What is the minimum condensate pipe diameter required for up to 20 tons of refrigeration?

• A. 1/2 inch
• B. 3/4 inch
• C. 1 inch
• D. 1 1/4 inch

Answer: (B)

For systems with up to 20 tons of refrigeration, the minimum condensate pipe diameter required is 3/4 inch. This specification is set to ensure that the condensate can drain effectively and that there is adequate capacity to handle the anticipated flow. The 3/4 inch diameter strikes a balance between sufficient drainage capability and maintaining a manageable pipe size within the plumbing system. A smaller diameter may lead to drainage issues, such as clogging or backup, particularly if the condensate flow is substantial during operation. Thus, using a 3/4 inch pipe helps to accommodate the volume of condensate produced without risking operational problems.
