海尔变频空气能热水器(产品型号KF75/200-AE5、KF110/300-AE5)首次应用了“面向模式可选的热泵热水器全工况变频控制节能技术”。

产品具有以下特点：①额定工况最大能效系数COP达到5.0W/W超出国标限定值1.6W/W且高出国标一级能效值（4.2W/W）水平0.8W/W；②超低温环境-7℃制热水时间较普通热泵热水器缩短一半，制热量衰减小，COP高；③纯热泵最低可在-15℃环境运行；④全年运行较普通热泵热水器节能30％以上，较电热水器节能80％以上。

该产品为用户提供了超级节能和变频速热等多种模式选择，并且具有实时显示节省电量的功能，指导用户为节能，使产品更加人性化。

The Haier variable frequency air source heat-pump water

heater (product model: KF75/200-AE5, KF110/300-AE5)

first adopts the variable frequency energy saving technology

under all working condition of a heat-pump water heater with

optional modes.

The product has these features: the energy efficiency coefficient

COP under rated condition is as high as 5.0W/W, exceeding the

limited value 1.6W/W under nation standard, and 0.8W/W than

the grade 1 energy efficiency value (4.2W/W) under national

standard; the water heating time is shorter a half than ordinary

heat-pump water heater under ultra low temperature, but the

attenuation of heating capacity is smaller and COP higher; pure

heat-pump can run under the -15℃ environment; it can save

30% more energy than ordinary ones in whole year operation,

80% more than electrical water heater.

The product provides multi-mode options including ultra

energy-saving and variable rapid heating, and has the

function of displaying the saved electricity in real time, so

as to guide users’behaviour to save energy and make the

product more humanized.
