In a refrigeration system that is not protected by a water failure switch, if the cooling water to the condenser fails, what will be the result for protective purposes?

Correct Answer: Option C — the compressor will shut down by the action of the high pressure cutout switch

Condenser cooling water failure halts heat rejection, causing liquid refrigerant temperatures and head pressures to spike rapidly. The high-pressure cutout switch trips to protect the compressor from mechanical over-pressurization.
