Daikin and Mitsubishi Electric were the first to advocate multi-spring and set industry standards in Japan. However, VRV was registered as a trademark by Daikin, so the others can only be called VRF.

The advantage of domestic products is that they are cheap and support national enterprises.

Daikin is following Japan’s Haier route, with good after-sales service (badly diligent?), global standards for equipment are not uniform, and many domestic models cannot be found abroad, but its concept It really leads the multi-connection industry.

Mitsubishi Electric does not have such good after-sales service, but it rarely breaks down. (Actual proof) Its equipment has unified global standards.

Daikin is a representative of small-capacity multi-head high-pressure chambers. (However, Daikin itself does not produce inverters or other semiconductor equipment)

Mitsubishi Electric is the only representative of large-capacity, low-voltage chambers with few pipelines. (It produces inverters and semiconductors, and has a monopoly in some fields)

Midea has promoted digital multi-link and variable frequency multi-link. The data shows that iplv is really high. This time at the Beijing Refrigeration Exhibition The series on display includes 5.8! !

Gree, iplv is 5.74.

(Why can the domestic IPLV be so high? I don’t understand)

Mitsubishi Heavy Industries attaches great importance to the military industry, and the civilian industry is not very developed. It was once on the verge of bankruptcy.
