Liquid Receiver

The liquid receiver tank for liquid refrigerant. Refrigerant is pumped out of the various parts and stored in liquid receiver in the course of servicing. It makes use of a quantity of refrigerant in the system, the less important. Sometimes, receiver, built-in in the lower end of the condenser. Most receivers have service valves. Thin copper mesh at the outlet prevents from dirt refrigerant control valves.

Liquid receivers are often found in systems that use the low side of the float or expansion valve type of refrigerant management. Capillary tube systems do not use liquid receivers (All liquid refrigerant is stored in the evaporator off part of its cycle). There is an increased use of closed systems and capillary tube refrigerant management. This has reduced the need for liquid receivers in the domestic systems and many small commercial units.

In large commercial systems, the receiver provides reserve of liquid refrigerant. This ensures that the liquid line, refrigerant sub-cooling and free flash strip. The recipient shall provide sufficient space for refrigerant during automatic pumpdowns (thawing purposes, and when some of the evaporators is not used). Some systems that have open-air cooled condenser, need a room in receiver for the optional refrigerant. Without extra room, fluid partially fills the condenser when the head pressure is too low. The liquid will move through the condenser...
