Intelligent heat-supply system based on indoor temperature

Abstract

The invention relates to an intelligent heat-supply system based on an indoor temperature. The heat-supply system is composed of a boiler, a burner, a gas meter, a first electric control valve, a system electric control valve, a draught fan, indoor temperature transmitters, an intelligent control device, an oxygen content sensor, a nitrogen oxide sensor, a boiler outlet thermal flowmeter, a secondary thermal flowmeter, an outdoor temperature transmitter, a primary system water supply temperature transmitter, a plate-type heat exchanger, a second electric control valve, a waste heat recovery device, a waste heat recovery device inlet pressure transmitter, a waste heat recovery device outlet pressure transmitter, a boiler outlet pressure transmitter and a boiler inlet pressure transmitter. The intelligent control device is communicated with the other components of the heat-supply system through shielded cables. The intelligent heat-supply system based on the indoor temperature has the advantages that automatic control and adjustment of heating output loads can be achieved according to real-time heat using requirements and the heat using requirements of users are met on the premise of ensuring the heating quality, ensuring the safe and stable operation of the boiler and reducing the operating cost.

Description

technical field [0001] The invention relates to the field of heating, in particular to an intelligent heating system based on indoor temperature. Background technique [0002] At present, the existing technologies used in the heating intelligent system are: (1) climate compensation energy-saving technology, which automatically adjusts the output load of the boiler according to the outdoor temperature change. Since the outdoor temperature is an indirect parameter, it cannot directly reflect the heating effect of the user. At this time, the user's indoor temperature deviation is large, the heating comfort is poor, and the energy consumption is high. (2) Visual operation energy-saving technology. This technology uses indoor temperature as the basis for control. Operators can visually monitor the overall indoor temperature of users in public buildings or residential quarters. It only plays a display role and does not participate in system control. The temperature is unstable. ...

[0002] At present, the existing technologies used in the heating intelligent system are: (1) climate compensation energy-saving technology, which automatically adjusts the output load of the boiler according to the outdoor temperature change. Since the outdoor temperature is an indirect parameter, it cannot directly reflect the heating effect of the user. When the user's indoor temperature deviation is large, the heating comfort is poor and the energy consumption is high

(2) Visual operation energy-saving technology. This technology uses indoor temperature as the basis for control. Operators can visually monitor the overall indoor temperature of users in public buildings or residential quarters. It only plays a display role and does not participate in system control. unstable temperature

The defect of this patent application is that it can only rely on the data sensed by the human body to control the indoor temperature, which is uncertain.
