  • For this study grasp quantitative humidity variation with planting stratification to various green space of calculation method, observed humidity distribution in the green space. with this data, coverage condition and humidity distribution, planting calculation method and humidity, planting stratification calculation method and humidity, analyzed by revolution analysis. In this result, as well as coverage condition, planting stratification effect humidity variation. increasing planting ratio (area) and planting volume (capacity) effect higher humidity. especially, if we compared between planting stratification calculation method and higher humidity, effect by a revolution coefficient and a correlation coefficient, effect relatively planting volume (capacity) higher than stratification ratio (area). today, in the index of higher humidity, planting calculation propose application of capacity method.

  • The heat conduction and the water vapour diffusion flow through heat insulators between hygroscopical moist building materials were measured by means of the plate method. It was found that the heat transport increases with a moisture motion occuring in the temperature drop. On his basis of simplified assumptions, the increase in the thermal conductivity was calculated from the rate of diffusion flow per unit area, which generally resulted in values inferior to the measured values. The Increase in the heat transport due to water vapour diffusion measured at a large-scale wall specimen was inferior to the one measured by means of the plate method by using a comparable arrangement of layers. The overall heat transfer caused by moisture motion is not a characteristic value of the material, but a property of the whole wall structure

  • 1. 미스트를 장시간 분사시킬 경우 분사기간동안 온도강하는 분사량에 무관하게 일정하나 분사종료 후 온도상승은 분사량이 많으면 온도상승이 현저히 지연된다. 반면 증가된 습도는 장시간 유지되기 때문에 적정 분사량이 존재한다. 2. 시설하우스내 고온장애와 습도장애를 극복하고 보다 유리한 실내환경을 유지하기 위해서는 적정 미스트 분무량을 유지시켜야 하며 동시에 분무시간과 휴지시간을 충분히 고려해야만 한다.

  • In order to investigate the effects of foliage plants on the changes of indoor thermal- and hygro- environments, experiments were carried out in two rooms with similar physical factors. Changes of indoor environmental parameters according to the existence of plants, their arrangement methods, and the existence of wrapseal for protecting the loss of water from the pot soil were measured during certain periods in winter and summer season, using Pachira aquatica which is widely used as indoor plant and has higher photosynthetic and traspiration rate than other foliage plants. The data suggested that the existence of plants didn't affect directly on the indoor thermal environment, while relative humidity increased about 3~5%, regardless of season, by putting plants which had volume equivalent to 2.4% of room volume. In summer, there was no difference in increasing effect of relative humidity between parallel arrangement with window and spread arrangement in the room, but in winter the former arrangement was more effective than the later.

  • This study observed the temperature and humidity within the green zone to understand the effect that land coverage and the structure of forests have on the relief of micro-climate control. Based on this set of data, this study interpreted, through the regression analysis, the relevance of land coverage of the green zone with temperature and distribution of humidity, as well as the amount of green with the relief of microclimate control. The results of the study demonstrated that high temperature regions were formed in barren areas, and low temperature regions in forests or near the water. In particular, low temperature was found in areas covered with tall and small trees, the water surrounded by forests and areas enclosing small rivers. Furthermore, mechanisms causing low temperature were, among others, the ratio of land coverage (forest, grassland, water). In fact, the temperature reduction effect varied in accordance with the types and ratios of the land coverage. Humidity also showed a close correlation with the distribution of temperature high temperature areas had low humidity and low temperature areas had high humidity. Such a phenomenon.

  • 쾌적한 스포츠웨어는 기능성에 있어서 자연환경의 변화조건과 인체의 운동 및 활동에 맞추어 열절달 및 수분전달 등을 적절히 조절할 수 있어야 한다. 이에 본 연구에서는 일반환경조건 및 강우환경조건하에서의 형상기억 투습방수직물 소재의 스포츠웨어 착용에 따른 인체생리반응 및 쾌적감을 규명하기 위하여 스포츠웨어를 제작하여, 인공기후실에서 환경조건변화에 따른 온열생리학적 특성 및 주관적 감각을 측정, 그 특성을 비교, 고찰하였다. 평균피부온은 강우환경조건에서 온도가 낮게, 변동폭이 많게 나타났다. 변화경향을 운동부하를 기점으로 온도의 상승이 나타났고, 운동 2단계에 가장 높은 온도를 나타냈으며, 이후 감소하였다. 직장온은 일반환경조건에 비해 강우환경조건에서 온도의 미세한 상승을 보였다. 의복내 기후는 두 조건 모두에서 가슴부위보다 등부위의 온·습도의 변동폭이 크게 나타났고, 강우환경조건에서의 의복내 온도를 제외하고는 모두 등부위의 온·습도가 높게 나타났다. 최고 혈압은 운동의 강도에 따라 비례하여 상승하고, 최저 혈압에는 큰 영향없이 나타났으며, 변화경향은 의복내 온도의 경향과 역으로 나타났다. 평균혈압은 일반환경조건에서 6.9mmHg 높게 나타났다. 심박수는 일반환경조건에서 4.4beats/min 높게 나타났다. 강우환경조건의 주관적 감각의 평가에서, 신체에 직접 가해지는 빗물 등으로 인해 불쾌감이 증가하였고, 운동 후에는 일반환경조건과 달리 냉감이 증가하였으며, 습윤감은 최고치에 달하였다.

  • The showcase has insufficient temperature control, but it has excellent humidity control. The annual average temperature and relative humidity inside the showcase was $18.8^{\circ}C$ and 60.3%, respectively, and the showcase showed lower temperature and higher humidity than the exhibition room. The temperature inside the showcase appeared with high variation according to the seasons, while relative humidity was ranging from 59% to 61% regardless of the seasons. The showcase showed high temperature and humidity likewise the exhibition room in summer. In addition, lowering of temperature was elevated relative humidity according to the operation of air conditioner in summer. A moisture problem occurred because the temperature and humidity differences between the exhibition room and showcase were large according to the operation of air conditioner in winter. PI for temperature and relative humidity inside the showcase is 18.0%, and it means conservation environment for exhibition is unsuitable. In particular, continuous management of temperature and humidity inside the showcase is required because PI in the summer and winter is less than 1.0%.

  • 자갈축열 태양열 온실에 있어 여름철 냉방에너지의 효과적인 절감 방안을 모색하고자 축열 및 배기시스템의 작동방식을 다르게 하여 주ㆍ야간 축열과 방열시 자갈축열층의 온습도환경을 분석한 결과를 요약하면 다음과 같다. 1. 주간에 외기온이 28.5$^{\circ}C$-35.3$^{\circ}C$범위에서 변화할 때 자갈축열층내로 유입되는 공기의 온도는 30.5$^{\circ}C$-36.2$^{\circ}C$, 자갈축열층에서 온실내부로 유출되는 공기의 온도는 28.2$^{\circ}C$-30.1$^{\circ}C$, 축열층 내부온도는 27.4$^{\circ}C$-35.9$^{\circ}C$ 범위였다. 또한, 10시간 축열시 자갈축열층 내부온도는 측점에 따라 1.7$^{\circ}C$-7.$0^{\circ}C$의 온도상승이 있었으며 유입구에서 멀어질수록 축열층 온도는 낮게 나타났으며 온도상승 속도 또한 감소하는 경향으로 나타났다. 그리고, 야간에 축열시스템을 작동하지 않고 배기팬만을 작동하였을 경우, 외기온이 27.4$^{\circ}C$-34.4$^{\circ}C$범위일 때 자갈축열층 내부온도는 29.7$^{\circ}C$-34.9$^{\circ}C$(평균 31.4$^{\circ}C$)범위였으며 온실외부에 설치되어 있는 배기구와 배기팬의 영향으로 축열층 내부온도는 시간이 경과함에 따라 감소하는 경향으로 나타났으며 측점에 따라 2.2$^{\circ}C$-5.1$^{\circ}C$(평균 2.8$^{\circ}C$)의 온도하강 효과가 있는 것으로 나타났다. 2. 여름철 주간에 10시간 축열시 자갈축열층 내부습도는 측점에 따라 8.1%-26.3%의 감소현상이 있었다. 또한, 유입구에서 멀어질수록 축열층 습도는 높게 나타났으며 습도하강속도 또한 감소하는 경향으로 나타나 유입구에서 멀어질수록 외부습도의 영향을 적게 받는 것으로 분석되었다. 하지만, 야간에는 배기시스템의 영향으로 자갈축열층의 습도는 외기의 영향을 많이 받는 것으로 나타났다.
