摘要:: 利用换热网络进出口温度之间固有的线性性质,在理论分析的基础上,提出温度传递系数的概念,对换热网络温度波动的影响进行定量分析,从而确定温度波动在系统中的传递性质;计算温度波动在系统中产生的影响,进而获得需要改进换热网络的数据和信息.利用换热网络温度传递系数法计算的实例结果对于指导实际生产具有积极意义.通过温度传递系数可以较为明确地看出哪些影响因素占据主导地位、哪些影响因素较为次要,以方便工程技术人员及时、准确地测控各个影响因素.

Abstract:: Using the inherent linear properties between the inlet and outlet temperatures of the heat exchange network, the concept of temperature transfer coefficient is proposed on the basis of theoretical analysis, and the influence of temperature fluctuation of heat exchange network is quantitatively analyzed, so as to determine the transfer property of temperature fluctuation in the system. Calculate the effects of temperature fluctuations in the system to obtain data and information that need to be improved in the heat exchange network. The example results calculated by the temperature transfer coefficient method of heat exchange network are of positive significance for guiding actual production. Through the temperature transfer coefficient, it can be clearly seen which influencing factors are dominant and which influencing factors are secondary, so as to facilitate engineers and technicians to measure and control each influencing factor in a timely and accurate manner.
