REFRIGERATION INVENTORY CONTROL

摘要

An apparatus and process for controlling refrigeration in a closed cycle. An inventory recorder and controller in communication with major holdup locations in the refrigeration circuit determines the amount of the refrigerant in the system. The amount is measured, recorded and maintained by means responsive to the difference between a set value and the value measured by the inventory recorder and controller. The apparatus and method is applicable to a multicomponent refrigerant where individual control is maintained over each component.
