The AC low pressure switch is located in the low pressure side of the refrigerant circuit, typically near the evaporator. It acts as a pressure transducer that monitors the refrigerant pressure in the system. When the refrigerant pressure drops below a certain set point, the switch opens and breaks the electrical circuit to the compressor. This prevents the compressor from operating at a low pressure, which can cause it to overheat and fail.
The AC low pressure switch is an important component of refrigeration and air conditioning systems, as it helps to protect the compressor from damage and ensures its long-term reliability.
