Description

  The present invention relates to a blower unit that blows conditioned air or clean air into a room.

  As an example of an air conditioner that performs indoor heating / dehumidification, dehumidification, humidification, and air purification, a direct-floor-floor type air conditioner formed from an equipment storage box in which an air conditioner is stored and a blower unit installed at the top of the box There is. In the direct blowing floor type air conditioner, conditioned air and clean air supplied from the air conditioner are discharged substantially horizontally from the blower outlet of the blower unit toward the room. The indoor air flows into the apparatus from an inlet formed in the lower part of the air conditioner, becomes air-conditioned air by the air conditioner, and is discharged from the blower unit into the room again. In such a direct-bed floor type air conditioner, the conditioned air or clean air released from the blower outlet of the blower unit collides with the manufacturing equipment or office equipment installed in the room, and the flow of air in the room is blocked by these equipment.

  However, the vertical flow type air conditioning system requires duct work in the ceiling, ceiling finishing work, heat insulation work, and the like, so that the installation cost is high and the apparatus cannot be installed inexpensively. In addition, since the vertical flow type air conditioning system requires a lot of work for installation, it is difficult to shorten the installation period. Furthermore, the outlet and the inlet cannot be easily moved, and the arrangement of the outlet cannot be easily changed according to the change in the indoor layout, so that the degree of freedom in changing the indoor layout is small.

  An object of the present invention is to provide a blower unit that can evenly distribute conditioned air and clean air throughout the room. Another object of the present invention is to provide a blower unit in which the apparatus can be installed inexpensively and in a short period of time, and the arrangement can be easily changed according to a change in indoor layout.

  The premise of the present invention to solve the above problems is that an air inlet, an air outlet that faces the room and is arranged above the room, and an air flow path that extends from the inlet toward the outlet. And a blower unit that discharges conditioned air and clean air from the outlet into the room.

  A feature of the present invention based on the premise is that the blower unit has a wind speed adjusting mechanism that gradually increases the wind speed of the conditioned air or the clean air from the lower side to the upper side of the air outlet.

  As an example of the present invention, the wind speed adjusting mechanism is formed from a partition plate arranged in the air flow path. In this blower unit, the air flow path is divided into first to nth flow paths arranged from above to below by the partition plate, and the area of the inlet portion of the conditioned air or clean air in the first to nth flow paths is The flow rate of the conditioned air and the clean air flowing into the first to nth channels increases in order from the nth channel to the first channel, and increases in order from the nth channel to the first channel. Yes.

  As another example of the present invention, the wind speed adjusting mechanism is formed of a partition plate disposed in the air flow path and a damper. In this blower unit, the air flow path is divided into first to nth flow paths arranged from above to below by the partition plate, and dampers are installed in the first to nth flow paths. The opening degree of the blades of the damper is adjusted so that the flow rates of the conditioned air and the clean air passing through the path increase in order from the nth flow path toward the first flow path.

  As another example of the present invention, the wind speed adjusting mechanism includes a partition plate disposed in the air flow path, and a plurality of adjustment plates having a plurality of air circulation holes and capable of adjusting the flow rate of conditioned air and clean air. And is formed from. In this blower unit, the air flow path is divided into first to nth flow paths arranged from above to below by the partition plate, and the adjustment plates are individually installed in the first to nth flow paths. The adjustment plate installed in the flow path is formed in the adjustment plate so that the opening area of the air circulation hole is the smallest and the opening area of the air circulation hole of the adjustment plate installed in the first flow path is the largest. The opening area of the air circulation holes increases in order from the nth channel toward the first channel.

  As another example of the present invention, the wind speed adjusting mechanism is formed of an adjusting plate having a plurality of air circulation holes and capable of adjusting the flow rate of conditioned air or clean air. In this blower unit, the adjustment plate is installed in the vicinity of the air outlet in the air flow path, and the opening area of the air circulation hole formed in the adjustment plate gradually increases from the lower side to the upper side of the air outlet.

  As another example of the present invention, at least one of an air filter, a heat exchanger, and a blower is installed in the air flow path.

  According to the blower unit of the present invention, since the wind speed adjusting mechanism that gradually increases the wind speed of the conditioned air or the clean air from the lower side to the upper side of the air outlet, the air having the fastest wind speed is released from above the air outlet. The air can be sent far away in the room, and the air with the slowest wind speed can be sent from the lower part of the outlet to the room in the vicinity of the unit. The air can be sent to an intermediate position in the room between a distance in the room and the vicinity of the unit by releasing air at a wind speed of a certain level. In the blower unit, the conditioned air and clean air with the fastest wind speed reach the back of the equipment over the manufacturing equipment and office equipment with high height dimensions, and the conditioned air and clean air with the medium wind speed have the height dimensions. Since it reaches the back side of the equipment over the low manufacturing equipment and office equipment, the equipment does not block the flow of air in the room, and the air can be spread evenly throughout the room. Stagnation can be prevented. This blower unit does not require installation in the ceiling duct work, ceiling finishing work, heat insulation work, etc., so the unit can be installed at a low price, and it can be moved freely. The arrangement can be easily changed according to the indoor layout change.

  The partition plate installed in the air flow path forms a wind speed adjusting mechanism, and the area of the intake portion of the conditioned air and the clean air in the first to nth flow paths divided by the partition plate is the first flow from the nth flow path. Since the flow rate of the conditioned air and the clean air flowing into the first to nth flow paths increases in order from the nth flow path to the first flow path, the blower unit that becomes larger in order toward the road is located above the outlet. The air with the fastest wind speed is discharged into the room, the air with the slowest wind speed is discharged into the room from below the blower outlet, and the air with the medium wind speed is discharged into the room from the center in the vertical direction of the blower outlet. The blower unit can send air from the upper side of the blower outlet to the far room, and can send air from the lower part of the blower outlet to the room in the vicinity of the unit. Air can be sent to an intermediate position in the room between the vicinity of the unit. In this blower unit, the conditioned air and clean air with the fastest wind speed reach the back of the equipment over the manufacturing equipment and office equipment with high height, and the air conditioned air and clean air with the medium wind speed are the height. Because it reaches the back side of the equipment over the low production facilities and office equipment, the air flow in the room is not blocked by these equipment, and the air can be distributed evenly throughout the room. Occurrence of stagnation can be prevented.

  A wind speed adjusting mechanism is formed from the partition plate and the damper installed in the air flow path, and the flow rates of the conditioned air and the clean air passing through the first to nth flow paths are directed from the nth flow path toward the first flow path. The blower unit, in which the opening of the damper blades is adjusted so as to increase in order, discharges the air with the fastest wind speed from above the blower outlet into the room and the air with the slowest wind speed from below the blower outlet into the room. At the same time, air having an intermediate wind speed is discharged from the center in the vertical direction of the air outlet into the room. The blower unit can send air from the upper side of the blower outlet to the far room, and can send air from the lower part of the blower outlet to the room in the vicinity of the unit. Air can be sent to an intermediate position in the room between the vicinity of the unit. In this blower unit, the conditioned air and clean air with the fastest wind speed reach the back of the equipment over the manufacturing equipment and office equipment with high height, and the air conditioned air and clean air with the medium wind speed are the height. Because it reaches the back side of the equipment over the low production facilities and office equipment, the air flow in the room is not blocked by these equipment, and the air can be distributed evenly throughout the room. Occurrence of stagnation can be prevented.

  A wind speed adjustment mechanism is formed from the partition plate and the plurality of adjustment plates installed in the air flow path, and the opening area of the air circulation holes formed in the adjustment plates is sequentially from the nth flow path toward the first flow path. Since the air resistance in the first to nth flow passages decreases in order from the nth flow passage toward the first flow passage, the air blowing unit that is increasing is conditioned air or clean air with the fastest wind speed from above the blowout port. Is discharged into the room, and the conditioned air or clean air with the slowest wind speed is released into the room from below the outlet, and the conditioned air or clean air with a medium wind speed is released into the room from the center in the vertical direction of the outlet. The The blower unit can send air from the upper side of the blower outlet to the far room, and can send air from the lower part of the blower outlet to the room in the vicinity of the unit. Air can be sent to an intermediate position in the room between the vicinity of the unit. In this blower unit, the conditioned air and clean air with the fastest wind speed reach the back of the equipment over the manufacturing equipment and office equipment with high height, and the air conditioned air and clean air with the medium wind speed are the height. Because it reaches the back side of the equipment over the low production facilities and office equipment, the air flow in the room is not blocked by these equipment, and the air can be distributed evenly throughout the room. Occurrence of stagnation can be prevented.

  The adjusting unit installed in the vicinity of the air outlet in the air flow path forms a wind speed adjusting mechanism, and the opening area of the air circulation hole formed in the adjusting plate gradually increases from the lower side to the upper side of the air outlet. Since the air resistance in the first to nth flow paths gradually decreases from the nth flow path toward the first flow path, the conditioned air or clean air with the fastest wind speed is released into the room from above the outlet. Air-conditioned air and clean air having the slowest wind speed are released into the room from below the blower outlet, and air-conditioned air and clean air having an intermediate wind speed are released into the room from the center in the vertical direction of the blower outlet. The blower unit can send air from the upper side of the blower outlet to the far room, and can send air from the lower part of the blower outlet to the room in the vicinity of the unit. Air can be sent to an intermediate position in the room between the vicinity of the unit. In this blower unit, the conditioned air and clean air with the fastest wind speed reach the back of the equipment over the manufacturing equipment and office equipment with high height, and the air conditioned air and clean air with the medium wind speed are the height. Because it reaches the back side of the equipment over the low production facilities and office equipment, the air flow in the room is not blocked by these equipment, and the air can be distributed evenly throughout the room. Occurrence of stagnation can be prevented.

  A blower unit in which at least one of an air filter, a heat exchanger, and a blower is installed in the air flow path can be used without a separate air conditioner, air purifier, or blower. Cold air can be made, air can be purified, and air can be blown. The blower unit discharges conditioned air and clean air with the fastest wind speed from above the outlet into the room, and releases conditioned air and clean air with the slowest wind speed into the room from below the outlet and Air-conditioned air or clean air with a medium wind speed from the center in the direction is released into the room.

In FIG. 3, the flow of conditioned air or clean air is indicated by arrows. In FIG. 4, air is continuously supplied from the unit 14 </ b> A to the chamber 11, and the temperature distribution in the chamber 11 is schematically shown by an isotherm X.

  The direct-floor floor type air conditioner 10 is used for cooling and heating the room 11, dehumidification, humidification, and air purification. The room 11 in which the air conditioner 10 is used is not particularly limited, and can be used in any room such as an office room, a machine room, a factory, and a clean room. The air conditioner 10 is formed of a device storage box 12 that stores an air conditioner (not shown) and a blower unit 14 </ b> A installed on the top 13 of the device storage box 12. The device storage box 12 and the blower unit 14 </ b> A are connected via a duct 15. As shown in FIG. 2, two air conditioners 10 are installed along one wall 16 and the other wall 17. The air conditioners 10 are placed on the floor so as to face each other in the front-rear direction. The number of air conditioners 10 is not particularly limited, and the number can be determined as appropriate depending on the volume of the chamber 11 and the type of the chamber 11. Between the air conditioner 10 in the chamber 11, two manufacturing facilities 19 or office facilities 19 are installed. These facilities 19 are rectangular parallelepiped long in the vertical direction, and the height dimension of one of them is larger than the height dimension of the other.

  As an example of each device forming the air conditioner, although not shown, a compressor, a condenser, an expansion valve, an evaporator, an electric heater, a dehumidifier, a humidifier, a heating / cooling coil (heat exchanger), a blower , Air filters, blower motors, control devices, and the like. The equipment storage box 12 is a rectangular parallelepiped that is long in the vertical direction, and the front surface 20 thereof faces the center of the room 21 and the rear surface 22 faces the walls 16 and 17. A suction port 23 that faces the center of the room 21 and sucks air in the room 21 is formed in the lower portion of the front surface 20 of the box 12.

  The blower unit 14A is a rectangular parallelepiped that is long in the lateral direction, and is located in the upper part of the chamber 11 (in the vicinity of the ceiling 24). The air blowing unit 14A includes an inlet 25 into which conditioned air and clean air (hereinafter simply referred to as air) from an air conditioner flows, an outlet 26 that discharges air into the room 21, and an inlet 25 and an outlet 26. And an air flow path 27 extending therebetween. The inflow port 25 is located on the side of the walls 16 and 17 and is connected to the duct 15. The air outlet 26 faces the room 21. The air flow path 27 is provided with two first and second partition plates 28 and 29 (wind speed adjusting mechanism) arranged in the vertical direction. The partition plates 28 and 29 extend in the front-rear direction from the inlet 25 toward the outlet 26. The partition plates 28 and 29 have an upward slope from the inlet 25 toward the outlet 26, and the inclination angle of the first partition plate 28 is larger than that of the second partition plate 29. The air flow path 27 is divided into a third flow path 32 (nth flow path) from the first flow path 30 arranged in the vertical direction by the partition plates 28 and 29. The first flow path 30 is formed above the air flow path 27, the second flow path 32 is formed in the center of the air flow path 27 (between the partition plates 28 and 29), and the third flow path 32 is the air flow path. 27 is formed below.

  The area of the air inlet 33 in the first to third flow paths 30, 31, 32 increases in order from the third flow path 32 toward the first flow path 30. That is, the area of the inlet 33 of the first channel 30 is the largest, the area of the inlet 33 of the third channel 32 is the smallest, and the area of the inlet 33 of the second channel 32 is the first and third flow. It is the middle size of the paths 30 and 32. Therefore, the flow rate of the air flowing into the first to third flow paths 30, 31, 32 increases in order from the third flow path 32 toward the first flow path 30. The area of the air outlet 34 in the first to third flow paths 30, 31, 32 is the same. The air blown from the air conditioner flows into the inlet 25 of the blower unit 14 </ b> A through the duct 15 and is divided into the first flow path 30, the second flow path 31, and the third flow path 32. In the unit 14A, since the area of the inlet 33 of the first flow path 30 is the largest, the flow rate of air flowing into the first flow path 30 is the largest, and the area of the inlet 33 of the third flow path 32 is the smallest. The flow rate of air flowing into the third flow path 32 is the smallest. The flow rate of air flowing into the second flow path 32 is smaller than that of air flowing into the first flow path 30 and larger than that of air flowing into the third flow path 32.

  In this blower unit 14A, the air flow into the first flow path 30 is the highest in the flow paths 30, 31, 32, but the air in the first to third flow paths 30, 31, 32 Since the area of the outlet portion 34 of the first flow path 30 is the same, the wind speed of the air discharged from the flow paths 30, 31, 32 into the room 21 is the fastest in the first flow path 30 and that in the third flow path 32. It becomes the slowest, and the speed of the second flow path 31 is an intermediate speed between the first and third flow paths 30 and 32. Here, assuming that the wind speed of air released from the third flow path 32 into the room 21 is 1, the wind speed of air discharged from the second flow path 31 into the room 21 is discharged from the third flow path 32 into the room 21. 2 to 3 times that of air, and the wind speed of air released from the first flow path 30 to the room 21 is 3 to 5 times that of air released from the third flow path 32 to the room 21. preferable. The wind speed of the air discharged from the third flow path 32 into the room 21 is preferably 0.5 m / sec to 2.0 m / sec, more preferably 0.9 m / sec to 1.1 m / sec. .

  Since the flow rate of the air flowing into the first to third flow paths 30, 31, and 32 increases in order from the third flow path 32 toward the first flow path 30, the blower unit 14 </ b> A is from above the outlet 26. The air with the fastest wind speed is released into the room 21, the air with the slowest wind speed is released into the room 21 from below the blower outlet 26, and the air with an intermediate wind speed from the center in the vertical direction of the blower outlet 26 into the room 21. Released. The blower unit 14A can send air from above the blower outlet 26 to the far side of the room 21, and can send air from below the blower outlet 26 to the room 21 in the vicinity of the unit 14A. Air can be sent to the center of the room 21 between the far center of the room 21 and the vicinity of the unit 14A from the center in the vertical direction.

  As shown in FIG. 2, the air blowing unit 14 </ b> A reaches the back side of the equipment 19 over the manufacturing equipment 19 and office equipment with a high height dimension (arrow L <b> 1 in FIG. 2), and is about the middle. Since the air of the air velocity of the air passes over the manufacturing equipment 19 and the office equipment 19 having a low height and reaches the back side of the equipment 19 (arrow L2 in FIG. 2), the air flow in the room 21 is blocked by the equipment 19. Never happen. The air blowing unit 14 </ b> A can distribute the air evenly throughout the room 21, and can prevent air stagnation in the room 21. By using the air blowing unit 14A, as shown in FIG. 4, it is possible to construct a comfortable air conditioner with no uneven temperature distribution. The air blowing unit 14A does not need to be installed in the ceiling duct work, ceiling finishing work, heat insulation work, etc., so that the unit 14A can be installed at a low cost and can be moved freely. Therefore, the arrangement can be easily changed according to the layout change of the room 21.

  FIG. 5 is a side view of the unit 14B showing the internal structure of the air blowing unit 14B of another example. In FIG. 5, the vertical direction is indicated by an arrow A, and the front-back direction is indicated by an arrow C. The equipment storage box 12 of the air conditioner 10 and each equipment forming the air conditioner are the same as those in FIG. 1, and the arrangement of the equipment 19 in the chamber 11 is the same as that in FIGS. By using 4, the description thereof will be omitted. Hereinafter, only the difference between the blower unit 14B and the unit 14A of FIG. 3 will be described.

  In the air flow path 27 of the blower unit 14B, two first and second partition plates 28 and 29 (wind speed adjusting mechanism) arranged in the vertical direction and three motor dampers 35, 36, and 37 (wind speed adjusting mechanism) are arranged. is set up. These partition plates 28 and 29 extend horizontally in the front-rear direction from the inlet 25 toward the outlet 26. The air flow path 27 is divided into first to third flow paths 30, 31, and 32 (nth flow path) arranged in the vertical direction by the partition plates 28 and 29. The first flow path 30 is formed above the air flow path 27, the second flow path 31 is formed at the center of the air flow path 27, and the third flow path 32 is formed below the air flow path 27. The area of the air inlet 33 and the area of the outlet 34 in the first to third flow paths 30, 31, 32 are the same. The damper 35 is positioned at the approximate center of the first flow path 30, the damper 36 is positioned at the approximate center of the second flow path 31, and the damper 37 is positioned at the approximate center of the third flow path 32.

  The dampers 35, 36, and 37 are formed by a modular roll motor 38 and a swirl vane 39 that swirls through the driving force of the motor 38. Although not shown, the dampers 35, 36, and 37 are connected to a controller, and the motor 38 is rotated by the control signal from the controller and the swirl vane 39 is swung at a predetermined angle. By adjusting the opening degree of the blade 39, the flow rate of the air passing through the first to third flow paths 30, 31, and 32 can be adjusted. When the blades 39 of all the dampers 35, 36, and 37 are horizontal to the flow paths 30, 31, and 32, the flow rate of the air that passes through the flow paths 30, 31, and 32 is the same. The motor dampers 35, 36, and 37 can be parallel blade dampers or counter blade dampers.

  In the blower unit 14B, the motor dampers 35, 36, and 37 are configured so that the flow rate of the air passing through the first to third flow paths 30, 31, and 32 increases in order from the third flow path 32 toward the first flow path 30. The opening degree of the blade 39 is adjusted. The air blown from the air conditioner flows into the inlet 25 of the blower unit 14B through the duct 15 and is divided into the first flow path 30, the second flow path 31, and the third flow path 32. The rotation angle of the blades of the dampers 35, 36, and 37 is that the blade 39 of the damper 37 is the largest, the blade 39 of the damper 35 is the smallest, and the blade 39 of the damper 36 is the damper 35 and the damper 37. It is in the middle of that. Therefore, the opening area of the first flow path 30 regulated by the blade 39 of the damper 35 is the largest, and the air flow rate in the first flow path 30 is the largest. The opening area of the third flow path 32 regulated by the blades 39 of the damper 37 is the smallest, and the air flow rate in the third flow path 32 is the smallest. The flow rate of air in the second flow path 31 is less than that of air in the first flow path 30 and is greater than that of air in the third flow path 32.

  In this unit 14B, although the flow rate of air passing through the first flow path 30 is the largest, the area of the air outlet 34 in the first to third flow paths 30, 31, 32 is the same. The wind speed of the air discharged from the flow paths 30, 31, 32 into the room 21 is the fastest in the first flow path 30, the slowest in the third flow path 32, and that in the second flow path 31. The first and third flow paths 30 and 32 have intermediate speeds. Assuming that the air speed of the air in the third flow path 32 is 1, the air speed of the air in the second flow path 31 is 2 to 3 times that of the air in the third flow path 32, and the air speed of the air in the first flow path 30 is the first. It is preferably 3 to 5 times that of air in the three flow paths 32. In addition, the preferable range of the wind speed of the air in the 3rd flow path 32 is the same as that of 14 A of ventilation units of FIG.

  Since the flow rate of the air passing through the first to third flow paths 30, 31, 32 increases in order from the third flow path 32 toward the first flow path 30, the blower unit 14 </ b> B is from above the outlet 26. The air with the fastest wind speed is released into the room 21, the air with the slowest wind speed is released into the room 21 from below the blower outlet 26, and the air with an intermediate wind speed from the center in the vertical direction of the blower outlet 26 into the room 21. Released. The blower unit 14B can send air from above the blower outlet 26 to the far side of the room 21, and can send air from below the blower outlet 26 to the room 21 in the vicinity of the unit 14B. Air can be sent to the center of the room 21 between the far center of the room 21 and the vicinity of the unit 14B from the center in the vertical direction.

  In the blower unit 14B, as shown in FIG. 2, the air having the highest wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and office equipment 19 having a high height (arrow L1 in FIG. 2), Since air of a certain wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and the office equipment 19 having a low height (arrow L2 in FIG. 2), the air flow in the room 21 is blocked by the equipment 19 Will never be done. The blower unit 14 </ b> B can distribute the air evenly throughout the room 21, and can prevent air stagnation in the room 21. By using the air blowing unit 14B, it is possible to construct a comfortable air conditioner with no uneven temperature distribution, as shown in FIG. This blower unit 14B does not require installation of ceiling duct work, ceiling finishing work, heat insulation work, or the like for installation thereof, so that the unit 14B can be installed at a low cost and can be freely moved. Therefore, the arrangement can be easily changed according to the layout change of the room 21.

  FIG. 6 is a perspective view of the unit 14C showing another example of the internal structure of the blower unit 14C. In FIG. 6, the illustration of the duct 15 is omitted, the vertical direction is indicated by an arrow A, the horizontal direction is indicated by an arrow B, and the front-rear direction is indicated by an arrow C. The equipment storage box 12 of the air conditioner 10 and each equipment forming the air conditioner are the same as those in FIG. 1, and the arrangement of the equipment 19 in the chamber 21 is the same as that in FIGS. By using 4, the description thereof will be omitted. Hereinafter, only the difference of the air blowing unit 14C from the unit 14A of FIG. 3 will be described.

  In the air flow path 27 of the blower unit 14C, two first and second partition plates 28 and 29 (wind speed adjusting mechanism) arranged in the vertical direction, three adjusting plates 40, 41 and 42 (wind speed adjusting mechanism), Is installed. These partition plates 28 and 29 extend horizontally in the front-rear direction from the inlet 25 toward the outlet 26. The air flow path 27 is divided into first to third flow paths 30, 31, and 32 (nth flow path) arranged in the vertical direction by the partition plates 28 and 29. The first flow path 30 is formed above the air flow path 27, the second flow path 31 is formed at the center of the air flow path 27, and the third flow path 32 is formed below the air flow path 27. The area of the air inlet 33 and the area of the outlet 34 in the first to third channels 30, 31 and 32 are the same, and reach the plates 40, 41 and 42 through the air channels 30, 31 and 32. The air flow rate is the same. The adjustment plates 40, 41, 42 are disposed on the inlet 25 side and are individually fixed to the flow path 27. A plurality of air circulation holes 43, 44, 45 for adjusting the flow rate of the conditioned air passing therethrough are formed in the adjustment plates 40, 41, 42.

  The opening areas of the air circulation holes 43, 44, and 45 increase in order from that installed in the third flow path 32 toward that installed in the first flow path 30. That is, the opening area of the air flow hole 43 of the adjustment plate 39 arranged in the first flow path 30 is the largest, that of the adjustment plate 41 arranged in the third flow path 32 is the smallest, and the second flow path 31 That of the arranged adjustment plate 40 is a size intermediate between those of the first and third flow paths 30 and 32. Therefore, the air resistance of the adjustment plate 42 arranged in the third flow path 32 is the largest, and the air resistance of the adjustment plate 40 arranged in the first flow path 30 is the smallest. The air resistance of the adjustment plate 41 disposed in the second flow path 31 is greater than that of the adjustment plate 40 disposed in the first flow path 30 and is greater than that of the adjustment plate 42 disposed in the third flow path 32. Is also small.

  The air blown from the air conditioner flows into the inlet 25 of the blower unit 14C through the duct 15 and is divided into the first flow path 30, the second flow path 31, and the third flow path 32. In this unit 14C, since the air resistance of the adjustment plate 40 installed in the first flow path 30 is small, the wind speed of the conditioned air passing through the flow paths 30, 31, 32 is the fastest in the first flow path 30, The speed of the third flow path 32 is the slowest, and that of the second flow path 31 is an intermediate speed between the first and third flow paths 30 and 32. Assuming that the air speed of the air in the third flow path 32 is 1, the air speed of the air in the second flow path 31 is 2 to 3 times that of the air in the third flow path 32, and the air speed of the air in the first flow path 30 is the first. It is preferably 3 to 5 times that of air in the three flow paths 32. In addition, the preferable range of the wind speed of the air in the 3rd flow path 32 is the same as that of 14 A of ventilation units of FIG.

  Since the air velocity of the air passing through the first to third flow paths 30, 31, 32 increases in order from the third flow path 32 toward the first flow path 30, the blower unit 14 </ b> C is from above the outlet 26. The air with the fastest wind speed is released into the room 21, the air with the slowest wind speed is released into the room 21 from below the blower outlet 26, and the air with an intermediate wind speed from the center in the vertical direction of the blower outlet 26 into the room 21. Released. The blower unit 14C can send air from above the blower outlet 26 to the far side of the room 21 and can send air from below the blower outlet 26 to the room 21 in the vicinity of the unit 14C. Air can be sent to the center of the room 21 between the far center of the room 21 and the vicinity of the unit 14C from the center in the vertical direction.

  As shown in FIG. 2, the air blowing unit 14 </ b> C reaches the back side of the equipment 19 over the manufacturing equipment 19 and office equipment 19 having a high height (air arrow L <b> 1 in FIG. 2). Since air of a certain wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and the office equipment 19 having a low height (arrow L2 in FIG. 2), the air flow in the room 21 is blocked by the equipment 19 It will never be done. The air blowing unit 14 </ b> C can distribute the air evenly throughout the room 21, and can prevent air stagnation in the room 21. By using the air blowing unit 14C, as shown in FIG. 4, it is possible to construct a comfortable air conditioner with no uneven temperature distribution. The air blowing unit 14C can be installed at low cost without the need for performing duct work in the ceiling, ceiling finishing work, heat insulation work, or the like, and can be relocated freely. Therefore, the arrangement can be easily changed according to the layout change of the room 21.

  FIG. 7 is a perspective view of a unit 14D showing another example of the internal structure of the blower unit 14D. In FIG. 7, the illustration of the duct 15 is omitted, the vertical direction is indicated by an arrow A, the horizontal direction is indicated by an arrow B, and the front-rear direction is indicated by an arrow C. The equipment storage box 12 of the air conditioner 10 and each equipment forming the air conditioner are the same as those in FIG. 1, and the arrangement of the equipment 19 in the chamber 21 is the same as that in FIGS. By using 4, the description thereof will be omitted. Hereinafter, only the difference of the air blowing unit 14D from the unit 14A of FIG. 3 will be described.

  In the air flow path 27 of the blower unit 14D, a single adjustment plate 46 (wind speed adjustment mechanism) capable of adjusting the flow rate of air is installed. The adjustment plate 46 is disposed in the vicinity of the air outlet 26 and is fixed to the flow path 27. The adjustment plate 46 is formed with a plurality of air circulation holes 47 for adjusting the flow rate of air passing therethrough. The opening area of the air circulation hole 47 gradually increases from the bottom to the top of the air outlet 26. That is, the opening area of the air flow hole 47 of the adjustment plate 46 above the blowout port 26 is the largest, that of the adjustment plate 46 below the blowout port 26 is the smallest, and the adjustment plate 46 at the center in the vertical direction of the blowout port 26. That is an intermediate size. Therefore, the air resistance of the adjustment plate 46 below the blowout port 26 is the largest, and the air resistance of the adjustment plate 46 above the blowout port 26 is the smallest. The air resistance of the adjustment plate 46 at the center in the vertical direction of the air outlet 26 is larger than that of the adjustment plate 46 above the air outlet 26 and smaller than that of the adjustment plate 46 below the air outlet 26. In this unit 14D, since the air resistance of the adjustment plate 46 above the air outlet 26 is small, the wind speed of the air passing through the air flow path 27 is the fastest above the air outlet 26 and the slowest below the air outlet 26, An intermediate speed is obtained at the center of the air outlet 26 in the vertical direction. In addition, the preferable range of the wind speed of the air under the blower outlet 26 is the same as that of 14 A of ventilation units of FIG.

  In the blower unit 14D, the air resistance of the adjustment plate 46 installed in the air flow path 27 gradually decreases from the lower side of the air outlet 26 toward the upper side. The air having the slowest wind speed is discharged into the room 21 from below the outlet 26, and the air having an intermediate wind speed is released into the room 21 from the center in the vertical direction of the outlet 26. The blower unit 14D can send air from above the blower outlet 26 to the far side of the room 21, and can send air from below the blower outlet 26 to the room 21 in the vicinity of the unit 14D. Air can be sent to the center of the room 21 between the far center of the room 21 and the vicinity of the unit 14D from the center in the vertical direction.

  In the blower unit 14D, as shown in FIG. 2, the air having the highest wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and office equipment 19 having a high height (arrow L1 in FIG. 2), Since air of a certain wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and the office equipment 19 having a low height (arrow L2 in FIG. 2), the air flow in the room 21 is blocked by the equipment 19 It will never be done. The air blowing unit 14 </ b> D can distribute the air evenly throughout the room 21, and can prevent air stagnation in the room 21. By using the air blowing unit 14D, it is possible to construct a comfortable air conditioner with no uneven temperature distribution, as shown in FIG. This blower unit 14D does not require installation of ceiling duct work, ceiling finishing work, heat insulation work, or the like for installation of the blower unit 14D, and the unit 14D can be installed at a low cost and can be moved freely. Therefore, the arrangement can be easily changed according to the layout change of the room 21.

  FIG. 8 is a side view of the unit 14E showing another example of the internal structure of the blower unit 14E. In FIG. 8, the vertical direction is indicated by an arrow A, and the front-back direction is indicated by an arrow C. The equipment storage box 12 of the air conditioner 10 and each equipment forming the air conditioner are the same as those in FIG. 1, and the arrangement of the equipment 19 in the chamber 21 is the same as that in FIGS. By using 4, the description thereof will be omitted. However, the air filter is excluded from each device forming the air conditioner. Hereinafter, only the difference between the blower unit 14E and the unit 14A of FIG. 3 will be described.

  In the air flow path 27 of the blower unit 14E, two first and second partition plates 28 and 29 (wind speed adjusting mechanism) arranged in the vertical direction, three motor dampers 35, 36, and 37 (wind speed adjusting mechanism), An air filter 48 is installed. These partition plates 28 and 29 extend horizontally in the front-rear direction from the inlet 25 toward the outlet 26. The air flow path 27 is divided into first to third flow paths 30, 31, and 32 (nth flow path) arranged in the vertical direction by the partition plates 28 and 29. The first flow path 30 is formed above the air flow path 27, the second flow path 31 is formed at the center of the air flow path 27, and the third flow path 32 is formed below the air flow path 27. The area of the air inlet 33 and the area of the outlet 34 in the first to third flow paths 30, 31, 32 are the same. The damper 35 is positioned at the approximate center of the first flow path 30, the damper 36 is positioned at the approximate center of the second flow path 31, and the damper 37 is positioned at the approximate center of the third flow path 32. These dampers 35, 36, and 37 are the same as those in FIG. 5, and are formed of a module roll motor 38 connected to the controller and a swirl vane 39 that swirls through the driving force of the motor 38. By adjusting the opening degree of the blade 39, the flow rate of the air passing through the first to third flow paths 30, 31, and 32 can be adjusted. When the blades 39 of all the dampers 35, 36, and 37 are horizontal to the flow paths 30, 31, and 32, the flow rate of the air that passes through the flow paths 30, 31, and 32 is the same. The air filter 48 is installed in the vicinity of the inlet 25 in the air flow path 27.

  In the blower unit 14E, the motor dampers 35, 36, and 37 are configured so that the flow rate of the air passing through the first to third flow paths 30, 31, and 32 increases in order from the third flow path 32 toward the first flow path 30. The opening degree of the blade 39 is adjusted. The air blown from the air conditioner flows through the duct 15 into the air filter 48 from the inlet 25 of the blower unit 14B and is purified, and then the first flow path 30, the second flow path 31, and the third flow path. Divide into 32. The rotation angle of the blades of the dampers 35, 36, and 37 is that the blade 39 of the damper 37 is the largest, the blade 39 of the damper 35 is the smallest, and the blade 39 of the damper 36 is the damper 35 and the damper 37. It is in the middle of that feather. Therefore, the opening area of the first flow path 30 regulated by the blade 39 of the damper 35 is the largest, and the air flow rate in the first flow path 30 is the largest. The opening area of the third flow path 32 regulated by the blades 39 of the damper 37 is the smallest, and the air flow rate in the third flow path 32 is the smallest. The flow rate of air in the second flow path 31 is less than that of air in the first flow path 30 and is greater than that of air in the third flow path 32.

  In this unit 14E, although the flow rate of the air passing through the first flow path 30 is the largest, the area of the air outlet 34 in the first to third flow paths 30, 31, 32 is the same. The wind speed of the air discharged from the flow paths 30, 31, 32 into the room 21 is the fastest in the first flow path 30, the slowest in the third flow path 32, and that in the second flow path 31. The first and third flow paths 30 and 32 have intermediate speeds. Assuming that the air speed of the air in the third flow path 32 is 1, the air speed of the air in the second flow path 31 is 2 to 3 times that of the air in the third flow path 32, and the air speed of the air in the first flow path 30 is the first. It is preferably 3 to 5 times that of air in the three flow paths 32. In addition, the preferable range of the wind speed of the air in the 3rd flow path 32 is the same as that of 14 A of ventilation units of FIG.

  Since the flow rate of the air that passes through the first to third flow paths 30, 31, 32 increases in order from the third flow path 32 toward the first flow path 30, the blower unit 14 </ b> E is from above the outlet 26. The air with the fastest wind speed is released into the room 21, the air with the slowest wind speed is released into the room 21 from below the blower outlet 26, and the air with an intermediate wind speed from the center in the vertical direction of the blower outlet 26 into the room 21. Released. The blower unit 14E can send air from above the blower outlet 26 to the far side of the room 21, and can send air from below the blower outlet 26 to the room 21 in the vicinity of the unit 14E. Air can be sent to the center of the room 21 between the far center of the room 21 and the vicinity of the unit 14E from the center in the vertical direction.

  As shown in FIG. 2, the air blowing unit 14E reaches the back side of the equipment 19 over the manufacturing equipment 19 and the office equipment 19 having a high height (air arrow L1 in FIG. 2). Since air of a certain wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and the office equipment 19 having a low height (arrow L2 in FIG. 2), the air flow in the room 21 is blocked by the equipment 19 It will never be done. The blower unit 14 </ b> E can evenly distribute the air throughout the room 21, and can prevent the stagnation of air in the room 21. By using the air blowing unit 14E, as shown in FIG. 4, it is possible to construct a comfortable air conditioner with no uneven temperature distribution. This blower unit 14E does not require installation of ceiling duct work, ceiling finishing work, heat insulation work, etc. for installation of the blower unit 14E, so that the unit 14E can be installed at a low cost and can be moved freely. Therefore, the arrangement can be easily changed according to the layout change of the room 21. Since the air filter 48 is installed in the air blowing unit 14E, air cleaning can be performed in the unit 14E.

  FIG. 9 is a side view of a unit 14F showing another example of the internal structure of the blower unit 14F. In FIG. 9, the illustration of the duct 15 is omitted, the vertical direction is indicated by an arrow A, and the front-rear direction is indicated by an arrow C. The equipment storage box 12 of the air conditioner 10 and each equipment forming the air conditioner are the same as those in FIG. 1, and the arrangement of the equipment 19 in the chamber 21 is the same as that in FIGS. By using 4, the description thereof will be omitted. However, the heat exchanger and the air filter are excluded from each device forming the air conditioner. Hereinafter, only the difference between the blower unit 14F and the unit 14A of FIG. 3 will be described.

The dampers 35, 36, 37, the air filter 48, and the heat exchanger 49 are arranged in the order of the heat exchanger 49, the air filter 48, and the dampers 35, 36, 37 from the inlet 25 toward the outlet 26. A drain pan 50 is installed below the heat exchanger 49.

  These partition plates 28 and 29 extend horizontally in the front-rear direction from the inlet 25 toward the outlet 26. The air flow path 27 is divided into first to third flow paths 30, 31, and 32 (nth flow path) arranged in the vertical direction by the partition plates 28 and 29. The first flow path 30 is formed above the air flow path 27, the second flow path 31 is formed at the center of the air flow path 27, and the third flow path 32 is formed below the air flow path 27. The area of the air inlet 33 and the area of the outlet 34 in the first to third flow paths 30, 31, 32 are the same. The damper 35 is positioned at the approximate center of the first flow path 30, the damper 36 is positioned at the approximate center of the second flow path 31, and the damper 37 is positioned at the approximate center of the third flow path 32. These dampers 35, 36, and 37 are the same as those in FIG. 5, and are formed of a module roll motor 38 connected to the controller and a swirl vane 39 that swirls through the driving force of the motor 38. By adjusting the opening degree of the blade 39, the flow rate of the air passing through the first to third flow paths 30, 31, and 32 can be adjusted. When the blades 39 of all the dampers 35, 36, and 37 are horizontal to the flow paths 30, 31, and 32, the flow rate of the air that passes through the flow paths 30, 31, and 32 is the same.

  In the blower unit 14F, the motor dampers 35, 36, and 37 are configured so that the flow rate of air passing through the first to third flow paths 30, 31, and 32 increases in order from the third flow path 32 to the first flow path 30. The opening degree of the blade 39 is adjusted. The air blown from the air conditioner passes through the duct 15 and flows into the heat exchanger from the inlet 25 of the blower unit 14B to become hot air or cold air, and then flows into the air filter 48 to be purified. The first flow path 30, the second flow path 31, and the third flow path 32 are divided. The rotation angle of the blades of the dampers 35, 36, and 37 is that the blade 39 of the damper 37 is the largest, the blade 39 of the damper 35 is the smallest, and the blade 39 of the damper 36 is the damper 35 and the damper 37. It is in the middle of that feather. Therefore, the opening area of the first flow path 30 regulated by the blade 39 of the damper 35 is the largest, and the air flow rate in the first flow path 30 is the largest. The opening area of the third flow path 32 regulated by the blades 39 of the damper 37 is the smallest, and the air flow rate in the third flow path 32 is the smallest. The flow rate of air in the second flow path 31 is less than that of air in the first flow path 30 and is greater than that of air in the third flow path 32.

  In this unit 14F, although the flow rate of air passing through the first flow path 30 is the largest, the area of the air outlet 34 in the first to third flow paths 30, 31, 32 is the same. The wind speed of the air discharged from the flow paths 30, 31, 32 into the room 21 is the fastest in the first flow path 30, the slowest in the third flow path 32, and that in the second flow path 31. The first and third flow paths 30 and 32 have intermediate speeds. Assuming that the air speed of the air in the third flow path 32 is 1, the air speed of the air in the second flow path 31 is 2 to 3 times that of the air in the third flow path 32, and the air speed of the air in the first flow path 30 is the first. It is preferably 3 to 5 times that of air in the three flow paths 32. In addition, the preferable range of the wind speed of the air in the 3rd flow path 32 is the same as that of 14 A of ventilation units of FIG.

  Since the flow rate of the air passing through the first to third flow paths 30, 31, 32 increases in order from the third flow path 32 toward the first flow path 30, the blower unit 14 </ b> F is from above the outlet 26. The air with the fastest wind speed is released into the room 21, the air with the slowest wind speed is released into the room 21 from below the blower outlet 26, and the air with an intermediate wind speed from the center in the vertical direction of the blower outlet 26 into the room 21.

Since air of a certain wind speed reaches the back side of the equipment 19 over the manufacturing equipment 19 and the office equipment 19 having a low height (arrow L2 in FIG. 2), the air flow in the room 21 is blocked by the equipment 19 It will never be done. The blower unit 14 </ b> F can distribute the air evenly throughout the room 21, and can prevent air stagnation in the room 21. By using the air blowing unit 14F, as shown in FIG. 4, it is possible to construct a comfortable air conditioner with no uneven temperature distribution. This blower unit 14F does not require installation of ceiling duct work, ceiling finishing work, heat insulation work, or the like to install it, so that the unit 14F can be installed at a low cost and can be moved freely. Therefore, the arrangement can be easily changed according to the layout change of the room 21. Since the air filter 48 and the heat exchanger 49 are installed in the blower unit 14F, warm air and cold air can be produced in the unit 14F, and air cleaning can be performed in the unit 14F.

  FIG. 10 is a side view of a unit 14G showing another example of the internal structure of the blower unit 14G. In FIG. 9, the illustration of the duct 15 is omitted, the vertical direction is indicated by an arrow A, and the front-rear direction is indicated by an arrow C. The equipment storage box 12 of the air conditioner 10 and each equipment forming the air conditioner are the same as those in FIG. 1, and the arrangement of the equipment 19 in the chamber 21 is the same as that in FIGS. By using 4, the description thereof will be omitted. However, the heat exchanger, the air filter, and the blower are excluded from each device forming the air conditioner. Hereinafter, only the difference of the air blowing unit 14G from the unit 14A of FIG. 3 will be described.

  In the air flow path 27 of the blower unit 14G, two first and second partition plates 28 and 29 (wind speed adjusting mechanism) arranged in the vertical direction, three motor dampers 35, 36, and 37 (wind speed adjusting mechanism), A heat exchanger 49, a blower 51, and an air filter 48 are installed. The dampers 35, 36, 37, the air filter 48, the heat exchanger 49, and the blower 51 are arranged such that the heat exchanger 49, the blower 51, the air filter 48, and the dampers 35, 36, 37 are directed from the inlet 25 toward the outlet 26. They are arranged in the order. A drain pan 50 is installed below the heat exchanger 49.

  These partition plates 28 and 29 extend horizontally in the front-rear direction from the inlet 25 toward the outlet 26. The air flow path 27 is divided into first to third flow paths 30, 31, and 32 (nth flow path) arranged in the vertical direction by the partition plates 28 and 29. The first flow path 30 is formed above the air flow path 27, the second flow path 31 is formed at the center of the air flow path 27, and the third flow path 32 is formed below the air flow path 27. The area of the air inlet 33 and the area of the outlet 34 in the first to third flow paths 30, 31, 32 are the same. The damper 35 is positioned at the approximate center of the first flow path 30, the damper 36 is positioned at the approximate center of the second flow path 31, and the damper 37 is positioned at the approximate center of the third flow path 32. These dampers 35, 36, and 37 are the same as those in FIG. 5, and are formed of a module roll motor 38 connected to the controller and a swirl vane 39 that swirls through the driving force of the motor 38. By adjusting the opening degree of the blade 39, the flow rate of the air passing through the first to third flow paths 30, 31, and 32 can be adjusted. When the blades 39 of all the dampers 35, 36, and 37 are horizontal to the flow paths 30, 31, and 32, the flow rate of the air that passes through the flow paths 30, 31, and 32 is the same.

  In the blower unit 14G, the motor dampers 35, 36, and 37 are configured so that the flow rate of the air passing through the first to third flow paths 30, 31, and 32 increases in order from the third flow path 32 toward the first flow path 30. The opening degree of the blade 39 is adjusted. The air blown from the air conditioner passes through the duct 15 and flows into the heat exchanger from the inlet 25 of the blower unit 14B to become hot air or cold air, and is then sent to the air filter 48 by the blower 51. After being cleaned at 48, the first flow path 30, the second flow path 31, and the third flow path 32 are divided. The rotation angle of the blades of the dampers 35, 36, and 37 is that the blade 39 of the damper 37 is the largest, the blade 39 of the damper 35 is the smallest, and the blade 39 of the damper 36 is the damper 35 and the damper 37. It is in the middle of that feather. Therefore, the opening area of the first flow path 30 regulated by the blade 39 of the damper 35 is the largest, and the air flow rate in the first flow path 30 is the largest. The opening area of the third flow path 32 regulated by the blades 39 of the damper 37 is the smallest, and the air flow rate in the third flow path 32 is the smallest. The flow rate of air in the second flow path 31 is less than that of air in the first flow path 30 and is greater than that of air in the third flow path 32.

  In this unit 14G, although the flow rate of air passing through the first flow path 30 is the largest, the area of the air outlet 34 in the first to third flow paths 30, 31, 32 is the same. The wind speed of the air discharged from the flow paths 30, 31, 32 into the room 21 is the fastest in the first flow path 30, the slowest in the third flow path 32, and that in the second flow path 31. The first and third flow paths 30 and 32 have intermediate speeds. Assuming that the air speed of the air in the third flow path 32 is 1, the air speed of the air in the second flow path 31 is 2 to 3 times that of the air in the third flow path 32, and the air speed of the air in the first flow path 30 is the first. It is preferably 3 to 5 times that of air in the three flow paths 32. In addition, the preferable range of the wind speed of the air in the 3rd flow path 32 is the same as that of 14 A of ventilation units of FIG.

By using the air blowing unit 14F, as shown in FIG. 4, it is possible to construct a comfortable air conditioner with no uneven temperature distribution. This blower unit 14G need not be installed in the ceiling duct work, ceiling finish work, heat insulation work, etc., and the unit 14G can be installed at low cost, and it can be moved freely. Therefore, the arrangement can be easily changed according to the layout change of the room 21. Since the air filter 48, the heat exchanger 49, and the blower 51 are installed in the air blowing unit 14G, the unit 14F can generate hot air and cold air, and can blow the hot air and cold air. Cleaning can be performed.

  The illustrated air blowing units 14A, 14B, 14C, and 14D are attached to the top 13 of the equipment storage box 12, but only the air blowing units 14A, 14B, 14C, and 14D are installed in the room 21, and the air conditioner body May be provided outside the room. In this case, the air blowing units 14A, 14B, 14C, and 14D are fixed to the upper portions of the walls 16 and 17 of the chamber 11, and the units 14A, 14B, 14C, and 14D are connected to a duct extending from the air conditioner body. Further, in the air blowing units 14A, 14B, and 14C shown in FIGS. 3, 5, and 6, the air flow path 27 is divided into first to third flow paths 30, 31, and 32 by partition plates 28 and 29. The flow path 27 may be divided into first to second flow paths by one partition plate, and the air flow path 27 may be divided into a plurality of sections by three or more partition plates.

  In the blower units 14E, 14F, and 14G, the wind speed adjusting mechanism is formed from the partition plates 28 and 29 and the motor dampers 35, 36, and 37. Like the unit 14A, the partition plates 28 and 29 form the wind speed adjusting mechanism. Similarly to the unit 14C, the partition plates 28 and 29 and the plates 40, 41 and 42 may form a wind speed adjusting mechanism, and the plate 46 forms a wind speed adjusting mechanism as in the unit 14D.
