Indoor Air Quality
Advanced ceiling solutions for precise control
CARRIER HAS COLLABORATED with Bar- risol, the world-leader in HVAC ceiling solutions, to develop a range of integrated air conditioning solutions that deliver outstanding comfort, en- hanced indoor air quality (IAQ), and low-opera- tional costs.
The new advanced ceiling solutions provide a high-quality, stable indoor environment, the highest levels of aesthetic design and are ideal for any application where precise control of temper- ature and very low air velocities are required.
The initiative is part of Carrier's Healthy Build- ings Program, which provides customers access to proven technologies that contribute to safer and more productive buildings.
Through their combination of low velocity air- flow, draft elimination, and ability to maintain highly stable temperatures throughout the occu- pied space, Carrier and Barrisol advanced ceiling solutions achieve a comfort rating of Class A* for both cooling and heating, the highest possible under ISO 7730, the relevant international stand- ard for measuring thermal comfort in buildings.
“THE PRODUCTS ARE IDEAL FOR ANY APPLICATION WHERE PRECISE CONTROL OF TEMPERATURE AND LOW AIR VELOCITIES ARE REQUIRED.”
The Carrier and Barrisol ceiling air condition- ing system is available in two options: the Barri- sol Clim featuring Carrier products and the Bar- risol Cloud Clim featuring Carrier products.
Barrisol Clim featuring Carrier product tech- nology uses a ceiling made from a bio-sourced membrane that is stretched and fixed in posi- tion, spanning a room.
Air conditioning is delivered into the ceiling void by a concealed Carrier fan coil unit (FCU), and is gently diffused downward through the
gap between the membrane edge and the walls – with such low velocity it is barely noticeable.
Air is extracted from the conditioned space vertically upwards, along the outer walls via a concealed bulkhead, and back to the FCU. It is then filtered, heated or cooled, mixed with fresh air and returned to the room via the ceiling void.
Installation for contractors is quick and easy, with structural fixtures that can be rapidly re- moved for servicing.
Juan Jose Francisco Diez, Carrier’s marketing manager for Airside products in Europe, said comfort and well-being are now widely recog- nised as key factors influencing people's produc- tivity and performance at work and play.
He said stability, low noise and draught elimi- nation are key to this.
“The new advanced Barrisol ceiling air condi- tioning solutions featuring Carrier products de- liver exceptional performance in all these areas,” he said.
“We believe they will prove highly attractive as people look to upgrade indoor environments and take IAQ and occupant comfort to the next level."
Components are designed to help buildings achieve the highest levels of environmental per- formance. For example, ceiling membranes are made from 100 per cent recyclable material that

contains a plant-based plasticiser, and weak A+ class in terms of VOCs emissions (volatile organ- ic compounds). Support profiles are made from 80 per cent recycled aluminium.
Ceiling membranes can be printed, opening up possibilities for creative interior design, which is not possible with other types of air conditioning.
For enhanced IAQ, the Barrisol Pure Clim fea- turing Carrier option uses ultra-violet (UV-C) lamps within the ceiling void to target pathogens as part of a healthy buildings program.
The Barrisol Cloud Clim featuring Carrier product technology version of the system uses modules that are suspended from the ceiling, through which conditioned air is delivered into the room. Air can be fed into ceiling modules via an FCU concealed nearby or located in a plenum.
It uses low-speed air diffusion and thermal ra- diation from the whole ceiling area to maintain highly stable, comfortable conditions.
The product uses a combination of convection and direct thermal radiation from the suspend- ed panels to maintain required conditions. To further enhance comfort, modular panels auto- matically adapt airflow direction and velocity according to temperature, minimising draughts.
