DC Inverter Driven Compressor

By using DC motor, the performance is improved about 20~40Hz during the longest running time of the inverter compressor. At this time, the rotor of the compressor motor is divided into two parts to suppress electromagnetic interference (EMI) and achieve low noise.

Rotational Operation to Distribute the Load of Outdoor Units

Equalizing the running time of each outdoor unit leads to a reduction in the load on the compressors. Compressor rotation operation effectively spreads the running time of each compressor and extends unit life.

Indoor Unit Noise Control

Hitachi products, suitable for variable applications, realize the sound reduction of indoor units with various aspects of fan motor, fan blade and air duct placement, and offer customers the quietest air conditioning environment.
