Energy efficiency ratio
There are two kinds of energy efficiency ratio, cooling energy efficiency ratio EER and heating energy efficiency ratio COP. Under normal circumstances, as far as the air conditioning habits in most parts of China are concerned, air conditioning heating is only an auxiliary means of heating in winter, and its main function is cooling in summer, so the energy efficiency ratio of air conditioning we generally talk about usually refers to the cooling energy efficiency ratio EER.
Because the energy efficiency ratio of 1 class EER 1=3.4, and the energy efficiency ratio of class 5 EER 5 = 2.6, in order to achieve the same cooling capacity w, the air conditioner with 1 energy efficiency ratio must have the power of W/3.4, and the power consumption will be 24*W/3.4 degrees after running for 24 hours; An air conditioner with a five-level energy efficiency ratio will have a power of W/2.6. If it runs for 24 hours, it will consume 24*W/2.6 kWh. After running for 24 hours, the first stage saves more electricity than the fifth stage: (fifth stage power consumption-first stage power consumption) * 100%/ fifth stage power consumption = [(24 * w/2.6)-(24 * w/3.4)] *100%/(24)
Grade classification:
Grade 1 indicates that the product has reached the international advanced level and is the most energy-saving, that is, the lowest energy consumption;
Level 2 means saving electricity; Level 3 means that the product energy efficiency is the average level of China market;
Level 4 means that the product energy efficiency is lower than the market average;
Level 5 is the market access index, and products below this level are not allowed to be produced and sold.
