Direct expansion solar heat pumps for residential applications

Scientists in India have conducted an extensive review of all direct expansion solar heat pump technology in an effort to broaden its residential adoption. Such system can psroduce hot water from 15 C to 60 C at an average coefficient of performance of 1. 5 to 4. 5. A group of researchers from MIT World Peace University in India has conducted an extensive review of all direct expansion solar heat pump (DX-SHP) technology for domestic heating applications like water heating, solar drying, space heating, and industrial process heating. These systems can reportedly produce hot water from 15 C to ...
