Air-Handling Units
Three air handling units (AHU) provide conditioned supply air to the different test benches. The units can also be connected among each other. That means that AHU1 provides the outdoor air and AHU3 provides the extract air for AHU2. AHU2 is the device under test and different components like heat exchanger and enthalpy wheel can be investigated under well-defined conditions. The supply air temperature of the units can be controlled in a range from -15 °C up to 40 °C and the supply air relative humidity can be set between 5 % and 80 %.
