When PConline is used to purchase household appliances, we often consider many factors. For household appliances or household appliances that consume large amounts of electricity, their energy consumption performance is definitely a factor that we will seriously consider, and we go to the store to buy Home appliances, will certainly pay attention to the various energy efficiency labels on household appliances. The small stickers on energy consumption are just a few of the important references for home appliances. It is an important reference to determine if a product is sufficiently energy-efficient. Let's talk about it. Some things about the energy efficiency of home appliances.
Regarding energy consumption, each has its own opinion
Everyone has different views on the energy efficiency of various types of home appliances. When consumers purchase home appliances, if they want to judge the energy efficiency level of a product, they generally can only roughly understand the energy efficiency of a product through some energy efficiency labels attached to the machine. Level.
Ads are easy to confuse you: For home appliances, especially those with relatively large power consumption, such as air conditioners and electric water heaters, some advertising words will also highlight the energy saving level of products, as we all know very well. "It's a little exaggerated, and the product may have advantages in terms of energy saving. But once a night, it is estimated that it will only be realized under very harsh conditions. At least every summer, when air-conditioning is used frequently, when the electricity bill is paid, Everyone knows how difficult it is to achieve one night of electricity. Therefore, for some dazzling ads, we still have to take a rational view, and ultimately we must look at products.
The price difference is not sure to be a good choice: buyers, the price is certainly the main factor for most people to consider, under the premise of adequate budget, if the two products can meet the demand for use, the difference between the two is not big, then choose energy efficiency The product with better indicators is definitely right.
If the difference is big, then you have to take a good look: Different products, an energy efficiency rating may bring different levels of price differences, such as refrigerator products, now can achieve a level of energy efficiency products are already very large, thousands of products There are also very many levels of energy efficiency products. For air-conditioning products, the level of energy-efficient products is not only small, but mainstream products with large market sales are generally three-level energy efficiency, and the number of products with the same number of horsepower, two-level energy efficiency and three-level energy efficiency products is in the range of 1,000 to 3,000. The difference between the range, level 2 energy efficiency and the level 1 energy efficiency products can even exceed 3,000 yuan.
The huge price difference will surely dispel many consumers’ thoughts of adding money to buy better energy efficiency products. And roughly estimate the use of home appliances, we attach importance to energy efficiency, nothing more than to be more energy-efficient, in the future can save electricity, if the price difference is too large, if a product is used for a few years, think about it is not absolute Cost-effective.
Do not care about energy efficiency, "I" only buy like: for consumers with a very adequate budget, the perspective is not the same, just buy your favorite, energy efficiency may not be their concern, for such consumption Those who Xiao Bian wants to say are, willfully buy it.
Different product energy efficiency labeling reference values ​​are different
The energy efficiency labeling reference values ​​of various household electrical appliances will be completely different. The only difference is that there will be a grading of 1, 2, and 3, and the reference value on the label will be completely different.
Refrigerator energy efficiency logo
Refrigerator: For refrigerator products, in addition to the conventional classification of energy efficiency labels, there is a 24-hour power consumption that is worth referring to. By giving the value, we can roughly understand the power consumption of this refrigerator for one day. When you buy a product, you'll know it.
Washing machine energy efficiency label
Washing machine: In the energy efficiency labeling of washing machine products, it is worth referring to the power consumption, water consumption, and cleaning ratio of a work cycle. If the conventional energy efficiency classification can meet your purchasing requirements, then some other parameters are also worth referring to. A bit, and it's equally easy to understand.
Air Conditioning Energy Efficiency Label
Air Conditioning: For air conditioner products, the products currently sold in the market are generally divided into three energy efficiency grades, and energy efficiency ratios, input power, and cooling capacity data are also given on the energy efficiency label. The energy efficiency ratio is the value obtained from the ratio of the rated cooling capacity to the rated power consumption. It can also be understood as the value of the ratio of the indicated cooling capacity to the input power. The higher the energy efficiency ratio is, the more energy the air conditioner will use.
Rice cooker energy efficiency logo
Rice cookers: We use rice cookers every day. In addition to conventional grading, the energy efficiency labels on rice cookers also have thermal efficiency values, standby power, thermal insulation power, and internal pot materials. The higher the value of thermal efficiency, the more likely the rice cooker will be. Power saving.
Microwave energy efficiency logo
Microwave ovens: For microwave ovens, there is also an efficiency value on the energy efficiency label. The higher the efficiency value, the more power the microwave oven consumes.
Electric water heater energy efficiency label
Electric water heaters: Electric water heaters are definitely a big consumer of electricity. There are a 24-hour intrinsic energy consumption factor and a hot water output rate on the energy efficiency indicator on an electric water heater. The 24-hour inherent energy consumption factor means that water heaters are not used. The ratio between the energy actually needed to set the temperature and the energy defined by the standard is the ratio of the water temperature. The lower the ratio, the better the insulation effect of the water heater. The value of the hot water output rate is also as high as possible. Under normal circumstances are greater than or equal to 70%.
LCD TV energy efficiency logo
Flat-panel TVs: Today, the popularity of flat-panel TVs is already very high. The energy-efficiency labels for flat-panel TVs are marked with the energy efficiency index of LCD TVs and passive standby power. The lower the energy efficiency index, the more energy-efficient TVs will be.
Summary: From the perspective of ordinary consumers, for energy efficiency labeling of home appliances, most people will simply look at the energy efficiency level. For other values ​​given, there is no concept and it is difficult to have a reference value. Xiaobian recommends that If you really pay attention to the energy consumption of the product, before you go to the store to see the product, you can do more homework and learn about the meaning of some of the values ​​given on the energy efficiency label of a specific product.
Energy efficiency leader is cold? Manufacturers may not buy it
In November 2015, the National Development and Reform Commission released three implementation rules for home appliance energy efficiency front runners on its official website. They are the Implementation Rules for the “Frontier Leader System for Household Refrigerator Energy Efficiency†and the Implementation Rules for the “Leader for the Flat Panel TV Energy Efficiency†System. 》, "Speed-control room air conditioner energy efficiency" "leader" system implementation details, these three rules are following the exit of the energy-efficient appliances subsidies policy in June 2013, the country announced the first appliance incentive policy. After more than four months after the policy was promulgated, the list of the first energy efficiency front runners was announced in the second half of this year.
Energy Efficiency Leader Logo
The first batch of selected list is divided into three major product categories, including refrigerators, flat-panel TVs, and air conditioners. Among the brands listed in the refrigerator category energy efficiency leader list include Haier, Haier Commander, Rongsheng, Midea, Casa Di, Little Swan and Aucma . The brands that were selected for the leader in the flat panel TV category were Skyworth, TCL, Konka, Hisense, and Le. China and Samsung are among Gree, Haier, Changhong, Midea and Haier .
From the first list of candidates, we can see that the categories selected for each category are basically domestic brands, and there are few international big names. Is the international big-name product not performing well in terms of energy efficiency? Obviously this will not be the case. First of all, the energy efficiency leader's policy only involves honorary awards and policy support, but policy support currently has no clear statement, which means that even if it is finally selected, there will not be any capital subsidy, and it is only an incentive policy.
For this kind of pure incentive policy, the manufacturers' enthusiasm is not high but also understandable. After all, with the conventional energy efficiency logo, this new logo title, the effectiveness of short-term promotion is also difficult to estimate. For manufacturers, declare energy efficiency leader looks This is a difficult and profitable thing for your own product.
Summary: It is certainly a good thing that the state uses policies to promote manufacturers to produce energy-efficient products, but manufacturers do not necessarily have high enthusiasm to participate in these new policies on energy efficiency. If the new policy is promoted in the early stage, if there are few products involved and consumers do not understand these new policies well enough, there will be no obvious benefit to both buyers and sellers.
What is Beijing energy subsidies?
I believe that many people on the e-commerce website will see that some home appliances will have Beijing Energy Saving Subsidy, so what kind of regional energy-saving subsidies is this?
Beijing energy subsidies will be marked
First of all, the subsidy time for Beijing's energy saving is from November 27, 2015 to November 30, 2018. It will last for a full three years. The target of the subsidy policy is Beijing's household registration personnel, active military personnel stationed in Beijing, and non-Beijing-based personnel with active residence permits and temporary residence permits outside the active military police. From a policy oriented perspective, this policy requires that you at least be in Beijing. Hold a temporary residence permit.
TV, refrigerator
Washing machine, air conditioning
Water heaters, range hoods
Energy Efficiency Mark 1 (subsidy 13%)
Energy efficiency label 2 (subsidy 8%)
Subsidy limit RMB 800 Air purifier subsidy 10% Subsidy limit RMB 800 Subsidy toilet allowance 20% Subsidy limit RMB 800 Yuan Bicycle subsidy 10% Subsidy limit RMB 800The categories of products that meet Beijing's energy-saving and emission-reducing commodity subsidy standards include TVs, refrigerators, washing machines, air conditioners, water heaters, range hoods, air purifiers, toilets, and bicycles. There are corresponding subsidies, and the only ones are the same. The upper limit of subsidies is 800 yuan. For consumers who can enjoy energy-saving subsidies from Beijing, when they purchase some large-scale household appliances, the subsidies can amount to several hundred, which is equivalent to playing a considerable discount.
Summary: For this kind of subsidy policy from the perspective of energy efficiency, the biggest benefit is undoubtedly to urge consumers to choose products with better energy efficiency performance, and to stimulate consumption in this area. Naturally, there will be more manufacturers willing to go to research and development to produce more energy-efficient performance. Good products, this can be regarded as a benefit to the people's policy, but there is a limit to the crowd who can enjoy the policy. Xiaobian, a commuter in Guangzhou, is also looking forward to when Guangzhou will also come to an energy-saving subsidy policy. Bicycles can also be subsidized. It is indeed a good thing.
Simple test to see if energy efficiency logo is reliable
Since the energy efficiency labeling is an important basis for us to judge whether the product is an “electric tiger†when we purchase home appliances, Xiao Bian has just come up with some products to test it simply to see if the reference provided by the real use and energy efficiency label is different. .
Refrigerator 24-hour energy consumption test
First of all, let's take a look at a thousand-dollar refrigerator product. This refrigerator product has achieved a level 1 energy consumption. The energy efficiency label shows that the 24-hour power consumption is only 0.48 degrees. From the logo point of view, this refrigerator is very provincial. electrical. What is the actual situation? Xiaobian used the power meter to test the refrigerator for one day. The power consumption displayed by the power meter was 0.57 degrees, and the difference between the energy efficiency label and the mark on the energy efficiency label was 0.09 degrees. The difference was not significant. Taking into account the different habits of daily use, If you frequently take refrigerator foods, the number of compressor starts will increase, and the power consumption will naturally increase. If you do not open the refrigerator all day, it is very likely that you will measure the value of the energy efficiency label.
One cycle energy consumption test of washing machine
Let's take a look at a washing machine product. This is an ordinary washing machine. From the point of view of energy efficiency labeling, the values ​​given for power consumption, water consumption, and cleaning ratio all have certain reference significance. Here focus on testing the power consumption of a work cycle, Xiao Bian to the washing machine into the five items, including jeans, cotton fabrics, using standard procedures for clothing washing. After washing, the power consumption displayed on the power meter is 0.09 kWh, which is very close to the 0.1 kWh of a work cycle on the logo. According to the number of clothes, the power consumption of a work cycle is basically 0.1 kWh. Floating.
TV energy consumption test
TV is also a household electrical appliance that we usually use regularly. The power of flat-panel TVs is now more than 100 watts. Xiao Bian this time pulled a 43-inch 4K flat-panel TV to test the power performance, because of the energy efficiency logo of LCD TVs in addition to the three energy efficiency levels, the reference value can provide only the LCD TV energy efficiency index and passive Standby power, the lower the energy efficiency index, the more power the TV saves.
Xiao Bian will continue to broadcast television for 8 hours and 35 minutes. The final display of power consumption is 0.39 kWh. The power of this TV is 100 W. In theory, running 10 hours will consume one kilowatt-hour, depending on the test results. The energy efficiency performance of this flat-panel TV is still satisfactory. Of course, TV's energy consumption is closely related to the dynamic performance of TV. Volume levels, different videos, etc. will affect the actual energy consumption. Therefore, the test results are for reference only.
Summary: From the actual testing of several products, the energy efficiency label is still worthy of reference, as long as we can correctly understand the numerical meaning of the energy efficiency label, we will buy products will be even more bottomed out. For some other electrical products, they cannot be tested one by one under the test conditions. When you buy appliances, if you really do not want to pay attention to various reference values ​​of energy efficiency labels, you can directly select energy efficiency levels according to your own budget. A good product will do.
Written in the final: on home appliances energy efficiency performance, many times only relatively energy-saving, such as air conditioning in the summer, in order to enjoy a more cool feeling, you must reduce the temperature accordingly, so that the air conditioning power consumption naturally goes up With the same enjoyment given to consumers, different products may not have the same energy efficiency performance. Therefore, understanding the energy efficiency label of various products will help us to purchase products. How do you think about how to buy energy-saving products?
