Efficient cooling in India

by Noe21


This program aims at phasing out synthetic super-greenhouse gases in India. Each mollecule of these "F-gases", widely used in refrigerators and air conditioners (ACs), is as climate damaging as 2'100 CO2 mollecules. Today new ACs running on 100% natural refrigerants and made in India must replace the use of F gas ACs. This discrete but vital program set in Mumbai and Delhi is aimed at developers to make them learn about and choose only natural refrigerant ACs for their future constructions.

Currently, 2 million household air conditioners (A/Cs) are sold annually in India. The annual sales growth rate has risen to 25%. All A/Cs sold in India today run on synthetic refrigerant gases: fluorinated gases, or Fgases, namely HCFCs or HFCs. If nothing is done to reduce the spread of HFCs, this gas could account for 20 to 40% of all carbon equivalent emissions by 2050.


In early 2012, a new generation of A/Cs running on natural gas HC-290 (hydrocarbon) was introduced. Their energy efficiency is 20% greater than those operating with HFC, thereby adding value to the final consumer and relieving the country of the additional energy demand in terms of additional coal, nuclear or hydro power plants. This advantage in terms of energy efficiency will be also critical to consumers for whom A/Cs weighs heaviest on their electricity bills.

Long-Term Impact

This project is due to reduce greenhouse gases emissions by both avoiding the use of super climate change gases and by reducing additional needs for coal and uranium power plants. The air conditioning sector is responsible for the major part of world F gas emissions as well as for the largest part of energy demand by households in hot and humid climate countries. This program aims at phasing out F gases in ACs and at increasing the energy efficiency in this high demand sector.
