Thus, the no control effect (i.e., control delay) until such time as themixing ratio of the supply air can be adjusted easily — setpoint temperature respectively rises (or falls) above (orwithout any control delay, and in much more stable fashion below) the actual temperature. This problem applies to— by modulating the cooling and (where fitted) heating both temperature- and humidity-control loops.coil control valves. As the supply air is brought close to This is illustrated in Fig. 4, which shows the effect ofsaturation, there should always be some re-heat in order to having a supply-duct temperature setpoint of 14°C (57°F),control temperature independent of humidity control. This when the actual supply-duct temperature at 17°C (63°C)sounds like it might waste energy; however, heat-recoverycoils are fitted to extract heat from the room return air,and this is used as the first stage of re-heat.
