Zhihu's many popular answers, as long as they are about central air conditioning, are very much torn, and this phenomenon is also quite common. Many "experts" who don't know their identities come up to brag about their products and think of ways to attack competitors' brands. As long as you have the heart to search, you will find a lot of black materials in various brands.
For example, Gree explosion, Toshiba bankruptcy, Daikin Jerry-building, Hitachi is Hisense, and mitsubishi electric's energy efficiency ratio is low. This series of posts abound
Why do many people like to talk about these things, even to the point of madness, because it is the easiest to talk about their own products, as long as they recite some words and tell some stories, as long as they make their own brands the best in the world, other brands are useless, so as to convince customers. The brand you choose is the best brand
This state is generally the sales state of newcomers who have just entered the industry. Many sales have just entered a company. First of all, they are trained by manufacturers. Many manufacturers' trainings, including our own participation in many manufacturers' trainings, also boast that their products are the best, killing all brands. As a manufacturer's point of view, he needs to convince the sales that the products he sells are the best, and accumulate the enthusiasm for sales. Product training is not particularly relevant
But many newcomers just started selling and didn't understand it very well, so they listened. He also had nothing to do with writing something on the Internet. As a result, the people were discerning and the owners were not fools. It was useless to write it. After this stage, I felt that these rumors were not true, so someone began to dismantle the central air conditioner.
I was in Tik Tok, and I often saw some online celebrity, which specialized in dismantling machines. Every day, some messy household appliances, refrigerators, washing machines and the like are dismantled, and the click-through rate and reading volume are very good. Until one day, we found that he began to talk about central air conditioning and floor heating. I think there is no problem. Everyone has his own opinions, mainly because what you said should be to the point. If he said something later, it seemed completely unprofessional to us, so I went to evaluate him and evaluated a few words that were also very pertinent. I didn't expect to be blacked out after a few words
, and then I felt that this matter was quite speechless. We thought it was incredible that you, a layman, had just made this thing, dismantled the central air conditioner and the boiler. In turn, he put a hat on us, saying that we were deliberately rubbing hot spots, and that we were selling by a certain brand
First of all, I never said that a certain brand was particularly good, and I have been sharing the installation with you all the time since HVAC. System design is very important, after all, HVAC is more about application
Secondly, I don't expect to get the truth by disassembling the central air-conditioning machine, which is mainly related to my previous work experience. I used to be a product design engineer, and I have stayed in state-owned enterprises and foreign companies. There are many engineers, including undergraduates, masters and doctors. Our daily work is to design engines, and I have done many projects myself, such as reverse development
. That is, I took a fancy to this engine, which was very good. I took it and took it apart, and did exactly the same thing. In other words, I copied it in a cottage
for example, the benchmarking project, that is, a certain brand of engine was well received in the market, and we had to benchmark it to see where the gap between us and them was
There were endless experiments and projects every day, and a lot of manpower and funds were invested. The laboratory was the engine simulation working condition, and I completed several projects independently. The engine fuel consumption optimization project in India market, because the emissions in India market are not quite the same as ours, and the three-year product development experience of Huawei's mini diesel generator set project
, let me understand several things
First, we should maintain enough awe for Japanese brands, no matter what industry. We can evaluate their brands, but we can't despise them. For example, Hitachi is Hisense. Toshiba bankruptcy, Daikin Jerry-building and so on
Many people actually find it hard to understand. In the automobile industry, engineers in China understand Japanese products, including some images of Japanese engineers, what kind of existence they are, and their engines can be much lighter than ours, including Italian engines, which are the heaviest. We talk about reducing costs and weight every day, so there is no need to do so. Others can do so lightly, saying Daikin cuts corners, as if air conditioning is as simple as getting a sheet metal.
In the whole world, the high-speed running parts of air-conditioning compressors in Japan are almost monopolized. Many people say that Daikin is not as good as Gree and Hitachi is not as good as Hisense. This statement is actually very ridiculous.
Second, about disassembling machines, what do many sales do? Disassemble machines, my brand is better than your brand's sheet metal. Disassembling a machine is a product benchmarking for a product engineer. A product is better than mine, so I want to benchmark it. This is a very professional thing. A layman can only see the sheet metal and parts foundry, but nothing else. Why?
1. If you judge the air-conditioning quality of the brand by the weight of sheet metal and brand, I think you can go to product development and be a product engineer. The logic of Japanese products is to give you the best and reduce the products to the lowest. No matter whether it is air-conditioning or automobile, its A-pillar will not break, and it can pass many safety grades, but its fuel consumption is low. What can you do? Still can't pass the safety level
2. Take apart the machine and look at the parts manufacturers. The sales name says that you can understand which manufacturer made the motor. In fact, the motor in each air conditioner is not made by the motor manufacturer. It just helps many brands to OEM, and each air conditioner manufacturer gives him different drawings. The technology of each air conditioner manufacturer is closed. The same motor factory makes different things. The OEM produces according to the drawings and materials specified by the air-conditioning mainframe manufacturer. When the mainframe is disassembled, you can only see a OEM logo, but the parameters and performance curves are invisible. The air-conditioning manufacturer considers that after you take this motor, for the supporting capacity of my entire air-conditioning equipment, this drawing I produced meets the expected effect for my entire system through various experiments, not to say that the so-called most awesome OEM products are found. Put together, it is the most awesome air conditioner.
3. If a layman comes to a conclusion about two products by disassembling them, and he puts forward an optimized scheme, you can be someone else's product engineer. You know, other product engineers, in the laboratory every day, pay so much for one air conditioner, and after they make it, their conclusion is not as good as the conclusion that you disassemble a machine today, so some people. Therefore, some people dare to evaluate the brand just by disassembling the machine. It can be said that they have no respect for people in the machinery industry, and they just take it for granted.
When our product engineers develop product experiments and do product benchmarking, the industry experience is accumulated from decades of experience, including data optimization and data analysis, which are constantly summed up. From the previous generation to future generations, from the horizontal perspective, it is based on the experience of the whole industry. For example, if the motor has any experience and the fan has any experience, the manufacturer of the industrial chain will sue the engineer. The engineer collects the experience and resources of the industrial chain to continuously optimize the products, which is not comparable to that of a layman by disassembling the machine. 4. The compressor of the central air conditioner runs at a high speed, and the working conditions of everything from high-speed operation are completely different. He needs to involve a lot of theoretical knowledge. In design, many principles need to be simulated, and many complicated softwares are needed. Air conditioners, like automobiles, return to comprehensive energy consumption and noise. Energy consumption refers to the energy consumption at all stages, and the comprehensive energy consumption and noise under various working conditions of low-frequency, intermediate-frequency and high-frequency operation. When you say that the sheet metal is thick or not, there are not many fins, which has nothing to do with us. What we need is comprehensive energy consumption and noise. In the eyes of the design department, there is not much concept of product cost.
What you call the thickness of sheet metal has nothing to do with us at all. We basically calculate that sheet metal is probably the most suitable, and all kinds of sheet metal are particularly good, because sheet metal is actually not much money, and the main thing is an index that affects the design department, not the cost, but the energy consumption and noise and its durability < P >, but the knowledge of energy consumption and noise is very advanced. I have done engine noise, turbocharger noise, and then I have participated in the noise of the whole vehicle, involving noise.
Those who have studied well in college and differential integral can learn with this foundation, and master students can learn with this foundation, and doctors can also learn. Those who have done well in the noise major in the country are basically master doctors, with very high income, very expensive equipment and very expensive noise simulation experiments.
Why do you say that the threshold of machinery industry is very high and the threshold of education is very high, and these people have to spend money? With such a high training cost, it must be invested in postgraduate students and doctoral students, and undergraduates can't go to school basically, unless a group of people can learn it very early. In such a high-level thing, what is it equivalent to asking a layman to dismantle the machine? It's probably the final result of an undergraduate student evaluating a group of master students and doctoral students. < P > Therefore, for us to keep enough awe of our products, I have no intention to disassemble the machine since I entered the business, and only amateurs go to disassemble it. What can you see from some people in various sales industries except the sheet metal and parts manufacturers after disassembling the machine?
I think the top brands in the world's top 5 are all good. As HVAC companies and distributors of manufacturers, we do our own installation and system well. If we compare our HVAC companies to chefs, the central air-conditioning equipment of each manufacturer's brand is equivalent to the ingredients, and the ingredients themselves are good. You should study your own skills, hone your knife work and the management of the kitchen team. This is the most important thing.
For the customer, he not only eats ingredients, but also needs to enjoy relevant services. How to improve customer satisfaction is also a matter for the dealer to consider. We simply don't have so much energy to participate in the product. Let the manufacturer study the product well, and everyone does his job. As a dealer, there is no need to disassemble this machine and study it. When you reach a certain level, you said that I should understand all the ingredients well.
At present, many people who don't understand are doing product comparison, which can win people's attention and get some short-term traffic. In the long run, this is a road of no return. As a dealer, it is important to improve their ability to respond to customer needs. If you are a media, you want to make money and eat traffic, then you should continue to do your disassembly.
