海爾變頻空氣能熱水器(產品型號KF75/200-AE5、KF110/300-AE5)首次應用了“面向模式可選的熱泵熱水器全工況變頻控制節能技術”。
產品具有以下特點：①額定工況最大能效系數COP達到5.0W/W超出國標限定值1.6W/W且高出國標一級能效值（4.2W/W）水平0.8W/W；②超低溫環境-7℃制熱水時間較普通熱泵熱水器縮短一半，制熱量衰減小，COP高；③純熱泵最低可在-15℃環境運行；④全年運行較普通熱泵熱水器節能30％以上，較電熱水器節能80％以上。
該產品為用戶提供了超級節能和變頻速熱等多種模式選擇，并且具有實時顯示節省電量的功能，指導用戶為節能，使產品更加人性化。
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.
