The Air Conditioning industry’s nominal ratio for cooling (EER) and heating (COP) recent results have indicated a notable gap in predicted performances and actual achievement in the air conditioning industry.

An indication of how efficient an air conditioner is called ‘nominal efficiency’, when operated in normal conditions and operating in nominal conditions at full load (which isn’t always achieved). A more precise way is the ‘seasonal efficiency’ ratio (SEER) that has been specifically developed and gives a more accurate measure of the energy efficiency of ac systems.

Seasonal energy efficiency ratio (SEER) for air conditioning units provides a better true to life view of the energy efficiency. This includes, the performance of energy in various climate zones, either as part or full load efficiency, energy use in auxiliary as well as stand by modes and various load changes all year.

Consider asking your installer when buying your replacement or new air-con system about complying with the ErP. This will ensure they are energy-efficient and also will emit less CO2 emissions.
