What is the relationship between the energy efficiency ratio and energy efficiency grade of an air c

The energy efficiency ratio refers to the ratio of the rated cooling capacity to the rated power (electricity consumption).

Energy efficiency grade is a grading method that represents the difference in energy efficiency of air conditioning products, China's energy efficiency is divided into 5 grades, the background color of the energy efficiency mark is blue, and there is information such as "producer name" and "specification model" at the top; The most eye-catching is the middle part of the logo, which has a grade mark from 1 to 5, from green to red, and a message on the left to indicate from "low energy consumption" to "high energy consumption", and the upper right corner clearly indicates the energy efficiency level of the product of this specification and model. The lower part of the logo provides specific data on "Energy Efficiency Ratio", "Input Power" and "Cooling Capacity".

Energy efficiency grade is a grading method that represents the difference in energy efficiency of air conditioning products, and the energy efficiency score of air conditioning is divided into five levels in accordance with the relevant provisions of national standards. The energy efficiency mark is to, and the energy consumption level is level 5 energy consumption; The energy efficiency mark is to, and the energy consumption level is level 4 energy consumption; The energy efficiency mark is to, and the energy consumption level is level 3 energy consumption; The energy efficiency mark is to, and the energy consumption level is level 2 energy consumption; The energy efficiency mark is above and above, and the energy consumption level is level 1 energy consumption. According to the regulations, if the product is below the minimum market access level 5 energy efficiency, it is not allowed to be sold on the market.

Level 1 is the most energy-efficient, Level 5 is the least energy efficient, and products above Level 5 are not allowed to be marketed. Air conditioning companies are required to affix energy efficiency labels to their products to inform consumers of their energy efficiency levels. Consumers can clearly know which air conditioner is energy-efficient directly through the energy efficiency rating sticker.

Taking a 1 5 hp air conditioner as a reference, the hourly power consumption of the first-class product shall not exceed 1 kWh, and the hourly power consumption of the fifth-grade product shall not exceed 1 35 kWh.

The number of air conditioner horsepower originally refers to the input power, including the press, fan motor and electronic control part. Due to the differences in the specific system and electronic control design of different brands, the cooling capacity of their output is also different, so their cooling capacity is calculated by output power. Generally speaking, the cooling capacity of 1 horse is roughly 2000 kcal, which should be multiplied in SI units, so the cooling capacity of one horse is 2000.

The W (watts) here represents the cooling capacity. The horsepower should be 2000, and so on, which can roughly judge the number of horsepower and cooling capacity of the air conditioner. Under normal circumstances, the cooling capacity of 2200 2600W is called one horse, 3200 3600W is a horse, and 4500 5500W is 2 horses.

The number of horsepower you provide is the cooling capacity (1 horsepower is about 2350, that is, 1,5p is about 3500), the ratio of cooling capacity to cooling power (heating and heating power) refers to the energy efficiency ratio, and the energy efficiency level refers to the degree of electricity saving, which is related to the energy efficiency ratio! The higher the energy efficiency ratio, the higher the energy efficiency rating!

Let's see what others have to say.

The energy efficiency ratio of an air conditioner is the ratio of nominal cooling capacity (heating capacity) to operating power.

The energy efficiency ratio refers to the ratio of the cooling capacity of the air conditioner to the input power of the air conditioner, reflecting the energy saving level of the air conditioner. According to the ratio of cooling (heating) power to input power, that is, the size of the energy efficiency ratio, with each increase as the identification standard, the grade difference is delineated, and the fixed-speed air conditioner is divided into 5 grades.

Level 1, Level 2, Level 3, Level 4, Level 5. Generally, air conditioners that are lower than the energy efficiency ratio are not eligible to enter the market. The higher the energy efficiency ratio, the more energy efficient it is. In other words: Level 1 is the most energy-efficient.

First of all, it can reflect the heating or cooling effect of this air conditioner, and it can also reflect his power consumption.

We try to choose some air conditioners with low refrigeration, because such air conditioners have a relatively low damage to our body, and they can actually play the role we want.

The energy efficiency level of an air conditioner represents the level of energy consumption of the air conditioner. When buying, you should choose some air conditioners with more grades, so that you can have a better right to choose the grade.

This represents the power and the use and consumption of electricity, and the best choice of the first level when buying, which means that the power consumed by Hu Liang with this product is very small and special power saving.

It represents the energy efficiency ratio of refrigeration, which is energy consumption divided by efficiency. At the time of purchase, under the same power, choose the one with high efficiency.

It represents a graded approach to air conditioning from high to low, and you should choose the 5 levels when buying, because this is the most energy-efficient.

The energy efficiency ratio and energy efficiency rating of an air conditioner are two different concepts, and the differences between them are as follows:

1. Quiet lead energy efficiency ratio.

The energy efficiency ratio of an air conditioner refers to the ratio between the electrical energy consumed by the air conditioner in the process of cooling or heating and the cooling or heating process. Generally speaking, the higher the energy efficiency ratio, the less electricity the air conditioner consumes when cooling or heating, and the better the performance.

2. Energy efficiency level.

The energy efficiency rating of air conditioners is based on national standards to evaluate the energy efficiency ratio of air conditioners. At present, the energy efficiency level of air conditioning in China is divided into 1-5 levels, of which level 1 is the lowest level and level 5 is the highest level. The higher the energy efficiency level, the higher the energy efficiency ratio of the air conditioner and the better the performance.

Therefore, the energy efficiency ratio and energy efficiency grade of air conditioners are both important indicators to measure the energy efficiency performance of air conditioners, but the relationship between them is not a simple linear relationship. Even if two air conditioners have the same energy efficiency ratio, their energy efficiency ratings may be different, depending on other factors such as the design of the unit, manufacturing process, service life, etc. Because of this, when buying air conditioners, in addition to paying attention to energy efficiency levels, it is also necessary to compare the energy efficiency ratios of different brands and models, and choose more energy-saving and environmentally friendly products.

1. Refers to different drawbacks.

1. Energy efficiency ratio: It is the ratio of energy conversion efficiency. The ratio of the rated cooling capacity to the rated power (power consumption).

2. Energy efficiency grade: a grading method that indicates the difference in energy efficiency of air conditioning products.

Second, the role is different.

1. Energy efficiency ratio: The value of energy efficiency ratio reflects the energy saving of different air conditioner products. The higher the energy efficiency ratio value, the higher the energy conversion efficiency of the leased product, and the lower the power consumption of the air conditioner product per unit time.

2. Energy efficiency level: Level 1 means that the power saving of the product has reached the international advanced level and the energy consumption is the lowest; Level 2 indicates that the product is relatively power-saving; Level 3 means that the energy efficiency of the product is the average level of the Chinese market; Level 4 indicates that the energy efficiency of the product is below the market average; Level 5 is a product market access index, and products below the requirements of this level are not allowed to be produced and sold.

Third, the characteristics are different.

1. Energy efficiency ratio: EER is the refrigeration performance coefficient of the air conditioner, called the refrigeration energy efficiency ratio, which represents the refrigeration under the unit power of the air conditioner, and the spine calculation formula QC refers to the nominal cooling capacity per unit time, and the unit kW, W represents the power consumed by the air conditioner per unit time, and the unit kW

2. Energy efficiency rating: Energy efficiency standards and energy efficiency labels have proven to be the most cost-effective way to reduce energy consumption, while bringing significant environmental benefits and providing positive returns for consumers.

The difference between the energy efficiency ratio and energy efficiency rating of <> air conditioner is as follows:

The definition is different: the energy efficiency ratio refers to the ratio of energy conversion efficiency, which is the cooling performance coefficient of the air conditioner, which is the cooling capacity divided by the input power. Energy efficiency grade is a grading method that indicates the energy efficiency of household appliances, and the energy efficiency is divided into five levels according to the relevant national standards.

The energy efficiency ratio is the ratio of the air conditioner in the refrigeration process, the cooling capacity to the refrigeration power. According to the national implementation rules, the energy efficiency grade standard of air conditioners will be implemented on July 1, 2010.

The characteristics are different: the energy efficiency ratio refers to the ratio between the loss of cooling capacity and the effective use of heat, the higher the value, the better the energy efficiency level of the air conditioner. The determination of energy efficiency level has a certain authority, and it is also related to the country's energy-saving requirements.

In general, the energy efficiency ratio of air conditioners indicates the ratio of energy conversion efficiency of air conditioners during the cooling process, while the energy efficiency rating indicates the grade of household appliances in terms of energy utilization.

The energy efficiency level of air conditioning refers to the energy efficiency grade standard of air conditioning, and is used to evaluate the energy efficiency of air conditioning, which is generally divided into energy efficiency level 1 to energy efficiency level 5. The energy efficiency ratio of air conditioning is the ratio of cooling or heating efficiency to energy consumption of air conditioners, which is generally used to evaluate the energy saving degree of a single air conditioner, and its higher value indicates the higher the cooling or heating efficiency per unit of energy consumption. Therefore, the energy efficiency ratio of air conditioning is to evaluate the energy saving of a single air conditioner, and the energy efficiency level of air conditioning is to evaluate the energy efficiency of products in the entire air conditioning market.

Level 1 is the most energy-efficient; 2. The energy-saving efficiency of level 4 is gradually reduced; Level 5 is the lowest energy saving level, which is the threshold level for products to enter the market.

For air conditioners, the same air conditioners, compared with level 1 air conditioners and level 5 air conditioners, Yingqi saves 200-300 yuan in electricity costs every year, and the purchase of level 1 air conditioners is only about 800 yuan more than the purchase of level 5 air conditioners, which means that at least 2,000 yuan can be saved during the 12-year use of air conditioners.

Since the energy efficiency ratio of level 1 is eer1=, while the energy efficiency ratio of level 5 is eer5=; In order to achieve the same cooling capacity W, the air conditioner with the 1st level of back-to-hu energy efficiency ratio must have W of power, and it will consume 24*W kWh of electricity after 24 hours of operation.

The air conditioner with a level 5 energy efficiency ratio must have W of power, and it will consume 24*W kWh of electricity when it runs for 24 hours; At this time, it runs for 24 hours, and the first level is more power-saving than the fifth level: (five-level electricity consumption first-level electricity consumption) 100% fifth-level electricity consumption [(24*W, ieThe energy efficiency level of the air conditioner is level 1 and energy saving compared to level 5.

What does the energy efficiency rating of an air conditioner mean? What is the impact of energy efficiency ratings on the use of air conditioners? What does the energy efficiency rating of an air conditioner mean?

The efficiency rating of an air conditioner refers to the energy efficiency ratio of an air conditioner, that is, the ratio of the rated cooling capacity to the rated power consumption. In layman's terms, how much air conditioning is produced by consuming the same amount of power is an important parameter to measure the performance of air conditioners. The state has promulgated the energy efficiency ratio standard for air conditioning products, and the energy efficiency ratio of ordinary fixed-speed air conditioners is level 5 (the national standard for energy efficiency ratio of inverter air conditioners is being formulated).

<> any project has its advantages and disadvantages, and as a household appliance, energy efficiency is an important indicator to measure household appliances, the lower the energy consumption, the better the energy saving effect, and as a very important household appliance air conditioner in the home, what does the energy efficiency level of air conditioning mean? We rarely think about these issues in our daily lives, and this is what professionals need to know. Therefore, this article makes a specific statement on these two issues.

The energy efficiency level of air conditioning, also known as air conditioning energy efficiency comparison, is the name of what we call air conditioning energy efficiency comparison (survey), which is the ratio of rated power to rated cooling capacity.

The change in temperature type also includes the concept of energy efficiency comparison (COP) of heating household air conditioning, which refers to the ratio of heat to rated power, but for the use habits of air conditioning in most parts of our country, air conditioning heating is only an auxiliary means of heating in winter, and its main function is still summer refrigeration, so we usually call it air conditioning energy efficiency, usually refers to the role that refrigeration can play, and the relevant national standards surveyed are also based on defining the energy efficiency level, informally, air conditioning energy efficiency refers to the consumption of the same amount of cold The amount of electricity generated by heat, the higher the energy efficiency of the air conditioner, the less electricity it consumes; Therefore, air conditioning energy efficiency is an important parameter to measure the performance of air conditioners.

At present, air conditioners sold in China will be marked with a color label of "China Energy Label", which is a blue and white background color label, divided into, grade 1 indicates that the product has reached the international advanced level, with the most energy saving, that is, the lowest energy consumption; Level 2 indicates that the product will be more energy efficient; A level of 3 indicates that the energy efficiency of the product is the average for the Chinese market.

It means that the energy consumption of the air conditioner will be closed, and the energy efficiency of the air conditioner will be planned according to the grade index of different debate wheels. It can ensure the refrigeration effect of the air conditioner, and also ensure that the car stove of the air conditioner is reused, which is conducive to improving the use level of air conditioning, can ensure the identification of energy efficiency, can also promote the development of technology, and can also ensure the service life of the air conditioner.

The energy efficiency level of an air conditioner generally refers to the electricity consumption of the air conditioner; The higher the energy efficiency level, the lower the power consumption of the air conditioner, and the more energy-saving we will be when we use it in daily use.

The energy efficiency level of an air conditioner refers to the amount of cold air that can be generated at the same time and the amount of electricity that needs to be consumed. The higher the energy efficiency level, the longer the service life of the air conditioner, and the higher the utilization rate of the air conditioner.

The lower the number of energy efficiency classes, the better, and the higher the number of energy efficiency ratios, the better.

The lower the number of energy efficiency grades, the higher the energy efficiency ratio of the air conditioner, for example, the theoretical work efficiency of the air conditioner with energy efficiency level 1 is greater than that of energy efficiency level 3.

The higher the energy efficiency ratio, the higher the theoretical efficiency of the air conditioner, and the greater the cooling capacity provided on the basis of the same power consumption, and the corresponding power saving.
