Abstract

The invention discloses an optimized design method for a mult-heat-source annular pipe network. The method includes building a multi-heat-source annular pipe network optimization model and adopting a genetic algorithm to solve the optimization model, to be precise, wherein the multi-heat-source annular pipe network optimization model takes annular equivalent cost of the pipe network as a target function and takes parameters like pipe diameter of the pipe network and lift of a circulating water pump as optimization variables, and optimization of the parameters of the pipe network is realized by adopting the genetic algorithm. By the optimized design method, accessibility of the designed multi-heat-source annular pipe network under different running conditions can be met, and the pipe network can be ensured to have high economic benefit.

Description

Technical field [0001] The invention relates to an optimized design method for a central heating pipe network, in particular to an optimized design method for a multi-heat source ring-shaped central heating pipe network to be built. Background technique [0002] The multi-heat-source ring-shaped pipe network can reasonably adjust the number and sequence of the heat source operation according to the changing law of the heat load in the heating season, so as to realize the efficient and energy-saving operation of the heating system. That is, under the condition of meeting the load requirements, priority is given to heat sources with high operating efficiency and low cost to shorten the operating time of low-efficiency and high-cost heat sources in the heating season, thereby reducing operating costs and achieving energy saving. According to the operating conditions of the heat source, the normal operating conditions of the multi-heat source looped pipe network can be divided into b...
