하절기 온실의 활용실태 및 몇 가지 고온극복 방법별 열환경 분석
Actual Utilization and Thermal Environment of Greenhouses According to Several Cooling Methods during Summer Season
초록
온실의 경제적 고온극복 방안의 방향 설정을 위한 기초 자료를 얻기 위하여 비닐하우스 96농가, 유리온실 75농가를 대상으로 하절기 온실의 활용실태를 조사한 결과 유리온실 18.7%, 비닐하우스 24.0%, 전체 21.6%의 시설재배 농가가 휴경하고 있었으며, 나머지 경우도 매우 열악한 환경 하에서 재배가 이루어지고 있었고, 고온 극복을 위한 저비용 기술의 개발에 관한 요구가 매우 높았다. 냉방 및 보조냉방 처리별 온실의 열환경을 비교 측정한 결과 자연환기만으로는 74.8%, 지붕살수시 58.2%가 35
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
