Question 1 of 27070

What type of HVAC system is characterized by a having a split supply air stream, with one for cold air and the other for hot air?

🔍 Key Concepts

• Supply air streams in HVAC systems and how many separate ducts they use • Difference between hot deck and cold deck arrangements • How temperature control is achieved at the space: by mixing air vs reheating it

💭 Think About

• For each system type listed, picture how many main supply ducts leave the air handling unit and what temperature air each duct carries • Ask yourself: does this system mix hot and cold air at the terminal, or does it cool first and then reheat, or just vary the air volume? • Consider which option specifically needs two separate supplies from the air handler, one predominantly hot and one predominantly cold

✅ Before You Answer

• Verify which option is defined by having two separate main ducts from a central unit • Check which system depends on mixing hot and cold air streams near the spaces being served • Eliminate systems where there is only one primary supply duct and temperature is controlled by volume or reheat instead of dual streams
