2.1 New IVX Series
Hitachi is pleased to introduce a new product line of IVX Outdoor Units:
IVX Premium IVX Standard
1 Improved the connected capacity ratio of Indoor Units
from 50 % to 120% of Outdoor Unit capacity (depending
on the models).
2 Increased the number of connectable Indoor Units up to
8 units (depending on the models).
3 Compact sizes (3, 8 and10 HP).
4 Compliant with new Eco Design Directive (EuP Lot
10) and Seasonal Efciency design concept in order
to meet the European Directive on seasonal efciency
(Lot 6/21 coming in 2015) (depending on the models)
5 IU individual operation (factory setting).
6 Minimum connectable capacity of IU can be as low as
0.8 HP.
7 Improved energy performance by new compressor and
new cycle design.
8 Compatibility with the piping of current installations
where R22 or R407C are used (see chapter 9.6).

2.1.1 Main new features
Achievements of these new two series:

Energy-Saving
a) High energy-saving is realized by the improvement of intermediate capacity for the new compressors.
b) Heat exchanger features slitless-type ns to improve the heating performance.
c) The electrical power saving reversing valve is adopted.
d) Improvement of Energy-Saving through the new Indoor Unit High Efciency range and new Remote Controller.
