Air conditioning system

An air conditioning system, comprising:

• a compressor, a condenser, an expansion valve, and an evaporator through which a refrigerant circulates;
• an indoor unit in which the evaporator is disposed;
• an outdoor unit in which the condenser is disposed;
• and
• a dehumidification unit connected to the indoor unit,
• wherein the dehumidification unit includes a regeneration channel including a first outdoor air inlet and an outdoor outlet, a dehumidification channel including an indoor supply and at least one of an indoor air inlet and a second outdoor air inlet, a dehumidification rotor disposed between the regeneration channel and the dehumidification channel, and a heat exchange unit disposed between the dehumidification rotor and the first outdoor air inlet in the regeneration channel to heat passing air,
• wherein the indoor unit is configured such that the air supplied from the indoor supply passes through the evaporator and then is supplied to a room,
• wherein the condenser is an evaporative condenser,
• wherein the evaporative condenser includes:
• a condensing module including a fluid passage;
• a water injection module spraying water passing through the condensing module from an upper portion of the condensing module;
• and
• a blowing module disposed on one side of the condensing module to provide air passing through the condensing module,
• wherein, in the condensing module, a plurality of header columns, each including a first header extending in a first direction with a channel formed therein, a second header extending in the first direction with a channel formed therein, and a plurality of connection tubes extending in a second direction between the first header and the second header while connecting the respective channels, are stacked in a third direction,
• wherein the first to third directions are different from each other, and
• wherein the condensing module, the water injection module, and the blowing module are disposed such that the water sprayed by the water injection module and the air provided by the blowing module pass between the connection tubes of the condensing module.
