[0002]

2. Description of the Related Art Conventionally, an air purifying apparatus has been used for purifying indoor air which is polluted by dust, pollen, odor, harmful gas components, etc. in a house. Conventionally, air purifiers used in homes are generally filter type air purifiers equipped with a dust collection filter that captures dust and an adsorbent / absorbent filter that adsorbs and absorbs odors and gas components such as activated carbon. Met. However, in this product, the purification performance is impaired due to the dust collection filter becoming clogged and the adsorption / adsorbent-containing filter becoming saturated, so that there is a drawback that maintenance that requires cleaning or replacement of the filter is essential. there were.

[0003]

On the other hand, in the inventor of the present invention, instead of the filter type air purifier, an air cleaner for purifying the air by bringing the air into contact with water is housed. A technology adopted as an air purifying device for automobiles has been proposed. When purifying the air inside a house with this air cleaner, in order to purify the air by contact with the wash water, the pollutants collected from the air should be discharged together with the wash water. There is an advantage that maintenance such as cleaning of a filter such as a filter is not required.

By the way, in the air cleaner, the air purified by contact with the cleaning water has a high humidity, so that proper humidity control can be performed when the purified air is returned indoors. It is what is desired. On the other hand, the conventional indoor dehumidifying means in a house mainly uses the dehumidifying function of the cooling device, and it is possible to use this together with the air cleaner, but in this case, in the winter, it is not used indoors. Considering that heating is performed, it is uneconomical to use the dehumidifying function of the cooling device indoors because it causes a large increase in power cost.

Considering the entire residential space, conventionally, the indoor air is purified separately for each room, and an air conditioning system capable of purifying a plurality of rooms in a house at once is desired. It was a thing.

The present invention has been made in view of the above circumstances, and provides an air cleaner having a purifying function for purifying air inside a house and also having a humidity controlling function that saves power costs. Is. Further, the present invention provides a residential air conditioning system capable of purifying a plurality of rooms in a house with one device at a time.

Therefore, contaminants in the air absorbed in the cleaning water are cleaned after use. It suffices to drain the water together with water and remove it from the inside of the washing tower, which eliminates the need for laborious and costly maintenance such as cleaning and replacement of the filter unlike the conventional filter type air cleaner.

Further, the air cleaner has an indoor cooling function in addition to the air cleaning function. That is, the air purified by contact with the washing water is cooled by the latent heat of vaporization of water (in principle, the temperature of the air after washing can be cooled to the dew point temperature of the air before washing). Therefore,
It is possible to reduce the power cost for air conditioning in a house during the summer. Further, in this air cleaning device, the air sucked into the cleaning tower is humidified when it comes into contact with the cleaning water, so that it can be used as a humidifying device indoors.

In winter, it is possible to dehumidify the high humidity air after washing with water by utilizing the coolness of the outside air. That is, after the refrigerant in the outdoor radiating coil provided outdoors is cooled by the coolness of the outside air, the air after contact with the wash water reaches the cooling coil interposed in the ventilation path to the exhaust port. By circulating, the high-humidity air after washing with water comes into contact with this cooling coil to be dehumidified and discharged indoors from the exhaust port. At this time, the power cost required to cool the cooling coil is high. Is saved by utilizing the cold air of the outside air. Therefore, this air purifier is useful for cold climate housing.

In the air cleaner of the present invention, the heat exchanger of the heating device may be provided in the ventilation path between the cooling coil and the exhaust port.

It is preferable to circulate and reuse the accumulated water in the water storage tank as water. That is, water can be saved by circulating the wash water, and the wash water can be kept at a constant temperature. That is,
When this air purifier is operated continuously, the energy balance between the latent heat of vaporization taken from the wash water and the heat transfer from the air to the wash water when the temperature of the wash water reaches a certain temperature when the wash water and air are brought into contact with each other. This is because is in a parallel state.

In this case, a water supply pipe may be provided on the water storage tank from the outside of the washing tower, and the water supply pipe may be provided with a float valve interlocking with the water level of the water storage tank. In this case, the amount of wash water circulating in the wash tower can be made constant, that is, due to the reduction of wash water circulating in the wash tower due to evaporation when contacted with air. When the level of the sewage of the wash water that accumulates in the water tank drops, the float valve operates in tandem with this to automatically supply water from the water supply pipe to the water tank, and keep the water level in the water tank constant. is there. As a result, the amount of wash water can be automatically controlled.

Further, a drain pipe having a water shutoff valve may be provided from the outside of the washing tower into the water storage tank. In this case, the contaminated wash water can be drained by operating the water shutoff valve.

Further, in the washing tower 1, a pumping pipe 7 having a pumping pump 8 is piped from the water storage tank 14 above the perforated plate 5, and the washing water accumulated in the water storage tank 14 through the water pumping pipe 7 is perforated by the perforated plate. It is designed to be reused on the 5th.

In the air cleaner W, a cooling coil 21 is provided in the space above the perforated plate 5 inside the cleaning tower 1. An outdoor radiating coil 22 pipe-connected to the cooling coil 21 is provided outdoors, and a pump 23 is provided in a connecting pipe portion between the cooling coil 21 and the outdoor radiating coil 22 to configure the cooling device 20. The outdoor radiating coil 22 has a cooling fin so that the refrigerant flowing in the outdoor radiating coil 22 is cooled by the cold outside air in winter or the like. An antifreeze liquid is used as the refrigerant, and the pump 23 circulates the antifreeze liquid from the outdoor radiation coil 22 to the cooling coil 21. The cooling coil 21 serves as a dehumidifier.

A heating device is provided above the cooling coil 21 in the space above the perforated plate 5 inside the washing tower 1.
There are 17 heat exchangers. The heating device 17 is composed of a hot coil 18 as a heat exchanger and a boiler 19 provided outside the washing tower 1 and connected to the hot coil 18 by a pipe, so that hot water is circulated from the boiler 19 to the hot coil 18. It has become.

A demister 16 is provided inside the washing tower 1 between the porous plate 5 and the cooling coil 21.

Next, the operation of the air cleaner W will be described. The arrows in FIG. 1 indicate the flow of air during operation of the air cleaner W.

When the air cleaner W is put into operation, the main fan 2 and the outside air adjusting fan 16 operate, and the pumping pump 8 also operates. Due to the operation of the main fan 2, the inside of the washing tower 1 is depressurized, and the indoor air is sucked into the washing tower 1 through the indoor air inlet 3a, and at the same time, the operation of the outside air adjusting fan 16 causes the outside air intake port through the outside air intake duct 15.

It is exhausted from. At this time, the temperature and humidity of the air exhausted from the exhaust port 4 can be freely adjusted by adjusting the outputs of the cooling device 20 and the heating device 17.

In the air cleaner W, the perforated plate 5
Part of the wash water that has come into contact with the air flows down from the through holes of the perforated plate 5 and falls into the water storage tank 8 at the bottom of the washing tower 1. The sewage of this wash water is permeated again as tap water by the pumping pipe 6. It is adapted to be circulated on the plate 5. By circulating the wash water in this manner, the wash water can be kept at a constant temperature. That is, when the cleaning water and the air are brought into contact with each other, the energy balance between the latent heat of vaporization taken from the cleaning water when the temperature of the cleaning water reaches a certain temperature and the heat transfer from the air to the cleaning water becomes parallel. is there. There is also a water saving effect by recycling the wash water.

By the way, when the air cleaner W is continuously operated, the amount of cleaning water circulating in the cleaning tower 1 is reduced due to evaporation or the like. In this case, the float valve 11 provided in the water supply pipe 9 is used as the water tank. It operates according to the water level drop of No. 8 and automatically supplies the depletion amount of the washing water. Further, the cleaning water circulating in the cleaning tower 1 gradually accumulates dirt due to repeated air cleaning. In this case,
By opening the solenoid valve 13 of the drain pipe 12, the dirty cleaning water can be discharged to the outside of the cleaning tower 1 together with the precipitation of the dirt. Therefore, the air cleaner W can be easily maintained by simply discharging the cleaning water.
Furthermore, the solenoid valve 10 provided on the water supply pipe 9 is closed to close the drainage pipe.
