摘要：The Earth Air Tunnel Heat Exchanger is more economical and effective system to maintain airtemperature comfortable to human body with respect to climate conditions. It is producing heating effect in winter andcooling effect in summer as it increases air temperature in winter and decreases air temperature in summer. In thisresearch paper Thermal Performance of Earth Air Tunnel Heat Exchanger in Series Connection Operating at TransientConditions installed at Bikaner was analyzed experimentally in the month of July & August over 8 days of period.Experimental setup of Earth Air Tunnel Heat Exchanger in Series Connection is installed at Mechanical EngineeringDepartment Government Engineering College Bikaner having mild steel pipe of 45.67ft length, 40mm inner diameterand 3mm thickness placed at a depth of 11ft. The Average Air Temperature Difference for 8 working days was found as11 ̊c, 12.13 ̊c, 13.26 ̊c, 14.52 ̊c, 15.65 ̊c & 16.87 ̊c corresponds to inlet air velocities 10m/s, 14m/s, 18m/s, 22m/s, 26m/s& 30m/s respectively. The Maximum Air Temperature Difference for 8 working days was found as 18.1 ̊c, 19.2 ̊c,20.1 ̊c, 20.7 ̊c, 21.7 ̊c & 22.9 ̊c corresponds to inlet air velocities 10m/s, 14m/s, 18m/s, 22m/s, 26m/s & 30m/srespectively. The Minimum Air Temperature Difference for 8 working days was found as 5.2 ̊c, 5.9 ̊c, 7.2 ̊c, 8.1 ̊c, 9.1 ̊c& 10.1 ̊c corresponds to inlet air velocities 10m/s, 14m/s, 18m/s, 22m/s, 26m/s & 30m/s respectively.
