🔍 Key Concepts

• Figure A is a single-pipe, series loop hydronic system (one main, loads tapped in line). • In a series loop, the same water passes through Load 1 then Load 2, picking up or giving off heat as it goes. • During the cooling season, the water entering the loop is at its coldest and then absorbs heat from each terminal unit in turn.

💭 Think About

• Trace the direction of water flow in Figure A and ask: after passing through Load 1, is the water going to Load 2 colder, warmer, or the same as when it entered Load 1 during cooling? • If each terminal unit removes heat from its room air, what must happen to the water temperature as it leaves that unit? • Compare this behavior to what would happen in a parallel system where each load has its own branch off the main — would the water temperature to each load be identical there?

✅ Before You Answer

• Be sure Figure A is recognized as series (one continuous loop), not parallel branches. • Focus only on the cooling season for this question; ignore what happens in heating for now when comparing the options. • Check which option correctly describes how the supply water temperature changes from Load 1 to Load 2 along the direction of flow in a series cooling loop.

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

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

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 warmer water supplied to its inlet.

Regardless of the season, in the direction of flow, each terminal unit receives the same temperature water supplied to its inlet.
