0INTRODUCTION TO THE UTILIZATION OF EVAPORATIVE COOLING IN AUTOMOTIVE AIR CONDITIONING
ABSTRACT. THE EVAPORATIVE COOLING CONSISTS ON THE USE OF THE EVAPORATION OF WATER OR OTHER FLUID IN THE PRESENCE OF A DRAUGHT, WITH CONSEQUENT COOLING OF THE AIR. THE PRINCIPAL CHARACTERISTIC OF THIS PROCESS IS THE FACT THAT IT IS MORE EFFICIENT FOR HIGHER TEMPERATURES, EXACTLY WHEN THE COOLING HAS TO BE LARGER FOR THE HUMAN COMFORT. IT STILL HAS AS ATTRACTIVENESS THE LOW CONSUMPTION OF ENERGY, EASY MAINTENANCE, INSTALLATION AND OPERATION. THIS WORK PRESENTS AN INTRODUCTION TO THE USE OF AN AIR CONDITIONING SYSTEM THAT USES THE PROCESS OF EVAPORATIVE COOLING FOR THERMAL COMFORT IN AUTOMOTIVE VEHICLES. THIS PAPER ALSO PRESENTS THE OPERATION PRINCIPLES OF THE DIRECT AND INDIRECT COOLING SYSTEMS, THE THEORETICAL DEVELOPMENT OF THE EQUATIONS OF THE THERMAL CHANGES FOR THE INDIRECT SYSTEM AND THE ANALYSIS OF THE COEFFICIENT OF EFFECTIVENESS OF THE SYSTEM. IT DISCUSSES THE USE OF VAPOR COMPRESSION SYSTEM AS REINFORCEMENT TO THE EVAPORATIVE SYSTEM, AND IT ANALYZES THE EVAPORATIVE SYSTEM WITH DESICCANT COOLING FOR ADSORPTION AND IT COMENTS ABOUT THE VAPORIZATION OF THE WATER IN PRESSURES BELOW THE ATMOSPHERIC PRESSURE.
KEY-WORDS. EVAPORATIVE COOLING, AIR CONDITIONING, HEAT AND MASS TRANSFER.
