ABSTRACT:
A portable recovery unit for automatically filling a background tank of blended refrigerant includes a main tank for holding recovered refrigerant from a vehicle A/C system which has a first chemical composition, and an auxiliary tank for holding an auxiliary supply of fresh refrigerant which has a second refrigerant composition. The auxiliary tank is arranged in fluid communication with the main tank so that fluid can be transferred from the auxiliary tank to the main tank. An electronic controller controls the flow of fluid from the auxiliary tank to the main tank. A refrigerant identifier is coupled to the main tank to sample and analyze the refrigerant in the main tank in order to determine the chemical composition of the refrigerant in the main tank, so the refrigerant in the main tank can be purified to an acceptable level based on that analysis.
