Expanding Product Line-up of
AIRSTAGE™ Multi Air Conditioning System
for Buildings for Overseas Market
Addition of Outdoor Units (4 models of 8-horse power)
and Expansion of Indoor Units
|
We have developed new series (4 models of 8-HP outdoor unit and
3 types 14 models of indoor unit) of "AIRSTAGE™"
multi air conditioning system for buildings for overseas market
and will start selling in February.
Expecting the growth of market of multi air conditioning system
for buildings, we developed heat recovery type of 10 horse power
"AIRSTAGE™" multi air conditioning system for buildings
and made a full-scale entry into the market centered on Europe and
Middle East in September, 2001 and are now expanding the business
to Asia and Oceania. On the occasion of entry into the European
market, we have established " VRF Support Center (London)"
with aim to support our customers and sales promotion activity for
expanding and strengthening the business.
Furthermore, in October 2002, we introduced heat pump type and cooling
only type of 10 horse power as new series of "AIRSTAGE™;"
to meet the needs of customers, by which we are now able to offer
a comfortable air conditioning system suitable for every environment
such as airports, universities and other public facilities as well
as buildings and offices.
This time, we intend to considerably strengthen the product line-up
for sales expansion of multi air conditioning system for buildings
by adding new 8 horse power outdoor units and indoor units.
Addition of new 8 horse power outdoor units makes it possible to
offer not only individual installation of 10 horse power units or
8 horse power units but also the combined installation of 10 horse
power and 8 horse power units realizing more flexible selection
of the system according to the required capacity.
In the new outdoor units of 8 horse power, by adopting "3 compressor
system" of our own development which is highly valued in the
10 horse power units and "Power balance control system"
which supplies the capacity requested at the indoor unit side without
loss, the industry's most efficient*1 operation has been
achieved. Furthermore, the "Selectable operation mode "
which enables the selection of "Hi-power mode" in high
temperature environment or "Energy saving mode" when considering
economical operation according to the temperature environment of
the outdoor installation site and the "silent mode function"
which enables low noise operation at night are incorporated.
Thus, the products excelling in economical operation matching the
installation environment and low noise operation have been developed.
In the new indoor units, we strengthened the product line-up in
pursuit of market needs by developing 41 attractive models of 11
types to cope with various installation environments.

| Main features of "AIRSTAGE™"
multi air conditioning system for buildings |
- Adopting "3 compressor system" and " Power balance control
system " of our own development realizing industry's most efficient
operation*1.
- Incorporating "Selectable operation mode" which enables the
selection of "Hi-power mode" and Energy saving mode.
- Incorporating air flow structure realizing low noise operation
and "silent mode function".
- Abundant range of indoor models.
|
| Main feature 1: Adopting "3 compressor system"
and "Power balance control system" of our own development realizing
industry's most efficient operation*1. |
- Adopting "3 compressor system"
New combination of 3 compressors with different capacity assures
smooth and efficient operation for the required capacity at
the indoor unit side. Each compressor is so designed to prevent
the breakdown of whole system by recovery operation even at
the time of failure of one or two compressors.

| "3 compressor
system" |
- Adopting " Power balance control system "
The " Power balance control system " is adopted, which detects
the information of capacity (required refrigerant volume) required
at the indoor unit and certain pressure of refrigerant gas inhaled
into compressor and controls the operation of compressor with
optimum pressure.
By this system, the compressor operates efficiently without
by-passing surplus refrigerant.
In all R407C models, the most efficient operation in the industry*2
of COP*3 3.1 for cooling and COP3.3 for heating
is realized.
(*2 as air conditioner for overseas, as of Feb. 2003, according
to our company's survey)
(*3 COP means energy consumption efficiency [rated capacity
divided by power consumption )
|
| Main feature 2: Incorporating " Selectable
operation mode " which enables the selection of Hi-power mode and
Energy saving mode. |
In the new outdoor units, operating capacity can be switched according
to the environment of the installation site. The range of capacity
can be selected by a selection switch in advance according to the
installation environment of outdoor unit such as always setting
at higher side by user in the high temperature environment or setting
at lower side considering economy. By this " Selectable operation
mode ", the capacity setting can be varied from " Hi-power
mode " to "Energy saving mode" in the range of about
15%, so that wider variety of needs of users can be coped with.

| Main feature 3: Incorporating air flow structure realizing low noise operation and "silent mode function". |
Industry's lowest noise operation*4has been achieved
through the improvement of air inhaling balance by "V shaped heat
exchanger" and the "Dual casing bell-mouth" structure of our own
development and arranging them in the optimum position.
Also in consideration for ambient environment and in order to meet
the requirement for low noise operation at night, the operation
noise of about 6dB lower than standard operation at 8 horse power
operation has been realized by adopting "silent mode function" with
suppressed fan speed.

1) 5.7 - 8.8kW slim type ceiling cassette air conditioner
In the 5.7 - 8.8kW (20,000 - 30,000BTU) ceiling cassette type air
conditioners which have increasing demand as air conditioning equipment
for buildings, the thinnest air conditioner in the industry *5with
height of 23.5 cm has been realized to be installed even in a narrow
space in the ceiling where the conventional model could not be installed.
Furthermore, by "Slender setting " of our own development which
enables the main unit to slide downward, the unit can be installed
in the narrow space of up to 20.0 cm in the ceiling.

2) 5.2 - 8.8kW wall mounted type air conditioner
Compact size and low noise operation (at "Hi" operation: 44dB, our
current model: 47dB) have been accomplished by high efficiency designing
incorporating a lambda-type heat exchanger. Also, by the combination
of variable power diffuser of our own technology and up/down and
right/left automatic double air direction swing function, the "floor
level heating" with vertical air flow in heating operation and the
"horizontal cooling" with horizontal air flow in cooling operation
are realized for comfortable air conditioning.
Furthermore, considerable improvement of installation work, such
as enhancement of connecting pipe work efficiency, drain hose openings
at both right and left, has been realized.

3) 2.15 - 8.8kW ceiling wall type air conditioner
The new form air conditioner of high efficiency adopting top air-intake
system has been developed with re-designing of heat exchanger and
air channel structure. The industry's largest air volume *6
(1,000m3/h in 7kW class and 750m3/h in 4kW class) and low noise
operation (43dB in 7kW class and 34dB in 4kW class) have been realized.
By smooth air channel which can intake the indoor air from top side
efficiently, the "healthy cooling" with horizontal air flow with
little loss of cool air in cooling operation and the "floor level
heating" with vertical air flow enhancing heating effect at floor
level in heating operation have been made possible realizing the
optimum air conditioning, meeting diverse needs of air conditioning.
Also, by lessening the height to 27 cm, about 5 cm less than conventional
large wall mounted type, the space saving installation near the
ceiling was made possible.
