Description

Air-side heat transfer correlations were developed to describe refrigerator components operating with variable-speed fans in an extensively instrumented test refrigerator. Only a few experimentally estimated parameters were needed to predict component performance over a wide range of steady-state operating conditions. Published correlations were found to represent adequately the velocity dependence of air-side heat transfer coefficients. By relating dome and discharge temperature of the compressor with a linear fit, it was possible to predict shell heat transfer over the same range of refrigerant-and-air-side conditions.
