The indoor climate laboratory offers a highly controlled environmental conditions for investigating diverse topics related to thermal comfort, indoor air quality, infection risk, and ventilation strategies. This laboratory is equipped with state-of-the-art equipment, including:
Climate chamber:
- 3 x 3 x 2.44 m (L x W x H)
- Each surface can be separately heated or cooled (4 walls, ceiling, floor)
- Ventilation system for both heating and cooling
- Tracks on the ceiling to mount various sensor
Breathing thermal manikin (nicknamed 'Feelix'):
- Simulates heat generation from the human body
- 22 body segments, separately controllable
- Male body geometry (standing body height: 1.76 m)
- Different control modes: surface temperature, heat flux, or comfort mode.
- Breathing system with air heater and humidifier
- Connections to introduce tracer gas or particles into the exhaled air
Tracer gas system:
