The patent document 1 has a configuration as shown in FIGS. FIG. 14 shows a schematic configuration of the condenser air cooling device when the auxiliary cooling device 10 is installed on the upstream side of the intake air of the outdoor unit 1, and FIG. 15 is a schematic view seen from the direction A in FIG. A front view is shown.
Since the outdoor unit 1 has a well-known configuration, a detailed description is omitted, but a condenser 3 is disposed on one side of the case 2 of the outdoor unit 1, and a cooling fan 4 is provided on the upper side of the case 2. Yes. In the illustrated example, 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.

  The auxiliary cooling device 10 includes a vaporization type air cooling device 11, a water recovery device 13 that collects water drained from the vaporization type air cooling device 11 via the drain pipe 12, and a water recovery device 13 that stores the water. A water supply pipe 15 that supplies water to the vaporization type air cooling device 11 through a pump 14, a water supply device 16 that supplies water from the water supply pipe 15 to the upper surface of the vaporization type air cooling device 11, and the like. Yes.

  In FIG. 14, the water supply pipe 15 is drawn on the right side of the outdoor unit 1, but the actual construction is arranged on the left side of the outdoor unit 1 and piped on the side surface of the vaporization type air cooling device 11. . However, the vaporization type air cooling device 11 of the auxiliary cooling device 10 is arranged in the vicinity of the outdoor unit 1 on the upstream side of the intake air of the condenser 3, but the other water recovery device 13 and the water supply pipe 15 are optional. Placed and constructed at

  As shown in FIG. 15, the vaporization type air cooling device 11 is approximately the same as or slightly larger than the size of the condenser 3, and the vaporization air cooling device 11 defines the air suction surface of the condenser 3. It is the size to cover.

FIG. 16 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. .

Here, the water in the water recovery device 13 is circulated to the vaporization type air cooling device 11 through the pump 14 and the water supply pipe 15, and vaporization is performed using the latent heat generated when water vaporizes in the vaporization type air cooling device 11. The temperature of the air sucked in the type air cooling device 11 is lowered, and the condenser 3 is cooled with the lowered air.
The water flowing down in the vaporization type air cooling device 11 is recovered by the water recovery device 13 through the drain pipe 12.

As shown in FIG. 14, makeup water such as tap water is supplied to the water recovery device 13 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 air cooling device 11 and supplies the water is approximately the same length as the width direction of the vaporization type air cooling device 11. For example, a plurality of holes are drilled in a pipe. In addition, water is dropped or sprinkled on the upper surface of the vaporization type air cooling device 11 from these holes.

  As shown in FIG. 15, a drainage basin 25 is provided at the lower part of the vaporization type air cooling device 11. A drainage pipe 12 is connected to the end of the drainage basin 25, and the vaporization type air cooling device 11 The water that has flowed down is recovered by the water recovery device 13.

Next, the configuration of the vaporization type air cooling device 11 will be described. As shown in FIG. 14, the vaporization type air cooling device 11 includes a water retaining material 30 that is sucked and discharged as indicated by an arrow. The water retaining material 30 is generally called a cooling pad (cooling pad), and is made of a paper material obtained by processing wood chips, polyethylene, and glass fiber, and has been commercially available.
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.

17 to 20 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. In FIG. 17, 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. that bets intersect, that is, bonding the portions of the black circle shown in FIG. 18 (●) with an adhesive, to adhere the upper and lower wave plate 51.

  A large number of corrugated plate materials 51 are laminated in a water-retaining material body 55 shown in FIG. 19, 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. 20, 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. 17, the width dimension L and the height dimension H of the groove | channel 52 can be manufactured arbitrarily.

FIG. 21 is an enlarged cross-sectional view of a main part of the water retaining material 30 manufactured as described above. The condenser 3 is located on the right side of the water retaining material 30, and the air is retained from the left as indicated by the arrow. The groove 52 (hereinafter, this groove is referred to as “air flow passage”).
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.

In particular, as described above as the material of the water retaining material 30, since it is composed of paper quality obtained by processing wood chips, polyethylene, and glass fiber, the water retaining material 30 itself absorbs water and becomes wet, and the water retaining material The temperature of the air sucked into the water retaining material 30 side can be lowered by the latent heat when vaporizing from 30. Thereby, the condenser 3 can be cooled efficiently.
That is, by circulating water through the vaporization type air cooling device 11, the suction temperature of the outdoor unit 1 passing through the vaporization type air cooling device 11 is lower than the outside air temperature due to vaporization latent heat, and the cooling capacity is improved by the humidification effect. You can plan.

Thus, conventionally, by circulating water through the vaporization type air cooling device 11 disposed on the air suction side of the condenser 3 of the outdoor unit 1, the makeup water is only the amount of the evaporated water, I try to suppress the rise.
Moreover, since the power consumption of the whole air conditioner can be suppressed by cooling the condenser 3, the electricity cost of the pump 14 for circulating water is very small, and the power consumption as a whole is reduced. It is suppressed.

  As described above, with respect to one outdoor unit 1, the above-described effect is obtained by installing a set of auxiliary cooling devices 10 on the upstream side of the intake air of the outdoor unit 1. Here, when a plurality of, for example, four outdoor units 1 are arranged in the lateral direction, the configuration is as shown in FIG.

  FIG. 22 (a) is a plan view of the outdoor unit 1 in which four units are arranged in the horizontal direction, and FIG. 22 (b) is a view as seen from the upstream side of the intake air. Is visible. The horizontal and vertical dimensions of the outdoor unit 1 are determined according to the capacity of the outdoor unit 1, and the size of the water retaining material 30 is also set to the size of the outdoor unit 1 as shown in FIG. A combination of the two is used.

  Here, the water retaining material 30 is adjusted to the size of the outdoor unit 1 with the two water retaining materials 30a and 30b, and the cooling panel 40 is composed of the water retaining material 30 and the square frame 43 that supports the water retaining material 30. Composed. The size of the cooling panel 40 substantially corresponds to the size of one outdoor unit 1, and the cooling panels 40 are respectively disposed facing the outdoor units 1.

Thus, the state which has arrange | positioned the cooling panel 40 corresponding to the magnitude | size of the outdoor unit 1 in each outdoor unit 1 is shown in FIG. FIG. 23A shows a plan view, and FIG. 23B shows a front view. Water is supplied to each cooling panel 40 from the water supply pipe 15 via each branch part 35 and each branch pipe 33, and water drained from the cooling panel 40 passes through each branch pipe 34 and further passes through the drain pipe 12 to be water. Water is circulated to the recovery device 13.
In addition, what is shown in FIG. 23 has shown the piping of the water supply to the water retention material 30 of each cooling panel 40 at the time of arrange | positioning the four cooling panels 40 in the prior art example of the said patent document 1. As shown in FIG. is there.

  FIG. 24 shows an embodiment of the above-mentioned Patent Document 1. That is, instead of arranging one cooling panel 40 for one outdoor unit 1, the water retaining material 30 itself is arranged in parallel.

A plurality of water retaining materials 30 are arranged adjacent to a long support 60 that also serves as a drainage channel, and the support 60 is positioned slightly below the lower end of the outdoor unit 1 to provide a floor. It is provided by a support from the surface. Moreover, the length of the support stand 60 is formed a little longer than the length which added the length of the horizontal direction of the several outdoor unit 1. FIG.
Unlike the lower support base 60, the upper panel 61 disposed on the upper part of the water retaining material 30 is associated with each outdoor unit 1. Therefore, in the illustrated example, since four outdoor units 1 are arranged side by side, four upper panels 61 are used.

  The upper panel 61 is configured as shown in FIG. 25, FIG. 25A shows a cross-sectional view of the upper panel 61, and FIG. 25B is a plan view of a water supply plate 62 provided in the upper panel 61. Is shown. A large number of holes 63 are perforated along the longitudinal direction in the water supply plate 62, and water flowing in from the branch pipe 33 inserted from the upper part of the upper panel 61 falls on the water supply plate 62 and further from each hole 63. Water drops on the upper surface of the water retaining material 30. Then, water penetrates into the water retaining material 30 as described above, the water retaining material 30 becomes wet, and the sucked air is cooled.

  In the example shown in FIG. 24, the water retention material 30 having a rated size is used, and two water retention materials 30 are used for one outdoor unit 1. Therefore, when eight water retaining materials 30 are arranged adjacent to the four outdoor units 1, the ends of the water retaining materials 30 on both sides protrude from the outdoor unit 1. However, the end of the water retaining material 30 protruding from the outdoor unit 1 covers the entire condenser 3 of the outdoor unit 1, and the cooled air is sent to the condenser 3 so that the condenser 3 can be efficiently used. It can be cooled.

As shown in FIG. 26, the support base 60 has a substantially U-shaped cross section, has an upper surface opened, and the bottom surface is closed to form a drainage channel. On both sides of the support base 60, long or short bases 64 are disposed along the longitudinal direction of the support base 60, and the water retaining material 30 is disposed on the base 64. .
And the center part of the base 64 of both sides is made into the drainage channel 65 for draining (circulating) the water dripped from the water retention material 30. FIG.

  Further, as shown in FIG. 26, the upper panel 61 is disposed on the upper part of the water retaining material 30 disposed on the support base 60, and the water retaining material 30 is held by the upper and lower upper panels 61 and the support base 60. In addition, as shown in FIG.24 (b), the two water retention materials 30 are hold | maintained by the one upper panel 61. FIG. FIG. 24A shows a state where the upper panel 61 is removed.

Water was supplied from 33 to each water retaining material 30.

  In the case where there is one outdoor unit 1 and one water retaining material 30 is provided for this one outdoor unit 1, a valve is interposed in the water supply pipe 15 so that the entire water retaining material 30 gets wet. So that the valve can be adjusted manually.

  However, in the illustrated example, there are a plurality of water retaining materials 30 and four outdoor units 1 in the illustrated example. However, when the water retaining materials 30 are arranged corresponding to five or more outdoor units 1, the water supply pipe 15 The water pressure decreases as the length increases and reaches the end of the water supply pipe 15. Therefore, in the case shown in FIG. 24, the amount of water supplied to the left water retaining material 30 is smaller than the amount of water supplied to the right water retaining material 30.

Therefore, the water supply amount of each water retention material 30 is not uniform, the water retention material 30 on the end side of the water supply pipe 15 cannot be sufficiently wet, and the condenser 3 of the outdoor unit 1 is efficiently cooled. I can't.
Further, if a valve is interposed in the water supply pipe 15 on the water recovery device 13 side so that the water retention material 30 on the end side is sufficiently wetted, the water retention material 30 on the upstream side is supplied more than necessary and wasted. Water will flow.

FIG. 1 is an explanatory diagram for explaining the present invention, and corresponds to FIG. 24A in the case where four water retaining materials 30 are arranged in the lateral direction. In addition, since the water retaining material 30 itself is not the gist of the present invention, the number and size of the water retaining material 30 do not correspond to the conventional example in the drawings from FIG. 1 and FIG. The drawing shows a state in which 30 is provided.
In FIG. 1, the valve 44 may be interposed on the upstream side of the water supply pipe 15, or the valve 44 may not be interposed.

In FIG. 1, the branch pipes 33 branched from the respective branch portions 35 of the water supply pipe 15 are the branch pipes 33a, 33b, 33c, 33d from the upstream side, and the water retaining material 30 is also the water retaining material 30a, 30b, 30c, from the upstream side. 30d.
When the pump 14 is driven and water from the water recovery device 13 is supplied from the water supply pipe 15 to the branch pipes 33a, 33b, 33c, and 33d via the branch portion 35, the water in the branch pipes 33a, 33b, 33c, and 33d. As for the water pressure and water volume, the water pressure is lower and the water volume is lower as it goes downstream.

Therefore, the amount of water supplied to each of the water retaining materials 30a, 30b, 30c, and 30d supplied from each branch pipe 33a, 33b, 33c, and 33d is not evenly supplied, and the amount of water supplied to the water retaining material 30 is reduced toward the downstream side. Less.
Therefore, the amount of water supplied to each of the water retaining materials 30a, 30b, 30c, and 30d is not uniform, and the amount of water supplied decreases toward the downstream, so that the air passing through the water retaining material 30 cannot be efficiently cooled.

Therefore, FIG. 2 shows that the water retaining materials 30a, 30b, 30c and 30d can be evenly supplied with water. Valves 46 (46a, 46b, 46c, 46d) are interposed in the branch pipes 33a, 33b, 33c, 33d branched from the water supply pipe 15 via the branch portion 35, and the valves 46a, 46b, 46c, 46d are provided. Is provided with a manual knob 47 for adjusting the flow rate flowing in the branch pipes 33a, 33b, 33c, 33d.
Note that the branch portion 35 provided at the end of the water supply pipe 15 may not be provided, and a valve 46 may be interposed on the end side of the water supply pipe 15.

By adjusting the knob 47 of each valve 46a, 46b, 46c, 46d, the amount of water supplied to each water retaining material 30a, 30b, 30c, 30d can be adjusted to the minimum necessary. That is, the knob 47 is adjusted while observing the amount of water flowing through the water retaining material 30, and the knob 47 is adjusted so that the water retaining material 30 becomes wet and does not allow water to flow more than necessary.
Adjustment work by the knob 47 is performed for each of the water retaining materials 30a, 30b, 30c, and 30d.

The adjustment work of the knob 47 for adjusting the amount of water is not just turning the knob 47 but also the water retaining material 30 is sufficiently wet, and the operator visually checks whether water is flowing more than necessary. It is necessary to make adjustments.
Even when there are four outdoor units 1 as shown in the drawing, that is, when four water-retaining materials 30 are provided, adjusting the amount of water supplied to each water-retaining material 30 is a difficult task. In the case where a large number of outdoor units 1 are arranged, the work becomes even more difficult.

  By the way, the auxiliary cooling system for a condenser according to the present invention is designed to save energy in view of the recent power situation and the situation such as the rise in power price accompanying the rise in energy price. In particular, the auxiliary cooling system of the condenser is mainly intended for use in the summer, for example, frozen food, storage of refrigerated food, freezer for display, refrigerators are operated continuously for 24 hours, The condenser auxiliary cooling system also operates continuously for 24 hours.

Therefore, the power consumption of the pump 14 for water circulation, which is the only member that consumes power in the condenser auxiliary cooling system, is better. The required amount of water for the water retaining material 30 is the amount of water that covers the maximum amount of evaporation in summer when the amount of water evaporated from the water retaining material 30 is the largest. The pump 14 is required to have the capacity to satisfy this required amount of water.
As the capacity of the pump 14, it is sufficient if it can cover this maximum evaporation amount and supply water to each of the water retaining materials 30, and if the pump 14 has more capacity than that, the power consumption of the pump 14 increases and energy saving is achieved. It will be contrary.

In the auxiliary cooling system of the present condenser, the amount of water raised by one pump 14 is used after being divided into a plurality of branch pipes 33, so that each branch pipe 33a, 33b, 33c, 33d is used as shown in FIG. Even if the valves 46a, 46b, 46c, 46d are interposed, it is difficult to distribute (equalize) the water flowing through the branch pipes 33a, 33b, 33c, 33d.
In order to evenly distribute (divide water) a limited amount of water and to facilitate adjustment with the valve 46 for that purpose, the present inventor considered visualization of the amount of water flowing through the branch pipe 33. In addition, the structure shown in FIG. 3 is simple in structure or configuration and solves the above problems at low cost.

That is, as shown in FIG. 3, the amount of water flowing in the branch pipes 33a, 33b, 33c, and 33d is visualized downstream of the valves 46a, 46b, 46c, and 46d provided in the branch pipes 33a, 33b, 33c, and 33d. A visualization device 70 is provided.
FIG. 4 shows a front view of the visualization device 70, and FIG. 5 shows a plan view of the visualization device 70.

The visualization device 70 is made of a transparent plastic member having a cylindrical pipe shape, and is detachably attached to a chamber box 71 having an upper surface opened and a lower surface closed, and an opening on the upper surface of the chamber box 71. And a cap 72.
Circular holes (not shown) are opened on both sides of the chamber box 71, and the upstream branch pipe 33 and the downstream branch pipe 33 are connected to the holes on both sides, and the inside of the upstream branch pipe 33 is connected. Water flows into the chamber box 71 (visualization device 70), and further water in the chamber box 71 flows into the branch pipe 33 on the downstream side. An air escape hole 73 is formed in the upper portion of the chamber box 71.
The branch pipes 33a, 33b, 33c, and 33d have the same inner diameter, and the chamber boxes 71a to 71d have the same inner diameter and inner volume.

Next, an adjustment method in the case of flowing (distributing) water evenly to each water retaining material 30 will be described. First, as shown in FIGS. 3 and 6, the knob 47 of each valve 46a, 46b, 46c, 46d is rotated so that water flows, and then the pump 14 is driven.
When the pump 14 is driven, the water from the water recovery device 13 flows to the branch pipes 33a, 33b, 33c, and 33d via the water supply pipe 15 and the branch portion 35 as shown in FIG. In each branch pipe 33a, 33b, 33c, 33d, water flows to each water-retaining material 30a, 30b, 30c, 30d via the valves 46a, 46b, 46c, 46d and the visualization device 70 (chamber boxes 71a-71d).
In addition, the same thing is used for the magnitude | size and structure of each water retention material 30a, 30b, 30c, 30d.

While water is flowing through each of the water retaining materials 30a, 30b, 30c, and 30d, the water retaining material 30d is allowed to flow over the entire downstream water retaining material 30d, and the water retaining material 30d is moistened. The knob 47 of the valve 46d is adjusted so that it does not flow.
The water retaining material 30d is allowed to flow evenly and only a little water should flow, and the knob 47 of the valve 46d is adjusted in this state. The water level in the chamber box 71d at this time is L1. The water level in the chamber box 71 is located above the branch pipe 33 due to water pressure.

Next, the valve 46c corresponding to the water retention material 30c on the upstream side of the water retention material 30d is adjusted. The valve 46c is adjusted by adjusting the knob 47 of the valve 46c so that the water level in the chamber box 71c is the same as the water level L1 in the downstream chamber box 71d.
Further, the valve 46b corresponding to the water retaining material 30b on the upstream side of the water retaining material 30c is adjusted. The valve 46b is adjusted by adjusting the knob 47 of the valve 46b so that the water level in the chamber box 71b is the same as the water level L1 in the downstream chamber box 71d or the horizontal chamber box 71c.

  Similarly, the valve 46a corresponding to the water retaining material 30a on the upstream side of the water retaining material 30b is adjusted. The valve 46a is adjusted by adjusting the knob 47 of the valve 46b so that the water level in the chamber box 71a is the same as the water level L1 in the downstream chamber box 71d or the chamber boxes 71c and 71b.

  Here, each visualization device 70 (chamber boxes 71a to 71d) is arranged in each branch pipe 33a, 33b, 33c, 33d so that the height thereof is the same. Therefore, by adjusting the water level in the other chamber boxes 71a, 71b, 71c to L1 to the water level L1 in the chamber box 71d when the most downstream valve 46d has been adjusted, each water retaining material 30a, 30b, 30c. 30d, almost the same amount of water is distributed almost evenly.

That is, when a plurality of water retaining materials 30 are arranged and the amount of water supplied to each water retaining material 30 is evenly distributed, first, the amount of water is observed while supplying water to the most downstream water retaining material 30, and the water retaining material 30. The knob 47 of the valve 46 is adjusted so that the water amount becomes an appropriate minimum amount of water to be moistened.
In such a case, the water level in the chamber box 71 is stabilized at a position higher than the branch pipe 33. Thereafter, when adjusting the amount of water supplied to the water retaining material 30 upstream from the most downstream water retaining material 30, the water level in each chamber box 71 is set to be the same as the water level in the most downstream chamber box 71. It is only necessary to adjust the knob 47 of each valve 46 while looking at the water level.

In this way, the adjustment is made while first observing the amount of water supplied to the most downstream water retaining material 30, and thereafter, the knobs 47 of the other valves 46 are only adjusted to be the same as the water level in the chamber box 71. The adjustment of the water supply amount to the water retaining material 30 can be visualized, and the adjustment for evenly distributing the water amount to each water retaining material 30 becomes very easy.
In addition, since the visualization device 70 is constituted by a transparent plastic chamber box 71 as a pressure adjusting chamber into which water is once inserted, the visualization device 70 can be made very inexpensive. Further, the water supply amount of the water retaining material 30 can be evenly distributed by the transparent visualization device 70 and the water amount adjusting valve 46, and the structure for evenly distributing the water supply amount of the water retaining material 30 can be simplified. .

  In addition, since the amount of water supplied to the water retaining material 30 is minimized, even if a plurality of water retaining materials 30 are installed, the pump 14 having the capacity corresponding to the water retaining material 30 can be used, and the pump 14 with low power consumption can be used. it can. Thereby, it is possible to save energy in the entire auxiliary cooling system of the condenser.

Further, in the auxiliary cooling system of the condenser, since it is exposed to the outside in the middle of the water flow, dust and dust circulate, but this chamber is used to temporarily pass the circulating water into the chamber box 71. Floating in the box 71.
Therefore, it is possible to remove dust and dust in the chamber box 71 by removing the cap 72 that is detachably attached to the upper portion of the chamber box 71.

  As shown in FIG. 4, the left and right sides of the chamber box 71, that is, the height positions of the upstream and downstream branch pipes 33 are the same, but the downstream branch pipe 33 is positioned higher than the upstream branch pipe 33. By making it low, it is possible to make it difficult for dust and dirt that have entered the chamber box 71 to flow out to the downstream branch pipe 33. Therefore, the chamber box 71 can have a function like a filter, and the chamber box 71 can remove more dust and dust.

(Second Embodiment)
FIG. 7 shows a second embodiment of the visualization device 70 in which the water level in the chamber box 71 can be easily discriminated and the adjustment of other valves 46 is facilitated.
That is, a scale 75 is provided on the surface of the chamber box 71, and the water level in the chamber box 71 can be easily recognized by the scale 75.

If the water level in the chamber box 71 when the amount of water supplied to the water retaining material 30 is first adjusted is a position slightly lower than “5” on the scale, for example, as shown in FIG. When adjusting the water supply amount, when adjusting the other valve 46, the valve 46 is only adjusted so that the water level in the chamber box 71 is slightly lower than “5” on the scale 75.
For this reason, the numerical value of the scale 75 corresponding to the water level of the chamber box 71 is remembered, and only the other valve 46 is adjusted so that the water level in the chamber box 71 is the same as the numerical value. Adjustment to distribute the amount of water evenly can be made very easy.

(Third embodiment)
FIG. 8 shows a third embodiment of the visualization device 70. In the present embodiment, a floating body 77 is floated on the water surface in the chamber box 71. The floating body 77 is made of, for example, plastic and has a conspicuous color so that it can be easily seen. The floating body 77 is formed in a disc shape, and the outer diameter of the floating body 77 is slightly smaller than the inner diameter of the chamber box 71.
As the water surface in the chamber box 71 moves up and down, the floating body 77 also moves up and down, so that the operator can easily see the water level of the chamber box 71 by looking at the floating body 77.

When adjusting the water supply amount of the upstream water retention material 30 after adjusting the water supply amount of the most downstream water retention material 30, while looking at the height position of the floating body 77 of the adjusted chamber box 71 The knob 47 of the valve 46 is adjusted so that the height positions of the floating bodies 77 of the chamber box 71 are the same.
As described above, when the water supply amount of the water retaining material 30 is adjusted by the valve 46, the valve body 46 is adjusted by simply looking at the floating body 77 of the adjusted chamber box 71 and adjusted to the height position of the floating body 77. Thus, the water supply amount of the water retaining material 30 can be adjusted appropriately and easily.

  Note that the floating body 77 shown in FIG. 8 may be placed in the chamber box 71 provided with the scale 75 shown in FIG. In such a case, the height position of the floating body 77 can be easily seen. When adjusting the water supply amount of the water retaining material 30, if the value of the scale 75 is remembered, the water supply amount of the water retaining material 30 Adjustment can be performed smoothly.

  Further, since the floating body 77 is formed in a disc shape, the floating body 77 is stable in the cylindrical chamber box 71 and may be visually.

(Fourth embodiment)
FIG. 9 shows a fourth embodiment of the visualization device 70. In the present embodiment, the positions of the upstream and downstream branch pipes 33 connected to the chamber box 71 are shifted in the front-rear direction. As shown by the arrows in FIG. 9, since the front and rear positions of the branch pipe 33 are shifted, the fluid rotates in the chamber box 71, so that dust 78 having a high specific gravity, such as a fluid cyclone trainer, is collected at the center. It becomes easy to accumulate in the lower part in the chamber box 71. Further, the dust 79 having a low specific gravity floats on the water surface as shown in FIG.
Further, dust 78 and dust 79 are accumulated in the chamber box 71, and water can smoothly flow out to the downstream branch pipe 33.

  The dust 78 and dust 79 in the chamber box 71 can be easily removed by removing the cap 72. Therefore, even if impurities are mixed in the water circulating in the entire system, it can be removed by the chamber box 71, and as clean water as possible can be circulated. The removal of the dust 78 and dust 79 may be performed periodically, and since the chamber box 71 is transparent, the dust 78 and dust 79 in the chamber box 71 can be easily visually recognized and removed when a little is accumulated. You may do it.

FIG. 11 shows a case where the downstream branch pipe 33 is made lower than the upstream branch pipe 33, and the water flow in the chamber box 71 is easily stirred. Thereby, it is possible to easily separate the dust 78 having a high specific gravity and the dust 79 having a low specific gravity.
Further, the configuration shown in FIG. 11 may be combined with the configuration shown in FIG.

(Fifth embodiment)
A fifth embodiment is shown in FIGS. In the previous embodiment, the visualization device 70 has a cylindrical shape, but in the present embodiment, the chamber box 71 is configured by a rectangular (rectangular, square, etc.) container. The cap 72 is also formed in a square shape in accordance with the shape of the chamber box 71.

  The square chamber box 71 has a larger area than the cylindrical one of the previous embodiment, and therefore the volume itself becomes large, so that the water level in the chamber box 71 is constant or stable. Thereby, it becomes easy to adjust the water supply amount of the water retaining material 30.

  Also in this embodiment, a scale 75 as shown in FIG. 7 may be formed on the surface of the chamber box 71, and the floating body 77 may be floated. Further, the height position of the upstream and downstream branch pipes 33 may be changed as shown in FIG. 11, or may be shifted in the front-rear direction as shown in FIG. That is, you may combine various structures of previous embodiment.

In each of the above embodiments, only the chamber box 71 is a transparent member, but the water supply pipe 15 and each branch pipe 33 may be formed of a transparent member.
Further, the size and material of the visualization device 70 are not particularly limited, and the shape is not particularly limited to a circle or a square as long as the area in the horizontal level in the chamber box 71 is constant.

  Furthermore, although the said embodiment demonstrated the case where the number of the outdoor unit 1 and the water retention material 30 arrange | positioned in the applicable outdoor unit 1 was four, if it is two or more, the visualization apparatus 70 will be provided and water retention will be carried out. Adjustment of the water supply amount of the material 30 can be facilitated.
