四、热网的优化设计热网的优化设计包括两个方面,一是走向优化(平面布置),二是比摩阻(管径的大小)和运行调节方式的优化。我们首先介绍热网平面布置优化。 4·1 热网平面布置的优化热网平面布置优化的方法很多,比较简单实用的是哈尔滨建筑工程学院供热研究室刘明生提出的最短路和最小树方法,该方法发表在区域供热1988年第一期,现在简述如下。 4·1·1 最短路原理最短路原理是多阶段决策中的一个问题。所谓多阶段决策是指这样的过程:它可以划分为若干个互相联系的阶段,每一阶段都要做出
IV. Optimization Design of Thermal Network The optimization design of the thermal network includes two aspects: one is to optimize (planar layout), and the other is optimization of the friction resistance (size of the pipe diameter) and operation adjustment method. We first introduce the layout optimization of the thermal network. 4.1. Optimization of thermal network layout optimization There are many methods for optimization of thermal network layout. The most short circuit and minimum tree method proposed by Liu Mingsheng, the heating research section of Harbin Institute of Civil Engineering and Architecture, is relatively simple and practical. This method is published in the district heating 1988. The first period of the year is as follows. 4·1·1 The shortest path principle The shortest path principle is a problem in multi-stage decision making. The so-called multi-stage decision-making refers to such a process: it can be divided into several interconnected stages, each stage must be made
