摘要： Method of determining the presence of incondensable gases in a climate station cylinder for recharging motor vehicle air conditioning systems. One of the pressure sensors will be used that is present in the charging station and designed for monitoring the operations in the A/C system of the vehicle, placed on the low pressure LP and/or high pressure HP lines of the climate station, so that in case of verification of the incondensable gases, the control electronics opens a coolant charging valve and an HP/LP separating valve, thereby flooding the service pipes so as to receive the pressure signal from one of the service pressure sensors, LP or HP, of the station, and compare the value with the temperature T of the cylinder and check whether such pair of values is a corresponding parameter, without tolerances, of a pressure-temperature curve of the pure coolant.

摘要： A refrigerant recovery system includes a first oil separator including a chamber configured to receive refrigerant from an air conditioning system, a heat exchanger disposed within the first oil separator, and a compressor fluidly connected to the chamber and the heat exchanger. A first valve is disposed in a first flow line that is fluidly connected between an inlet of the first oil separator and a source of refrigerant and a second valve is disposed in a second flow line that fluidly connects the compressor and the heat exchanger. A controller is configured to open the first valve to enable refrigerant to pass into the chamber of the first oil separator, open the second valve so that a flow loop for refrigerant is formed between the heat exchanger and the compressor, activate the compressor to heat the refrigerant flowing through the flow loop, and subsequently commence a refrigerant recovery operation.
