Abstract
In an air conditioning apparatus, mixed ambient gas obtained by mixing carbon dioxide with ambient gas in a mixing unit communicating with outlets and, moreover, adjusting temperature and humidity of the mixed ambient gas is supplied to a plant substantially uniformly through the outlets installed in the vicinity of the plant, which makes transpiration of leaves of the plant uniform, and further allows air conditioning control to be performed only over the vicinity of the plant and carbon gas concentration to be managed on the same.

1-9. (canceled)
An air conditioning apparatus in plant cultivation that supplies air whose temperature, humidity, and carbon dioxide concentration are adjusted only to a vicinity of a plant, the air conditioning apparatus comprising:
- a carbon dioxide generating unit that generates carbon dioxide whose concentration is adjusted;
- an air supply unit that supplies ambient gas or outer air whose temperature and humidity are adjusted;
- a mixing unit coupled to the carbon dioxide generating unit through a first duct, coupled to the air supply unit through a second duct, and configured to mix the carbon dioxide generated from the carbon dioxide generating unit and the ambient gas or the outer air supplied from the air supply unit, to form a mixed ambient gas;
- and
- connection pipes coupled to the mixing unit, and having a plurality of outlets that supply the mixed ambient gas to the vicinity of the plant, wherein
- at least the three or more outlets are included for one hole for plant planting of a plant cultivation apparatus, and the outlets are installed so that angles formed by centers of the adjacent outlets and a center of the hole for plant planting are equiangular or less than substantially 180 degrees.
