Air source heat pumps for space heating and cooling, 41st Informatory Note on Refrigeration Technologies.

Author(s) : LI X., WANG B.

Type of article: Techincal Brief

Summary

Air source heat pump is an energy-efficient technology that allows heating at different ambient temperatures. The normal heating efficiency of ASHP is 3 to 4 times higher than that of direct electric heating. ASHPs can be used in different climates, from -25°C to +50°C, by developing technologies such as variable frequency compressor, cascade ASHP, two-stage compression and quasi two-stage compression.
This Informatory Note provides detailed information about the principles and state of the art of ASHP technologies. It also outlines anti-frosting strategies and defrosting methods as well as alternative refrigerants with the lowest environmental impact. Finally, it presents the ASHP applications all over the world and highlights the measures to be taken to accelerate the use of ASHPs in buildings.
