In order to solve the above-mentioned problems, the present invention relates to an outer frame in which a plurality of gas-liquid contact type fillers for heat exchange are suspended from an upper water tank at intervals. The air flow passing between these packing materials and the liquid flowing down on the surface of each packing material are directly contacted in a cross-flow system by adjusting the temperature of this air flow and adjusting its humidity. In the air humidifier or cooler, the gas-liquid contact type filler for heat exchange is formed by integrally forming a water-absorption wet layer on the front and back surfaces of a synthetic resin sheet-shaped substrate, and the water tank has a cross section. It has a gutter-like shape with an open upper part, and this water tank is fitted substantially horizontally through the gas-liquid contact fillers near the top of the gas-liquid contact fillers arranged in parallel. At least one part of the gas-liquid contact type filler is added to the liquid in the water tank. While being soaked, a carry-over blocking portion is formed along the side edge of the gas-liquid contact type filler on the downstream side with respect to the air flow, and the adjacent gas-liquid contact type is located around the water tank. Spacers are arranged in the gaps between the fillers in parallel with the gas-liquid contact filler and in close contact with each other so as to be fitted in the water tank, and between the both ends of the water tank and the outer frame. An air humidifier or cooler characterized in that a non-absorptive end plate is provided, and a space continuous in the longitudinal direction at the fitting portion of the gas-liquid contact type filler and the upper water tank is hermetically formed. .

In the air humidifier or cooler of the present invention, the gas-liquid contact filler is made of a corrugated plate, and the carry-over preventing portions are arranged at intervals in the height direction of the gas-liquid contact filler. It is preferably composed of a plurality of vertical slits, and these vertical slits are preferably formed in a valley portion of the corrugated plate.

In the air humidifier or cooler of the present invention, the immersed portion of the gas-liquid contact type filler is an inverted triangular claw with its downwardly-pointed tip end immersed in the liquid in the water tank at the windward side of the air flow. It may consist of parts. In the air humidifier or cooler of the present invention in which the inverted triangular claw portions are provided at two or more locations, the windward claw portion of the air amount is longer than the leeward claw portion, and It is desirable that the tip of the claw portion is lower than the tip of the leeward claw portion.

The edge height of the water tank in the air humidifier or cooler of the present invention is lower on the windward side and higher on the leeward side according to the height of the claw portion of the inverted triangle described in claim 3. Sometimes there is. It is preferable that the wet layer in the air humidifier or cooler of the present invention is made of a moisture absorbent cloth.

In the air humidifier or cooler of the present invention, it is desirable that the spacer be a suction aid such as a sponge material.

In the fitting portion between the upper water tank and the gas-liquid contact type filler in the air humidifier or cooler of the present invention, an opening is formed in the vicinity of the lower surface of the upper water tank through the front and back surfaces of the gas-liquid contact type filler. It is preferable that a part of the spacer material on both sides of the gas-liquid contact type filler located on the front and back surfaces of the spacer material is in mutual contact with each other through this opening to form a liquid distribution passage.

[0010]

Next, the operation of the air humidifier or cooler according to the first aspect of the present invention constructed as described above will be explained together with the method of use. A) When the present invention is used as a humidifier in combination with an air conditioner (see FIG. 9) During heating, the fan of the air conditioner is driven, and indoor air is taken into the casing from the air intake port to generate heat. After the air flow is heated by the exchanger, it is passed between the gas-liquid contact type fillers hanging from the upper water tank. During this passage, when the liquid in the upper water tank is sucked up from a part of the gas-liquid contact type filler immersed in at least one place in the upper water tank according to the humidity, the liquid is vaporized. The liquid diffuses left and right in the wet layer of the liquid contact type filler, and sequentially flows down along the gas-liquid contact type filler by gravity, forming a wetting wall on the outer surface of the gas-liquid contact type filler. This wetted wall is brought into direct contact with the air flow, and the relative humidity of the air whose temperature is adjusted by evaporation of water is, for example, 55% to 7%.
Increase to about 7% to optimize the indoor living environment in winter. At this time, since the upper water tank is fitted through these fillers, its position is not displaced in the air flow direction by the air flow, and it is maintained at a predetermined lifting position, and the vibrations associated with the displacement do not occur. Less likely to occur.

Further, in the fitting portion of the upper water tank and the filler, no air flow is generated, the liquid is sucked up smoothly, and the detection of silica, calcium, etc. due to the evaporation of the liquid does not occur. When water is supplied from the dry state to the gas-liquid contact type filler from the upper water tank at once, the space that is sealed by the end plate and is formed at the fitting portion between the upper water tank and the filler is filled with liquid. A large amount of liquid overflows from the upper water tank on the front and back surfaces of the filler all at once, and flows down to form a water film. At the time of this water supply, since the filling material front and back surfaces are in a dry state, it takes some time to absorb water, and the water film flowing down on the filling material front and back surfaces by the cross flow Is blown to the downstream side by the air flow flowing as, and is blocked by the carry-over blocking portion on the downstream side of the packing material, and is not scattered as water droplets, but flows down to the front and back surfaces of the packing material of the blocking section, and gradually the entire wet layer in the meantime. Becomes a wet state, a water film is no longer formed on the surface of the filling material, and water supply is continued without carryover. By flowing a large amount of liquid, which can be said to be excessive, in this way, the heated room is brought to an appropriate temperature state in a short time. Further, the spacer ensures an air passage between the adjacent gas-liquid contact type fillers hanging from the upper water tank. In this case, in the fitting portion between the spacer and the upper water tank, as in the case of the filler, no air flow is generated, silica, calcium, etc. do not precipitate due to evaporation of the liquid, and the liquid is smoothly sucked up. Be seen.

In the invention described in claim 2, in addition to the operation of the specific invention, the water film is filled with the air flow by the vertical slit group provided in the valley portion of the corrugated plate when a large amount of liquid is supplied. It is blocked from being blown to the downstream edge of the material, and the water accumulated in this portion flows down along the edge of the vertical slit, and even if a part of it becomes a water drop, it prevents the carry-over. Water droplets jumping over the slits are trapped at the downstream side edge of the packing material on the downstream side of the vertical slits and further flow down at this portion, but at this portion, the water film is not continuous from the upstream side, so it is blown up. A small amount of water is left behind, and when it falls, it wets its surface layer, and water film formation hardly occurs. In this way, the front and back surfaces of this filling material are quickly wetted and the humidity is adjusted.

In the invention described in claim 3, the dipping portion of the gas-liquid contact type filler is an inverted triangular shape in which the downward pointed tip thereof is nearer to the windward side of the air flow and soaked in the liquid in the water tank. Since it comprises the claw portion, it has the following function in addition to the function of the invention according to the first aspect. That is, when the water level is low, the amount of liquid sucked up from the inverted triangular claw portion is suppressed to a small amount, and the degree of humidity adjustment is low, and when the water level is high, the inverted triangular claw portion and the liquid water surface. The contact area with the claw portion is increased, and the amount of liquid sucked from the claw portion is increased. Therefore, by adjusting the water level in the upper aquarium. The water content of the liquid sucked up by the gas-liquid contact type filler and flowing down by gravity is adjusted, and the humidity of the air flow flowing between the fillers is adjusted. In addition, when a large amount of water is supplied at the start of water supply, the space of the fitting portion between the filling material in which the claw portion is formed and the water film is filled with liquid, and when the claw portion is submerged, the liquid is discharged from the upper tank. It is supplied all at once onto the filler.

In the invention described in claim 4, the inverted triangular claw portion is provided at two or more places, and the windward side claw portion is longer than the leeward side claw portion, and this windward side claw portion is longer. The pointed portion of the claw portion is lower than the pointed portion of the claw portion on the leeward side, that is, closer to the bottom portion of the water tank. Therefore, in addition to the action of the invention according to claim 1 or 2, do. That is, when the water level is low, the liquid is not sucked up from the leeward side, the liquid is sucked up only from the claw portion on the windward side, and the degree of humidity adjustment is reduced,
When the water level rises, the liquid is sucked up from both the windward side and the leeward side of the claw portion to increase the suctioned amount, and the degree of humidity adjustment is increased. Furthermore, by giving priority to the suction on the windward side, a wet wall that contacts the air flow is formed in the entire region of the gas-liquid contact type filler, and a blank area (dead area) without a wet wall does not occur on the windward side. Further, when a large amount of water is supplied at the start of water supply, water is supplied all at once from the space of the fitting portion with these claw portions submerged.

In the invention described in claim 5, the edge height of the water tank is lower on the windward side and higher on the leeward side according to the height of the claw portion of the inverted triangle described in claim 4. Therefore, in addition to the actions of the invention described in claims 1 to 4, the following actions are performed. That is, when the water level becomes higher than the edge height on the windward side of the aquarium, a part of the liquid begins to overflow beyond the side wall on the windward side of the aquarium, and the liquid is sucked up from the claw portion of the inverted triangle on the windward side. At the same time, the wetting wall on the windward side is positively formed on the outer surface of the gas-liquid contact type filler by the gravity flow-down method.

In the invention described in claim 6, since the wetting layer is made of a hygroscopic cloth, in addition to the action of the invention described in the first to fifth aspects, the water absorbed in the wetting layer is Evaporate by the air in contact with and humidify the air. In the invention described in claim 7, since the moisture absorbent cloth is a non-woven fabric, the invention is described in any one of claims 1 to 6.
It operates similarly to the described invention.

In the invention described in claim 8, since the spacer serves as a suction assisting material such as a sponge material, the spacer is interposed between the gas-liquid contact type fillers so that the liquid is capillarized. The liquid is sucked up and replenished to the front and back surfaces of the adjacent gas-liquid contact type filler, and contributes to the humidity adjustment. Further, even when a large amount of water is supplied, the spacer contributes to the water supply action to the filling material.

In the invention described in claim 9, in the fitting portion between the upper water tank and the gas-liquid contact filler, an opening is formed through the front and back surfaces of the gas-liquid contact filler in the vicinity of the lower surface of the upper water tank. A part is provided, and a part of the spacers on both sides located on the front and back surfaces of the gas-liquid contact type filler contact each other through this opening to form a liquid distribution passage. In addition to the actions of the invention described in claims 1 to 8, the following actions are performed. That is, through the openings formed in the gas-liquid contact type filler, the adjacent spacers mutually supply the sucked liquids to each other to supplement the shortage of the liquids, thereby making it possible to prevent the filling material between the adjacent absorption aids. Form sufficient wetting walls on the front and back surfaces.

(B) When the present invention is used as a cooler by being incorporated in a cross flow type cooling tower (see FIG. 10). Cooling water (hot water) sent from the load part (refrigerator, etc.)
Is sent into the upper water tank and is temporarily stored in the upper water tank. Then, the cooling water in the upper water tank is sucked up from a part of the gas-liquid contact type filler immersed in the upper water tank according to the humidity by a capillary phenomenon, and the cooling water is sucked from the gas-liquid contact type filler. It is made to flow down along the outer surface of, and a wetting wall is formed on the outer surface of this gas-liquid contact type filler. In this state, an air flow is made to flow through the gas-liquid passage between the adjacent gas-liquid contact fillers in the horizontal direction perpendicular to the cooling water flow direction. The cooling water flowing on the surface of the gas-liquid contact type filler and forming the wetting wall is in direct contact with the air flow, and the cooling water is cooled by the latent heat of vaporization. The cooling water thus forming the wetting wall is directly cooled by heat exchange with the air flow during its flow and then sent from the lower water tank of this cooling tower to the load part such as a refrigerator to perform work. After finishing the temperature rise, it is returned to the upper water tank,
It is cooled again and reused. At this time, the action of sucking up the cooling water and the action of preventing the carry-over in the invention described in each of the claims are the same as those in the above case a).

C) When the present invention is used as a cooling panel (see FIG. 11). This air humidifier or cooler is attached to one wall surface of the building together with a frame having a lower drain gutter, and a blower is provided on the opposite wall surface. Next, the liquid is sucked from the upper water tank onto these fillers, and the wet layers formed on the plate surfaces of the respective fillers are absorbed by water and flow down by gravity to form wet walls on the entire surface of the heat exchange zone, that is, the heat exchange area. On the other hand, the blower is operated to reduce the air pressure in the building, and the outside air is drawn into the building through the gas-liquid passage between these fillers, and the air and the wet wall are directly contacted while passing through the gas-liquid passage. It raises the humidity of the air, raises the temperature, and lowers the temperature of the liquid. This cooled liquid at an appropriate temperature is received by the lower drainage gutter, and is circulated for use.

[0026]

The present invention is constructed and operated as described above.
The effects of the invention described in 1. will be described below. First, when used in combination with an air conditioner, when a large amount of liquid is supplied to this gas-liquid contact type filler from the upper water tank at the initial stage of operation, it is inserted into the fitting section between the upper water tank and the gas-liquid contact type filler. The formed space is filled with liquid, and a large amount of liquid overflows from the upper water tank on the front and back surfaces of the filling material at once, and flows down to form a water film. As a result, the filling material in a dry state is It takes a certain amount of time for the front and back surfaces to absorb water, and by the time this water absorption is completed, the water flowing down on the front and back surfaces of this filling material flows down as a water film, and due to the air flow flowing as a cross flow, Although the water film tends to be blown to the downstream side, the carryover blocking portion can capture the water droplets carried by this air flow, and the carryover blocking portion causes the water droplets to flow down, while the wet layer on the front and back surfaces of the filler is formed. Gradually wet , By a stream of scattered it becomes water droplets from the filling material downstream edge and eradicate such to dissipation chamber. Along with this, an appropriate humidity can be obtained in a short time. Depending on the humidity, the liquid in the upper water tank is sucked up by a capillary phenomenon from a part of the gas-liquid contact type filler immersed in at least one place in the upper water tank, and the liquid is filled in the gas-liquid contact type filler. By flowing down along the outer surface of the material with power, a wetted wall can be sufficiently formed on the outer surface of the gas-liquid contact type filler, and in this state, the fan of the air conditioner is operated and the indoor air Is sucked into the casing of this air conditioner and flowed between the gas-liquid contact fillers adjacent to each other, and the horizontally flowing air and the wet wall are directly contacted with the gas-liquid passage formed between the adjacent gas-liquid contact fillers. Then, the temperature of the air is adjusted by evaporation of water, the humidity is adjusted to an optimum value and the air is blown out from the casing of the air conditioner into the room to optimize the indoor living environment in winter. it can.

Further, since the upper water tank is fitted substantially horizontally by penetrating the gas-liquid contact type filler and the spacer, the upper water tank can also serve as a support member for these filler and spacer, and the fitting allows air to enter. These fillers do not displace in the flow direction of, and the vibration can be reduced. Further, by the spacer, a plurality of gas-liquid contact type fillers can be hung down from the upper water tank at a predetermined interval, and an air passage can be secured between the hanging gas-liquid contact type fillers adjacent to each other. You can The place where the air flow passes is lower than the position where the upper water tank penetrates through the gas-liquid contact filler and is a gap between the gas-liquid contact filler hanging from the upper water tank. Since the air flow is blocked by the upper water tank in the liquid suction part, evaporation of the liquid suction part does not occur at all, silica, calcium, etc. in the liquid do not precipitate, and this suction part is always good. In such a state, the liquid can be sucked up without an appropriate amount of resistance, and the wet layer of the gas-liquid type filler can be flowed down by gravity while wetting the wet layer to form a wet wall appropriately.

In the invention described in claim 2, the vertical slit group provided in the valley portion of the corrugated plate prevents the water film from being blown by the air flow to the downstream side edge of the filler, A part of it becomes a water droplet and jumps over the vertical slit, but this water droplet can be captured at the filler portion on the downstream side of the vertical slit, and since this water droplet has a small amount of water, a water film is formed on the surface of this portion. Without doing so, it gradually wets and does not become a water droplet from the downstream edge of the air stream and scatter, and the carry-over can be prevented. In the invention described in claim 3, the immersion portion of the gas-liquid contact type filler is an inverted triangular claw portion whose tip portion is immersed in the liquid in the water tank at the windward side of the air flow. In addition to the effects of the invention described in claims 1 and 2, the following effects are exhibited. That is, when the water level of the liquid in the water tank is low, the suction amount of the liquid from the claw portion of the inverted triangle is suppressed to a small amount, the degree of humidity adjustment is lowered, and when the water level is high, the inverted triangle It is possible to increase the contact area between the claw portion and the liquid water surface, increase the amount of liquid sucked from the claw portion, and increase the degree of humidity adjustment.

Further, since this claw portion is an inverted triangle, the contact area between the liquid and the claw portion can be expanded as the water level rises, and the higher the water level, the greater the amount of liquid sucked up from this claw portion. Therefore, the humidity can be increased. The claw portion of the inverted triangle can be easily formed by punching the upper part of the gas-liquid contact type filler or by vacuum forming, and the weight of the gas-liquid contact type filler can be reduced.
Further, since the claw portion of the inverted triangle is located on the windward side, in the gas-liquid contact type filling material, the liquid can be positively flowed toward the primary side of the air flow by the gravity downflow method, and the air flow It is possible to avoid a decrease in the difficulty of forming a wet wall on the intake side, and it is possible to sufficiently protect the humidity control of the air flow.

In the invention described in claim 4, the inverted triangular claw portions are provided at two locations, and the windward claw portion of the air flow is longer than that of the leeward claw portion.
Moreover, since the tip end of the windward claw portion is lower than the tip end of the leeward claw portion, that is, closer to the bottom of the water tank, in addition to the effects of the inventions of claims 1 to 3, , Has the following effects. That is, when the water level is low, the liquid is not sucked up from the leeward side, and the liquid is sucked up only from the claw portion on the windward side, which reduces the degree of humidity adjustment and increases the water level. Can suck up the liquid from both the windward side and leeward side claw portions to increase the amount of sucking up the liquid, thereby increasing the degree of humidity adjustment. Furthermore, since the suction of the liquid on the windward side is prioritized, a uniform wetting wall can be formed over the entire area of the gas-liquid contact type filler, and there is no blank area (dead area) on the windward side where there is no wetting wall. In addition, the contact area between the air flow and the liquid and the time can be increased.

In the invention described in claim 5, the edge height of the water tank is lower on the windward side and higher on the leeward side in accordance with the height of the claw portion of the inverted triangle described in claim 4. Therefore, in addition to the effects of the invention described in claims 1 to 4, the following effects are exhibited. That is, when the water level becomes higher than the height of the windward side of the aquarium, over the side wall on the windward side of the aquarium, a part of the liquid can be overflowed, and with the liquid sucked from the claw portion of the inverted triangle on the windward side, A wetting wall on the windward side can be formed on the outer surface of the gas-liquid contact type filler.

In the invention described in claim 6, since the wetting layer is made of a hygroscopic cloth, in addition to the effects of the inventions set forth in claims 1 to 5, water absorbed in the wetting layer It can be vaporized by the air in contact with and humidify the air. In the invention described in claim 7, since the moisture absorbent cloth is a non-woven fabric, the same effect as the invention described in any one of claims 1 to 6 can be obtained.

In the invention described in claim 8, since the spacer is a wicking aid made of a sponge material or the like, the spacer is provided between the gas-liquid contact type fillers so that the liquid is capillarized. The liquid can be sucked up by, and this liquid can be replenished to the back surface of the adjacent gas-liquid contact type filler, which can contribute to the humidity adjustment.
Further, even when a large amount of water is supplied, the spacer can promote the water supply to the filling material. In the invention described in claim 9, in the fitting portion between the upper water tank and the gas-liquid contact type filling material, an opening is provided in the vicinity of the lower surface of the upper water tank through the front and back surfaces of the gas-liquid contact type filling material. There is a part of the spacers on both sides of the gas-liquid contact type filling material, which are located on the front and back surfaces of the gas-liquid contact type filling material, and forms a liquid distribution passage. Adjacent spacers should mutually supply suction liquid to each other through the openings formed in the filling material, and supplement the shortage between them to form sufficient wetting walls on the front and back surfaces of the filling material of the adjacent spacers. You can

Next, when the air humidifier or cooler according to the present invention is used by incorporating it in a cross flow type cooling tower, the suction effect of the cooling water is absorbed by the liquid when it is installed in the air conditioner. It is possible to obtain the same effect as that of the above, and it is possible to cool the cooling water by direct contact with the air flow. Further, when used as a cooling panel, the cooling water can be cooled in the same manner as in the case of being incorporated in the cooling tower.
