Integrated heat-supply and energy-saving system

Abstract

The invention relates to an integrated heat-supply and energy-saving system comprising a heat source, a heat-supply pipe network, a heat-supply control system, a pipe network balancing system and a waste heat recovering system, wherein the heat source is used for generating heat; the heat-supply control system is used for detecting indoor temperature to provide temperature parameters for weather compensation, monitoring the indoor temperature of users on line in real time and regulating the on/off of a relevant boiler, a circulating pump, an air conditioner, a ground source heat pump and a valve according to outdoor temperature and the indoor temperature of the users to control the heat-supply quantities of the heat users with different heat-supply properties, thereby realizing the automatic switching of anti-freezing running and heat supply; the pipe network balancing system is used for controlling each branch pipe to run by the set flow according to the branch pipe flows preset in one step, thereby improving the water pressure of the pipe network; and the waste heat recovering system is used for recovering energy for secondary application to reduce the heat loss of the heat-supply system. The integrated heat-supply and energy-saving system can automatically and intelligently control heat supply according to the heat-supply properties of the heat users, improve heat-supply quality, fully recycle waste heat at the tail end of the pipe network and carry out real-time on-line monitoring to the temperature of the pipe network.

Description

technical field [0001] The invention belongs to the technical field of thermal energy utilization, and relates to a heating system, in particular to an integrated heating and energy-saving system capable of significantly improving thermal efficiency and saving energy and reducing consumption. Background technique [0002] In order to purify the air and protect the environment, many cities use central heating systems to provide heat for offices and residential areas in winter, which prevents environmental pollution from many small boilers and has achieved good results.
