Reheat system
WebNov 26, 2024 · The design of heating, ventilation and air conditioning (HVAC) systems has a significant impact on both, and working with a qualified engineering firm has a positive impact on the final outcome. A key decision in HVAC design is selecting an adequate air-handling configuration: constant air volume (CAV) or variable air volume (VAV). WebConstant air volume (CAV) is a type of heating, ventilating, and air-conditioning system. In a simple CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space. Most CAV systems are small, and serve a …
