As a result, the condensation pressure of the refrigerant increased, resulting in a decrease in efficiency. In order to solve the conventional problems as mentioned above,

Something like this has been proposed.

る。Effect of the present invention With the above-described configuration, the amount of circulating water from the hot water storage tank to the second heat exchanger that creates a medium temperature layer by heat exchange between the two-phase region and the liquid region of the refrigerant is equal to the hot water temperature at the outlet of the second heat exchanger. The system detects this and controls the rotational speed of the pump to ensure that a predetermined intermediate temperature layer is obtained. In addition, the first heat exchanger, which produces high-temperature hot water by heat exchange with the high-temperature gas region of the refrigerant, is located above the inlet of the medium-temperature layer into the hot water storage tank in the upper tank of the hot water storage tank, and is a natural convection type heat exchanger. This ensures that the water in the upper layer of the hot water storage tank reaches the specified high temperature. Therefore, by simply controlling the amount of circulating water flowing through the second heat exchanger, hot water with two temperature levels, high temperature water and medium temperature layer, can be obtained, and the condensation temperature and pressure to obtain the medium temperature layer in the second heat exchanger can be adjusted. This enables highly efficient operation.
