Abstract

See full text

A method and charging apparatus for adding refrigerant to an air conditioning system are provided. The method includes calculating a temperature differential by measuring a first temperature of a refrigerant inside of a refrigerant container and measuring a second temperature either at the air conditioning system or the ambient temperature. The method further includes using the temperature differential to calculate a compensation amount of refrigerant to add to a previously determined recommended amount of refrigerant based on the type of air conditioning system being charged.
