Abstract

This research was conducted to establish efficient methods to overcome high temperature and low humidity with light selective shading agent and two-fluid fogging system in greenhouses in hot season. There were four experimental treatments; not treated (Non), fogging by two-fluid fogging system (Fog), spraying onto the greenhouse surface with shading coating agent (Coat), and using fogging and coating together (F&C). The amount of solar radiation entered into the greenhouses was higher in Non, and then Fog, Coat, and F&C in descending order. Fog was more efficient to lower the air temperature and also raise relative humidity than Coat treatment. The crop temperature was about $6^{\circ}C$ higher in Control than the other treatments. F&C revealed as the most efficient method to control the environment inside the greenhouse, but fogging system seemed to be more economic. In stand-alone greenhouses spraying coating agent may be the appropriate choice because of their structural limitations, mainly eave height.

본 실험은 광파장 선택형 차광제와 이류체 포그시스템을 이용하여 고온기 시설내 고온과 건조문제를 해소할 수 있는 적정 냉각법을 구명하기 위하여 수행되었다. 실험처리는 차광제와 이류체 포그시스템을 설치하지 않은 대조구(Non), 이류체 포그시스템만 설치하여 작동한 처리(Fog), 차광제만 도포한 처리(Coat), 외부에 차광제를 도포하고 내부에 이류체 포그시스템을 작동한 처리(F&C) 등이었다. 유입 일사량(열량)은 Non, Fog, Coat, F&C 순으로 많았다. 시설내 기온을 낮추는 방법으로는 이류체 포그시스템이 더 효과적이었다. 또한 이류체 포그시스템을 처리하면 상대습도도 적절히 조절할 수 있었다. 작물의 품온은 다른 처리구에 비해 대조구에서 약 $6^{\circ}C$ 이상 높았다. 연구결과, 고온기 시설내 광, 온도, 상대습도 환경조절에 가장 효과적인 방법은 이류체 포그시스템과 차광제 도포를 함께 하는 것이나, 효과 및 경제성을 함께 고려한다면 이류체 포그시스템을 활용하는 것이 가장 좋은 것으로 판단된다. 그러나 단동하우스의 경우에는 구조적 제약으로 이류체 포그시스템의 설치보다 광선 선택형 차광제를 도포하는 것이 더 좋은 방법으로 사료된다.
