THERMODYNAMIC ANALYSIS OF YEAR ROUND AIR CONDITIONING SYSTEM FOR VARIABLE WET BULB TEMPERATURE OF OUTLET AIR OF PRE-HEATING COIL (COLD AND DRY WEATHER)

This paper presents a study on different kinds of air conditioning systems in comparison to existing one to use through of the year. Mainly the system imparts all three regular weather conditions. Like hot and dry, hot and wet and cool and dry. For this the room condition will be fixed 25 °C dry bulb temperature (DBT) and 50% relative humidity. In the present paper, for maintaining room condition thermodynamic simulation is being done. If wet bulb temperature(WBT) of outlet air of pre-heating coil cooling is increased(14.5 to 17 °C) for cold and dry weather condition then the year round air conditioning system equipments change own parameters like pre-heating coil temperature, saturation efficiency of evaporative cooler and re-heating coil temperature to maintain the room condition. The paper also shows the variation in supply condition of air and volume of cellulose cooling pad.
