Abstract

Internal environments of greenhouse are continuously influenced by the outside environmental conditions, which are different depending on the regions. This study aims to compare the environmental characteristics of Korean smart greenhouses built in different climate regions, Mongol, UAE (Abu Dhabi) and Australia (Queensland) during the hottest season. For both greenhouses in Mongol and Abu Dhabi, the calculated ventilation rate was increased according to the decrease of enthalpy difference between the internal and external during the daytime. In the semi-closed greenhouse of Abu Dhabi, the average temperature was lower about 7 to 10°C from 10 a.m. to 14 p.m. than that of external temperature, and the internal VPD (12 mbar) was 4.7-fold lower than that of external VPD (56 mbar), which is related to the operation of a fog system. For the greenhouse in queensland, the internal temperature was higher about 3.81°C than the external temperature at 11 a.m. with the higher internal enthalpy and VPD than those of external, and the ventilation rate was increased according to the increase in enthalpy difference in the internal and external. These results suggest that the the ventilation is associated with lowering enthalpy, while for lowering VPD, a fog system is essential equipment as the greenhouse in Abu Dhabi had a mcuh lower internal VPD. Also, it indicates that automated fogging, ventilation or heating systems on the base of enthalpy and VPD are necessary to effectively control appropriate climate conditions for plant growth.

온실 내부 환경은 지역에 따라 외부 환경의 영향을 지속적으로 받는다. 본 연구는 몽골, UAE(아부다비), 호주(퀸슬란드) 등 지역별로 구축된 한국형 스마트 온실의 환경 특성을 비교하고자 수행하였다. 몽골과 아부다비의 온실 모두 내외부 엔탈피 차이가 감소함에 따라 환기율이 증가하였다. 아부다비의 반밀폐형 온실에서는 10시부터 14시까지 평균 내부 기온이 외부 기온보다 약 7－10°C 낮았고 내부 VPD(12mbar)는 외부 VPD(56mbar)보다 4.6배 낮았는데 이 결과는 포그 시스템 운영과 관련이 있는 것으로 보인다. 퀸즐랜드 온실의 경우, 내부 온도가 외부 온도보다 11시 기준 약 3.81°C 높았고, 내부 엔탈피와 VPD가 외부 온도보다 높았으며, 내부와 외부의 엔탈피 차이가 증가함에 따라 환기율이 증가하였다. 이 결과로 엔탈피를 낮추는 것은 환기와, VPD를 낮추는 것은 포그 시스템 작동과 관련이 있는 것을 알 수 있다. 또한, 작물 생육에 적합한 환경 조건을 효과적으로 관리하기 위해 엔탈피와 VPD 기반의 포그, 환기 또는 난방 시스템이 필요하다는 것을 알 수 있다.
