Variable flow and household metering centralized heating system and hydraulic balance regulating method

The invention discloses a variable flow and household metering centralized heating system and a hydraulic balance regulating method. The system comprises household metering modules, a water supply temperature measuring module, a water returning temperature measuring module and a heat supply network monitoring and controlling management platform. The household metering modules are arranged at the positions of users, and the heat supply network monitoring and controlling management platform is in communication connection with the household metering modules and a total circulating pump and collects the water supply temperature and the water returning temperature in pipe network systems through the water supply temperature measuring module and the water returning temperature measuring module; and a frequency changer is arranged on the total circulating pump. The water quantity needs of the users are met, and on the premise that the heat comfort requirement of the users is met, the flow is adjusted according to needs, and energy consumption is reduced; and the cost is saved, the reliability and the stability are higher, and the system is more suitable for long-term utilization.
