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.

摘要： 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.

摘要： A fitting for releasably coupling two structures and for maintaining fluid communication between the two structures has a first and second fitting member. The first fitting member includes a first ferromagnetic coupling element, and the second fitting member includes a second ferromagnetic coupling element. The first and second fitting members are constructed and arranged so as to be moved into engaged relation with one another and to be moved apart from on another so as to be separate from one another. Magnetic attraction between the first and second fitting members maintains the fitting members in engagement, and the fitting members are decoupled by applying force sufficient to overcome the magnetic attraction.

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.
