Refrigerant Characteristics
• Hydrocarbon refrigerants :– Asphyxiant
– Flammable
– Low Global Warming Potential
– High efficiency
– Cheap
– Low Compression ratio (high suction, low discharge pressures)
– High heat transfer in heat exchangers
– Reduced system pressure losses (lower refrigerant density and viscosity)
– Non Stenched (no smell)

Practical Assessments
• Recovery of Flammable Refrigerants.• Partial evacuation/purging with inert gas.• Ensuring flammability limits are not reached.• Brazing of system components.• Pressure strength/tightness testing.• Evacuation/De-Hydration.• Charging of systems.• Leak testing

HC Recovery
• The area must be well ventilated• No source of ignition within 3m• Forced air ventilation is recommended,
using a EX rated fan motor with
a 5m cable to ensure switching
is provided outside of 3m zone.• A HC leak detector must be used
throughout the process
(cannot have a zero function
must alarm at 20% LFL)
Fill system with OFN
