(12) Rather than controlling the opening degree, a signal is output to control the opening degree to a predetermined opening degree (for example, the 5 steps described above). As described above, in the air conditioner control device of the present invention, the control valves (11), (t2) can be fully closed, and the control valves (11), (t2) can be fully closed.

合の立上り時間を短くすることができる。(G) Effects of the Invention As described above, in the present invention, when the control valve is controlled to be fully closed and the calculation means determines that the opening degree of the control valve is to be increased, the calculation means particularly controls the control valve. Since it outputs a signal to set the valve to a predetermined opening, the control valve is larger than conventional models that control the opening of the control valve according to the temperature difference between the room temperature and the set temperature. Controlled by the degree of opening, this increases the amount of heat exchanged indoors and shortens the time it takes to bring the indoor temperature closer to the set temperature. As described above, in the present invention, the control valve is controlled to be fully closed, and the rise time when the indoor temperature falls below the set temperature can be shortened.
