System for ventilation, dehumidification, and cooling

A system for ventilation, dehumidification, and cooling, the system comprising:

• an outdoor unit dehumidifying and cooling introduced outside air;
• and
• an indoor unit connected to the outdoor unit to perform ventilation,
• wherein the outdoor unit includes:
• a first flow path connecting an outside and an indoor space and on which an evaporative cooler is disposed;
• a second flow path connecting the outside or the indoor space and a dehumidification rotor and on which a heating unit is disposed;
• a third flow path connecting the evaporative cooler and the outside;
• a fourth flow path connecting an evaporative condenser and the outside;
• the dehumidification rotor rotating in a first region provided on the first flow path and a second region provided on the second flow path, dehumidifying the first region, and regenerated in the second region;
• the evaporative cooler including a dry channel provided on the first flow path and a wet channel provided on the third flow path and to which water is sprayed by a first water injection module, and cooling air passing through the dehumidification rotor;
• the evaporative condenser through which the air passing through the dry channel of the evaporative cooler passes on the fourth flow path and into which the water is sprayed by a second water injection module;
• a ventilation damper provided on the first flow path and controlling introduction of the air passing through the evaporative cooler into the indoor space;
• the heating unit provided on the second flow path on an upstream side of the second region and heating the air moving to the second region;
• and
• a control module operating or stopping at least one of the dehumidification rotor, the evaporative cooler, the evaporative condenser, the ventilation damper, or the heating unit.
