Moisture-Indicating Sight Glass

A moisture-indicating sight glass is installed in the liquid line, upstream of the expansion valve, and permits the operator to observe the condition of the refrigerant prior to entering the expansion valve. The value of the sight glass is in its moisture indication ability—the sight glass should not be used to determine system refrigerant charge or subcooling. Actual temperature and pressure measurements are required to determine proper charge and subcooling.

With the sight glass installed directly ahead of the expansion valve, it can also be used to detect the presence of bubbles in the liquid line. This would indicate that some of the liquid refrigerant has flashed into vapor upstream of the expansion valve. Since the expansion valve is designed to control the flow of liquid refrigerant only, the presence of refrigerant vapor results in a reduction in the quantity of liquid refrigerant being fed to the evaporator. There are many potential causes of liquid refrigerant flashing. The sight glass can alert the operator to the condition.
