Contents of the invention

The technical problem to be solved by the invention

In the existing air conditioner, the plate-shaped flat heat exchanger is arranged obliquely in the heat exchange chamber, so it is inevitable that many useless spaces will be generated inside the heat exchange chamber, resulting in a decrease in the depth dimension of the indoor unit. Increase. On the other hand, since the external dimensions of the heat exchange chamber increase in proportion to the capacity, it is necessary to provide a wide space inside the heat exchange chamber as the capacity of the heat exchanger increases. These circumstances hinder the compactness of the indoor unit.

In addition, in the conventional air conditioner, since the flat plate-shaped heat exchanger is arranged obliquely in the heat exchange chamber, the distance between the front end and the rear end of the heat exchanger from the air blower is greatly different. Therefore, the air volume of the air passing through the heat exchanger tends to vary depending on the location of the heat exchanger. Variations in the volume of air passing through the heat exchanger degrade the performance of the heat exchanger. Therefore, the existing air conditioners still have room for improvement in terms of fully exerting the performance of the heat exchanger.

As shown in FIG. 4 , the heat exchanger 7 of the ceiling-mounted air conditioner 1 according to the present embodiment is, for example, a fin-and-tube heat exchanger constituted by combining plate-shaped fins and heat transfer tubes. In this embodiment, each of the first to third heat exchange parts 7A, 7B, and 7C includes a plurality of elongated fins 71 and a plurality of heat transfer tubes 72 through which the refrigerant flows.

As shown in FIG. 5 , the fin 71 of the top-mounted air conditioner 1 according to this embodiment is, for example, a square plate made of aluminum, and has a pair of long sides 71L, 71L and a pair of short sides 71S, 71S. The long sides 71L, 71L are parallel to each other. The short sides 71S, 71S are parallel to each other, and extend obliquely so as to cross the long sides 71L, 71L. In other words, the fin 71 is in the shape of a parallelogram in which two sets of opposite sides are respectively parallel.

In addition, a plurality of fitting holes 73 are provided in the fin 71 . The fitting hole 73 has a cylindrical flange portion standing up from the fin 71 obtained by perforating the fin 71 by, for example, burring. The fitting holes 73 are, for example, arranged in eight rows along a direction that coincides with the long side 71L of the fin 71 , and are arranged in three rows along a direction that coincides with the short side 71S.

As shown in FIG. 4 , the fins 71 are arranged in a row at intervals in the width direction W of the indoor unit 2 . In other words, the fins 71 are arranged at intervals from each other in the width direction of the housing 20 . The front end of the flange portion standing up from each fin 71 is in contact with the fitting hole 73 of the adjacent fin 71 so as to be coaxial. Therefore, a ventilation path 74 through which air flows is provided between adjacent fins 71 .

The heat pipe 72 is, for example, a copper pipe excellent in thermal conductivity. Each heat transfer pipe 72 has a straight pipe portion extending straight in the width direction of the indoor unit 2 and a curved pipe portion bent into a substantially U-shape. The straight pipe portion of the heat transfer pipe 72 is continuous with the fitting hole 73 of the fin 71 and passes through it. Thereby, the heat transfer pipe 72 and the fin 71 are thermally connected. The heat transfer pipes 72 are integrated with the fins 71 by making the adjacent fins 71 continuous and penetrating.

And, as shown in FIG. 3 , in this embodiment, one short side 71S of the fin 71 of the first heat exchange part 7A is connected to the short side 71S of the fin 71 of the second heat exchange part 7B on the outlet 28 side. Arranged in such a way that they meet without gaps.

In addition, in this embodiment, the long side 71L of the fin 71 of the first heat exchange part 7A on the blower chamber 3 side and the short side 71S of the air outlet 28 side of the third heat exchange part 7C are in contact without gaps. mode configuration. Alternatively, the other short side 71S of the fin 71 of the first heat exchange portion 7A is arranged so as to be in contact with the long side 71L of the third heat exchange portion 7C on the blower chamber 3 side without a gap.

In this embodiment, if the multi-blade fans 53a, 53b are rotated by the fan motor 51, the multi-blade fans 53a, 53b suck the air in the blower chamber 3 from the suction ports 54a, 54b of the fan casings 52a, 52b, and blow air into the fan casing. Air outlets 55a, 55b of 52a, 52b discharge the sucked air.

Therefore, the air in the building room is sucked into the blower chamber 3 from the suction port 27 of the casing 20 via the suction grille of the ceiling or a duct not shown. The air sucked into the blower chamber 3 is blown toward the heat exchanger 7 from the blower ports 55a, 55b via the fans 52a, 52b.

The first heat exchange portion 7A of the heat exchanger 7 stands upright in the heat exchanger chamber 4 so as to face the air outlets 55a, 55b. Therefore, most of the air blown into the heat exchanger chamber 4 from the air outlets 55a, 55b is It passes between the fins 71 of the first heat exchange unit 7A (ventilation path 74 ).

The remaining air blown into the heat exchanger chamber 4 passes between the fins 71 (ventilation path 74 ) of the second heat exchange portion 7B extending obliquely upward from the upper end of the first heat exchange portion 7A toward the air blower 5 , and from The lower end of the first heat exchange portion 7A faces between the fins 71 (ventilation path 74 ) of the third heat exchange portion 7C extending obliquely downward from the air blower 5 .

As a result, the heat exchanger 7 converts the air blown out from the air outlets 55a and 55b into heat exchange air for cooling or heating by exchanging heat with the refrigerant flowing in the heat transfer pipe 72 . The heat-exchanged air is blown out from the air outlet 28 and sent into the room through the duct.

In the heat exchanger 7 of the present embodiment, the first to third heat exchange parts 7A, 7B, and 7C are combined into a substantially trapezoidal shape, and these are bent into a three-dimensional three-dimensional shape. Therefore, the size of the heat exchanger 7 in the depth direction of the heat exchanger chamber 4 can be shortened compared to a conventional flat heat exchanger arranged obliquely in the heat exchange chamber.

In addition, compared with the case where the conventional flat heat exchanger is disposed obliquely in the heat exchange chamber, in this embodiment, since the first heat exchange portion 7A stands upright in the heat exchanger chamber 4, heat exchange can be performed. The size of the device 7 in the depth direction of the heat exchanger chamber 4 is shortened, and the shortened part is the distance from the opening end of the air outlet 55a, 55b to the front end of the first heat exchange part 7A and the distance from the opening end of the air outlet 55a, 55b. The difference in the distance to the rear end of the second heat exchange part 7B.

Furthermore, in the present embodiment, the heat capacity of the heat exchanger 7 can be sufficiently ensured by bending the heat exchanger 7 . Therefore, in the present embodiment, the heat exchanger 7 having a large capacity can be arranged in the compact heat exchanger chamber 4, and the indoor unit 2 having excellent heat exchanging performance can be provided.

In addition, in this embodiment, the weight of the casing 20 can be reduced along with the downsizing of the casing 20 . Therefore, the workability at the time of attaching the indoor unit 2 to the head space improves. In addition, since the casing 20 is reduced in size, the manufacturing cost of the casing 20 is reduced, and an inexpensive indoor unit 2 can be obtained.

In addition, in the present embodiment, since the first heat exchange unit 7A is erected in the heat exchange chamber 4, compared with the case where the conventional flat heat exchanger is arranged obliquely in the heat exchange chamber, the air flow from the air outlet 54 The difference between the distance from the opening end of the air outlet 54 to the front end of the first heat exchange portion 7A and the distance from the opening end of the blower port 54 to the rear end of the second heat exchange portion 7B is small. Therefore, the air can be blown to the heat exchanger 7 substantially uniformly, and good heat exchange performance can be obtained.

In this embodiment, the second heat exchange part 7B is inclined upward toward the blower chamber side from the upper end of the first heat exchange part 7A, and the third heat exchange part 7C is downward toward the blower chamber side from the lower end of the first heat exchange part 7A. tilt. Therefore, the air is easily blown to the second heat exchange part 7B and the third heat exchange part 7C, and the air volume of the air passing through the upper part and the lower part of the heat exchanger 7 can be ensured. Therefore, it is possible to obtain the heat exchanger 7 having excellent heat exchanging performance.

In addition, in this embodiment, the gap that becomes the cause of the air leakage, which means that the air leaks from the boundary between the first heat exchange part 7A and the second heat exchange part 7B (joint of the first and second heat exchange parts), is excluded. part), and the boundary between the first heat exchange part 7A and the third heat exchange part 7C (joint part of the first and third heat exchange parts) leaks. Therefore, air leaking from the boundaries of the first to third heat exchange portions 7A, 7B, and 7C without heat exchange can be reduced, which is advantageous in improving the heat exchange performance of the heat exchanger 7 .

In addition, in this embodiment, it is possible to reduce the number of members for preventing air from leaking out of the seam without heat exchange.

Therefore, according to this embodiment, it is possible to provide a compact ceiling-mounted air conditioner with good heat exchange efficiency.

In addition, as shown in FIG. 12 , it is possible to adopt a structure in which the fins 71 before bending of the heat exchanger 7 of this embodiment are linear, and the fins 71 of the first to second fins are formed by bending at two places. 3rd heat exchange part 7A, 7B, 7C.

For example, as a manufacturing process, first, the fins 71 of the heat exchanger 7 are formed into a shape having a total length of the first to third heat exchange parts 7A, 7B, and 7C. Next, in order to perform the bending process, the boundary between the first heat exchange portion 7A and the second heat exchange portion 7B (joint portion of the first and second heat exchange portions) and the first heat exchange portion 7A and the second heat exchange portion 7B are cut out according to the bending allowance. A portion of the boundary of the third heat exchange portion 7C (joint portion of the first and third heat exchange portions). In this case, the parts corresponding to the first and third heat exchange parts 7A and 7C are formed in a trapezoidal shape, and the part corresponding to the second heat exchanger part 7B is formed in a parallelogram. Next, when the series of fins 71 are bent, the heat exchanger 7 is formed into a substantially trapezoidal shape.

As shown in FIG. 13 , the angle difference is set so that the inclination angle θ1 of the second heat exchange part 7B arranged at the upper part of the heat exchanger chamber 4 of this embodiment is smaller than the inclination angle θ1 of the third heat exchange part 7B arranged at the lower part of the heat exchanger chamber 4 . The inclination angle θ2 of the exchange part 7C.

The 2nd heat exchange part 7B inclines slightly downward as it gets away from the air blower 5, and 7 C of 3rd heat exchange parts incline a little upward as it gets away from the air blower 5. As shown in FIG. By providing an angle difference between the inclinations of θ1 and θ2, it is possible to reduce the ventilation resistance of the third heat exchange portion 7C located on the lower side where the wind is relatively hard to blow, thereby ensuring the air volume.

According to the present embodiment, it is possible to provide a ceiling-mounted air conditioner with good heat exchange efficiency.

(Embodiment 9)

A ceiling-mounted air conditioner according to Embodiment 9 will be described with reference to FIG. 14 . Among the parts of the present embodiment, the parts that are the same as those in FIGS. 1 to 13 are denoted by the same reference numerals.

14 is a side cross-sectional view showing a heat exchanger of a ceiling-mounted air conditioner according to Embodiment 9. FIG.

As shown in FIG. 14 , the first heat exchange portion 7A located in the central portion of the heat exchanger chamber 4 of the present embodiment is inclined so that the upper end portion of the first heat exchange portion 7A is lower than the lower end portion of the first heat exchange portion 7A. The upper part is more on the windward side.

The second heat exchange unit 7B is located above the heat exchanger chamber 4 . The 2nd heat exchange part 7B is arrange|positioned so that the front-end|tip part of the 2nd heat exchange part 7B may be continuous with the upper end part of 7 A of 1st heat exchange parts.

7 C of 3rd heat exchange parts are located in the lower part of the heat exchanger chamber 4. As shown in FIG. 7 C of 3rd heat exchange parts are arrange|positioned so that the front-end|tip part of 7 C of 3rd heat exchange parts may be continuous with the lower end part of 7 A of 1st heat exchange parts.

For example, the first heat exchange part 7A and the second heat exchange part 7B are arranged such that the long sides 71L of the fins 71 of the first heat exchange part 7A on the side of the blower chamber 3 are blown by the fins 71 of the second heat exchange part 7B. The short sides 71S on the outlet 28 side are in contact with each other without a gap.

In addition, the first heat exchange part 7A and the third heat exchange part 7C are arranged such that the short side 71S on the lower side of the fin 71 of the first heat exchange part 7A is in contact with the outlet 28 of the fin 71 of the third heat exchange part 7C. The side short sides 71S are in contact without gaps.

In this embodiment, the shapes of the fins 71 of the first heat exchange portion 7A and the fins 71 of the third heat exchange portion 7C are line-symmetric. In the second heat exchange part 7B, the length dimension of the long side 71L of the fin 71 is shorter than that of other heat exchange parts.

In the second heat exchange part 7B through which wind is relatively difficult to pass through compared with the first heat exchange part 7A, the number of heat transfer tubes is smaller than other heat exchange parts. For example, if the number of stages (rows) of heat transfer tubes in the first heat exchange part 7A and the third heat exchange part 7C is 10 stages (10 rows), the second heat exchange part 7B has 8 stages (8 rows).

According to this embodiment, the 1st heat exchange part 7A located in a center part inclines with respect to the air blower openings 55a, 55b and the partition plate 26 so that it may receive wind easily. By inclining the first heat exchange part 7A, the air can easily blow to the heat exchanger 7, and the air volume and wind speed of the air passing through the heat exchanger 7 can be ensured. Furthermore, since the air volume and the air speed are ensured, the air speed distribution is improved, and the air blowing performance is improved.

Therefore, in this embodiment, since the flow of wind can be made smooth and it can divide efficiently to each heat exchange part, the top installation type air conditioner with higher performance can be provided.

Moreover, in each embodiment, as shown in FIG. 1, the case 20 which accommodates the air blower 5 and the heat exchanger 7 is suspended by the beam of a building via four hanging bolts HB, for example. Specifically, four suspension parts 29 are fixed to the top plate 21 of the casing 20 . Hanging parts 29 extend horizontally from the four corners of the top plate 21 toward the periphery of the housing 20 , and the lower ends of the hanging bolts HB are connected to the hanging parts 29 .

In addition, in each embodiment, the first heat exchange portion 7A is erected in the heat exchanger chamber 4 , but for example, the first heat exchange portion 7A may be arranged obliquely and formed in a convex shape protruding toward the air outlet 28 . . In this case, among the first heat exchange part 7A, the second heat exchange part 7B, and the third heat exchange part 7C, the short side 71S on the lower side of the fin 71 of the first heat exchange part 7A is in contact with the third heat exchange part. The short side 71S of the fin 71 on the outlet 28 side of 7C is closest to the outlet 28 .

(Embodiment 10)

A top installation type air conditioner according to Embodiment 10 will be described with reference to FIGS. 15 to 17 . Among the parts in this embodiment, the same parts as those in FIGS. 1 to 14 are denoted by the same reference numerals.

15 is a schematic diagram showing a side cross-section of a ceiling-mounted air conditioner according to Embodiment 10. FIG.

As shown in FIG. 15 , the heat exchanger 7 and the drain pan 8 of this embodiment are housed in the heat exchanger chamber 4 of the housing 20 .

The heat exchanger 7 extends in the width direction of the casing 20 . The drain pan 8 is made of a heat insulating material such as styrofoam, for example. Drain pan 8 supports heat exchanger 7 from below to catch drain water dripping from heat exchanger 7 , and surrounds heat exchanger 7 together with heat insulating material 9 . Moreover, the lower surface of the drain pan 8 is covered with the 1st bottom plate 23a.

The heat exchanger 7 of the present embodiment includes a first heat exchange portion 7A, a second heat exchange portion 7B, and a third heat exchange portion 7C. The first to third heat exchange parts 7A, 7B, and 7C are mutually independent members, and are combined into a predetermined three-dimensional three-dimensional shape.

The first to third heat exchange units 7A, 7B, and 7C each include a plurality of elongated plate-shaped fins 71 and a plurality of heat transfer tubes 72 through which the refrigerant flows. The fins 71 are arranged at intervals from each other in the width direction of the housing 20 . The heat transfer pipes 72 are integrated with the fins 71 by making the adjacent fins 71 continuous and penetrating.

The second heat exchange unit 7B is located above the heat exchanger chamber 4 . The second heat exchange portion 7B extends in the depth direction of the casing 20 from the partition plate 26 toward the outlet 28 of the casing 20 . Moreover, the 2nd heat exchange part 7B inclines slightly downward as it approaches the outlet 28 .

7 C of 3rd heat exchange parts are located in the bottom part of the heat exchanger chamber 4, and are separated from the 2nd heat exchange part 7B in the thickness direction of the case 20. The third heat exchange portion 7C extends in the depth direction of the casing 20 from the partition plate 26 toward the outlet 28 of the casing 20 . Moreover, 7 C of 3rd heat exchange parts incline upward a little as it approaches the outlet 28. As shown in FIG. Therefore, each of the second heat exchange unit 7B and the third heat exchange unit 7C has one end located on the blower port 28 side from the partition plate 26 .

7 A of 1st heat exchange parts exist between one end of the 2nd heat exchange part 7B, and one end of 7 C of 3rd heat exchange parts. 7 A of 1st heat exchange parts stand so that they may oppose the partition plate 26, and incline so that they may come closer to the partition plate 26 as it goes toward one end of the 2nd heat exchange part 7B. In other words, the first heat exchange portion 7A gradually approaches the outlet 28 from the end portion on the second heat exchange portion 7B side toward the end portion on the third heat exchange portion 7C side.

Therefore, in the present embodiment, the first to third heat exchange portions 7A, 7B, and 7C are combined in a shape expanding toward the partition plate 26 when the casing 20 is viewed from the side. In other words, in the present embodiment, among the first heat exchange portion 7A, the second heat exchange portion 7B, and the third heat exchange portion 7C, the short side 71S of the fin 71 on the blower outlet 28 side of the third heat exchange portion 7C is the closest. Close to the outlet 28.

The corner portion PC of the long side 71L and the short side 71S on the outlet 28 side of the third heat exchange portion 7C is larger than the corner portion PC of the long side 71L and the short side 71S on the outlet 28 side of the first heat exchange portion 7A. The end portion PA is further protruded toward the outlet 28 side, and offset arrangement is performed.

That is, in the short side 71S of the air outlet 28 side of the third heat exchange part 7C, a protruding part α (step difference) is generated, and the protruding part α is smaller than that of the long side 71L of the first heat exchange part 7A on the air outlet 28 side. It protrudes by a predetermined length l toward the outlet 28 side.

In other words, as shown in FIG. 17, if LA is the shortest distance between the first heat exchange portion 7A and the outlet 28, and LC is the shortest distance between the third heat exchange portion 7C and the outlet 28, then the first heat exchange The portion 7A and the third heat exchange portion 7C are arranged such that the distance LA is longer than the distance LC.

In addition, since the end PA, which is the corner of the long side 71L and the short side 71S on the side of the air outlet 28, is the closest point to the air outlet 28, the shortest distance LA in the first heat exchange part 7A is the distance between the end PA and the air outlet 28. the distance. Similarly, since the end PC, which is the corner of the long side 71L and the short side 71S on the side of the air outlet 28, is the point closest to the air outlet 28, the shortest distance LC in the third heat exchange part 7C is the distance between the end PC and the air outlet. 28 distance.

The heat exchanger 7 of this embodiment generates condensed water Y when the wind X sent from the air blower 5 passes between the fins 71 (ventilation path 74 ) of the heat exchanger 7 during cooling operation. The condensed water Y is generated in each of the first to third heat exchange parts 7A, 7B, and 7C. In particular, the condensed water Y generated in the first heat exchange portion 7A flows down the third heat exchange portion 7C positioned below along the fins 71 .

On the combined surface β of the first heat exchange portion 7A and the third heat exchange portion 7C, since the ends of the fins 71 of the respective heat exchange portions are close together, the condensed water Y tends to stagnate there. Here, when the wind X from the air blower 5 blows, the accumulated condensed water Y will be squeezed in the direction of ventilation, and will be splashed outside the machine from the air outlet 28 .

Therefore, in the present embodiment, the end portion 7C of the third heat exchange portion 7C is shifted so as to protrude toward the air outlet 28 side rather than the end portion PA of the first heat exchange portion 7A, and the protruding portion α is provided. As a result, the condensed water Y stagnant on the combination surface of the first heat exchange portion 7A and the third heat exchange portion 7C stagnates again in the protruding portion α while being sent to the blower outlet 28 side by the wind X, and flows to the second heat exchange portion α. 3 The heat exchanger section 7C flows down. Therefore, the condensed water Y is guided to the drain pan 8 without being splashed by the wind X.

Here, assuming that the end portion PA of the first heat exchange portion 7A is brought into contact with the end portion PC of the third heat exchange portion 7C without providing the protruding portion α (without shifting it), at this time, the condensed water Y is easily The wind X splashes from the end portions PA and PC, which are the front end portions protruding most toward the air outlet 28 side of the heat exchanger 7 . On the other hand, in this embodiment, since the protruding part α which is a step part is provided, the most protruding front end part of the heat exchanger 7 will not be the end part PA. Then, the condensed water Y flowing down from the first heat exchange part 7A does not directly flow to the front end PC of the third heat exchange part 7C, but is re-condensed due to surface tension before reaching the front end PC of the third heat exchange part 7C. Since it stagnates in the protruding part α, it is easy to flow down to the third heat exchange part 7C, and the condensed water Y is hard to splash.

According to this embodiment, the condensed water Y stagnating on the combination surface of the first heat exchange part 7A and the third heat exchange part 7C can be recovered to the third heat exchange part 7C, and splashing of the condensed water Y by the wind X can be suppressed.

In addition, gaps may be generated on the combined surfaces of the first heat exchange portion 7A and the third heat exchange portion 7C due to manufacturing errors, secular deformation, and the like. If a gap is formed on the combined surface of the first heat exchange part 7A and the third heat exchange part 7C, it is considered that more condensed water Y will stagnate in the gap due to surface tension, but according to this embodiment, condensation can be suppressed. Splash of water y.
