Abstract :
A new solar-air multi-source heat pump (SA-MSHP) was designed. According to the technical characteristics of heating performance of SA-MSHP in winter, two important concepts were proposed. The two concepts were “the two heat sources effectively composite heat transfer temperature difference (THSECHTTD)” and “the maximum two heat sources effectively composite heat transfer temperature difference (MTHSECHTTD)”. In this paper, the THSECHTTD in different solar hot water flows and the effect of the THSECHTTD on the heating performance of SA-MSHP were studied by experiments.
