Calculation of humidity effects on energy requirements of refrigerated display cases.

Author(s) : HOWELL R. H.

Summary

Methods have been developed that allow the designer or engineer to estimate the savings realized in display case operation by lowering store relative humidity. When the relative humidity was lowered from 55 to 35%, the majority of the display cases saved 20 to 30% in compressor energy, 40 to 60% in defrost energy, and 19 to 73% in antisweat heater operation. At the same time, the operating costs for the store air-conditioning system increased by 4 to 8%.
