Reheat is the addition of heat to previously cooled air. Reheat is used sometimes for humidity control, and sometimes for occupant comfort. The objective is to size it so that when the VAV system supplies its minimum air volume, the zone loads provide all reheat, either for humidity or comfort purposes.Click to see full answer. Subsequently, one may also ask, what is a reheat system quizlet?It’s a modification of the single zone system to provide zone or space control for areas of unequal loading, or to provide heating or cooling of perimeters areas with different areas. what is the purpose of a reheat coil? reheat coil. 1. In an air-conditioning system, a coil which heats air in the supply duct to control its temperature. 2. A coil which is heated to control the temperature of air being furnished to individual zones, 1. In this regard, what is a terminal reheat system? terminal reheat system. terminal reheat system. A type of air handling system commonly integrated with CAV and VAV systems that maintains comfort in a building by cooling the air at the air handling unit and then reheating the air near its point of use.What is VAV reheat?Variable air volume (VAV) with reheat systems provide conditioned air to each zone at a constant temperature, typically 55°F. A temperature sensor located in the space adjusts the damper to maintain the room temperature setting. When more dampers close, the duct system static pressure increases.
