What is claimed is: 1. An indoor unit for an air conditioner, comprising: a heat exchanger for performing heat exchange: a drain pan for draining condensed water generated while the heat exchanger operates; a connection tube formed at one side of the heat exchanger, for guiding flow of, refrigerant
What is claimed is: 1. An indoor unit for an air conditioner, comprising: a heat exchanger for performing heat exchange: a drain pan for draining condensed water generated while the heat exchanger operates; a connection tube formed at one side of the heat exchanger, for guiding flow of, refrigerant, wherein the connection tube has a tube coupling part at each end, for allowing the refrigerant to communicate with either end of the connection tube; and a flow passage guider selectively fixable to either coupling part. 2. The indoor unit according to claim 1, wherein the tube coupling parts are positioned at left and right sides of the heat exchanger. 3. The indoor unit according to claim 1, wherein at least one the tube coupling parts comprise a sealing cap for closing the connection tube. 4. The indoor unit according to claim 1, further comprising a sealing cap fixed by a welding to sealingly close at least one of the tube coupling parts. 5. The indoor unit according to claim 1, wherein at least one of the tube coupling parts have one end protected by a protection cap. 6. The indoor unit according to claim 1, wherein the flow passage guider has one end coupled to one of the tube coupling parts and the other end exposed to an exterior through a cabinet part. 7. An indoor unit for an air conditioner, comprising: a heat exchanger for performing heat exchange; a drain pan for draining condensed water generated while the heat exchanger operates; a connection tube formed at one side of the heat exchanger, for guiding flow of refrigerant, wherein the connection tube has a tube coupling part at each end, for allowing the refrigerant to communicate with either end of the connection tube; a flow passage guider fixable to one of the tube coupling parts; and a front panel provided with a tube hole at a position corresponding to the tube coupling part. 8. The indoor unit according to claim 7, wherein the flow passage guider is selectively fixable to either tube coupling part. 9. The indoor unit according to claim 7, wherein the front panel comprises a first panel of which position is varied such that a drain hole is positioned at a place corresponding to the drain pan. 10. An indoor unit for an air conditioner, comprising: a heat exchanger for performing heat exchange; a blower part for forcibly blowing air; a drain pan for draining condensed water generated while the heat exchanger operates; a connection tube formed at one side of the heat exchanger, for guiding flow of refrigerant, wherein the connection tube has a tube coupling part at each end, for allowing the refrigerant to communicate with either end of the connection tube; and a flow passage guider fixable to either tube coupling part and extendable to an outer side of the indoor unit. 11. The indoor unit according to claim 10, wherein the tube coupling parts are bilaterally symmetric with each other. 12. The indoor unit according to claim 10, wherein the front panel comprises: a first front panel provided with a penetration hole; and a second front panel separated from the first front panel and provided without the penetration hole. 13. An indoor unit for an air conditioner, comprising: a blower part for forcibly blowing air; a heat exchanger for performing heat exchange; a drain pan provided at one side thereof with a drain part so as to drain condensed water generated while the heat exchanger operates to an exterior; a front panel provided with a penetration hole at a position corresponding to the drain part; a connection tube for guiding flow of refrigerant to the heat exchanger, wherein the connection tube has a tube coupling part at each end, for allowing the refrigerant to communicate with either end of the connection tube; and a flow passage guider selectively fixable to either tube coupling part. 14. The indoor unit according to claim 13, wherein the front panel comprises: a first front panel provided with the penetration hole; and a second front panel separated from the first front panel and provided with out the penetration hole. 15. An indoor unit for an air conditioner, comprising: a lower frame provided with a suction inlet through which air is inflowed; a middle frame formed spaced apart upward by a predetermined distance from the lower frame; a heat exchanger for performing heat exchange; a drain pan on which the heat exchanger is fixed, the drain pan being provided at one side thereof with a drain part so as to drain condensed water generated while the heat exchanger operates to an exterior; a front panel provided with a penetration hole at a position corresponding to the drain part; a connection tube for guiding flow of refrigerant to the heat exchanger, wherein the connection tube has a tube coupling part at each end, for allowing the refrigerant to communicate with either end of the connection tube; and a flow passage guider selectively fixable to either tube coupling part. 16. The indoor unit according to claim 15, wherein the drain pan is selectively mounted on the lower frame or the middle frame. 17. The indoor unit according to claim 15, wherein the position of the drain pan is varied depending on an installation state of the indoor unit.
