Dehumidifying and cooling apparatus

A dehumidifying and cooling apparatus comprising:

• a housing having first, second, and third channels formed therein, first air passing through the first channel, second air passing through the second channel, third air passing through the third 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 and the third air;
• first and second coolers disposed in the respective second and third channels so as to respectively cool the second air and the third air having passed through the desiccant rotor;
• and
• a refrigerant circulation circuit comprising 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 first cooler;
• and
• the third air is one of air introduced from an indoor space, a mixture of air introduced from the indoor space and air introduced from an outdoor space, and air introduced from the outdoor space, and the third air is cooled by the second cooler and is then discharged to the indoor space,
• 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.
