Method for Removal of Refrigerant from Mobile Air Conditioning System to Quantify Charge Amount
Method for Removal of Refrigerant from Mobile Air Conditioning System to Quantify Charge Amount
This Standard provides an overview of results and requirements needed to remove refrigerant from a mobile air conditioning system for determining refrigerant emissions (leakage). This reclaim procedure for use on fleet vehicles in a field service environment should produce an accuracy and repeatability sufficient to determine refrigerant loss within 2 g. The removal of refrigerant from a mobile air conditioning system to determine the direct refrigerant emissions is a difficult procedure to do accurately. As part of the SAE I-MAC Cooperative Research Program a detail study was conducted on accurate removal of refrigerant from a mobile air conditioning system. Additional studies on the removal of HFC-134a from mobile air conditioning systems have been completed by others in the automobile industry. Use of commercially available equipment, including equipment meeting SAE J Standards, will not allow complete removal of refrigerant from a mobile air conditioning system in order to determine the direct refrigerant emissions. It is difficult and unreliable to remove refrigerant from mobile A/C systems and use this to quantify system emissions.
