Operation characteristics of a novel dual source multi-functional heat pump system under various working modes

The dual source multi-functional heat pump (DMHP) system, which can adopt air source and solar energy to provide air conditioning and domestic water for building all the year round, is the integration of solar thermal collecting system and multi-functional heat pump system. This paper presents an investigation into the operation characteristics of the novel DMHP system under various working modes by theoretical and experimental methods. For each...
