Problems solved by technology

Although this kind of system can solve the problems existing in the double-pipe reverse heating system, the hydraulic flow of the heating circuit is not good. At the same time, in order to ensure its working effect, the water supply pump needs to have a larger working power.
[0003] The above-mentioned double-pipe reverse heating system and double-pipe simultaneous heating system can realize the household charging of heating users according to the actual heat consumption, but this requires the addition of separate household metering facilities for each user
At the same time, when the heating monitoring and control operations of the above two systems are carried out, the user needs to manually check the meter, charge and control, and it is impossible to realize the operation of centralized heating monitoring and corresponding heating control. It brings inconvenience, and the heat network management department cannot carry out long-distance monitoring, let alone carry out heat scheduling on the heat supply network according to the actual situation of heat supply

Abstract

The present invention relates to central heating supply and separated metering system. The double-pipe heat distribution separating management network system for central heating includes heating supply main pipe, return pipe, heating supply branch pipes in different stories, return branch pipes, and the heating supply loads in different stories connected to return branch pipes. It features the remote flowmeter and main inflow water temperature sensor in the main heating supply pipe, and / or intelligent electric two-way flow regulating stop valve and main return temperature sensor in the main return pipe, main acquisition controller, and real-time monitoring main flowmeter connected to the output of the main acquisition controller.

Description

Technical field: [0001] The present invention mainly relates to a household metering system for central heating, in particular to a household metering system for building groups or high-rise buildings, or to the transformation of existing heating systems and a method for metering and charging such systems. Background technique: [0002] The double-pipe plumbing heating system in the prior art generally consists of two systems, 1 is a double-pipe reverse heating system, this system is to set up a horizontal heating main pipe and a return water main pipe under the heating area. The unit is installed on the vertical heat supply pipe and the vertical water return pipe connected by the horizontal heat supply main pipe and the horizontal return water main pipe. The floor pipeline is used to communicate with the vertical heat supply pipe and the vertical return water pipe between each floor, and each heating load is connected. In this kind of system, the users on the lower floors c...
