關於德國寶SH-09冷氣機,資料上寫了:
Voltage 220-240 V / 50 Hz Power (Cooling/Heating) 0.8 / 0.84 kW Electric Current (Cooling/Heating) 5.0 / 4.4 A Cooling Capacity in BTUⅱ 9,348 BTU/h Cooling Capacity in kWⅱ 2.74 kW
據我所知,計算用多少電是用voltage 乘以current 得出watt再計電費,但是上面power是0.8kW, cooling capacity又2.74kW,到底該用哪一個和它們有什麼分別??
