환기조건 및 관수에 따른 단동 플라스틱 하우스의 냉방효과와 열환경 분석
Analysis of Indoor Thermal Environment and Cooling Effects by Ventilation Condition, and Spray irrigation or Nonspray of Single Span Plastic Greenhouses

본 실험에 앞서, 하우스 4개동에 대한 대칭성 실험을 실시하였으나, 각 하우스간에는 최대1
In this study, we quantitatively compare the cooling effects of single span plastic greenhouses by opening or shutting of toot and side vents, and operation of fan or sprinkler. With those variables, we simultaneously made experiments at 4 greenhouses under equivalent conditions. By the experiments, the shutting of roof and side vents caused the high temperature difference of indoor and outdoor which the crops cannot be cultivated. However, the opening of the windows effectively reduced the indoor temperature and showed uniform temperature distribution in the greenhouses. The sprinkler abruptly reduced the indoor temperature, and showed excellent cooling effects. Finally, this paper provides the fundamental data for environmental control in greenhouses.
