Dynamic hydraulic balance adjusting method for centralized heating system

Abstract

The invention provides a dynamic hydraulic balance adjusting method for a centralized heating system. The method comprises the steps that operation data of end users of the centralized heating system are obtained, indoor environment data of the end users are obtained, outdoor environment data are obtained, and water supply temperature data of a main pipeline of the centralized heating pipe network system are obtained; a target indoor environment state of the end users of the centralized heating system are set; control parameter curves of the centralized heating system are calculated according to the target indoor environment state of the end users and the water supply temperature data of the main pipeline, and the control parameter curves comprise at least one of an electric two-way valve control parameter curve of all the end users and a water supply-return pressure difference control parameter curve of the centralized heating main pipeline; and the centralized heating system is controlled to operate according to the control parameter curves. According to the adjusting method, no sensor or dynamic hydraulic balancing valve or other equipment needs to be arranged; dynamic hydraulic balance of the centralized heating system is achieved through dynamic control over electric two-way valves of the end users, the requirement for indoor comfort is met, the energy consumption of the centralized heating system is reduced, and the implementation cost is low.

Description

technical field [0001] The invention relates to the field of central heating system control, in particular to a method for adjusting the dynamic hydraulic balance of the central heating system. Background technique [0002] With the further improvement of energy-saving requirements, room temperature compliance requirements and refined heating management requirements, the demand for scientific and rational adjustment of the hydraulic balance of the heating network is becoming stronger and stronger. The user's indoor temperature reaching 18±2℃ is the national standard for heating work , and due to the limitation of the heating principle and the current pipe network layout, the inconsistency between the actual flow of each user in the heating system and the design required flow still exists, and the phenomenon of near-end overheating and far-end overcooling caused by hydraulic imbalance If it cannot be effectively improved, it will not only reduce the efficiency of the heating ...
