Influence of supermarket environmental parameters on the frosting and defrosting of vertical multideck display cabinets.

Author(s) : TASSOU S. A., DATTA D.

Summary

Field and environmental chamber-based tests have shown that both ambient relative humidity and temperature of a store have a significant effect on the rate of frost formation on the evaporator coils, with the effect of relative humidity being much more pronounced than the effect of temperature. In supermarkets where a fixed-time defrost control strategy is employed, it is possible that cabinets are defrosted too infrequently or too frequently according to relative humidity. Considerable opportunity exists for the application of more sophisticated defrost control strategies, both to save energy and improve temperature control.
