An experimental and modeling study for a novel Bank type earth air heat exchanger for the summer season using full factorial design

Abstract The current study reports the modeling and experimental study of a novel Bank type earth air heat exchanger for both hot and humid and hot and dry weather of Ferozepur. The air has been flown through the bank in the induced mode in which uniform flow is achieved through all parallel pipes. The experimental work was followed by systematically designing experiments using the reduced quartic model of the full factorial designing technique. The earth's undisturbed temperature was 28°C at a depth of 2 m below the earth's surface at the place of study. The present study is better than the earlier reported shapes because the dry bulb temperature has moved down to 29.8°C . The 2-factor as well as 3-factor interactions were studied. The desirability for hot and dry weather ranges from 0.813 to 1.00, and for hot and humid weather ranges from 0.603 to 0.736.
