WebJun 14, 2024 · Because the delta T achieved at a coil is a function of its heat-transfer surface, it follows that maximizing the delta T means maximizing the surface area. A cooling coil’s surface area is based on the number of rows, fin spacing, and the face area of the cooling coil. Too many rows or too tight of fin spacing can have negative impacts. WebThe basic function of the AHU is to take in outside air, re-condition it and supply it as fresh air to a building. All exhaust air is removed, which creates an acceptable indoor air quality. Depending on the required temperature of the re-conditioned air, the fresh air is either heated by a recovery unit or heating coil or cooled by a cooling coil.
