摘　　要： 分析水源热泵机组能效相关标准的发展,总结不同标准对水源热泵机组的能效要求,理论分析水源热泵机组的能效理论极限值,得出其计算方法。结合现行GB/T19409—2013《水(地)源热泵机组》规定的额定工况条件,推导计算出水源热泵机组ACOP理论极限值:水环式为9.97,地下水式为10.91,地埋管式为10.16,地表水式为10.16,相当于对应节能评价值的2倍左右,说明提高水源热泵机组能效具有较大的空间。 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.
