Rotary heat exchanger for heat recovery
Function
Decentralised supply and extract air units for room ventilation, isothermal units that compensate for the heat loss due to ventilation according to the technical data.
An EC centrifugal fan takes in the outdoor air which then flows through the motorised shut-off damper and the outdoor air filter.
The outdoor air then flows through the rotary heat recovery unit, which can be switched off if it is more energy efficient.
If necessary, the air is heated by the heat exchanger before it is discharged towards the ceiling with a high propulsive force.
The extract air first passes the extract air filter, then flows through the heat recovery unit, the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air.
If the power fails, the outdoor air and exhaust air dampers are closed to ensure fire protection and frost protection and to avoid draughts. This is ensured by a capacitor in each actuator.
The supply air is discharged near the ceiling with a medium velocity, and the selected air outlet ensures good overall room ventilation.
Once the air reaches the opposite wall, it moves downwards and eventually through the entire space. By the time the airflow reaches the occupied zone it has a very low velocity.

Decentralised ventilation unit TROX SCHOOLAIR-S-HV-0-EH for supply and extract air, with rotary heat recovery unit and electric air heater, for floor-standing installation:
FSL-CONTROL III Regler
Including control system FSL-CONTROL III, as described below:
FSL-CONTROL III is described as stand-alone single room control equipment with a simple timer. Optional expansions, such as connection to the central BMS provided by others via Modbus TCP / Modbus RTU, BACnet MS/TP or BACnet IP, humidity sensors, return flow temperature sensors, electromotive valve actuators or pressure-independent control valves are included in the product range, but must be replaced with the standard components in the following description. A room temperature signal is also required. Various room control panels and sensors are available for this purpose. The corresponding optional equipment text modules can be found in the appendix of the following standard equipment for room-autonomous operation. We recommend commissioning by our technical service. You will find related text modules below.
