Ezperiment Study on Low-Temperature Heating Performance of a New Solar-Air Multi-source Heat Pump
In view of the poor low-temperature heating performance of single air-source heat pump (S-ASHP) in winter, a new solar-air multisource heat pump (SA-MSHP) which uses the solar-air multi-source heat exchanger (SAMSHE) as the core component is presented. In order to study the low-temperature heating performance of S-ASHP and SA-MSHP, experiment tables of the two heat pumps are constructed. The results show that the low-temperature heating performance of SA-MSHP is better than S-ASHP obviously. In the ultra-low temperature condition and the outdoor temperature is -15 ℃, SA-MSHP can also run stably. Heating capacity increase about 45％ and COP increase about 50％ compared with S-ASHP. It has important significance for applying SA-MSHP to improve the low-temperature heating performance and enlarge the application range of air-source heat pump. It also has important significance to accelerate the spread of solar heat pump in building air conditioning field.
