Embodiment 1

[0023] Embodiment one: quickly realize the debugging method of this experimental device system hydraulic balance (see attached Figure 4 )

[0024] attached Figure 4 Described, the inventor quickly realizes the whole process of hydraulic balance debugging of the experimental device system. Pic 4-1 It shows 6 heating circuits. In the initial state without hydraulic balance debugging, the 6 heating circuits can be regarded as 6 central heating buildings in a certain community or 6 floors of a certain building in a certain community (buildings or The number of floors increases, and the debugging method is the same), these two different models can respectively represent the two hydraulic imbalance phenomena of horizontal imbalance and vertical imbalance in the heating pipe network.

[0025] In the whole debugging process, it is assumed that the heating area and heating load of each circuit are the same, respectively, the area 233 m 2 , building load 30 W, the temperature di...

Embodiment 3

[0034] Embodiment 3: A pressure difference control method and a flow control method to realize accurate heat supply on demand by users (see attached Image 6 )

[0035] attached Image 6 It describes that, on the basis of realizing the hydraulic balance of the experimental device system, when the heating demand of some users changes; or different buildings in the community, because of different locations, orientations, etc., cause the building load to change with time , through the pressure difference or flow control group, the adjustment process of the user's on-demand and precise heating can be realized.

[0036] Figure 6-1 to Figure 6-6 , which shows that through the differential pressure control group, the adjustment of precise heating supply according to the user's needs is realized. Same as Example 1, the 6 heating circuits are regarded as 6 floors in a building. When users on different floors change their heat demand and make independent adjustments, and need to red...

Abstract

The invention discloses an adjusting method based on a centralized heating system network and a data acquisition and application experimental device. The data acquisition and application experimentaldevice is called a device for short. A method developed and researched through the device is adopted to realize demanded and precise heat supply of a heat supply network. The implementation method comprises the following steps: 1, adopting the device to research and develop a new balance mode, and promoting the new balance mode in a heat pipeline network; 2, judging various system failures in theheat pipeline network through the equipment differential pressure and the flow value in the device; 3, realizing demanded and precise heat supply of the heat supply network through the differential pressure and flow control manner in the device; and 4, utilizing the device to simulate various hydraulic power working conditions in reality, and providing the design and improvement program of the heat supply network. The device comprises hydraulic equilibrium, differential pressure, flow control and automatic control. All equipment operating data is uploaded in real time, and a failure point is judged through data variation; an automatic control system can automatically adjust differential pressure and flow, realizes precise flow control in the device, supplies heat to the heat supply networkas demanded, and provides truthful data and theoretical basis.

Description

technical field [0001] The invention relates to the technical field related to hydraulic balance and automatic control of a central heating pipe network, and specifically relates to a hydraulic balance debugging method of a central heating pipe network, a pressure difference control method, a flow control method, and the like. Background technique [0002] At present, China is promoting the transformation and upgrading of various industries through the use of new-generation information technologies such as "Internet +", Internet of Things, big data, and artificial intelligence from the height of national strategy. "Smart" has generally become the key to describe the characteristics of such transformation and upgrading word. At present, the concept of "smart heating" has been formally proposed and has become the focus of attention of China's heating industry. However, the hydraulic imbalance of urban central heating pipe network is still the biggest pain point faced by the h...
