Question 19Refrigeration & AC - 1st Asst/Chief

The correct answer is C) the compressor will shut down by the action of the high pressure cutout switch. In a refrigeration system without a water failure switch, if the cooling water to the condenser fails, the refrigerant will not be able to dissipate heat effectively. This will cause the refrigerant pressure in the high-pressure side of the system to rise rapidly. The high pressure cutout switch is a safety device designed to detect this high pressure condition and automatically shut down the compressor to prevent damage to the system. The other options are incorrect because they do not directly address the high pressure issue caused by the loss of condenser cooling water.
