Abstract

A method for distributing a refrigerant charge level in a refrigerant vapor compression system includes restarting a stopped refrigerant compression device in a first mode; operating a primary expansion device independent of refrigerant heat absorption heat exchanger superheat; comparing a condition at a refrigerant reservoir to a prescribed condition; wherein when the condition is below the prescribed condition for a prescribed interval, operating the primary expansion device to control the refrigerant heat absorption heat exchanger superheat; and transitioning the refrigerant vapor compression system to a second mode.
