Heat-supply pipe network self-adaptive flow balancing method and device

Abstract

The invention discloses a heat-supply pipe network self-adaptive flow balancing method and a heat-supply pipe network self-adaptive flow balancing device. The method comprises the following steps: firstly, acquiring the flow and the pressure at a valve, an indoor temperature and an outdoor temperature; secondly, comparing measured data with set values; and thirdly, adjusting the opening degree ofthe valve according to whether the measured data exceed the range of the set values, and balancing the flow in a system by adjusting the opening degree of the valve, so that the purpose of balancing the flow is achieved. The device comprises flowmeters, pressure sensors and thermometers which are mounted beside the valve; the flowmeters, the pressure sensors and the thermometers are all connectedwith a data acquisition module; the data acquisition module communicates with a data processing module; the data processing module is also connected with an indoor thermometer and an outdoor thermometer; and the data processing module is connected with an executing mechanism which controls the opening degree of the valve. The heat-supply pipe network self-adaptive flow balancing method and the heat-supply pipe network self-adaptive flow balancing device can adjust automatically in real time to balance the flow in a pipe network; and the timeliness is good. The professional requirement on working personnel of a heating power company is reduced.

Description

technical field [0001] The invention relates to the field of heat pipe network flow balance, in particular to a heat pipe network self-adaptive flow balance method and device. Background technique [0002] With the continuous improvement of my country's economic level, the central heating system is also developing. In the heating system, how to ensure that the heating load changes regularly with the outdoor temperature and how to ensure the flow balance in the pipe network is the purpose of the heat pipe network system. [0003] In the traditional heating mode, the valves are manually adjusted by experienced workers or combined with a remote control system to control the opening and closing of the valves. These methods require experienced professionals to implement them. If there is a problem in the pipe network, the user needs to report it to find the problem. Therefore, the existing method requires high professionalism and experience, and the timeliness is too poor. Co...
