From 12-14 April 2010, the Sydney Convention and Exhibition Centre opens its doors for all stakeholders in natural refrigerants, inviting them to discuss the state of play and explore the latest research in the field. Those who register until the 28 February can still get a 300-400 dollar early bird reduction.

“Natural refrigerants – Real alternatives” is the motto of the event organised by the International Institute of Refrigeration and Australian Institute of Refrigeration, Air Conditioning and Heating. The conference will present latest research as well as applications using natural refrigerants in heat pump, air conditioning and refrigeration systems and offer ample opportunity to discuss the consequences of recent policy developments on the sector.

The main topics on the agenda are:

• Natural primary refrigerants 
• Secondary coolants and ice slurries 
• Sorption systems
• Non conventional refrigeration systems
• Heat transfer and fluid flow 
• Energy use and energy efficiency of natural working fluid systems

Submitted papers

The scientific and technical discussions in the Conference will treat a broad range of natural refrigerants. Of particular interest in regards to ammonia are however the following papers:

• “Ammonia and CO₂ combined package systems for commercial and industrial applications” by Andrey Andrusenko (AU)
• “Automatic multi-objective optimisation based shape design: Application to design the evaporator for an Ammonia low capacity refrigerator” by A. Mosavi (HU)
• “Groundwater system with ammonia heat pumps saves 70% of energy” by Henrik Winther (DK)
• “Elimination of wet return lines in ammonia systems” by Anders Mønsted (DK)
• “Air cooled chillers with ammonia” by Andy Pearson (UK)

The first conference in this kind on the Southern hemisphere will reunite researchers, system designers, HVAC&R engineers and consultants, equipment suppliers, government and policy makers, carbon reduction specialists, technology and operations managers and many more. The Conference offers a great opportunity to network and to get up-to-date about the latest ongoings in a very specialised yet promising sector.

About Gustav Lorentzen

The conference is named in honour of Norwegian Scientist and engineer Gustav Lorentzen who rediscovered how CO₂ could be used as a refrigerant in a simple and efficient way in heating and cooling applications.
