The adaptability of an evaporative cooling system to hot summer climate in greenhouses was comprehensively judged by fuzzy theory, based on the 20 years(1975~1994) weather data of nine representative regions in Korea. As uses the evaporative cooling system for greenhouses during summer in Korea, the inside air temperature of most regions except the southwest coastal areas, the south coastal areas, and Cheju island can be basically controlled below 32.5$^{\circ}C$, and ventilating air can be cooled 5$^{\circ}C$ and more. The analyzed results in this paper are on the basis of good ventilation system. When the evaporative cooling system is applied, the ventilation system which has good air flow organization is needed. Although the summer climate in Korea is high temperature and humidity, evaporative cooling systems are suitable for farm buildings in most regions. This facts better meet the needs of cooling for greenhouse in summer and provides a scientific basis for spreading the evaporative cooling system It is proposed that the further research is needed about the application of evaporative cooling system to greenhouses.

증발냉각시스템의 원리는 물이 수증기로 상태변화할 때 필요한 기화열을 주변으로부터 공급받으면서 공기의 온도가 감소하는 것이다. 이것은 덥고 건조한 지역에서는 매우 효과적이지만 상대습도가 높은 지역에서는 냉방효과가 낮다. 따라서 국내의 모든지역에 증발냉각시스템의 적용이 적합한지는 의문이다. (중략)
