That is, the use side heat exchanger 3 and the heat source side heat exchanger 6 of the present embodiment are both heat exchangers that perform heat exchange with refrigerant and air.

  In the case of cooling and dehumidification, the use side heat exchanger 3 and the heat source side heat exchanger 6 function as an evaporator and a condenser of a refrigeration cycle, respectively. In the case of heating, the use side heat exchanger and the heat source side heat exchanger function as a condenser and an evaporator, respectively. Switching between cooling and heating is performed by changing the flow of the refrigerant by switching the four-way switching valve 2. When the outdoor air conditioner 100 is a cooling only machine, the four-way switching valve 2 is unnecessary. When the outdoor air-conditioning apparatus 100 is a heating-only device, the four-way switching valve 2 may be provided for the defrost operation.

  The refrigerant used in the outdoor air conditioner 100 is, for example, R32 alone or a mixed refrigerant containing R32. Examples of the mixed refrigerant containing R32 are R452B, R410A, and R454B. In R452B, R32 is 67.0 wt%, R125 is 7.0 wt%, and R1234yf is 26.0%. In R410A, R32 is 50 wt% and R125 is 50 wt%.

  In the air conditioner 100 of the present embodiment, the compressor 1, the heat source side heat exchanger 6, the use side heat exchanger 3, the first fan 7, the second fan 4, the electrical components (not shown) are provided in the casing 10. ) Is housed. The casing 10 has a substantially rectangular parallelepiped shape with a horizontal cross section. The horizontal cross section may be polygonal or rectangular. It may be circular. The casing 10 has four columns 11 a to 11 d, a top plate 13 and a bottom plate 12. The space inside the casing 10 is partitioned by intermediate plates 14 to 17. The intermediate plate also contributes to the reinforcement of the structure of the casing 10. The intermediate plates 14 to 17 are arranged in an appropriate number and at an appropriate position according to the design. The four columns 11a to 11d are vertically arranged at the four corners of a horizontal square as viewed from above. The top plate 13, the bottom plate 12, and the plurality of intermediate plates 14, 15, 16, 17 are fixed to four columns 11a to 11d.

  Decorative members 201 and 202 are attached to the outside of the four side surfaces 20a to 20d of the casing 10. The decorative members on each of the side surfaces 20a to 20d are divided into an upper decorative member 201 and a lower decorative member 202.

  Inside the casing 10, a first fan 7, a heat source side heat exchanger 6, a second fan 4, a use side heat exchanger 3, and the compressor 1 are arranged in this order from the top. The first fan 7 allows air to flow through the heat source side heat exchanger 6. The second fan 4 allows the air to flow through the use-side heat exchanger 3. Between the bottom plate 12 and the intermediate plate 17, not only the compressor 1 but also the accumulator 8 and electric components (not shown) are arranged.

  Further below the bottom plate 12, four casters are mounted. Therefore, the outdoor air conditioner 100 is movable.

  The first fan 7 is a propeller fan. A turbo fan or a sirocco fan may be used. The first fan 7 is mounted such that an air outlet 29 is opened at the center of the top plate 13 so that air can be discharged upward from the center of the top plate. Although not shown, a mesh-shaped plate is further disposed at the outlet 29 at the center of the top plate 13.

  The heat source side heat exchanger 6 includes a heat transfer tube through which a refrigerant flows, and metal fins that promote heat exchange between the refrigerant and air. The heat source side heat exchanger 6 is arranged on all four sides 20 a to 20 d of the casing 10. The coolant does not need to pass through all sides 20a-20d. For example, the refrigerant may be separated into two parts for every two sides, and the refrigerant may be distributed and circulated. Also. It is not always necessary to arrange the heat source side heat exchanger 6 on all four side surfaces 20a to 20d. You may arrange | position only on three surfaces, two surfaces, and one surface.

  The second fan 4 is a turbo fan. It may be a propeller fan or a sirocco fan. The second fan 4 is mounted between the intermediate plates 15 and 16 so as to be hung at the center of the intermediate plate 15. The second fan 4 is driven by a motor different from the motor of the first fan 7, and can be controlled independently.

  The use-side heat exchanger 3 includes a heat transfer tube through which the refrigerant flows while exchanging heat with the air, and metal fins that promote heat exchange between the refrigerant and the air. The use side heat exchangers 3 are arranged on all four side surfaces 20 a to 20 d of the casing 10. The coolant need not pass through all surfaces. For example, the refrigerant may be separated into two parts for every two sides, and the refrigerant may be distributed and circulated. Also. It is not always necessary to arrange the use side heat exchangers 3 on all four side surfaces 20a to 20d. You may arrange | position only on three surfaces, two surfaces, and one surface.

  The electrical components (not shown) are arranged in a space surrounded by the columns 11 a to 11 d, the bottom plate 12, and the intermediate plate 17, similarly to the compressor 1. The electrical components may be located elsewhere. The electrical component is a part of the control unit. The control unit controls a compressor motor, a fan motor, an expansion valve, and the like. The electrical components include electronic devices such as circuit boards.

(3) Configuration of Flowing Air in Outdoor Air Conditioner 100 and Description of Air Flow (3-1) Flow of Air on Usage-Side Heat Exchanger 3 With reference to the drawings, on the usage-side heat exchanger 3 side The flow of air will be described in detail. 3A and 3B, arrows indicate the main air flows in the outdoor air-conditioning apparatus 100 according to the present embodiment.

  When the second fan 4 is operated, the air passes through the lower decorative member 202 from the outside of the outdoor air conditioner 100, from the front side of the use side heat exchanger 3 on the four side surfaces 20a to 20d, and passes through the intermediate plate 16, It is taken into the space between 17. The air passes through the use-side heat exchanger 3 and performs heat exchange with the refrigerant in the use-side heat exchanger 3. The air heated or cooled by the refrigerant passes through the second fan 4 and moves to the space between the intermediate plates 15 and 16, and from the outlets 31a to 31d provided on the four side surfaces 20a to 20d to the space outside. , Is blown out laterally. The outlets 31 a to 31 d are holes formed in the casing 10. Here, the horizontal direction is defined as ± 30 ° in the horizontal direction. The outdoor air-conditioning apparatus 100 according to the present embodiment includes the flap 402, and can blow air in a horizontal direction and at an angle wider than ± 30 ° in the horizontal direction. By changing the direction of the air outlet, it is also possible to close the air outlet only in a certain direction and seal the air outlet in a specific direction. Further, it is preferable that the members used for the outlets 31a to 31d, the flap 402, and the like be made of a weather-resistant material or subjected to a weather-resistant treatment on the surface. Here, examples of the weather resistant material include an acrylonitrile styrene polymer, but are not limited thereto.

(3-2) Flow of air on heat source side heat exchanger 6 side When the first fan 7 is operated, air flows outside the outdoor air conditioner 100 on the front side where the heat source side heat exchanger 6 is arranged. Then, it passes through the upper decorative member 201 and is taken into the space between the intermediate plates 14 and 15. The outside air is taken in on the four side surfaces 20a to 20d. The air taken in from the outside passes through the heat source side heat exchanger 6 and exchanges heat with the refrigerant. The air heated or cooled by the refrigerant passes through the first fan 7 and the outlet 29 at the center of the top plate 13 inside the outdoor air conditioner 100, and is directed upward to the upper outside of the outdoor air conditioner 100. To be blown out.

(4) Configuration of decorative members 201 and 202 The decorative member of the present embodiment will be described in detail with reference to the drawings. 2 is a front view of one side surface 20a of the outdoor air conditioner 100, FIG. 4A is a front view of the lower middle makeup member 202b, and FIGS. 4B, 5A, and 5B are cross-sectional views of the lower makeup member 202.

  As shown in FIG. 2, an outer side surface 20 a of the outdoor air conditioner 100 of the present embodiment has an upper makeup member 201 and a lower makeup member except for a flap 401 disposed at an outlet and a panel 53 below the flap 401. It is covered with a member 202.

  The material constituting the decorative members 201 and 202 is metal. The decorative members are arranged at intervals of 10 mm or less before the heat exchanger. A material having high heat resistance is preferable because it is repeatedly subjected to a heat load.

  The lower decorative member 202 includes three decorative members, namely, a lower left decorative member 202a, a lower middle decorative member 202b, and a lower right decorative member 202c. Each of the decorative members 202a to 202c has a first fitting portion 205p and a second fitting portion 205q on both sides, as shown in the BB cross-sectional view of FIG. 4B. For example, the second fitting portion 205q of the lower middle makeup member 202b is fitted with the first fitting portion 205p of the lower right makeup member 202c, and the lower middle makeup member 202b and the lower right makeup member 202c are connected. Thus, the three decorative members 202a to 202c are combined and used as one decorative member 202. The three decorative members 202a to 202c have the same shape. Since the decorative members 202a to 202c are divided into three, they are smaller than one. Since the same and small ones are manufactured, manufacturing becomes easy.

  In addition, since the fitting portions 205p and 205q of the present embodiment are formed in parallel with the first protruding portion 211, the fitting portions are not conspicuous and are excellent in design.

  Similarly, the upper decorative member 201 is configured by connecting three decorative members 201a to 201c.

  Since the configuration of the six decorative members is almost the same, the lower decorative member 202b, which is one of the lower decorative members 202, will be described in more detail with reference to FIGS. 4A, 5A, and 5B. I do.

  The lower decorative member 202 has a ventilation part 206, a first connection part 207 at both ends thereof, and a second connection part 208. An opening 213 is formed in the ventilation section 206. No openings are formed in the connecting portions 207 and 208. The ventilation section 206 of the lower decorative member 202 corresponds to the suction ports 32a to 32d on the front surface of the use side heat exchanger 3.

  FIG. 5A shows an AA cross section of the ventilation section 206.

  The ventilation unit 206 has a main plate 210 and a first protrusion 211. The main plate 210 has a plurality of openings 213 formed therein. The first projecting portion 211 projects from the main plate 210 between the adjacent openings 213. As described above, the ventilation section 206 is disposed at the suction port 32, and the air flows in the direction of the arrow in FIG. 5A. Thus, the air is rectified by the provision of the first protrusion 211 on the side where air enters, and the ventilation resistance is lower than when the first protrusion 211 is not provided. The protrusion length L of the first protrusion is larger than the width W1 of the opening 213 of the first protrusion. Further, in the present embodiment, the protrusion length L of the first protrusion is larger than the period P of the first protrusion (that is, the same as the period of the opening 213).

  The ventilation section 206 of the decorative member 202 of the present embodiment further has a second protrusion 212. The second projecting portion 212 projects from the first projecting portion 211 in a direction crossing the first projecting portion 211. More specifically, the second protrusion 212 protrudes from the tip of the first protrusion 211. The tip of the first protrusion 211 is flat. When the tip is flat, the structure is such that the pressure is dispersed even when a force is applied to the tip, and the strength of the decorative board can be increased.

  The width of the narrowest portion of the opening is preferably 1 mm or more and 12 mm or less. Here, the width of the narrowest portion of the opening includes not only the width of the opening 213 of the main plate 210 but also the width of the ventilation passage between the adjacent first and second protrusions 211 and 212. In the present embodiment, the portions of w1 and w2 in FIG. 5A are narrow, and w1 = 7 mm and w2 = 8 mm. That is, the width of the narrowest part of the opening is 7 mm. The reason why 1 mm or more is preferable is that if it is less than 1 mm, the ventilation resistance is large. When it is 12 mm or less, the ventilation resistance can be reduced. The width of the narrowest part of the opening is more preferably 8 mm or less. By reducing the width of the opening, the inside of the casing becomes difficult to see from the outside, and the design can be improved.

  The first connecting part 207 and the second connecting part 208 are arranged at both ends of the ventilation part 206. FIG. 5B is a cross-sectional view of the connecting portions 207 and 208 taken along the line BB or line CC. The connecting portions 207 and 208 have a main plate 210, a first projecting portion 211, and a second projecting portion 212. The openings 213 are not formed in the connecting portions 207 and 208. The main plate 210, the first projecting portion 211, and the second projecting portion 212 in the connecting portions 207 and 208 are formed continuously from the ventilation portion 206. In the connection portions 207 and 208, the main plate 210 has a role of arranging the first protrusions 211 at a fixed distance. That is, the main plate 210 can be fixed with a predetermined opening width by the connecting portions 207 and 208.

  Another role of the main plate 210 of the connecting portions 207 and 208 is to block the inside and outside of the casing. In particular, the second connecting portion 208 has a role of protecting a space between the intermediate plate 17 and the bottom plate 12 where the compressor 1 and electric components (not shown) are arranged from dust and water outside the casing.

  On the other hand, the main reason for arranging the first projecting portion 211 and the second projecting portion 212 in the connecting portions 207 and 208 is from a design point of view that creates a unified appearance.

  As above, the configuration of the lower decorative member 202 has been described in detail. The same applies to the case of the upper decorative member 201. The difference is that the use side heat exchanger 3 is replaced by the heat source side heat exchanger 6 and the suction port 32 is replaced by the suction port 33. Therefore, the position of the ventilation part 206 in the makeup member 201 shifts downward from FIG. 4A.

(5) Features (5-1)
The outdoor air conditioner of the present embodiment includes a compressor 1, a heat source side heat exchanger 6, a use side heat exchanger 3, a first fan 7, and a second fan 4 in one casing 10. The side surface of the casing 10 is covered with decorative members 201 and 202. The decorative members 201 and 202 have a main plate 210 and a first protrusion 211. The main plate 210 has a plurality of openings 213. The first projecting portion 211 projects from the main plate 210 between the adjacent openings 213.

  Since the decorative members 201 and 202 of the present embodiment have the first protruding portions 211, the ventilation resistance of the air flowing into and out of the decorative members is lower than when there is no protruding portion. Therefore, although the decorative member of the outdoor air conditioner of the present embodiment has good design, the cooling and heating performance is not significantly impaired.

  In addition, by forming the first protruding portion 211 near the opening 213, the inside of the casing 10 is hard to be directly seen from the outside, and the appearance is improved.

(5-2)
The decorative members 201 and 202 of the outdoor air-conditioning apparatus 100 according to the present embodiment are arranged at the air inlets 32a to 32d and 33a to 33d of the heat exchangers 3 and 6.

  In FIG. 5A, the airflow resistance of the decorative member of this embodiment is lower when air flows in the direction of the arrow than when air flows in the direction opposite to the arrow. The shape of the decorative member has such characteristics. Therefore, the decorative member of the present embodiment has a high effect of reducing the ventilation resistance of the suction port.

(5-3)
The decorative members 201 and 202 of the present embodiment include a ventilation part 206 and connecting parts 207 and 208 at both ends of the ventilation part. The ventilation part 206 is formed in the air inlets 32a to 32d and 33a to 33d. An opening 213 is formed in the ventilation section 206.

  The main plate 210, the first projecting portion 211, and the second projecting portion 212 are formed continuously with the ventilation portion 206 and the connecting portions 207, 208. In the present embodiment, the main plate 210 is a single continuous plate in which the openings 213 are formed. In the ventilation section 206, the main plate 210 does not have continuity due to the opening 213, and the connection sections 207 and 208 have a role of connecting these.

  In addition, the connecting portions 207 and 208 do not have the opening 213 and also serve to block the space inside the casing 10 and the outside space. This can prevent external water, dust, and the like from entering the space where the electrical components and the compressor are arranged.

  The decorative members 201 and 202 of the present embodiment produce a unified aesthetic by arranging the protruding portions 211 and 212 also on the connecting portions 207 and 208.

(5-4)
In the makeup members 201 and 202 of the present embodiment, the tip of the first protrusion 211 bulges in a direction to narrow the opening.

  With this configuration, the inside of the casing 10 is more difficult to see from the outside, and the appearance is improved.

  In the present embodiment, the bulge that narrows the opening is the second protrusion 212. The second projecting portion 212 projects from the first projecting portion 211 in a direction crossing the first projecting portion 211.

  Further, the second protrusion 212 is disposed at the tip of the first protrusion 211.

  In addition, the second protrusion 212 is disposed at the tip of the first protrusion 211 and is flat.

  Since the tip of the first protrusion 211 is flat, the structure is such that the pressure is dispersed even when a force is applied to the tip, and the strength of the decorative board can be increased.

(5-5)
In the decorative members 201 and 202 of the present embodiment, the width of the narrowest portion of the opening is 1 mm or more and 12 mm or less.

  If it is less than 1 mm, the ventilation resistance is large and the air conditioning capacity is reduced. If it is larger than 12 mm, a person may put his hand through the space between the openings 123 and touch the fins of the internal heat exchanger, which may cause injury.

(5-6)
In the decorative members 201 and 202 of the present embodiment, the protruding length (L) of the first protruding portion 211 is larger than the width (W1) of the opening 213.

  With such a configuration, the inside of the casing 10 is hardly seen from the outside, and the design is excellent.

  Further, the effect of suppressing the ventilation resistance is further increased.

(6) Modification (6-1) Modification 1A
FIG. 6 shows a sectional view corresponding to the AA section in FIG. 5A of the decorative member of Modification 1A. Similar to the first embodiment, the decorative member of Modification 1A includes a main plate 210 having a plurality of openings 213 formed therein, and a first protrusion 211 protruding from main plate 210 between adjacent openings 213. Unlike the first embodiment, the decorative member of Modification 1A does not have the second protrusion 212 that can be clearly distinguished from the first protrusion 211. Other configurations of the outdoor air conditioner are the same as those of the first embodiment.

  In the decorative member of Modification 1A, since the tip of the first protrusion 211 bulges in a direction to narrow the opening, the inside of the casing 10 is more difficult to see from the outside, and the appearance is improved.

(6-2) Modification 1B
In the decorative members 201 and 202 of the first embodiment, the second projecting portions 212 project toward the ventilation passages on both sides of the first projecting portion 211. Briefly, the cross-section of the first and second protrusions 211 and 2 was T-shaped. In the decorative member of Modification 1B, as shown in FIG. 7, the second protrusion 212 protrudes only to the ventilation path on one side of the first protrusion 211. In brief, the cross section of the first protrusion 211 and the second protrusion is L-shaped. Other configurations of the outdoor air conditioner are the same as those of the first embodiment.

  In such a case, the same operation and effect as (5-1) to (5-6) can be obtained.

(6-3) Modification 1C

The decorative member of Modification 1C is a further modification of the decorative member of Modification 1B. In Modification 1B, the first protrusion 211 extends straight from the main plate 210, but in Modification 1C, the first protrusion 211 is bent toward one ventilation path. The other configuration of the outdoor air conditioner is the same as that of the modification 1A.

  The decorative member of Modification 1C can also obtain the same operation and effects as (5-1) to (5-6) as in the first embodiment. Furthermore, by adopting such a configuration, the interior becomes less visible from the outside of the casing 10 than in the first embodiment, and the design is improved.

(6-4) Modification 1D
The decorative member according to Modification 1D has only the first protrusion 211 of the first embodiment, and does not have a member corresponding to the second protrusion 212. Other configurations are the same as in the first embodiment.

  The decorative member of Modification 1D has the features of (5-1) to (5-3), (5-5), and (5-6) of the first embodiment.

(6-5) Modification 1E
The decorative member of Modification 1E is an integral decorative member that is not vertically separated. One side surface of the casing 10 is composed of three decorative members, left, center, and right. Other configurations are the same as in the first embodiment.

  Although the decorative member of Modification Example 1E covers the front surfaces of the outlets 31a to 31d, there is no particular problem because the ventilation resistance is small. By covering with a decorative member from top to bottom, a unified aesthetic can be obtained.

(6-6) Modification 1F
The upper decorative member 201 of the first embodiment includes three decorative members 201a to 201c. The upper decorative member 201 of the modified example 1F is constituted by one sheet. The lower decorative member 202 of the modified example 1F is also formed of one sheet.

  The decorative members 201 and 202 of the modified example 1F do not have the fitting portions 205p and 205q, and can form a seamless and seamless design.

(6-7) Modification 1G
The decorative member of Modification 1G is the same as that of the first embodiment, except that the protruding length L of the first protruding portion 211 is smaller than the width W1 of the opening.

  The decorative member of Modification 1G has the features of (5-1) to (5-5) as in the first embodiment.

  While the embodiments of the present disclosure have been described above, it will be understood that various changes in form and details can be made without departing from the spirit and scope of the present disclosure described in the claims. .
