In commercial refrigeration, what does the thermostat primarily control?

In commercial refrigeration, the thermostat primarily controls the evaporator temperature by regulating the operation of the entire refrigeration system, including the compressor. The thermostat acts as a sensing device that monitors the temperature within the refrigerated space. When the temperature rises above a certain set point, the thermostat signals the compressor to activate, enabling the system to circulate refrigerant and return the temperature to the desired level.

The response of the thermostat is crucial, as it helps maintain consistent temperatures for perishables and products. While the liquid line solenoid valve plays a role in controlling the flow of refrigerant from the liquid line to the evaporator, its operation is actually tied to the thermostat’s directives based on the conditions detected.

This connection ensures that the refrigeration system operates efficiently and maintains optimal temperatures, which is critical in commercial settings where product quality and safety are of utmost importance.
