Advantages and disadvantages of Hitachi central air conditioning

At present, the central air-conditioning of the refrigerant system is still the best done by Japanese brands. When it comes to Japanese central air-conditioning, one has to say that Hitachi, one of the Japanese air-conditioning BOSS, is a well-known international central air-conditioning brand. Most air conditioners now use scroll compressors as the core of power, and the world’s first scroll machine for air conditioning was manufactured by Hitachi in 1983.

Advantages of air compressor equipped with permanent magnet synchronous motor

1. High efficiency The high efficiency mentioned here does not only mean that the efficiency of the rated power point is higher than that of the ordinary three-phase asynchronous frequency modulation motor, but refers to its average efficiency in the entire speed range. The excitation field of the permanent magnet synchronous motor is provided by the permanent magnet.
