a heating unit disposed inside the first channel; a desiccant rotor which is rotatably provided inside the housing; a cooling unit disposed inside the second channel; and a refrigerant circulation unit having a refrigerant circulation circuit including a compressor and a condenser, wherein the condenser is disposed inside the second channel such that the refrigerant circulated therein, can be condensed by the heat exchange with the second air cooled by the cooling unit. ## Claims ### Claim 1 A dehumidifying and cooling apparatus comprising: a housing having first and second channels formed therein, first air passing through the first channel, second air passing through the second channel; a heater disposed in the first channel to heat the first air; a desiccant rotor rotatably installed in the housing such that the desiccant rotor is dried by the first air heated by the heater and absorbs moisture from the second air; a cooler disposed in the second channel to cool the second air having passed through the desiccant rotor; and a refrigerant circulation circuit including a compressor and a condenser, wherein the condenser is disposed in the second channel so that a refrigerant circulating in the condenser is condensed by heat exchange with the second air cooled by the cooler, wherein a portion of the second air cooled by the cooler is discharged to an outdoor space after heat exchange in the condenser, while a remainder of the second air cooled by the cooler is supplied to an indoor space. ### Claim 2 (depends on 1) The dehumidifying and cooling apparatus of claim 1, wherein the first air is air introduced into the first channel from the outdoor space, and the first air passing through the first channel is discharged to the outdoor space. ### Claim 3 (depends on 1) The dehumidifying and cooling apparatus of claim 1, wherein: the second air is air introduced into the second channel from the outdoor space. ### Claim 4 (depends on 1) The dehumidifying and cooling apparatus of claim 1, further comprising: a first blower disposed in the first channel such that the first air forcibly passes through the first channel; and a second blower disposed in the second channel such that the second air forcibly passes through the second channel. ### Claim 5 (depends on 4) The dehumidifying and cooling apparatus of claim 4, wherein each of the first and second blowers is selectively operated or stopped by a controller. ### Claim 6 (depends on 1) The dehumidifying and cooling apparatus of claim 1, wherein: the refrigerant circulation circuit further comprises an evaporator;
