Airedale develops more efficient close-control air conditioning range

Airedale

Airedale’s latest generation of precision cooling solutions for data centres and computer rooms are said to significantly reduce energy consumption and maximise uptime.

The SmartCool range has a host of energy-saving design features. They include direct-drive AC range with EC motor options, ‘blow-through’ design and efficient A-frame coil. Up to eight stages of DX cooling and optional inverter-driven compressors contribute to a 30% increase in system efficiency compared with Airedale’s previous generation of close-control units.

There is a choice of seven systems. DX systems use R410A and have cooling capacities from 60 to 130 kW for air or water cooling. Chilled-water units have cooling capacities from 60 to 150 kW. DualCool options offer built-in redundancy, with both DX and chilled water in the same case, and a free-cooling variant. SmartCool can be matched with Airedale remote condensers and free-cooling chiller.

The glycol free-cooling DualCool variant uses 46% less energy than the equivalent air-cooled DX system, leading to large savings in electricity costs and carbon-dioxide emissions. Units are also smaller, with 13% more cooling per square metre than previously achieved by Airedale close-control units.

SmartCool’s control logic, dual power and DualCool options within the case are designed to meet the N+1 and 2N redundancy requirements of critical data-centre applications.

Speed-controllable direct-drive AC fans have optional EC fan technology for greater efficiency and allow for automatic adjustment of air volume when faced with variable system resistance.

Optional inverter-driven compressors offer fully modulated cooling down to 20%, enhanced part-load efficiency and a starting current only 10% that of a traditional fixed-speed scroll compressor.
