Description

Condenser for Window Air Conditioners

The present invention relates to a condenser of a window type air conditioner, and more particularly, to condensate the condensate generated in the heat exchange process of the evaporator to the top of the condenser of the outdoor space to improve the condensation efficiency and condensate of the window type air conditioner effectively utilizing the condensate It is about.

Conventional window air conditioner is installed in a window or the like as shown in Figure 1 is provided with a main body 1, the front, the rear is exposed to the inside, the outside, the inside of the main body 1 by the diaphragm (2) 10) and the outdoor space (9) and the diaphragm (2) is provided with a motor (3) for transmitting the rotational force in both directions from the center.

In addition, a compressor (4) for compressing the refrigerant at a high temperature and high pressure is installed in the outdoor space (9), and a condenser (5) condensing the refrigerant compressed at high temperature and high pressure in the compressor (4) at the rear of the condenser at room temperature. Is installed.

The condenser 5 has a plurality of coolant tubes 5a through which the coolant flows, and is arranged in a zigzag form, and the heat dissipation fins 5b are provided on the outer circumferential surface of each coolant tube 5a to radiate heat generated from them to the outside.

In addition, a cooling fan 6 is installed on the rotating shaft 3a formed in the motor 3 at the rear of the motor 3 corresponding to the outdoor space 9, and blows wind toward the condenser 5 to condense the condenser 5. Air-cool). In addition, outdoor suction openings (not shown) are formed at both side plates of the outdoor space portion 9, and an outdoor discharge opening 9a is formed at the rear of the condenser 5.

Therefore, when the cooling fan 6 is rotated by the driving of the motor 3, outdoor air is sucked along the outdoor intake port and passed through the condenser 6 at the rear to air-cool it, and the air heated by heat exchange during air cooling is the outdoor discharge port. And is discharged to the outside along 9a.

On the other hand, the evaporator 7 is installed inside the indoor space 10. The evaporator 7 is an expanded refrigerant flows therein through a capillary tube (not shown), and absorbs ambient heat in the process of evaporating the liquid refrigerant in the refrigerant, thus lowering the room temperature.

The circulation fan 8 is installed in the indoor space 10 corresponding to the motor 3. The circulation fan (8) is rotated by the motor (3), which transmits rotational force in both directions, to circulate the indoor air toward the evaporator (7).

That is, the indoor air inlet 10b through which the indoor air is sucked toward the evaporator 7 by the rotation of the circulation fan 8 is installed, and the cold air cooled by heat exchange while passing through the evaporator 7 behind the indoor air inlet 10b is installed. An indoor discharge port 10a discharged to the room is formed.

In the conventional window type air conditioner configured as described above, when the motor 3 is operated, the circulation fan 8 and the cooling fan 6 installed by being fitted to the rotation shaft 3a in both directions thereof rotate simultaneously. In addition, when the refrigerant is compressed to a high temperature and high pressure in the compressor 4 and then circulated toward the condenser 5, the refrigerant is air-cooled by the wind generated by the rotation of the cooling fan 6.

That is, when the cooling fan 6 is rotated, the outdoor air is sucked into the outdoor space 9 through the outdoor suction port 9b and then passes through the rear condenser 5. At this time, while the strong wind passes through the condenser 5, the heat of the condenser 5 is radiated to the outside to cool the wind is discharged to the outside along the outdoor discharge port (9a).

In addition, the refrigerant condensed at low temperature and low pressure in the condenser 5 is expanded while passing through a capillary tube (not shown), and thus the expanded gas liquid mixed refrigerant is circulated toward the evaporator 7 of the indoor space 10 to provide a double liquid state. The refrigerant of evaporates to absorb external heat.

Therefore, when the circulation fan 8 is rotated by the driving of the motor 3, the indoor air is sucked into the indoor space 10 along the indoor suction port 10b and then cooled while passing through the evaporator 7. In addition, the cooled indoor air is discharged again to the room through the indoor discharge port (10a) is to cool the room cool.

This conventional window air conditioner has a problem that can not effectively process the condensate generated in the heat exchange process of the evaporator.

In addition, there is another problem that it is difficult to expect an increase in the condensation efficiency by using only the cooling fan formed in front of the heat to dissipate heat generated in the condenser.

The present invention has been made in view of the above problems, and by condensing the condensate generated in the heat exchange process of the evaporator to the top of the condenser in the outdoor space to improve the condensation efficiency and provides a condenser of the window type air conditioner effectively utilizing the condensate. Has its purpose.

Referring to the operation of the embodiment of the present invention configured as described above in detail.

First, when cooling is started and the motor 25 is operated, the circulation fan 25a and the blowing fan 25b installed in both directions are rotated and the compressor 27 is operated.

Therefore, when the circulation fan 25a is rotated by the driving of the motor 25, the indoor air is sucked into the indoor space 22 along the indoor suction port 22a, cooled by passing through the evaporator 24, and then cooled. The indoor air is cooled cool by the indoor air is discharged into the room through the indoor discharge port (22b) (101).

At this time, the evaporator 24 is a liquid refrigerant circulated therein to evaporate to absorb external heat, and a large amount of condensed water is generated during the heat exchange process (102).

At this time, the condensate is collected by falling into the drip tray 28 directly below the evaporator 24 and flows into the reservoir 29 at the bottom of the condenser 26 through the hose 28a to store a predetermined amount of condensate.

As the predetermined time elapses, condensed water continues to collect in the reservoir 29, and the surface of the water rises. At the same time, the mouth 32 of the sensing means 30 formed therein rises to operate the switch 31 (103). 104).

Water is condensed into the condenser 26 (106).

At this time, as the blower fan 25b in front of the condenser 26 is also rotated together, the air cooling and water cooling functions are performed at the same time, thereby rapidly dissipating high heat generated in the condenser 26, thereby increasing condensation efficiency.

In addition, the condensed water that has passed through the condenser 26 is re-introduced into the reservoir 29 at the lower end thereof and re-supplied to the watering means 50 through the pumping means 40.

Therefore, when the refrigerant is compressed at a high temperature and high pressure in the compressor 27 and then circulated toward the condenser 26, the condenser 26 is formed by the wind generated by the rotation of the blower fan 25b and the condensed water sprayed from the top of the condenser 26. The refrigerant is liquefied to a low temperature and low pressure therein, and the condensed refrigerant expands through a capillary tube (not shown), and then the expanded gas liquid mixed refrigerant is recirculated toward the evaporator 24 of the indoor space 22. Cooling function is repeatedly performed.
