[0001] The present disclosure relates to a condensing unit for a beverage dispenser. [Background technology]

[0002] Patent Document 1 discloses a beverage dispenser. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-131548 Summary of the Invention [Problem to be solved by the invention]

[0004] A beverage dispenser is used to store and cool beverages to be served to customers. The beverage dispenser includes a chilled water tank for cooling the beverage, a condensing unit for cooling the chilled water tank, and a dispenser for dispensing the cooled beverage to the outside. The condensing unit includes a refrigerant pipe through which a refrigerant for cooling the chilled water tank circulates, a condenser that condenses the refrigerant by heat exchange with outside air, a compressor that compresses the refrigerant, and a fan that cools the compressor.

[0005] Since beverage dispensers are sometimes installed in relatively small spaces, beverage dispensers with a small installation area are required. In order to reduce the installation area of ​​the beverage dispenser, it is necessary to reduce the installation area of ​​the condensing unit. From the perspective of reducing the installation area of ​​the condensing unit, there is room for improvement in the structure of the condensing unit.

[0006] An object of the present disclosure is to provide a condensing unit for a beverage dispenser that can reduce the installation area of ​​the beverage dispenser. [Means for solving the problem]

[0007] The present disclosure provides: a bottom wall having a first side parallel to a first direction; a condenser disposed at least along the first side edge and having a thickness in a second direction perpendicular to the first direction in a plan view; a compressor disposed on the bottom wall and configured to compress a refrigerant; With a single fan A condensing unit for a beverage dispenser, comprising: The fan generates an airflow that flows around the compressor and / or passes through the condenser in the second direction, providing a condensing unit for a beverage dispenser that is not positioned adjacent to the inner and outer surfaces of the condenser.

[0008] According to the condensing unit for a beverage dispenser of the present disclosure, the fan is not disposed adjacent to the inner surface and the outer surface of the condenser, so the arrangement of the condensing unit for a beverage dispenser can be made compact in the second direction. This makes it easier to effectively utilize the space in a plan view of the condensing unit for a beverage dispenser, i.e., the installation area. As a result, it may be possible to reduce the installation area of ​​the condensing unit for a beverage dispenser and the installation area of ​​the beverage dispenser.

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0011] [First embodiment] 1 shows a perspective view of a beverage dispenser 100 including a beverage dispenser condensing unit 1 according to this embodiment. The beverage dispenser 100 has a rectangular parallelepiped housing 102 made up of side panels 102a, a top panel 102b, and a bottom panel (not shown), and a faucet 101 attached to one of the side panels 102a.

[0012] A condensing unit 1 for a beverage dispenser according to the first embodiment (hereinafter referred to as condensing unit 1) is disposed in the lower interior of housing 102. A cooling water tank (not shown) is disposed in the upper interior of housing 102, in which refrigerant cooled in condensing unit 1 circulates to cool the stored beverage. The beverage cooled in the cooling water tank is discharged from beverage dispenser 100 via tap 101 and poured separately into a container such as a glass.

[0013] Next, a condensing unit 1 according to a first embodiment will be described with reference to Figures 2 and 3. Figure 2 shows a perspective view of the condensing unit 1. The condensing unit 1 has a substantially rectangular parallelepiped shape and has a bottom wall 10, four side walls 60 extending upward from the periphery of the bottom wall 10, and an upper wall 70 covering the bottom wall 10 and the side walls 60 from above.

[0014] The side wall 60 is composed of a first side wall 60a, a second side wall 60b, a third side wall 60c, and a fourth side wall 60d. The first side wall 60a is provided with a condenser opening 61 through which a condenser 30 (described later) is disposed so as to be exposed to the outside of the condensing unit 1. In FIG. 2 , the left-right direction of the condensing unit 1 when the first side wall 60a is the front is defined as the first direction, the front-rear direction (the direction perpendicular to the first direction in a plan view) is defined as the second direction, and the up-down direction (the direction perpendicular to the first and second directions) is defined as the third direction. The right and left sides are defined as the X1 side and the X2 side, the front and rear sides are defined as the Y2 side and the Y1 side, and the upper and lower sides are defined as the Z1 side and the Z2 side. These definitions are also used in the second, third, and fourth embodiments described below.

[0015] The third side wall 60c is parallel to the first side wall 60a and is provided on the Y1 side opposite the first side wall 60a. The second side wall 60b is perpendicular to the first side wall 60a and the third side wall 60c and is connected to the X1 sides of the first side wall 60a and the third side wall 60c. The fourth side wall 60d is parallel to the second side wall 60b and is provided on the X2 side opposite the second side wall 60b and is connected to the X2 sides of the first side wall 60a and the third side wall 60c.

[0016] A fan opening 62 for accommodating a single fan 50 (described later) is provided on the Y1 side of the second side wall 60b. The upper wall 70 is also provided with a communication hole 71 for guiding a refrigerant pipe 20 (described later) to a cooling water tank arranged above the condensing unit 1. The size of the communication hole 71 is large enough to allow two refrigerant pipes 20 to pass through, and is smaller than the condenser opening 61 and the fan opening 62.

[0017] FIG. 3 is an exploded perspective view of the condensing unit 1 viewed obliquely from above, with portions of the top wall 70, the fourth side wall 60d, and the first side wall 60a removed. FIG. 3 shows the bottom wall 10, which serves as the base of the condensing unit 1. The bottom wall 10 is substantially rectangular and has a first side edge 10a, a second side edge 10b, a third side edge 10c, and a fourth side edge 10d. That is, the periphery of the bottom wall 10 is formed by the first to fourth side edges 10a to 10d. The first to fourth side walls 60a to 60d each extend from the first to fourth side edges 10a to 10d, respectively, toward the Z1 direction. That is, the first side edge 10a and the third side edge 10c are parallel to the first direction, and the second side edge 10b and the fourth side edge 10d are parallel to the second direction.

[0018] The condensing unit 1 includes a condenser 30 disposed in a condenser opening 61 in the first side wall 60a, a compressor 40 disposed in the center of the bottom wall 10, a fan 50 disposed in a fan opening 62 in the third side wall 60c, and refrigerant piping 20 connecting the condenser 30 and the compressor 40. The condenser 30, the compressor 40, and the refrigerant piping 20 that constitute the condensing unit 1 are filled with refrigerant.

[0019] In this embodiment, the refrigerant used is R600a, R1234yf, R290, R32, R474A, etc., which have relatively low global warming potentials. These refrigerants are flammable and have a specific gravity heavier than air.

[0020] The condenser 30 is arranged along the first side edge 10a. The condenser 30 is a so-called fin-and-tube heat exchanger having multiple thin-film fins 30f, multiple copper tubes 30e penetrating the fins 30f, and two metal plates 30g. In FIG. 3, the multiple fins 30f are arranged in a row in the first direction, and the two metal plates 30g are arranged to sandwich the multiple fins 30f in a row from the X1 side and the X2 side. The multiple copper tubes 30e penetrate the multiple fins 30f and the two metal plates 30g in the first direction. Each of the multiple copper tubes 30e is bent in a U-shape at the X1 side and the X2 side end and connected to the other copper tubes 30e. A refrigerant flows through the multiple copper tubes 30e, and the refrigerant exchanges heat with the outside air via the fins 30f.

[0021] Condenser 30 has a substantially rectangular parallelepiped shape with a predetermined thickness in the second direction. The Z2-side surface of condenser 30, i.e., the surface in contact with bottom wall 10, is referred to as bottom surface 30d, the Z1-side surface, i.e., the surface opposite bottom surface 30d, is referred to as top surface 30c, the Y1-side surface, i.e., the surface on the inside of condensing unit 1, is referred to as inner surface 30a, and the Y2-side surface, i.e., the surface on the outside of condensing unit 1, is referred to as outer surface 30b.

[0022] In the condensing unit 1 of the first embodiment, the outer surface 30b of the condenser 30 is exposed to the outside of the condensing unit 1, and other components, such as a fan, are not arranged adjacent to the inner surface 30a of the condenser 30. In other words, components such as a fan are not arranged adjacent to the outer surface 30b and the inner surface 30a of the condenser 30.

[0023] The fan 50 disposed on the third side wall 60c is a general propeller fan. The condensing unit 1 according to this embodiment is provided with only one fan 50. The fan 50 of the first embodiment has the function of cooling the compressor 40, which becomes overheated during operation of the condensing unit 1, by passing air through it, and the function of promoting heat exchange in the condenser 30 by forced convection by passing outside air through the condenser 30. That is, the fan 50 of the first embodiment is a fan for cooling the compressor 40 and a fan for blowing air through the condenser 30.

[0024] Compressor 40, which is disposed on bottom wall 10, compresses the refrigerant that flows in through refrigerant pipe 20 to a high-temperature, high-pressure state. Compressor 40 is fixed to bottom wall 10 with bolts or the like. Compressor 40 is disposed a predetermined distance on the Y1 side from inner surface 30a of condenser 30 and a predetermined distance on the X2 side from fan 50. Compressor 40 used in the condensing unit according to this embodiment is a constant-speed compressor in which an electric motor (not shown) configured inside compressor 40 rotates at a substantially constant speed.

[0025] The refrigerant piping 20 is a copper pipe. The refrigerant flows through the refrigerant piping 20 to the compressor 40, the condenser 30, and an evaporator (not shown) in the cooling water tank. Specifically, the refrigerant piping 20 is arranged between the compressor 40 and the condenser 30, between the condenser 30 and the evaporator, and between the evaporator and the compressor 40. Note that a capillary tube or the like that reduces the pressure of the refrigerant is provided in the refrigerant piping 20 between the condenser 30 and the evaporator. The refrigerant piping 20 is connected to the compressor 40, the condenser 30, and the evaporator by, for example, brazing.

[0026] Next, the operation of the condensing unit 1 according to the first embodiment will be described.

[0027] When the condensing unit 1 is powered on, power is supplied to the fan 50 and the compressor 40, and the fan 50 and the compressor 40 begin to operate. Operating the compressor 40 circulates the refrigerant in the refrigerant piping 20. The refrigerant is compressed by the compressor 40, becoming a high-temperature, high-pressure gas. The refrigerant flows toward the condenser 30 and passes through the copper tube 30e of the condenser 30. At this time, the refrigerant gives up heat to the outside air by exchanging heat with the outside air through the fins 30f of the condenser 30. As a result, the refrigerant is condensed in the condenser 30. Thereafter, the refrigerant becomes a low-temperature, low-pressure state due to a pressure drop in the capillary tube, cools the water in the cooling water tank in the evaporator, and flows toward the compressor 40 again.

[0028] On the other hand, operating the fan 50 generates an airflow of outside air passing through the fan 50 toward the X1 side. The openings passing between the inside and outside of the condensing unit 1 of the first embodiment are the condenser opening 61, the fan opening 62, and the communication hole 71, and the size of the communication hole 71 is smaller than the condenser opening 61 and the fan opening 62. Therefore, the outside air mainly flows from the outside of the condensing unit 1, passes through the condenser 30 toward the Y1 side, and into the inside of the condensing unit 1, and then passes through the fan 50 toward the X1 side and flows out of the condensing unit 1. In other words, most of the outside air passing through the fan 50 is heat exchanged in the condenser 30. Furthermore, while flowing inside the condensing unit 1, the outside air cools the compressor 40 by flowing around the compressor 40. Since metal plates 30g are arranged on the X1 and X2 sides of the condenser 30, the outside air that passes through the outer surface 30b of the condenser 30 does not flow to the X1 and X2 sides of the condenser 30.

[0029] Conventional condensing units do not have the side walls 60 and top wall 70 of the condensing unit 1 of the first embodiment. Therefore, in order to ensure that most of the outside air flowing through the fan is heat-exchanged in the condenser, the fan must be positioned adjacent to the inner or outer surface of the condenser. Positioning the fan in this manner increases the dimensions of the fan and the condenser in the thickness direction (corresponding to the second direction in the first embodiment). As a result, the components within the condensing unit are unevenly positioned, creating dead space within the condensing unit. In other words, conventional condensing units have limited flexibility in fan positioning in order to maintain the heat exchange performance of the condenser. For this reason, it may be difficult to reduce the installation area of ​​conventional condensing units.

[0030] Meanwhile, in order to protect the global environment, the use of refrigerants with low global warming potential (GWP) is becoming increasingly mandatory, and compressors compatible with these refrigerants have been developed. However, most of these compressors are relatively expensive, energy-saving inverter compressors, and little development has been done on inexpensive constant-speed compressors used in beverage dispensers to accommodate these refrigerants. As a result, there is limited freedom in selecting a compressor compatible with a low GWP refrigerant and suitable for use in beverage dispensers, and a large compressor may be required. As a result, the compressor may take up space within the condensing unit, potentially requiring an increased installation area for the condensing unit. Note that the "space within the condensing unit" in this specification refers to the space within the condensing unit in a plan view (e.g., when viewing the condensing unit from a third direction).

[0031] As described above, in the condensing unit 1 of the first embodiment, even if the fan 50 is not disposed adjacent to the inner surface 30a and the outer surface 30b of the condenser 30, i.e., even if the fan 50 is disposed on a side wall other than the first side wall 60a on which the condenser 30 is disposed, most of the airflow of outside air generated by the fan 50 can pass through the condenser 30 in the second direction. As a result, it may be possible to maintain the heat exchange performance of the condenser 30. This allows for greater freedom in fan placement compared to conventional condensing units, and reduces dead space within the condensing unit 1. As a result, it may be possible to reduce the installation area of ​​the condensing unit 1, or to suppress an increase in the installation area of ​​the condensing unit 1 even when a large-sized compressor is selected.

[0032] The condensing unit 1 for a beverage dispenser according to the first embodiment has the following advantages.

[0033] (1) The condensing unit 1 for a beverage dispenser is a bottom wall 10 having a first side edge 10a parallel to a first direction; a condenser 30 disposed at least along the first side edge 10a and having a thickness in a second direction perpendicular to the first direction in a plan view; a compressor 40 disposed on the bottom wall 10 and compressing a refrigerant; It is equipped with a single fan 50 The fan 50 generates airflow around the compressor 40 and through the condenser 30 in a second direction, and is not positioned adjacent to the inner surface 30a or the outer surface 30b of the condenser 30.

[0034] As a result, the fan 50 is not disposed adjacent to the inner surface 30a and the outer surface 30b of the condenser 30, which prevents an increase in the dimensions of the fan 50 and the condenser 30 in the second direction and prevents a reduction in the space inside the condensing unit 1. This makes it easier to reduce the installation area of ​​the condensing unit 1.

[0035] (2) The condensing unit 1 for the beverage dispenser is a plurality of side walls 60 extending upward from the periphery of the bottom wall 10; An upper wall 70 covering the bottom wall 10 and the plurality of side walls 60 from above; It is equipped with A condenser opening 61 is provided in a first side wall 60a of the plurality of side walls 60, The condenser 30 is disposed in the condenser opening 61, A fan opening 62 is provided in a third side wall 60c of the plurality of side walls 60, The fan 50 is disposed in the fan opening 62 .

[0036] As a result, since the condensing unit 1 is surrounded by the bottom wall 10, the side wall 60, and the top wall 70, the condenser 30 can easily exchange heat with the outside air sufficiently no matter which wall the fan 50 is disposed on. This allows for greater freedom in the placement of the fan 50 in the condensing unit 1 than in condensing units of the prior art, and reduces the space inside the condensing unit 1.

[0037] [Second embodiment] 4 shows a perspective view of a condensing unit 2 according to the second embodiment. Only the configuration that differs from the first embodiment will be described below.

[0038] 4, a blocking plate 31 is provided on an inner surface 30a of the condenser 30. The blocking plate 31 covers the inner surface 30a of the condenser 30 so as to prevent outside air from passing through the inner surface 30a and flowing to the Y1 side.

[0039] A fan 51 is disposed on the upper surface 30c of the condenser 30. The fan 51 of the second embodiment is a so-called crossflow fan 51. Like the fan 50 of the first embodiment, the crossflow fan 51 of the second embodiment is a fan for cooling the compressor 40 and for blowing air through the condenser 30. The crossflow fan 51 has a generally inverted L shape when viewed from the first direction. The crossflow fan 51 has an inlet 51a that draws in outside air and an outlet 51b that discharges outside air. The inlet 51a faces the Z2 side and covers the upper surface 30c of the condenser 30. The outlet 51b faces the Y1 side, i.e., the compressor 40 side.

[0040] The condensing unit 2 according to the second embodiment does not have a side wall or an upper wall.

[0041] When the crossflow fan 51 is operated, outside air enters the outer surface 30b of the condenser 30 and flows through the upper surface 30c of the condenser 30 to the inlet port 51a. The outside air then flows through the crossflow fan 51 and flows toward the Y1 side from the discharge port 51b, and flows around the compressor 40 to cool it. Because the inner surface 30a is covered with the shielding plate 31, most of the outside air that enters the outer surface 30b is air outside the condensing unit 2. In other words, most of the outside air passing through the crossflow fan 51 is heat exchanged in the condenser 30.

[0042] According to this configuration, the crossflow fan 51 is disposed so that the suction port 51a covers the upper surface 30c of the condenser 30. This reduces the space inside the condensing unit 2 and makes it easier to reduce the installation area of ​​the condensing unit 2. Furthermore, the inner surface 30a of the condenser 30 is covered with the shielding plate 31, which prevents air heated by contact with the compressor 40 from exchanging heat with the condenser 30. In this embodiment, the outside air that exchanges heat with the condenser 30 receives heat from the refrigerant flowing inside the condenser 30 (i.e., cools the refrigerant), so it is preferable that the temperature of the outside air is low. Therefore, by covering the inner surface 30a with the shielding plate 31, heat exchange with the outside air in the condenser 30 can be performed efficiently.

[0043] According to the condensing unit 2 for a beverage dispenser according to the second embodiment, The condensing unit 2 for the beverage dispenser is The condenser 30 is provided with a shielding plate 31 that covers the inner surface 30a thereof. The fan 51 is a cross-flow fan 51 having an intake port 51a and an exhaust port 51b. The cross flow fan 51 is disposed so that the suction port 51 a covers the upper surface 30 c of the condenser 30 .

[0044] As a result, cross-flow fan 51 is disposed so that inlet 51a covers upper surface 30c of condenser 30, thereby minimizing the space inside condensing unit 2. Furthermore, shielding plate 31 covers inner surface 30a of condenser 30, allowing for efficient heat exchange.

[0045] [Third embodiment] 5 is a perspective view of a condensing unit 3 according to the third embodiment, seen obliquely from above. Only the configuration that differs from the first embodiment will be described below.

[0046] In FIG. 5, the condenser 32 is disposed along the periphery of the bottom wall 10, i.e., along the first to fourth side edges 10a to 10d. The condenser 32 shown in FIG. 5 is a so-called wire condenser 32. The wire condenser 32 includes a copper tube 32a disposed so as to surround the periphery of the bottom wall 10 and a plurality of wires 32b aligned along the periphery of the bottom wall 10 and extending in the third direction. When viewed from the third direction, the copper tubes 32a are not aligned inside the condensing unit 3, but are instead aligned in a single row. The plurality of wires 32b are arranged in contact with the outside of the copper tube 32a. With this configuration, the thickness of the wire condenser 32 is smaller than that of the fin-and-tube condensers 30 according to the first and second embodiments.

[0047] A refrigerant flows through the copper tube 32a, and heat is exchanged between the refrigerant and the wire 32b. Generally, a wire condenser can exchange heat by natural convection. Therefore, the wire condenser can exchange heat with the outside air without actively passing outside air through the wire condenser, i.e., without placing a fan next to the wire condenser.

[0048] 6 shows a perspective view of a condensing unit 3 according to the third embodiment, viewed obliquely from below. As shown in FIG. 6, a fan opening 11 for accommodating a fan 50 is provided in the center of the bottom wall 10. The fan 50 is disposed on the Z2 side of the fan opening 11. That is, the fan 50 and the fan opening 11 according to the third embodiment are disposed directly below the compressor 40.

[0049] The condensing unit 3 according to the third embodiment does not have a side wall or an upper wall.

[0050] When the fan 50 is operated, the outside air flows from the Z1 side to the Z2 side through the fan opening 11 in the bottom wall 10. This flow of the outside air cools the compressor 40. In addition, a slight flow from the outside to the inside of the condensing unit 3 may also occur, so the outside air may also flow in a direction passing through the wire condenser 32, for example, in the second direction. As described above, the wire condenser 32 can exchange heat through natural convection, but heat exchange can be made more efficient by adding forced convection.

[0051] As described above, there is no need to place the fan 50 adjacent to the wire condenser 32, so the fan 50 can be placed on the Z2 side of the fan opening 11, thereby reducing the space required within the condensing unit 3. Furthermore, because the thickness of the wire condenser 32 is smaller than the thickness of the fin-and-tube condenser 30, the space required within the condensing unit 3 is further reduced.

[0052] If a flammable refrigerant, which has a specific gravity heavier than air, leaks, the leaked refrigerant accumulates in the lower part of the condensing unit, i.e., around the bottom wall 10. The fan 50 arranged on the bottom wall 10 can diffuse the leaked refrigerant, thereby suppressing the concentration of the flammable refrigerant below the lower flammability limit (LFL). Therefore, the fan 50 according to the third embodiment is a fan for cooling the compressor 40, a fan for blowing air through the condenser 32, and a fan for diffusing the refrigerant.

[0053] According to the condensing unit 3 for a beverage dispenser according to the third embodiment, The condenser 32 is a wire condenser 32; The bottom wall 10 is provided with a fan opening 11. The fan 50 is disposed in the fan opening 11 .

[0054] As a result, because the fan 50 is disposed in the fan opening 11 of the bottom wall 10, the space inside the condensing unit 3 is not constricted, and the fan 50 can diffuse any leaked refrigerant. In addition, the fan 50 can generate an airflow that passes outside air through the wire condenser 32, allowing for efficient heat exchange.

[0055] [Fourth embodiment] 7 shows a perspective view of a condensing unit 4 according to the fourth embodiment. Only the configuration that differs from the first embodiment will be described below.

[0056] The condenser 33 shown in FIG. 7 is a radiant heat exchanger 33 with a double-cylindrical structure. The radiant heat exchanger 33 has a double-cylindrical pipe 33a extending in the third direction and headers 33b arranged at the Z1 and Z2 ends of the double-cylindrical pipe 33a. A refrigerant circulates on the Z1 side within the innermost part of the double-cylindrical pipe 33a, and outside air flows around the innermost part. The outside air is heated through heat exchange with the refrigerant in the innermost part, expands, and flows to the Z1 side. In other words, the outside air flows to the Z1 side through the double-cylindrical pipe 33a due to an ascending air current. Therefore, the radiant heat exchanger 33 can exchange heat with outside air without actively passing outside air through the radiant heat exchanger 33, i.e., without arranging a fan adjacent to the radiant heat exchanger 33.

[0057] 8 shows a perspective view of a condensing unit 4 according to the fourth embodiment, viewed obliquely from below. As with the condensing unit 3 according to the third embodiment, a fan opening 11 for accommodating a fan 50 is provided in the center of the bottom wall 10, and the fan 50 is disposed on the Z2 side of the fan opening 11.

[0058] The condensing unit 4 according to the fourth embodiment does not have a side wall or an upper wall.

[0059] When the fan 50 is operated, outside air flows from the Z1 side to the Z2 side through the fan opening 11 in the bottom wall 10. This flow causes the outside air to cool the compressor 40. Meanwhile, the influence of the airflow generated by the fan 50 is relatively small around the radiation heat exchanger 33, but as described above, the radiation heat exchanger 33 can sufficiently exchange heat with the outside air even under such influence.

[0060] With this configuration, as with the condensing unit 3 of the third embodiment, there is no need to place the fan 50 adjacent to the radiant heat exchanger 33, so the fan 50 can be placed on the Z2 side of the fan opening 11, thereby reducing the pressure on the space within the condensing unit 4.

[0061] Furthermore, the fan 50 according to the fourth embodiment can diffuse leaked refrigerant. Therefore, the fan 50 according to the fourth embodiment is a fan for cooling the compressor 40 and also a fan for diffusing the refrigerant.

[0062] According to the condensing unit 4 for a beverage dispenser according to the fourth embodiment, The condenser 33 is a radiation type heat exchanger 33, The bottom wall 10 is provided with a fan opening 11. The fan 50 is disposed in the fan opening 11 .

[0063] As a result, since the fan 50 is disposed in the fan opening 11 of the bottom wall 10, the leaked refrigerant can be diffused while suppressing pressure on the space inside the condensing unit 4.

[0064] The condensing unit for a beverage dispenser according to the present disclosure is not limited to the configuration of the above embodiment, and various modifications are possible.

[0065] In the first embodiment, the fan 50 is disposed on the third side wall 60c, but may be disposed on the second side wall 60b, the fourth side wall 60d, the top wall 70, or the bottom wall 10. In consideration of the ease of replacing the fan, it is preferable that the fan 50 be disposed on the second side wall 60b, the third side wall 60c, or the fourth side wall 60d.

[0066] In the second embodiment, the cross flow fan 51 is disposed so that the suction port 51a covers the upper surface 30c of the condenser 30, but may be disposed so that it covers the lower surface 30d of the condenser 30.
