The use of natural refrigerants such as hydrocarbons (R-600a, R-290 and R-1270) is now widely promoted as a long term replacement for many of the fluorinated hydrocarbons such as hydrofluorocarbons (HFCs) used as refrigerants in the refrigeration and air-conditioning sector.  These HFCs are known to have very high ozone depleting and global warming potentials (ODP and GWP) and contribute to ozone layer depletion, global warming and climate change.

At the recently held 28th Meeting of the Parties to the Montreal Protocol in November 2016, Parties adopted to the Kigali Amendment to the Montreal Protocol and agreed to address the phase-out of production and consumption of high GWP HFCs.

Hydrocarbons have long being used as refrigerants are widely known for their zero ozone depleting potential and very negligible global warming potential.  They also have the added advantage as been more energy efficient that the HFCs than are currently in use.  Other advantages include smaller refrigerant quantities needed, greater thermodynamic properties and lower operating pressures that can extend the life of the compressors.

This new air-conditioning system is installed at the refrigeration and air-conditioning laboratory at TAMCC and would be used for training of students and technicians in hydrocarbon technology in the air-conditioning sector. Efforts are already underway by the National Ozone Unit to bring in another thirty (30) such units into Grenada to be used for demonstration purposes.
