The National Ozone Unit continued its training of technicians in hydrocarbon refrigerant. Technicians in Tobago were exposed to the basics of hydrocarbon refrigerant as well as participated in a practical session doing a retrofit of a compressor on an R 290 Unit. The following types of hydrocarbons are commonly used as refrigerants:
R290 Propane
R600a Isobutane
R1270 Propylene
A number of other hydrocarbons, such as blends containing ethane, propane or butane, are also used as refrigerants.
