ったのである。(Effects of the Invention) As explained above, in the ventilation g station operation control device according to the present invention, the indoor temperature detector (6) detects the indoor temperature.
and an outdoor temperature detector (7) that detects the outdoor temperature, and also detects the minimum indoor temperature that requires cooling, the maximum indoor temperature that requires heating, the minimum outdoor temperature that requires cooling, and the heating. It has a setting part (8) for setting a required maximum outdoor temperature, and when the indoor temperature detected by each of the detectors (8) and (7) is above the indoor minimum temperature, the outdoor temperature is above the above outdoor maximum temperature. , and when the indoor temperature is below the indoor minimum temperature, a temperature area that satisfies the condition that the outdoor temperature is above the outdoor minimum temperature is considered to be a cooling area, and when the indoor temperature is below the indoor maximum temperature, the outdoor temperature is below the outdoor minimum temperature and the indoor temperature is above the indoor maximum temperature, the temperature area that satisfies the condition that the outdoor temperature is below the outdoor maximum temperature is regarded as the heating area, and in the cooling area the indoor temperature is above the outdoor maximum temperature. When the indoor temperature is lower than the outdoor temperature in the heating area, and when the indoor temperature is higher than the outdoor temperature in the heating area, an instruction for heat exchange ventilation operation is output to the switching means (5), and when the indoor temperature is higher than the outdoor temperature in the cooling area. ,
In the heating region, when the indoor temperature is lower than the outdoor temperature, a controller (9) is provided that outputs an instruction for normal ventilation operation to the switching means (5), so that the air conditioner can self-determine whether to perform cooling or heating operation. above, the switching means (
5), it is possible to switch between the heat exchange ventilation operation and the normal ventilation operation, and therefore, this switching can be performed accurately, and comfort and energy saving can be improved.
