Earth-air heat exchangers

WebGround-air heat exchangers offer an innovative method of heating and cooling a building. Ventilation air is simply drawn through underground pipes at approx 1.5m, where the soil temperature is a constant 8-12°C. The soil temperature will pre-cool the air in the summer and pre-heat the air in winter. WebDownloadable (with restrictions)! Energy saving is a vital element in today's scenario. Earth Air Heat Exchangers (EAHE) is a technique that promotes energy savings. EAHE is a non-conventional technique that uses the earth's underground heat for space cooling/heating. In this article, review of different combinations of EAHEs is presented. The review …
