Static balance type dual-source type time on/off area heat metering system and method

Abstract

The invention relates to a static balance type dual-source type time on/off area heat metering system and method. The system comprises a client and a management end, wherein the client comprises a static balance on/off control valve arranged on a heat supply pipeline, an electric heating executor for controlling the static balance on/off control valve to open and close, an IC (Integrated Circuit)card type heat metering temperature controller and a user charging IC card, wherein the IC card type heat metering temperature controller is connected with the electric heating executor and is used for realizing temperature control; the user charging IC card is used for charging the IC card type heat metering temperature controller; and the management end comprises a charger and a computer. According to the static balance type dual-source type time on/off area heat metering system and method disclosed by the invention, on the basis of ensuring the static hydraulic balance, the hot water flow of each user is adjusted in advance according to the heat load of the user at the tail end so as to ensure that each user can acquire ideal heating temperature. The heat user prepays in a heat supply unit for purchasing the heating time; and the heat is generated by consuming the heating time.

Description

technical field [0001] The invention relates to a heat metering system, in particular to a static balance type dual-source time on-off area heat metering system, and also relates to a static balance type dual-source time on-off area heat metering method. Background technique [0002] Central heating is the most basic heating method in my country at present, and heat metering is a problem that must be faced. The traditional metering method only charges according to the area, which cannot reflect the rationality and fairness of the charges. At the same time, the unreasonable heating charging system charged by area cannot mobilize people's awareness of heating and energy saving, resulting in a lot of waste of resources. According to the experience of developed countries, the implementation of reasonable measurement methods can save energy by 20-30%. [0003] At present, the heat measurement methods tried in some areas include the heat meter measurement method and the temperat...

Problems solved by technology

[0004] The heat meter measurement method is mainly the method of mechanical heat meter or ultrasonic heat meter plus temperature control valve, which is widely used in Tianjin. This method has been tested for a long time and is relatively stable. The mechanical heat meter is blocked; the measurement accuracy of the ultrasonic heat meter itself is not high, and the qualified rate of the heat meter in China is only 15%; the measurement accuracy will decrease after long-term use; the insulation between the floors of Chinese buildings is not done, and this method cannot solve the heat conduction between floors Problem: The heat in the public area cannot be apportioned directly, and this kind of measurement method is not welcomed by the heating company

This method is widely used in Northeast China, Shanxi and other regions. It solves the problems of low-quality heat meters, easy blockage of pipes, and apportionment of public areas. The flow area control valve is prone to water imbalance
