Our vision is a future-oriented HVAC technology.
To create an ideal indoor environment, components for heating, ventilation, air-conditioning and cooling (HVAC) are necessary. The HVAC systems used for the conditioning, transport and delivery of the treated air into the occupancy zone should work as efficiently as possible with regard to energy consumption.
For this reason, our team "HVAC systems” is developing future-oriented HVAC concepts. We not only consider the optimization of individual components in terms of energy efficiency, thermal comfort and profitability, but also the optimum interaction of these different components as a complete system.
To achieve these goals we use different simulation methods and a variety of experimental techniques. For component optimization, we apply CFD (Computational Fluid Dynamics) to accurately simulate the three-dimensional physical quantities. Our prototype construction lab allows us to create models quickly, which we then investigate empirically. Additionally, the laser optical measuring methods PIV (Particle Image Velocimetry), LDA (Laser Doppler Anemometry), PTV (Particle Tracking Velocimetry) and thermodynamic hydraulic measuring allow us to validate the simulation results experimentally. For the system optimization, we apply energetic simulations, whereby the operating behavior of the individual component and systems over longer periods of time are of prime importance. Therefore, they are modeled on a higher level of abstraction compared to CFD. We investigate the developed component and system solutions in our own test facilities experimentally and also perform field tests. The economic efficiency of the individual and overall systems is taken into account in the optimization process via the life cycle cost approach.
