Technical Field
[0001] The invention relates to an air conditioning device that prevents the condensation
(sweating) that will occur on the shell surface due to the temperature difference
by keeping the temperature of main body of the device at a level close to the ambient
temperature by bypassing the airflow from the hot side to the cold side or vice versa.
Prior Art
[0002] Ambient temperature can be decreased or increased to a healthy and comfortable level
by using technological devices with the developments in technology. Climatic air beyond
our control such as heating, cooling, humidifying, dehumidifying, filtering, etc.
is possible to keep within the desired values indoors with air-conditioning devices.
[0003] In the traditional air conditioner, basically, there are heat exchanger where heat
transfer processes, the fan where the airflow is provided, and the fan motor components
that give the movement to the fan. The climatization (conditioning) of the ambient
is provided by directing the ambient air towards the inside of the unit through the
fan and performing heat transfer on the exchanger surface. The conditioned air is
sent to the ambient from the exit nozzle of the device and the desired comfort temperature
is obtained.
[0004] Sweating occurs as a result of the condensation of the moisture in the ambient on
the surface of the device through the cold inside section of the air conditioning
device and the hot ambient. Especially in summer, when the air conditioner is operated
under high temperature and high humidity conditions, the cold fluid passing over the
exchanger causes to cool the plate parts of the device. Condensation occurs locally
on the main body plates which are in contact with the external ambient due to ambient
conditions, and the amount of condensation increases as time passes. In the traditional
method, especially the side plate, top plate, and the bottom and top of the heat exchanger
are covered with insulation to prevent heat loss and condensation on the main body.
Prevention of sweating directly depends on the heat permeability coefficient and thickness
of the insulation material. As a result of the sweating tests, the correct material
and thickness are determined, the necessary insulation is provided and sweating is
prevented. Briefly in current applications, condensation formation on the main body
is prevented by using methods of increasing insulation thickness or adding insulation.
However, increasing the insulation thickness or using materials with a higher heat
permeability coefficient significantly increases labor and production costs during
production.
[0005] This situation, especially in summer conditions, revealed the need for a solution
that prevents the main body parts such as the side plate and top plate around the
heat exchanger from falling below the ambient temperature, thus eliminating the formation
of sweating.
[0006] In the
patent No. DE10044433A1, a solution to prevent sweating is disclosed. However, in the solution mentioned
here, the bypass process is mechanically controlled.
[0007] In the
patent No. US4107939A, a solution to prevent sweating is disclosed. However, condensation is prevented
by manipulating the movement of cold water due to the pressure difference of the bypass
opening made here. In other words, a bypass system due to pressure difference is characterized.
[0008] In the
patent No. US2521866A, a solution to prevent sweating is disclosed. However, in the solution mentioned
here, the bypass process is mechanically controlled. By taking fresh air in by using
a movable damper, the condensation on the inner surface is prevented and corrosion
is prevented.
[0009] In the
patent No. US3385350A, a method in which condensation is prevented by controlling the operation of the
fan is mentioned.
[0010] As a result, bypassing the airflow from the hot side to the cold side or vice versa,
the main body temperature of the device is kept at a level close to the ambient temperature.
Thus, the solution of the present invention is needed to prevent condensation (sweating)
that will occur on the shell surface due to the temperature difference.

jacket or to eliminate its use altogether, thus improving or eliminating the costs
arising from the insulation jacket.

Detailed Description of the Invention
[0020] The present invention relates to the air conditioning device (1) which prevents the
condensation (sweating) that will occur on the shell plate surface due to the temperature
difference. The air condition device ensures that the temperature of the main body
(60) of the device is kept at a level close to the ambient temperature by bypassing
the airflow from the hot side to the cold side or vice versa.
[0021] Especially in the summer months, when the air conditioner is operated under high
temperature and high humidity conditions, the cold fluid passing over the exchanger
causes to cool of the plate parts of the device. In air conditioning devices the humidity
in the ambient condenses on the device surface and becomes liquid as the interior
of the device is cold and the ambient is hot. As a result, corrosion occurs on the
main body surface of the device. In the prior art, the problem of condensation was
solved by increasing the thickness of the insulation or using insulation materials
with a high heat permeability coefficient. The problem of condensation can be easily
solved by the bypass channels (12) formed in the heat exchanger side plate (11) and
by the associated bypass router (13) without the need for extra costs with the present
invention.
[0022] Figure 1 shows a top section view of the air conditioning device (1) of the invention.
As shown in the figure, the air conditioning device (1) of the invention comprises;
- a fan (30) through which airflow is provided,
- a fan motor (20) giving the movement of said fan (30),
- a heat exchanger (10) where heat transfer takes place,
- a heat exchanger side sheet (11) associated with the said heat exchanger (10), comprising
at least one bypass channel (12) and a bypass diverter (13) structure associated therewith,
- a separation plate (40) separating the parts where the fan (30) and the heat exchanger
(10) are located,
- the main body (60) part that surrounds the outside of the device so as to include
the fan (30) and the heat exchanger (10) parts,
- the insulation jacket (50) placed on the inner surface of said main body (60).
[0023] With the air conditioning device (1) of the present invention, a part of the ambient
air that is suctioned by the fan (30) and sent onto the heat exchanger (10) is bypassed
via the bypass channel (12) and bypass router (13) structures on the heat exchanger
side plates (11). The ambient air passing through the mentioned bypass channel (12)
is directed through the bypass router (13) structure in order to be close to the plates
forming the outer shell (60) and the sweating surfaces condensed on the main body
plates (60) as a result of the sweating tests. For this, the angle of the bypass router
(13) structure to the bypass channel (12) must be between 0 and 90 degrees. Thus,
considering the summer conditions, via bypassing the airflow from the hot side (ambient)
to the cold side (device interior) towards the main body (60) surface via bypass channel
(12) and bypass router (13) structures in certain regions, the temperature of the
main body (60) of the device is kept at a level close to the ambient temperature,
and condensation is prevented. Therefore, insulation thickness and costs are reduced.
Corrosion (paint corrosion) that will occur on the outer surface due to condensation
is prevented.
[0024] At the preferred embodiment of the present invention shown in Figures 1, 2, and 3,
there are bypass channels (12) on both the left and right sides of the exchanger side
plate (11) to provide bypass towards the left side and the right side of the main
body (60) surface, and the associated bypass router (13) structures. In other embodiments
of the invention, the number of pair including bypass channels (12) on the exchanger
side plate (11) and the associated bypass router (13) structure can be increased according
to requirement. In Figure 3, a close perspective view of the bypass channel (12) configured
on both left and right sides and the associated bypass router (13) structure is shown.
[0025] Besides, in the alternative embodiment of the invention, as the bypass channel (12)
and the associated bypass router (13) structure are achieved by the shearing method
on the exchanger side plate (11) currently used in the prior art, it is not required
to use a separate part.
[0026] A top section view of the air conditioning device including the exchanger side plate
in the prior art is shown in Figure 4. As shown in the figure, there is no bypass
channel (12) on the traditional exchanger side plate. As a result, there is a difference
between the ambient temperature and the main body temperature, and condensation occurs
on the outer surface of the main body. In Figure 5, a front view of the exchanger
side plate in the prior art is shown.

and outer surface of the main body (60).
