Summary

1. COMPARISON OF CENTRAL PLANT AND DECENTRALIZED PLANT. ACCORDING TO THE A. THE ADVANTAGES OF A CENTRAL PLANT ARE: FEWER COMPRESSORS (3 TO 6 INSTEAD OF 25-30) AND FEWER CASES OF BREAKDOWN; EASIER MAINTENANCE; SURFACE OF MACHINE ROOM REDUCED; LOWER COST (PIPING, ELECTRICAL EQUIPMENT, MANPOWER); HIGHER RELIABILITY (INTERCONNECTION OF COMPRESSORS; LOWER PROBABILITY OF BREAKDOWN). 2. COMPARISON OF WATER-COOLED AND AIR-COOLED CONDENSERS. AIR-COOLED CONDENSERS ARE MORE ADVANTAGEOUS: EASIER MAINTENANCE, SAME OPERATION COSTS. 3. OTHER SUITABLE FEATURES OF REFRIGERATING PLANTS: AUTOMATIC DEFROSTING; USE OF R502. 4. ENERGY SAVINGS A) RECOVERY OF CONDENSATION HEAT: WATER HEATING (HIGH CONSUMPTION OF HOT WATER IN SUPERMARKETS) OR AIR HEATING (SELLING AREA), HOT GAS DEFROSTING. B) DEFROSTING THE EVAPORATORS OF DISPLAY CASES BY AIR COMING FROM THE SELLING AREA. C) LIMITATION OF THE RELATIVE HUMIDITY IN THE SELLING AREA 55% AT 298 K (25C)IN ORDER TO REDUCE F DISPLAY CASES. D) LOCATION OF THE SUCTION INLET OF THE AIR CONDITIONING SYSTEM IN THE COLDEST ZONE OF THE SELLING AREA (RECOVERY OF THE COLD AIR COMING FROM DISPLAY CASES). E) USE OF A PROGRAMMED SYSTEM CONTROLLING THE LIGHTING, AIR CONDITIONING, REFRIGERATING PLANT, ETC. J.G.
