Abstract   This paper analyzed the application status and development trend of water-source heat pump in china, and
the necessity to establish the energy efficiency standards of water-source heat pump. Based on the analysis to status of
energy efficiency standards in refrigeration and air-condition industry, and according to its characteristics such as lots of
sorts and capacity grades, the reflections to establish the energy efficiency standards of water-source heat pump were
presented. Meanwhile, thermodynamics perfect ratio (η) was introduced to replace performance coefficient (cop) and
energy efficiency ratio (EER) to be the new energy efficiency index. This paper also put forward a new ideal of using
the linear relationship between thermodynamics perfect ratio and refrigerating capacity to replace establishing energy
efficiency grades by capacity. These will be supports to establish the energy efficiency standards of water-source heat
pump.
