Time-of-use partitioned heat supply control system

Abstract

The invention relates to a time-of-use partitioned heat supply control system, which comprises a heat source host, supply / return water pipes, electric two-way valves, a time-of-use partitioned controller and control lines, wherein the supply / return water pipe is used for time-of-use partitioned buildings and a building with different functional partitions, the electric two-way valves are used for controlling on and off of water supply of the building or certain regions, and the time-of-use partitioned ontroller is used for setting a time-of-use partitioned scheme for the building or different functional partitions in the inner portion of the building. The time-of-use partitioned heat supply control system can set heat supply time according to respective different demands of the buildings in regions, and automatically turns on and off the electric two-way valve to guarantee reasonable heat supply demands. The time-of-use partitioned heat supply control system automatically opens a valve in a closed period of the valve through comparing a static water temperature and a set value of a monitoring pipeline to prevent pipelines from being frozen off, sets heat supply setting in weekends and holidays through an embedded perpetual calendar, can transmit turn-on time, state and water temperature of the valve and the like to the heat source host through communication, achieves heat supply of different buildings in regions and different functional partitions in the inner portions of the buildings according to demands, reduces consumption of primary energy in the regions in maximum, and reduces discharge of pollutant.

Description

technical field [0001] The invention relates to an energy-saving system for regional centralized heating, in particular to a time-sharing and district heating control system for coexistence of residential buildings and public buildings and its realization method. Background technique [0002] At present, the service objects of the district central heating system include not only residential buildings but also public buildings such as schools, office buildings, conference venues, and activity centers. Residential buildings are required to keep the indoor temperature basically constant for 24 hours due to the presence of people throughout the day, while office buildings only need to meet the comfort requirements of personnel during working hours and maintain antifreeze temperature during non-office hours. However, this mixed heating system is not specially designed for public buildings at the initial stage of design, and it performs continuous heating just like residential bu...
