“…In this study, the main focus is heat exchangers as the condenser and absorber are sea water cooled. There has been some studies on heat exchanger corrosion issues [41]. One of the solution is the anticorrosion coasting, as investigated by L. Fedrizzi (2008) [42].…”

“…Not only does heat transfer have an influence on the corrosion process, but corrosion can also negatively affect the thermohydraulic performance of the heat exchanger (Edwards, 2008;Mousavian et al, 2011). This is illustrated by the study of Zhao et al (2012), where the effect of corrosion on the performance of finand-tube heat exchangers was investigated. The heat exchangers were subject to accelerated corrosion by keeping them in a standardised salt spray chamber for 48 or 96 h. The performance after being corroded was evaluated based on the cooling capacity, the heat transfer coefficient, the thermal resistance, and the air-side pressure drop, and compared to the performance before the test.…”

“…In the study by Zhao et al (2012), the decrease in heat transfer is attributed to a layer of corrosion products that formed on the fins (mainly Al 2 O 3 , aggravated by the galvanic cell that exists between the aluminium fins and the copper tubes). This additional thermal resistance caused by corrosion products also occurs in other heat exchangers constructed from different materials (Turissini et al, 1997;Ranjbar, 2010;Yang et al, 2012).…”

In many industries and processes, heat exchangers are of vital importance as they are used to transfer heat from one fluid to another. These fluids can be corrosive to heat exchangers, which are usually made of metallic materials. This paper illustrates that corrosion is an important problem in the operation of heat exchangers in many environments, for which no straightforward answer exists. Corrosion failures of heat exchangers are common, and corrosion often involves high maintenance or repair costs. In this review, an overview is given of what is known on corrosion in heat exchangers. The different types of corrosion encountered in heat exchangers and the susceptible places in the devices are discussed first. This is combined with an overview of failure analyses for each type of corrosion. Next, the effect of heat transfer on corrosion and the influence of corrosion on the thermohydraulic performances are discussed. Finally, the prevention and control of corrosion is tackled. Prevention goes from general design considerations and operation guidelines to the use of cathodic and anodic protection.

“…It allows to imitate the corrosive phenomena occurring during exploitation of automotive heat exchangers in a different conditions. The test in the salt fog is frequently used to control the process of making heat exchangers, including brazing which is the main operation affecting the final quality of these products [10][11][12][13][14][15][16].The authors are convinced that the one of main causes of material corrosion deficits is aggressive environment which contains sodium chlorides. In scientific articles the impact on chloride corrosion in automotive heat exchangers was not discussed sufficiently.…”

A B S T R A C TIn the work, the most important factors which influence on the exploitative durability of heat exchangers are classified. Particular attention was paid to the compounds of sodium chloride used in the winter season for road maintenance. In order to determine their impact on automotive heat exchanger corrosion resistance, a test of heaters in a salt chamber which imitates the conditions of their work was realized. It also allows to verify the durability of these products. To evaluate the corrosion changes, observation with the use of light microscopy and scanning microscopy SEM were made supplemented with microanalysis of chemical composition by EDS spectroscopy method. Critical areas in the heat exchangers which are mostly exposed to damage including the formation of local corrosion pits were located and analyzed.
