An Experimental Study on the Indoor Thermal Environment of a Green House with Hot Air Heating System |
Abstract |
In a green house, there have been lots of indoor thermal problems due to thin thermal insulation, a large amount of irradiated solar heat, and low thermal capacity of plastic, etc. These problems have effect on the non-homogeneous air distribution in a green house. In the previous study, we have examined the In this paper, we examined the effect of the disposed interval of the air duct for supplying hot air to increase temperature in the green house. Three types of experiments were performed according to the interval of the hot alt duct, i.e., conditions of closely and unclosely crowded in that hot air duct intervals. Temperature, quantity of solar radiation, humidity, CO2 concentration were measured and analyzed to obtain some valuable data for designing better green houses. |
