Hitachi Room Air Conditioning Systems
Hitachi - The Company
Hitachi is one of the largest corporations in the world, with in
excess of 300,000 employees worldwide. Hitachi prides itself on
providing high quality, efficient and reliable air conditioning
solutions across the globe. By investing heavily in Research and
Development Hitachi has secured a place at the forefront of the
industry. Hitachi’s Air Conditioning Range is one of the most extensive
available on the market today with unit capacities ranging from 2.0kW
high wall split systems to the Hitachi screw compressor chillers of over
1000kW. With products and equipment suitable for a variety of
applications, from the domestic conservatory to the modern multi-storey
office environment, the versatility of the Hitachi range is second to
none.
Hitachi Room Air Conditioning Range (RAC)
Hitachi offers an extensive range of Room Air Conditioning units
suitable for domestic and light commercial applications, all operating
with R410A refrigerant. The Monozone/Multizone range provides a
comprehensive selection of DC inverter PAM mono and multi split systems,
maintaining full compatibility of indoor unit throughout the range. The
all DC Inverter PAM driven mono split SUMMIT range is available with
cooling and heating capacities from 2.0kW to 8.0kW and includes a
Hitachi DC Scroll, or DC Twin Rotary compressor which results in high
performance and ultimate efficiency. The latest offering in this range
is the Hitachi Summit Framed Flat series; it is equipped with, anti
bacteria air purifying filters the Hitachi scroll compressor and
provides a noise level of just 20dB(A) in sleep mode. The Hitachi range
of Room Air Conditioners feature a vast array of significant features
all designed with the user in mind!
Utopia Range (IVX & Inverter)
In today's market where energy efficiency is the key, the Utopia
Inverter Range offers the perfect solution. The range is available from
5.0 to 30 Kw, for single, twin, triple or quad installation and is
compatible with the full range of indoor unit styles. With utilisation
of ozone friendly R410A refrigerant as well as the combination of
Hitachi's advanced technology, DC inverter compressor and fan motor, PAM
control and optimised heat exchanger design, energy efficiency comes as
standard.
The award winning IVX Range (20 ~ 30 Kw) not only brings market
leading COP’s, but also variable refrigerant flow and independent
control to the Utopia Range. A powerful horizontal discharge twin fan
outdoor unit suitable for single, twin, triple and quad installations,
and uniquely provides individual multi split control. Environmentally
the IVX wins also reducing refrigerant, energy input, noise, space and
manufacturing impact. The Hitachi Utopia Range offers a choice of nine
indoor units (4 way cassette, mini 4 way cassette, 2 way cassette,
in-the-ceiling, ceiling suspended, wall, mini wall and floor mounted
(cased & uncased) the Utopia range is suitable for every application
where quiet, reliable air conditioning is required, with features that
include reduced noise levels and advanced diagnostic remote controls to
make troubleshooting prompt and simple.
Set Free VRF Systems
Variable Refrigerant Flow (VRF) technology was developed to address
global concerns and the more complex operating conditions demanded by
todays marketplace. Through tremendous investment in research and
development, Hitachi is able to offer impressive VRF systems, the Set
Free range, incorporating heat pump and heat recovery versions with one
of the largest capacity ranges available in the industry from 3HP to
42HP inclusive.
The Set Free Mini (FSVNE) is an extension of the 2-pipe heat pump FSN
range offering 3, 4 and 5HP capacities and the added benefits of the DC
Inverter technology, providing greater efficiency, higher COP ratings
and consequently a shorter cost redemption period. The outdoor units for
the Set Free Mini (FSVNE) range are as their name suggest; compact, 33%
smaller than the standard 5HP Set Free outdoor unit and of horizontal
discharge format. Exceptionally low sound levels are achieved through
the combination of DC-driven fan motor, new high stream fan design and
the streamlined fan guard and casing. Indoor units are common throughout
the Hitachi Set Free & Utopia range, allowing a choice of 9 differing
styles, up to 128 of which can be controlled via a CS-Net system
centrally.
AquaFREE
Hitachi’s AquaFREE system is a Heat Pump heating system for winter,
and a refresh cooling system for summer. The system consists of an
Inverter Heat Pump outdoor unit and a hydraulic water module indoor
unit. The heat pump absorbs heat from the outside, and transfers it to
the water circuit by means of the AquaFREE water module. The AquaFREE
system benefits the environment by reducing both energy input and CO2
emissions.
Hitachi CS-Net Web
CS-NET web is a standalone central controller that can control up to
128 indoor units and up to 16 outdoor units connected to the Hitachi
H-Link communication system. Using its Ethernet port, CS-NET Web
connects to
the Local Area Network or Internet (using a DSL router), allowing remote
parameter setting and monitoring. CS-NET web client software is accessed
directly through Internet Explorer and uses a Java application for
remote control and monitoring.
Air and Water Cooled Chiller Range (R407c)
The Hitachi Samurai Range is available in capacity ranges between
108kW and 1068kW and is manufactured and tested at the state of the art
production facility, HAPE, near Barcelona, Spain. Hitachi have
undertaken significant investment in further production capacity at the
factory and have also installed and commissioned a chiller performance
test facility, together with all load generating ancillaries and PC
based measurement, recording and reporting capabilities.
The Samurai air-cooled chiller is available in both Cooling Only and
Heat Pump options, cooling from 100kW to 1030kW and heat pump from 100kW
to 585kW. The Samurai water-cooled chiller is available from 134kW to
700kW and is one of the most efficient water-cooled chillers available
today. A key factor enabling such a compact footprint is the use of
plate heat exchangers for both the condenser and evaporator. Both air
and water-cooled ranges utilise Hitachi’s own highly reliable and
efficient twin screw compressor. When combined with Hitachi’s advance
electronic control system the Samurai chiller is able to provide full
modulation capacity control, therefore allowing the chiller to
accurately match the required cooling load while maintaining the leaving
water temperature to within +/- 0.5 degrees.
