Abstract:
In this thesis the performance of an indirect evaporative cooler is experimentally analyzed in terms of its thermal effectiveness. A heat and mass exchanger (HMX) using a cross-flow pattern incorporating Maisotsenko cycle (M-cycle) is designed and fabricated having a compact channel width to height ratio, proper water supply system for wet channels and more efficient moisture absorbing material on the wet channel. To provide continues supply of cooling water to wet channels, force & induced combined cooling tower is design to reduce more temperature at outlet. Experimental investigations are conducted under various operating conditions of inlet air including its humidity, temperature and velocity along with water temperature. The experimental results indicate that temperature difference is 16⁰C at different air velocities and inlet temperature. The proposed framework design gives better efficiency when contrasted with the previous work, the outcomes were examined with the impact of various factors. Thus the proposed cooler has more efficient design that is commercially suitable Moreover, the overall performance of the improved design is found more compact and efficient as compared to previous system.
