[0028] The first embodiment of the invention artificially feeds CO2 into the interior of the horticultural greenhouse by burning fuel in the burner 1 and feeding exhaust gas containing CO2 into the interior of the greenhouse. At this time, inside the burner, heat exchange is performed with heat generated at the time of combustion to generate warm water. This warm water is supplied to the heat-driven (heat-driven) refrigerator 3 . The heat-driven refrigerator 3 converts supplied warm water into energy to generate cold water. The generated cold water is then supplied to the heat-absorbing heat exchanger 6 to cool the exhaust gas containing CO 2 . Cooling the exhaust gases is preferably used to reduce the temperature to a temperature at which the gas can be supplied directly to the plants inside the greenhouse. However, it is not necessary to cool the gas to a temperature where it can be supplied directly. It is also possible to use additional coolers or the like to further co...

Abstract

The present invention discloses a carbon dioxide supply apparatus. The carbon dioxide supply apparatus is characterized by comprising a burner (1), a cooler (3) and a heat exchanger (6) for heat absorption. A fluid cooled by a cooling cycle of the cooler (3) flows through the heat exchanger (6) for heat absorption. The burner (1) comprises a combustion unit for combusting fuel; a first supply unit, wherein the first supply unit comprises an electric heater for heating the fuel to be supplied to the combustion unit and the first supply unit supplies the fuel heated by the electric heater to the combustion unit; and a second supply unit, wherein the second supply unit comprises a heat exchange unit for transferring heat of the combustion unit into heat for vaporization of the fuel, the second supply unit supplies the fuel heated by the heat exchange unit to the combustion unit, and the electric heater and the heat exchange unit are connected in parallel to the combustion unit.

Description

technical field [0001] The invention relates to a gas supply device, in particular to a carbon dioxide supply device. Background technique [0002] In a conventional horticultural greenhouse, a window connecting the inside and outside of the greenhouse is usually opened or closed to adjust the temperature and humidity in the greenhouse. At the same time, sunlight or artificial light is used for the light necessary for plants to perform photosynthesis. In order to realize an environment suitable for plants, regardless of the external air environment, a boiler for heating, a humidifier for adjusting humidity, and the like may be installed. In this horticultural greenhouse, air introduced from the outside is used to secure carbon dioxide (CO2) consumed during photosynthesis, CO2 produced by microorganisms living in soil etc. is used, CO2 gas produced by industry is used, and CO2 gas is used when burning fuel. Or CO2 produced after an oxidation reaction, or using other methods...
