Through analyzing the development of water-source heat pump unit＇s energy efficiency standards, the requirements on the water-source heat pump unit＇s energy ef- ficiency stated in different standards are summarized. The theoretical limit of the energy efficiency of the water-source heat pump unit is analyzed theoretically, and the calculation method is given. According to the rated working condition stated in the GB/T 19409- 2013 Water-source （ground-source） heat pumps, the theoretical limits of ACOP for the water-source heat pump unit are deduced, which are 9.97, 10.91, 10. 16 and 10. 16 respectively for the water-loop type, the ground-water type, the buried-pipe type and the surface water type, which equal to about double corresponding energy-saving evaluation value, and it shows higher space existing for improving the energy efficiency of the watersource heat pump unit.
