3.2.11. Economic and thermodynamic properties

• Should have high value of latent heat of vaporization
• Should have high thermal conductivity
• Should have high electrical resistance
• Should have low specific volume
• Should have low specific heat
• Should have low freezing point (than the maximum temperature of the refrigeration system)
• Should have low boiling temperature
• Should have low leakage tendency. Leakage should be detectable
• Above all the refrigerants should not be expensive
