Description
TECHNICAL FIELD
The present invention relates to an outdoor unit for an air conditioner, and
more particularly to, a built-in type outdoor unit for an air conditioner which
can be installed indoors.
BACKGROUND ART
An air conditioner implying a cooler, a heater or both of them is classified
into
a window type and a split type. In the case of the cooler, a split type air conditioner
includes an indoor unit installed indoors for cooling a room, and an outdoor unit
connected to the indoor unit through refrigerant pipe lines and installed outdoors
to contact air, for performing condensation heat exchange on a refrigerant gas
in a condenser by using external air as a cooling medium, and supplying the condensed
refrigerants to an evaporator of the indoor unit through the refrigerant pipe lines.
The indoor unit is composed of the evaporator for performing cooling heat exchange
for evaporating the refrigerants and absorbing evaporation heat from internal air,
and a ventilating fan for circulating internal air, and the outdoor unit is composed
of a compressor for compressing the refrigerant gas and supplying the compressed
gas to the condenser, the air-cooled condenser for condensing the refrigerant gas
from the compressor, and a cooling fan for forcibly ventilating external air to
the air-cooled condenser to cool and condense the refrigerant gas. The compressor,
the air-cooled condenser and the cooling fan of the outdoor unit are installed
in an outdoor unit casing composing the outer appearance. The conventional hexahedral
outdoor unit casing has an air suction unit for sucking air to the air-cooled condenser
at its three sides, and an air discharge unit for externally discharging air absorbing
condensation heat from the refrigerant gas by the heat exchange in the air-cooled
condenser on its top surface.
However, the conventional outdoor unit for the air conditioner is restricted
in installation spaces due to high density and strict environment regulations of
cities, and increases civil applications due to noise and heat. Especially, a common
residential area such as large-scaled apartment buildings regulates the outdoor
units to be installed in indoor verandas to improve the appearance and prevent noise.
In order to solve the foregoing problems, Japanese Laid-Open Patent Publication
No. 6-101873 suggests an air conditioner mounted building where an indoor unit
of an air conditioner is installed indoors or adjacent to a room intended to be
air-conditioned, and an outdoor unit of the air conditioner is installed outdoors,
wherein an opening is formed on the outer wall or roof, a louver is installed in
the opening, the outdoor unit of the air conditioner is positioned in the louver,
and suction/discharge of the indoor unit is performed through a gap between the
louver plates.
In addition, Japanese Laid-Open Patent Publication No. 3-213928 discloses a wall
built-in type outdoor unit for an air conditioner including an outdoor unit main
body for the air conditioner which is built in the wall and which includes a frame
having the same size and thickness as the wall, a suction hole for heat exchange
air installed on the same surface as the outdoor unit main body, and a discharge
hole for heat exchanged air.
However, the conventional arts relate merely to technologies for inserting
the outdoor unit into a space formed on an outer wall of a building. That is, it
is impossible to install the outdoor unit increased in volume and weight due to
high air conditioning capacity in a built-in type.
The conventional outdoor unit is incorporated in one casing. In order to manage,
examine or repair inside components of the outdoor unit, the whole outer casing
must be separated/disassembled. In the case that the outdoor unit is a built-in
type, a lot of money and time are required to disassemble the outer casing.
Moreover, the conventional outdoor unit has a large size and weight, and
thus is difficult to install, transport and move.

BEST MODE FOR CARRYING OUT THE INVENTION
A built-in type outdoor unit for an air conditioner in accordance with the present
invention will now be described in detail with reference to the accompanying drawings.
FIGS. 1 to 3 are structure views illustrating a built-in type outdoor unit
for an air conditioner in accordance with a preferred embodiment of the present invention.
As illustrated in FIGS. 1 and 2, an external frame
4 is fixedly installed
on a rectangular space inner wall formed on an outer wall
2 of a residential
and/or commercial building, and an internal frame
6 is fixedly installed
at the inside of the external frame
4. The internal and external frames
4 and
6 can be incorporated. An inside area of the internal frame
6 is divided into a suction area
7a and a discharge area
7b.
A plurality of louver blades
8 are installed in each area, so that air can
be sucked or discharged through gaps between the louver blades
8. Hereinafter,
the external frame
4, the internal frame
6 and the louver blades
8 are referred to as a louver frame.
On the other hand, an outdoor unit
10 (partially shown) fixedly installed
at the inside of the outer wall
2 of the building to contact the external
frame
4 and/or internal frame
6 includes an outdoor unit casing.
The outdoor unit casing opens its one side facing the suction area
7a
and the discharge area
7b of the internal frame
6. The
opened side is divided into a suction unit
11a and a discharge unit
11b to correspond to the suction area
7a and the discharge
area
7b of the internal frame
6.
In addition, the louver frame coupled to or separated from the outdoor unit
10
includes a dividing unit
9 for dividing the louver blades of the suction
area
7a from the louver blades
8 of the discharge area
7b.
The dividing unit
9 divides the suction area
7a of the louver
frame from the discharge area
7b at a predetermined interval, to
prevent interferences between external air sucked to the suction area
7a
and heat exchanged air discharged from the discharge area
7b.
Accordingly, the front suction/discharge type outdoor unit
10 rapidly sucks
external air and discharges heat exchanged air. The dividing unit
9 also
prevents air discharged from the louver blades
8 at the lower end of the
discharge area
7b from being re-sucked to the louver blades
8
at the upper end of the suction area
7a, namely isolates air of the
suction area
7a from air of the discharge area
7b,
thereby minimizing contacts of air sucked to the suction area
7a and
heat exchanged air discharged from the discharge area
7b. The dividing
unit
9 has its surface slanted to the discharge area
7b. When
rain or snow flows down by the louver blades
8 of the discharge area
7b,
the slanted surface of the dividing unit
9 externally discharges it.
An air suction/discharge direction can be controlled by adjusting an open angle
of the louver blades
8. In addition, an air suction direction and an air
discharge direction can be distinguished by controlling the louver blades
8
of the suction area
7a and the discharge area
7b to
have different open angles. A manual open device (not shown) operated by force
of the user, and an automatic open device (not shown) for automatically operating
the louver blades
8 according to the operation of an outdoor unit
10,
namely a control command of the outdoor unit
10 performing a series of operations
for cooling/heating can be used as a control means for opening the louver blades
8. The structure and constitution of the manual open device and the automatic
open device for the louver blades are easily understood by ordinary people skilled
in the art to which the present invention pertains. It is also possible to determine
the air suction/discharge direction in consideration of an external environment,
and to open and maintain the louver blades
8 in a predetermined direction.
On the other hand, the outdoor unit
10 fixedly installed at the inside
of the outer wall
2 of the building to contact the external frame
4
and/or internal frame
6 includes an outdoor unit casing composed of components
of FIG. 3. In addition, outdoor unit components of FIG. 3 are installed in the
outdoor unit casing.
In the outdoor unit casing, one side facing the suction area
7a and
the discharge area
7b of the internal frame
6 is opened. The
opened side is divided into a suction unit
11a and a discharge unit
11b to correspond to the suction area
7a and the discharge
area
7b of the internal frame
6. In addition, three side covers
12a,
12b and
12c, a bottom cover
14
and a top cover
16 are closed to form a rectangular parallel piped. A plurality
of leg members
18a,
18b,
18c and
18d
are externally protruded from the bottom cover
14. The leg members
18a,
18b,
18c and
18d are installed on the
bottom of a building, for example a veranda of an apartment building, for supporting
heavy load of the outdoor unit
10. Preferably four leg members
18a,
18b,
18c and
18d are formed in consideration
of the shape of the bottom cover
14. A leg reinforcing member
19
for connecting and reinforcing the leg members
18a,
18b,
18c and
18d is formed below the bottom cover
14
in the horizontal direction. The leg members
18a,
18b,
18c and
18d further include screws (not shown) for
controlling height. Accordingly, when the bottom of the building, for example the
veranda of the apartment building is not flat, they can stably position the outdoor
unit
10. When the two legs
18a and
18b positioned
in the forward direction (toward building outer wall) among the leg members
18a,
18b,
18c and
18d further include wheels
(not shown), it is much easier to transport the heavy load outdoor unit
10.
In the suction unit
11a of the outdoor unit
10, a compressor
20 is installed on a compressor fastening unit
22, and a 'U' shaped
air-cooled condenser
30 is fixedly supported on the side covers
12a
and
12b and the bottom cover
14 by using condenser covers
32a,
32b and
32c and condenser brackets
34a and
34b. In the air-cooled condenser
30,
a plurality of condenser pipe lines are formed in a zigzag shape between a plurality
of condenser fins. The structure and shape of the air-cooled condenser
30
have been publicly known, and thus are not shown in detail. A refrigerant gas compressed
by the compressor
20 is transmitted through the pipe lines of the condenser
30, removed its condensation heat by externally-supplied air, and condensed.
In this case, the condenser covers
32a,
32b and
32c
and the condenser brackets
34a and
34b form a wind
path so as to prevent external air from being supplied to the discharge unit
11b
not via the condenser
30. As a result, external air sucked through the
gaps between the louver blades
8 of the suction area
7a passes
through the 'U' shaped condenser
30 along the wind path of the condenser
covers
32a,
32b and
32c and the condenser
brackets
34a and
34b, and exchanges heat with the refrigerant
gas flowing through the condenser pipe lines.
In the discharge unit
11b of the outdoor unit
10, a cooling
fan
40 for supplying external air to the air-cooled condenser
30
through the suction area
7a and discharging heat exchanged air through
the discharge area
7b is fixedly installed on the side covers
12a,
12b and
12c and the top cover
16 by a cooling
fan supporting member
42 and a cooling fan bracket
44. A sirocco
fan is illustrated as one example of the cooling fan
40. Reference numeral
46 denotes a fan front installed in front of the cooling fan
40.
A control box
50 for controlling the operation of the outdoor unit
10
is installed at the inside of the side cover
12c composing the rear
surface among the side covers, and refrigerant pipe lines which the refrigerant
gas evaporated in the indoor unit is sucked through, and a valve assembly
52,
a path of the refrigerant pipe lines which the refrigerants condensed in the outdoor
unit
10 are discharged through are installed below the control box
50.
A mesh shaped front grill
60 is additionally installed on the front surface
of the outdoor unit
10, namely one opened side facing the suction area
7a
and the discharge area
7b of the internal frame
6 to prevent
invasion of animals (for example, rats).
FIG. 4 is an exemplary view illustrating installation and assembly of the valve
assembly of the outdoor unit of FIG. 1. As shown in FIG. 4, the control box
50
and the valve assembly
52 having openings
80 which pipes
70
and
72 of a service valve pass through are installed on the side cover
12c.
The pipes
70 and
72 of the service valve are paths of the refrigerant
pipe lines which the refrigerant gas evaporated in the indoor unit is sucked through
and the refrigerant pipe lines which the refrigerants condensed in the outdoor
unit are discharged through. A diameter of the openings
80 is greater than
that of the pipes
70 and
72, and gaps
90 are formed between
the openings
80 and the pipes
70 and
72, so that external
air can be sucked into the outdoor unit thorough the gaps
90. In addition,
a sealing member (not shown) for preventing external air from being sucked through
the gaps
90 can be used.
In the case that the indoor unit performs a heating operation, air sucked through
the gaps
90 near the pipes
70 and
72 is hot air. Therefore,
the gaps
90 are sealed up by using the sealing member, and the control box
50 and/or the air-cooled condenser
30 are/is cooled by using cool
air passing through the air-cooled condenser
30.
When the indoor unit performs a cooling operation, air sucked through the gaps
90 near the pipes
70 and
72 is cooler than air passing through
the air-cooled condenser
30. Accordingly, the sealing member is removed
from the gaps
90, and the control box
50 and/or the air-cooled condenser
30 are/is cooled by using air sucked through the gaps
90.
FIG. 5 is a perspective view illustrating an outdoor unit casing in accordance
with a second embodiment of the present invention. Referring to FIG. 5, the outdoor
unit
100 includes a separable outdoor unit suction casing
11c
and a separable outdoor unit discharge casing
11d. Here, the
outdoor unit suction casing
11c and the outdoor unit discharge casing
11d have their one surface opened to correspond to the suction area
7a and the discharge area
7b of the louver frame, and
their another surface connected so that heat exchanged air can move through. That
is, the outdoor unit suction casing
11c corresponds to the suction
unit
11a of the outdoor unit
10, and the outdoor unit discharge
casing
11d corresponds to the discharge unit
11b of
the outdoor unit
10. The outdoor unit suction casing
11c and
the outdoor unit discharge casing
11d can be coupled to or separated
from each other by using a special fastening device (bolts and nuts, guide holes
and hooks, etc.) (not shown).
The outdoor unit
100 which can be coupled/separated reduces its whole
weight and size to be easily transported and moved. The outdoor unit
100
can also be easily installed by firstly installing the outdoor unit suction casing
11c, and then installing the outdoor unit discharge casing
11d.
For management and repair, the outdoor unit
100 is partially separated and
disassembled so that its inside components can be examined. That is, the outdoor
unit
100 has a simplified structure in time and cost.
FIG. 6 is a plan view illustrating mounted constitution of the louver frame
and the outdoor unit of FIG. 1. As illustrated in FIG. 6, a width of the outdoor
unit
10 is smaller than that of an internal space of the external frame
4 fixedly installed at the inside of the outer wall, and thus the outdoor
unit
10 is fixed to the external frame
4 and the side covers
12a
and
12b by using a special fastening member, for example 'L'
shaped brackets
62. In this case, the outdoor unit
10 is not fixed
to the concrete outer wall
2, and thus is easily fixedly installed. In addition,
a gap exists between the concrete outer wall
2 and the outdoor unit
10
as large as the external frame
4, and thus the outdoor unit
10 is
easily fixedly installed.
Moreover, a plate shape sealing member
64 is inserted between the
internal frame
6 and the outdoor unit casing, so that external air sucked
through the suction area
7a can pass through the suction unit
11a
without being leaked to other spaces (for example, discharge unit
11b),
and that air discharged from the discharge unit
11b can be externally
discharged through the discharge area
7b without being leaked to
other spaces (for example, suction unit
11a). A plate shape vibration
isolating member
66 is inserted into the front surface of the outdoor unit
casing so that the outdoor unit
10 can absorb vibration of the cooling fan
(not shown).
A fastening member, a plate shape sealing member and a plate shape vibration
isolating
member can also be applied to the separable outdoor unit
100 like the outdoor
unit
10.
Although the preferred embodiments of the present invention have been described,
it is understood that the present invention should not be limited to these preferred
embodiments but various changes and modifications can be made by one skilled in
the art within the spirit and scope of the present invention as hereinafter claimed.
