| This study was performed to find an efficient method to overcome extremely high temperature in greenhouses during summer season. The actual utilization of greenhouses during hot summer season showed that about 21.6£¥ of the investigated greenhouse farms were in fallow state, and most of greenhouse farms were cultivated under the very inferior environment. Thermal environment of greenhouses according to the evaporative cooling method and several assistant cooling methods such as ventilation, shading screen, roof sprinkling were examined. As the each assistant cooling method was used, about 74.8£¥, 25.9£¥, and 58.2£¥ of temperatures measured at intervals of ten minutes between ten and seventeen o'clock were above 35$^{circ}C$. When shading screen and evaporative cooling system were operated, most greenhouse air temperatures were maintained below 35$^{circ}C$, and showed a drop of 3.8~4.2$^{circ}C$ as compared with naturally ventilated greenhouse. |
