Abstract

The article deals with the description of the simulation setup for scaled-down imitation, which is located in audience of SUSU number 101/2. The setup allows you to simulate thermal-hydraulic conditions of engineering systems for different objects and has the following functions:

1. Modeling of peculiar properties of different distribution conduits: domestic single pipe system with the bottom admission of heat transfer agent; European single pipe system with an overhead admission of heat transfer agent with alternative heating devices and thermostatic controls, European double-pipe system with thermostatic controls.

2. Carrying out the hydraulic balancing of the heat network.

3. Testing of all standard situations: changes in environmental parameters (daily and seasonal changes of temperature, changes in solar illumination, changes in direction and speed of wind load); the impact of the consumer (the presence of internal heat sources (the number of people in the room, application of additional heating devices, cooking appliances, work of lighting systems), forced ventilation of the room through opening the windows and doors; compulsory regulation or disable of the main heating devices, changes in the conditions of heat transfer from the heating devices to the air space).

4. Testing of emergency and accidental situations.
