State of the Art of Air-source Heat Pump for Cold Regions
MetadataShow full item record
In this paper, research on air source heat pump systems for cold regions in recent years is first summarized and compared. These systems can be divided into three kinds: a single-stage compression heat pump, liquid/vapor injection heat pump, and a two-stage heat pump. Finally, our research with a two-stage compression variable frequency air source heat pump is presented. A two-control-model with the priority target as COP or heating capacity is advanced. The experimental results show that the COP of this heat pump system is over 2, the compressor discharge temperature under 120, and the heating capacity can meet the heating load needed when the condensing temperature is 50 and outdoor air temperature is over -18.
