In the training manual, the behavior of the heating system with elevator mixing in non -calculated operating modes is studied in detail. The accuracy of the calculations performed using the calculated ratios for elevator nodes recommended for the use of the output section of the elevator’s nolers at the entrance to the cylindrical mixing chamber and at a distance from it.
The study of the heating system was carried out for various design temperature schedules for regulating heating networks used in practice.
The behavior of the heating system is considered when changing the resistance of the adjusting reinforcement located on the mixing line, before and after the heating system, in front of the elevator node in the feed line. Depending on the resistance of the corresponding regulatory authority, the coefficient of mixing, the temperature of the coolant at the input and at the output of the heating system, the costs of network water and circulation flow, the thermal power of the heating system, and the average temperature of the premises are determined.
The influence of circulation gravitational pressure on the operation of the heating system with low disposable apartments in front of an elevator node has been investigated.
Assess the parameters of the heating system with a significant decrease in the temperature of direct network water.
As a result of the study, it was shown that the behavior of the heating system with elevator mixing when changing the resistance of the regulatory reinforcement and heating devices is quite conservative. The resistance of the reinforcement significantly affects the value of the mixing coefficient, but this dependence is much weaker for the thermal power of the heating system, the average air temperature in the rooms, temperatures and the costs of coolants
