Mark Mitchell is a former vehicle air conditioning installer and repairer in the days before factory air was fitted to most vehicles, and he is now considered one of the country's most knowledgeable and passionate students of the physical properties of heat, energy, and thermal efficiencies. His expertise is valued by many authorities, among them the Australian Government who sent him to Brussels a few years ago to represent Australia at a global forum on mobile air conditioning and refrigeration. In late 2014, Mark represented Carrier at a summit in London that brought together leading world experts to consider the impact of refrigeration and transport on global food wastage.

Mark sits on boards dealing with refrigerants and their properties, including the award winning refrigerant stewardship authority, Refrigerant Reclaim Australia.  He was foundation president of VASA, formed by mobile air conditioning specialists more than 25 years ago. VASA's mission was to steer technical training and government understanding of the growing vehicle air conditioning sector.

Mark played a big role in the early development of the current national refrigerant handling licensing and authorization scheme aimed at preventing environmental damage from accidental or indiscriminate release of ozone destroying or greenhouse gases.

Among his many achievements with SuperTest, an HVAC and refrigeration testing center, has been his ability to demonstrate to the transport refrigeration industry that it can test a transport refrigeration trailer in a controlled booth and determine the K value of the trailer – an equation involving calculation of the amount of heat that will escape into the body over a given time and over a certain area. Once the heat rejection or heat flowing capabilities of the trailer are known, the correct size of the refrigeration that goes on that trailer can be determined with some degree of accuracy. The SuperTest philosophy is to help the industry find out more about their equipment and processes so that they can achieve cost efficiencies.
