を可能にする。In this refrigerant cycle, water is discharged from a water-refrigerant condenser 11 to produce hot water using specific heat, and an air-refrigerant condenser 12 produces hot air. In this case, by using the temperature control valve 3, it is possible to operate the functions of the two condensers 11, 12 simultaneously.

）。That is, the set temperature of the temperature control valve 3 is set in advance to the air temperature.
The temperature of the hot air that is desired to be obtained by the refrigerant condenser 12 is set or higher. In this state, the heat pump 19 and the pump 2 of the water circulation path 20
When activated, the hot water passing through the discharge pipe 6 circulates in the direction of arrow B through the bypass pipe 7 when the humidity is lower than the set temperature, and when the set temperature is reached, the water leaks through the IIA degree adjustment adjustment valve 3. The hot water is fed to the hot water storage tank 1 (in the direction of the arrow).

To create wind (5) It becomes a friend with sufficient humidity and heat. In other words, the temperature regulating valve 3 ensures that the hot water in the discharge pipe 6 does not become low temperature and always maintains a certain temperature or higher, and the water-refrigerant condenser 1
The amount of heat released at 1 is controlled. As a result, the water-refrigerant condenser can secure hot water at a predetermined temperature or higher, and the air-refrigerant condenser 12 can generate warm air. Furthermore, when the water temperature in the hot water storage tank 1 increases, the temperature of the water supplied to the water-refrigerant heat exchanger 4 increases, and the amount of heat released by the refrigerant to water decreases, so the amount of heat released to the air-refrigerant condenser 12 increases accordingly. increases, and the hot air temperature increases.
