Question 69Refrigeration & AC - Assistant Engineer

The correct answer is B) high-pressure liquid line. The liquid indicator sight glass is typically located in the high-pressure liquid line of a refrigeration system. This position allows the operator to visually inspect the refrigerant charge and ensure that the system is properly filled. By observing the liquid refrigerant flowing through the sight glass, the operator can determine if the system has sufficient refrigerant charge. The other options are incorrect because the low-pressure liquid line, low-pressure vapor line, and high-pressure vapor line are not the typical locations for the liquid indicator sight glass. These lines do not provide the same level of visibility and information about the refrigerant charge as the high-pressure liquid line.
