Air-cooled chillers

Paul Boughton

The Trane Sintesis family of air-cooled chillers are part of the Ingersoll Rand EcoWise portfolio of products designed to lower their environmental impact with next-generation, low global warming potential (GWP) refrigerants and high-efficiency operation.

Sintesis chillers offer customers a choice to use either R-134a or DuPont Opteon XP10 (R-513A), a next-generation, low-GWP refrigerant to address sustainability objectives. The portfolio provides more than options for refrigerants. The portfolio also:

* Achieves Energy Efficiency Ratio (EER) and European Seasonal Energy Efficiency Ratio (ESEER);

* Uses up to 40% less refrigerant than traditional tube/fin and flooded heat exchanger technology due to the micro-channel condenser coil and the compact, high-performance, integrated, low charge (CHIL) evaporator design;

* Reduces noise and improves acoustics through its factory-installed acoustic treatments for consistent, quiet operation to meet specific application requirements. A user-selectable noise-reduction mode is also available to help comply with nighttime and weekend neighbourhood noise restrictions. Acoustic packages deliver amongst the quietest operations in the market adhering to noise level regulations while improving further the efficiency.

Next-generation integrated controls offer a simple user interface that is standard on every Sintesis chiller, delivering efficiency and performance advantages. The Tracer AdaptiView chiller controls feature a 7-inch colour touch-screen display for at-a-glance status and intuitive navigation for simplified operation.

Proven control strategies such as integrated temperature and flow logic respond to a wide variety of conditions and maintain reliable, efficient chiller operation. Adaptive Control keeps the chiller working efficiently in extreme conditions — even under a building automation system failure — for continued reliable operation when it is needed most.  The control set up of Sintesis chillers offers a unique ice storage feature for cooling during peak demand.

In Europe and the Middle East, the new Trane Sintesis chillers are available in sizes of 245 up to 450 (cooling capacities from 300 to 1600kW). The chillers reach 1.6MW of cooling capacity at Eurovent rated points and supplement the original 090 to 205 sizes introduced by Trane in 2014.

In North and Latin America, Sintesis chillers (115–500 tons) will be available throughout the year, starting with the 115- to 215-ton models available now, and followed by the 230- to 500-ton models in late 2015.
