Researchers in India have combined PV generation with heat produced by an earth-to-air heat exchanger to provide buildings with space heating and cooling. They say the proposed system could result in an annual energy gain of 8116.7 kWh.Researchers at the Central University of Jharkhand in India have developed a thermal energy system for buildings that uses an earth-to-air heat exchanger (EAHE) system powered by a standalone PV system. An EAHE is a passive geothermic solution consisting of a buried pipe system circulating fresh air. These systems are commonly used to warm up fresh air in buildings ...Den vollständigen Artikel lesen ...
