DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor air conditioner comprising a filter, a fan and a heat exchanger.

[0002]

2. Description of the Related Art A heat exchange unit in a general air conditioner including 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 need to be humidified after being filtered by a filter and passed through a cooling or heating heat exchanger. Then, it is humidified and blown out 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 or mist generated in the room or invading from the outside can be filtered with a filter. However, it was difficult to remove gaseous substances such as fine 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.

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 conditioning equipment 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 between the casing b and the compartment a. , Machine housing b
Was provided with an outside air intake g.

The wet heat exchanger e of the embodiment shown in FIG.
In FIG. 2, a large number of plate-like hydrated materials 1 are vertically arranged in parallel with an appropriate ventilation gap 4 between the upper chamber 2 and the lower chamber 3, and the upper edge of each hydrated material 1 is shown in FIG. As shown in (b), it is fitted and supported in a slit 5 provided in the bottom plate of the upper chamber 2, and a small hole 6 is provided in the bottom plate surface on both sides of the slit 5. This shows that both sides are partially held by the groove 7. As the water-containing material 1, a porous metal, a sintered metal, a metal fiber, a ceramic fiber or the like and other porous materials are used.

Reference numeral 8 denotes a temperature control device which communicates with the upper chamber 2 via a pump 9 and also communicates with the lower chamber 3 via a filter 10. The temperature control device 8 generates cold / hot water used in general air conditioning. It is similar to an apparatus or a constant temperature circulating apparatus, and a heating and cooling method is a heat pump method using a compressor, and a heater can be used as an auxiliary heater.

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 control device 8 is sent into the upper chamber 2 of the wet heat exchange section e, the water falls from the small holes 6 to wet both surfaces of the water-containing material 1 and lower the water-containing material 1. The water in the lower chamber 3 accumulates in the chamber 3, is sent to the temperature controller 8 by the pump 9, is temperature-controlled, and circulates in the upper chamber 2. Therefore, by driving the fan d of the air conditioner, the return air from the inside of the chamber a is passed through the filter c along the wet surface of the water-containing material 1 of the wet heat exchanging section e to reach the water temperature adjusted by the temperature control device 8. Accordingly, the air is blown into the room a through the duct f as conditioned air at a predetermined temperature, and air conditioning in the room a is performed. The fine dust and odorous gas molecules that cannot be eliminated can be removed by the wet water and circulated as clean air into the chamber a, and when the water flows down along the surface of the water-containing material 1, the fine water splashes. However, since the droplets are negatively charged, they 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.

In the embodiment of FIG. 3 , a large number of disk-shaped hydrated materials 1 are juxtaposed with a suitable ventilation gap to form a cylindrical body 14.
The half part was immersed in the water tank 12 and rotated by the motor 13 as in the above embodiment. Further, the embodiment of FIG.
A large number of plate-like hydrous materials 1 are erected in parallel with a ventilation gap,
An appropriate number of injection pipes 15 are provided upstream of the temperature control device 8.
The conditioned water from the water is ejected from the injection pipe 15 via the pump 9 to form a wet surface on the standing hydrated material 1, and an eliminator 16 is provided downstream of the hydrated material 1. The operation is different from that of the above embodiment. Never.

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 rather dehumidification that,
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.
