Abstract:
To prevent adverse effects on crops by excess cooling by mist in a mist-type cooler for a cultivation greenhouse.
When the control of the mist-type cooling is started while driving a ventilation fan, the temperature is detected by an indoor temperature sensor 11, and when the detected temperature is higher than a set temperature, the mist type cooling is performed for a prescribed mist-type cooling time. When the mist-type cooling is finished, the mist-type cooling is stopped for a prescribed stopping time of the mist-type cooling.
