Abstract：As an alternative of coal-fired space heating, air source heat pump has a wide field of application with good prospect due to its advantages of high efficiency, energy saving and environmental protection. In severe cold environment,the thermal performance of conventional air-source heat pump decreases seriously, which limits its application in low temperature areas. According to the existing research status, this paper analyzes the characteristics and problems of several kinds of air source heat pump in low temperature. Furthermore, the development prospect of air source heat pump is also proposed in the aspects of compressor, defrosting and coupled technology, respectively.
