Vehicle Climate Control Systems

Exploring the cabin climate in IBP’s unique flight test facility (FTF)

At our Holzkirchen branch, we perform tests in a unique flight lab (Fraunhofer Flight Test Facility FTF), in which a segment of a wide-bodied aircraft is installed in a low-pressure chamber. In the scope of the European aviation research project »Clean Sky« we enhanced our facilities by adding a business jet platform, which enables us to safely perform complex tests involving in-flight and ground situations without taking off. The test facilities are complemented by the AirCraft Calorimeter (ACC), which allows simulating thermal shocks or rapid decompression.

In addition to exploring the cabin climate of vehicles and airplanes, our researchers focus on developing and validating the overall system under realistic conditions, identifying innovative solutions for air-conditioning. During their experiments, our scientists not only examine the cockpit, the passenger cabins and the cargo holds but also the aircraft avionics (including all electric and electronic devices) in regards to energy performance and user requirements. In the scope of international projects and on behalf of manufacturers and suppliers to the aerospace and automotive industry, tests on thermal passenger comfort, thermodynamic relations and condensation are carried out.


Flight Test Facility - the Fraunhofer IBP flight lab

In the flight lab, which is the only one of its kind in the world, we study all aspects of the interior climate - from comfort and hygiene to the distribution of environmentally-friendly fire-extinguishing agents in the cargo area, and right through to analyzing the formation of condensation on the aircraft structure.


The Fraunhofer Indoor Air Test Center (IATC)

The Fraunhofer IBP Indoor Air Test Center (IATC) in Holzkirchen is used to carry out tests on indoor climatic conditions and air quality. Typical tests include evaluating the energy consumption of various air-conditioning measures, determining the efficiency of air purification systems for indoor use, or detecting airborne pollutants with the aid of sensors.


The Lining and Insulation Test Environment (LITE)

The Lining and Insulation Test Environment (LITE) consists of two climate chambers that can be individually conditioned. Each chamber contains four frame bays which are used to study how the cabin climate interacts with the aircraft sidewall. 


DressMAN comfort measuring system

Objectively measuring how people perceive thermal comfort in a vehicle - that is possible thanks to the DressMAN and its sophisticated sensor system.
