METHOD AND APPARATUS FOR REFRIGERANT DETECTOR CALIBRATION CONFIRMATION

摘要

A refrigerant detector testing system according to aspects of the disclosureincludes a metering orifice formed in a suction line that is disposed betweenan evaporator coiland a compressor, a valve fluidly coupled to the metering orifice, aconnecting tube fluidlycoupled to the valve on a side opposite the metering orifice, a mixing devicehaving an inputorifice fluidly coupled to the connecting tube. In some embodiments, themixing device includesan air intake disposed proximate the input orifice, a throttling portiondownstream of the inputorifice and the air intake, the throttling portion having a reduced cross-sectional area, and adiffuser section positioned downstream of the throttling portion, the diffusersection having anoutput orifice. According to aspects of the disclosure, a refrigerant detectorfluidly exposed tothe output orifice.
