Indoor Air Purification by Plants Experiment and Its Arithmetic Mean and Regression Analysis

Abstract

Plants can purify indoor air quality; in particular, plant transpiration can facilitate indoor air movement, purify air by removing pollutants effectively, and provide clean indoor air. In this study. The first and second stages mainly focused on selecting plants with superior performance in the indoor spaces. In the final stage, the effects of different arrangements of grow lights and air conditioners were investigated. The arithmetic mean and regression analysis results demonstrated that the plants illuminated with grow lights had superior performance. Plants that performed photosynthesis and transpiration simultaneously could lower the average temperature, increase indoor humidity (to make up for the lack of cold room humidity), and lower CO2 concentration. Our results demonstrated that placing plants together at a location across the air conditioner and under grow light illumination afforded the most effective indoor air purification and CO2 removal.
