Embodiment 1

[0067] This embodiment provides a route planning method for district cooling system pipe network, see figure 1 shown, including:

[0068] In step S100, the planning system establishes a directed graph of pipe network route planning according to the design diagram of the district cooling system, wherein the directed graph of pipe network route planning includes multiple vertices and multiple edges, and each edge has a weight value. A directed graph is a basic graph in graph theory. It consists of multiple vertices and edges connecting multiple vertices. Each edge has a direction. In this embodiment, the direction of each edge in the directed graph is planned for the pipeline network route It should be determined according to the flow direction of the cooling medium of the district cooling system.

[0069] Specifically, the design drawing of the district cooling system in step S100 is an engineering drawing drawn during the design of the district cooling system, which should in...

Abstract

The invention relates to the technical field of air conditioners and discloses a district cooling system pipe network path planning method and system. The method comprises the steps that a planning system establishes a pipe network path planning directed graph according to a district cooling system design drawing, wherein the pipe network path planning directed graph comprises multiple vertexes and multiple sides and each side has a weight value; for two selected vertexes, the shortest path between the two vertexes is determined according to connection relations between the two selected vertexes, other vertexes between the two selected vertexes and the sides and weight values of all the sides; according to the shortest path, a district cooling system pipe network path is determined. The district cooling system pipe network path planning method solves the problems that in the prior art, a pipe network is overlong because the pipe network of a district cooling system is designed according to experience of designers, and therefore cold energy loss of the district cooling system is too much.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method and system for planning a pipe network route of a district cooling system. Background technique [0002] District cooling is a regional centralized cooling method that prepares air-conditioning chilled water by setting up a centralized refrigeration station, and then provides air-conditioning chilled water to nearby buildings through the pipeline network. This cooling method not only improves the efficiency of the air conditioning system, but also realizes the cascade utilization of energy, thereby reducing environmental pollution, improving the thermal economy of the system, and making the air conditioning cooling meet the requirements of scale, specialization, industrialization and market requirements. [0003] However, district cooling also has the problems of low energy supply efficiency and poor economy caused by long construction period, large investment,...
