Randomized trial assesses temperature reduction in residential buildings using passive cooling systems, indicating significant improvement.
The thermal efficiency corresponding to an earth-to-air heat exchanger (EAHE) of d = 40 mm diameter, in the temperature climate zone similar to Beni Mellal, has been presented. This paper’s focus to determine the exact length of pipe that is required to reach desired comfort conditions in the exit of this system. TRNSYS software is used for detailed simulation of these summer characteristics. The results are encouraging; on the hottest day in July, EAHE reduces the air temperature at the inlet from 44.6 °C to an outlet temperature of about 27.85 °C producing a total cooling around 16 °C.
