THE INTEREFFECT OF SUPERMARKET REFRIGERATION AND AIR CONDITIONING.

Author(s) : ADAMS P. Jr

Summary

THE SUPERMARKET IS THE ONLY COMMERCIAL BUILDING WITH A NEGATIVE COOLING LOAD. OPEN-DISPLAY FOOD REFRIGERATORS ABSORB BOTH SENSIBLE AND LATENT HEAT FROM THE STORE AMBIENT WITH A CONSEQUENT DIRECT EFFECT ON AIR CONDITIONING DESIGN. INTERNAL REFRIGERATOR TEMPERATURES ARE PROTECTED BY A REFRIGERATED AIR CURTAIN ACROSS THE DISPLAY OPENING. MIXING OF THE AIR CURTAIN WITH STORE AMBIENT CAUSES A HEAT EXCHANGE BETWEEN THE STORE AND THE REFRIGERATORS. BY-PRODUCTS OF THE MIXING ARE STRATIFIED COLD AIR NEAR THE FLOOR CAUSING CUSTOMER DISCOMFORT AND FROST ON LOW-TEMPERATURE EVAPORATORS.
