The refrigerating cycle of an air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle cycles through a series of processes consisting of compression-condensation-expansion-evaporation, and can supply conditioned air that exchanges heat with the refrigerant.

The compressor compresses and discharges the refrigerant gas at high temperature and high pressure, and the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase and releases heat to the surroundings through the condensation process.

The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded by the expansion valve and returns the refrigerant gas in the low-temperature and low-pressure phase to the compressor. The evaporator can achieve a freezing effect by heat exchange with the object to be cooled using the latent heat of evaporation of the refrigerant. Through this cycle, the air conditioner can control the temperature of the indoor space.

The outdoor unit of an air conditioner refers to a part composed of a compressor and an outdoor heat exchanger during a cooling cycle. The indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve may be located in either the indoor unit or the outdoor unit.

The heat exchanger 30 may include a tube and a header coupled to the tube. The structure of the heat exchanger 30 as described above makes it possible to reduce the flow rate of air flowing through the first flow path S1 by generating air resistance. That is, since the first blowing unit 21 is disposed on the rear surface of the heat exchanger 30, the flow rate of the air flowing through the first flow path S1 passes through the heat exchanger 30 and is reduced. Through the arrangement of the heat exchanger 30 and the first blowing unit 21, the functions of the plurality of discharge holes 112 formed in the discharge panel 110 can be maximized.

In the case of a conventional air conditioner including two or more flow passages inside the housing 10, separate additional components are disposed inside the housing 10 to form each flow passage. As a result, the space inside the housing 10 increases, resulting in an increase in the volume of the air conditioner, and an increase in configuration, resulting in increased material costs or poor assembly quality. In addition, as the flow path is formed by the additional configuration, a continuous impact is applied to the assembly structure of the additional configuration by the flow of air on the flow channel, resulting in vibration or noise.

However, in the air conditioner according to an embodiment of the present invention, the first flow path S1 and the second flow path S2 are both formed by the intermediate member 70, and thus a plurality of air conditioners are installed inside the housing 10 without additional configuration. Channels S1 and S2 may be formed.

Accordingly, since no additional components are disposed inside the housing 10 of the air conditioner 1 according to an embodiment of the present invention, the volume can be reduced compared to a conventional air conditioner having a plurality of flow paths, and in the flow path Vibration or noise caused by flowing air can be reduced.

4 and 5 are cross-sectional views showing air flow when the air conditioner according to an embodiment of the present invention operates in the first mode, and FIGS. 6 and 7 are the air conditioner according to the embodiment of the present invention in the second mode. 8 and 9 are cross-sectional views showing air flow when the air conditioner according to an embodiment of the present invention operates in the third mode.

With reference to FIGS. 4 to 9 , the operation of the air conditioner will be described.

First, referring to FIGS. 4 and 5 , the air conditioner 1 may be driven in the first mode of discharging heat-exchanged air only through the first outlet 105 . Since the discharge panel 110 is disposed in the first discharge port 105, air conditioning can be performed slowly throughout the room. That is, when the air is discharged to the outside of the housing 10 through the first discharge port 105, the air velocity is reduced while passing through the plurality of discharge holes 112 of the discharge panel 110 so that the air can be discharged at a low speed. . According to this configuration, the user can cool or heat the room at a wind speed that feels comfortable.

Specifically, as the first blowing unit 21 is driven, external air of the housing 10 may be introduced into the housing 10 through the first inlet 12 . The air introduced into the housing 10 passes through the first blower unit 21 and passes through the heat exchanger 30 to be heat-exchanged. Air that has undergone heat exchange while passing through the heat exchanger 30 passes through the discharge panel 110 and may be discharged to the outside of the housing 10 through the first discharge port 105 in a reduced speed state. That is, the heat-exchanged air discharged through the first flow path S1 can be discharged at a wind speed that the user can feel comfortable with.

Since the second blowing unit 26 is not driven in the first mode, air is not discharged through the second outlet 13 .

Referring to FIGS. 6 and 7 , the air conditioner 1 may be driven in a second mode in which air that has not been heat-exchanged is discharged only through the second outlet 13 . Since no heat exchanger is disposed on the second flow passage S2, the air conditioner 1 can circulate indoor air.

In order for the air conditioner 1 to operate in the second mode, the discharge door 100 is moved from the closed position CP to the open position OP where the second discharge port 13 is opened. Since the guide curved portion 13a is provided in front of the second outlet 13, the air discharged through the second outlet 13 can be discharged to the front of the air conditioner 1. The discharge blades 132 are provided on the second passage S2 , so that the air discharged through the second discharge port 13 can be uniformly discharged in the longitudinal direction of the second discharge port 13 .

Specifically, as the second blower unit 26 is driven, outside air of the housing 10 may flow into the inside of the housing 10 through the second inlet 15 . The air introduced into the housing 10 passes through the second blowing unit 26 and then passes through the inlet 130 of the intermediate member 70 that is opened in the vertical direction to both sides of the first flow path S1. It can be introduced into the second flow path (S2) formed in each. After the air moves upward on the second flow path S2 , it may be discharged to the outside of the housing 10 through the second outlet 13 . At this time, the air may be guided toward the front of the air conditioner 1 along the guide curved portion 13a.

Since the first blowing unit 21 is not driven in the second mode, air is not discharged through the first outlet 105 . That is, in the second mode, since the air conditioner 1 blows air that has not been heat-exchanged, it can simply circulate indoor air or provide strong wind to the user.

Referring to FIGS. 8 and 9 , the air conditioner 1 may be driven in a third mode of discharging heat-exchanged air through the first outlet 105 and the second outlet 13 . In order for the air conditioner 1 to operate in the third mode, the discharge door 100 moves from the closed position CP to the open position OP where the second discharge port 13 is opened. When the air conditioner 1 is driven in the third mode than when it is driven in the first mode, it can discharge cold air farther.

Specifically, when the air conditioner 1 is driven in the third mode, the cool air discharged through the first outlet 105 and the cool air discharged through the second outlet 13 may be mixed. In addition, since the air discharged through the second discharge port 13 is discharged at a higher speed than the air discharged through the first discharge port 105, the air discharged through the second discharge port 13 is discharged through the first discharge port 105. Through this, the discharged cold air can be moved farther.

According to this configuration, the air conditioner 1 can provide a user with comfortable cool air in which the cool air and indoor air are mixed.

In addition, the air conditioner 1 may be provided to provide cool air to various distances by changing the driving force of the first blowing unit 21 and/or the second blowing unit 26 . That is, the first blower unit 21 may be configured to adjust the air volume and/or wind speed of the air discharged through the first discharge port 105, and the second blower unit 26 may be configured to control the second discharge port 13 It may be configured to be able to adjust the wind volume and / or wind speed of the air discharged through.

For example, when increasing the driving force of the second blower unit 26 to increase the air volume and/or wind speed of the air discharged from the second outlet 13, the air conditioner 1 moves the cold air farther. can make it On the other hand, when reducing the driving force of the second blowing unit 26 to reduce the air volume and/or air speed of the air discharged from the second outlet 13, the air conditioner 1 can provide cool air relatively close-range. there is.
