8. Refrigerant selection criteria

In addition to economic criteria, the choice of a refrigerant for a given application must take into account a number of other criteria, the importance of which varies according to the market in question:

• toxicity criteria are essential for food applications;

• Corrosivity criteria are studied differently depending on whether the installation is new and the choice of materials is left to the designer's discretion, or whether the installation is old and the materials are imposed;

• the weight of regulations is obviously very different depending on whether you're equipping an industrial site or a facility open to the public.
