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.
Armstrong will play an integral role in the introduction of unitary products
February 13, 2017
Armstrong comes to Fujitsu General America after a long tenure at Johnson Controls Inc., where he served in several sales and marketing functions, most recently as vice president of sales and marketing, VRF/DFS, where he was responsible for starting the VRF business in North America, and he served on multiple teams including the channel management team and the global commercial leadership council.
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.
The Convent of St. Dominic finds energy savings, extended comfort in VRF technology
January 30, 2017
The Convent of St. Dominic is the headquarters for the Sisters’ housing administrative offices, a convalescent wing, and large chapel in Blauvelt. The 100,000-square-foot, five-story brick building was being heated with an archaic steam system. In addition to operating expense, the lack of control over the facility’s heating system was a problem, especially in the hospital and living quarters.
Construction supply facility reports 40 percent savings
January 9, 2017
Euclid Chemical, based in Cleveland, has been supplying the construction industry with products to improve the strength, appearance, and usability of concrete since 1910. Now a large, multi-national corporation, Euclid Chemical’s main offices are in a two-story, 15,000 square foot building that also contains laboratories where it develops products ranging from sealants to micro synthetic fibers.
Until recently, the building relied upon an aging variable air volume (VAV) system with terminal reheat to keep its offices comfortable and to maintain environmental conditions in the laboratories even though records showed the system had not performed as designed.
Mitsubishi Electric U.S. Inc. Cooling & Heating Division (Mitsubishi Electric), a manufacturer of Zoned Comfort Solutions™ and variable refrigerant flow (VRF) cooling and heating systems, is hitting the road with their newest demo truck. The truck, which launched in October 2016 equipped with CITY MULTI® VRF technology, is the latest addition to the road show fleet.
In this issue, we present the Refrigeration Showcase, featuring new products from ice makers to reach-ins to display cases and more. We also look at heat pump technologies, how they benefit customers, and how you can service them.
