What might excessive moisture in a system lead to during evacuation?

Improved efficiency
Longer evacuation time
Less risk of contamination
Enhanced cooling performance

The correct answer is: Longer evacuation time

Excessive moisture in a system can significantly impact the evacuation process and lead to longer evacuation times. When moisture is present, it can condense and form liquid water, which can affect the efficiency of the vacuum pump and delay the removal of air and non-condensables from the system. The presence of moisture increases the volume of gases that need to be evacuated, extending the time needed to reach the desired vacuum level. Additionally, moisture may cause the system to be less efficient in functioning, as it can lead to corrosion and other issues once the system is recharged. Therefore, achieving a proper evacuation becomes more complex and time-consuming when excessive moisture is involved.
