Carrier AquaSnap scroll chiller range is now available with R-32 refrigerant, which improves performance and reduces direct greenhouse gas emissions by up to 80%, 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% – allows for an exceptional 80% 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. 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,” said Didier Genois, Vice President, Carrier HVAC-Commercial, Europe. “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.
