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 of adding refrigerant to an air conditioning system. The method includes measuring a first pressure inside of the air conditioning system and a second pressure inside of a container that holds refrigerant being added to the air conditioning system. The method also includes comparing the difference between the two measured pressures to empirical data in order to determine how long to pulse additional refrigerant into the air conditioning system. In addition, an apparatus configured to add refrigerant to an air conditioning system.

摘要： A method of charging or recharging an air conditioning wherein an initial amount of refrigerant is introduced, followed by additional introductions of refrigerant during injection pulses. The pulse periods are adjusted dynamically during the charging/recharging process based on feedback obtained after each pulse related to how much refrigerant was transferred during the previous pulse. Also, a system for implementing the above-mentioned method.

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.
