Carrier has collaborated with Barrisol, the HVAC ceiling solutions specialist, to develop a range of integrated air conditioning solutions said to deliver outstanding comfort, enhanced indoor air quality (IAQ), and low-operational costs.
The new advanced ceiling solutions provide a high-quality, stable indoor environment, and the highest levels of aesthetic design and are designed for any application where precise control of temperature and very low air velocities are required.
The initiative is part of Carrier's Healthy Buildings Programme, which provides customers access to proven technologies that contribute to safer and more productive buildings.
Through their combination of low velocity airflow, draught elimination, and ability to maintain stable temperatures throughout the occupied space, the Carrier and Barrisol solutions achieve a comfort rating of Class A* for both cooling and heating, the highest possible under ISO 7730, the relevant international standard for measuring thermal comfort in buildings.
The system is available in two options: the Barrisol Clim and Barrisol Cloud Clim, both featuring Carrier products.
Barrisol Clim uses a ceiling made from a bio-sourced membrane that is stretched and fixed in position, 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 removed for servicing.
Juan Jose Francisco Diez, Carrier’s marketing manager for airside products in Europe, said: "Comfort and well-being are now widely recognised as key factors influencing people's productivity and performance at work and play, not to mention their importance to everyday life and enjoyment. Temperature stability, low noise and draught elimination are key to this. The new advanced Barrisol ceiling air conditioning solutions featuring Carrier products deliver exceptional performance in all these areas. We believe they will prove highly attractive as people look to upgrade indoor environments and take IAQ and occupant comfort to the next level."
For enhanced IAQ, the Barrisol Pure Clim option uses ultra-violet (UV-C) lamps within the ceiling void to target pathogens as part of a healthy buildings programme. It 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.
While Barrisol Clim uses low-speed air diffusion and thermal radiation from the whole ceiling area to maintain highly stable, comfortable conditions, Barrisol Cloud Clim uses a combination of convection and direct thermal radiation from the suspended panels to maintain required conditions. To further enhance comfort, modular panels automatically adapt airflow direction and velocity according to temperature, minimizing draughts.
A wide range of Carrier FCUs can be selected to suit the application, including the company's recently developed ultra-low-profile Idrofan 42EP, at just 150mm high, said to be the slimmest and most compact FCU available.
