The "Indoor Climate Lab" (still under construction) is a highly flexible test bench for investigating various aspects of indoor comfort and occupant behavior. The test bench consists of a specially made climatic chamber with internal dimensions of 7.9 m x 4.6 m x 2.8 m. In this chamber, thermal, ventilation, (psycho-)acoustic and lighting effects can be simulated as in a real office room or a conference room. Using a partition wall, the chamber can be separated into two rooms for parallel experiments.
The climatic chamber is designed with high modularity and flexibility: walls, ceilings and floors in the chamber are built up with almost 100 modular and interchangeable elements, so that different ventilation concepts can be adapted depending on the scenario. The surface temperature of each element can be regulated by means of the embedded capillary tube mats in it, which can generate different surface temperatures from +12 ° C to +40 ° C. The surface structure of elements can be freely designed, which can change the impressions and adapte the acoustic properties in rooms. In the floor and ceiling area, there are also connections for a hydraulic supply, so that different heat transfer systems, such as radiators, cooling ceilings or heating surfaces can be installed in the room.
For the air conditioning, two heating, ventilation and air conditioning (HVAC) devices are set up for each room separately. The supply and exhaust air volume flow of each room is between 150 and 450 m³ / h. Accordingly, the air exchange rate of the room can be regulated from approx. 3 to 9 h-1. The supply air can cover a temperature range from +12 °C to +40 °C and a relative humidity range from 10 to 90%.
An LED / OLED lighting system, as well as a binaural sound system are installed in the lab. These can be used to generate the different illuminance levels, light color temperature and background noise.
