## Abstract

A downsized air conditioning system including a cooling device that cools air introduced into the air conditioning system to condense moisture contained in the air; a heating device that heats the air; and a humidification device that humidifies the air; wherein: in a plan view of the air conditioning system, at least a part of the humidification device is overlapped with at least a part of the cooling device; the heating device includes first and second heating devices, and in a plan view, at least a part of the first heating device and at least a part of the second heating device are respectively overlapped with at least a part of the cooling device; and when seen along an introduction direction of the air into the air conditioning system, at least a part of the humidification device is overlapped with at least a part of the heating device.

## Claims

### Claim 1

An air conditioning system that regulates a temperature and a humidity of air introduced thereinto, comprising:
a cooling unit including a cooling device, the cooling device including at least a compressor, and cooling the air introduced into the air conditioning system so as to condense moisture contained in the air, and an air mixture member disposed on a downstream side of the cooling device;
a heating unit that heats the air, having a first heating device, the first heating device including a heating device that uses at least a portion of heat from a heating medium, a temperature thereof having been increased in the cooling unit, and a second heating device, including an electric heater having a variable heating capacity; and
a humidification unit, including a humidification device having a heater provided in a storage tank and heating water stored in the storage tank, thereby generating steam that humidifies the air;
wherein:
in a plan view of the air conditioning system, at least a part of the humidification device is overlapped with at least a part of the cooling device;
in a plan view, at least a part of the first heating device and at least a part of the second heating device are respectively overlapped with at least another part of the cooling device; and
when seen along an introduction direction of the air into the air conditioning system, at least another part of the first heating device and at least another part of the second heating device are overlapped with at least another part of the humidification device.

### Claim 2 (depends on 1)

The air conditioning system according to claim 1, wherein:
an introduction port of air into the air conditioning system is opened toward one side of a first direction; and
the humidification device is disposed on the one side of the first direction with respect to the heating device.

### Claim 3 (depends on 1)

The air conditioning system according to claim 1, wherein:
the cooling device includes a plurality of heat transfer fins;
the plurality of heat transfer fins extend in a direction that is inclined with respect to a horizontal direction and to a vertical direction; and
air flowing through the cooling device is guided by the plurality of heat transfer fins to move in the direction that is inclined with respect to the horizontal direction and to the vertical direction so as to flow upward from an upstream side toward a downstream side.
