With no power on site, generators were also provided to run the chillers and air handlers.

The redevelopment project is due for completion in September 2015.

Key to better indoor air quality is the use of high volumes of outdoor air.

The first stage involved retrofitting a direct drive EC plug fan in place of the belt driven dual inlet backward curved blower on a single floor.

The project sets the bar for environmental performance at a community level.

The audit recommended replaced four piston compressors with a thermorefrigerating pump.

Each module includes two twin frame M10BW plate heat exchangers for evaporating and condensing, and a U-Turn liquid separator.

Heat wheels recycle 90 per cent of waste heat.

The cooling capacity varied between 450 and 1050 kW so there was plenty of ice.

What would a HVAC outage cost your organisation for an hour, a day, or week?

It will feature custom environmental control units with dual, redundant refrigeration circuits.

The previous system was too old and too expensive to repair.

Hanbell screw compressors with solenoid staged capacity control were used.

The ventilator extracts damp air from domestic sub-floors, helping to protect the house from mould and fungi growth, termites and odours.

Chillers were pre-ordered to ensure timely delivery and selection of the optimum combination of capital cost, reliability and energy efficiency.

Only 54kg of Oz-Chill 22a was needed to replace the previous 123kg of R22.
