A linkage system and linkage method of heat inlet balance and heat exchange station of the second network

Abstract

The invention belongs to the technical field of HVAC, and relates to a linkage system and method for the heat inlet balance of the second network and the heat exchange station. The heat inlet balance subsystem and the heat exchange station subsystem cooperate with each other through a host computer. The principle of active, passive and non-moving among all links of the thermal system realizes the cooperation between the heat exchange station and the heat inlet; the centralized command of the upper computer, the active distributed adjustment of the heat inlet, and the heat exchange station passively meet the operation requirements of the heat inlet Under operating conditions, the fully automatic heat inlet balance can be realized under the condition of the minimum flow rate of the circulation pump of the heat exchange station. This patent provides an automatic linkage method with the heat exchange station in the process of realizing heat inlet balance, and realizes the circulation of the heat exchange station. The method by which the pump operates at minimum flow.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air conditioning, and in particular relates to a linkage system and linkage method of a heat inlet balance of a second network and a heat exchange station. Background technique [0002] The hydraulic imbalance of the secondary pipe network of the central heating system is a long-term operational problem that cannot be solved. The hydraulic imbalance causes the temperature in the heat users' homes to be uneven. Heat and power consumption have increased significantly. For many years, people have studied many methods to solve the hydraulic imbalance of the pipe network, from measuring flow to measuring return temperature, from manual static valves to dynamic self-operated valves. So far, there has been no effective solution to the secondary Pipe network hydraulic imbalance problem. [0003] With the development of the Internet of Things technology, it has begun to try to use the Int...

[0002] The hydraulic imbalance of the secondary pipe network of the central heating system is a long-term operational problem that cannot be solved. The hydraulic imbalance causes the temperature in the heat users' homes to be uneven. Heat and power consumption have increased significantly. For many years, people have studied many methods to solve the hydraulic imbalance of the pipe network, from measuring flow to measuring return temperature, from manual static valves to dynamic self-operated valves. So far, there has been no effective solution to the secondary Pipe network hydraulic imbalance problem

[0003] With the development of the Internet of Things technology, it has begun to try to use the Internet of Things technology and electric control valves to regulate the balance of the secondary pipe network. Many companies have developed products for the balance of the secondary pipe network, because these products do not consider the heat exchange station The linkage relationship with the heat inlet balance of the second network leads to the fact that the operating parameters of the heat exchange station cannot be coordinated with the heat inlet balance process. Not only does it require manual experience to intervene in the operation of the heat exchange station, but also the balance effects of each heat inlet are inconsistent, all of which belong to the thermal The transitional product of inlet balance control, or because the current secondary pipe network balance system cannot be linked with the operating parameters of the heat exchange station, the secondary pipe network cannot achieve hydraulic balance under the condition of the minimum circulation pump flow
