PRESS RELEASE

January 16,2014
Fujitsu General Limited
(NO.13-N05-28)

Realizing highest level energy-saving performance and industry's smallest class(*1) outdoor unit

New release of multi air conditioning system for housing “AIRSTAGE®” J-IIS series for China

(3 outdoor unit models/33 indoor unit models)

Our company will release inverter-type multi air conditioning system “AIRSTAGE®” J-IIS series (11.2/14.0/15.1kW) realizing China Energy Label Class 1(*2) energy-saving performance and industry's smallest class(*1) outdoor unit for the housing air conditioner market in China from January, 2014.

In the urban area of China, high-rise condominiums are main housing for medium and wealthy households, and in the air conditioner market, the demand for multi air conditioners in the 11kW – 15kW (6 rooms – 8 rooms) class controlling the temperature of individual rooms with one outdoor unit is growing by more than 20% per year in the past 3 years. Also, as the energy-saving regulations are becoming strict, high energy-saving performance is required for multi air conditioners for housing.

On the other hand, in case of condominiums, as the space to install outdoor unit is limited, the downsizing of outdoor unit is demanded.

To cope with such needs, in the new series of outdoor units, China Energy Label Class 1(*2) energy-saving performance and the industry's smallest class(*1) outdoor unit downsizing by 25%(*3) compared with conventional models were realized by adopting energy-saving devices such as “Small-size high-efficiency compressor” and “High-efficiency heat exchanger” and the optimization of structure such as changing conventional twin fan designing to single fan designing.

Also, duct-type indoor unit enhancing low-noise operation by reviewing the structure and new wired remote controller with good operationability were newly added to the lineup.

By introducing the “AIRSTAGE®” J-IIS series to the market, we will aim to further expand the air conditioner business in China.

    2. Enabling simple installation even in limited space or veranda by adopting small-size single fan.
  2. Low-profile duct type indoor unit adopting 6-step air volume switching function
    1. Realizing quiet operation of 20dB at low-noise mode by newly adopting 6-step volume switching function.
    2. Low-profile designing (198mm in height) easy to install even in narrow space under the roof.
    3. Air flowing auto louver to change wind direction automatically available on option.
  3. New wired remote controller enhancing visibility and operationability

1.Realizing China Energy Label Class 1(*2) (highest rank) energy-saving performance and industry's smallest class(*1) outdoor unit

China Energy Label Class 1(*2) energy-saving performance and industry's smallest class(*1) outdoor unit were realized by adopting energy-saving devices such as “Small-size high-efficiency compressor”, “High-efficiency heat exchanger” and “V-PAM inverter” and reviewing the structure of outdoor unit including air blowing structure.

i) Energy-saving designing adopting small-size high-efficiency compressor, high-efficiency heat exchanger and V-PAM inverter.

Both high-efficiency operation in actual capacity range and high output operation up to 15kW were realized by adopting our own small-size high efficient DC twin rotary compressor and high-efficiency heat exchanger with high density using Ø7mm copper pipe and by our own V-PAM technology.

Energy Labeling Class 1

ii) Enabling simple installation even in limited space or veranda by adopting small-size single fan

Installation became possible even in limited space or veranda by downsizing outdoor unit using single fan instead of conventional twin fans.

Also, the height of outdoor unit was designed to be less than 1m, lower than the fence of veranda of condominium, not to spoil the sight.

Reducing height by 25%, Reducing volume by 25%, Reducing weight by 26%.

2.Low-profile duct type indoor unit adopting 6-step air volume switching function

i) Realizing quiet operation of 20dB at low-noise mode by newly adopting 6-step volume switching function

Quiet operation of 20dB at low-noise mode was realized by reviewing the structure of air blowing opening and air intake opening and reducing air blowing resistance.
Also, the 6-step switching of air volume was made possible by controlling fan rotation minutely.

ii) Low-profile designing (198mm in height) easy to install even in narrow space under the roof

The low-profile duct-type indoor unit can be installed even in the narrow space under the roof as it can be mounted in the hanging ceiling.


iii) Air flowing auto louver to change wind direction automatically available on option

In the conventional louver, the wind direction was changed manually, but in the auto louver developed newly, as the wind direction is changed automatically according to the contents of operation, comfort is enhanced.
Also, when stopping, as the air blowing opening is closed, indoor unit looks simple.
