Summary

1. HYDROCOOLING: WITH IMMERSION OR WATER SPRAY; WITH AND WITHOUT CONVEYOR BELT; EVAPORATORS: PIPE COIL [R12, UP TO ABOUT 25 KW (20,000 FG/H)], COIL (AMMONIA OR R22, MORE THAN 25 KW). 2. VACUUM COOLING: REFRIGERATING AND VACUUM PRO-DUCTION SYSTEMS. 3. AIR-BLAST SYSTEM: AIR DISTRIBUTION: FALSE CEILING OR AIR DUCTS; VERTICAL AIR JETS; QUICK-COOLING CELLS; INSIDE PLASTIC CONTAINERS. 4. ICING. 5. ECONOMIC CALCULATION OF THE COOLING LOAD AND REFRIGERATING CAPACITY OF THE PLANT (EXAMPLE). 6. AIR HUMIDIFYING: RELATIONSHIP BETWEEN TEMPERATURE DIFFERENCE (EVAPORATOR/AIR) AND RH. METHODS FOR IMPROVING THE RH: IMMERSION OF THE BOXES BEFORE COOLING, COOLING THE AIR BY COLD WATER, WATER SPRAY (DISCS, INJECTORS), USE OF SPRAY-TYPE EVAPORATORS. J.G.
