What is the alternative name for the low-pressure cutout switch in a refrigeration system?

The alternative name for the low-pressure cutout switch in a refrigeration system is the suction pressure control switch. This switch is critical in maintaining the proper operation of the refrigeration system by monitoring the pressure on the suction side of the system, which corresponds to the refrigerant entering the compressor.

When the pressure drops below a certain threshold, the switch will cut off power to the compressor to prevent it from running under low-pressure conditions, which can lead to compressor damage and reduced efficiency. By regulating the suction pressure, this switch helps ensure that the system operates within safe and efficient parameters, allowing it to cool effectively.

This understanding is vital for maintaining system health and performance, as it provides a direct link between the refrigerant pressure and the functioning of the compressor, ultimately impacting the overall efficiency of the refrigeration cycle.
