PURPOSE: A carbon dioxide supply controlling method and an apparatus thereof are provided to eliminate the supply of an incomplete combusted gas to an establishment when carbon dioxide is supplied to promote plant cultivation in an establishment such as a greenhouse or a vinyl house.CONSTITUTION: A carbon dioxide supply controlling method comprises the following steps of: (1) confirming a normal operational state of each sensor detecting the operation of the device and the environment in an establishment (2) confirming the selection for a driving mode for a manager from an automatic or manual combustion mode, heating mode, liquid gas feeding mode (3) performing the combustion mode supplying carbon dioxide and hot air generated during the fuel combustion to the establishment by controlling the operation of a burner (4) performing the heating mode supplying hot air generated during fuel combustion to the establishment by controlling the operation of the burner and (5) performing the liquid gas feeding mode supplying carbon dioxide to the establishment by controlling the operation of an electronic valve of a container, in which the liquid carbon dioxide is contained. In step (3), when the combustion mode is performed, the temperature inside a combustion chamber is measured while the fuel is combusted. When the temperature inside the combustion chamber is same or higher than a predetermined standard temperature, carbon dioxide is supplied to the establishment. When the temperature inside the combustion chamber is below the predetermined standard temperature, carbon dioxide is exhausted to the outside. In step (4), when the heating mode is performed, the entire carbon dioxide that is produced in the fuel combustion is exhausted to the outside and not to be supplied to the establishment.COPYRIGHT KIPO 2013[Reference numerals] (AA) Start (BB) End (S100) Confirming the normal operation of various sensors (S200) Selecting the driving mode of a driver (S300) Performing a comb
