• Abstract

EATHE is a system which maintains surroundings temperature comfortable to human body and has no bad impact on environment of earth like other air-conditioning system i.e. works on VCRC which uses CFCs as refrigerant i.e. causes global warming and ozone layer depletion. In this research paper, Thermal Performance of Simple EATHE is developed by introducing new concept i.e. Hybrid EATHE in Series Connection Coupled with Water Cooled Heat Exchanger in which outlet air temperature of Simple EATHE is further decreased by using wastage water of water cooler i.e. flowing inside the Water Cooled Heat Exchanger which is coupled at outlet of EATHE in Series Connection. The setup of system is installed at Mechanical Engineering Department Government Engineering College Bikaner. Experimental Analysis was carried out on the system in the month of September. The Minimum, Average & Maximum Air Temperature Difference was found as 11.7̊c, 16.27̊c & 23.7̊c respectively.
