Abstract
Herein is disclosed an electronically controlled apparatus for accurately charging and/or venting refrigerant for an air conditioning system having an air cooled condenser and capillary tube control. The system includes means for stabilizing the sensed pressure values, means for rapidly charging a refrigeration system having a gross undercharge, means for automatically terminating the operation of the charge adjuster and means utilizing condenser heat to increase the speed at which refrigerant may be added to the refrigeration apparatus.
