Detailed ways

[0070] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0071] The present invention provides a new type of thermal inlet valve position control method, the method is mainly aimed at Figure 6 The central heating system of a certain campus in Tianjin shown, the heating area of ​​the energy center is 240538m 2 , 4 gas-fired boilers directly supply 19 independent buildings, including scientific research office buildings, student dormitories, teaching buildings, canteens and many other types of users.

[0072] The heating system will implement intelligent transformation in the heating season of 2019-2020. The 28 thermal inlets under its jurisdiction are equipped with electric balance integrated valves, and the communication modules connected to the monitoring platform are installed a...

Abstract

The invention relates to a novel heating power inlet valve position regulation and control method which directly starts from the angle of controllable parameters, determines target loads of different heating power inlets at the future moment according to a peripheral module on the basis of energy center water supply temperature and flow constraint conditions, and determines valve positions of different inlets at the future moment. By the adoption of the method, the situation of over-supply of a heating power inlet of the tail end can be effectively avoided, the one-step adjusting mode of the tail end is avoided, time-division, temperature-division and partition on-demand heating is achieved as far as possible in combination with specific scenes, the heat demand of a user is met, and meanwhile energy conservation and emission reduction are remarkably achieved.

Description

technical field [0001] The invention belongs to the technical field of central heating system operation adjustment, and in particular relates to a novel heat inlet valve position adjustment method. Background technique [0002] Central heating is the most common form of heating in northern my country. "Heating on demand" is the basic path to ensure users' heat demand while achieving significant energy saving and emission reduction. Due to the large thermal inertia of the system, the thermal inertia of the building, and the time-varying nature of the user's heat consumption mode in central heating, the transient adjustment response capability of the system is limited, and there are different degrees of mismatch between supply and demand and energy waste in the actual heating process. . [0003] According to statistics, the heating area in northern my country exceeds 20 billion square meters, and the current average energy consumption is about 15kg standard coal per square m...
