This study is to perform the effect of urbanization in urban and suburban districts, and to identify regional characters of climate according to the analysis of slope at rise, and descent of temperature and globe temperature, correlation between seasonal temperature analysis, and calculation of degree hour. According to this study, the result is summarized as follows. (1) The average temperature, rated from high to low, consists of residential area, Daegu weather station, intracity, green belt, water-front green belt, and suburban. (2) At the rise and descent of temperature, the result of the slope change of in each point may be one of the useful indexes to be able to perform the regional unique thermal characteristic, including the seasonal urbanization. (3) Although there is a difference between the surface of the earth and ambient environment. The result of the correlation of temperature between summer and winter is that temperature slope in urban districts was higher than in suburban districts, and the difference of slope was unvaried among the four observations in the same city region. (4) To show objectively, regional thermal characteristics in urban and suburban districts, the exponentiation of winter degree hour and summer degree hours were checked. The result of the exponentiation is that the more artificial a region, the lower index.

The objective of this study is to analyze the characteristic of thermal environment in the summer season by conducting the field observation of temperature, relative humidity, and globe temperature in some parts of the city. Observation point was divided to a densely populated area, a residential area, a green area, a waterfront green area and a suburban district by the distribution ratio of green area. In this study, the correlation between maximum temperature and globe temperature, study on index for intensity of the tropical night and the temperature distribution characteristic of measurement points by the distribution ratio of green area were analyzed. The results of this study are as follows. (1) The difference between temperature and globe temperature by the distribution ratio of green area is confirmed. The difference of nighttime is more clearly that of daytime. (2) The average temperature and globe temperature of the densely populated area($29.2^{\circ}C$, $33.7^{\circ}C$) are higher than that of the waterfront green area($27.9^{\circ}C$, $32.0^{\circ}C$) by $1.3^{\circ}C$ and $1.7^{\circ}C$, respectively. (3) The number of tropical nights has different days of tropical nights by the distribution ratio of green area of 17days for the Daegu weather station, 14days for adensely populated area, 14days for a residential area, 6days for a green area, 2days for a waterfront green area, and 2days for a suburban district. (4) The results of the slope of trend line for the effects of the temperature on globe temperature change and the intercept for the size of the impact of radiant energy gained around by the analysis of the correlation between the maximum temperature and globe temperature can be utilized objective evaluation index of the each point's artificial effects.

본 연구에서는 큰 느타리버섯 재배사의 에너지 이용효율과 소요에너지 산정에 대한 기초 자료를 얻기 위하여 기존에 제시한 재배사모형(영구형 단동 및 연동과 반영구형 단동)들을 대상으로 열수지 시뮬레이션을 실시하였다. 또한 재배사의 단열재 및 피복재의 열전달 저항치를 산정한 후, 재배사의 냉$\cdot$난방 부하량을 추정하였다. 진주지방의 경우, 큰 느타리버섯 재배사의 냉$\cdot$난방 D-H 증감현상은 실내 설정온도의 변화에 따라 거의 직선적인 변화를 보였으며, 변화의 정도는 냉방 D-U가 난방 D-H에 비해 훨씬 예민하다는 것을 알 수 있었다. 따라서 설정온도는 물론 실내 유지온도의 제어 양상에 따라 소요 에너지의 변화를 예측할 수 있을 뿐만 아니라, 앞으로 개발될 버섯 재배사의 환경모형 시뮬레이션 검정과 에너지 소요량 추정에도 산정 된 D-H가 유익하게 활용될 수 있을 것으로 판단되었다. 그리고 동일한 재배공간 확보를 전제로 할 경우, 다중 피복의 반영구형 재배사에 비해 다양한 두께 및 재질로 생산되고 있는 영구형 재배사가 단열성능 면에서 현저히 유리하였다 단동 대비 연동구조의 에너지 효율, 단열 정도에 따른 에너지 소요량의 변화를 쉽게 가늠할 수 있을 뿐만 아니라 주어진 지역과 주요 표면의 단열 정도와 표면상태 등에 따라 계절별 또는 재배 주기별 소요 에너지를 예측함으로서 재배사의 구조 및 환경적 최적화를 꾀할 수 있을 것으로 판단되었다.
