This technology was created with the intent to provide facility decision-makers with the tools needed to select, rate, and configure Johnson Controls Equipment on their own, including chillers, air-handling units (including factory-packaged controls), packaged systems, and related components.
Carrier announced the commercial availability of its AquaEdge® 19DV in North America. The centrifugal chiller features Greenspeed® intelligence and a low global warming potential (GWP) refrigerant R1233zd(E), which has a GWP of ~1. Carrier officials said the AquaEdge 19DV has an efficiency that is more than 40% higher than ASHRAE® 2016 guidelines, has low sound, and is capable of series counterflow configurations.
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.
STULZ has added chillers with a stepless capacity control (EC compressor) and an output from 20 to 100 kW to its portfolio. Chillers from the CyberCool Indoor series have been designed for indoor installation. The new version was specially engineered to precisely adapt to low or fluctuating heat loads. With a maximized temperature range from 4ºC to 18°C at the chilled water outlet, the CyberCool Indoor is suitable for a broad range of applications including data centers, medical technology, and process industries.
Quantech has expanded its QTC3 line of Air-Cooled Scroll Chillers up to 225 tons. The extended capacity of the QTC3 offers a more cost competitive solution to 225-ton opportunities without sacrificing size, quality, and efficiency, according to the company.
Trane is expanding its Series S™ CenTraVac™ chiller line with the new CVHM model. The Series S CVHM chiller model is available in 170-370 ton range and can be applied to any commercial building including retrofits and system replacements. The company says the chillers are designed to fit in varied spaces to addresses customer needs for a simpler replacement in existing, tight structures.
SEMCO LLC has introduced the NEUTON™–Multiple Zone, a controlled chilled beam pump module (CCBPM) capable of controlling active chilled beams in up to five small rooms in office buildings, hospitals, schools, or other commercial buildings.
To help chilled water systems reach their efficiency potential, Carrier has further enhanced its ChillerVu™ plant control system to include the new Carrier ChillerVu chilled water system optimizer. The new optimizer extends control efficiencies beyond the chiller plant and improves the efficiency of the entire chilled water system, including AHUs, fan coils, and other chilled water distribution equipment. Based on laboratory and field tests, Carrier officials said adding the optimizer to a building’s chilled water system can yield energy savings in the range of 3% to 15% percent (versus non-optimized systems).
Automated Logic Corporation (ALC) has expanded its suite of optimization solutions for the WebCTRL® building automation system to include a new chilled water system optimizer. The new WebCTRL chilled water system optimizer minimizes the energy use of the entire chilled water system in a commercial building, including AHUs, fan coils, and other chilled water distribution equipment.
Engineered Systems magazine’s May 2020 issue examines the revitalization of air-cooled chillers in data center facilities, the viability (or lack thereof) of duct systems, the impact the coronavirus is having on the built environment, and much more.
