DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides a dust-removal air conditioning method and device for removing dust and bacteria from air discharged from a room and controlling the temperature and humidity to a predetermined temperature and relative humidity. In particular, a large amount of fine water droplets are generated in a heat exchange cyclone to efficiently exchange heat and air condition the room without getting it wet.
The present invention relates to a simple and compact air-conditioning method for removing dust and germs, which efficiently utilizes a heat pump to efficiently perform cooling and heating treatments at the same time, and an apparatus therefor. Therefore, the present invention provides hospitals,
It is especially useful in places where ultra-clean environments are required, such as laboratories and LSI factories, and as indoor clean air conditioning systems.

[Conventional technology]

Generally, in a heat exchanger, when water is simply sprayed and air is brought into contact with the evaporation tube of the refrigerant #i ring to bring the air to a low temperature and saturated relative humidity, dust and fungi in the air can be removed. In addition, the water freezes in the evaporator tube, preventing efficient heat exchange between the air and the refrigerant. A compact system did not exist.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks by injecting water against the evaporation pipe of the refrigerant circulation and/or the inner wall of the cyclone, and forming microscopic water droplets much smaller than conventional water droplets by the impact thereof. , the important point is to utilize this.

By using minute water droplets, not only can heat exchange with the air be efficiently carried out, but also extremely minute foreign substances such as dust and fungi contained in the air can be efficiently removed. It is also an object of the invention to provide a system in which the ultra-clean heat-exchanged air does not become wet and overhumidified despite containing water droplets.

Also, such exclusion III! l By installing a heat pump as a cooling and heating means for the air conditioning system, not only can it be operated at low cost, but also an internal cyclone for heat exchange is installed in order to make the entire system compact, and the cyclone is installed externally. It is also an object of the present invention to provide an energy-saving and compact system by arranging a surrounding annular heated and humidified chamber and further arranging a fan between the two to promote air flow.

In addition, by rapidly injecting water and applying shock, the evaporator tube should not be given an opportunity for water to freeze, and even if water freezes in the evaporator tube, the ice should be removed. The evaporator tube is always in direct contact with the air to prevent the evaporator tube from freezing, allowing heat exchange to take place between the refrigerant and the air, bringing the air to a low temperature and saturated relative humidity. It is also an object of the invention to develop a new system for raising air to a predetermined temperature and obtaining a predetermined relative humidity.

[Example - Configuration]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dust removal canopy air conditioning system 1 for carrying out the dust removal ceramic air conditioning method of the present invention will be described below with reference to the drawings.

The positional relationship between the evaporation tube 50 and the injection nozzle 13 is such that the water from the injection nozzle 13 is sprayed against the evaporation tube 30 and/or the inner wall of the cylindrical portion to form fine water droplets. .

Furthermore, a 7-ring 6 is arranged above the first outlet pipe 11 to suck the air inside the outlet f11 and promote the flow of the air. A water tank 5 and a pump 17 are provided at the lower end of the conical portion 63 of the Cycloc 30. Therefore, the cold water is circulated in the direction of arrow B, that is, in the order of pump 17 → water supply pipe 14 → injection pipe 12 → cyclone 30 cylindrical part 31 → its conical part 36 → water tank 5 → filtration device 16 → Ponzo 17. The refrigerant, especially the high temperature refrigerant (approximately 1°C to -5°C), is supplied in the direction of arrow C, that is, from the refrigerator (not shown) to the cooling supply pipe 9.

In the drawing, a reservoir annular air passage 15 for discharging the air discharged from the outlet pipe 11 of the heat exchanger cyclone 3 downwards is arranged between the chamber 4 and the cyclone 3.

Particularly when the indoor temperature is high, such as in the summer, when the superhumidified air discharged from the outlet pipe 11 is treated in the heating and humidity control chamber 4, there is no need to strongly heat it, and it is sufficient to simply dehumidify it. Therefore, at least a portion of the heating supply pipe 19 is taken outside and cooled to suppress the rise in temperature of the air discharged into the room.

This prevents the rise in room temperature and increases air conditioning efficiency. In order to further improve the cooling efficiency, a 77-inch S may be provided.

[Example - Effect]

Next, the operation of the dust removal and bacteria air conditioner 1 will be explained.

Air in the chamber enters through the inlet pipe 8 and is blown into the heat exchange cyclone 3 through the inlet 32. The blown air is made to have a saturated relative humidity by jetting cold water, and is cooled by directly contacting the evaporation tube 60 of the refrigerator R.

According to the present invention, water is rapidly injected from the injection nozzle 13 and hits the inner wall of the evaporation tube 30 and/or the cyclone cylinder part 61, and the impact causes a large amount of extremely fine water droplets to be formed. These fine water droplets not only make the heat exchange of the air extremely efficient, but also have a high sterilization rate, and the air containing these water droplets does not get wet, so it does not cause overhumidity in the room. Provides excellent air conditioning effects. It is better for water droplets to be as small as possible, but 2 to 15 million water droplets/rd of 0.5μ or less,
Preferably, the number is about 7 to 8 million pieces/-.

The air is thus cooled by the fine water droplets and by the evaporator tubes and brought to approximately saturated relative humidity (e.g. about 7
℃, temperature approximately 1001) is sent out from the outlet pipe 11,
The flow of the discharged air is promoted by the action of the fan 6, and is sent into the annular air passage 15, where it flows downward. In the heat exchange cyclone 3, the temperature of the air,
Of course, the humidity is controlled by the temperature of the evaporation pipe 50, that is, the spiral pipe with a cooling function, and the water to be sprayed.

The air that has proceeded downward through the annular air passage 15 is sent into the heating and humidity control chamber 4 through a communication passage 21 provided at its lower part. The communication path 21 is formed by cutting out the lower part of the heat insulating cylindrical body 2. The air blown into the heating and humidity control cyclone 4 is heated by the spiral heating tube 18 (for example, to about 20° C. and about 60 degrees humidity). In this way, the air whose temperature and humidity are controlled to a predetermined temperature and humidity is sent into the room through the air supply pipe 22.

Air is circulated as described above.

In addition, in seasons with high temperatures such as summer, when high-temperature heating fluid is flowed through the heating pipe 18 of the heating chamber 4, the outlet pipe 11
In addition to dehumidifying the humid air discharged from the room, the air itself is also heated, causing the indoor temperature to rise excessively. Therefore, in order to solve this problem, as shown in Fig. 2, a part of the heating supply pipe 19 from the refrigerator R is exposed outside to lower the temperature of the heating fluid passing through it, thereby increasing the air conditioning efficiency. We succeeded in further increasing this. If necessary, the fan S may be rotated to further enhance the cooling effect.

If the configuration shown in Fig. 2 is adopted, the entire device will be connected to the
The heating tubes are placed outside, which further increases air conditioning efficiency, making it possible to perform extremely clean air conditioning with extremely low energy consumption. If necessary, a filter may be fixedly or detachably attached to the air intake port 8 of the device 1 to filter out large particles, further increasing the effect.

〔Effect of the invention〕

By utilizing extremely fine water droplets, the present invention not only increases heat exchange efficiency and enhances dust removal and sterilization effects, but also
Since the treated air does not become overhumidified, the indoor air does not become wet or overhumidified, making it an excellent indoor air conditioning system. In addition, the dehumidification process in the heating and dehumidifying chamber 4 can be performed at a low energy level, making it possible to provide an energy-saving air conditioning system.

In addition, the refrigerator, or heat pump, and the main body of the dust remover medium conditioning device are organically combined, and the heating supply pipe is placed outdoors, making the entire system compact. Not only does it work, but it also utilizes energy without wasting it, and is highly praised for this aspect as well.

Therefore, the system according to the present invention can not only be used freely at home, but is also particularly suitable as an air conditioning system for laboratories, hospitals, LSI factories, pharmaceutical factories, and precision machinery factories that require ultra-clean environments. There is.

Furthermore, according to the present invention, the air is brought to a saturated humidity level at a low temperature, and then the humidity is naturally adjusted by simply raising the temperature to a predetermined temperature, making it extremely easy to adjust the temperature and humidity of the air. At the same time, when cooling can be achieved reliably, water is injected and blown against the evaporator tube, so that the water cannot freeze on the evaporator tube, and air is always in direct contact with the evaporator tube in a state where there is no freezing. Because of this, the cooling efficiency is extremely high, and since the heating and humidity control chamber is placed around the outer periphery of the heat exchange cyclone, the air conditioner itself becomes very interconnected. Furthermore, in the air conditioner according to the present invention, since the fan is placed downstream of the heat exchange cyclone, that is, above the outlet pipe, the air flow is promoted extremely smoothly. Since it is located on the center line of the replacement cyclone, it has many advantages such as no vibration of the device caused by the fan and almost no noise.
