What must be done to prevent corrosion in a vapor-cycle cooling system?

To prevent corrosion in a vapor-cycle cooling system, monitoring and controlling moisture levels is crucial. Moisture can enter the system through leaks or inadequate sealing, and when it combines with refrigerants, it can lead to the formation of acidic byproducts. These acids contribute to the corrosion of metal components within the system, such as the evaporator, condenser, and piping. By actively monitoring the moisture content in the system and ensuring it stays at low levels, you significantly reduce the risk of corrosion and extend the life of the cooling system. This proactive approach is essential for maintaining the integrity and efficiency of the vapor-cycle cooling system.

While changing refrigerant regularly, utilizing synthetic oils, and conducting high-pressure testing can have their benefits, they do not directly address the prevention of corrosion caused by moisture presence in the system.
