Question 1 of 27070

A reheater, as used in an air conditioning system, is designed to control what temperature?

🔍 Key Concepts

• Reheat coils in HVAC (heating, ventilation, and air conditioning) systems and where they are placed in the air stream • Difference between room air temperature and supply/primary air temperature • How air is cooled below room conditions for dehumidification, then brought back up with reheat

💭 Think About

• Think about what happens to the air right after it leaves the cooling coil: is it usually colder or warmer than the room needs? Why would you then add heat? • Which temperature does the reheat device most directly affect: the water in the coil, the moisture content of the air, the temperature of the supply air entering the room, or the final room temperature? • In variable air volume (VAV) or central AC systems, what part of the system is adjusted when you want comfortable supply air to the space without changing how much moisture you remove?

✅ Before You Answer

• Identify where in the system the reheater is located: on the air side or the water side? • Decide whether a reheater’s job is to control moisture content (dew point) or mainly temperature of a specific air stream. • Ask: Does the reheater control the temperature of the room itself, or the conditioned air being delivered to that room?
