1.1.2 Introduction
Hitachi UTOPIA series is an outdoor unit series designed with the goal to cover the requirements of the split and multisplit
systems, for installations where from one indoor unit (single system) to up to 8 indoor units, are connected to the same IVX
outdoor unit (depending on model).
New UTOPIA series consists in two different outdoor unit series: IVX Premium and IVX Standard, which compliant with
the Seasonal Efficiency driven by the EU's Energy Product Directive (Eco Design Directive (EuP Lot 10)) and Seasonal
Efficiency design concept in order to meet the European Directive on seasonal efficiency (Lot 6/21 coming in 2015) (depen-
ding on the model). The Seasonal Energy Efficiency Ratio (SEER) in cooling and the Seasonal Coefficient of Performance
(SCOP) in heating, show an approach values to the real energy consumption.
UTOPIA series incorporate the Hitachi inverter technology, which makes possible to adapt automatically and without the
user operation the capacity of the unit, so the power input, to the real demand of the installation, increasing the system
efficiency to unattainable levels with other technologies. All UTOPIA units are equipped with a heat pump, resulting in an
air conditioning system valid for the whole year, in which the installation of additional and specific systems a not necessary.
IVX Premium
Nominal capacity from 5 kW to 30 kW (cooling mode). Connectable indoor units up to 8 units (depending on model) and
total combination power from 50% up to 120%, outdoor units from 3 to 12HP, or 90% up to 110% for 2 and 2.5 HP outdoor
units.
IVX Standard
Nominal capacity from 7.1 kW to 30 kW (cooling mode). Connectable indoor units up to 4 units (2 units for 3HP model) and
total combination power from 90% up to 115%, outdoor units from 4 to 12HP, or 90% up to 110% for 3HP outdoor units.
Indoor Units
One of the main merits of Hitachi units range is the combinability and flexibility of its indoor units SYSTEM FREE. This outs-
tanding technology makes possible to use the same indoor units with both UTOPIA and SET FREE outdoor units, making
easier the design, installation and control of the air conditioning installations.
