New chiller tech solves key challenges on refrigerants, efficiency and cost

Danfoss has responded by sharing information on new and emerging chiller technologies which the company believes will help OEMs to reduce system design time, and deliver comfort in commercial buildings without undue price pressure. Easing the transition to lower-GWP refrigerants Not content with the market’s widest range of compressors, heat exchangers, valves, sensors and line components qualified for lower-GWP refrigerants, Danfoss is continuing to develop new, drop-in components to make transition as easy as possible. Currently, R1234ze, R513A, R32 and R452B are at the top of the agenda, and the company has pledged to support further low-GWP alternatives as they emerge in future. New advances in oil-free chiller technology HVAC professionals now have more opportunity than ever to take advantage of the benefits of an oil-free approach Danfoss Turbocor TTH/TGH high-lift compressors Danfoss Turbocor TTH/TGH high-lift compressors are the latest compressors to use the award-winning, variable speed, magnetic bearing technology. From early 2019, the new Danfoss Turbocor TTH/TGH high-lift compressors will offer outstanding full- and part-load efficiency, low vibration and sound, a small footprint, and reduced maintenance. Their high-lift capability is suitable for high-lift applications like air-cooled chillers, heat pump and heat recovery. Meanwhile, the existing Danfoss Turbocor TT/TG Series compressors are now available for R-513A, a low-GWP, non-flammable (A1) alternative refrigerant to R-134a. As a result, chiller manufacturers will have another option to meet future HFC regulations in low-lift, oil-free applications. Read more
