A water chiller is a cooling device that provides constant temperature, constant flow, and constant pressure. It achieves refrigeration effects through steam compression or absorption cycles and is widely used in air conditioning, industrial refrigeration and other fields. Due to the temperature control requirements of cold water, there is a lack of corresponding buffering when using refrigerant. The low-temperature refrigerant will directly contact the higher temperature water chiller body, resulting in more intense heat exchange.
