    Airtècnics experimented R&D department works together with the UPC Technical University of Catalunya (Barcelona, SPAIN) to incorporate to our air curtains the latest technology to achieve the optimum performance and efficient operation.

    Airtècnics has a long term collaborative research project with Heat and Mass Transfer Technological Centre CTTC-UPC.

    Air curtain performance is evaluated in terms of energy saving and entrainment rate, applied to different applications jointly with surrounding spaces and conditioned rooms. Doorways are studied with and without air curtains.

    University works with mathematical formulation, numerical resolution and experimental validation of air curtains heat and mass transfer phenomena.

    The CFD computational code has been adapted to air curtains analysis by university researches. Then the results are verified and validated with experimental results at their own climatic chamber.

    Thanks to this collaboration Airtècnics has a simulator of air curtains behaviour depending on each situation. We have the possibility of introducing all necessary parameters of the air curtain and surroundings, to analyze the situation and select the most efficient air curtain.

    Internal geometry, turbulence intensity levels, jet angle discharge, velocity profile, lamellas geometry, etc…are factors taken into account on the studies.

    We can also calculate the energy saving and CO2 emission reduction when an efficient air curtain is installed on a doorway.

    Applying the acquired know-how to our units design, Airtecnics air curtains are at the cutting edge of air curtains knowledge and technology.
