Exam 10: System Charging

If the tank is a reusable tank, there are no check valves and system refrigerant can enter the tank as long as the system pressure is higher than the pressure in the tank.

Glide is the range of temperatures/pressures in which a blended refrigerant will condense.

If the pressure in the refrigerant cylinder drops down too low to charge a system (cylinder pressure = low side system pressure), how can the technician increase the cylinder pressure?

A graduated cylinder charging device is a device that ____.

As refrigerant vapor is removed from a supply cylinder, the pressure in the supply cylinder will ____________________.

If 22 oz. of refrigerant are to be added to a refrigeration system and the supply cylinder weighs 24 lb. 12 oz. before any is added, what will be the supply cylinder weight after the system has been charged?

When adding refrigerant in vapor form to an operating refrigeration system, the refrigerant must be added to the low-pressure side of the system .
