功率为8000BTU的窗式空调.
BTU的数字代表的是国外制冷量的一个标识.
British Thermal Unit ,英国热量单位 1BTU约等于251.9958卡路里(calorie)/0.293瓦特时(watt-hour)/1.055千焦(killojoule) 1Btu就是将1磅水的温度升高1华氏度所需要的热量 Btu是英热单位(英制),Btu/h就是“英热单位每小时”,由于 1(英热单位) = 1055.056(焦),而 1瓦特 = 1焦/秒.所以 1(英热单位每秒) = 1055.056(瓦特),把秒换为小时就是:1英热单位每小时 = 1055.05585262(瓦特)/3600 = 0.293(瓦).所以一台 (BTU/H) 为8000的空调功率为 8000*0.293 = 2.344(千瓦).
