[0003]

However, there is a problem that a large amount of power is consumed for supplying the cool air by operating the refrigerator. An object of the present invention is to provide a cool air supply mechanism that consumes less power.

[0004]

According to the present invention, there is provided a cooling air supply mechanism for cooling, comprising: a blower, a water tank in which water is stored and sealed, a pipe arranged in the water of the water tank, and a water tank connected to the water tank. Duct. The underwater pipe has one end connected to the blower and the other end opened to a space above the water surface of the water tank, and the duct communicates with the space above the water surface.

Another cold air supply mechanism according to the present invention has a blower, a water tank for storing water, one end connected to the blower, and another open end, and is provided between these two ends. An opening including a duct having at least one passage extending vertically and watering means for spraying water into each passage of the duct, wherein the passage is received in the water tank and opened in the water of the water tank. Having.

[0006] Still another cold air supply mechanism according to the present invention is:
The blower, the water tank in which water is stored and sealed, the pipe disposed in the water of the water tank, a duct having the passage extending vertically, and water for sprinkling into the passage. Combined with watering means. In this combination, one end of the duct is open to the space above the water tank.

[0007] The water tank may be provided with a partition for partitioning a space above the water tank. The partition defines an air passage between the other end of the pipe in water and one end of the duct opening into the space above the water tank in cooperation with the water tank and the water surface.

Preferably, there is provided a watering means for watering the space above the water surface of the water tank. Further, it is desirable to provide a net member that crosses the passage. Preferably, the pipe has a shape extending in a meandering manner in water.

Further, another cool air supply mechanism according to the present invention may further include, in addition to the blower, the sealed or unsealed water tank, and the pipe in the water tank, the cool air supply mechanism may be connected to the pipe and provided in a space above the water surface of the water tank. A passage member cooperating with the water surface to define an enclosed space; a water pipe having at least one hole rotatably disposed in the passage member around an axis thereof; and a water pipe fixed to the water pipe. A porous member surrounding the water pipe;
A duct connected to the passage member and having or not having the passage portion and watering means. The arrangement of the pipe in the water layer may be omitted, and the passage member may be connected to the blower.

[0010]

According to the present invention, when air is sent to a pipe in a water tank by operating a blower, the air passes through the pipe, reaches the space above the water tank from the pipe, and connects the space above the water tank. Then, it flows into the duct from one end thereof. The air passing through the tube in the water is deprived of heat by the water around the tube through the tube, and its temperature decreases. Next, the air discharged from the other end of the pipe into the upper space vaporizes water vapor near the water surface while flowing through the upper space, and loses heat. This further reduces the temperature of the air. As a result, cool air for cooling is obtained, and the cool air can be led to the room via the duct. Therefore, the cool air can be obtained by the operation of the blower, and the power consumption required for the operation of the blower is significantly smaller than the power consumption required for the operation of the conventional refrigerator.

By meandering the underwater pipe, the passage time of the air passing through the pipe can be increased, and the temperature of the air can be further reduced. In addition, by partitioning the upper space of the water tank and forming a passage for the air flowing through the upper space, the opportunity and time of contact of the air with the water surface are increased, and thereby, The heat of vaporization that is deprived can be increased and the air can be further cooled.

Further, if watering means for watering the space above the water tank is provided, the chance of contact between the air and water moving in the space above is further increased, and the water is vaporized due to the contact. By applying heat, the air can be further cooled. Further, if at least one mesh member is provided across the passage, water sprayed from the watering means adheres to the mesh member and closes the mesh. The pressured air moving through the passage passes through the mesh member and breaks through a film of water covering the mesh.
Due to the contact with water at this time, the temperature of the air is further reduced.

According to another cool air supply mechanism of the present invention, when air is sent from one end to the duct by the operation of the blower, the air passes through the passage between both ends of the duct. During this time, when the water sprinkling means is operated and water is sprinkled into each passage portion, the air comes into contact with the water sprinkling and deprives the heat of vaporization,
Cooled. Since the passage portion extends in the vertical direction and the opening at the lower end is in the water in the water tank, the air is guided through the duct toward the other open end without leaking from the passage portion. . Further, the water spray falls vertically in each passage portion toward the water surface of the water tank, and changes into a large number of water droplets or droplets during this time, so that the air takes more heat of vaporization. The power consumption required for operating the watering means is also smaller than the operation of the refrigerator. The duct may be supported on a building having a room to receive a supply of cool air.

Further, in another cool air supply mechanism in which a passage member that defines a closed space in cooperation with a water surface is disposed in the space above the water tank, the air is supplied from the pipe or the blower through the passage member. To the duct. While the air passes through the passage member, a water pipe arranged in the passage member is rotated around an axis of the passage member, and water is ejected from the hole of the water pipe into the passage member. it can. The ejected water is subdivided into smaller water droplets as it passes through the porous member surrounding the water pipe under centrifugal force acting on the water, and the air touches the small water droplets during its flow, The heat is deprived and the temperature drops further. The water falls on the water surface after coming into contact with the air. The power consumption required for rotationally driving the water pipe is also smaller than the operation of the refrigerator.

[0015] Further, regarding the path of the air sent by the blower, the path is defined as the pipe passed through the water in the water tank, the space above the water tank and the passage of the duct, or A further cooling effect can be obtained by using the passage member passing through the space above the water tank and the passage portion of the duct.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, cooling of a multi-storey building 10, such as an office building, and more particularly,
A mechanism 14 for supplying cool air for cooling each room 12 in the building 10 is shown.

The building 10 has a receiving space 16 for the cool air and a plurality of holes 1 communicating with the space and each room 12.
8 are provided. These spaces 16 and holes 18
Will be described later. In the drawing, white arrows indicate the flow direction of the cool air, and black arrows indicate the flow direction of the warm air sent using the flow space of the cool air.

The cool air supply mechanism 14 includes a blower 20 such as a blower and a plurality of water tanks 22 storing water 21 (FIG. 2).
) And a pipe 24 arranged in each water tank 22 and extending underwater.
And a duct 26 connected to each water tank 22.

The blower 20 is located outside the water tank 22 and is connected to one end 28 of the pipe 24. By operating the blower 20, outside air, which is air outside the building 10, can be sent into the pipe 24. During the flow (the direction of the flow is indicated by an arrow 29), the air sent into the pipe 24 exchanges heat through the pipe wall, that is, the heat of the air is transferred to the water 21 through the pipe 24, This allows
The air is cooled.

The illustrated water tank 22 in which the pipes 24 are arranged is provided as a part of the building 10 on the basement of the building. Since the basement has a smaller temperature change than the ground surface, the temperature change of the water 21 in the water tank 22 is small, which is advantageous for the heat exchange for the outside air. However, if necessary, the water tank may be
Can be installed underground or above the ground, and the number of the water tanks can be set to one or three or more.

The water tank 22 is hermetically sealed. The water tank 22 has a top wall (floor slab on the first floor) 30 defining the water tank 22 and a space 34 defined by a side wall and a water surface 32.

The underwater pipe 24 is open at the other end 36 to a space 34 above the water surface 32 in the water tank 22.

The tube 24 in the water tank 22 is preferably made of a material having high thermal conductivity which is advantageous for the heat exchange, for example, a metal tube or a plastic tube such as vinyl chloride. The pipe 24 can be installed so as to extend linearly or curvedly in the water. However, the pipe 24 extends in a meandering manner as shown in the illustrated example (see FIG. 2), so that the inside of the pipe 24 can be extended. The indirect contact area and contact time between the flowing air and the water 21 can be increased, and the cooling of the air can be further promoted.

After passing through the pipe 24, the air is discharged from the other end 36 into the upper space 34 of the water tank, and further flows through the upper space 34 toward one end 37 of the duct 26.
While flowing through the upper space 34, the air comes into contact with water vapor near the water surface 32 that defines the upper space, thereby removing heat of vaporization. As a result, the temperature of the air further decreases before reaching the one end 37 of the duct 26.

Preferably, a partition 38 for partitioning the space 34 above the water tank 22 is provided. A partition 38 defines a meandering passage between the open end 36 of the tube and one end 37 of the duct 26 for the air discharged from the open end 36 of the tube.

The illustrated partition 38 is composed of a plurality of partition plates 42 extending alternately from one side of a pair of side walls 40 that define the water tank 22 to the other, and each partition plate 42 has an upper edge portion. It is connected to the top wall 30 of the water tank 22, and its lower edge is submerged below the water surface 32.

According to this, the air discharged from the other end 36 of the pipe 24 flows through the passage defined by the partition plate 42 by the arrow 4.
It flows meandering as shown at 4. The air flowing along the passage defined by the partition 38 has more opportunities to contact the water surface and a longer contact time than in a case where such a passage is not provided. For this reason, the cooling degree of the air is further increased.

More preferably, a watering means 46 for watering the upper space 34 is provided. The illustrated watering means 46 has a water pipe 48, a plurality of nozzles 50 connected to the water pipe, and a pump (not shown) provided in the water pipe 48, and the nozzle 50 is located above the water surface 32. It is open to the passage defined by the partition 38. By the operation of the pump, the water 21 in the water tank is pumped to the water pipe 48,
Each nozzle 50 can be ejected into the passage.
The air passing through the passage comes into contact with water droplets jetted from each nozzle 50, further deprives the heat of vaporization, and is further cooled. The water ejected from the nozzle 50 is preferably in the form of a mist in order to increase the efficiency of heat exchange between air and water.

Further, it is preferable that at least one, more preferably, a plurality of wire members 51 such as a wire mesh are arranged in the passage defined by the partition 38 at intervals from each other in the direction in which the passage extends. I do.

The mesh member 51 is provided with two partition plates 4 facing each other.
2 and the top wall 30 of the aquarium. The top end and the bottom end of the mesh member 51 are respectively connected to the top wall 30 so that air flowing through the passage always passes through the mesh of the mesh member 51.
It is desirable to be in contact with and immersed in water.

The mesh member 51 traversing the passage is provided with a nozzle 5
One or more meshes are covered with a film of water due to the water or mist spraying from zero. The air, which is compressed air flowing through the passage, breaks through the water film when passing through the mesh through the mesh member 51. At this time, the water film bursts,
It scatters in the flowing air. In contact with these scattered water droplets or mist droplets, the temperature of the flowing air further decreases.

The air passing through the passage defined by the partition 38 in the upper space 34 and passing through the net member 51 passes through the duct 2 which opens to the upper space at the end of the passage.
6 flows into the duct from one end 37.

The illustrated duct 26 is supported by the building 10. Alternatively, it can be supported independently of building 10 using a suitable support member (not shown). The duct 26 has at least one (three in the illustrated example) passage portions 52 extending vertically at both ends 37 and 57 thereof,
These passages 52 are connected in series.

Each passage 52 has a lower end extending downward through the water tank through the top wall 30 of the water tank 22. The lower end of the passage 52 has an opening 54 that extends into the water 21 and opens in the water. In the illustrated example, one end (lower end) 37 of the duct is

The water 21 in the inside is jetted through the water pipe 60 and the nozzles 62 into the passages 52 and the pipes 53. Pipe section 5
The air sequentially passing through 3 and each passage portion 52 comes into contact with water jetted from each nozzle 62 and is further cooled.

The water jetted from the nozzle 62 is supplied to the pipeline 5
3 and each of the passages 52 are lowered vertically, and are passed through the lower end 37 of the conduit 53 and the lower end 54 of each of the passages 52.
Return to 2. After the air has passed through the last passage 52,
The cooling air is discharged from a pipe member 57 that communicates with the last passage 52 that defines the other open end of the duct 26.

The cool air discharged from the open end 57 of the duct is divided into a vertical duct 64 extending vertically and a vertical duct 64.
To the room 12 of the building via a horizontal duct 66 connected to the vertical duct and extending horizontally at each level. More specifically, it is guided from the horizontal duct 66 to each room 12 on the lower floor via the space 16 below the floor on the upper floor of the building 10 and the hole 18 communicating with the space.

The horizontal duct 66 is supported on the wall of the building 10. The horizontal duct 66 is provided on a wall of the building 10, a hole 67 penetrating the wall, a ceiling slab 68 defining a ceiling of the room 12, and a room disposed on the ceiling slab 68 and supported by the ceiling slab. Plural flooring materials 7 defining 12 floor surfaces
0 communicates with the space 16 composed of a plurality of passages 72 defined by each of the zeros.

Each passage 72 has a terminal end in the direction of extension,
That is, it communicates with each hole 74 provided on the opposite wall defining the chamber 12. Each hole 74 communicates with another lateral duct 76 supported on the wall surface. Further, the horizontal duct 76
Communicates with another vertical duct 78, which is connected to the blower 2
Connected to 0.

Therefore, the cold air received in the passage 72 under the flooring 70 is partially (indicated by an arrow 73).
Flows into the chamber 12 through the hole 18 and is used for cooling, and another part (indicated by an arrow 75) is provided with another horizontal duct 76.

And a cylindrical member 86 fitted in a hole 84 vertically passing through a decorative plate 82 arranged in parallel with the ceiling slab 68. However, for the room 12 on the top floor, the space 16 is composed of a duct 90 arranged in a space defined by the ceiling slab 68 and the decorative board 82 of the chamber 12 and connected to the horizontal duct 66. Hole 1 connected to
The cold air is supplied to the chamber 12 via 8.

In the illustrated example, dampers 92 and 94 and a conduit 96 are arranged to use the cool air passage as a warm air passage for heating during the winter season when the cool air is not supplied.

One damper 92 is arranged inside the pipe member 57 that defines the open other end of the duct 26, and can open and close the pipe member. Also, the other damper 94 is
A conduit 96 is arranged in the conduit for opening and closing.

The conduit 96 is connected to an air conditioner (not shown) including the blower 20 and the vertical duct 64. When the cool air is supplied, one damper 92 is opened and the other damper 94 is closed, and when the warm air is supplied, one damper 92 is closed and the other damper 94 is opened. It is.

The warm air is sent in the opposite direction to the cold air. That is, warm air is introduced into the space 16 from the air conditioner via the other vertical duct 78 and the horizontal duct 76, and a part of the warm air flows from a hole (not shown) provided in the floor material 70 to the room 1.
2 or the floor material 70 is heated. Thereby, the heating of the room 12 is performed. Another part of the warm air and the warm air after flowing through the space 16 are returned to the air conditioner via one of the horizontal duct 66, the vertical duct 64, and the conduit 96. In this case, the opening of the cylindrical member 86, which is a cool air outlet, is closed with a lid (not shown) prepared in advance.

In the illustrated example relating to cooling, a wall 98 is provided to shield the duct 26 from direct sunlight.

Further, as the cool air supply mechanism, instead of the illustrated example in which the pipe 24 and the duct 26 are combined, these are separated from each other, that is, the blower 20
A water tank 22 in which water 21 is stored and sealed; a pipe 24 arranged in the water tank 22; and another end having one end opening to the upper space 34 of the water tank and the other end communicating with the vertical duct 64. A duct (not shown), or a blower 20 and a water tank 22 in which water 21 is stored.
, The duct 26, and the sprinkler device 58.

However, in the latter cool air supply mechanism having no pipe 24, one end 37 of the duct 26 is connected to the blower 20. Further, since the upper space 34 that defines the passage is not provided in the water tank 22, the water tank 22 does not need to be sealed. In the former cool air supply mechanism including the pipe 24, as shown in the illustrated example, the upper space 3 of the water tank 22 is provided.
4, a partition 38 can be provided, and further, a water sprinkling device 46 can be provided.

Next, as shown in FIGS. 4 and 5, a partition 38 as shown in FIG.
Instead of providing the watering device 46, the net member 51, and the like, a passage member 100 can be provided.

As shown in FIG. 6, the passage member 100 is opposed to the tube 102 at a distance from the tube 102 and fixed to the tube 102 and extending a part of the tube in the direction of extension thereof. It has a pair of side plates 104.

The pipe body 102 is suspended from the top wall 30 of the water tank 22 via a plurality of pairs of brackets 106 which are arranged at intervals in the direction of extension thereof and are fixed thereto. Thereby, the pipe body 102 is located above the water surface 32, the pair of side plates 104 hang down from the pipe body 102, and a part of the lower side of the both side plates 104 is submerged in the water 21. In addition, the pipe body 102 has, in a part thereof, a single slit 108 extending in the extension direction thereof, and the slit faces the water surface 32. Instead of the single slit 108, for example, the tube 10
A plurality of holes (not shown) may be provided at intervals from each other in the direction of extension of the two.

Thus, the pipe 10 of the passage member 100
2. The slits 108 and both side plates 104 of the tube body cooperate with the water 21 or the water surface 32 to form a space 3 above the water surface 32.
4 defines a closed space 110.

The passage member 100 is provided at one end 1 of the tube 102.
12 and the other end 36 of the tube 24,
The other end 114 of the second and the one end 37 of the duct 26 are connected to the pipe 24 and the duct 26. Therefore, the air after passing through the pipe 24 is supplied to the passage member 100.
Flows into the duct 26 through the closed space 110 (the flow direction of the air is indicated by reference numeral 116). Here, as described above, one end 28 of the pipe 24 is connected to the blower 20 and the duct 26 is connected to at least one passage 5.
2 and watering means 58 disposed in the passage portion.
However, as for the duct 26, it may be a simple ventilation pipe without the passage portion 52 and the watering means 58.

The sealed space 110 is connected to the other end 36 of the tube 24.
And one end 37 of the duct 26 may extend linearly or curvedly, but preferably extend in a meandering manner as in the example shown. In the illustrated example, each passage member 100 in each of the water tanks 22 extending in a meandering manner has four portions 117 extending in parallel with each other,
Each parallel portion 117 of both passage members 100 is on a common straight line. Due to the meandering, the enclosed space 1 with a longer extension distance
As a result, the flow distance and the flow time of the air in the closed space 110 can be increased, and the temperature of the air can be further reduced.

The two passage members 100 further have at least one water pipe 118, in the example shown, four common water pipes 118. Each common water pipe 118 extends axially through and penetrates both passage members 100, and more specifically, both parallel portions 117 extending along the common straight line of both pipes 102. . The water pipes can be arranged for each parallel portion 117 without using a common water pipe 118 instead of the illustrated example.

Each common water pipe 118 is rotatably mounted at one end thereof to one of the other three side walls 120 defining the water tanks 22, and the other end is provided at the other two ends. The common water pipe 118 penetrates the side wall 120 and is rotatably supported by the side wall, and is further connected to a rotary drive source including a motor, a reduction mechanism, and the like for driving each common water pipe 118 to rotate around its axis. The rotation drive source is housed in a casing 122.

Each common water pipe 118 is rotatably and air-tightly and liquid-tightly rotatable at each parallel portion 117 via a bearing means 124 so that the air does not leak from the closed space 110. It is supported on the body 102.
Each common water pipe 118 is connected to the water pipe 1 via a bearing (not shown) that supports the water pipe even on the side wall 120 near the casing 122 that houses the rotary drive source.
Liquid tightness between 18 and side wall 120 is ensured.

In the casing 122, pump means (not shown) for supplying water to each common water pipe 118 is provided.
Is arranged. The pump means is connected to a pipe 125 extending through the side wall 120 of the water tank 22;
The water 21 in the water tank 22 can be supplied into each water pipe 118 by the operation of the pump means.

Each water pipe 118 has at least one hole 126 opened in each pipe body 102. In the illustrated example, a number of holes 126 are provided at intervals in the circumferential direction of each water pipe 118 and at intervals in the axial direction.

Each water pipe 1 in each pipe 102
The porous member 128 surrounding the periphery of each water pipe 11
8 is fixed. The porous member 128 is, for example, a chip made of a metal such as stainless steel, copper, or aluminum,
One or a plurality of wires made of metal such as stainless steel, copper, aluminum, and plastic are intertwined with each other and are formed in a tubular shape, and are fixed to each water pipe 118 and are generally cross-shaped in the radial direction. Are held around each water pipe 118 via a fixing member 30 extending to the bottom. The porous member 128 has an outer peripheral surface close to the inner wall of the pipe 102 so as not to hinder the rotation of the water pipe 118 and to almost fill the space between the water pipe 118 and the pipe 102. Is desirable. Further, the porous member 128 may extend continuously or intermittently along the water pipe 118.

In the cool air supply mechanism shown in FIGS. 4 to 6, while the air circulates in the closed space 110 of the passage member 100, the rotation driving means is operated to connect each common water pipe 118 to the same. It is rotated about an axis and the pump means is operated to supply water into each common drain 118.

The water supplied into each of the water pipes 118 is jetted through the holes 126 of the water pipes 118 to the outside, that is, into the porous member 128, and is further centrifuged by a rotational motion about the axis of each water pipe 118. It moves through the porous member 128 under force. During this movement, the water is divided into a number of small droplets, or the pores of the porous member 128 are closed.

Therefore, the air flows into the closed space 110.
(The direction of the flow is indicated by an arrow 132), a part of which passes through the porous member 128, and at this time, it contacts the large number of water droplets and breaks a water film blocking the eyes of the porous member 128. , To make it a finer mist. The air that touches the water droplets and flows by touching the fog droplets is deprived of heat by these and is cooled. Further, when the porous member 128 is made of one or more metal wires, the metal wires are also cooled by touching water, so that the air touches the metal wires. Is also cooled. Further, a part of the air flows in contact with the water surface 32 and is thereby cooled.

For cooling the air, it is desirable that the size of the water droplet is small, and it is desirable that the rotation speed of the water pipe 118 be high. This is because the power consumption of the rotary drive source is large. It can be determined in consideration of the size. Further, the amount of water flowing through the water pipe 118 can be arbitrarily determined.

As a cool air supply mechanism, one end 112 and the other end 114 of the pipe body 102 of the passage member 100 can be connected to the blower 20 without disposing the pipe 24 in the water 21.
Duct 26 without passage 52 and watering means 58
Or the other end 1 of the tube 102
14 may be connected to the duct 26 having the passage 52 provided with the watering means 58.

The separate cool air supply mechanism and the combined cool air supply mechanism shown in FIG.
Can be selectively applied in consideration of the size of the building 10, the scale of the building 10, and the like.
