【Abstract】 This paper states the actual measurement of the overall coefficient of heat transfer of water coolers with a little fouling in refrigerating systems.Combined with certain document data,the drop of the coefficient caused by the water fouling is researched.The increase in pressure work is analyzed and calculated,which is caused by the drop of the coefficient.The consumption is increased by about 7%.According to the yearbooks the power consumption is calculated from the macro point of view and reaches more than 4 billion dollars.It is suggested that the on line self cleaning fouling technology should be used widely.更多还原
