摘      要：Earth Air Tunnel Heat Exchanger(EATHE)systems are not so much popular in India because of restricted acces-sibility of ground space in majority of residential and commercial *** the present article,thermal perfor-mance of newly designed helical shaped EATHE system has been compared with conventional U-shaped EATHE system by keeping similar geometrical and operational configuration for the summer(April-June)and winter(December-February),*** this regard,therefore,numerical model of both EATHE systems have been designed and experimentally *** thermal performance of both EATHE systems has been compared in terms of outlet air temperature and *** present numerical study suggested that the newly designed helical EATHE system exhibits better thermal performance with lower ground requirement as compared to con-ventional U-shaped EATHE *** evaluate the thermal comfort potential of EATHE system in office buildings of India,composite climate specific adaptive thermal comfort boundaries has been *** detailed thermal performance behaviour of the EATHE system suggests that an additional 80%of the time;ambient air condi-tions became thermally comfortable during peak summer *** addition,analysis of the results revealed that EATHE system has more potential during heating operation mode to maintain indoor comfort in winter season of composite climate in India.
