A stand-type air conditioner including a casing having at least two air discharge openings and an air suction opening, and a blower fan installed therein. Also included are at least two heat exchangers positioned adjacent to the air discharge openings, respectively, in the casing for exchanging heat with air to be discharged through the air discharge openings. Further, at least one of the air discharge openings is located at a lower portion of the casing in the vicinity of the ground for discharging air near the ground. By discharging cold air from an upper side during the cooling operation and hot air from a lower side during the heating operation, the cold air or the hot air can be evenly distributed to the room. Accordingly, uniform cooling/heating can be realized to thereby significantly increase reliability and efficiency of a product.

What is claimed is: 1. A stand-type air conditioner comprising: a casing having at least two air discharge openings and an air suction opening, and a blower fan installed therein; at least two heat exchangers positioned adjacent to the air discharge openings, respectively, in the casing for exchanging heat with air to be discharged through the air discharge openings; a first flow channel control means controlling air flow from the blower fan toward a first heat exchanger of the at least two heat exchangers and installed at a flow channel therebetween; and a second flow channel control means controlling air flow from the blower fan toward a second heat exchanger of the at least two heat exchangers and installed at a flow channel therebetween, wherein at least one of the air discharge openings is located at a lower portion of the casing in the vicinity of the ground for discharging air near the ground. 2. The stand-type air conditioner of claim 1, wherein the air suction opening is formed in the middle of the casing. 3. The stand-type air conditioner of claim 2, wherein the air discharge openings comprise: a first air discharge opening formed at an upper portion of the casing on the basis of the air suction opening; and a second air discharge opening formed at a lower portion of the casing and near the ground. 4. The stand-type air conditioner of claim 3, wherein: the first heat exchanger is positioned adjacent to the first air discharge opening, and the second heat exchanger is positioned adjacent to the second air discharge opening. 5. The stand-type air conditioner of claim 4, wherein the blower fan is installed adjacent to the air suction opening, and sucks air from the outside of the casing and transmits the sucked air to the first heat exchanger and the second heat exchanger. 6. The stand-type air conditioner of claim 5, wherein the blower fan is a turbo fan. 7. The stand-type air conditioner of claim 5, wherein the first and second heat exchangers are inclined at a certain angle to the direction in which air transmitted from the blower fan flows so as to make an air contact surface area larger. 8. The stand-type air conditioner of claim 1, wherein the flow channel control means comprise: guide rails fixedly installed perpendicular to the flow channels; and doors slidingly coupled with the guide rails and controlling the amount of air flow. 9. The stand-type air conditioner of claim 1, wherein, during heating, since the flow channel from the blower fan toward the first heat exchanger is blocked by the first flow channel control means, air heated passing through the second heat exchanger is discharged to the outside of the casing through the second air discharge opening. 10. The stand-type air conditioner of claim 1, wherein, during cooling, since the flow channel from the blower fan toward the second heat exchanger is blocked by the second flow channel control means, air cooled passing through the first heat exchanger is discharged to the outside of the casing through the first air discharge opening. 11. The stand-type air conditioner of claim 1, wherein, during cooling or heating, since both of the first and second flow channel control means are opened, air cooled or heated passing through the first and second heat exchangers is discharged to the outside of the casing through the first and the second discharge openings. 12. The stand-type air conditioner of claim 9, wherein the refrigerant is supplied only to the second heat exchanger. 13. The stand-type air conditioner of claim 10, wherein the refrigerant is supplied only to the first heat exchanger. 14. The stand-type air conditioner of claim 11, wherein the refrigerants are supplied to both of the first and second heat exchangers. 15. A stand-type air conditioner comprising: a casing having at least two air discharge openings and an air suction opening, and a blower fan installed therein; and at least two heat exchangers positioned adjacent to the air discharge openings, respectively, in the casing for exchanging heat with air to be discharged through the air discharge openings; and an opening/closing means for blocking the air suction opening when the air conditioner does not operate, wherein at least one of the air discharge openings is located at a lower portion of the casing in the vicinity of the ground for discharging air near the ground. 16. An air conditioner comprising: a casing having at least first and second air discharge openings and an air suction opening on a front surface thereof; a blower fan installed within the casing; and at least first and second heat exchangers positioned adjacent to the first and second air discharge openings, respectively, in the casing for exchanging heat with air to be discharged through the first and second air discharge openings, wherein the first air discharge opening is located at a lower front portion of the casing in the vicinity of the ground for discharging heated air near the ground, and the second air discharge opening is located at an upper front portion of the casing for discharging cooled air. 17. The air conditioner of claim 16, further comprising: a controller configured to control air flow from the blower fan toward the first and second heat exchangers. 18. The air conditioner of claim 17, wherein the controller closes the air flow from the blower fan to the second heat exchanger during a heating operation such that the heated air is only discharged from the first heat exchanger, and closes the air flow from the blower fan to the first heat exchanger during a cooling operation such that the cooled air is only discharged from the second heat exchanger. 19. The air conditioner of claim 17, wherein the controller comprises: a first flow controller configured to control the air flow from the blower fan toward the first heat exchanger and installed at a flow channel therebetween; and a second flow controller configured to control the air flow from the blower fan toward the second heat exchanger and installed at a flow channel therebetween. 20. The air conditioner of claim 19, wherein the first and second flow controllers are manually controlled, are automatically controlled via remote control or are automatically controlled based on a measured temperature. 21. The air conditioner of claim 17, wherein the controller comprises: guide rails fixedly installed perpendicular to the flow channels; and doors slidingly coupled with the guide rails and controlling the amount of air flow. 22. The air conditioner of claim 16, wherein the air suction opening is formed in the middle of the casing between the first and second air discharge openings and includes an opening/closing mechanism configured to block the air suction opening when the air conditioner is not operating. 23. The air conditioner of claim 16, wherein the at least first and second air discharge openings further include third and fourth air discharge openings located on respective sides of the casing so as to discharge air to a wider range. 24. The air conditioner of claim 16, wherein the first and second heat exchangers are inclined at a certain angle to the direction in which air transmitted from the blower fan flows so as to make an air contact surface area larger.
