CHWR corresponds to which term?

• A. Chilled Water Return
• B. Chilled Water Reserve
• C. Condenser Water Return
• D. Cooling Water Routing

Answer: (C)

Understanding how CHWR labels the condenser water path helps you read plant drawings correctly. In a cooling plant, there are two main water loops: condenser water and chilled water. Each loop has a supply and a return line. The abbreviation CHWR is used to denote the return leg of the condenser water loop—the water that has circulated through the condenser, dumped its heat, and is returning to the cooling source to be cooled again. That alignment makes Condenser Water Return the best fit for what CHWR represents in this context. The other options refer to different parts of the system (like chilled water concepts or unrelated terms), which don’t match the labeling convention used here.
