Controller of air conditioner

Abstract

Abstract PURPOSE:To eliminate the waste of energy of an air conditioner and to condition the air with effectiveness, by means of controlling the ability of a cooling and heating units by the difference of the outdoor temp. and the setting temp. in the room. CONSTITUTION:A signal Vo above the set value from an outdoor temp. detector 9, and a set value signal Vs from a temp. setter 13 are inputted into a positive and a negative input terminals respectively of a comparator 15, and the output Va which becomes to ON in Vo>Vs time, and becomes to OFF in Vo<Vs time, is inputted into an invertor 14 and an AND circuit 12A. An output Va' of the invertor 14 is inputted into an AND circuit 12B by becoming to the output with Va. The outputs C, W of a selector 10 of the operation state of the air conditioning and the outputs A1, A2 of an opening degree detector 11 of the mixed dampers of the cool wind and the worm wind, are inputted into AND circuits 12A, 12B, and the outputs of the AND circuits 12A, 12B control each of a compressor 5 and a warm water valve 6. The compressor 5 is actuated at the time when Va is ON, and C, A1 are ON, and the warm water valve 6 is opened at the time when Va is OFF, and Va' is ON and C, A2 are ON.
