Top 5 most Eco-friendly Air conditioner system in India

Eco friendly AC

[ Updated on ]

AC has been long accused of being one of the big reason for greenhouse gas emission which hampers environment.  A wise choice while buying an AC by choosing Eco-friendly AC, helps you in contributing towards a greener Earth of tomorrow.

What makes an AC Eco-friendly? What differentiate a normal AC with Eco-friendly AC?

Your AC unit uses refrigerant for cooling purpose. Refrigerants are nothing but chemical compound which exists either in fluid or gaseous state and have heat absorption capability.  It gives you cooled air through inside unit by heat exchange.

An AC is Eco-friendly for not depends on the refrigerant that is being used is Eco-friendly or not.  

Refrigerants are assessed in the term of GWP and ODP which is Global warming potential and Ozone Depletion potential respectively.

What is GWP and ODP?

Refrigerants used in cooling system today are often thousands of times more polluting than carbon dioxide (CO2). The GWP of a gas refers to the total potential contribution to global warming resulting from the emission of one unit of that gas relative to one unit of the reference gas, CO2, which is assigned a value of 1. 

An AC which is using refrigerant for cooling with high-GWP impacts global warming and climate change very badly.

ODP of a refrigerant is the ratio of the impact on ozone layer of that chemical used in refrigerant compared with the impact of a similar mass of CFC-11 (R11), which is assigned ODP value of 1.

CFCs and HCFCs have ODPs ranging from 0.01 to 1.0. The halogens(F,CL,Br,I) have ODPs ranging up to 10. Carbon tetra-chloride has an ODP of 1.2 and methyl chloroform’s ODP is 0.11. HFCs have zero ODP because they do not contain chlorine.

Being informative about refrigerant helps you in choosing Eco-friendly AC system for you home. Beyond this there are many brands with many other features that could make choice of best AC a bit confusing. We have analysed various products and feedback of customer and have simplified the list of green Air conditioner.
