Description

Technical Field

[0002] Existing heat source tower heat pump units and water source heat pump units mostly use shell and tube heat exchangers. The switching between summer cooling mode and winter heating mode is achieved by switching the water circuit and shares the same water circuit process. The inlet and outlet temperature difference between cooling mode and heating mode is different. Generally speaking, the inlet and outlet temperature difference of the heat exchanger is larger in heating mode, and the inlet and outlet temperature difference of the heat exchanger is smaller in cooling mode, resulting in a large difference in the circulating water flow rate flowing through the heat exchanger in the two modes. The water flow rate in heating mode is often much smaller than that in cooling mode. Therefore, the flow rate must be increased in the heating mode to meet the flow rate requirements of the heat exchanger.
