As we all know, the energy efficiency ratio of air conditioners is an important indicator for the purchase of air conditioners, but there are very few friends who really understand the energy efficiency ratio of air conditioners. So what is the energy efficiency ratio of air conditioners? How is the air conditioning energy efficiency ratio calculated? The following decoration house decoration network Xiaobian will answer for you one by one, I hope everyone can help after reading.
What is the energy efficiency ratio of air conditioners?
The energy efficiency ratio of air conditioning is the ratio of nominal cooling capacity (heat production) to operating power, ie EER and COP. The higher the energy efficiency ratio of the air conditioner, the more energy is saved, and the more money is saved at home, the country now manages to use environmentally friendly air conditioners. However, in terms of air-conditioning usage habits in most areas of China, air-conditioning heating is only an auxiliary means of heating in winter. Its main function is still summer cooling, so what we generally call air-conditioning energy efficiency usually refers to the cooling energy efficiency ratio EER. The relevant national standards are also used as the basis for delineating the energy efficiency rating.
What is the air conditioning energy efficiency ratio standard?
At present, the air conditioners sold in China have the color label "CHINA ENERGY LABEL", which is a color logo of blue and white background, which is divided into 5 levels of 1, 2, 3, 4, and 5:
Level 1 indicates that the product has reached the international advanced level, the most energy-saving, that is, the lowest energy consumption;
Level 2 indicates a comparison of power saving;
Level 3 indicates that the energy efficiency of the product is the average level of the Chinese market;
Level 4 indicates that the product's energy efficiency is below the market average;
Level 5 is a market access indicator, and products below this level are not allowed to be produced and sold.
Level 1 is the best and most energy efficient product. Energy efficiency ratios above 3.4 are primary products, 3.2-3.4 are secondary, 3.0-3.2 are tertiary, 2.8-3.0 are secondary, and 2.6-2.8 are secondary.
How is the air conditioning energy efficiency ratio calculated?
Air conditioning refrigeration energy efficiency EER = cooling capacity ÷ cooling power consumption
Air conditioning heating energy efficiency COP = heating capacity, heating power consumption
The above is what Xiaobian brought to you. What is the energy efficiency ratio of air conditioner? How is the air conditioning energy efficiency ratio calculated? I believe that everyone has a basic understanding of the energy efficiency ratio of air conditioners after reading this article.
