Refrigerating ability increased bysupercooling circuit
DC Compressor
By using DC, the performance is improved at around 30 - 40Hz wherethe operation time of the inverter compressor is longest. Also, to suppresselectromagnetic noise interference and achieve low noise, the rotor hasbeen divided into two and the electric pole displaced.
High COP
Performance is greatly improved by
the high-efficiency, high pressure,
inverter driven scroll compressor.
Reliability greatly improved byoptimised bearing
Intake loss and leakage losslargely reduced by asymmetricscroll lap
Heat loss largely reduced by oilreturn structure
Accurate oiling to the compressor
by improved oiling system

Quiet operation, easy installation and space saving design
Versatile mounting
To expand installation and positioning options, HITACHI hasadded a second drain pipe connector, one more than conventionalunits. Refrigeration pipes have also been improved and can now beconnected at the left, right or rear of the unit.
Space saving design Hitachis unique feature
An innovative fan and heat exchanger design led to the creation oftodays ultra-slim ceiling unit. Fully adjustable mounting brackets permitclose fitting to the ceiling to make installation possible in even the smallestarea. Less than 163mm of vertical space are required for installation.
Quiet Operation
The ceiling unit is equipped with a highly efficient, multi-bladecentrifugal fan that generates a powerful yet gentle airflow throughoutthe room. A redesigned aerodynamically tested air panel minimisesoperational sound even at high fan speeds.
