Abstract :
Paying attention to using systems with higher efficiency in buildings is increasingly necessary due to high energy consumption in buildings and lack of energy sources. On the other hand, air conditioning systems and cooling equipment accounted for the largest percentage of building energy consumption. In this study some changes in direct evaporative cooling has been performed to reduce energy and water consumptions. A rotary cylindrical channel is assumed instead of the fixed evaporating chamber. Thus the pump is eliminated and the heat transfer coefficient is enhanced due to rotational water flow. The results are evaluated by changing input parameters such as different input speeds and different rotational speeds. The energy analysis is done and the effects of input parameters are investigated on cooling capacity, dew point effective, coefficient of performance and exergy loss.
