摘要： 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.

摘要： A refrigerant recovery machine having two opposed and off-set pistons and its use are provided. The pistons are received in cylinders that are able to move depending on the alignment of the pistons. The two pistons in the compressor allow more volume of refrigerant than a single piston and because they are opposed and off-set allows for more even load on the motor.

摘要： A method for converting a refrigerant recovery unit from use with a first refrigerant to use with a second refrigerant includes the steps of opening, with a controller, solenoids along a refrigerant path to remove residue of the first refrigerant into a holding vessel, operating a vacuum pump, as indicated by the controller, to further remove the residue of the first refrigerant from the refrigerant path, introducing, via the controller, an amount of the second refrigerant into the refrigerant path, determining, with a refrigerant identifier, a purity of the second refrigerant in the refrigerant path. A kit is also provided to convert the refrigerant recovery unit for use with the first refrigerant to the second refrigerant.

摘要： A method of purging air from a tank includes opening, with a controller, a purging orifice on the tank to release a gas mixture contained within the tank, operating a timer to track multiple time intervals during which the purging orifice is open, each time interval having a beginning time and an ending time, determining an initial value of a system variable at each beginning time and a subsequent value of the system variable at each ending time, deriving a characteristic value of the gas mixture based on a change in the system variable from the initial value to the subsequent value measured over each time interval, and closing, with the controller, the purging orifice if a rate of change of the characteristic value over sequential time intervals is greater than or equal to a predetermined threshold rate of change value.
