运用基本传热原理建立了系统模型和传热模型,进行了传热理论计算,分析了采用不同厚度绝热层的管道流体温升及冷量损失。运用经济技术方法分析了输配系统初投资和运行管理费用。对比了采用分用二级水泵、合用二级水泵两种方案的优劣。结果表明,合泵方案较分泵方案在初投资和运行费用上均有优势。
The system model and heat transfer model are established by using the principle of heat transfer. The theoretical calculation of heat transfer is carried out. The temperature rise and the loss of cooling capacity of pipeline with different thickness of heat insulation layer are analyzed. Using economic and technical methods to analyze the initial investment and operation and management costs of the transmission and distribution system. Contrast the use of sub-two pumps, two pumps combined two advantages and disadvantages. The results show that, compared with the pump program pump solution in the initial investment and operating costs have advantages.
