Carrier says its new range of variable-speed screw chillers achieves exceptional levels of seasonal efficiency.
The AquaForce Vision 30KAV with Greenspeed intelligence, with a first phase covering cooling capacities from 500 kW up to 1100 kW, is equipped with variable-speed screw compressors and variable-speed fans – AC as standard and EC as an option – as well as optional variable-speed pumps.
It automatically adjusts the cooling capacity and water flow to match the needs of the building or process load variations. The result is optimal operation at both full load and part load. This new range of chillers has a SEER of up to 5.5 in cooling mode, and an Energy Efficiency Ratio (EER) of up to 3.49 at full load. 30KAV offers energy efficiency up to 40% higher than the 30GX range with the same footprint.
