摘　　要：目前在用户侧加装智能平衡阀可有效解决二级管网失调问题,但由于用户的物理位置不同、邻室存在未供暖用户等因素影响,导致存在智能阀调控后供暖用户室温不一致的现象,无法满足户间平衡,因此需对热用户精细化分类进行调控。本文提出一种融合房间物性系数等多因素的热用户分类辨识方法,采用此方法对濮阳市某小区热用户辨识分类为11类。基于辨识出的用户类型进行了回水温度相对一致性平衡调控,调控后发现所有用户的室温接近目标室温,室温不均匀系数N_(c)由调控前的0.061降至0.022,很好的改善了用户的热力失调问题,实现了用户侧的户间平衡。At present,the installation of an intelligent balancing valve on the user side can effectively solve the problem of secondary pipe network imbalance.However,due to the influence of different physical locations of users and the existence of unheated users in adjacent rooms,the temperature of heating users is inconsistent in different rooms after intelligent valve regulation,failing to realize the balance between rooms.Therefore,it is necessary to regulate and control the refined classification of heat users.This paper proposed a classification and identification method for heat users that integrates multiple factors such as room physical property coefficients.This method was used to identify and classify heat users into 11 categories in a community in Puyang City.Based on the identified user types,the relative consistency balance control of the return water temperature was made.After the control,it was found that the room temperature of all users was close to the target room temperature,and the room temperature non-uniformity coefficient Nc dropped from 0.061 to 0.022,significantly improving the thermal power imbalance of the users,and realizing the balance between households on the user side.
