Measurement setup

Equipment to measure the average air temperature and air humidity in the climate chamber.

ServiceLab Heat Pumps and Chillers

ServiceLab Heat Pumps and Chillers offers the most modern technology for developing, measuring and characterizing heat pumps and chillers, as well as their components. The modular test rig concept makes it feasible to test different types of technology and system configurations over a broad spectrum of operating conditions with different heat transfer media (air, water, brine). In addition to systems with an electric connection power of up to 35 kW, thermally driven equipment – heat, natural gas or test gas – can be measured. The laboratory is equipped with an integrated safety concept which allows components and systems with flammable refrigerants or ammonia to be constructed and measured.

Test objects with heating or cooling capacity of up to 100 kW (50 kW in calorimetric operation) can be measured in a calorimetric double climate chamber at temperatures between -25 °C and +50 °C and air humidity range between 25 % and 95 %. In addition, the laboratory also has several conditioning units for water, brine and air, which can provide the relevant medium at temperatures from -25 °C to +95 °C in a power range up to 40 kW. In the three air units, a volume flow range between 80 m3/h to 5000 m3/h can be testet from -15 °C up to +50 °C and humidity range from 15 % up to 95 %.

All measurement and conditioning technology is suitable for measurements according to the common technical standards. Beyond this, we cooperate with our partners to develop individual measurement procedures, which enable efficient and cost-effective development and optimization of devices and more complex systems by realistic, dynamic measurement sequences,
including ”hardware-in-the-loop“.

Furthermore, component-specific test stands are designed and operated, where advanced measurement and analytical technology from fluid mechanics, acoustics, vibrations and gas analysis is used to address specific questions (e.g. particle image velocimetry (PIV), Laser-Doppler-Anemometry (LDA), shadowgraphy and gas chromatography).
