Cylindrical condensers boost efficiency
ITALY: Geoclima’s new range of air cooled chillers is said to achieve even higher efficiencies thanks to the incorporation of special cylindrical condensers and cascade flooded evaporators.
The new Circlemiser series sets itself as the most efficient air cooled chiller series available on the market today. Its EER of 4.35 represents an increase in efficiency up to 15% compared to high efficient technologies like Geoclima’s existing high efficiency chillers, the Turbomiser.
The special cylindrical condensers have a 45% greater heat exchange surface compared to traditional condensers, while maintaining the same footprint, it is said. This increased heat exchanger capacity makes it possible to reduce condensing temperature as well as approach temperature.
In addition to cylindrical condensers, Circlemiser chillers are also equipped with cascade flooded evaporators, which lead to the reduction of the ΔT between evaporation temperature and outlet temperature of the fluid. The cascade arrangement of the evaporators increases the evaporation temperature and, at the same time, reduces energy consumption. Using this type of evaporator Geoclima has been able to further increase efficiency across the range of the Turbomiser air cooled chillers.
The new Circlemiser series is available with R134a or HFO-1234ze refrigerants.
