Which brand of central air conditioning is better, Gree, Midea or Daikin?

The core component of central air conditioning is compressor, and Hitachi is the owner of compressor patent. After the 20-year patent protection period of rotary compressor expired, the patent of scroll compressor was also collected by Hitachi. The performance-price ratio of Hitachi central air conditioning is still ok.

Daikin central air conditioning pioneer, Daikin, VRV series quality leverage, that is, the price is not close to the people, more expensive than Hitachi with the same configuration. The central air conditioning in the kitchen seems to be unique to Daikin, and Daikin's internal machine still has unique technology.

Gree, a rising star of domestic central air conditioning, is very competitive. But the biggest problem of Gree central air conditioning is that the compressor is subject to people. Therefore, the compressors of Gree Central Air Conditioning are universal compressors, including domestic compressors, Toshiba compressors, Daikin compressors, Hitachi compressors, rotors, double rotors and scroll compressors.

The heating function of Japanese central air conditioner is not as good as Gree's, because Japanese central air conditioner has no electric heater, and Gree has electric heater. Therefore, household central air conditioning heating is lever-type, that is, it smells like plastic when it is turned on, and it is baked with an electric heater.
