When the exhaust fan 3 is turned off, the heat pump circulation system stops. When the temperature in the distribution insulation water tank 9 reaches the set temperature, the condenser 7 inside the distribution insulation water tank 9 is controlled to stop by the four-way expansion valve 5. When the water level inside the distribution insulation water tank 9 drops, the water inside the main heat source exchange water tank 11 is replenished to the inside of the distribution insulation water tank 9.
