1 is a front view of a floor-standing duct type air conditioner, FIG. 2 is a rear view schematically showing the inside of the air conditioner, and FIG. 3 is a side view schematically showing the inside of the air conditioner.
The floor-standing duct type air conditioner described here is, for example, a plurality of air conditioners incorporated in the same frame to form one unit, and a plurality of units are provided in a dedicated machine room provided separately from the air-conditioned room. It is arranged.
The housing (main body) 1 is formed by assembling a metal frame into a rectangular shape in front and rear, left and right, and top and bottom, and a plate material made of sheet metal is attached to the surface thereof. A suction port 3 into which a suction grill 2 is detachably fitted is provided at a substantially central portion of the front surface of the housing 1.

In the top plate portion 1 a of the housing 1, a blow-out port 4 is opened at a substantially corner portion, and a blow-out duct 5 that is only partially shown is inserted into and connected to the blow-out port 4. The blowout duct 5 exits from the machine room, extends to the back of the ceiling of the air-conditioned room, and is branched to communicate with a plurality of indoor blowout openings provided on the ceiling plate.
The inside of the housing 1 is divided into two upper and lower stages by a horizontal partition plate 6, and the lower side of the horizontal partition plate 6 is partitioned into two front and rear chambers by a vertical partition plate 7. The upper side from the horizontal partition plate 6 is not partitioned, and all is an upper chamber 8A. Therefore, the inside of the housing 1 is provided with a total of three chambers: an upper chamber 8A, a lower front chamber 8B, and a lower rear chamber 8C.

A filter 9 is detachably attached to the internal position of the housing 1 facing the suction grill 2 on the front surface of the upper chamber 8A. The fan coil 11 and the air heat exchanger 12 are juxtaposed on the back side of the filter 9 with a predetermined interval, and the fan coil 11 and the air heat exchanger 12 are placed on the first drain pan 13. . A drain hose (not shown) is connected to the first drain pan 13.
A blower 15 is suspended from the lower surface of the housing top plate portion 1a. A specific suspension structure of the blower 15 will be described later. The blower 15 includes a fan motor 16 having a rotating shaft a that protrudes toward the back side of the housing 1, a fan 17 that is fitted and fixed to the rotating shaft a of the fan motor 16, and a fan casing 18 that surrounds the fan 17. Consists of The fan 17 is a multi-blade type that draws air from the central axis direction and blows it out in the circumferential direction as it rotates.

A fan casing 18 is attached to the lower surface of the top plate portion 1 a and surrounds the fan 17. The fan casing 18 includes a suction port 18 a that opens facing the direction of the rotation axis a of the fan motor 16, and a blowout port 18 b that opens in the peripheral portion of the fan 17. The air inlet 18a of the fan casing 18 opens into the upper chamber 8A, and the air outlet 18b is connected to the air outlet 4 provided in the top plate 1a and communicates with the air outlet duct 5.
By driving the blower 15, machine room air outside the housing 1 is sucked into the upper chamber 8 </ b> A in the housing 1 through the suction grill 2 and the filter 9. Then, after circulating through the fan coil 11 and the air heat exchanger 12 and once filling the upper chamber 8A, it is led to the blowout duct 5 via the suction port 18a and the blowout port 18b of the blower fan casing 18, and is covered. It is designed to be blown out to the air conditioning room.

On the other hand, the lower front chamber in the housing 1 is an electrical component chamber 8B, in which an electrical component box 20 is accommodated. The electrical component box 20 is a rectangular box, and contains a large number of electrical components, a wiring cord connecting the electrical components, a printed circuit board, and the like. These electric components and the like are for electrically controlling electric components of the refrigeration cycle section described later.
Most of the electrical components generate heat in response to the action, but include electrical components that generate a large amount of heat, such as a power transistor module. Therefore, although not shown in particular, the exhaust heat of the electrical components released into the electrical component box 20 is exhausted to the outside of the electrical component box 20, and is further led from the electrical component chamber 8B to the upper chamber 8A, so that the electrical component box Means for regulating the temperature rise in 20 is provided.

In the lower rear chamber 8C in the housing 1, a compressor 21, a water-to-refrigerant heat exchanger 22A, a water-to-water heat exchanger 22B, and the like are arranged. In particular, the water-to-refrigerant heat exchanger 22 </ b> A and the water-to-water heat exchanger 22 </ b> B are placed on the second drain pan 23. A drain hose (not shown) is connected to the second drain pan 23. Further, a gas-liquid separator, an electronic expansion valve, a three-way switching valve, and piping (not shown) are arranged in the lower rear chamber 8C.
The compressor 21, the gas-liquid separator, the electronic expansion valve, the water-to-refrigerant heat exchanger 22A, and the air heat exchanger 12 communicate with each other through a refrigerant pipe, and constitute a heat pump type refrigeration cycle circuit. The fan coil 11, the water-to-refrigerant heat exchanger 22A, and the water-to-water heat exchanger 22B are communicated with a three-way switching valve via a water pipe, and constitute a heat source water circulation circuit.

Such a floor-standing duct type air conditioner, particularly, as shown in FIG. 3, the electric component box 20 is provided at a position below the suction port 3, and the fan coil 11 is disposed above the electric component box 20. And facing the suction port 3. The air heat exchanger 12 is provided along with the fan coil 11 on the downstream side of the fan coil 11 in the air flow direction. The fan motor 16 is provided above the fan coil 11 and the air heat exchanger 12, and the fan casing 18 is provided such that the lower end portion is positioned below the upper end portion of the air heat exchanger 12.

Thus, when the compressor 21 is driven to start the refrigeration cycle operation, the refrigerant is compressed in the compressor 21 and circulates along the refrigeration cycle circuit. At the same time, the blower 15 is driven, and the air in the machine room outside the housing 1 is guided from the suction grill 2 to the air heat exchanger 12 via the filter 9 and the fan coil 11 and exchanges heat with the refrigerant circulating there.
The air heat-exchanged by the air heat exchanger 12 is guided along the blowout duct 5 from the suction port portion 18a and the blowout port portion 18b of the fan casing 18 constituting the blower 15, and from the indoor blowout port provided in the air-conditioned room. It is blown out to make room heating or cooling.
During normal operation, the water led from the water supply source to the water inlet of the water pipe passes through the water-to-water heat exchanger 22B and is then led to the fan coil 11 to exchange heat with the air led here. . Then, it is led along the heat source water circulation circuit to the water outlet via the water-to-refrigerant heat exchanger 22A.

During the cooling or heating operation in the intermediate period, the water led from the water supply source to the water inlet of the water pipe passes through the water-to-water heat exchanger 22B, and then is led to the fan coil 11 and the air led here And heat exchange. After that, the three-way switching valve is switched so as to lead from the fan coil 11 to the water-to-water heat exchanger 22B, and after exchanging heat with the water on the water inlet side, the water outlet passes through the water-to-refrigerant heat exchanger 22A. It is led along the heat source water circulation circuit.
Alternatively, the operation of the compressor 21 may be stopped when the room temperature of the air-conditioned room reaches the set temperature, and only the fan coil 11 may be operated instead. At this time, cold water is led from the cooling tower to the fan coil 11 during cooling, and hot water is led from the boiler to the fan coil 11 during heating. By continuously driving the blower 15, cold air or warm air is blown into the air-conditioned room.

Or, normally, only the fan coil 11 is operated, and when the difference between the set temperature and the temperature of the air-conditioned room becomes large and the capacity becomes insufficient with only the fan coil function, the compressor 21 is driven to perform the refrigeration cycle operation. You may make it drive | operate which increases capability.
As described above, in the air conditioner, the inside of the housing 1 has a three-chamber configuration of the upper chamber 8A, the lower front chamber 8B, and the lower rear chamber 8C. In the upper chamber 8A, the fan coil 11, the air heat exchanger 12 and the blower 15 are disposed, the electric component box 20 is disposed in the lower front chamber 8B, and the compressor 21 and the water heat exchanger 22 are disposed in the lower rear chamber 8C. Valves and piping are arranged.
The electrical component box 20 is provided at a position below the suction port 3, the fan coil 11 is provided at the upper part of the electrical component box 20 and opposed to the suction port 3, and the air heat exchanger 12 is connected to the fan coil 11. the air flow direction downstream side, is provided alongside the fan coil 11, fan motor 16 is provided above the fan coil 11 and air heat exchanger 12, the fan casing 18 lower end the upper end of the air heat exchanger 12 It is provided so that it may be in a lower position.

With the chamber configuration and the arrangement configuration of the components in the casing 1 as described above, the inside of the casing 1 can be simplified and the size of the casing 1 can be reduced. The unit can be miniaturized in a state where a plurality of air conditioners are accommodated in the unit. And space reduction of the machine room which arranges a plurality of units is made.
In particular, since the fan casing 18 constituting the blower 15 surrounds the fan 17, an increase in size is inevitable, and occupies a large space in the upper chamber 8A. Here, the fan motor 16 is provided above the fan coil 11 and the air heat exchanger 12, and the position of the lower end of the fan casing 18 is shifted from the upper end of the air heat exchanger 12.
Therefore, the required height of the fan coil 11 and the air heat exchanger 12 can be ensured, and the necessary space of the fan casing 18 can be ensured. While improving the performance as an air conditioner, further downsizing of the apparatus can be promoted.

FIG. 4 shows a modification of the device configuration. The same parts as those described above are denoted by the same reference numerals, and a new description is omitted. (same as below)
A horizontal partition plate 6A that divides the inside of the housing 1 up and down is set lower than the height position previously shown in FIG. 3 at the front ends of the lower front chamber 8B and the lower rear chamber 8C. Accordingly, the gap between the electrical component box 20 and the upper end surface of the water heat exchanger 22 is shortened, but the lower end portions of the suction port 3, the suction grill 2, the filter 9, the fan coil 11 and the air heat exchanger 12 are provided. Can be extended downward. In particular, an increase in the heat exchange area between the fan coil 11 and the air heat exchanger 12 can be obtained, which contributes to an improvement in heat exchange efficiency.
The horizontal partition plate 6A is bent upward from the rear end portion of the first drain pan 13 on which the fan coil 11 and the air heat exchanger 12 are placed, and is extended in the horizontal direction at a predetermined height. Therefore, a sufficient space is ensured between the compressor 21 disposed opposite to the predetermined height portion and the upper end of the discharge pipe b connected to the upper end surface of the compressor 21 and the horizontal partition plate 6A. The setting work in the housing 1 is facilitated.

FIG. 5 is a modified example of a further different apparatus configuration, FIG. 6 is a rear view of the first drain pan 13A, and FIG. 7 is a plan view of the drain guide 6B.
Here, as for the 1st drain pan 13A which mounts the fan coil 11 and the air heat exchanger 12, the rising piece part d height by the side of the suction inlet 3 which is a front side is set higher than what was demonstrated previously, And it is formed horizontally. The rear-side rising piece e is slightly lower than the front-side rising piece d at both ends, and is inclined downward toward the center. The lowest and semicircular cutout 25 is provided at the center.

The horizontal partition 6B is used as a drain guide. The drain guide 6B is inclined obliquely from the front end side so that the substantially lower portion of the rear side rising piece e in the first drain pan 13A is lowest. It is inclined obliquely higher toward the back side from the deepest part and is bent horizontally at a predetermined position. A drain recovery hole 26 is provided at the deepest portion, and this drain recovery hole 26 is located at a position facing the upper end of the water heat exchanger 22. Therefore, a second drain pan on which the water heat exchanger 22 is placed. 23 corresponds to the upper part.
By configuring in this way, for example, when a water breakage accident occurs in the fan coil 11, the first drain pan 13A is provided with a difference in height between the front and rear rising pieces d and e, and therefore is discharged from the drain hose. Even if this is done, the accumulated water overflows from the upper end edge of the rising piece e on the back side. In addition, since the semicircular notch 25 is provided at the center of the rising piece e, the overflow position can be restricted.

The water overflowed from the first drain pan 13A is once received by the drain guide 6B, but is collected in the drain recovery hole 26 due to the shape of the drain guide 6B, and flows down to the water heat exchanger 22 from here. Eventually, the overflowed water is collected in the second drain pan 23 and drained from the drain hose connected to the second drain pan 23. In this way, a drain recovery route can be secured, and the chambers 8A, 8B, 8C in the housing 1 can be prevented from being immersed in water, and the electrical components in the electrical component box 20 are reliably protected.
In addition, in the air conditioning apparatus mentioned above, although all provided the horizontal partition plates 6, 6A, 6B which partition the inside of the housing | casing 1 up and down, it is not limited to this, The air conditioning which is not provided with this horizontal partition plate There is no problem even if it is a device.

8 is a front view for explaining the suspension structure of the blower 15, FIG. 9 is a view for explaining the state of air flow along the fan motor 16, FIG. 10 is a side view of the assembled blower 15, and FIG. B) is a diagram illustrating the assembly of the blower 15. Actually, the fan 17 is attached to the rotating shaft a of the fan motor 16, but is not shown in the drawings except for FIG. 10.
As described above, the blower 15 includes the fan motor 16, the fan 17, and the fan casing 18 surrounding the fan 17. The fan motor 16 is located on the front side of the casing 1, and the fan 17 and the fan casing 18 are located on the rear side of the casing 1. After all, the axial directions of the fan motor 16, the fan 17, and the fan casing 18 coincide with the front-rear direction of the housing 1.

The fan motor 16 is attached and fixed to the motor base 31. That is, a pair of guide rails 30 are provided on the lower surface of the casing top plate portion 1a in parallel with a predetermined interval in the left-right width direction of the casing 1 and extending in the front-rear direction of the casing 1. The upper end piece of the base 31 is slidably hooked. The motor base 31 is bent at least in a substantially U shape so as to accommodate the fan motor 16 therein, and a reinforcing frame f is installed in the left-right direction at the upper surface opening. Bearing portions g provided on both side surfaces of the fan motor 16 are supported and fixed to the support portions h of the motor base 31.
In the upper end piece of the motor base 31 slidably engaged with the guide rail 30, a positioning stopper 32 made of a plate piece is provided at the end opposite to the protruding direction of the rotation axis a of the fan motor 16. It is done.

Next, the assembly process of the blower 15 will be described.
As shown in FIG. 11A, a fan casing 18 is attached to the top plate 1a in advance. In this state, the fan motor 16 supported by the motor base 31 is opposed. As described above, the fan casing 18 is located on the back side of the casing 1, and the fan motor 16 is inserted into the casing upper chamber 8 </ b> A from the front side of the casing 1.
As shown in FIG. 11B, the upper end piece of the motor base 31 is engaged with the guide rail 30, and the motor base 31 is pushed along the guide rail 30 toward the back side of the housing 1. A fan 17 (not shown) that is fitted to the rotation shaft a of the fan motor 16 is inserted into the fan casing 18.

As shown in FIG. 10, when the positioning stopper 32 provided on the motor base 31 abuts against the end edge of the guide rail 30, further insertion of the motor base 31 is restricted. That is, the position of the fan 17 attached to the fan motor 16 with respect to the fan casing 18 is accurately set by simply pushing the fan motor 16 together with the motor base 31.
When removing the fan motor 16 and the fan 17 from the housing 1 as necessary, such as maintenance work, the work opposite to that described above may be performed. In any case, the attachment / detachment of the fan motor 16 can be performed from the front side of the housing 1, so that workability is good.

When the fan motor 16 is attached / detached, the weight of the fan motor 16 is handled by the guide rail 30, so that it can be easily performed by one operator. The fan motor 16 to which the fan 17 is attached is attached and fixed to the housing top plate portion 1a via the guide rail 30, and the fan casing 18 is directly attached to the top plate portion 1a. Stable air blowing performance can be secured.
After the positioning of the motor base 31 is ensured by the positioning stopper 32, the motor base 31 is mounted and fixed to the housing top plate portion 1a via mounting screws. The mounting screw is inserted with the mounting hole provided in the motor base 31 and the case top plate portion 1a looking up from below. However, since the position of the motor base 31 has already come out accurately, the work on the mounting screw is easy. Yes, it can be done smoothly.

In particular, as shown in FIG. 9, when the blower 15 is driven to perform a blowing action, the air around the blower 15 is sucked into the suction port 18 a of the fan casing 18. At the same time, since the fan motor 16 is surrounded by the motor base 31, air between the peripheral surface of the fan motor 16 and the motor base 31 is sucked into the suction port 18a.
Although heat generated by driving the fan motor 16 is dissipated to the periphery, in the conventional configuration without the motor base 31, the heat of the fan motor 16 remains in the periphery as it is. However, as described above, since the fan motor 16 is surrounded by the motor base 31 through a gap here, the warmed air flows from the space to the suction port 18a and is exhausted. That is, the wind speed around the cooling fin j provided on the peripheral surface of the fan motor 16 can be increased, and the fan motor 16 can be efficiently cooled to improve the heat conversion rate.

FIG. 12 is a partial front view of an air conditioner in which the air outlet 18b of the fan casing 18 constituting the blower 15 is attached to the right side plate 1b of the housing 1 to make the right blow, and FIG. 13 is a fan casing constituting the blower 15. It is a partial front view of the air conditioning apparatus which attaches the 18 outlet part 18b to the left side surface plate 1c of the housing | casing 1, and makes left side blowing.
As described above, for example, a plurality of air conditioners are incorporated into the same frame to form one unit, and the plurality of units are arranged in a dedicated machine room. Therefore, some air conditioners are arranged at the uppermost stage of the unit, and some air conditioners are arranged at the middle stage or the lowermost stage.
The air conditioner previously described with reference to FIGS. 1 to 4 has a configuration in which the blowout duct 5 is connected to the housing top plate portion 1a. Or when arrange | positioning at the lowest stage, the blowing duct 5 will become obstructive.

Therefore, as shown in FIG. 12, the air outlet 18 b of the fan casing 18 is connected to the right side plate 1 b of the housing 1 through the auxiliary duct 35. Alternatively, as shown in FIG. 13, the air outlet 18 b of the fan casing 18 is connected to the left side plate 1 c of the housing 1 through the auxiliary duct 35.
In particular, as shown in FIG. 3, not only the blowout port 18 b of the fan casing 18 constituting the blower 15 is connected to the blowout port 4 of the housing top plate 1 a to communicate with the blowout duct 5, but also as shown in FIG. 12. If both right side blowout and left side blowout as shown in FIG. 13 can be selected, the blowout direction can be easily changed in accordance with the duct design at the site, and the workability can be facilitated.
In addition, in order to be able to select both the upper surface blowing and the left and right side blowing, the rotation center O of the fan 17 (fan motor 16) needs to be at the same position. Specifically, the rotation center O of the fan 17 is at the right center in the left-right width direction of the housing 1, and the air outlet 18b of the fan casing 18 is connected to the top plate 1a without changing the position of the rotation center O. Must be configured to touch.
Therefore, in the case of the upper surface blowing shown in FIG. 3, the end surface 18b of the fan casing 18 is directly attached to the housing top plate portion 1a, and the right side blowing and the left side blowing as shown in FIGS. In this case, the auxiliary duct 35 is interposed between the air outlet 18b of the fan casing 18 and the side plates 1b and 1c, but in any case, the rotation center O of the fan 17 is always at the same position.

The distance from the housing top plate portion 1a to the rotation center O of the fan 17 is set to be longer than the radius of curvature of the fan casing 18, and even if the fan casing 18 is rotationally displaced according to the blowing direction, the fan The casing 18 does not come into contact with the housing top plate portion 1a.
Furthermore, multiple air conditioners are built into the same frame to form one unit, and multiple units are placed in a dedicated machine room. If the air conditioner fails, replace each unit. Can respond. Therefore, there is almost no interruption time of the air conditioning operation, and the failed device can be repaired separately.
