[0002]

2. Description of the Related Art A heat exchange unit in a general air conditioner comprising a filter, a fan, and a heat exchanger includes a cooling coil for passing a refrigerant or cold water for cooling, a heating coil for passing steam or hot water for heating, Alternatively, in the case of an all-air type air-conditioning unit using an electric heater or the like, the air from the room and the outside air taken in as fresh air are filtered by a filter, passed through a cooling or heating heat exchanger, and then humidified. When it is needed, it is humidified and blown into the room through a duct by a fan and circulated.

[0003]

In the above-mentioned conventional air-conditioning equipment, dust of a relatively large size such as dust and mist generated in the room or invading from the outside can be filtered, but fine dust can be filtered. It was difficult to remove gaseous substances such as dust and odor.

In summer, when the cooling coil of the cooling heat exchanger is used, dew condensation occurs on the coil surface to become a wet surface, and when the room temperature is adjusted, the coil surface becomes wet or dry. For this reason, fungi such as molds are generated on the coil surface, and the coil surface is corroded over a long period of use to form oxides, which scatter and give off a bad smell, thereby contaminating the indoor air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioner according to the present invention will be described with reference to FIGS.

The air conditioner is formed by a filter c and a fan d provided in a casing b connected to the chamber a, a wet heat exchanger e, and a duct f communicating the casing b with the inside of the chamber a. The machine housing b was provided with an outside air intake g.

The wet heat of the embodiment shown in FIGS. 1 and 2
In the exchanger e, air passes through the inside mounted in the rotating cylinder 2.
And a water tank 3 into which a part of the water-containing material 1 , that is, a substantially lower half part, is immersed.
The water material 1 is rotated at an appropriate speed by a motor 4, and the remaining part is
Minute, that is, the upper half is facing the room air.
The rotation direction of the water-containing material 1 is air current.
Provided in a direction perpendicular to the direction,
On the other hand, the indoor air flows into the water-containing material 1 from the axial direction indicated by the arrow.
I was led. Note that as the water-containing material 1, a porous metal, a sintered metal, a metal fiber, a ceramic fiber, or another binding material or other porous material is used.

Reference numeral 5 denotes a temperature control device.
Water tank 3 is connected by a circulation path, and the temperature-controlled water in water tank 3 is desired.
Keep at the temperature. 6 is a tank for controlling the temperature-controlled water from the temperature control device 5.
Pump 7 provided in the circulation path to be sent to the side returns to the inside of the water tank 3
Shows a filter that strains conditioned water. The temperature control device 5 is
Cold and hot water generators used in general air conditioning and constant temperature circulation devices
Heating and cooling method uses a compressor
Heat pump method, using heater as auxiliary heater
It is also possible.

In the figure, h denotes an auxiliary heater such as an electric heater provided on the secondary side of the heat exchange section e.

In the above configuration, if water adjusted to an appropriate temperature by the temperature controller 5 is sent into the water tank 3 , both sides of the water-containing material 1
When immersed in water tank 3, it is immersed in temperature-controlled water and gets wet.
Touch indoor air in wet condition. Thus air than in the chamber a by driving the fan d of the air conditioning equipment to a water temperature adjusted by the temperature control device 5 by passing along the wet surface of the water-containing material 1 of the wet heat exchange section e through the filter c depending air conditioning within a predetermined temperature blown filled-in chamber a in via a duct f in the chamber a as conditioned air is performed, and the outside air in the filter c from the indoor air and the outdoor air intake g by contact with a wetted surface
The fine dust and odorous gas molecules which cannot be eliminated by the above are removed by the wet water and can be circulated as clean air into the chamber a. When the water flows down along the surface of the water-containing material 1, the fine water may be splashed. Nevertheless, the droplets are negatively charged and can contribute to the generation of negative ions that are good for the body.

The water used for heat exchange does not require a large amount, and may be replaced periodically, for example, once a day. The form of the wet heat exchange unit e is not limited to the above embodiment, and another embodiment will be described next.

The embodiment shown in FIGS . 3 and 4 uses a large number of circles.
Circular body with plate-shaped hydrous material 1 installed side by side with appropriate ventilation gap

Make sure the upper half is facing the room air
Was.

Although the air blown into the room in this apparatus is considered to have considerable humidity, the water supplied to the heat exchange section e is controlled to be below or near the dew point temperature of the passing air during cooling. it makes without humidification of air and evaporated, intended to dehumidification warped to,
If the water temperature is too high during heating, there is a possibility that the humidification will be excessive. Therefore, the water temperature is controlled to a temperature at which an amount of water necessary for humidification in the room evaporates, for example, about 25 ° C. The amount of heat insufficient for the heating load is heated by an auxiliary heater h provided on the secondary side of the heat exchange unit e.
