Does Gree Air Conditioning really master the core technology?

"Master the core technology", in fact, this sentence can be heard from Jackie Chan for the longest time, and the direct impact after he said it is kowtowing. Poisoned by the advertisement of Wang Ba shampoo, just smiling. From the perspective of Gree, use this sentence to make a strategic layout. This must mean something.

First of all, answer what "mastering the core technology" means. In fact, science and technology is just a generalized solution of Gree, which is explained by the manufacturing process of air conditioners and the R&D and production of air conditioning components. The advertisement says that "mastering core technology" is higher than "mastering core components". So what we are discussing now is whether Gree has mastered good manufacturing technology and air conditioning components.

The production process, this is hard to say, and everyone does not understand. Let's just say nothing, someone's air conditioner is broken. To say that he is not good is not to master it. To answer this process from the yield rate, Gree's shipping yield rate is generally above 96%. (Actually, this should be true, but the water content in the company should not be lower than 98%. This can explain why some people say that my air conditioner is just not good. Then I can only say that you won the lottery. This rate of return in home appliances is high. Another six years of free maintenance is not just talk.

Let's talk about several main components of air conditioning. Compressor, motor, condenser. You can take down these air conditioners in your house and see if there are only worthless shells and small parts left. Compressor Gree has a wholly-owned company, Lingda Compressor. Not the best in the industry, but Samsung of Bangzi and Hitachi of the island country. Motor, Gree has a wholly-owned company Kaibang Motor. It is also above average in the industry. Condenser, the simplest, is directly a branch of Gree. Completely produced and sold, not for external supply. Gree can produce these main components by itself. This shows that he has controlled the overall situation.

To sum up here, Gree said that "mastering the core technology" is an advertisement, not a gimmick. Advertising is widely advertised, not exaggerated. What Gree wants to promote here is that he has a good production process and the production and research of components.

What is the core technology? It turns out that a beautiful one has been used for more than ten years. When the inner shell was yellow and the decoration was unsightly, it was taken down for grandpa to use, without even adding fluoride once. One Hisense followed me around four times, sent it to grandpa with beauty, and then added fluorine once. Gree's internal machines are always watertight, so Gree is not considered. I bought an air conditioner after the renovation. Galanz's two machines were only over 3,000, and only one Gree took two seconds. It has been used for two years now, and it is quite good, except that the internal machine is not good-looking. Who cares, as long as it's cool, who has nothing to do with an air conditioner?

Don't forget who invented air conditioning. As early as many years ago, the US imperialists and Japan basically patented key technologies. Therefore, unless someone completely transforms an air conditioner (with different principles), it can't bypass other people's patents at all. This also applies to most things in cars, televisions and computers. So advertising is ok, but the brand-new invention is not bragging and plagiarism! Where is the country? Scientific and technological invention is the most critical place!

Gree has mastered the core technology. The compressor was bought by Zhuhai Lingda Compressor Factory acquired by Gree, specializing in the production of low-end compressors. Most of the high-end air conditioners use Guangzhou Hitachi compressor, which is also called Dasong or Lingda. I suspect that the quality is poor and I dare not call Gree for fear of smashing my own brand. There are several comparison charts with Hitachi. Hitachi uses double row heat dissipation, Gree uses single row heat dissipation, Hitachi uses environmental protection refrigerant 4 10a, Gree uses r22 refrigerant that destroys the ozone layer, and there is electricity-assisted heating with huge power consumption.

I don't know if Gree Air Conditioning has mastered the core technology, but the installation and debugging of Gree Air Conditioning is absolutely first-class. As the saying goes, air conditioning is good, three points of quality and seven points of installation. Seriously, Gree told me to spit out the price. I think Gree is the only domestic product that can compete with Mitsubishi Heavy Industries and Daikin.

As an employee of a compressor factory, I can tell you that Gree's compressor stator, that is, the coil inside the motor, is provided by Japanese companies, which does not necessarily mean that Gree can't make it. There are also ordinary household small air conditioners and rotary compressors. At present, there are only two kinds, one is Japanese brand Daikin, and the other is outside Daikin. Daikin has a rotor patent, so the rotor structures of other brands are the same, Gree, Midea and Mitsubishi.

The long-term sustainable market result is the test standard, and the number of R&D teams, R&D costs and the number of patents are the supporting factors. Judging from the results, Gree has been recognized by consumers for a long time, and I feel good myself. The R&D team and cost support Gree are in the forefront of the industry and even China enterprises, as are the number of patents. However, there are many kinds of patents, such as packaging patents, technology patents and intellectual property rights. Some patents are not core patents unless they are technical, so the number of patents is not good. Many companies claim to have many patents, such as one meter in the mobile phone industry, but how many core patents are there? Gree's patents are mainly based on core patents, so Gree does master the core technology!

A few days ago, I went to the client to repair the server, National Astronomical Observatory. I looked up and saw Gree air conditioners everywhere, and I smiled. Why is Miss Dong so confident? Gree air conditioners are more expensive than other brands. It turned out to be a ZF procurement route. Hehe, anyone who has mastered the core technology is obviously a big eater. I remember that once Miss Dong accused Midea of air conditioning and cheated in the tender. What about herself? Air conditioners and compressors all rely on mechanical manufacturing technology, and even a ballpoint pen core can't be made. What is the core technology that Miss Dong has been talking about? It is nothing more than a high price and a high rebate. Every penny of financial money is paid by the people.

Although I don't understand the principle of air conditioning! My guess can be discussed! China is a big exporter of white goods in the world! First, the technology content is low! Still cheap, no profit! Just take a test! Speaking of technology, I think so! Foreign core technology also uses a patent knowledge money! Why is Gerry's air conditioner ranked first and central air conditioner not ranked? It is because foreign profiteering industries make their own money! Small profits to China! It seems that China exports so much, and the net profit is almost the same as the technology transfer fee to others! You see, the China missile was successfully launched, and the plane is advanced, which is actually similar to China's concept car! Looking at the fact that world leaders have been mass-produced, you ask where China's experiment was successful! That's just one or two core components of stowaways! Why didn't China dare to wage war easily? One is that we may have nothing! The second is that our biggest enemy is our own people! Sharp domestic contradictions ... that's all I have to say.

What is the core technology? Copper, iron and plastic? It used to be a compressor, but now it's not technology to modify someone else's compressor. Now it's mainly chip CPU. I have never heard that a domestic chip is independently developed. Using other people's frameworks and baseband is not independent research and development, just like many domestic CPU manufacturers, just show you a report.

Are those domestic self-developed mobile phone CPUs really self-developed? Recently, domestic chips have become a hot word on the Internet. Under the general trend of "patriotism", they often flaunt "independent research and development". From the "Godson" of the desktop platform to the later server platform. "Independent research and development" seems to be a more valuable word than "domestic products", and there is always an illusion of cheating money. But it looks a bit fall in price, even a bit ridiculous. What did you say?/Sorry? Today's cold knowledge, let's talk about the independent research and development of mobile phone processors. On the surface, the mobile phone processor is divided into three parts: CPU, GPU and baseband. Of course, there are many RF chips, cache units and other accessories on the motherboard. General manufacturers will enter the independent research and development stage from CPU and GPU. Self-developed CPU: At present, the CPU of almost all mobile phones on the market is based on ARM. ARM is a well-known semiconductor design company in Britain, and 95% of the microprocessors in the world are their descendants. Apple, Samsung, Huawei, Qualcomm, MediaTek and Xiaomi Songguo are all based on ARM. There are several differences based on ARM, one is the instruction set provided by ARM, and the other is the micro-architecture provided by ARM. The instruction set developed by ARM company is called ARM instruction set, which also develops specific microarchitecture. Take chestnuts for example. Cortex-A73 and Cortex-A53 are both microarchitectures of ARM. At present, only independent micro-architecture R&D capability can be considered as a real self-developed CPU enterprise. Here, let's explain it directly with an example: because the ARM instruction set and Cortex micro-architecture are directly applied, it is not independently developed. Apple once considered buying ARM, but in the end the latter fell into the hands of Softbank. ② Qualcomm Xiaolong processor: Kryo eight nuclear improved based on Cortex-A73, which uses the instruction set of Cortex-A73, but uses a self-developed micro-architecture, which is generally considered to be self-developed. To be honest, it is not easy to make a micro-architecture by yourself. It is necessary to coordinate the cooperation between the main components internally to obtain the best performance. Being able to generate collaborative solutions is a relatively high-end capability in the industry at present, and both Qualcomm and Samsung have this capability. At present, there are several types of mobile phone processor GPUs, such as public Mali series of ARM, PowerVR series of ImaginationTechnologies and Adreno series of Qualcomm. There used to be NVIDIA's Tegra "nuclear bomb", but it has withdrawn from the mobile field. By the year of 20 17, among all the manufacturers that produce and sell processors, only Qualcomm can be regarded as a self-developed GPU, and the rest are basically directly appropriated from the public version and then modified. As a public GPU, Mali GPU of ARM has some special circumstances: ① Samsung Exynos processor has embarked on the road of "low frequency multi-core"; ② Huawei and MediaTek are "less nuclear and high frequency" schemes; ③ I heard that Xiaomi's pinecone processor will also choose the "less nuclear high frequency" scheme. Theoretically, GPU is dominated by low-frequency multi-cores, and its performance is better than its output. PowerVR's position as a big manufacturer of Apple's Royal GPU solution cannot be ignored. The upcoming Helio X30 also uses PowerVR GPU, and its actual performance is expected by the industry. You think building a processor is that simple? Xiao An does not criticize "domestic products", but looks at the essence through phenomena. Don't kill or deny. Think too much, the whole processor has a lot of ISP DSP signal baseband and so on besides CPU and GPU.
