Intelligent heat supply dynamic hydraulic balance control method

Abstract

The invention discloses an intelligent heat supply dynamic hydraulic balance control method. The method comprises the steps that a circulating pump in a heating station is set to be in a constant pressure difference operation mode; the number of users with heating in each unit of a building is counted, and the actual total heating area of each unit is calculated; a flow coefficient of a set unit area is selected; and the flow coefficient of the unit area and the actual total heating area of each unit are input into an upper computer, and the upper computer calculates the total flow needed by each unit. The method has the advantages that the heat supply and energy saving effects are good, the phenomenon of uneven heat supply can be avoided, the heat supply quality is improved, the operation cost is saved, and the like.

Description

technical field [0001] The invention relates to the technical field of heating pipe network balance adjustment, in particular to an intelligent heating dynamic hydraulic balance control method. Background technique [0002] Most of the heating in northern cities in my country adopts centralized heating. With the improvement of economic level, the distribution area of ​​heating pipe network is getting larger and larger, and the number of heat users is also increasing sharply. The heating temperature of different areas or floors in the network varies greatly, the room temperature of the near-end users is high, and the room temperature of the far-end users is low. Even if the heat pump is overloaded, it will not help, the energy consumption is high, the operating cost is high, and the operating efficiency of the heating system is reduced. . [0003] In order to solve the above problems, in the prior art, there is a method of improving the heating effect by using a dynamic balanc...

Problems solved by technology

[0004] The shortcomings of this structure and control method are as follows: first, it is necessary to place wireless remote temperature collectors in the homes of several users in each unit, and the number of heat users is large, which greatly increases the heating cost; second, the return water temperature of the unit The value and the room temperature value of the unit user need to be fed back to the server in real time. After the server passes the calculation, it will issue the valve opening change amount command to the automatic control unit of the balance valve. The automatic control unit of the balance valve will then control the mechanical transmission flow control unit to adjust the valve. Opening, in the process of adjusting the opening of the balance valve, the server must always participate. The heating pipe network has a large distribution area, and the server calculates and processes a lot of data, which takes a long time. There is a delay in data processing and transmission, and the server has high computing performance requirements. The thermal system is also expensive to run
