Users can enjoy years of reduced energy bills with the free cooling delivered by the new Climaflakt KCAG and KCDC range of air-cooled chillers from Fläkt Woods. These offer capacities from 20 kW to 150 kW, with both air-cooled in cooling-only and heat pump models. The units, fully integrated with Fläkt Woods chiller, air handling unit and chilled beam ranges, complement the KCCC range of R410A chillers which offers 150 kW to 900 kW capacities.
As well as using the non-ozone-depleting R410A refrigerant, KCAG and KCDC chillers feature multi-scroll compressors and increased heat exchanger surface area when operating at part loads. Together, these enable the chillers to achieve high EERs (Energy Efficiency Ratios) and ESEERs (European Seasonal Energy Efficiency Ratios), with up to 35% energy savings. In addition, the new chillers offer low noise levels, and easy installation and maintenance. They are available with microprocessor control, electronic expansion valves, three low-noise versions and ‘plug and pump’ hydraulic pump packs. All are offered as heat pump or free cooling models.
Linden Shuttleworth, Fläkt Woods UK Sales Manager, Fläkt System Products, said: “The key benefit of the new chillers is continuing cost savings throughout an air handling system’s lifetime. Once installed, KCAG and KCDC chillers can reduce a user’s energy bills day after day for the next ten years and longer. If there are few genuinely ‘free’ things in life, free cooling is certainly one of them.”
Free cooling is delivered when ambient temperature is low enough to permit a chiller to offer chilled water at no additional energy cost. It features compressors, condensers and evaporators, but also includes a dry cooler circuit. Even when ambient temperature rises, it will only introduce the operation of single compressors initially, giving simultaneous operation. Maximum impact is normally achieved between October and March, depending upon the prevailing climate.
A key design innovation is the use of more sophisticated microprocessor controls, enabling more precise operation of compressors based on the cooling demand. It both minimises the number of compressor starts and balances these between individual compressors for prolonged service life. Electronic expansion valves, optimising the superheat in every load condition, ensure improved compressor operating conditions through low discharge temperatures and preventing liquid return to the compressors
