Abstract
In a main controller for use in an air conditioner for controlling temperature/humidity of an intaken outside air, a controlling line setter (18) sets each of control lines (J.sub.1 -J.sub.5) on a psychrometric chart table (13), in which an aimed temperature/humidity line (Lo) is formed by connecting an upper limit state point (Ps) and a lower limit state point (Pw) of condition air from each of the outside air state points (G.sub.1 -G.sub.5) to the aimed temperature/humidity line (Lo). The controlling line (J.sub.1 -J.sub.5) is formed by connecting necessary lines selected from a main heating line (H.sub.L) showing the heating operation of a main heater (H), an adiabatic humidifying line (W.sub.L) showing the humidifying operation of an adiabatic humidifying device (W), a cooling line (C.sub.L) showing the cooling operation of a cooler (C) and an auxiliary heating line (RH.sub.L) showing the heating operation of the auxiliary heater (RH), and the end point temperature for each of the lines is set as the aimed exit temperature for each of the temperature/humidity adjusters (4, 4) and each of the temperature/humidity adjusters (4--4) is individually put to feedback control.
