Performance Analysis of Alternate Purification System in Air Conditioning System

摘要

In the present work, the filtration system is combined with the air conditioning unit and hence utilizing the power of the air conditioning unit to drive the air through proposed purification system. The filtration unit is made up of multiple layers of filter with primary focus on keeping the air clean while at the same time keeping the cost down. The unit is made such that it is compatible with window air conditioners. The results show that the purifier lowered the concentration of PM2.5 by 40%, PM10 by 25%, SO_2 by 28% and NO_2 by 33%. This can be useful in polluted environments where AQI shoots past 200 and bringing it down to 120 or so can make a huge difference. When compared to the traditional HEPA filter which costs over Rs. 10,000 and filters the air by 99.97%, it might seem like a much poor choice. But AQI level of up to 100 is satisfactory and bringing down the level to 50 AQI is as good as bringing it down to 1. So, with some modifications, if one can increase the filtration rate up to 85%, AQI touching can be brought down 300 to less than 50. Thus, achieving similar purification levels as that of traditional air purifier for less than half the cost.
