Low Pressure Cutout Switch Definition

Only leaking air conditioning systems have low refrigerant levels.

Low pressure cutout switch definition.

This type of control is most popular in small refrigerated boxes such as beer coolers. This protects the compressor from damage. The switch arm can be pressed and the cut out reset after the cause of the over pressure has been found and rectified. The low water pressure switch attachment drops to turn off the pump when it loses its prime and the pressure drops to a specific low pressure cut off point.

To control box temperature with a low pressure control the system must use a thermostatic expansion valve non bleed type. Mounted on low pressure side of compressor. Low pressure cutout switch prevents system damage due to low pressure or low refrigerant charge by disabling a c compressor when pressure drops below reset point. Low pressure cut out to protect the compressor against low pressure in the system and to avoid the ingress of air into the system if a vacuum is generated in the lines a low pressure cut out is provided.

Allows compressor to resume when pressure rises above set point.

Refrigerant does not wear out or evaporate. An automotive air conditioner s pressure switch cycles the vehicle s compressor on and off when the refrigerant pressure falls below an acceptable level.
