摘　　要：在高水温空气源热泵热水器的研制中,采用去除有害热量设计技术,使热泵热水器最高热水温度由常规设计的60℃提高到75℃以上,同时将热泵热水器的性能系数提高到2.6 W/W。该热泵热水器在-11℃低环境温度时仍能正常运行,解决了热泵热水器在北方低环境温度使用时热水温度不足问题,达到普通热泵热水器进入北方市场的目的。In the research and development of high-temperature air-source heat pump water heater,using technology of removing harmful heat design,the highest temperature of hot water of heat pump water heater is improved from conventional design of 60 ℃ to over 75 ℃,and energy efficiency coefficient of the heat pump water heater is increased to2.6 W/W.The heat pump water heater can still operate normally in low temperature of-11 ℃.The design solves the issue that the hot water temperature is inadequate when using the heat pump water heater in the low temperature environment of the northern,and reaches the purpose of ordinary heat pump water heater approaching the north market.
