Hitachi High-efficiency Set Free VRF System
New-type Scroll Compressor
Uses a high-pressure scroll-type compressor with improved quality and reliability of compressor mechanism materials.
DC Compressor (24 & 30 HP Units)
By using DC, the performance is improved at around 30-40 Hz where the
operation time of the invertor compressor is longest. Also, to suppress
electromagnetic noise interference and achieved low noise, the rotor
has been divided into two and the electric pole displaced.
High-performance Heat Exchanger
A new high-performance heat exchanger has been developed with improved piping arrangement .
Self-diagnostic System
The self-diagnosis result is shown on a digital display via control
from either a remote control (relating to indoor units) or one of the
outdoor units. This air conditioning system can be checked for operation
even through the printed circuit board in the outdoor unit, allowing
you to carry out inspection work and/or take remedies more quickly and
correctly.
