A British-Chinese research group has developed a novel heat pump concept consisting of a heat pump, the PCM tank, and tube solar heat collectors. Intended for demand shifting in space heating and domestic hot water (DHW) applications, the system is reportedly able to achieve a higher coefficient of performance than conventional heat pumps.An international group of researchers led by the University of Nottingham in the United Kingdom has developed a novel residential direct-expansion solar-assisted heat pump (DX-SAHP) system that utilizes a heat storage tank made of a phase change material (PCM). ...Den vollständigen Artikel lesen ...
