Method for reducing transmission and distribution energy consumption of regional central heat supply network

Abstract

The invention discloses a method for reducing transmission and distribution energy consumption of a regional central heat supply network. The method comprises the steps of establishing a building heating entry jet flow mixing device of a building according to all of heat supply building heating entry within a heat supply range of a heat supply system, adjusting the opening degree of an electric valve of the building heating entry jet flow mixing device and the jet mixing ratio of the water jet flow mixing device, adjusting a transmission and distribution water pump configured for the heat supply network according to building heating mass requirement so as to adjust transmission and distribution flow of the heat supply network and achieve adjustment of all building heating entry positions. Under the situation that the flow of the heat supply system in the building is constant, the flows of the building heating entries connected with the heat supply network is reduced to reduce the transmission and distribution energy consumption of the heat supply network, electricity consumption of the transmission and distribution water pump, improve the temperature difference of supply water and return water and the ratio of the transmission and distribution flows of the building heating entries connected with the heat supply network to the flow of the building heat supply system, improve the adjustability and stability of hydraulic power and heating power of the building heat supply system, save device and maintain cost.

Description

technical field [0001] The invention relates to the technical field of energy saving and efficiency enhancement of central heating systems, in particular to a method for reducing transmission and distribution energy consumption of regional central heating networks. Background technique [0002] At present, the total building heating area in northern my country is about 9 billion square meters, of which nearly 75% of the heating area adopts centralized heating. According to the process of heating heat from conversion, preparation, transportation, and use, the central heating system includes heat sources (cogeneration, boiler room), primary heating network, multiple heat stations, and secondary heating network to reach many buildings. The thermal entrance of the building enters the indoor heating system, etc. There is a large difference between the specification parameters selected in the design stage of the heat sources in the transmission and distribution system in the cent...
