What Specifications you must look for in an Air Conditioner


Following are some specifications you must look for while selecting and Air Conditioner

With raising prices, electricity bills are one of the most common concern in Pakistan and with the raising temperature intensity, Air Conditioners are becoming a necessity, day by day.

Refrigerant Gas

Today in Pakistan four most commonly used refrigerants in home appliances are R-22 R-134a R-400a and R-600a.

R-22

Some old Air conditioners still uses R-22 refrigerant. R-22 have harmful impact on Ozone layer and global warming as well. Also, the R22 gas have been banned by United States Environmental Protection Agency (US EPA). So, we don’t recommend appliances with gas R22.

R-410a and R310a

Today in Pakistan the most common refrigerant used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of Ozone Depletion Potential (ODP) and energy efficiency but have high global warming potential (GWP). Same is the case for R-134a which is also HFC based gas. Its also have zero ozone depletion potential and have less harmful impact on global warming as compared to R-410a.

R-600a

The greenest refrigerant available today in Pakistani market is R-600A. R-600a is HCFC based gas have zero ozone depletion rate and near zero global warming potential. They also have high-energy efficiency but are highly flammable as they are hydrocarbons. Still they are the most ecofriendly refrigerant available in the market. This refrigerant has started to grow its marketplace in Pakistan, it can now be found in refrigerators but is still rarely found in any Air Conditioner.

So, highly recommend appliances with gas R-600a.

The table gives the ozone depletion potential (ODP) and global warming potential (GWP) and Atmospheric life of commonly used refrigerant gases.

Seer Rating

When comparing central air conditioners, seasonal energy efficiency ratio, SEER rating is also important. Mostly it is ignored, but if you want to find it you can visit official websites to see it.
