The Innovation
The new twin-coil system is the fifth and last of a number of air conditioning innovations developed by the late Dr Allan Shaw, formerly of The University of Adelaide.The innovation is aimed to reduce energy usage and enhance air conditioning performance.

An ongoing relationship forged through common interests resulted in control of the innovation being handed from the inventor to the commercialising company.The key shareholders of the commercialising company are the inventor ’s family and AIR CON SERVE Pty.Ltd.

The new system differs from conventional air conditioning processes in that,rather than drawing untreated outside air and then cooling it within the total air system,incoming outside air is pre-treated (dehumidified and cooled) by a separate,outside air coil before merging with inside air. Supply air is treated by the second coil,which belongs to the original conventional system.

The twin-coil system prevents the need to use energy twice to overcool and reheat air in order to maintain humidity in the occupied space,and monitors and adjusts humidity levels,providing better control.

University of South Australia report
The Anne and Gordon Samstag Museum of Art will be SA’s second largest public art gallery and a focal point of the Landmark building.
Among the museum’s many special requirements is an airconditioning system that delivers appropriate humidity and temperature levels for sensitive works of art, 24 hours a day.
The innovative South Australian designed Shaw Method of Air Conditioning (SMAC) system, which differs from conventional airconditioning systems by treating temperature and humidity loads separately, was chosen by Landmark’s architects to meet that challenge, following its successful installation in 2004 in the west wing of the Art Gallery of South Australia (AGSA)....
