  • Temperature/humidity controller for use in an air conditioner and a recording medium storing temperature/humidity control programs used therefor
    Patent number: 6079483
    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.
