摘　　要：建立了冷却水系统制冷机、水泵及冷却塔数学模型,研究了冷却水泵和冷却塔风机变频对冷却水系统能耗的影响。结果表明:在冷却水泵调整至最大节能量工况时,冷却水泵变频对系统能耗的降低有积极意义;冷却塔风机变频并不能有效降低制冷系统能耗。Establishes the mathematical models of refrigerator,pump and cooling tower in cooling water systems,and studies the effects of the frequency conversion of cooling water pump and cooling tower fan on the energy consumption of cooling water system.The results show that when the cooling water pump is adjusted to the working point of maximum energy saving,the frequency conversion of cooling water pump is of positive significance to reduce the energy consumption of the refrigeration system,and the frequency conversion of cooling tower fan can not effectively reduce the energy consumption of the refrigeration system.
