description: The subject of the graduate qualification work is âAnalysis of balancing devices of the heating systemâ.
The given work is devoted to the analysis of the influence of balancing devices on the heating system using existing calculation methods in order to identify the optimal technical solution. The research set the following goals:
1. To analyze the existing methods of hydraulic calculation and selection of balancing devices of the heating system.
2. To create a simulation model of the calculation according to existing methods for the selection of balancing devices to determine the feasible technical solution.
3. Verify the presented method for determining the feasible technical solution on the example of an apartment building.
In the course of the work, a simulation model of the calculation was compiled according to existing methods for selecting balancing devices and a method was proposed that allows us to determine a feasible technical solution based on an analysis of two main system parameters - hydraulic losses and overheating. 
The calculation according to the presented method for an apartment building in St. Petersburg is made. The calculation showed that the regulation of the heating system using various types of balancing devices increases the hydraulic losses of the system, while the analysis of the overheating of the MKD rooms showed that the smallest overheating was obtained using automatic balancing valves, which makes it possible to choose automatic balancing valves as the optimal technical solution.
