[PConline] There is no doubt that now everyone's daily life has been inseparable from a variety of home appliances and small appliances, so everyone will have the experience of buying appliances, do not know if you have the same concerns as Xiao Bian: " When purchasing appliances, in the face of energy efficiency grades and prices, often one has to worry about which one to choose first?â€
All kinds of home appliances do give us a lot of convenience. In the process of purchasing home appliances, we often pay more attention to the product's power consumption (energy efficiency rating) and price. In recent years, the country has called on everyone to build a conservation-minded society. Starting from oneself and saving all resources around, it can be said that saving has become a kind of fashion.
About China Energy Efficiency Labeling
What is the Chinese energy efficiency label?
The energy efficiency label is an abbreviation for energy efficiency label, which refers to an information label indicating the energy efficiency rating, energy consumption, and other performance indicators of energy-using products, and provides necessary information for the purchase decision of consumers (including governments, enterprises, and individuals at all levels). To guide and help consumers choose energy-efficient products. After more than 20 years of development, the energy efficiency labeling system has been continuously improved, and the types of labels have also continued to increase.
China Energy Efficiency Label
The energy efficiency rating is a classification method that represents the difference in the energy efficiency of household appliances. According to the relevant provisions of the national standard, China's energy efficiency label currently divides the energy efficiency into five levels. Level 1 indicates that the product's energy saving has reached the international advanced level and the lowest energy consumption; Level 2 indicates that the product is more energy-efficient; Level 3 indicates 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 lower than the market average; 5 is the product market access index. Products below this level are not allowed to be produced and sold. Currently mainstream products in the market can all reach level 3 or above. Level 5 energy consumption products are facing elimination.
Which appliances have Chinese energy efficiency labels?

In the past, many consumers could only know the power consumption parameters of the product by checking the nameplate or the manual of the product when purchasing a home appliance, which is very inconvenient. In order to solve this situation, in order to solve this situation, as early as in 2005, relevant departments began to carry out research and promotion of energy efficiency labeling. China's earliest energy efficiency labeling began on March 1, 2005. At that time, the only products involved were refrigerators and air conditioners. Later, they successively joined products such as washing machines, electric water heaters, induction cookers, rice cookers, tablet computers, and microwave ovens. Some products, such as refrigerators and other energy-efficiency labels, have undergone several generations of changes, and the requirements for energy efficiency grades have also been continuously improved, which has become a form of energy efficiency label that people have seen so far.
User A: Does a home appliance with high energy efficiency level really save power?
For the division of energy efficiency rating of home appliances, some netizens have expressed doubts that home appliances with high energy efficiency levels can really save power than home appliances with low energy efficiency levels. To this end, we may wish to do some math problems together.
LeTV 3 X50
Here, we take Leshi Super 3 X50 TV as an example. LeTV 3 X50 energy efficiency rating is three, the power is 130W, that is, under normal circumstances, watching one hour of TV programs continuously, the power consumption is 0.13 degrees Assuming 8 hours of TV usage per day, then the amount of electricity used by LeTV 3 X50 per day is 0.13 degrees × 8 hours = 1.04 degrees, and once a year is 1.04 degrees × 365 days = 379.6 degrees, calculated according to the municipal power supply of 0.61 yuan per degree, 0.61 × 379.6=231.56 yuan.
LeTV S50 Air FL2041
Let's take the same brand of music as the S50 Air FL2041 to make a comparison, music as the S50 Air FL2041 energy efficiency rating for the second, the power is 100W, assuming 8 hours of use of TV every day, then LeTV S50 Air FL2041 daily use of electricity is 0.1 degrees × 8h = 0.8 degrees, one year down is 0.8 degrees × 365 days = 292 degrees, according to municipal power supply 0.61 yuan per degree, 0.61 × 292 = 178.12 yuan. Comparing the two, one-year savings can save electricity 53.44 yuan.
We then took Mitsubishi Electric's MSH-DF12VD and Mitsubishi Electric's MSH-CE12VD for comparison to two fixed-frequency air conditioners. The DF12VD has an energy efficiency rating of two, cooling power of 1050W, and heating power of 1,130W. Assume air conditioners are used both in spring and winter ( Among them, cooling is used for 4 months in summer, and heating is used for 2 months in winter). Using 6 hours per day, the power consumption is 1095 degrees in one year, and the electricity rate is 1095 degrees x 0.61 yuan = 668 yuan.
The CE12VD energy efficiency rating for the three, cooling power 1135W, heating power 1210W, also assume that the air conditioning in spring and winter in two seasons for a total of 6 months, 6 hours per day, under normal circumstances, one year down the power consumption of 1253 degrees, electricity It is 1253 degrees x 0.61 yuan = 764 yuan. It can be seen that the electricity bill can be saved by 96 yuan a year.
Editing summary: Perhaps some friends will think that saving about 100 yuan in electricity bills in a year will not be a big deal, but as long as we carefully think about it, if every family can save a little, then the nation’s home appliance users The electricity saved for the country is huge. This is in fact very much in line with the state's advocacy of building a conservation-oriented society and sustainable development.
User B: The price of home appliance with high energy efficiency rating is higher than the price of the product. It is not cost-effective!
Among many netizens, some netizens believe that many home appliances with high levels of energy efficiency have relatively high prices. Even if they are not saved in terms of electricity charges, they are still not worthwhile. They prefer to buy cheaper appliances and have lower energy efficiency levels. A little bit.
For this purpose, let Xiaobian make an arithmetic question for everyone (please lightly spray it) and continue to take the data of the two fixed frequency air conditioners of the previous Mitsubishi Electric. DF12VD has two levels of energy efficiency, the price is 4,400 yuan, and the energy efficiency of CE12VD is three. The price is 3,700 yuan, where the price difference is 700 yuan. Using the data calculated previously, we can see that using Mitsubishi Electric's DF12VD can save electricity costs by 96 yuan per year compared to Mitsubishi Electric's CE12VD, and the air-conditioning's service life can generally reach 8 to 10 years. Therefore, the electricity cost saved is 96*8=768 yuan. This will make up for the difference in less than 8 years.
Mitsubishi Electric MSH-DF12VD
Some friends may think that the difference of 700 yuan will take 8 years to make up for the difference. Is this too long? In fact, for most consumers, they all hope that the service life of home appliances purchased will be as long as possible. Therefore, many consumers will agree that they will be able to return to this book in the long run. . To say a little further, the increase in prices and utility bills during the period of 8 to 10 years is also a very important factor. Moreover, in recent years, the state has introduced corresponding subsidy policies for household appliances with high energy efficiency levels. Consumer purchases can get subsidies and so on.
Mitsubishi Electric MSH-CE12VD
Editor's Note: In fact, on this topic, the discussion of consumers is also very fierce. Xiaobian thinks that publicly speaking public-private women are reasonable, but it is not worthwhile to purchase household appliances with high energy efficiency levels, depending on the user’s use. Customs, there is a “critical point†for the duration of home appliances. Within this “critical pointâ€, home appliances with a high energy efficiency rating will appear to be worthless, and once the use time exceeds this “critical point,†the cost savings will also be reduced. It will be quite a lot.
Editor's summary: Saving is an outstanding traditional virtue of our country since ancient times. When we purchase household appliances in the future, when we face the choice of energy efficiency rating and price, we may consider it based on our own usage of the household appliances. The above views of Xiao Bian may be one-sided, but Xiao Bian still believes that supporting environmental protection is worth promoting for both himself and the country. I believe that our vision will never be limited to immediate interests. As a careful Chinese, for the long-term interests, there will naturally be a scale!
