HOT-AIR HEATING SYSTEM FOR PLASTIC GREENHOUSE FOR PROTECTED HORTICULTURE, AND CARBON DIOXIDE RECOVERY AND DISSIPATION SYSTEM AND METHOD FOR HOT-AIR HEATING SYSTEM FOR PLASTIC GREENHOUSE FOR PROTECTED HORTICULTURE
HOT-AIR HEATING SYSTEM FOR PLASTIC GREENHOUSE FOR PROTECTED HORTICULTURE, AND CARBON DIOXIDE RECOVERY AND DISSIPATION SYSTEM AND METHOD FOR HOT-AIR HEATING SYSTEM FOR PLASTIC GREENHOUSE FOR PROTECTED HORTICULTURE
PROBLEM TO BE SOLVED: To provide a hot-air heating system for controlling environment in a plastic greenhouse for protected horticulture to use a paraffin fuel, absolutely free from exhaustion of combustion gas from the greenhouse, and eliminating the need of the operation to open a roof window for temperature control in the daytime, thereby preventing the lowering of the effect of carbon dioxide stored in the greenhouse during the night.SOLUTION: The hot-air heating system includes an open-flame burning apparatus 40 placed in the plastic greenhouse 60 for protected horticulture and supplied with a paraffin fuel, a hot-air duct connected to the open-flame burning apparatus 40 and supplying the combustion gas into the plastic greenhouse 60, a temperature detecting means for detecting the air temperature in the plastic greenhouse 60, a blowing means for circulating and exhausting the air in the plastic greenhouse 60, and a controlling means for controlling the operation of the open-flame burning apparatus 40. The open-flame burning apparatus 40 includes a blower to send combustion gas into the hot-air duct and a hot-air generation means for elevating the temperature of the gas by the heat generated by the combustion of the paraffin fuel, and further provided with a carbon dioxide storage means for dissolving and storing the carbon dioxide in the plastic greenhouse 60.
