Among the components of industrial chillers, expansion valves are a very important component of equipment and play an important role in the refrigeration of industrial chillers. The expansion valve is both a flow regulating valve in the chiller refrigeration system and a throttle valve in the refrigeration device. It is installed between the drying filter and the evaporator in the refrigeration device, and its temperature sensing package is wrapped in the evaporator. At the exit, avoid damage to the expansion valve when using it.
In addition, the effect of the expansion valve on the cooling effect in industrial chillers is not negligible. According to some industrial chiller manufacturers, the main function of the expansion valve in industrial chillers is to reduce the pressure of the high-pressure normal-temperature refrigerant liquid when flowing through the thermal expansion valve, and become a low-temperature low-pressure refrigerant wet steam (most It is a liquid, a small part is steam) enters the evaporator, vaporizes heat in the evaporator, and achieves the purpose of cooling and cooling.
