Méthodes de prévention de la corrosion dans les systèmes indirects utilisant des frigoporteurs.

Corrosion prevention methods in indirect systems with secondary refrigerants.



Secondary refrigerants are aqueous solutions of organic or inorganic salts used in indirect refrigeration systems to transfer heat. Water is known for its corrosive character and secondary refrigerants based on aqueous solutions have the same tendency. The most important corrosion factors are: type of secondary refrigerant, fluid velocity, pH, concentration, temperature, dissolved oxygen and scaling behaviour. Nevertheless, it is possible to minimize corrosion problems. There are several aspects which need to be taken into the consideration while working with the secondary refrigerants e.g. design of system, selection of secondary refrigerant, corrosion inhibitors and compatible materials used in the installation. The methods of system cleaning, refrigerant charging and deaeration procedures are also extremely important. The purpose of this paper is to present corrosion problems and provide a list important aspects related to designing, preparing and maintaining of indirect systems. Moreover, it introduces the traditional and alternative methods of corrosion protection of indirect systems with secondary refrigerants.
