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 four indoor units (quad system) are connected
to the same outdoor unit.
UTOPIA series consists in three different outdoor unit series: IVX, (2/2.5)HP and ES. All of them incorporate the
Hitachiinverter 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 efciency 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 specic systems a not necessary.
2/2.5HP
Series composed by the smallest capacity units, specially designed for installation where a single combination is the most
suitable solution.
IVX
With nominal capacities from 7.1 kW to 30.0 kW (cooling mode), IVX series is the series with the highest efciency inside
UTOPIA range, allowing the installation with up to four different indoor units (quad system). In addition, to reduce as much
as possible the energy consumption and improve the energy efciency, IVX outdoor units include the “individual operation”
mode, performing an individual control over the connected indoor units to create a zone-based control.
ES
ES(Eco&Small) series stands out because of its efciency with outdoor units of small dimensions. The series is composed
by units with nominal capacities from 7.1 kW to 25.0 kW (cooling mode), allowing also the installation of up to four different
indoor units.
IU
One of the main merits of Hitachi units range is the combinability and exibility of its indoor units SYSTEM FREE. This
outstanding 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.
1.1.3 Environment-friendly units
This range of HITACHI outdoor units uses environmentally-friendly
R410A gas refrigerant, and the RoHS and Green Dot regulations
are applied throughout the manufacturing and installation process
to reect HITACHI’s awareness of environmental respect and
commitment.
R410A is totally environmentally-friendly since it does not contain
any substances that damage the ozone layer:
ODP (ozone depleting product) =0.
HITACHI’s UTOPIA series are very efcient and allow signicant
energy savings compared with conventional systems.
This energy efciency means less production of CO2, which causes the greenhouse effect.
