Question 215Refrigeration & AC - Assistant Engineer

The correct answer is D) at the suction side of the compressor. The low-pressure cutout switch is designed to protect the compressor from damage due to low refrigerant pressure, which can occur on the suction side of the compressor. Connecting the sensing line at the suction side allows the switch to monitor the pressure and shut off the compressor if the pressure drops too low, preventing potential damage. The other options are incorrect because they do not represent the typical location for the low-pressure cutout switch's sensing line. The inlet side of the receiver, the discharge side of the compressor, and the outlet side of the receiver are not the appropriate locations for this critical safety device.
