온실의 태양에너지 이용을 위한 기초연구

In this study, heat storage energy in a green house which located in Jeju Island was measured. The green house has dimension with 25m(L) X 5.5m(W) X 4.0m(H). The heat in the green house is achived by the solar radiation during the daytime when the set temperature of the green house at 18℃. The temperature was measured with T-type thermocouple by data logger and was installed in the middle of the green house as evenly spaced in a vertical direction of the house. As results, the heat storage process is started when the outdoor temperature is over 15℃and solar radiation reached at 250W/m2. Also it is found that the system works with high efficiency at high daily temperature difference weather condition such as April and May.
