Question 2Refrigeration/AC - Assistant Engineer70% to pass
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?
AI Explanation
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 pressure in the system will rise dramatically due to the inability to dissipate heat. This high pressure will trigger the high-pressure cutout switch, which is a safety device designed to automatically shut down the compressor to prevent damage to the system. The other answer choices do not accurately describe the protective mechanism that will activate in this scenario.
