In an AC system, a dry cooling coil bears only the sensible heat load and not the latent heat load. The chilled water inlet temperature of the coil typically exceeds 13°C, which is above the dew point temperature of indoor air. This prevents the coil from producing condensed water and allows it to operate under dry conditions, hence the name “dry coil.”
