I think, your diagram is a 100% OA system with pre-heat. The zone and plants are not shown. The plant connections to the coils and the flow rate are shown.
I do not know the language, but deduced the operation by looking at the colour, arrows, and the temperature values.
The lower path is the OA inlet, pre-heat exchanger, fan, coils, to outlet to the zones The upper path is the turn air path. I am assuming that it is an air loop.
The environment is at 14.7°C. Pre-heat raised this to 19.5°C and then to 20.3°C by the heating coil. The return air is at 22.0°C, and is reduced to 18.1°C after the heat exchanger.
There are other values for relative humidity, pressures, etc. Some may be range limits.
Blue is cold, and red is warmer. The system is in the heating mode.
The diagram looks like a commonly used computer controlled system display screen. The use of this type of diagram is to centralize the monitoring of the plants for a large installation.
There may be other diagrams for different part of the system.
Those running EPlus should have a few of these diagrams so that the system node values can be filled in readily for system debugging purposes.
The diagram posted, I think, is only part of the installation.

Hey,
I took on picture of the system view by the software.
But I don't understand how it's work, where is the air input and output, air recycling, cooling zone...
someone could help me ? I never study this kind of system at school...
