1, the specific name of air conditioner eer is EnergyEfficiencyRatio, which means the refrigeration performance coefficient of air conditioner, which is often referred to as the energy efficiency ratio, representing the refrigeration capacity per unit efficiency of air conditioner. The higher the eer value of the air conditioner, the more energy absorbed by evaporation in the air conditioner and the less electric energy consumed by the compressor. In other words, we can get better cooling or heating effect by consuming less electricity.
2. The calculation formula of air-conditioning energy efficiency ratio is: air-conditioning energy efficiency ratio = refrigeration capacity ÷ refrigeration power. The cooling capacity mentioned above refers to the ability of air conditioner to adjust indoor temperature, and the cooling capacity refers to the electricity consumed by air conditioner during refrigeration. For example, there are two air conditioners with 5000 watts of cooling capacity at home, so the energy efficiency ratio =5000÷ 1500=3.3.
