Earth air heat exchanger ppt
The earth–air heat exchanger (EAHE) is a promising technique which can effectively be used to reduce the heating/cooling load of a building by preheating the air in winter and vice versa in summer. In the last two decades, a lot of research has been done to develop analytical and numerical models for the analysis of EAHE systems. WebThe earth to air heat exchanger consists of two tubes of 0.315 m diameter buried at 2 m depth around the building. The length of each one is 50 m. They are designed to provide …
