Regional cold supply system based on partition type energy stations

Abstract

The invention provides a regional cold supply system based on partition type energy stations. The regional cold supply system based on the partition type energy stations is mainly used for regional cold supply of a building group, and when each building energy consumption unit in the building group is provided with the partition type energy station, the summer regional cold supply requirement of the building group can be met. One or more partition type energy stations in the building group can provide chilled water for one or more other partition type energy stations through a centralized cold supply pipeline, the chilled water can further be obtained from one or more other partition type energy stations through the centralized cold supply pipeline, then regional cold supply of the building group is achieved through the partition type energy stations, instead of building a large-scale centralized energy station, the initial investment of a building group water chilling unit and supporting facilities thereof is reduced, the building flexibility of the energy station in a regional cooling mode is improved, and the equipment utilization rate and the energy efficiency are improved.

Description

technical field [0001] The invention belongs to an energy supply system, and in particular relates to a district cooling system based on district energy stations. Background technique [0002] The conventional building air-conditioning system is to set up a refrigeration station for a building energy-consuming unit, prepare air-conditioning chilled water, and then provide chilled water to the air-conditioning terminal system of the building energy-consuming unit through a circulating water pipeline system. For a building complex, That is, each building energy-consuming unit needs to be equipped with a refrigeration station to meet the air-conditioning needs of each building energy-consuming unit. The district cooling is to set up a centralized centralized energy station for a large area of ​​buildings, prepare air-conditioning chilled water, and then provide chilled water to the air-conditioning terminal system of each building energy unit through the circulating water pipel...

AI Technical Summary

Problems solved by technology

[0005] For the selection of cooling solutions for building groups, theoretically speaking, the above-mentioned district cooling mode has obvious investment and operational advantages compared with the scattered installation of chillers in each building’s energy-consuming units, but there are still many problems in practice. The main problems are: (1) Centralized energy stations deliver air-conditioning chilled water to building energy-consuming units, requiring new water supply and return pipes for transporting and distributing air-conditioning chilled water, which increases system investment; (2) Buildings with a large area often It is not built and put into use at the same time. Generally, it will take several years of development to have a corresponding scale. However, the corresponding construction scale and equipment investment need to be planned in the early stage of the district cooling mode, resulting in poor operating economy in the early stage of regional construction. Conducive to return on investment
