| description | An earth-air heat exchanger (EAHX), also known as an earth tube heat exchanger
or Canadian well, is a system for cooling and heating buildings using the ground as a heat
sink/source. This study examines the ground temperature gradient and the performance of
an EAHX performance in Burkina Faso. Ground temperature measurements were made at
depths of 0.5 m, 1.0 m and 1.5 m. At the hottest time of the day, 15:00, the average outside
temperature was 39.0°C, but the average temperature 1.5 m underground was 30.4°C. A
clear phase shift was observed between the maximum outside temperature and the
maximum ground temperature: the time of the day when the outside temperature is highest
corresponds to the time when the underground temperature was lowest. The EAHX was 25 m
long, 1.5 m underground and used a 95 m3/hr ventilator. It was able to cool the air drawn in
from the outside by 7.6°C. |
