Abstract
In the Sahelian zone, air cooling in house by air-soil heat exchanger is an alternative in the context of insufficient of electrical energy. This work is about cooling of a habitat in Ouagadougou by numerical approach. Numerical results provided a better understanding of the influence of parameters such as tube length, air velocity and soil temperature on the thermal efficiency of this system. We analyze the effects of parameters such as renewal air flow rate, soil temperature and number of tubes. The results show that during the hot periods of the day, the Canadian well cool air in habitat.
Keywords: Sahelian zone, cooling, house, air-soil heat exchanger.
