, the refrigerant flows only to the heat exchange necessary for each operation mode, and does not flow to other unnecessary heat exchangers. Therefore, the capacity can be improved by reducing the resistance of the refrigerant. As a result, the pressure of the refrigerant is stabilized, and at the same time, the refrigerant flow is unidirectional to the air heat exchanger 4, so that winter frost formation is reduced and the defrosting operation during frost formation can be completed in a short time. In addition, since the refrigerant flow in one of the other heat exchangers 2 and 3 is unidirectional, the heat exchange between the hot and cold water and the refrigerant gas is the counter flow method, so that the heat exchange capacity can be improved. In addition, various advantages such as satisfying all the above objects of the present invention can be obtained.
