Midea air conditioner 1 night. The lie was exposed. "authoritative data" is not authoritative.
1 kwh difference between electric air conditioner and real air conditioner
This is a lie in the aperture of "energy saving technology". The media's questioning report on air-conditioning "one night 1 kwh" caused a shock in the industry, and the propagandists of air-conditioning enterprises moved out the concept of experimental data of energy-saving technology. But as long as you do a deduction, you will find that enterprises are so tossing, in fact, it is difficult to cover up the fact that they use the concept to "fool" consumers. After in-depth investigation, the reporter found that the experimental data of Midea air conditioner under the pretext of ECO energy-saving technology seems to be unable to withstand scrutiny. Air conditioning lies: "1 kwh for one night" transient "7 kwh"
On May 28th, Ms. Sheng, who lives in Changsha City, Hunan Province, complained to the media that a month ago, after watching Midea's advertisement, she bought a Midea air conditioner KRR-26GWBP3N1KB (1KB), but through the test, it was found that the maximum power consumption of this air conditioner reached "7KW a night". Ms. Sheng also said, "This air conditioner is very noisy. If the ECO energy-saving mode is set, the room will be like a' stuffy jar', making people unable to breathe. "
This beautiful air conditioner is installed in a room of about 10 square meter in Ms. Sheng's home. Ms. Sheng asked her husband to install an independent meter for this beautiful air conditioner. She wanted to convince her family that the advertisement of "one night 1 kwh" was true. But the test results prove that "every night 1 kwh" is a lie. On May 25th, the highest temperature in Changsha reached above 35. In the evening, Ms. Sheng even found that the power consumption of this air conditioner reached seven degrees a night. She is worried that as the temperature rises, the electricity consumption of this air conditioner will continue to rise.
In the face of Ms. Sheng's query that "1 kwh for one night" can't be done, Midea's after-sales staff responded that "1 kwh for one night" was advertised. Can you believe it? And this "every night 1 kwh" advertisement is the focus of recent market public opinion.
Conceptual lie: experimental data turns into store advertisements
The air-conditioning energy-saving concepts such as "1 night 1 kwh" and "1 kwh till dawn" have recently been called the most deceptive propaganda by the market. However, the relevant air-conditioning manufacturers said that these concepts can stand the double test of laboratory and practical use.
The shopping guide told the reporter: "1 night 1 kwh focuses on the energy-saving performance of air conditioners, which is the result of laboratory tests, and of course there will be deviations from the actual results." So, is it misleading to consumers or a reasonable consumer guide to label products with the test results set by the laboratory?
Experts from China Household Electrical Appliances Research Institute said that many consumers do not understand the meaning of laboratory data when buying products, but regard it as data in actual use. Of course, he does not deny that some manufacturers will use laboratory data to intentionally mislead consumers, especially at the level of promoters.
Is there a tendency for false advertisements to mislead consumers when experimental data are converted into advertisements? The industry said that it is difficult to define for the time being. Insiders expressed the hope that the relevant regulatory authorities will properly regulate the use of laboratory data for promotion and sales, so as to prevent individual manufacturers from misleading consumers by taking advantage of loopholes in laboratory data.
Data lie: "authoritative data" hides from cats and becomes "internal secret"
Is the advertisement of the beautiful air conditioner complained by Ms. Sheng, a netizen above, the authentic and authoritative experimental data?
When a media reporter suggested to the US that the actual power consumption may be different from the laboratory appraisal results, the US said that "there are laboratory data and third-party testing, which shows that authoritative experts are recognized." So, which authoritative organizations are authenticating these laboratory data?
The reporter saw in the propaganda materials about the key technologies of Midea's "one-night electricity" ecological energy saving that the research and application project of Midea's "one-night electricity" ecological energy saving key technologies was recognized as the highest international leading level through authoritative appraisal under the organization of China National Light Industry Federation. Midea's "every night 1 kwh" appraisal technical committee is led by Tao Wenquan, academician of Chinese Academy of Sciences and professor of Xi Jiaotong University, including 7 experts and professors from many universities and research institutes.
According to media reports, Professor Tao Wenquan said that he was not sure whether this appraisal was authoritative.
According to an article published by Midea official website, in the evaluation process organized by China Quality Certification Center (CQC), Midea's air-conditioning "every night 1 kwh" ECO energy-saving series products became the first products in the air-conditioning industry to pass the national "software safety evaluation". However, as of May 2 1 day, Midea has not provided relevant authoritative reports to the media, and said that the relevant reports are "internal technical materials", which will not be made public in principle, and only quality inspection and industrial and commercial departments can consult them.
The lie of 1 kilowatt-hour air conditioner was punctured, followed by the lie of experimental concept, the data authority of the concept lie was questioned, and the rhetoric of "internal secret" appeared. After deduction, it may explain why such a large air-conditioning company in Midea refused to publish an authoritative testing agency, because … lies are linked! This explains why in recent years, "1 second boot, 10 hour continuous use of tablet", "52-day fan" and other misleading advertising layers are endless, because ... under the aperture of "energy-saving technology", no one can catch a liar!
The authoritative certification of Midea's recent publicity;
On September 23rd, 2008, Midea Air Conditioning Co., Ltd. took the lead in obtaining the first energy-saving certification certificate of inverter air conditioners in China and the first energy efficiency label in the industry issued by China Quality Certification Center (CQC).
2010 65438+1October 29th, Midea's air conditioner was the first in the world to obtain the North American safety certification of UL fluorine-free environmental protection inverter air conditioner.
On July 3, 20 12, Midea's all-DC inverter air conditioner took the lead in passing the "Long-term Energy Saving Assessment of Air Conditioning" in China.
Midea's air conditioner "every night 1 kwh" ECO energy-saving technology has passed the inspection and verification of national professional institutions on September 201February, and has applied for a national invention patent; 20 12 12 was rated as "international leading" by the expert group led by academicians of Chinese Academy of Sciences.
In May, 20 13, in the evaluation organized by China Quality Certification Center, Midea's air-conditioning "every night 1 kWh" ECO energy-saving series was put up with KFR-26GW/BP3DN1Y-KB (1), becoming the first air-conditioning industry to pass the national "software safety evaluation". According to the technical experts of China Quality Certification Center, the future "software security" evaluation project will soon become the CCC certification standard commonly used in the industry.
Recently, the evaluation of 20 12 high-tech products organized by Guangdong Science and Technology Department has ended, and Midea air conditioner "1 degree for one night" ECO full DC inverter air conditioner is among them.
skill
1 kwh is 1000 watt/hour, that is, the electricity consumption of electrical appliances with power of 1000 watt for one hour. According to industry estimates, a room of 20 square meters is equipped with an energy-efficient 1 air conditioner (the lowest power household air conditioner), and the motor consumes 600 watts for one hour and 2.4 kilowatts for four hours.
Midea's air conditioner "electricity once a night" quoted experimental data and was accused of false propaganda.
With the arrival of the peak season, the air-conditioning industry has changed dramatically. Yesterday, air-conditioning energy-saving concepts such as "1 night 1 kwh" and "1 kwh till dawn" suddenly caused a storm, and some market voices called them "fudge"; However, the relevant manufacturers are unfair, saying that they can stand the double test of laboratory and actual use.
Yesterday, the reporter found that almost every air-conditioning company focused on the concept of energy saving. Among them, Midea inverter air conditioner mainly focuses on "night 1, 1 kwh", and Oaks air conditioner "dawn 1 kwh" is similar. The reporter noticed that the publicity pages are all marked with "use under certain conditions" or similar tips, but they are basically in the corner of the publicity materials, and the font is small. Previously, Gree had announced the launch of "8 nights 1 kwh" air conditioner. Users are supposed to use the air conditioner for 8 hours every night, and the minimum operating frequency of the air conditioner is 15W. The cumulative electricity consumption for 8 nights is only 0.96 kWh, which is less than 1 kWh. However, the reporter did not see this product in many stores.
Is it misleading to consumers or reasonable consumer guide to label products by using the test results set by the laboratory? Wu Zhidong, deputy chief engineer of refrigeration industry expert Weikai Testing Technology Co., Ltd. and deputy director of refrigeration product testing institute, said that the performance of air conditioners is greatly affected by environmental temperature and humidity. In order to make the products of different enterprises comparable, they must be tested in the laboratory of professional testing institutions. Measuring in the laboratory is an internationally recognized fair and reliable way, and it is also a responsible way for consumers. "It's like a car with a nominal 6 liters of gasoline per 100 kilometers is usually more fuel efficient than a car with 9 liters of gasoline per 100 kilometers."
It is reported that the data promoted by electrical products or other products on the market are generally based on laboratory test data, which can be verified by consumers looking at some promotional materials in shopping malls. When the national and local technical and quality supervision departments spot-check products, they also send them to relevant laboratories recognized by the state for testing, and make judgments according to the test results.
Second, is the test environment setting consistent with the actual use conditions? Wu Zhidong said that in order to make the test data more universal, the test laboratory setting data will generally be set according to the environmental conditions in most parts of the market. The outdoor ambient temperature at night in summer is below 30, which is in line with the actual climate conditions in most parts of China.
Some consumers said that the purchase of air conditioners attaches great importance to energy-saving indicators. For the energy-saving air conditioners promoted by various manufacturers, the focus is not on their publicity, but on the actual use effect and word of mouth. Some insiders said that air-conditioning enterprises in China should compete with each other in a down-to-earth manner, so that their core competitiveness, including energy-saving technologies, can stand the test of practice, and any spoiler and false propaganda will not last long.
Fake! In order to turn it on once a night, it is like this: the temperature is set at 27 degrees, and the air conditioning temperature sensor performs self-inspection. When the indoor temperature is 24-26 degrees and the outdoor temperature is 25-27 degrees, then the outdoor machine is not working, only the fan hanging indoors is working, and its power is only 20 watts, so turning on the air conditioner for one night is equivalent to turning on the fan for one night, so don't turn on the power at all! If the set temperature is between 16 and 23 degrees, it will consume several degrees of electricity in one night!
Originally, the slogan of Midea air conditioner was "only one degree of electricity every night", but later it was fined by the State Administration for Industry and Commerce for false propaganda, and the slogan became "as low as one degree of electricity every night", so I was happy. Chinese characters are really profound, so I changed a word. The misleading effect has not changed, but it meets the requirements of the advertising law and the State Administration for Industry and Commerce. Damn it.
As a graduate majoring in refrigeration, I can tell you exactly that it is impossible for ordinary families to use electricity once a night under normal circumstances. As low as one degree, it is the data of the laboratory. What is the concept of laboratory? There are many enthalpy difference laboratories in the factory. What is the insulation condition of these laboratories? And what is the wall of our house, and how is the insulation effect? Just compare it. Moreover, ordinary rooms have large windows, which have poor thermal insulation performance. The vacuum degree of double-layer glass can't reach, and the heat dissipation is very fast. In addition, the electrical appliances in the room should dissipate heat, and the human body should also dissipate heat, so the room will soon heat up and need to be cooled continuously. Do you think it's possible to power on once?
In the laboratory, the insulation effect is good, and they are all special foam insulation materials. There are almost no other appliances in it that heat up, and there will be no two people in it to dissipate heat. The air conditioner hardly works. It is ok to use electricity once a night in the laboratory, but it is unrealistic to transplant it to your own home. Therefore, "as low as one degree of electricity a night" is purely a fool for consumers. At that time, the TV station also interviewed Professor Wang Tiejun of our school once a night to talk about his views on electricity. The professor knew it was false as soon as he heard it, so he could only change the subject, which was quite embarrassing. This is what we were told in class.
Let's start with 1Hz. You may not have noticed that the inverter compressor has a minimum frequency. The lowest frequency of compressor imported from Japan I have seen is 1 1Hz, which is not a long-term operation. Domestic compressors, including joint venture compressors, can't reach such a low frequency, mainly because the compressor is not well balanced at low frequency and will shake badly. The frequency label of variable frequency compressor is from 1 to 120, but it can't be done in practice, and it can't give consideration to the dynamic balance of high and low frequencies, which is very harmful to the compressor, so the so-called 1Hz is a gimmick. The fixed frequency compressor is at that frequency and will not change, so the dynamic balance is much easier and the price is cheap.
I think the frequency conversion air conditioner is mainly to improve the comfort, adjust the operation of the compressor according to the different loads, and ensure that the room temperature will not fluctuate greatly. Energy saving is only an incidental result, which is equivalent to adding a head, but manufacturers and merchants bought bamboo slips and returned pearls.
Wandering around, can you focus on the service? The air conditioner at home is broken, and it took nearly half a month to fix it. It was repaired four times in the middle. The first time, I worked on the outdoor machine for a while, and it got cold. After three days, start the refrigeration, turn it off and turn it on again, and start to stop the refrigeration. Unplug the power and turn it on after a few hours, but it's still not cold. I called customer service again, and the maintenance master came the next day. After checking for a while, I said that the electrical box was broken and needed to be replaced. All the accessories of Gree should be sent to the headquarters, and I need to wait. I said that the child is only 4 months old, which is very urgent for me, really urgent. The parts arrived the next afternoon, and the maintenance master came around 7 o'clock. After changing the electric box, refrigeration still won't work. I said the valve should be broken and the coil needs to be replaced. I said hurry up. The children are beginning to get prickly heat. The master said it's urgent now, but it depends on the delivery speed. Then the next day, the outdoor temperature soared to 40 degrees and stayed up all morning. In the afternoon, I called the local maintenance customer service and said that the parts had not arrived yet. Priority was given to maintenance, and they did not arrive at night. I waited for another day the next day, and made several phone calls in the middle, saying that nothing had arrived. I repaired it as soon as I arrived, so I couldn't help it. I went to stay with my relatives for one night. I called twice the next morning. The first time the parts didn't arrive, I called customer service after 9 o'clock. The customer service said that the parts arrived, but the maintenance master sent them out, so I had to go the next day. I said no, the promised parts are given priority for maintenance and must be repaired for me on the same day. The customer service said that the instructions had been given and it would be repaired the same day. Until seven o'clock in the afternoon, I called several times to ask them when the maintenance master would arrive. The customer service said that the master was outside and couldn't tell what time it was. He didn't answer the phone call to the master, but he was working. I said that the air conditioner repairer would answer the phone as soon as it rang, but the customer service would not answer it when it called. Call me quickly and tell me the time. Last time I called, I was in a hurry. What time can you give me? It has been repaired several times, but it has not been repaired. Can't you find a good reason? Then the customer service said a lot, don't worry, it's useless to worry, the masters are working high above the ground, it's not safe to answer the phone, and so on. What is the reason why all the masters who come to my house are brave? Isn't it aerial work on more than ten floors? Why is the master squatting on the outdoor machine and making a direct phone call? I hung up in a rage, called Gree 400 to complain, and came to repair it in less than 20 minutes. I have a classmate who makes refrigerators. He said it was similar to the principle of air conditioning. Check whether the filter is blocked without refrigeration. After the maintenance master came, I asked him to check the filter screen. Master said he didn't check it. Check it this time. Replace the valve body coil first, then try it without refrigeration, and then check the filter and tell me that it is blocked, but the filter is under the outdoor unit and it is difficult to repair. Let me ask Spider-Man to take down the outdoor unit and repair it. I said, since it's so easy to go wrong, why isn't it easy to fix anything? This is a design problem. The maintenance master said to give it a try, but later it was dismantled and repaired. It was finished around 10 in the afternoon. It's annoying, the most disgusting maintenance!
Midea's advertisement: "The electricity is as low as one degree a night". Why do so many people spray?
Gree advertisement: "Give light to energy, without electricity bill". Why didn't anyone ask if it was true or not?
Midea's air conditioner is electrified once every night, which is the premise. It seems that electricity is turned on once a night when the outdoor temperature is 29, but there is no need to turn on the air conditioner when the outdoor temperature is 29. So, you know, it's not false propaganda, but it's not much better than false propaganda.
In a closed space, it should be an absolutely closed space. This is my understanding. Keep the temperature at 26 degrees, test results! But in reality, we may not be enough 1 degree a night, but it is also very energy-saving.
Many people may say that the advertisement of Midea is a bit extreme, but Midea just wants to prove that its beautiful air conditioner can save electricity.
I remember it seems that Midea explained in official website that only under experimental conditions can the indoor temperature reach the environmental protection temperature of 26 degrees, which is the result of specific environmental tests, but the actual situation has been achieved, which also shows that Midea's air conditioning is very energy-saving.
This advertisement proves that Midea's air conditioner is energy-saving and capable. Otherwise, it won't be hyped up. It is feasible in theory. In fact, we can't reach the experimental environment, but it is very good for consumers.
Don't worry about electricity once a night. Midea just wants to tell everyone that Midea's air conditioner is very economical and electricity-saving, and everyone can use it with confidence!
This is my personal understanding. I don't know if it's right. Welcome to comment. If there is anything wrong, please advise!
Gree air conditioner is not as beautiful as it is after it is sold. Buying an air conditioner means that after selling it, one air conditioner will be reimbursed for six years, and all of them will be replaced after six years. If the beautiful air conditioner can't be repaired, it can be replaced directly. Gree is rubbish. There are two grees in my family, and gree is very poor. I will never buy Gree again.
