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.
Maintains architectural integrity in historic Iowa school building
May 22, 2017
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.
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).
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.
These VRF units feature DC, inverter-driven compressors for precise temperature control. They are available in up to 3,280 feet (1,000 meters) of total piping length and include up to 36 indoor connections, which make them easy to install, network, and maintain.
There is nothing like a grand opening on Broadway — and, on such occasions, rarely is the HVAC industry cast in a starring role. That changed recently as “Air Stage,” Fujitsu General America Inc.’s Solution Center, officially opened on 1450 Broadway in the heart of Times Square in New York.
