  • Gas analyzer system configured to determine the concentration of a refrigerant gas and/or the concentration of contaminant gases in an automotive air conditioning system
    Patent number: 8950237
    Abstract: A gas analyzer system to determine the concentration of gases in an automotive air conditioning system comprising: an infrared multi-detector device equipped with a gas analysis chamber; an emitter source emitting infrared radiation in the analysis chamber; infrared multi-detectors generating an electrical measurement quantity based on the absorption of radiation by the gas; a suction pump creating a depression inside the analysis chamber; and an electronic control unit determining a main automotive refrigerant gas concentration and the contaminant gases concentration, based on electrical measurement quantities provided by the multi-detectors and a reference electrical quantity. The control unit controls the pump to suck the gases in the analysis chamber until a condition of absence of gases is achieved, wherein the internal pressure of the chamber reaches a minimum pressure, and then determines the reference electrical quantity, based on the electrical quantity generated in the condition of absence of gases.
