Daikin, Japan, has been using air conditioning for a long time. However, China didn't start producing and selling air conditioners until 2002, because when 1996 Daikin entered China, there were more than 400 air conditioning enterprises in China, and the competition was too fierce, while there were relatively few commercial air conditioning enterprises in China, so Daikin started with commercial air conditioning. But Daikin's home air conditioner is also great.
