Embodiment Construction

[0019] The composition of the system includes: heat source circulating pump 1, electric switch valve 2 is set at the entrance of heat user 3 (single building or thermal area with the same function), water supply and return temperature sensors 4, 5 and external temperature sensor 6, and also includes the core unit Intelligent controller 7.

[0020] The system runs as follows:

[0021] First, the self-heating source is supplied with hot water from a circulating pump controlled by frequency conversion, and the hot water is pushed out along the water supply pipe. The electric valve 2 is open. The intelligent controller 7 judges the current state according to the preset heating and antifreeze time. During the heating period, the intelligent controller 7 according to the return water temperature T provided by the return water temperature collector 5 in real time h Calculate to determine whether it is less than the set value of the return water temperature, if the return water temperatur...

Abstract

The invention relates to an energy conservation controlling system for the time-sharing and large temperature difference heat supplying, which belongs to the field of the building heat supplying system controlling technology. The energy conservation controlling system comprises a system combined by a hardware configuration and a software module. An electrical switch valve is arranged at the inlet part of the heat consumer, namely the single building or the hot area with the identical function, the temperature outside the monitoring room is Tw, the temperatures of the supply and return water are respective Tg and Th, and an intelligent controller IC is arranged at the nearest part. The intellectualized function is realized mainly through the analyzing and computation of the software. The energy conservation controlling system has the advantages that the energy conservation effect is obvious, the heat supplying security is good, the adjustability is strong, and the energy conservation controlling system is suitable for the new-building system and the reconstruction of the old system.

Description

Technical field [0001] The invention belongs to the technical field of building heating system control. Mainly aimed at the traditional heating mode, especially for the mixed-network heating places such as universities, enterprises and institutions, large factories, because different heat users do not need heat at different times, but cannot adjust the situation, and large The heat supply with small flow rate and low temperature difference is currently inefficient, and a time-sharing large temperature difference heating energy-saving system is proposed. By providing specific points of application, the huge energy-saving space under current operating conditions is transformed into a significant energy-saving reality. Including the combination of hardware configuration and software modules to form a system. Background technique [0002] The prior art treats buildings with different heating characteristics that are mixed in the same heating area, and uniformly implements continuous ...
