What core technologies has the very famous Gree air conditioner mastered?

I haven't heard of any innovation in air conditioning technology. I wonder why domestic brands such as Changhong don't advertise because Gree blows so hard, because they are all in business and air conditioners. Maybe they're all just busy living. With this technology, the power consumption of air conditioner is equivalent to a household light bulb. This won the National Science and Technology Progress Award and was stamped by the state. In order to compare the data better, the industry generally stays at the level of 10 Hz.

This is not to say that these two wires cannot be used as motors, but the requirements for stator matching, data calculation and lead welding are much higher than those of copper wires. Of course, the cost gap is also surprising. Of course, the technology required to make aluminum wires and copper-clad aluminum motors is much higher than that of copper wires. The dispute between Oaks and Gree has made the public curious about Gree again. In other words, the main advertising words for so many years have mastered the core technology. What are the core technologies? Whether it's over-marketing or genuine.

You can't tell the difference just by looking at it After installation, it is easy to know the quality of the air conditioner, the plastic shell, condenser, evaporator, refrigeration effect and the failure rate of installing a new machine, and then it is easy to distinguish. In 2004, it wholly acquired Lingda Compressor. Gree is the second largest shareholder of Shanghai Lihai Company (mainly engaged in air-conditioning compressors), and Dong Mingzhu is also the first beneficiary of Zhu Jianghong's technology. In addition, the motors and condensers related to air conditioning are also self-sufficient.

Third-rate technology is used in nuclear bombs, satellites, engines, gene medical care, industrial robots, 5G communication, etching machine, large aircraft and third-rate chips (GPU chips, AI chips). Gree, civil air conditioning is the core technology rather than the cutting-edge technology. Artificial intelligence will be very common in the future. Gree's approach is too overbearing, I can't get used to it, and it's a bit of Trump. At that time, Gree bought Lingda compressor and then spent a lot of money to produce it, which may be a card of Gree. However, Gree Lingda compressor is not the best in the industry. On the contrary, the performance of compressors in mitsubishi electric is outstanding.
