What is the function of a solenoid valve in refrigeration?

A solenoid valve plays a crucial role in refrigeration systems by controlling the flow of refrigerant. When an electrical signal is applied to the solenoid, it activates the valve, allowing or restricting the passage of refrigerant through the system. This function is essential for managing the refrigerant flow according to the system's operational demands, such as during the cooling process or when specific conditions in the system change.

By regulating the refrigerant flow, the solenoid valve helps maintain efficient operation and system effectiveness, ensuring that the refrigeration cycle functions optimally. This response to electrical signals allows for automation and precise control in both commercial and residential refrigeration applications.
