for supporting the above elements, and a condensate water groove
19
formed on one side of the air guide
8
for discharging the condensate water in the indoor region into the outdoor region.
When the summer air conditioning mode in the control box
11
is selected by the user, the blower
6
and blowing fan
14
are turned by the driving power from the motor
7
.
Hot air from the indoor is drawn in through the indoor inlet
3
due to the turning power of the blower
6
. The drawn in hot air becomes cold air by heat exchange with the indoor heat exchanger
5
. The cold air passing through the air guide
8
is guided to the indoor outlet
4
and the cold air is discharged into the indoor with the up-down and left-right direction changing of louver
9
and louver
10
, thereby maintaining the indoor temperature.
At this time, namely, when the indoor hot air passes through the indoor heat exchanger
5
where it is heat-exchanged with the cold refrigerant conveyed in the indoor heat exchanger
5
, water condensate is generated. The condensate water is then discharged through the condensate water groove
19
formed on one side of the air guide
8
into the outdoor region.
High temperature refrigerant heat-exchanged with the indoor hot air is transferred to the compressor
17
. The refrigerant is compressed in a high temperature and pressure atmosphere and discharged in to the outdoor heat exchanger
16
. In the outdoor heat exchanger
16
, the temperature of the refrigerant is reduced and conveyed into a capillary tube (not illustrated). The inhaled refrigerant is transferred to the indoor heat exchanger
5
at a low temperature and pressure atmosphere. At this time, the indoor hot air passing through the indoor heat exchanger
5
is heat-exchanged with the cold refrigerant being moved through the indoor heat exchanger
5
.
The outdoor air passing through the outdoor heat exchanger
16
is heat-exchanged and thus the temperature of the air becomes high. The high temperature air of the outdoor is discharged into the outdoor through the outdoor outlet
13
by the turning power of the blowing fan
14
.
The condensate water being drained through the condensate water groove
19
is evaporated through the outdoor heat exchanger
16
by heat exchange, using the turning power of the blowing fan
14
.
As explained above, the outdoor air drawn in through the outdoor inlet
13
is guided to the outdoor heat exchanger
16
through the shroud
15
.
Referring to
FIG. 2
, the shroud
15
comprises an orifice
20
through which passes the outdoor air from the outdoor inlet
12
due to the turning power of the blowing fan. The shroud utilizes a plurality of locking holes
25
for inserting a plurality of screws
27
therein, an upper plate
22
hinge-connected to the shroud for preventing the shroud
15
from the heat travelling through the upper side of the shroud
15
by the outdoor heat exchanger
16
. A pair of projections
23
are formed on two upper sides of the upper plate
22
and, a pair of spigots
24
are provided for receiving the projection
23
.
On the outdoor heat exchanger
16
, an end plate
21
is provided for supporting the outdoor heat exchanger
16
and, a plurality of connecting holes
26
are provided for connecting the shroud
15
to the end plate
21
.
In the conventional window type air conditioner, since the outdoor heat exchanger
16
to be connected to the rear side of the shroud
15
is formed linearly, the heat exchanging area by the outdoor heat exchanger
16
is limited and thereby it is difficult to increase the heat exchanging ratio.
Further, when the condensate water being drained according to the condensate water groove
19
is evaporated through the outdoor heat exchanger
16
by the turning power of the blowing fan
14
, many stains on the outer surface of the air conditioner are created by the flowing of the condensate water. In addition, since the quantity of the condensate water to be dispersed to the outdoor heat exchanger
16
is small, the heat exchanging ratio is decreased and thus the efficiency of the apparatus is decreased.
On the other hand, it is hard to combine the outdoor heat exchanger
16
with the shroud
15
because it is difficult to locate correctly the outdoor heat exchanger
16
.
SUMMARY OF THE INVENTION
