What do you mean primary and tertiary energy consumption
The air conditioner whose energy efficiency ratio is in line with the first level becomes the first or third level energy efficiency air conditioner.1. The energy efficiency ratio actually reflects the cooling capacity of air conditioning products per kilowatt-hour of electricity consumed.This value reflects the energy saving situation of different air conditioning products.The lower the EER value, the more power the product consumes.Energy efficiency label, also known as energy efficiency label, is an information label affixed to energy-consuming products or their minimum packaging, indicating the performance indicators such as energy efficiency grade of the product.2. Unit energy consumption is a major indicator of energy consumption level, energy conservation and consumption reduction, and the ratio of total primary energy supply to GDP is an indicator of energy efficiency.This indicator shows the extent of energy use in a country’s economic activities, reflecting changes in economic structure and energy use efficiency.3. In fact, the primary and tertiary energy efficiency of air conditioners differ mainly in energy consumption. The difference between primary and tertiary energy efficiency is about 0.1 degree/hour.Taking a fixed frequency air conditioner with a cooling capacity of 2600w as an example, the EER of primary energy efficiency is 3.6 and that of tertiary energy efficiency is 3.2, which can be calculated according to the following formula.
