I DEAL PROPERTIES FOR A REFRIGERANT

These can be listed as

• High latent heat of vaporization

• High suction gas density

• Positive but not excessive pressures at evaporating and condensing conditions

• Critical temperature and triple point well outside the working range

• Chemically stable, compatible with construction materials and miscible with lubricants

• Non-corrosive, non-toxic and non-flammable

• High dielectric strength

• Environmentally friendly

• Low cost

Needless to say, no single fluid has all these properties, and the choice of fluid for any particular application will always be a compromise.
