Description

Window-type air conditioner with condensate temperature reduction function {WINDOW TYPE AIR-CONDITIONER HAVING CONDENSATE TEMPERATURE REDUCTION FUNCTION}

The present invention separates the flow path of low-temperature condensate generated in the evaporator from the flow path of high-temperature condensate that was injected into the condenser and passed through the condenser, and provides a condensate temperature reduction function that increases the cooling efficiency of the condenser by separately injecting low-temperature condensate into the condenser. It is about a window air conditioner.

In general, an air conditioner is equipped with a refrigeration cycle device consisting of a compressor, condenser, heat exchanger, etc., and is a device that maintains a comfortable indoor atmosphere by controlling the cold formed in the evaporator and the warmth generated in the condenser according to the indoor conditions. am.

Air conditioners can be divided into window air conditioners and separate air conditioners depending on the installation method. Window air conditioners are devices that have all refrigeration cycle devices installed in one case and are installed on windows, etc.

On the other hand, since window air conditioners are installed directly on the window frame or window, there is a problem in that condensate generated from the evaporator must be discharged to the outside separately. Accordingly, conventional window-type air conditioners have removed condensate generated from the evaporator by injecting it into the condenser and exchanging heat.

Meanwhile, the condensate generated in the evaporator has a lower temperature than the condensate that is poured into the condenser and undergoes heat exchange while passing through the condenser. However, in conventional window air conditioners, the low-temperature condensate generated in the evaporator and the high-temperature condensate that was injected into the condenser and passed through the condenser were supplied back to the condenser without separating them.

The casing (not shown) forms the exterior of the window air conditioner 10, and has an indoor suction part (not shown) and an indoor discharge part (not shown) formed on one side of the indoor side to communicate with indoor air, and one side of the outdoor side. An outdoor suction part (not shown) and an outdoor discharge part (not shown) may be formed to communicate with outdoor air. However, the shape is not limited thereto, and of course, it is not limited thereto as long as it has a configuration that communicates with the indoor air and outdoor air, respectively.

The evaporator fan 120 may have a cylindrical appearance extending in the first direction (Z direction), which is a height direction, and as the evaporator fan 120 is driven, indoor air is drawn into the indoor suction unit (not shown). After being sucked in and exchanging heat with the evaporator 110, the cooled air can be discharged into the room through the indoor discharge unit (not shown) to cool the room.

The second heat exchange unit 200 includes a condenser 210 and a condenser fan 220, and the condenser fan 220 may have a cylindrical appearance extending in the first direction (Z direction), which is the height direction. there is.

Here, the condenser 210 may have a plurality of fins 211 stacked side by side in the first direction, and a plurality of refrigerant pipes 212 through which the refrigerant flows. ) can be composed of.

The first receiving part 300 is provided at the lower part of the first heat exchange part 100. The evaporator 110 liquefies water vapor in the air as heat is exchanged to generate condensate. That is, as water vapor in the indoor air comes in contact with the outer surface of the evaporator 110 and exchanges heat, condensed water may be generated. At this time, the generated condensate falls into the first receiving part 300 and is received. The first accommodating part 300 has a first communication hole 310h formed through the bottom surface, and the condensed water contained in the first accommodating part 300 flows through the first communicating hole 310h. It moves to the second accommodating part 400 and is received again in the second accommodating part 400.

The second receiving portion 400 is formed at the bottom of the casing (not shown) and includes a condensate receiving portion 410 for receiving condensate generated from the evaporator 110. A drain pump 420 is installed to deliver the condensed water to the top of the condenser 210. The drain pump 420 delivers the condensed water contained in the condensate receiver 410 to the injection unit 500, which will be described later, through the connection hose 510.

The spray unit 500 includes a connection hose 510 connected to the drain pump 420 and a spray nozzle 520 provided on the upper part of the condenser 210. The spray unit 500 can inject condensed water supplied by the drain pump 420 into the condenser 210. Meanwhile, the spray unit 500 is provided with a water tank at the upper end of the condenser 210 instead of the spray nozzle 520 to allow condensed water to flow, or a hole is formed in the connecting hose 510 to allow the condensed water to fall. In addition, if condensed water can be supplied from the top of the condenser 210 to the condenser 210, the configuration of the spray unit 500 is not limited to this and can be applied.

Here, the condensate received in the condensate receiver 410 includes the above-described first condensate and second condensate, and the first condensate is condensate generated in the evaporator 110 and is stored in the first receiver 300. It may refer to condensate moved to the second receiving part 400 and received, and the second condensate is the condensate remaining after spraying from the condensate spraying part 500 to the condenser 210. 400) may refer to condensate received. That is, the first condensate passes through the condenser 210 and generates heat-exchanged second condensate, and the second condensate is received in the second receiving part 400 and pumped by the drain pump 420. It may be supplied to the injection unit 500.

At this time, the temperatures of the first condensate and the second condensate may be different. That is, the first condensate water generated by heat exchange with the evaporator 110 may have a temperature of 14 degrees Celsius to 16 degrees Celsius, and the second condensate water heat exchanged while passing through the condenser 210 may have a temperature of 28 degrees Celsius to 30 degrees Celsius. That is, the temperature of the first condensate may be lower than the temperature of the second condensate.

Hereinafter, the structures of the first accommodating part and the second accommodating part according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4. Figure 3 is a schematic cutaway showing the first accommodating part and the second accommodating part, and Figure 4 is a schematic perspective view of the second accommodating part.

Referring to FIG. 3 , the first accommodating part 300 and the second accommodating part 400 may be connected by a partition wall 50 . The partition wall 50 extends from the bottom surface of the casing (not shown) along a first height direction and can partition the indoor side and the outdoor side. That is, based on the partition wall 50, the first heat exchange unit 100 for heat exchange with indoor air may be placed on the indoor side, and the second heat exchange unit 200 for heat exchange with outdoor air may be placed on the outdoor side. there is.

The first accommodating part 300 is provided with a first support part 310 that supports the evaporator 110, and the evaporator 110 can be seated inside the first support part 310, and the partition wall The first communication hole 310h may be formed on the bottom surface at (50) side. Meanwhile, the first condensate generated when the evaporator 110 comes into contact with indoor air may fall downward along the evaporator 110 and be accommodated in the first support part 310, and the first communication hole 310h. ) can be guided to the side.

The first receiving portion 300 is formed on the partition wall 50 and may further include a guide groove 320 connected to the first communication hole 310h. At this time, the guide groove 320 may extend from the first communication hole 310h along the first direction, and direct the first condensate falling through the first communication hole 310h to the first communication hole 310h. We can guide you in the direction. By this, the guide groove 320 can move the first condensate to the drain pump 420 at the bottom of the first receiving part 300 in the shortest possible time.

The second receiving part 400 is equipped with the drain pump 420 and may further include a drain part 430 in which the first condensate water and the second condensate water are received. It may be partitioned from the second support portion 440 by a partition wall 50 . Here, the second support part 440 is provided at the lower part of the condenser 210, on which the condenser 210 can be seated, and supports the condenser 210.

Meanwhile, the drain part 430 is formed to communicate with the lower end of the condenser 210, and further includes a second communication hole 430h formed to allow the introduction of second condensed water contained in the lower part of the condenser 210. can do. In other words, the second condensed water heat-exchanged while passing through the condenser 210 may be accommodated in the second support part 440 and guided toward the second communication hole 430h, and may be guided toward the second communication hole 430h. It may flow into the interior of the drain part 430 through (430h).

At this time, the drain portion 430 may further include a flow path dividing wall 431, which extends in the height direction from the bottom surface and communicates with the guide groove 320 and the second communication. It is provided between the holes 430h and may include a flow path separation wall 431 formed to separate the first condensate water flow path and the second condensate water flow path, and the guide groove 320 is connected to the second communication channel. It may be located closer to the drain pump 420 than the hole 430h. Accordingly, the first condensate flowing down along the guide groove 320 moves toward the drain pump 420 based on the flow path dividing wall 431, and the second condensate flows through the flow path dividing wall 431. It moves outward based on . Additionally, because the relatively low temperature first condensate water flows into the drain pump 420 first, the first condensate water may be injected into the condenser 210 first.

Meanwhile, the drain part 430 is formed at the lower part of the drain pump 420, and has a drain surface 432 that guides the first condensate and the second condensate to the inlet (not shown) of the drain pump 420. It may further include, and the flow path separation wall 431 may be formed to surround at least a portion of the perimeter of the drain surface 432. Accordingly, the first condensate and the second condensate may move along the flow path dividing wall 431, but the first condensate may flow into the drain surface 432 first, and the second condensate may flow along the flow path dividing wall 431. It may flow around the outside of (431) and into the drain surface (432).

Here, the drain surface 432 may be formed to be surrounded by a downwardly sloping inclined surface in the circumferential direction, whereby the first condensate and the second condensate can easily move toward the inlet (not shown) along the inclined surface. The first condensate and the second condensate flowing into the drain surface 432 may collect within the drain surface 432 and flow into the inlet (not shown) of the drain pump 420.

Figure 5 is a schematic perspective view of a window air conditioner 10 with a condensate temperature reduction function according to an embodiment of the present invention, and shows the flows of the first condensate L1 and the second condensate L2.

As described above, the first condensate L1 is condensate formed on the surface of the evaporator 110 when indoor air comes into contact with the evaporator 110, and is received in the first receiving part 300, It moves to the second receiving part 400 along the communication hole 310h and the guide groove 320. Thereafter, the first condensate L1 moving into the second receiving part 400 flows inward based on the flow path separation wall 431 and moves to the drain surface 432. The first condensate L1 flowing into the drain pump 420 from the drain surface 432 is injected from the upper part of the condenser 210 through the injection unit 500.

The second condensate L2 generated while passing through the condenser 210 flows into the drain part 430 through the second communication hole 440h. At this time, the second condensate L2 flows outward based on the flow path separation wall 431 and moves to the drain surface 432.

Meanwhile, the first condensate (L1) and the second condensate (L2) may be mixed on the drain surface 432, but the flow path separation wall 431 allows the first condensate (L1) and the second condensate The mixing time of (L2) can be delayed, and the amount of the first condensate (L1) can be increased and supplied quickly, so the condensate injected into the condenser 210 is the relatively low temperature first condensate (L1). ) can be maintained close to the temperature.

Therefore, the window-type air conditioner 10 with a temperature reduction function according to an embodiment of the present invention separates the flow paths of the first condensate (L1) and the second condensate (L2) to prevent them from mixing with each other, and the Heat dissipation performance can be maximized by first injecting the first condensate (L1) into the condenser 210. That is, by injecting the low-temperature first condensate L1 with a large temperature difference from the condenser 210, the effects of sensible heat exchange and latent heat exchange can be maximized, and the cooling performance can be improved as heat dissipation performance is maximized. This can result in a reduction in size and power consumption compared to the same performance of a window-type air conditioner to which this structure is applied.

In the above, the present invention has been described focusing on the embodiments, but the present invention is not limited to the above-described embodiments, and may be modified and implemented by those skilled in the art without changing the technical spirit of the present invention as claimed in the claims.
