How much electricity can be saved by Level 1 and Level 2 energy efficiency air conditioners

Energy efficiency ratio = cooling capacity Power consumption, machines with the same cooling capacity have 1-5 levels of energy efficiency ratio, respectively.

For example, if the cooling capacity of the machine is 3500 watts, the power consumption of the first-stage energy efficiency machine is 3500 watts, and the power consumption of the second-stage machine is 3500 watts, which shows that under the same cooling output, the power consumption of the first-stage machine is 1029-1094=65 watts less than that of the second-stage machine, that is, if the compressor works continuously for one hour, the first-stage machine consumes less electricity than the second-stage machine. Level 1 energy efficiency machines are the most energy-efficient, but ** is also the most expensive, level 5 is the cheapest, but low-energy efficiency machines will be banned from sale in the country, from the perspective of cost performance, it is usually more appropriate to buy level 2.

Hello, according to your question, my ** explanation is as follows:

Let's take a look at how much electricity is saved by the air conditioner at home and how much electricity is saved.

The energy efficiency ratio of air conditioning products was promulgated in 2005 and divided into 5 grades, which was upgraded to 3 grades in 2010. The calculation method is as follows: air conditioning refrigeration energy efficiency EER = cooling capacity refrigeration consumption power, air conditioning heating energy efficiency COP = heating heating power consumption.

Based on the energy efficiency label of the air conditioner, the accounting time of the refrigeration season is 1136 hours, and the accounting time of the heating season is 433 hours.

How much electricity can be saved by a first-class energy efficiency air conditioner?

Take the air conditioner as an example, a level 1 energy efficiency fixed frequency air conditioner power is 800 watts, and the level 3 energy efficiency fixed frequency air conditioning power is about 1000 watts, under the same circumstances, if you use it for 60 days in a summer, 8 hours a day, then an air conditioning season, ignoring factors such as ladder electricity prices, calculated with 5 cents per kilowatt-hour, the air conditioner with level 1 energy efficiency needs a total of 192 yuan, and the air conditioner with level 3 energy efficiency needs to cost 240 yuan, so that it can save 48 yuan in an air conditioning season. Level 2 energy efficiency compromise. Generally speaking, there are two seasons of air conditioning a year, and one air conditioner can be used for about 10 years, so that a total of about 960 yuan can be saved.

Level 1 energy efficiency air conditioning isn't just about saving electricity.

Not only to save electricity, the higher the energy efficiency ratio, the better the technical performance of the air conditioner, and the improvement of the energy efficiency ratio of the air conditioner can be improved from many technical aspects, such as replacing the low-efficiency compressor with a high-efficiency compressor, replacing the low-efficiency AC fan with a DC fan, appropriately increasing the air output of the internal machine, and the refrigerant charge is as little as possible. Inefficient air conditioners aren't cutting corners either.

But one thing needs to be mentioned: if the frequency of using your air conditioner is not very high, even if the energy efficiency ratio is high, the power saving effect is not obvious.

Another point is that products with a first-class energy efficiency ratio are generally more expensive than products with second-class energy efficiency.

There is no fixed difference in the power consumption of Level 1 and Level 2 efficiency, as they are measured according to different energy efficiency standards. The first-level energy efficiency standard requires that the energy efficiency ratio of the air conditioner is not less than, and the second-level energy efficiency standard requires the energy efficiency ratio of the air conditioner not to be less than.

Adjust the energy efficiency of the first level to be less than the energy efficiency of the second level of Zhiqingxun, and consume less electricity; 1.This energy efficiency is above and is the most energy-efficient product on the marketThe grade is a poor shirt.

The energy efficiency ratio for level 1 energy efficiency is , and the energy efficiency ratio for level 3 energy efficiency is. Through calculation, it can be seen that the refrigeration power of the level 1 energy efficiency air conditioner is 2600; The cooling power of the level 3 energy efficiency air conditioner is 2600. Both of them work for 1 hour, and the level 3 energy efficiency air conditioner consumes about 1 more degrees than the level 1 energy efficiency air conditioner.

The first-level energy efficiency of the air conditioner consumes less electricity than the second-level energy efficiency; Level 1 is the most energy-efficient product on the market, and Level 2 is the most energy-efficient product on the market. For every 1W of electricity consumed, the cooling capacity that can be obtained from the first energy efficiency and the cooling capacity that can be obtained by the second energy efficiency.

The energy efficiency ratio of an air conditioner is generally calculated by the cooling capacity and its rated power, and the calculated number is its energy efficiency ratio by dividing the cooling capacity by its rated power; Among them, the energy efficiency ratio of level 1 is above and is the most energy-efficient product on the market; Level 2 is level for level; The level 5 energy efficiency ratio is the market entry threshold.

In summary, the magnitude of the energy efficiency ratio value reflects the energy savings of different air conditioner products. 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. The energy efficiency label on the air conditioner makes it easy to "recognize" the energy-saving "star" from the many air conditioners, just by looking at the product grade marked on the arrow on the right side of the label

Level 1 products are the most energy-efficient, and Level 5 is the most energy-intensive. It should also be reminded that only the label is considered energy-saving air conditioning.

For the same 1 HP air conditioner, the cooling capacity is 5000W, and the cooling power is 2000W, then the energy efficiency ratio is the cooling capacity Refrigeration power 2 5;If the cooling capacity of another air conditioner is 5000W and the cooling power is 1500W, then the energy efficiency ratio is 3 333, then the latter is more power-efficient than the former, and the energy efficiency ratio is such that the higher the value, the more power-saving.

2. So, how much does level 1 energy efficiency save compared to level 3 energy efficiency?

Generally, the air conditioner with level 1 energy efficiency is thousands more expensive than the level 3 **, so how much electricity can level 1 save compared with level 3? Let's take fixed-frequency air conditioners as an example:

When the cooling capacity of the air conditioner with level 1 energy efficiency reaches 3000W, it consumes about 0 83 kWh of electricity per hour, while the level 3 energy efficiency consumes nearly 1 kWh. If the air conditioner is used for 5 hours a day, then at the end of the day, the level 1 air conditioner saves 0 85 degrees of electricity compared to the level 3 air conditioner, and 120 days in a summer, it is 102 degrees of electricity.

If we calculate according to the household electricity bill, if the electricity is 0 8 yuan, then the electricity cost saved by level 1 compared with level 3 in the whole summer is: 102 0 8 81 6 yuan.

A level 1 energy efficiency air conditioner is at least 1,000 yuan more expensive than a level 3 air conditioner, so if you only use the air conditioner in summer, how many years will it take to save this 1,000 yuan?

We divide 1000 by 81 6 equals 12 years, and the result is obvious. All things considered, if you buy an air conditioner, you can also choose an energy efficiency one.

How much electricity can be saved, the important thing is to look at the energy efficiency ratio.

The energy efficiency ratio of air conditioning is actually the ratio of "cooling (heat) to output power", the higher the value, the same amount of refrigerant gas, the smaller the power consumption, the more power is saved. In layman's terms, the energy efficiency of an air conditioner is how much cooling and heating are produced by consuming the same amount of electricity, and the more energy efficient the air conditioner, the more electricity it saves. Therefore, air conditioning energy efficiency is an important parameter to measure the performance of air conditioners.

Taking inverter air conditioners as an example, the energy efficiency ratio of more than 1 level, above 2 levels, and above 3 levels. According to the data of the National Monitoring Center, the average energy efficiency air conditioner of the first level can save about 8% of the electricity of the hood state than the second level. A 1500kw h 2 hp air conditioner is calculated based on an average cooling time of three months a year and 4 hours a day, and the energy efficiency of the first level saves nearly 50 kilowatt-hours of electricity compared with that of the second level.

The above table is the corresponding table of the new energy efficiency grade index, and the energy efficiency ratio of the corresponding level of cooling capacity, this figure can also be seen directly on the label.
