[0002] Heat pump units are widely used in heating, cooling, and hot water supply due to their high efficiency, energy saving, and environmental friendliness. However, current heat pump unit control devices have some shortcomings, which restrict the full realization of the heat pump system's performance.

[0003] Some traditional control devices only have basic start-stop control and temperature regulation functions, and cannot dynamically adjust the operating parameters of the heat pump unit according to factors such as ambient temperature and load demand. For example, when the ambient temperature is low, the compressor's operating frequency and refrigerant flow cannot be optimized in time, resulting in low heating efficiency and increased energy consumption; when the load changes, it cannot respond and adjust quickly, affecting the heating or cooling effect. To address this, we have designed a control device for heat pump units. Utility Model Content
