Airedale launch ‘first to market’ TurboChill free cooling chillers using low GWP refrigerant
Airedale International Air Conditioning, believes it will be the first to launch a production range of high performance free cooling chillers using the low global warming potential (GWP) refrigerant R1234ze.
In recognition of its low global warming impact, the TurboChill free cooling chiller (TCF) with R1234ze automatically receives two BREEAM points, according to the company. In contrast, R134a TurboChill TCC and TCF variants receive one point for their Direct Effect Life Cycle (DELC) CO2 equivalent emissions of ≤1000 kgCO2e/kW cooling capacity and a further point for leak detection and automatic shutdown and pump-down of refrigerant.
Energy efficiency is a key design criterion across Airedale’s entire range of chillers, precision air conditioning and IT cooling systems which offer industry-leading part-load performance and energy efficiency for footprint. All models in the TurboChill range have been designed to meet the criteria established by the Energy Technology List and selected models* qualify for a 100% first year capital allowance under the Government’s Enhanced Capital Allowance (ECA) scheme. (*Accreditation of remaining models is pending).
The TurboChill FreeCool (TCF) is said to offer twice as much free cooling as a thermosiphon free cooling system and can deliver free cooling for up to 95% of the year. By constant monitoring of temperature differences, Airedale’s controlsoftware permits concurrent free cooling - a mixture of free cooling and mechanical cooling – switching on the mechanically-driven compressor only when extra cooling is required.
The R1234ze TurboChill free cooling (TCF) range will be released at the end of 2013 alongside a 1,600kW dual circuit TurboChill™ incorporating R134a, delivering redundancy back-up and quicker compressor start-up to full load capacity in a 500kW higher capacity model.
