In the whole heating system, the hydraulic balance problem of secondary pipe network is often neglected because of the difficulty in jurisdiction and regulation. As a result, the hydraulic imbalance of secondary pipe network is more common and serious, and the energy consumption and customer complaint rate of thermal network are high.


The most direct reflection of secondary network hydraulic imbalance:

•Main line, branch pressure drop difference is big;


•Flow imbalance;


•User's room temperature is not uniform;


•High energy consumption and operation cost


•Energy waste

The "last mile" of intelligent heating network is a crucial link in the whole intelligent heating system, which determines the final operation effect of the system.


The solution of the balance of the end of the secondary network solves the hydraulic imbalance of the secondary network through the balance transformation, collects the room temperature of the user through the intelligent heat network monitoring system, combines the weather forecast and historical control data, and conducts intelligent calculation and analysis, provides personalized control target for the thermodynamic station system, and makes real-time modification to the heat source load prediction model, optimizes the dispatch control of the heat network, so as to achieve the energy saving and environmental protection operation of the heat network to the maximum extent, and guarantees the good heating effect of heat users.


Solution One: Floor (unit stand pipe) dynamic balance+ Static balance of entry front end

End Balance of The Secondary Heating Network

Solution Features:

1.The dynamic balancing valve is installed on each floor (unit stand pipe), and the flow is distributed on the floor (unit);


2. Use the static balancing valve to balance the flow of each user in the floor (unit)


3. Less adjustment work, dynamic balance of flow between floors (units)


Solution advantage:

1. Excellent heating performance and low input cost


2. System debugging simple, debugging cycle short


3. When adjusting the single user flow, only in this floor (unit) mutual absorption, release


4. Solve the hydraulic distribution between layers (between units) and adjust the flow rate automatically according to the occupancy rate


Solution Two: Install the electric regulating valve of Internet of things separately

End Balance of The Secondary Heating Network

Solution Features:

1. Can be adjusted automatically by software


2. Less adjustment work, the adjustment effect can be monitored and evaluated online;


3. Internet of things electrical control valve, low cost, low power consumption, communication cost, easy maintenance.


Solution advantage:

1. Simplify system debugging


2. The system dynamic balance is realized conveniently and quickly


3. The intelligent heating network platform can be combined to achieve differentiated heating on demand


The solution of the balance of the end of the secondary network can evaluate the hydraulic adjustment effect of the secondary network in real time and calculate the system hydraulic loss scheduling, combined with the hydraulic imbalance analysis system of the secondary network developed by TSCC; can monitor the change of working condition and discover the accident spot in real time, and repair and deal with it in time; according to the data of thermal measurement system and household room temperature collection system, this scheme can accurately evaluate the heating effect and energy consumption indexes.

 End Balance of The Secondary Heating Network

•The problem of hydraulic imbalance of secondary heating network is solved;


•Solve the problem of unbalance of flow when the load changes in the heating secondary network;


•To solve the problem that the balance adjustment work of heating secondary network is too large to evaluate the effect;


•To solve the problem of large secondary network flow and high energy consumption of circulating pump in heat exchanger station;


•To solve the problem of overheating near end of secondary network and substandard heat supply at far end;


•To solve the problem of high water, electricity and heat consumption in the system.
