Performance Estimation of Heat Exchanger Operates By Evaporative Cooling Manner

In this study the design and installation of evaporative air cooler was carried out using completely outdoor air (fresh air) according to two stage evaporative cooling principle. The laboratory equipment was installed by designing and manufacturing a cross flow plate heat exchanger, where a...
