Abstract

Nowadays, keeping environment at comfort zone with conventional cooler become expensive, especially in wide and semi outdoor spaces. Evaporative cooler which offer a healthy, non-harmful materials, and low cost can be an alternative to keep environment healthy and comfortable. The objective of this experiment is to determine and compare the performance of direct evaporative cooler embedded with heat pipes and without heat pipes. Heat pipes are placed in the section before cooling pad and work as indirect stage. Evaporator sections of heat pipe are placed before cooling pad and the condenser section are placed in the addition sump. The results show that the saturation efficiency of both system increase along with the increase in inlet temperature and decrease along with the decrease in relative humidity. The saturation efficiency also decreases along with the increase in air velocity. The results also show that the saturation efficiency of modified evaporative cooler using heat pipe is higher than direct evaporative cooler. The addition of heat pipes can increase the saturation efficiency of direct evaporative cooler up to 1.03 without addition more power consumption.
