Midea and Gree, which is the pseudo-inverter air conditioning technology?

This question is difficult to answer. It can only be said that Midea has really mastered the core technology of inverter air conditioners and the "pearl chain" in the industrial chain of inverter air conditioners, that is, the black box with inverter technology, ultra-low Hz operation technology, compressor vector control technology, GA genetic algorithm control technology, and independent design and manufacture of inverter ic chips.
