Dynamic balance dual-source time on-off area heat metering system and method

Abstract

The invention relates to a dynamic balance dual-source time on-off area heat metering system and method. The system comprises a client and a management terminal, wherein the client comprises an adjustable flow balance valve mounted on a heat supply pipeline, an electric heat executor for controlling the opening and closing of the adjustable flow balance valve, an IC (integrated circuit) card typeheat metering temperature controller connected with the electric heat executor to control the temperature, and an user recharging IC card for recharging the IC card type heat metering temperature controller; the management terminal comprises a recharging machine and a computer. The system provided by the invention can guarantee the same final heating effect for all households on the basis of guaranteeing the water balance; the flow rate of each household is preset so that the heat metering can be performed in a way that the user can consume heat according to the time after prepaying.

Description

technical field [0001] The invention relates to a heat metering system, in particular to a dynamic balance dual-source time on-off area heat metering system, and also relates to a dynamic balance 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 temperature diff...

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
