The Korean facility horticulture industry is on the rise. However, climate change and warming are making it more difficult to produce crops in the summer. Therefore, it is necessary to input a technology capable of reducing the cooling load. This study is a technology development that combines an air airflow fan and a fog spray device. This technology can effectively lower greenhouse temperatures. In addition, farmers can reduce installation costs. There are 126 farms using airflow fans in 426 farms in the facility horticultural greenhouse, accounting for 30%. A typical fan size is 30 cm. Up to 10 fog nozzles can be attached here. Dry-bulb, Wet-bulb, Controller, Inverter type pump, Water reservoir, and Fognozzles are required to operate the airflow fan and fog combined system. The control system allows the step and range to be set and the operation time to be input. As a result of wind velocity, it was confirmed that the left point was measured low and the distance decreased. Considering the wind distance, arrangement, orientation, and installation intervals should be adjusted so as not to affect the crop. The particle size increases as the distance increases. The attachment of less than 10 fog nozzles and the use of high pressure nozzles should be considered. It is necessary to find out the actual efficiency of the airflow fan and fog combined system through further research.
