摘　　要：为评价新型蓄能热泵热水机组的全年运行特性,该文实验测试了该机组在多种模式下的能效比;利用MATLAB和DeST软件模拟了机组在不同地域的全年运行性能,并与常规热水制备方式进行了经济性对比分析。结果表明,较大容积的蓄冷罐有利于提高机组的能效比;机组在夏热冬暖地区运行的全年能效比高于夏热冬冷地区20%;与燃气热水器相比,机组运行1.41年即可回收增加的初投资;该机组适于夏热冬暖地区既需要供热水又需要供冷的公共建筑。To evaluate the annual characteristics of the energy-storage heat pump water heater unit,its energy efficiency ratio（EER）is tested in different operation modes.The MATLAB and DeST softwares are used to simulate the annual running performances of the unit in different zones,and the economy comparation between the titled unit and other common producing hot water ways are made.The results show that the larger cooling storage tank has the higher EER,and the annual EER of the titled unit in the hot summer and warm winter zone is 20% higher than that in the hot summer and cold winter zone.Compared with the gas water heater,the heat pump water heater unit runs only 1.41 years for its recovery of the accessorial initial investment,and it is suitable for the big public constructions requiring hot water and cooling in the hot summer and warm winter zone.
