科福乐公司的大型工业吊扇主要用于大面积、高屋顶的室内场所，如开放式办公楼、购物中心、厂房及仓库等，可以起到降温或调解暖空气的作用。

　　在降温方面，如使用大型工业吊扇，则大型室内场所的空调温度设定可比通常设高5至10华氏度，可达到节能目的。

　　在调节暖空气方面，由于该类场所通常净空气比较高，空间上下温差比较大。在离地面1米多高的地方，即人活动的高度，如果温度是70华氏度，在10米高空左右温度就达到96华氏度。使用该吊扇可以将高空的暖空气吹向人活动的低处，这样同样可以达到大型工业风扇的节能目的。

　　Section Lok Fu company's energy-saving ceiling fan is mainly used for large area, high roof interior space, such as the open office buildings, shopping centres, factories and warehouses, can play a cool or warm air role mediation.In cooling, such as the use of the ceiling fan, large indoor air temperature setting is usually set high and 5 to 10 degrees Fahrenheit, can achieve the purpose of saving energy.In the regulation of warm air, the place usually clean air is relatively high, the space under the relatively large temperature difference. From the ground 1 meters high places, namely human activities, if the temperature is 70 degrees Fahrenheit, at an altitude of 10 metres or so the temperature reached 96 degrees fahrenheit. The use of the ceiling fan can be above the warm air blowing of low activity, it can also achieve the purpose of saving energy
