In ancient times, there were three mitsubishi electric double-fan frequency setters PUH-3YG6 (outdoor unit model) made in Japan, but now it is rare (I remember that Jinsong, a small air-conditioning factory in China, copied their outdoor units). The internal machine is the same as the old Chunlan. There are many imitations of old Chunlan air conditioners in old mitsubishi electric, hence the name of Mr Slim's commercial machine in mitsubishi electric. Year: about 1990- 1993 (the impression is that it is contemporary with mitsubishi electric DC series. At that time, only three household air conditioners used rotary compressors with fixed frequency (at the same time, more than two household air conditioners were basically piston compressors with low efficiency). At the same time, mitsubishi electric and Mitsubishi Heavy Industries have rotation standards for imported air conditioners in China.
The above picture shows 40 sets of fixed frequency imported by Mitsubishi Heavy Industries of Japan, which may be SRK453HENF. Year: Before 1997, Mitsubishi Heavy Industries imported 3 Japanese fixed frequency cabinets (nearly 4KG R22 was filled in the impression, which was close to the full volume of some 5 domestic fixed frequency R22) Year: before 2000.

Shanghai-made Fujitsu universal red standard Fujitsu plastic shell external machine frequency setter. Year: before 2006.

Hitachi fixed frequency was made in Shanghai, and the air conditioner was around 2000-2003.
Fujitsu set a frequency of 3500+ RMB in that year.
