Carrier AquaSnap scroll chiller range is now available with R-32 refrigerant.

The low-GWP refrigerant improves performance and reduces direct greenhouse gas emissions by up to 80 per cent, compared to the previous range using R-410A refrigerant.

The innovative air-cooled range meets requirements for the European F-Gas phase-down of HFC refrigerants and Ecodesign requirements for 2021.

Carrier selected R-32 refrigerant, which has a low global warming potential (GWP) of 675, for use in commercial scroll chiller ranges.

R-32 has a GWP that is two thirds less than the GWP of the current R-410A version and this change, combined with a significant system refrigerant charge reduction - up to 30 per cent - allows for an exceptional 80 per cent reduction in direct greenhouse gas emissions.

The AquaSnap range reaches an outstanding Seasonal Energy Efficiency Ratio (SEER12/7) of up to 5.33 and a Seasonal Coefficient of Performance (SCOP) of up to 3.77.

Carrier’s European vice president of commercial HVAC, Didier Genois, said the range covers capacities from 40 kW to 940 kW.

"Carrier's AquaSnap range with R-32 refrigerant allows our customers to anticipate compliance to Ecodesign 2021 requirements while supporting the next phase down steps of the European F-Gas regulation for HFC," Genois said.

"The range also provides customers with best-in-class performance in heating and cooling conditions."

The AquaSnap with R-32 refrigerant can meet the needs of a wide scope of applications. The range covers an extended operating map, up to 48 degrees Celsius outdoor air temperature, and features Carrier's best-in class technologies for maximum efficiency in all conditions, including:

- Multiple scroll compressors able to match load requirements.

- Brazed asymmetric plate heat exchangers with true dual-circuit design for high performance in both full- and partial-load conditions.

- Smart energy monitoring function providing real time capacity provided and energy consumption measurement.

- Greenspeed intelligence on premium versions: variable-speed fans and variable-speed pumps.
