Air conditioning compressor competition, whose compressor is the most forced cold ＂heart＂？

　　Many people say that buying air conditioners means buying them, which is absolutely true. The quality and life of compressors determine the attitude of most people to buy, so what are the common compressor brands in the market? What compressors do these brands of air conditioners use?

　　Mitsubishi electric, founded in 1921, is currently one of the few manufacturers in the world that can produce all kinds of high-performance compressors. You know, in air conditioning, the compressor can almost be equated with the "heart" of air conditioning, an air conditioner. If the "heart" is not good, it will be worse in all aspects.

　　Because mitsubishi electric’s compressor is powerful and well-known, some air-conditioning manufacturers even use mitsubishi electric’s compressor as a publicity stunt, which shows how awesome mitsubishi electric’s air conditioners are.

　　In addition, mitsubishi electric’s frequency conversion technology can almost be regarded as the top full DC frequency conversion technology at present. Some people may not understand the use of this technology. Simply put, it is less energy consumption, improved energy efficiency and more comfortable body feeling.

　　Daikin, founded in 1924, is also a first-line brand of air-conditioning equipment manufacturers. Its main advantages are that it can be compared with mitsubishi electric’s double-rotor compressor, self-developed swing compressor and a Cleanlet intelligent cleaning series equipped with air-conditioning self-cleaning technology. Others, in terms of frequency conversion technology, although not as good as mitsubishi electric and Hehe, the overall performance is not too bad.

　　The world’s first research and development manufacturer of scroll compressor is also the only manufacturer that applies scroll compressor to split air conditioners. At the same time, it is the current first-line air conditioner brand manufacturer and the founder of full DC frequency conversion. It has the technology of "freezing self-cleaning" without manual intervention, and it also has a unique heating idea. It should be noted that Hitachi’s offline service ability can only be regarded as average because its market share in China is not large.

　　Panasonic

　　Panasonic was founded in 1918. The compressor is relatively not as strong as mitsubishi electric, and the noise is slightly higher, but the overall performance is not bad. For many years, the sales volume ranks first in the Japanese household air conditioning market, and the temperature control technology is strong, which can quickly cool and then control the temperature in a short time. In addition, the low-temperature heat storage technology far exceeds the commonly used electric auxiliary heating technology, but there is still a certain gap compared with mitsubishi electric.

　　Gree, as a big domestic brand manufacturer, has performed very well in the domestic and international domestic air-conditioning market, but our industrial foundation is relatively weak after all, so Gree can only achieve the level of self-produced compressor at present, and the scroll compressor is still not up to expectations, and there is still a certain gap compared with some top manufacturers.

　　Of course, Gree has been working hard to take the independent route, including chips and the like, and the internal structure of Gree is relatively fine, and the performance of quality and stability is not bad, and both low-end models and high-end models are basically involved in all aspects. As a domestic local brand, offline services also have great advantages compared with other foreign brands.

　　Midea’s main feature is energy saving. After reaching a cooperation with the special research and development of low-frequency technology, Midea has a strong and complete air-conditioning industry chain, and all aspects can basically be self-sufficient.

　　Founded in 1995, it is a large-scale Sino-Japanese joint venture specializing in R&D, production and sales of rotary compressors and reciprocating ball bearings for air conditioners. It is established by China Midea Electric Co., Ltd. and Toshiba Co., Ltd..

　　Midea not only performs well in the compressor, but also achieves high accuracy of 0.1HZ in full DC frequency conversion technology. Compared with Gree, Midea’s internal welding technology of air conditioners still lags behind Gree at present, and of course, the price is lower, but even so, both Gree and Midea are one of the few first-class air conditioning brands in China.

　　Haier, Gree and Midea are both domestic first-class air-conditioning brands. Haier’s air-conditioning performance is good, but compared with Gree and Midea, there is a big gap, which can be seen from the market share.

　　The lack of hard power, on the one hand, Haier does not have the ability to develop its own compressors at present, and the compressors are basically purchased from home and abroad. The DC frequency conversion technology still needs to be broken, and the overall performance is quite satisfactory. Of course, the self-cleaning technology is still very comfortable.

　　Haier machinery got the core technology through cooperation with Mitsubishi Heavy Industries in the early days, and the name of the air conditioning company was Mitsubishi Heavy Industries Haier. There’s nothing to say about the quality, such as fast refrigeration, high thermal efficiency, beautiful appearance, reasonable cost, frequency conversion and fluorine-free. Haier started out as a refrigeration manufacturer, and it is the first world famous brand in China, a Fortune 500 company, and it is manufactured all over the world.

　　Oaks also has no self-developed compressor technology, and its performance in frequency conversion technology is not particularly outstanding. Compared with other brands, Oaks is more like a resource integrator, integrating various resources together to form its own uniqueness.

　　Of course, many people don’t care about this. For most people, as long as the quality of air conditioners is passable and the price is low, it is a good air conditioner. It is precisely because of this that Oaks also occupies a good market share in China, with a sales scale as high as 10 billion yuan.

　　Hisense has invested heavily in frequency conversion technology. Although it only entered the air-conditioning market in 1996, it is one of the earliest brands to launch frequency conversion air conditioners in China.

　　Of course, even so, according to the feedback from the market, Hisense still has the possibility to continue to make progress in full DC frequency conversion technology. As for compressors, due to the lack of related technologies, it mainly purchases compressors from other brands, such as Hitachi, Hitachi, Hitachi, etc. At present, Hisense’s air conditioners focus on cost performance, and their performance is still acceptable.

　　

　　TCL has its own compressor technology. Before that, it set up a compressor company with Ruizhi. Although the performance of Ruizhi compressor is not excellent, its quality is still reliable. TCL also focuses on cost-effective air conditioners. It has many brands, and the middle and high-end aspects are also slightly involved.

　　Kelon was founded in 1984 and was acquired by Hisense in 2006. Although their businesses are relatively independent, because the technology is shared, the quality of air conditioners is actually similar. The main advantages are affordable, first-class energy efficiency, full DC frequency conversion and so on. The disadvantage naturally lies in the double-sided effect brought about by affordable prices, such as poor workmanship.

　　Changhong’s enterprises with a military background are highly skilled and generally used in materials.

　　Changhong invested 75% and Dongyuan invested 25% to set up Sichuan Changhong Dongyuan Precision Equipment Co., Ltd. Since then, Changhong has had its own compressor. When it was the hottest in 2007, Changhong TV left several warehouses, and all of them stopped working on the opposite air-conditioning production line. As a result, the compressor was still too late to produce, so others used their own compressors for low-end products and Haili (for high-end products)

　　Smart air conditioners like Xiaomi are partly manufactured by Changhong.

　　Xiaomi doesn’t have its own air conditioning factory, and basically it is OEM by other brands. The C series is OEM by Hisense, the A series is OEM by Changhong, and the X and Roufeng series are OEM by TCL. Then Xiaomi’s products, as we all know, basically focus on high cost performance and diversification of intelligence and functions.

　　Hualing was founded in 1985. In 2004, Midea became the first controlling shareholder of Hualing, so at present Hualing is a brand of Midea.
