New Wave in Climate Separation Technology What is Invisidor? Contents New Wave in Climate Separation Technology 1 What is Invisidor? What Makes an Effective Air Curtain Patented Rectifier Discharge Velocity Discharge Temperature Automatic Control Invisidor CA air curtains are the ideal solution for retailers and consultants to combat the issue of climate separation across their outlet or office building doorway. Using a combination of rectifier technology, air velocity and temperature control they deliver greater comfort to staff and customers alike, all year round, in all weathers. CDF...

What Makes an Effective Air Curtain? Patented Rectifier A critical factor when selecting an effective air curtain is ensuring that incoming air is conditioned to an acceptable temperature as it enters the building. For this to be achieved, the air curtain jet must cover the full width of the building entrance, so that it cannot be bypassed by incoming air. However, ensuring the jet reaches the floor level is more challenging. Along with the TNO wind facility at Apeldoorn in the Netherlands, Biddle has successfully developed a patented rectifier to minimise turbulence in the discharge...

Air Volume On more demanding days it is usual to increase the operational speed of an air curtain. Similarly on milder days the speed would be reduced. A standard air curtain with a fixed area discharge grille, means the air velocity increases or decreases accordingly, resulting in a drop in energy efficiency and comfort. One of the important differences between the Biddle CA2 air curtain and a standard air curtain is the inclusion of a patented damper mechanism. This assembly helps maintain the optimum relationship between air volume and discharge velocity – which we refer to as the air...

CFD Software for Air Curtains Application CFD (Computational Fluid Dynamics) is a technique for modelling air flow and is an ideal tool for simulating the effects of air curtains in real-life building scenarios. It has already been used effectively during the design process of the Biddle air curtain range to optimise parameters such as discharge temperature and velocity. After extensive collaboration with the engineering department at the University of Warwick, Biddle now has a CFD package specifically designed for modelling air curtains and other ventilation equipment in the built...
