HVAC systems in commercial buildings consume a lot of energy, which is why many building owners and managers are looking at replacing their older, inefficient equipment with new high-performing systems.
Variable refrigerant flow (VRF) technology is relatively new to the U.S., yet it has quickly become a very popular option in the commercial market. VRF is now moving into the residential market as well.
This Wi-Fi tool allows installers to operate a Fujitsu Airstage VRF system from anywhere with a smartphone, laptop, or tablet. Airstage VRF systems are controlled from a webpage or by using an iOS or Android app.
When Smouse decided to improve its facilities, the school needed a versatile HVAC upgrade that balanced efficiency with the unique design needs of a historic building with several floors of varying environments. Most importantly, Smouse required a system that would provide an optimal comfort environment for its students while preserving the architectural integrity of the building.
The J-IIS variable refrigerant flow (VRF) technology is designed for smaller residential, multi-housing, and light commercial uses with equipment available in 3- and 4-ton sizes.
The ProSpace variable refrigerant flow (VRF) wireless control interface creates an open communication platform that allows Trane VRF systems to integrate with hotel room thermostats and building-level control systems. The control is equipped with motion and infrared sensors.
While many educational sessions were presented at the Air-Conditioning, Heating, and Refrigeration (AHR) Expo, perhaps the most popular was the course on global HVAC trends offered by the Building Services Research and Information Association (BSRIA).
LG Electronics USA Air Conditioning Technologies has added two more industry veterans, further enhancing its commercial applied sales and customer experience organizations. These changes address the evolving needs of the U.S. market and support the growth of LG’s variable refrigerant flow (VRF) technology.
As contractors become better versed on the benefits of ductless technology, they play a key role in educating homeowners as to why duct-free technology may be a better solution in terms of efficiency and design flexibility.
V-II 230V/3-phase, zoned variable refrigerant flow (VRF) systems offer large capacity and operational efficiencies up to 24.30 IEER to Air-Conditioning, Heating, and Refrigeration Institute (AHRI) 1230 standard and are ideal heating/cooling solutions for small and large buildings.
