Fujitsu General’s new Smarter Building Controller — introduced by Fujitsu General and technology partner,Ventacity Systems — offers a plug-and-play building management system for use with Fujitsu General’s Airstage heating, ventilation, and cooling systems.
Samsung’s DVM Chiller combines VRF systems with traditional chiller systems for commercial applications. According to the company, the DVM Chiller is energy efficient, compact, ecofriendly, and beneficial as it can inherit existing water facilities. Operational modes of the system can be adjusted to allow for seasonal requirements.
DriSteem says it has introduced three new product options for the Wetted Media System, meeting the requirements of today’s systems that often require cost efficient evaporative cooling and humidification.
Fujitsu launched a new Wi-Fi solution for its Airstage line. This Wi-Fi tool allows installers to operate a Fujitsu Airstage VRF system from anywhere with a smartphone, laptop, or tablet. Fujitsu’s Airstage VRF systems are controlled from a webpage or by using an iOS or Android App. A cloud server manages the entire process. Many HVAC functions can be remotely operated. These include: on/off, mode (heating, cooling, dry, auto, air circulation), change or set temperature, and set schedules and timers.
A new line of dedicated outside air systems (DOAS) from the YORK® brand of Johnson Controls includes a range of 100% outside air units and mixed air units. With heat pump operation and water source operation, as well as a hot water heat option, the new line of air systems delivers more combinations of heating and cooling. The systems also feature an internal energy recovery wheel that pre-conditions outside air and reduces heating and cooling loads by transferring energy between the exhaust airstreams.
SPX Cooling Technologies announced a redesign of its Marley AV line of factory-assembled single flow cooling towers. The new induced draft crossflow design features both single- and multi-fan models and a broader tonnage range from 122 to 772 nominal tons and flowrate of 117 to 1,541 gpm (27 to 350 m3/hr).The AV provides a compact footprint and is well-suited to support air conditioning and refrigeration systems as well as light industrial loads.
Laars Heating Systems now offers a 150- to 2,500-gallon electric water heater from 12 to 360 kW. The systems feature 150 psi ASME code glass lining, ASME temperature and pressure relief valve, internal fusing (above 120 amps), and magnesium anode rods.
Fujitsu General America Inc. has expanded its Airstage™ V-II VRF equipment line of VRF heat pumps with enhanced capabilities and operational efficiencies. The latest series now includes 6-, 8-, and 10-ton condensers, helping to reduce the number of condensers in certain configurations.
On Demand Our society has become highly dependent on electrical power. It is the underpinning of virtually everything, and we take it for granted in everyday life at home, work, and in many cases, public transportation. Moreover, virtually all of the critical infrastructure for communications, security, emergency services, and life safety depend on power. Climate Change, in general, and the record weather extremes will continue to increase the likelihood of utility power interruptions as well as risks to life and property. In the new age of 100-year events becoming more commonplace, it has become clear that there is virtually no place that is totally immune to natural risks. Therefore, backup power has become almost as important as primary utility service, and, in many cases, it's a necessity.
On Demand It’s not the heat, it’s the humidity! At Pfizer Pharmaceutical, this isn’t simply a notion of comfort, it’s a battle cry for engineers responsible for controlling the indoor environment at the company’s pill-manufacturing facility in Puerto Rico. So, when Pfizer began a large HVAC renovation, the company knew tight ductwork was essential. After several failed attempts at traditional manual sealing, contractors recommended a new internal approach to duct sealing. To prove success, painstaking measurements were taken before and after the work was done.
On Demand As the HVAC market continues to expand and Variable Refrigerant Flow (VRF) technologies continue to evolve, the demand for professionals with VRF expertise will only grow. This presentation provides thorough insight into the requirements, advantages and opportunities associated with specifying VRF systems and addresses the common misconceptions professionals may encounter in the field. Additionally, the speakers will detail VRF-specific concepts including simultaneous heating and cooling as well as how VRF fits within building industry trends such as Strategic Electrification.
While the basic concept and need of backup power systems has not changed, the increased likelihood of power outages has put greater reliance on backup power systems, making the their reliability more important than ever. When a utility outage occurs, the backup generator is expected to immediately start and support the load; however, even the best emergency backup power system, utilizing the highest-quality equipment, can be rendered useless if not properly maintained.
Engineered Systems magazine’s September 2019 issue questions the need for multiple building codes that cover the same subjects, examines the dos and don’ts of power systems for critical facilities, offers tips on how to select the proper centrifugal pump circuit flow controls, and much more.
