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.
