The present invention relates to a hydroponic nutrient solution supply system and, more particularly, to a hydroponic nutrient solution supply system comprising: a plant cultivation unit in which a plant is cultivated hydroponically; an image information collection unit that collects, by using a camera device, image information of the plant being cultivated in the plant cultivation unit; a nutrient solution supply unit connected to a plurality of nutrient solution concentrate tanks to supply nutrient solutions of various compositions to the plant cultivation unit; and a nutrient solution control unit that determines the growth stage and growth rate of the plant being cultivated, on the basis of the image information of the plant collected by the image information collection unit, and then controls, in response to the determined growth stage and growth rate, the composition and amount of the nutrient solution supplied from the nutrient solution supply unit to the plant cultivation unit.
The present invention relates to a carbon fixation indoor air conditioning system. More specifically, the system comprises: a user space unit formed in a divided space of a building as a space in which humans or animals live, the user space unit having a first air inflow hole through which external air is introduced into the space, and having a first air outlet hole through which internal air is discharged to the outside of the space; a plant factory unit formed in another divided space of the building such that plants are grown in the space, the plant factory unit having a second air inflow hole through which external air is introduced into the space, and having a second air outlet hole through which internal air is discharged to the outside of the space; an air conditioning unit provided in an area of a building, the air conditioning unit having a third air inlet hole through which external air is introduced therein, and having a third air outlet hole through which internal air is discharged to the outside, the air conditioning unit being configured to change the temperature of air introduced through the third air inlet hole in a heat exchange type and then discharge the air through the third air outlet hole; a first connection pipe for connecting the first air discharge hole and the second air inlet hole such that the air discharged from the user space unit flows into the plant factory unit; a second connection pipe for connecting the second air discharge hole and the third air inflow hole such that the air discharged from the plant factory unit flows into the air conditioning unit; a third connection pipe for connecting the third air discharge hole and the first air inflow hole such that the air discharged from the air conditioning unit flows into the user space unit; and a central control unit for controlling the operation of the air conditioning unit.
