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