Airedale unveils ultra-efficient TurboChill
Story
Leading air conditioning manufacturer Airedale has launched its most efficient chiller yet, the TurboChill air-cooled, high capacity chiller. Central to the design of the TurboChill and key to its superior performance, are revolutionary centrifugal Turbocor compressors optimised with a raft of cutting-edge components. Brilliantly engineered, using Airedale’s vast expertise in cooling technology, the TurboChill minimises environmental impact by lifting efficiency to new heights and pushing down sound levels.
The TurboChill’s ‘seasonal efficiency’ ESEER values of up to 5.7 are virtually 50% higher than those of a traditional screw chiller and unparalleled for an air cooled chiller, greatly reducing operational costs and carbon emissions. The Turbocor compressor itself has an EER of up to 8.0 at part load.
The TurboChill’s intelligent, self-optimising compressors present near silent operation and allow ultra efficient variable speed control, thereby using substantially less power at part load and giving accurate setpoint control and exact capacity match. The TurboChill offers a modular capacity range of 500 – 1100kW and is optimised for R134a.
Featuring the very latest low speed sickle-bladed fans with EC motors, the TurboChill offers two sound ranges – Quiet (SQ) and Super Quiet (SSQ). The friction-free operation of the compressor presents virtually no vibration, enabling the compressor to run in a smooth sound spectrum, and as much as 5 -7 dBA quieter than a similar sized screw compressor.
A very low starting current of just 2A is built into the TurboChill compressor’s variable speed control, removing the transient starting ‘spikes’ of high peak currents normally associated with screw chillers of this capacity. It also means that electrical supply components need not be oversized on site.
The compressor’s reliable, oil-free technology enables the TurboChill to operate up to four compressors on a single circuit, intelligently managed by AireTronix controls and significantly increasing part load efficiencies. With fewer moving parts within the compressor there is no operational ‘wear and tear’ avoiding costly bearing replacement.
The TurboChill’s single pass evaporator offers the same excellent performance and efficiencies as a flooded evaporator but with much lower refrigerant charge, facilitating F Gas compliance. Optimised heat exchange and oil-free operation allow a reduced compression ratio and increased EERs of up to 10%.
Due to its superior energy efficient performance, the TurboChill meets the criteria of Class A Eurovent rating and is included on the Energy Technology List thereby qualifying for the Carbon Trust ECA (Enhanced Capital Allowance) Scheme. Log onto www.eca.gov.uk for more details.
