It is mainly used in HVAC systems. It can realize the control, regulation, and distribution functions of hydraulic systems, thereby improving the system's operating efficiency and stability.

[0003] In existing technologies, filters are usually installed at the water inlet of the water supply device to reduce hydraulic loss by ensuring the cleanliness of the incoming water. However, during the operation of the heat pump, due to changes in water temperature, some scale will always precipitate in the pipeline, which will affect the water supply. Moreover, the filter needs to be cleaned after long-term use, and cleaning the filter in the water circuit requires stopping the machine, which is cumbersome and affects the stable use of the heat pump.
