Effects of indoor relative humidity on refrigerated display case performance.

Résumé

Refrigerated display cases are normally rated at a store environment of 24 deg C and a relative humidity of 55%. If the store can be maintained at lower relative humidities, significant quantities of compressor energy, defrost energy and anti-condensation heater energy can be saved. In this study a model was developed for a 4650 m2 (50,000 ft2) food store with a typical mix and quantity of refrigerated display cases. Moisture balances were done for a typical day in a typical store for each month of the year yielding a twenty-four hour variation in the store relative humidity. The total store energy bill (display cases, air-conditioning and lights) would be reduced by 4.7 for 5% lowering change in relative humidity. These are significant cost savings for a supermarket.
