And the return water circulating pump 71 and the water supply circulating pump 81 are started simultaneously, the direct heat supply circulating system can work under the action of pressure, and the heat exchange cavity of the heat exchanger 5 is utilized to supply heat to the water path so as to achieve the purpose of supplying heat to the tail-end heat supply equipment. Only the return water circulating pump 71 is started, the heat storage circulating system operates under the action of pressure, and the heat exchange cavity of the heat exchanger 5 is utilized to heat the stored water in the heat storage water tank 6, so that the purpose of storing heat by utilizing the heat storage water tank 6 is achieved, and the heat supply efficiency of the indirect heat supply circulating system is increased.
Circulation mode of the heat pump cycle system: the circulation system compresses medium operation through the compression pump 3, absorbs heat from outdoor air at the evaporator 2 and converts the heat into high-temperature gas, the high-temperature gas is recycled to the condensation cavity of the heat exchanger 5 through the reversing valve 4 to release heat, condense and liquefy, and the heat exchanger 5 completes heating of circulating water in the heat exchange cavity through the heat exchange structures (such as a plate heat exchanger) of the condensation cavity and the heat exchange cavity.
