Gree air conditioner is the same, but the energy efficiency ratio is different. Is it better to be 3

The energy efficiency ratio is the ratio of the actual cooling capacity to the actual input power when the air conditioner is running under rated working conditions and specified conditions. This is a comprehensive indicator that reflects the amount of cooling converted per unit of input power into during the operation of the air conditioner. The greater the energy efficiency ratio of the air conditioner, the more electricity will be saved when the cooling capacity is equal.

Cooling energy efficiency ratio EER and heating energy efficiency ratio COP

There are two types of energy efficiency scores for air conditioners, namely the cooling energy efficiency ratio (EER) and the heating energy efficiency ratio (COP). Under normal circumstances, as far as the use habits of air conditioning in most regions of China are concerned, air conditioning heating is only an auxiliary means of heating in winter, and its main function is still summer cooling, so the so-called air conditioning energy efficiency ratio usually refers to the refrigeration energy efficiency ratio EER. [1]

Energy efficiency ratio code: EER air conditioner energy efficiency label.

1) The energy efficiency ratio of the air conditioner is the ratio of nominal cooling capacity (heating capacity) to operating power, that is, EER and COP.

2) EER is the refrigeration performance coefficient of the air conditioner, also known as the energy efficiency ratio, which indicates the cooling capacity per unit power of the air conditioner.

3) COP is the heating performance coefficient of the air conditioner, which indicates the heating production per unit power of the air conditioner.

4) The mathematical expression is: eer = cooling capacity refrigeration power consumption cop = heating heating power consumption.

5) The higher the EER and COP, the lower the energy consumption of the air conditioner and the higher the performance ratio.

High energy efficiency air conditioner = low energy consumption air conditioner national standard energy efficiency.

High energy consumption air conditioner = low energy efficiency air conditioner national standard energy efficiency.

High energy consumption air conditioner grade energy efficiency air conditioner) forced production in China in March 09.

The energy efficiency ratio is not or, it is good according to the power, and the energy efficiency ratio is good in the present tense!

When to buy an air conditioner? The original first-level energy-saving has been changed to the current second-level!

To be honest, there is not much difference, and even the difference cannot be made by using a pinch meter for air conditioner maintenance. Add more fluoride to the air conditioner or the shortcomings of fluorine will pass.

Gree air conditioning energy efficiency ratio 3 3 means air conditioning energy consumption ratio.

The energy efficiency ratio refers to the ratio of the cooling capacity to the effective input power of the air conditioner during refrigeration operation. The size of the energy efficiency ratio value reflects the cooling capacity of the air conditioner product for every 1000W of electric power consumed, and the energy efficiency ratio is the ratio of energy conversion efficiency.

The higher the energy efficiency ratio, the higher the energy conversion efficiency of the product, and the less electricity the air conditioner consumes per unit time. Generally, the energy efficiency ratio of 3 20 3 39 can be set as level 2 energy consumption.

Energy efficiency ratio. It means that the refrigeration performance coefficient of the air conditioner belongs to the secondary energy efficiency, and the cooling capacity of the air conditioner per unit power.

Energy efficiency ratio = QC divided by the nominal cooling capacity per unit time, unit kW, w represents the power consumed by the air conditioner per unit time, unit kW.

The magnitude of the energy efficiency ratio value reflects the energy savings of different air conditioner products. The higher the energy efficiency ratio value, the higher the energy conversion efficiency of the product, the less power consumption of the air conditioner Xunyu product per unit time.

The energy efficiency ratio of Gree air conditioner refers to the energy efficiency ratio (EER) of the air conditioner. The energy efficiency ratio is a measure of the energy efficiency of an air conditioner, which indicates how many units of cooling or heating capacity the air conditioner can provide for every 1 unit of electricity consumed. The higher the energy efficiency ratio, the more cooling or heating the air conditioner can provide under the same energy consumption, so the higher the energy efficiency ratio, the more energy saving advantages of the air conditioner.

In this case, the energy efficiency ratio of Gree air conditioner is that for every 1 unit of electricity consumed, the air conditioner is able to provide the cooling or heating capacity of the unit. This value is relatively high, indicating that the air conditioner has a better performance in terms of energy efficiency and is more energy-saving. Generally speaking, the higher the energy efficiency ratio, the lower the energy consumption and lower operating costs for users in long-term use.

It can be understood that the consumption of 1 unit of electricity can cool one unit.

The energy efficiency ratio of the air conditioner 3 3 means that the energy efficiency level of the air conditioner is level 2.

Classification of energy efficiency grades of air conditioners:

1. If the energy efficiency ratio of the air conditioner is more than 3 40, the energy efficiency level of the air conditioner is level 1.

2. The energy efficiency ratio of the air conditioner is between 3 20 3 39, and the energy efficiency level of the air conditioner is level 2.

3. If the energy efficiency ratio of the air conditioner is between 3 00 3 19, the energy efficiency level of the air conditioner is level 3.

4. The energy efficiency ratio of the air conditioner is between 2 80 2 99, and the energy efficiency level of the air conditioner is 4.

5. The energy efficiency ratio of the air conditioner is between 2 50 and 2 79, and the energy efficiency level of the air conditioner is 5.

The energy efficiency ratio of an air conditioner refers to the ratio of the nominal cooling capacity (heating production) of the air conditioner to the operating power, that is, the energy efficiency ratio and COP. The higher the energy efficiency ratio of an air conditioner, the more energy efficient it is, and the less money you save at home. The state is now managing to use environmentally friendly air conditioning.

Air conditioning energy efficiency refers to the ratio of user-defined cooling capacity to rated electricity consumption, and is usually a substitute for the energy efficiency ratio of household air conditioners. In addition, the concept of heating energy efficiency ratio (COP), which is the ratio of user-defined heat to rated power, is also included in air conditioning.

The energy efficiency ratio is how many kilowatts of cooling heat an air conditioner produces with one kilowatt of electrical energy. It is divided into refrigeration energy efficiency ratio EER and heating energy efficiency ratio COP. For example, the cooling capacity of an air conditioner is 4800W, the cooling power is 1860W, and the refrigeration energy efficiency ratio (EER) is:

4800／1860≈；The heating capacity is 5500W, the heating power is 1800W, and the heating energy efficiency ratio COP (auxiliary heating is not open) is: 5500 1800. Obviously, the greater the energy efficiency ratio, the more efficient the air conditioner will be, and the more energy-efficient the air conditioner will be.

Academically, the energy efficiency ratio is a relative value that varies with the specific conditions under which the air conditioner operates. Generally speaking, the higher the ambient temperature, the lower the energy efficiency ratio of the air conditioner. However, in terms of product standards, the energy efficiency ratio is an absolute value.

It is understood that at present, the average energy efficiency of air conditioners in China's market is relatively low. China's air conditioner output last year was 31.65 million units, accounting for more than 50% of the world's total output. It is estimated that more than 30 million of the approximately 40 million air conditioners sold worldwide last year were produced in China.

For every 100 air conditioners sold in the domestic market, only 3 units can achieve the energy efficiency ratio. The current energy efficiency standards for air conditioners in the United States were issued in 2000. According to this standard, the output power is between 2300W and 4100W, that is, the air conditioner is small by 1 HP to HP, and the energy efficiency ratio is qualified product; The energy efficiency ratio reaches the Energy Star standard; The energy efficiency ratio is lower than that, and it is not allowed to be sold in the U.S. market.

According to the European energy efficiency standard, the energy efficiency level of air conditioning is divided into 7 levels: A, B, C, D, E, F, and G. Among them, grade A is the highest, and the energy efficiency ratio is above; Grade D is in the middle, between; Class E or less is classified as a low-efficiency air conditioner. At present, the vast majority of air conditioners in China are at the European E-level level.

In Japan, the energy efficiency ratio of air conditioners is generally around the same level.
