As a result, heat from the outside air is supplied to the heat storage material 15 in the low temperature chamber 16 using phase change. Of course, the critical temperature for phase change of the heat storage material 15 is set lower than the temperature of the outside air. During normal heating, the heat medium in the second tank (medium temperature tank) 7 is transferred to the three-way valve 2.
The water is circulated through the heater 5 by the pump 3.

It is circulated through the air conditioner 6. The heated heat medium from the air conditioner 6 is cooled by the evaporator 14 in the low temperature tank 16 and guided to the air conditioner 6 again. At this time, if the capacity of the evaporator 14 is determined in accordance with the cooling load, the phase of the heat storage material 15 in the low temperature chamber 16 will not change. During this cooling operation, the heat medium in the intermediate temperature tank 7 is heated more than necessary by the condenser 9, the condensation temperature increases, and the operating efficiency of the refrigeration circuit 19 deteriorates.
