According to operation characteristic for air-source heat pumps, this paper presents recommendations that air-source heat pump products should give its season energy efficiencies indices in China, and discusses the necessity, the importance, pressing and possibility to formulate test standard on air-source heat pump performance in our country. On the basis of current developing level of heat pump technology internationally, this paper gives suggestions about introducing new techniques and improving product structure design, and discusses the necessity and the importance setting up advanced laboratory of air-source heat pumps in manufacturers and making up test centers in nationwide. In order to developing air-source heat pump industry, also need attentively use air-source heat pumps. Author also presents suggestions for improving design selection and operation management in this paper.
