초록

본실험에서는Ardisia속자생식물의온도및습도변화에따른온열환경을조사함으로써자생식물의이용에가능한기초자료를제공하고자실시하였다. 가로2m, 세로 1.3m, 높이 1.8m, 총부피가 4.68m3의밀폐된유리챔버내에온도조건변화에따른실내공간의온도및습도변화를측정한결과, Ardisia속식물에의한실내온도의변화는 24oC 이상의고온에서는식물이없는상태에비해감온효과가있었으며 3 종의식물간큰차이는보이지않았다. Ardisia속식물중에서백량금이온도변화에따른습도변화가가장민감하게일어나 13%의 습도변화를보였고, 57.3±3.1%로비교적높은습도를보였는데, 이에비해자금우는 8%, 산호수는 9%의습도변화를보였고자금우와산호수모두대부분의낮시간동안 50~55% 의실내적정습도범위를유지했다. 식물체의실내발열체로서의열성능평가결과, 실내온도를 28˚C에서26˚C로감온시에는식재에의한냉방효과가비식재공간에비해 7.5~13.6배높았고, 적정온도이상의고온에서는자금우에의한냉방효과가백량금과산호수에비해더좋았으며적정온도를유지하는데효과적이었다. 실내저온조건에서는비식재공간이식물을배치한경우보다높은열량을나타내식물이저온조건에서냉방효율을낮추므로적정온도를유지하는데효과적이었다. 이로서Ardisia 속식물은고온의실내에서주위의온도를저하시키고적정온도를유지시키는데효과적임을알수있었다.

This study investigated the changes of indoor thermal environment by Ardisia species planted in indoor space. Three Ardisia species (Ardisia japonica, Ardisia crenata and Ardisia pusilla) were used in this study and differences of temperature and relative humidity were ascertained in an empty chamber with and without plants. In high temperatures over 24oC, Ardisia species cooled down chamber more as compared to the control without plants, but there were no significant differences among Ardisia species. Ardisia crenata showed high relative humidity of 57.3±3.1% during most of the day time and 60.8±2.5% at low tempera­tures. However, Ardisia japonica and Ardisia pusilla showed 54.7±1.18% and 52.5±2.4%, respectively, on the average, and they maintained comfortable relative humidity during most of the day time. When the set­ting temperature was decreased from 28 to 26˚C, Ardisia species showed 7.5~13.6 times greater cooling effi­ciency as compared to the control without plants, and at low temperatures the chamber without plants showed higher themal energy than the chamber with plants. Ardisia species were effective on cooling down the temperature at high temperatures and they showed a tendency to maintain proper temperatures at low temperatures.
