Close control air conditioners

Overview

Close control air conditioners are used where temperature and humidity need to be monitored and maintained within narrow limits. Applications include computer rooms, data processing units, telecommunication facilities and industrial processing areas.

What products are covered?

Products covered by this Determination include close control air conditioners where temperature and humidity are required to be monitored and maintained within narrow limits, for example, in computer rooms, data processing units, telecommunications facilities and other industrial process areas.

The Determination only covers products that are unitary air conditioners designed for high sensible heat ratio applications, and that are capable of maintaining close control of both temperature and humidity. Products must consist of one or more factory-made assemblies, which must include a compressor, a direct expansion evaporator, an air-moving device and air-filtering devices, and may include a condenser, a humidifier or a reheating function.

Refer to section 5 of the Determination for more details.

The following products are not covered by this Determination.

• Ducted or non-ducted split systems.
• Ducted packaged units.
• Multi-split systems (for example, those having more than one indoor unit with an independent control for each indoor unit).
• Evaporative coolers or any other cooling system that are not of the vapour compression type.
• Ground water sourced or ground loop sourced heat-pumps.
• Unbalanced air conditioners and spot coolers.
• Commercial chillers used in commercial buildings to provide chilled water for space-cooling equipment.
• Close coupled row based cooling units.
