Liquid line charge compensator

Abstract

An apparatus and method for reducing discharge pressure in a Heating, Ventilating, and Air Conditioning system. The apparatus has a compensator reservoir and a compensator line. The compensator line connects the compensator reservoir and a liquid line. The liquid line connects a condenser and an evaporator. The compensator line has a connection to the compensator reservoir and a connection to the liquid line. In the method, a controller checks for one or more conditions indicating a likelihood of high discharge pressure. The controller finds a condition indicating a likelihood of high discharge pressure. In response to finding the condition, the controller closes a compensator valve after a set amount of time. The controller reopens the compensator valve.
