Design, Construction And Performance Evaluation of Earth-To Air Heat Exchanger For Room Heating Applications
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
Earth air heat exchanger (EAHX) is a subterranean ventilation system that explores soil temperature below the surface to pre-cool or pre-heat ventilation air. Performance of the earth air heat exchanger varies with climatic and soil condition of the area. In this paper, an Earth air heat exchanger (EAHX) was designed constructed and installed and its actual field performance was evaluated. The results suggested that the earth air heat exchanger alone is not sufficient to create thermal comfort, but can provide significant portion of heating load. The average coefficient of performance (COP) in the cold (Hamadan) was 3.2.The earth air heat exchanger was able to raised the cold ambient air by 3.40C during cold season
