• FIG. 25 is a cross-sectional view of the air conditioner 1001 shown in FIG. 19, taken along line C-C' of FIG. 19, when the air conditioner 1001 operates in a third mode.
• FIG. 26 is a cross-sectional view of the air conditioner 1001 shown in FIG. 19, taken along line D-D' of FIG. 19, when the air conditioner 1001 operates in the third mode.
• the air conditioner 1001 may be driven in a first mode for discharging heat-exchanged air only through the first discharge port 1017. Since the discharge panel 1040 is disposed on the first discharge port 1017, air-conditioning may be slowly performed in indoor space. That is, when air is discharged to the outside of the housing 1010 through the first discharge port 1017, wind speed of the air may be reduced when the air passes through the plurality of discharge holes so that the air can be discharged at low speed. According to the configuration, the air conditioner 1001 may cool or heat the indoor space at appropriate wind speed at which a user can feel pleasant.
• outside air of the housing 1010 may enter the inside of the housing 1010 through the first inlet port 1012.
• the air entered the inside of the housing 1010 may pass through the heat exchanger 1030 via the first blow unit 1021 to exchange heat.
• the heat-exchanged air passed through the heat exchanger 1030 may pass through the discharge panel 1040, and thereby be discharged at low speed to the outside of the housing 1010 through the first discharge port 1017. That is, heat-exchanged air discharged through the first flow path S1a may be discharged at wind speed at which a user can feel pleasant.
• the second blow unit 1026 may be not driven, and accordingly, no air may be discharged through the second discharge port 1013.
• the air conditioner 1001 may be driven in a second mode for discharging air not heat-exchanged only through the second discharge port 1013. Since no heat exchanger is disposed on the second flow path S2a, the air conditioner 1001 may circulate indoor air.
• outside air of the housing 1010 may enter the inside of the housing 1010 through the second inlet port 1015.
• the air entered the inside of the housing 1010 may pass through the second blow unit 1026, and then move to space of the second flow path S2a, formed to both sides of the first flow path S1a. Then, the air may move upward on the second flow path S2a, and then be discharged to the outside of the housing 1010 through the second discharge port 1013.
• the first blow unit 1021 may be not driven, and accordingly, no air may be discharged through the first discharge port 1017. That is, in the second mode, the air conditioner 1001 may blow air not heat-exchanged so as to perform a function of circulating indoor air or to provide a strong wind to a user.
• the air conditioner 1001 may be driven in a third mode for discharging heat-exchanged air through the first discharge port 1017 and the second discharge port 1013.
• the air conditioner 1001 may discharge cool air farther in the third mode than in the first mode.
• cool air discharged through the first discharge port 1017 may be mixed with cool air discharged through the second discharge port 1013. Also, since air discharged through the second discharge port 1013 is discharged at higher speed than air discharged through the first discharge port 1017, the air discharged through the second discharge port 1013 may move cool air discharged through the first discharge port 1017 farther.
• the air conditioner 1001 can provide the user with pleasant cool air mixed with indoor air.
• the air conditioner 1001 may change a driving force of the first blow unit 1021 and/or the second blow unit 1026, thereby providing cool air to different distances. That is, the first blow unit 1021 may adjust air volume and/or wind speed of air to be discharged through the first discharge port 1017, and the second blow unit 1026 may adjust air volume and/or wind speed of air to be discharged through the second discharge port 1013.
• the air conditioner 1001 may move cool air farther.
• the air conditioner 1001 may provide cool air to a relatively short distance.
