Air-side heat transfer correlations were developed to describe variable conductance models for thecondenser and evaporator. Few experimentally estimated parameters described well the changes of refrigerant andair-side conditions over a wide range of steady-state operating conditions for the extensively instrumented testrefrigerator. Existing empirical correlations that describe the difficult geometry of the heat exchangers weresuccessful for the condenser, but not as successful for the evaporator. By relating dome and discharge temperatureof the compressor with a linear fit, which could be accurately estimated if compressor manufacturers disclosedinformation for one more point other than the rating point and included the dome temperature, an experimentallyestimated air-side heat transfer correlation described well the compressor for the same changes of refrigerant and airsideconditions.
