On low-pressure chillers, moisture most frequently enters the refrigerant system through:

A. Leaks from the charging service valve.
B. Tube leaks in the evaporator.
C. Air leaks in the rupture disc assembly.
D. Leaks from areas with gaskets or fittings.

Answer :

Final answer:

Moisture most frequently enters the refrigerant system in low-pressure chillers through leaks from areas with gaskets or fittings.


Explanation:

On low-pressure chillers, moisture most frequently enters the refrigerant system through leaks from areas with gaskets or fittings. These leaks can occur due to faulty gaskets or improperly installed fittings. When these leaks happen, moisture from the surrounding air can enter the system and contaminate the refrigerant. It is important to regularly check and maintain the gaskets and fittings to prevent moisture ingress.
