🔍 Key Concepts

• Carefully trace the piping arrangement in figure C and compare it with figures A and B. • Note the difference between series flow through loads versus parallel branches from supply and return mains. • Consider whether the boiler and chiller are arranged so that both can circulate water at the same time in figure C.

💭 Think About

• In figure C, does the water have to pass through Load 1 before it reaches Load 2, or does each load connect directly to the main supply and return lines? How would that affect the temperature of the water entering each load? • Look at how the boiler and chiller are tied into the loop in figure C. Is there anything in the piping that would prevent hot and chilled water systems from being operated together? • Which statements (B or C) would be more typical of a system where loads are in strict series, and which would be less true for loads piped in parallel?

✅ Before You Answer

• Verify which way flow actually goes through the distribution piping and loads in figure C. • Check whether each terminal unit sees the same supply temperature or a temperature changed by previous loads. • Confirm if there is any valve or piping feature in figure C that forces you to choose either heating or cooling, rather than allowing both.

What statement is true concerning figure "C" of the illustrated hydronic heating/cooling systems? See illustration GS-RA-44.

The chilled water circulating system and the hot water circulating systems may be placed into operation simultaneously.

During the cooling season, in the direction of flow, each terminal unit receives progressively warmer water supplied to its inlet.

During the heating season, in the direction of flow, each terminal unit receives progressively cooler water supplied to its inlet.

The chilled water circulating system and the hot water circulating systems may NOT be placed into operation simultaneously.
