Abstract

The present disclosure provides that the air conditioning system includes 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; and a dehumidification unit connected to the indoor unit, in which the dehumidification unit includes a regeneration channel including a first outdoor air inlet and an outdoor outlet, a dehumidification channel including an indoor air inlet or a second outdoor air inlet and an indoor supply, 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, and the indoor unit is configured such that the air supplied from the indoor supply unit passes through the evaporator and then is supplied to a room.

First claim

What is claimed is:

1. 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.

2. The air conditioning system of claim 1 , wherein the heat exchange unit is configured to exchange heat between the refrigerant between the condenser and the compressor and the air introduced from the first outdoor air inlet.

3. The air conditioning system of claim 1 , wherein the dehumidification channel is connected to an air duct disposed in the room.

4. The air conditioning system of claim 1 , wherein the dehumidification channel includes a valve allowing air flow to only one of the indoor air inlet and the second outdoor air inlet.

5. The air conditioning system of claim 1 , wherein the regeneration channel is connected to the indoor air inlet, and the system comprises a ventilation and dehumidification mode in which indoor air is introduced into the regeneration channel, while outdoor air is introduced into the dehumidification channel, and an indoor dehumidification mode in which the outdoor air is introduced into the regeneration channel and the outdoor air is introduced into the dehumidification channel.

6. The air conditioning system of claim 1 , wherein a valve adjusts connections with the dehumidification channel toward the dehumidification rotor, an indoor air inflow passage connected to the indoor air inlet, an outdoor air inflow passage connected to the second outdoor air inlet, and an outdoor discharge passage connected to an outside, and
when an indoor dehumidification mode is performed, the dehumidification channel and the indoor air inflow passage are connected, and when a ventilation and dehumidification mode is performed, the dehumidification channel and the outdoor air inflow passage are connected.

7. 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 a room,
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 unit 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 regeneration 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, and
the heat exchange unit is configured to exchange heat between the refrigerant between the condenser and the compressor and the air introduced from the first outdoor air inlet.

8. The air conditioning system of claim 7 , wherein the dehumidification channel is connected to the evaporator disposed in the indoor unit.

9. The air conditioning system of claim 7 , wherein the dehumidification rotor is disposed in the outdoor unit,
in the dehumidification channel, the indoor air inlet and the indoor supply are connected through a duct, and
a valve for adjusting only air of either the indoor air inlet or the second outdoor air inlet to flow into the dehumidification rotor is disposed before the dehumidification rotor on the dehumidification channel.

10. The air conditioning system of claim 9 , wherein a plurality of indoor air inlets and indoor supply units are provided in a room,
the duct is provided with a damper for allowing or blocking air flow, and
the air conditioning system further includes a plurality of fans generating an air flow including the dehumidification channel and the regeneration channel; and
a control unit connected to the damper, the compressor, and the plurality of fans.
