摘要： PROBLEM TO BE SOLVED: To substantially completely eliminate occurrence of a supercooling phenomenon even when an antifreezing apparatus on an indoor machine side is not operated by temporarily interrupting cooling operation by switching off an auxiliary power relay inserted into a power supply circuit of a compressor in an outdoor machine when refrigerant temperature is lower than set temperature. SOLUTION: When a refrigerant coil becomes a supercooled state during cooling operation, water is filled in a heating heat source machine, a warm water coil, and a warm water flow pipe and a warm water return pipe, so that there is a fear that water in the warm water coil is frozen. Therefore, when temperature detected by any of a refrigerant coil temperature detection sensor 11a and a warm water coil temperature detection sensor 12a becomes a set value or lower, an antifreezing apparatus is driven to instantaneously interrupt the operation of a compressor 14a in an outdoor machine 13. An auxiliary power relay 21 is provided in a power supply circuit 4 in series with a power relay 5, and when a refrigerant temperature detection sensors 13a, 13b detect temperature of the set value or lower, the auxiliary relay 21 is switched off with a complement safety circuit 20.
