Inside Environment Variation of Solar-Heated Greenhouse with Rock Bed Storage in Summer Season

Objects of this study were to find the cooling effect of solar-heated greenhouse with rock bed storage in summer season and to suggest operation method of cooling energy saving in summer cropping greenhouse. Experiments were performed to analyze inside environment variation of solar-heated greenhouse. When we took account of different shading and ground conditions of greenhouse, we could conclude that inside average daytime temperature of the solar-heated greenhouse was 2.0∼2.4$^{\circ}C$ lower than the general greenhouse in summer season.
