Performance Evaluation of Mist Spray Direct Evaporative Cooler through Experimentation and its Comparasion with Conventional Evaporative Cooler with Honeycomb Pad Arrangement
In residential building, air conditioning system is one of the major energy consuming appliances. Evaporative
cooling systems are mostly preferred as an alternative to compressor-based air conditioning systems, sacrificing comfort to a
certain level. The performance of a Mist Spray Direct Evaporative Cooler (MSDEC) is evaluated basically on four
parameters viz. Reduction in air temperature, saturation efficiency, cooling capacity, and noise level. This research article
focuses on development of MSDEC, its performance evaluation and comparison with the Conventional Evaporative Cooler
with Honeycomb Pad Arrangement (CECHPA) under the same test conditions. Results indicate performance of MSDEC is
improved significantly in respect of a drop in temperature, saturation efficiency and enhanced cooling capacity with a
considerable saving in energy input, reduction in water consumption and noise level. The unit is almost free from fungus and
mosquitoes as it requires no water storage.
