Difference Between Air Conditioning And Refrigeration 2022

While rising up within the 1990s I used to listen to rather a lot about CFCs (or chlorofluorocarbons) and their involvement in depletion of ozone layer. There have been talks that every one the refrigerants that trigger environmental hurt shall be phased out. Difference Between Air Conditioning And Refrigeration

But because the years handed by, the considered checking if a fridge or air conditioner that’s being bought has environmentally pleasant refrigerant or not, vanished, because the presumption was that the CFCs have been phased out and we solely get environmentally pleasant refrigerants nowadays. But is that true? In this text, we are going to have a look at numerous refrigerants which might be utilized in air conditioners and fridges which might be out there in Indian market.

What is a refrigerant?

A refrigerant is a fluid that’s utilized in air conditioners and fridges, to take warmth from the contents of a fridge or the room (within the case of ACs) and throw the warmth out within the ambiance. A refrigerant undergoes part adjustments from a liquid to fuel (on absorbing warmth) and again to liquid (when a compressor compresses it). The selection of superb refrigerant is made primarily based on its favorable thermodynamic properties, non-corrosive nature, and security (non-toxic and non-flammable). Although many fluids can be utilized to behave as a refrigerant, however in 20th century, CFCs turned the most well-liked refrigerants.

Old and Modern refrigerants

The most typical refrigerant up to now was a CFC, mostly referred to as as Freon. Freon was a model title for a refrigerant “R-12” by DuPont.  In the 1990s and 2000s, the CFCs have been changed with HCFCs (hydrochlorofluorocarbon) and the commonest HCFC is “R-22”. 50-60% of Air Conditioners in India nonetheless (in 2016) use HCFCs. However, HCFCs are simply marginally higher than CFCs as they comprise chlorine, which is dangerous for the setting. As per Indian Government’s plan, HCFCs shall be phased out from India by the yr 2030.

To take away chlorine from the refrigerant, producers created one other set of refrigerants referred to as HFCs (or Hydro Fluro Carbons). Although additionally they have the potential for international warming, however nonetheless they’re higher than HCFCs as they don’t deplete the ozone layer. The most typical HFC utilized in air conditioners is R-410A. This refrigerant is healthier than R-22 by way of “Ozone Depletion” potential and vitality effectivity, but it surely nonetheless causes international warming. A number of extra HFCs which might be generally used are: R-32 in Air Conditioners and R-134A in fridges. About 20-30% of the air conditioners in India nonetheless (in 2016) use HFCs. R-32 is healthier than R-410A by way of international warming potential, however then it’s nonetheless an HFC. As per newest information, India plans to part out HFCs as properly in subsequent few years, and the timeline for it’s nonetheless into account.

The most environment-friendly refrigerants which might be out there in Indian market presently are “R-290” and “R-600A”.They even have high-energy effectivity however are extremely flammable as they’re hydrocarbons. But they’re the greenest refrigerants available in the market. Manufacturers, who use these refrigerants, declare that they’ve taken excellent care in utilizing these refrigerants and the home equipment are completely secure. In reality, most fridges within the Indian market are actually on R-600A and there are not any reported incidents of any accidents as a result of similar. So we will comfortably imagine that they’re secure.

Below is the information for Global Warming Potential of varied refrigerants (supply):

R-410A2088Zero
R-32675Zero
R-134A1430Zero
R-2903Zero
R-600A3Zero

Conclusion

If you might be somebody who cares about vitality effectivity and international warming, go for an Air Conditioner with R-290 or a Refrigerator with R-600A. The extra you go for it, the extra the producers will begin utilizing them of their home equipment. Hopefully, with stringent requirements and higher developments in expertise, we can see higher refrigerants in future.
