Abstract

The invention discloses a method for controlling the balance of vertical and horizontal imbalances of a secondary network. By setting the temperature sensor, the water supply temperature, return water temperature and indoor temperature are collected; the dynamic flow balance valve is set on the heating pipeline of each user; each unit is respectively equipped with a collection concentrator, which is used to collect the water supply temperature and return water temperature of each household and indoor temperature, the collection concentrator communicates with the remote control center. During regulation, according to the indoor target temperature and outdoor temperature, as well as the current indoor temperature, supply water temperature and return water temperature, the target value of the average temperature of the user's supply and return water is calculated and sent to the dynamic flow balance valve. The average temperature of the water level controls the increase and decrease of the flow rate until the stabilized indoor temperature reaches the indoor target temperature. The invention solves the problem that it is difficult to adjust the vertical and horizontal imbalances in the secondary network system at the same time, and the problem that the indoor temperature of each household is unbalanced leads to large measurement errors.

Description

technical field [0001] The invention relates to a control method for a heating secondary network, and specifically designs a balance control method for the vertical and horizontal imbalance of the secondary network. Background technique [0002] According to statistical data, the area of ​​the central heating system in the north of my country currently exceeds 12 billion square meters. In the central heating system, cogeneration is responsible for 50% of the heat source supply on average, while coal-fired gas boilers account for 50% of the heat source. Every year, about 500 to 800 million square meters of newly added heating area in northern my country leads to a serious shortage of heat sources in most cities. On the one hand, the supply is seriously insufficient, on the other hand, energy waste is also serious. [0003] In the case of unbalanced water conservancy conditions in the secondary network, some buildings, especially the near-end residents, have high indoor temp...
