  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a well-known sensible heat exchanger 33 known in the art, and FIG. 2 is a front view of the sensible heat exchanger 33. The material of the sensible heat exchanger 33 is made of metal such as resin or aluminum.

Since the configuration of the sensible heat exchanger 33 is well known, detailed description will be omitted, but partition walls 34 are arranged at predetermined intervals in the vertical direction, and the upper and lower partition walls 34 are bent in a zigzag shape, for example. A heat conductive plate 35 is provided. The directions of the upper and lower heat conducting plates 35 are orthogonal to each other, and the air flow from the outside is orthogonal as shown by the arrows in the figure.
Further, side plates 36 are disposed at the end portions in the same direction as the air flow direction. Further, the surface of the partition wall 34 and the bent apex portion of the heat conduction plate 35 are fixed, and the heat conduction between the partition wall 34 and the heat conduction plate 35 is facilitated.

In the sensible heat exchanger 33, air flowing in from the direction indicated by the arrow A in FIG. 1 and air flowing in from the direction of the arrow B circulate, and heat exchange is performed due to a difference in the temperature of both the air. If the air indicated by the arrow A is higher than the air indicated by the arrow B, the air indicated by the arrow A has a temperature lower than the temperature flowing in at the portion discharged from the sensible heat exchanger 33.
Here, as is well known, the sensible heat exchanger 33 exchanges only heat and is made of a material that does not allow moisture to pass through, such as a resin, so the humidity is not exchanged.

  Next, the vaporization type latent heat exchanger 11 will be described. FIG. 3 is a perspective view of the vaporization type latent heat exchanger 11, and FIG. 4 is a schematic configuration diagram of the entire cooling device 10 using the vaporization type latent heat exchanger 11. FIG. 5 shows a schematic front view seen from the direction A in FIG.

  The cooling device 10 includes a vaporization type latent heat exchanger 11, which will be described in detail later, a water recovery device 13 that collects water drained from the vaporization type latent heat exchanger 11 through the drain pipe 12, and a water recovery device 13. A water supply pipe 15 for sending the stored water to the vaporization type latent heat exchanger 11 side through the pump 14; a water supply device 16 for supplying water from the water supply pipe 15 to the upper surface of the vaporization type latent heat exchanger 11; It comprises a fan 17 or the like for sucking outside air to the vaporization type latent heat exchanger 11.

In this embodiment, the water in the water recovery apparatus 13 is circulated to the vaporizing latent heat exchanger 11 via the pump 14 and the water supply pipe 15, and the latent heat generated when water is vaporized is used in the vaporizing latent heat exchanger 11. Thus, the temperature of the air taken in the vaporizing latent heat exchanger 11 is lowered.
The water flowing down in the vaporization type latent heat exchanger 11 is recovered by the water recovery device 13 through the drain pipe 12.

The water recovery device 13 is supplied with makeup water such as tap water from a makeup water pipe 20, and a float valve 21 is interposed in the makeup water pipe 20. The float valve 21 is a valve that opens and closes when the float 22 floating on the liquid surface moves in the vertical direction according to the height of the liquid surface.
When the liquid level of the water recovery device 13 becomes a predetermined height or less, the float 22 descends, the float valve 21 opens, and water is supplied from the makeup water pipe 20. Further, when makeup water is supplied and the liquid level reaches a predetermined height or more, the float 22 rises, the float valve 21 is closed, and the supply of water from the makeup water pipe 20 is stopped.

  The water supply device 16 that circulates water from the water recovery device 13 to the vaporization type latent heat exchanger 11 to supply water has substantially the same length as the width direction of the vaporization type latent heat exchanger 11, for example, by drilling a plurality of holes in a pipe. In addition, water is dropped or sprinkled on the upper surface of the vaporizing latent heat exchanger 11 from these holes.

  As shown in FIG. 5, a drainage basin 25 is provided at the lower part of the vaporization type latent heat exchanger 11, and a drainage pipe 12 is connected to the end of the drainage basin 25 so that the vaporization type latent heat exchanger 11 The water that has flowed down is recovered by the water recovery device 13.

Next, the configuration of the vaporization type latent heat exchanger 11 will be described. As shown in FIG. 4, the vaporization type latent heat exchanger 11 is composed of a water retaining material 30 that is sucked and discharged from outside air as indicated by an arrow. The water retaining material 30 is generally called a “cooling pad” and is made of a paper material that is a material containing moisture.
Moreover, this cooling pad is mainly used for lowering the temperature of barns and horticultural facilities, and in Japan, it is widely used in windowless barns and greenhouses for horticulture.

6 to 9 show how to make the water retaining material 30, and the structure of the water retaining material 30 will be described so that the structure of the water retaining material 30 can be easily understood. As shown in FIG. 6, corrugated corrugated sheets 51 are formed by laminating multiple layers, and each corrugated sheet 51 is made of strongly processed paper. In addition, the groove | channel 52 formed in the waveform shape of the corrugated board material 51 and formed continuously becomes an air flow path.
The upper and lower corrugated sheets 51 are alternately combined at an arbitrary angle, for example, around 30 °, with respect to the intake direction, and the lower corrugation of the upper corrugated sheet 51 and the upper apex of the wave of the lower corrugated sheet 51 are combined. The crossing points, that is, the black circles (●) shown in FIG.

  A plurality of corrugated sheet materials 51 are laminated in the water retaining material body 55 shown in FIG. 8, and the water retaining material body 55 is cut with a cutter or the like in the direction indicated by the arrow in the drawing, so that an arbitrary thickness can be obtained. A water retaining material piece 56 is obtained. And as shown in FIG. 9, the water-retaining material 30 of arbitrary magnitude | sizes can be formed by cut | disconnecting with a cutter etc. as shown to the arrow B of the vertical direction and a horizontal direction.

  In addition, the water retaining material 30 can be easily manufactured in any thickness and size, and when the corrugated sheet material 51 is laminated up and down, the corrugated sheet material 51 is inclined and laminated at an arbitrary angle. The inclination angle of each groove 52 of the corrugated sheet material 51 with respect to the intake direction of outside air can also be arbitrarily formed. Moreover, as shown in FIG. 6, the width dimension L and the height dimension H of the groove | channel 52 can be manufactured arbitrarily.

FIG. 10 shows an enlarged cross-sectional view of the main part of the water-retaining material 30 manufactured as described above. From the left, as shown by an arrow, the air is a groove 52 of the water-retaining material 30 (hereinafter, this groove is referred to as “air flow passage”). Pass through).
For example, the air flow passage 52 shown by the solid line rises with an inclination of 30 °, is adjacent to the air flow passage 52 shown by the solid line in the width direction, and the air flow passage 52 shown by the broken line is For example, it is configured to descend with an inclination of 30 °. These air flow passages 52 are formed continuously in the vertical direction and the horizontal direction of the water retaining material 30.

  Water from the water supply device 16 is dripped onto the water retaining material 30 and the water retaining material 30 itself absorbs water to become wet. At the same time, water flows down the surface of the water retaining material 30, that is, the front and back surfaces of each air flow passage 52. Then, the water that has not been absorbed by the water retention material 30 flows along the surface of the water retention material 30 to the water recovery device 13 and is recovered.

  Thus, in the vaporization type latent heat exchanger 11 (water retaining material 30), the temperature of the air sucked in the vaporization type latent heat exchanger 11 can be lowered using the latent heat generated when water is vaporized. It has become.

FIG. 11 shows a state in which the vaporization type latent heat exchanger 11 and the sensible heat exchanger 33 are arranged side by side, and an arrow A indicates the flow of air flowing into and flowing into the vaporization type latent heat exchanger 11 and the sensible heat exchanger 33. Show. An arrow B indicates a flow of air flowing only in the sensible heat exchanger 33 in a direction orthogonal to the arrow A. The fan 41 is for sucking air in the direction of arrow A, and the fan 42 is provided for sucking air in the direction of arrow B.
FIG. 12 shows a schematic configuration diagram of the configuration of FIG.

In FIG. 11, A and C are the outside air on the upstream side. In B which passed through the vaporization type latent heat exchanger 11, the temperature is lower than that of A and the humidity is high. Further, heat exchange is performed with the air from the vaporization type latent heat exchanger 11 in the sensible heat exchanger 33. Therefore, the temperature at the portion that has passed through the sensible heat exchanger 33 is lower than that of the outside air. The humidity is the same as the outside air.
Thereby, temperature can be lowered | hung with the humidity comparable as external air.

  Here, although the temperature in D that has passed through the sensible heat exchanger 33 is higher than the temperature in B that has passed through the vaporization type latent heat exchanger 11, the humidity is the same as that of the outside air. Can be reduced. Since the humidity is high in a, it is difficult to lower the temperature further.

  FIG. 13 shows a state in which the vaporization type latent heat exchanger 11a is arranged on the downstream side of the sensible heat exchanger 33 shown in FIG. In addition, the structure of the newly arrange | positioned vaporization type latent heat exchanger 11a is the same as the vaporization type latent heat exchanger 11. The temperature of the air at E that has passed through the vaporization type latent heat exchanger 11a disposed downstream of the sensible heat exchanger 33 is lower than the temperature of D that has passed through the sensible heat exchanger 33, and the humidity is higher than that of D. It becomes.

  The rate of decrease in the temperature of the upstream a in the vaporization type latent heat exchanger 11 and the downstream of the b, and the rate of decrease in the temperature of the upstream d in the other vaporization type latent heat exchanger 11a and that of the downstream e are almost the same. is there. Therefore, although the temperature of D is higher than the temperature of A, the temperature at O can be made considerably lower than the temperature at A by passing through the vaporization type latent heat exchanger 11a. In this way, the temperature of the air from the sensible heat exchanger 33 can be further lowered by the vaporization type latent heat exchanger 11a.

  FIG. 14 shows a case where three combinations of the vaporization type latent heat exchanger 11 and the sensible heat exchanger 33 are arranged. In addition, although drawn in the state which each separated for convenience of explanation, in fact, each heat exchanger is in the adjacent state.

  The temperature of the air that has passed through the vaporizing latent heat exchanger 11 is T2, and the temperature T3 of the air that has been heat-exchanged by the sensible heat exchanger 33 is higher than the temperature T2. Moreover, the temperature T3 of the air heat-exchanged with the vaporization type latent heat exchanger 11b and the sensible heat exchanger 33b is the same as the above. The temperature T4 of the air heat-exchanged by the vaporization type latent heat exchanger 11a is lower than the temperature T3, and the temperature of the air heat-exchanged by the sensible heat exchanger 33a is T5.

When heat exchange is performed between the vaporization type latent heat exchanger 11a and the sensible heat exchanger 33a, the air flowing into the vaporization type latent heat exchanger 11a is exchanged with the vaporization type latent heat exchanger 11 and the sensible heat exchanger 33a in the preceding stage. And the air flowing into the sensible heat exchanger 33a is the air that has been heat-exchanged between the vaporizing latent heat exchanger 11b and the sensible heat exchanger 33b in the preceding stage. The temperature T5 of the air that has passed through the heat exchanger 33a can be further reduced. The humidity of the air that has passed through the sensible heat exchanger 33a is the same as that of the outside air.
Thus, in the configuration of FIG. 14, the temperature can be lowered with the same degree of humidity as the outside air. Moreover, since it passes through the plurality of heat exchangers, the temperature can be further lowered.

  FIG. 15 shows a case where a vaporizing latent heat exchanger 11c is provided on the downstream side of the sensible heat exchanger 33a with respect to the configuration of the heat exchanger of FIG. In this combination, the vaporization type latent heat exchanger 11c is provided at the last stage, so that the temperature T6 (<T5) of the air from the vaporization type latent heat exchanger 11c can be further reduced. In addition, the humidity of the air from the vaporization type latent heat exchanger 11c is higher than the outside air.

FIGS. 16 and 17 show a heat exchange device 44 comprising a vaporization type latent heat exchanger 11, a sensible heat exchanger 33, and a vaporization type latent heat exchanger 11a on the upstream side of the intake air of the condenser 3 of the outdoor unit 1 of the air conditioner. The schematic block diagram at the time of installing is shown. This heat exchange device 44 has the same configuration as shown in FIG.
17 and 18 depict the vaporization-type latent heat exchanger 11, the sensible heat exchanger 33, and the vaporization-type latent heat exchanger 11a in series for easy understanding, but in actuality, the arrangement shown in FIG. It has a configuration.

Yes. In the present embodiment, the cooling fan 4 is provided on the upper portion of the case 2, but the cooling fan 4 may be provided at a position facing the condenser 3.

  As shown in FIGS. 16 and 17, the sensible heat exchanger 33 of the heat exchange device 44 is approximately the same as or slightly larger than the size of the condenser 3. It is a size that covers the air suction surface.

FIG. 18 shows a well-known refrigeration cycle. The refrigeration cycle includes a condenser 3, a compressor 5, an evaporator 6 in an indoor unit installed indoors, an expansion valve 7, and the like. Connected.
During the cooling operation, the refrigerant in the refrigerant pipe 8 is compressed by the compressor 5, and the refrigerant becomes a high-temperature gas. The refrigerant 3 is kept at a constant temperature by the latent heat of water when the condenser 3 is vaporized by the cooling fan 4. The refrigerant gas is liquefied by being lowered. The refrigerant pressure is suddenly lowered by the expansion valve 7 and is cooled by the latent heat of the refrigerant gas. The temperature of the room is exchanged by the evaporator 6, and the cool air is sent from the indoor unit to the room for cooling. .

  In FIG. 18, since the water supply device 16 is disposed above the vaporization type latent heat exchangers 11 and 11a, water is supplied to the water supply device 16 through the pipes 15a and 15a branched from the water supply pipe 15. ing.

  16 and 17, the configuration of the heat exchange device 44 in the case of FIG. 13 is used, but the heat exchange device 44 in any of FIGS. 11, 14, and 15 may be used. It is.

  As described above, by arranging the heat exchange device 44 including the vaporization type latent heat exchanger 11 and the sensible heat exchanger 33 on the upstream side of the condenser 3 of the outdoor unit 1, air having a low temperature is supplied to the condenser 3. You can guess. Thereby, the condenser 3 can be efficiently cooled even at high temperatures in summer, and the cooling efficiency can be improved.
