PVT-assisted heat pump for residential water heating

A group of scientists in China has designed a residential heat pump system with a potential cofficient of performance of 4. 271 at -5 C. The system is reportedly able to adjust the required pressures based on solar irradiance intensity and ambient temperatureScientists from Chongqing University in China have designed a solar-air composite dual-source heat pump system for water heating in self-built rural houses in the Beijing-Tianjin-Hebei region of China. "Our system can maintain stable heating performance even in adverse weather scenarios with low temperatures or limited solar radiation," the ...
