AI Technical Summary

Technical Problem

Existing indoor air conditioning systems contribute significantly to carbon dioxide emissions, and there is a need for carbon-neutral technology to minimize greenhouse gas emissions from buildings.

Method used

A carbon fixation indoor air conditioning system that integrates a user space, a plant factory section, and an air conditioning unit, with connecting pipes and a central control unit, allowing carbon dioxide from the user space to be fixed by plants, and recycled air to be purified and reintroduced, while using waste heat for energy savings.

Benefits of technology

Minimizes atmospheric carbon emissions by fixing carbon dioxide through plant growth, improves indoor air quality by reducing CO2 and increasing O2 concentrations, and optimizes air supply based on real-time environmental data for comfort, with energy savings from waste heat recovery.

Abstract

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.
