Organised by the International Institute of Refrigeration (IIR) in cooperation with the Chinese Association of Refrigeration (CAR) in Hangzhou, China on 31 August – 2 September 2014, the Gustav Lorentzen (GL2014) conference updated participants on the most recent progress related to the use of natural working fluids. As in previous years, it appears that the most active area of natural refrigerant research continues to be CO2, which is being applied to an increasing extent by the refrigeration and heat pump industry around the world.

CO2 research papers presented at GL 2014

  • Latest research on CO2 refrigeration technologies for warm climates
  • CO2 more efficient than HFCs in data centre cooling and glass door merchandisers
  • How to improve CO2 efficiency in commercial refrigeration
  • DTI at Gustav Lorentzen 2014: can ice storage and Vortex Flow Sensors improve CO2 system efficiency?
  • GL2014 CO2 heat pumps session: how to improve system efficiency and performance in residential applications
