Abstract
This study aimed to collect the carbon dioxide generated as a by-product from petrochemicals and liquor factories and use it in a crop breeding greenhouse. This was applied mainly to the storage of dry ice and the supply of carbon dioxide to achieve this target. Dry ice has a strong cooling effect because CO2 becomes a solid or gas at temperatures and pressures below the triple point, and the solid sublimes at -78.5℃ and atmospheric pressure. The consumption of dry ice according to temperature was 0.983kg/day, 2.358kg/day, 5.102kg/day, and 7.035kg/day when the temperature was 5℃, 10℃, 15℃, and 20℃, respectively, which corresponded to 1,102ppm, 1,481ppm, 1,677ppm, and 1,855ppm. Dry ice consumption in the test greenhouse decreased by approximately 0.9kg/h, and the CO2 concentration in the greenhouse at 9 a.m., before supplying dry ice increased to 517ppm, 1,519ppm at 10 a.m., 1,651ppm at 11 a.m., and 1,651ppm at 12 p.m., before maintaining this level of activity. Overall, this study attempted to contribute to increasing farm income by deriving the supply conditions through an expansion of the supply of carbon dioxide gas for crops.
