본 연구에서는 실측을 통해 시설원예용 하우스의 난방방식별 온도분포 특성 및 하우스내 열환경을 상세하게 검토하였다. 하우스내 복사환경지표인 흑구온도는 주간의 경우 실내기준 온도보다 7
In this paper, the thermal characteristics in plastic greenhouses with heating systems of electric power, hot air, and non-heating are measured and analyzed by field tests. From these tests, we were able to estimate the heating efficiency and quantitatively evaluate the characteristics of indoor thermal distributions of the particular heating system in greenhouses. The heating system of electric power was ineffective to reduce the difference of thermal distribution in the vertical direction. The hot air heating system also does not properly reduce the serious temperature fluctuation by time. By removing the above problems, these data will be utilized effectively to design better thermal environment in greenhouses.
