Regional energy supply system adopting centralized heating and partition type energy stations

Abstract

The invention provides a regional energy supply system adopting a centralized heating and partition type energy stations. The regional energy supply system adopting the centralized heating and partition type energy stations is mainly used for regional energy supply of a building group with centralized heating conditions, and when all building energy consumption units in the building group are provided with the partition type energy stations, the winter centralized heating requirement of the building group can be met, and the summer regional cooling 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 heating pipeline, and can further obtain the chilled water from one or more other partition type energy stations through the centralized heating pipeline; and regional energy supply of the building group is realized by a plurality of partition type energy stations instead of a large-scale centralized energy station, so that the initial investment of water chilling units and supporting facilities of the building group is reduced, and the equipment utilization rate and the energy utilization rate are increased.

Description

technical field [0001] The invention belongs to an energy supply system, and in particular relates to a regional energy supply system adopting centralized heating and partitioned 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 th...

AI Technical Summary

Problems solved by technology

[0006] 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, and it usually takes 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 model, resulting in poor operating economy in the early stage of regional construction. Conducive to return on investment
