How does moisture affect MVAC systems?

Moisture has a significant impact on MVAC (Motor Vehicle Air Conditioning) systems, primarily due to its potential to cause corrosion and the formation of acids. When moisture enters the system, it can mix with refrigerants and other components, leading to chemical reactions that create acids. These acids can corrode metal parts within the system, such as the compressor, evaporator, and other components, reducing the overall lifespan and reliability of the system.

Moreover, excess moisture can lead to the formation of ice in the expansion device, which can block the flow of refrigerant and severely impair the system’s efficiency. Understanding the detrimental effects of moisture is vital for maintaining the integrity and performance of MVAC systems, thus pointing to the critical need for ensuring proper moisture control and management.
