Description

<p> The heat exchanger of air conditioners installed in windy seaside areas may suffer from corrosion. This corrosion reduces the heat transfer coefficient of the heat exchanger and reduces the performance of the air conditioner. It also damages the refrigerant pipes and may cause refrigerant leakage. In this study, corrosion was produced on fin-tube heat exchangers by an accelerated corroding test with salt water mist. The corrosion level on the heat exchangers is the same as the damage in the area suffering from salt damage for 3-15 years. To estimate the heat transfer decrease from corrosion, the quantity of heat exchange between air and hot water in the refrigerant pipe of the corroded heat exchanger was measured. The overall heat transfer factor decreased by 48% with the corrosion, which level is same as the damage in an area suffering from salt damage for 15 years.</p>
