Description

technical field [0001] The invention relates to the technical field of heat supply test simulation, in particular to a digital simulation system and method for heat supply temperature curve and hydraulic balance adjustment. Background technique [0002] In recent years, with the improvement of environmental protection requirements, clean heating in winter in northern regions has gradually developed. Facing new things and new formats such as comprehensive energy heating, it is necessary for the staff involved to master its operating principles and processes as soon as possible and systematically. process, accumulate experience, share with each other, and make progress together. Therefore, in clean energy heating, in order to meet energy saving and consumption reduction while ensuring the heating effect, the heating operation curve and the hydraulic balance adjustment among users under the closed system are applied in the actual heating operation. [0003] At present, the set...

AI Technical Summary

Problems solved by technology

[0003] At present, the setting of the heating operation curve is based on empirical values. It has not been tested and tested in actual operation. It has not formed an iteration of data optimization and cannot accurately achieve the same heating effect in different environments. The actual heating There will still be situations where the indoor heating temperature is higher when the outdoor temperature is high or the weather is good, and the indoor heating temperature is lower when the outdoor temperature is low or the weather is bad; at the same time, there is no one for the hydraulic balance of the heating system. The platform that can be simulated and operated cannot realize and digitize the hydraulic balance. The actual adjustment process lacks operability and reproducibility. There are still cases where the middle user opens the window to dissipate heat, and the temperature of the side household and the top floor user does not meet the standard. In order to improve this situation For the problems of no energy saving and poor heating experience, it is necessary to provide a simulation system to simulate it, so as to better determine the heating curve and adjust the hydraulic balance
