Question 142Refrigeration & AC - QMED

The correct answer is A) Liquid line moisture indicating sight glass. The liquid line moisture indicating sight glass is the device that will indicate whether or not a refrigeration system's dehydrator continues to be capable of removing moisture from the circulating refrigerant. This sight glass allows the operator to visually inspect the refrigerant for any signs of moisture, which would indicate that the dehydrator is no longer effectively removing moisture from the system. The other options are not the correct devices for this purpose. The McLeod gage is used to measure the vacuum in a refrigeration system, the dryer sensing bulb is used to monitor the temperature of the refrigerant, and the particulate test is used to check for contaminants in the refrigerant, but none of these devices can directly indicate the moisture-removing capability of the dehydrator.
