asymmetric channels are used not only for their e ciency but to reduce pressure drop and minimise the risk of fouling on the water side. Their true dual-circuit design also assists performance in both full and part-load conditions. To provide enhanced resilience, chillers use multiple stage compressors operating in two independent refrigeration circuits. This enables them to continue operating in the unlikely event of a compressor failing. It also limits the risk of refrigerant leakage in the case of accidental damage. Overall, as a result of system design improvements and careful component selection, the refrigerant carbon footprint of our commercial scroll chillers and heat pumps operating on R-32 has been reduced by up to 80%. This reflects the refrigerant’s lower GWP and reduction in charge compared to the previous generation using R-410A. In terms of energy e ciency, the chillers achieve an outstanding Seasonal Energy E ciency Ratio (SEER 12/7) of up to 5.33 for cooling, and a Seasonal Coe cient of Performance (SCOP) of up to 3.77 for heating. This exceeds Ecodesign 2021 requirements by some 20%. As a result, use of Carrier R-32 chillers and heat pumps attracts two BREEAM points when installed in environmentally assessed buildings. This enables end users to achieve the highest environmental standards in use today. In summary, Carrier has gone back to the drawing board and taken time to research and test how best to harness the properties of this new refrigerant, and developed fully optimised systems that deliver the best possible performance. The result is one of the most energy e cient and reliable ranges of R32-based chillers and heat pumps available. AquaSnap units save energy, cut running costs, reduce building carbon emissions, help protect the environment and, due to their resilience, ensure continuity of cooling for buildings and critical process applications. And they are available in capacities from 40 to 940kW (up to 550kW for heat pumps), which we believe is the widest Eurovent- certified range currently on the market.
