Description

  The present invention relates to an indirect vaporization type air conditioner including an air conditioning core unit in which a wet channel for causing a vaporization phenomenon and a dry channel for passing air to be cooled are alternately arranged.

  When the air is humidified, a vaporization phenomenon occurs and latent heat is taken away, whereby the temperature of the air is cooled to the wet bulb temperature of the air. However, at the same time, the air to be cooled is humidified. This principle is widely known as humidification cooling, and a vaporization-type cooler using it is widely made and sold. When humidification of the released air is not desired, the humidified cooling zone (wet channel) and the zone through which the air to be cooled (dry channel) is separated, and the temperature cooled in the humidified cooling zone is heat exchanged Thus, a method of transmitting only to the zone of the air to be cooled and cooling only the sensible heat of the air in the zone to be cooled, so-called indirect vaporization cooling is performed (see, for example, Patent Document 1).

Japanese Patent No. 4565417

  Note that there are three types of combinations of air flow in the wet channel and the dry channel: counter flow, parallel flow, or cross flow. Among them, although the counter flow is the best for the heat exchange efficiency, there is a problem that when applied to an indirect vaporization air conditioner, the flow path of the vaporized air becomes complicated and the pressure loss increases. .

The plastic material constituting the first plastic substrate and the second plastic member is configured such that a pair of liners are disposed with a gap between the cores, and the pair of liners is partitioned by the cores. In addition, a continuous communication space is formed in one direction, and a wet channel is formed between the first plastic substrates in the air conditioning core. In addition to functioning, the communication space in the first plastic substrate functions as a dry channel, and a dry inlet and a dry outlet are provided in the extending direction of the communication space in the first plastic substrate. The wet layer is provided at least in part, and the second plastic member is disposed on the peripheral edge of the first plastic substrate on the dry inlet side and the dry outlet side, and air flowing through the wet channel is dry. -A pair of shielding members that close between the first plastic substrates in order to prevent mixing into the channel, and a wet inlet and a wet outlet are provided in a direction that intersects the opposing direction of the pair of shielding members It is.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  An indirect vaporization type emptying device according to an embodiment of the present invention performs air conditioning using a vaporization phenomenon, and includes a wet channel 11 for causing the vaporization phenomenon, and a dry channel for passing air to be cooled. An air conditioning core unit 10 in which channels 12 are alternately arranged is provided.

  FIG. 1 shows the configuration of the air conditioning core unit 10. 2 to 6 show the configuration of the basic unit 20 constituting the air conditioning core unit 10, FIG. 2A shows the configuration of the basic unit 20 viewed from one side, and FIG. 2B shows the basic unit. The unit 20 is viewed from the opposite side. The air conditioning core unit 10 has a basic unit 20 in which a second plastic member 22 made of a plastic material such as polypropylene is disposed on one surface side of a first plastic substrate 21 made of a plastic material such as polypropylene. The basic unit 20 is configured by laminating the first plastic substrate 21 and the second plastic member 22 alternately.

  The plastic material that constitutes the first plastic substrate 21 and the second plastic member 22 includes a pair of liners 31 that are disposed with a space between the cores 32, and the cores 32 are interposed between the pair of liners 31. It is preferable that a communication space that is continuous in one partitioned direction is formed. The core 32 is formed in, for example, a wave shape, and the unevenness is extended in a direction perpendicular to the direction in which the unevenness is repeated in the wave shape to form a communication space between the pair of liners 31. The core 32 is not limited to a wave shape, and a continuous communication space in one direction may be formed between the pair of liners 31. Examples of such a shape include corrugated cardboard.

  In the air conditioning core unit 10, the space between adjacent first plastic substrates 21 functions as the wet channel 11, and the communication space in each first plastic substrate 21 functions as the dry channel 12. . The thickness of the first plastic substrate 21 and the second plastic member 22 is preferably about 2 mm to 5 mm, for example, and the thickness of the liner 31 is preferably about 0.1 mm to 0.5 mm, for example.

  A dry inlet 12A is provided on one side of the first plastic substrate 21 in the extending direction of the communication space, and a dry outlet 12B is provided on the other side. Wet layers 23 for holding water at least partially are provided on both outer surfaces of the first plastic substrate 21.

  The wetting layer 23 is preferably composed of, for example, a woven fabric, a nonwoven fabric, or electrostatic flocking made of a hydrophilic material. Further, it is more preferable to apply a water absorbing agent such as titanium oxide or silica gel to the wet layer 23 in order to improve the spread of water. The thickness of the wet layer 23 is preferably about 0.2 mm to 0.5 mm, for example. For example, the wet layer 23 is bonded to the outer surface of the first plastic substrate 21 by bonding or thermocompression bonding. As for the supply of water to the wet layer 23, a supply pipe (not shown) for supplying water to the wet layer 23 may be provided, or water may be sprayed from above.

  The second plastic member 22 is disposed on the peripheral edge of the first plastic substrate 21 on the dry inlet 12A side and the dry outlet 12B side, for example, and air flowing through the wet channel 11 is mixed into the dry channel 12 In order to prevent this, a pair of shielding members 22 </ b> A that close between adjacent first plastic substrates 21 are provided. For example, the shielding member 22 </ b> A is disposed so that the extending direction of the communication space in the shielding member 22 </ b> A intersects the extending direction of the communication space in the first plastic substrate 21. Specifically, it is preferable that the extending directions of the communication space of the shielding member 22A and the communication space of the first plastic substrate 21 are orthogonal to each other. As a result, the wet channel 11 is formed between the adjacent first plastic substrates 21, and the wet inlet 11 </ b> A is provided in one of the directions intersecting the opposing direction of the pair of shielding members 22 </ b> A, for example, in the orthogonal direction. A wet outlet 11B is provided.

  The facing direction of the wet inlet 11A and the wet outlet 11B is a direction that intersects, for example, a direction orthogonal to the facing direction of the dry inlet 12A and the dry outlet 12B. The air flow in the channel 12 is crossed, eg orthogonal.

  Further, the second plastic member 22 is, for example, at the peripheral portion of the first plastic substrate 21 at the peripheral portion of the first plastic substrate 21 and the wet inlet member 22B disposed on at least part of the wet inlet 11A side. It is preferable to have a wet outlet member 22C disposed at least in part on the wet outlet 11B side, and an intermediate member 22D disposed between the wet inlet member 22B and the wet outlet member 22C.

  The wet inlet member 22B and the wet outlet member 22C are for regulating the air flow and suppressing fluttering of the wet inlet 11A and the wet outlet 11B. The intermediate member 22 </ b> D is for ensuring the thickness of the wet channel 11, that is, the interval between the first plastic substrates 21. The extending direction of the communication space in the wet inlet member 22B, the wet outlet member 22C, and the intermediate member 22D is preferably, for example, the facing direction of the wet inlet 11A and the wet outlet 11B.

  One or more intermediate members 22 </ b> D are preferably provided in the opposing direction of the wet inlet 11 </ b> A and the wet outlet 11 </ b> B, and the number can be arbitrarily set according to the size of the first plastic substrate 21. Further, the intermediate member 22D may be provided continuously from one shielding member 22A to the other shielding member 22A in the opposing direction of the pair of shielding members 22A, or may be provided in a part thereof. When it is provided in a part, it may be provided continuously in part or may be provided intermittently.

  The shielding member 22A, the wet inlet member 22B, the wet outlet member 22C, and the intermediate member 22D are preferably attached to the first plastic substrate 21 with a waterproof adhesive 24, for example. In FIG. 6, the position of the adhesive 24 is indicated by shading. Thereby, in the shielding member 22A, it is possible to prevent water supplied to the wet layer 23 from being transferred to the dry channel 12 through the wet layer 23. Further, in the wet outlet member 22C and the intermediate member 22D, when the water supplied to the wet layer 23 falls down along the wet layer 23, the adhesive 24 is prevented from moving downward and moves sideways. As a result, the residence time in the wet layer 23 can be extended, and the cooling function can be maintained with a small amount of water.

  It is preferable that 22 A of shielding members are affixed by the adhesive agent 24 continuously from the wet inlet 11A to the wet outlet 11B. In the wet outlet member 22C and the intermediate member 22D, it is preferable to provide a region where the adhesive 24 is not attached to a part in order to move water. For example, when the wet outlet member 22C and the intermediate member 22D are continuously provided from one shielding member 22A to the other shielding member 22A, the adhesive 24 is intermittently applied in the facing direction of the pair of shielding members 22A. It is preferable to paste. In addition, it is preferable that the air-conditioning core part 10 is arrange | positioned by making the opposing direction of wet inlet 11A and wet outlet 11B into a perpendicular direction.

  The air conditioning core unit 10 can be manufactured, for example, as follows. First, the second plastic member 22 is disposed with the adhesive 24 or the like at a predetermined position on the one surface side of the first plastic substrate 21 on which the wet layer 23 is formed. The second plastic member 22 may be directly disposed on the first plastic substrate 21 with the adhesive 24 or the like, or may be disposed with the adhesive 24 or the like with the wet layer 23 interposed therebetween. The basic unit 20 obtained in this manner is stacked so that the first plastic substrate 21 and the second plastic member 22 are alternately positioned, and the air conditioning core unit 10 is formed. The stacked basic units 20 may be fixed with an adhesive or the like, or may be fixed using a fixing member.

The air in the dry channel 12 is heated by heat exchange with the air in the wet channel 11. For example, the air in the wet channel 11 is exhausted to the outside of the air conditioning target room, and the heated air in the dry channel 12 is supplied to the air conditioning target room. Thereby, in the winter season when the temperature is low, the air-conditioning target room can be heated using the heat of the heated air-conditioning target room. Further, as shown in FIG. 7D, air outside the air-conditioning target room such as outside air is circulated through the wet channel 11 to be supplied into the air-conditioning target room, and the air inside the air-conditioning target room is circulated through the dry channel 12. Then, the air may be exhausted outside the air-conditioned room.

  In the case shown in FIG. 8A, water is supplied to the wet layer 23 to allow air outside the air-conditioned room such as outside air to flow through the wet channel 11, and the air inside the air-conditioned room passes through the dry channel 12. Circulate. The air in the wet channel 11 is humidified by a vaporization phenomenon and is heated by heat exchange with the air in the dry channel 12. The humidified and heated air in the wet channel 11 is supplied to the air-conditioned room, and the air in the dry channel 12 is exhausted outside the air-conditioned room. As a result, the air-conditioned room can be humidified in winter when the humidity is low. Further, as shown in FIG. 8B, the air in the dry channel 12 may be supplied to the air-conditioned room. Further, as shown in FIG. 8C, air inside the air-conditioning target room is circulated through the wet channel 11 to supply air into the air-conditioning target room, and air outside the air-conditioning target room such as outside air is circulated through the dry channel 12. It is possible to supply air into the air-conditioned room.

  Thus, according to the present embodiment, the air conditioning core unit 10 is configured by laminating the basic unit 20 in which the second plastic member 22 is disposed on the one surface side of the first plastic substrate 21.
