The
AIRSŪSYSTEM, which
was showcased in Global Entrepolis Singapore 2003,
is an air cycle refrigeration system that uses
atmospheric air as a refrigeration medium. Although
air cycle machines have been known for a long time
and are used most typically on aircrafts, the high
costs involved in the technology have prevented its
widespread use in other industries.
However, the
AIRSŪSYSTEM has been developed with the aim of
increasing the reliability and effectiveness of the
air cycle technology with increased
cost-effectiveness. |

 |
CFC & ammonia-free |
|
|
No CO2 emission |
|
|
Safe; Zero Risk of environmental hazards &
contamination of refrigerated goods |
|
|
No extra safety precautions or regulatory measures
needed |
|
|
Replenishment of refrigerant unnecessary as air is
used |
|
|
Defrosting unnecessary in warehouses |
|
|
The
AIRSŪSYSTEM is a
state-of-the-art air cycle refrigeration system
which completely does away with ammonia and CFC,
therefore eliminating the damage to the ozone
layer. As compared to CFC substitutes such as HCFC,
it has zero Global Warming Potential (GWP).
Therefore, with AIRSŪ system, you can be
environmental-friendly without compromising the
power of modern technology!
The
technology utilizes the cleanest and most natural
refrigerant, namely, air, as the cooling agent. Using a
2-stage compressor / heat-radiation and expander, the
resulting air temperature can be reduced to as low as –50°C.
Since the technology uses air as a refrigerant, no
additional costs are required in replenishing, as air is
freely available. Additionally, the
AIRSŪSYSTEM is composed of only a few but highly advanced
components, thus reducing installation time and maintenance
costs. |
|
The
AIRSŪSYSTEM
produces very low temperatures efficiently using a
patented technology. Air is initially sucked in from
the refrigerated room by the booster compressor.
Heat is removed from the air via the heat exchanger
prior to entry into the expander turbine. The
booster compressor raises the pressure and the air
is cooled before entering the second compressor
which increases the pressure and temperature
further. |
 |
|
The heat-exchanger is
then used to lower the temperature accompanied by
increased pressure; having further cooled in the
heat-exchanger; the air then gets expanded in the
turbine to a very low temperature. Lastly,
condensation is removed before the air is injected
into the refrigeration facility.
(See flowchart
above.)
This system has many applications in
various industries, including major applications in
refrigerated warehouses, delivery centers for groceries,
ship containers, shock freezing of foodstuff,
pharmaceuticals production, refrigerated show-cases,
air-conditioning systems, and others. |
