Carrier
Carrier has collaborated with Barrisol, a world-leader in HVAC ceiling solutions, to develop a range of integrated air conditioning solutions that 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 ideal 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, draft elimination, and ability to maintain highly stable temperatures throughout the occupied 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 standard for measuring thermal comfort in buildings.
The Carrier and Barrisol ceiling air conditioning system is available in two options: the Barrisol Clim featuring Carrier products and the Barrisol Cloud Clim featuring Carrier products. Barrisol Clim featuring Carrier product technology 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. Components are designed to help buildings achieve the highest
levels of environmental performance. For example, ceiling membranes are made from 100% recyclable material that contains a plant-based plasticiser, and weak A+ class in terms of VOCs emissions (volatile organic compounds). Support profiles are made from 80% 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 featuring Carrier option uses ultra-violet (UV-C) lamps within the ceiling void to target pathogens as part of a healthy buildings programme. X

NevadaNano
NevadaNano,has entered into a partnership with Recom Industrial in Genova, Italy, to deliver the Gas Point Safe Zone system, said to be the world’s first Molecular Property Spectrometer (MPS) fixed gas sensor for naval and shipyard environments. The Gas Point Safe Zone MPS-driven detection system reduces
maintenance costs and increases uptime, protecting workers in virtually any environment where flammable gas mixtures are present. In addition to marine applications, the new standalone Gas Point detectors are ideal for use in the petrochemical, agricultural, chemical, oil and gas, airline, and mining industries. Using MPS sensors, a single Gas Point detection tool quickly detects and precisely quantifies more than 12 different types of gases and mixtures, improving safety conditions. Those who work in a work environment at risk can rely on a single, extremely reliable device to warn promptly of the onset of danger. Unlike traditional models, the MPS sensor requires only a standard factory calibration eliminating the need for periodic field calibration for up to five years. With built-in compensation for temperature, pressure, and humidity, the gas sensor can detect methane and combustible gas with exceptional accuracy even in rapidly changing environmental conditions, minimizing false positives. Based on microelectromechanical system (MEMS) technology, the gas sensor device is very robust and immune to drift, decay or poisoning. X

Homevent
To combat the challenges associated with providing adequate ventilation in hard-to-naturally ventilate spaces below suspended ground floors, Homevent has launched its mechanical ventilation alternative. The MORI WMF Weatherproof Multi-Functional Sub-Floor Ventilation Fan is designed to control air moisture content, as well as radon gas, in sub-floor spaces. The health concerns associated with radon gas make effective ventilation critical, and even in areas where this is not an issue, high moisture content can decay timber – ultimately leading to extortionate remedial costs.
For this reason, mechanical rather than natural ventilation is often required, especially when existing natural ventilation measures such as airbricks have become blocked over the years. However, fans mounted within the sub-floor space can be expensive to run, struggle to cope with the extremes of temperature within such spaces, and will often require impractical maintenance. Inevitably, this results in fans not being checked and cleaned, which drastically reduces the effectiveness of a ventilation unit. X
