摘要(Abstract):

空调系统的负荷侧与源侧的进出水设计温差是5℃,然而,从节能的角度看,传统的5℃温差并非对于所有的系统都是使得系统运行费用及初投资最低的最经济温差。本文通过对某间接式污水源热泵机组在非标况下的试验研究,对末端机组、污水-中介水换热器及水泵的运行分析,得出系统两端的最经济的温差,使得系统运行费用与初投资最低。
The designed temperature difference between inlet water and outlet water of the load side and source side in an air conditioning system is 5℃.However,from the point of energy saving,the traditional 5℃ is not most economical temperature difference to all the systems,making the lowest operating cost and initial cost.The paper obtains the most economical temperature difference between the sides of the system by conducting experimental researches under non-standard conditions and analyzing the operation of the FCU,heat exchanger and water pump,making the lowest operating cost and initial cost.
