Abstract

The invention discloses a centralized regional energy supply method, belonging to the field of regional energy supply, including regional energy stations, centralized industrial areas and commercial residential areas; laying a public medium and low pressure steam pipe network for the centralized industrial areas and commercial residential areas, According to the demand of commercial residential areas, the quality of steam is slightly lower than the energy consumption characteristics of centralized industrial areas, so that centralized industrial areas are located near the regional energy station, and commercial residential areas are located at the far end of the regional energy station, realizing resource optimization of the regional energy system. Configuration; use saturated steam to drive the lithium bromide refrigeration unit on the user side to supply chilled water to the surrounding buildings. The invention reduces the construction and maintenance costs of laying independent cooling and heating energy supply pipe networks, reduces the loss of cooling capacity caused by long-distance transportation of frozen water, and reduces the user's dependence on electric refrigeration during the peak period of air-conditioning use in summer. The heating and heat storage system balances the energy demand in the district energy supply system, and is a centralized district energy supply method that cuts peaks and fills valleys.

Description

technical field [0001] The invention relates to the area energy supply field, in particular to a centralized area energy supply method, and is especially suitable for the planning and design of an area energy supply system. Background technique [0002] The summer in southern my country is hot and hot. In order to meet the electricity demand of residents and industries, the country has continuously strengthened the power construction, and the installed capacity of power generation has been increasing year by year. However, during the period of peak power demand, traditional thermal power, especially the gas-steam combined cycle unit with fast response to variable load, often faces low-load operation or is forced to shut down, resulting in shrinking corporate profits and even facing losses, relying on government subsidies to maintain normal operations status. [0003] Centralized district heating has been very popular in the north of my country, and the heating in the south ...
