Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a low-temperature humidifying air conditioner.

[0002]

2. Description of the Related Art A conventional air conditioner has a structure in which a heat exchange coil, a humidifier, and the like are provided in one air passage in a main body casing.

[0003]

In an animal center, a laboratory, or an unmanned computer room, humidification may be required even during cooling. But,
In the air conditioner having the above-described structure, when a water spray humidifier or a steam humidifier is used as a humidifier in order to humidify low-temperature air (cool air) cooled by a heat exchange coil, atomization or atomization is performed. It is difficult for the water to be mixed and added to the air, and the water adheres to the inner surface of the main body casing and the inner surface of the duct to be in a wet state, which may lead to water leakage to the outside. Therefore, when such low-temperature humidification is performed, there is a problem that an eliminator is required and the cost increases. Then, it aims at providing the low temperature humidification air conditioner which solves these problems.

[0004]

To achieve the above object, an air conditioner for low-temperature humidification according to the present invention comprises a cooling air passage, a humidification air passage, a cooling air passage, and a cooling air passage inside a main body casing. A blower for generating an airflow in the humidifying air passage, a cooling coil in the cooling air passage, a heating coil and a humidifier in the humidifying air passage, cooling air in the cooling air passage and the humidifying air passage. The humidified air is mixed.

[0005]

Next, the air conditioner for low-temperature humidification of the present invention will be described in detail. FIG. 1 is a front view, and FIG. 2 is a plan view thereof, showing an embodiment of the present invention. This air conditioner includes an air introduction passage 2, a cooling air passage 3, a humidifying air passage 4, and a cooling air passage 3 inside a flat box-shaped main body casing 1.
And a blower 5 for generating an air flow in the humidification air passage 4.

The air introduction passage 2, the cooling air passage 3 and the humidification air passage 4 are formed by partitioning the inside of the main body casing 1 with an interior plate or the like. In FIG. 1, a white arrow indicates an airflow direction, and an upstream portion of the air introduction path 2 in the airflow direction is a suction port 6.
The downstream portion of the air introduction passage 2 in the airflow direction is connected to the upstream portion of the cooling air passage 3 and the humidification air passage 4 in the airflow direction. The downstream portion of the cooling air passage 3 in the airflow direction is a cold air outlet 7.
The downstream part of the humidification air passage 4 in the airflow direction is connected to a humid air outlet 8.

The air introduction passage 2 is provided with a filter 9 and a blower 5 for pushing air into the cooling air passage 3 and the humidification air passage 4 to return air from the space to be conditioned or outside air. The air is introduced into the air introduction passage 2 through the duct 14 by the blower 5, and is divided and sent to the cooling air passage 3 and the humidification air passage 4. As described above, if the air introduction passage 2 is bifurcated and connected to the cooling air passage 3 and the humidification air passage 4 so that the blower 5 is of a push-in type, only one air introduction passage 2 and one blower 5 are required and the size is reduced. Can achieve

A cooling coil 10 and a drain pan 11 are provided in the cooling air passage 3, and the diverted air from the air introduction passage 2 is cooled by the cooling coil 10. A heating coil 12 and a humidifier 13 are provided in the humidifying air passage 4.
Is provided upstream of the humidifier 13 in the airflow direction. In the humidification air passage 4, the diverted air from the air introduction passage 2 is heated by the heating coil 12 and then humidified by the humidifier 13.
The humidified air in the humidified air passage 4 and the cooled air in the cooling air passage 3 are sent to the air-conditioned space via the ducts 15 and 16 to be mixed (mixed). Thereby, the air-conditioned space is air-conditioned to a desired humidity at a low temperature.

The present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the gist of the present invention. Although not shown, humidified air in the humidified air passage 4 and cooled air in the cooling air passage 3 are supplied to the inside or outside of the main casing 1 (for example, a duct, a mixing box, an air supply port of a space to be air-conditioned, or the inside of the air-conditioned space). ) Can be freely mixed. In addition, the air is diverted on the way,
Instead of sending the air to the humidification air passage 4, the air may be separately sent from the beginning and sent to the cooling air passage 3 and the humidification air passage 4 . Humidification unit 13 is also free to that of water spray or steam type other various.

[0010]

According to the first aspect of the present invention, the air is divided into the humidification air passage 4 and the cooling air passage 3, and the humidification air passage 4 performs humidification, and the cooling air passage 3 performs cooling, respectively. Since the humidified air and the cooling air are mixed, even if a water spray type humidifier or a steam type humidifier is used for the humidifier 13, the sprayed or atomized water is added to the air, and the inner surface of the main body casing 1 and the duct are dried. The inner surface does not get wet, eliminating the need for an eliminator and reducing costs. The relative humidity of the air is lowered by the heating coil 12 to improve the humidification efficiency (effective humidification amount / steam generation amount or water spray amount), and the evaporation absorption distance (the amount of sprayed or atomized water is absorbed by the flowing air). Distance). Therefore, the internal humidifier and the external humidifier can be reliably prevented from being wetted by water spray type humidifier or steam type humidifier, and the humidifying air passage can be shortened, and the air conditioner can be downsized.
