In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
It should be noted that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is merely for convenience in describing and simplifying the description, and does not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 5, a condenser assembly comprises an upper condenser unit 1 and a lower condenser unit 2 which are sequentially arranged from top to bottom, wherein the upper condenser unit 1 and the lower condenser unit 2 are four rows of condenser assemblies, and the number of U tubes of the upper condenser unit 1 is greater than that of the lower condenser unit 2. From this, go up condenser unit 1 and condenser unit 2 down and design into four rows of condenser subassemblies, can increase the cold volume of condenser subassembly, simultaneously, the U pipe quantity of going up condenser unit 1 is more than condenser unit 2's down U pipe quantity, can reduce condenser bottom heat transfer loss.
The upper condenser unit 1 and the lower condenser unit 2 are arranged one above the other. Therefore, after the condenser assembly is assembled, the height of the outdoor unit is increased along the gravity direction, the space layout is more reasonable, and the occupied area is relatively small.
When the outdoor unit operates, gaseous refrigerants enter the condenser assembly, the density of the gaseous refrigerants is low, most of the refrigerants flow towards the upper part of the condenser assembly, the refrigerants below the condenser assembly are reduced, the heat exchange efficiency below the condenser assembly is influenced, and the whole heat exchange of the condenser assembly is uneven; after the number of U tubes of the lower condenser unit 2 is less than that of U tubes of the upper condenser unit 1, when the gaseous refrigerant flows toward the upper condenser unit 1, the number of U tubes of the upper condenser unit 1 is large, the resistance of the refrigerant flowing becomes large, and more refrigerant flows toward the lower condenser unit 2 with relatively small resistance, thereby improving the heat exchange efficiency of the condenser assembly.
The flow paths of the upper condenser unit 1 and the lower condenser unit 2 are all eight-in four-out, that is, the upper condenser unit 1 and the lower condenser unit 2 both comprise eight paths of refrigerant inflow pipelines and four paths of refrigerant outflow pipelines. Therefore, the refrigerant can conveniently and quickly enter the upper condenser unit 1 and the lower condenser unit 2, and the heat exchange efficiency is improved.
The U-tube expansion of the upper condenser unit 1 and the lower condenser unit 2 is the same. Therefore, the integral heat exchange efficiency of the condenser assembly is improved conveniently.
The flow path of the upper condenser unit 1 comprises at least one first flow path unit 11 and the flow path of the lower condenser unit 2 comprises at least one second flow path unit 21. The first flow path unit 11 and the second flow path unit 21 refer to paths through which the refrigerant flows out from the inflow pipe and flows out from the corresponding outflow pipe.
In the first flow path unit 11 and the second flow path unit 21, in the direction from the inside to the outside (windward direction) of the condenser assembly, the first three rows of U tubes of the first flow path unit 11 and the second flow path unit 21 are divided into two U tube flow paths, and the U tube flow paths are formed into a positive U shape, and an inverted U shape, or formed into an inverted U shape, and the positive U shapes are sequentially connected and merged at the fourth row of U tubes.
Specifically, taking the first flow path unit 11 as an example, the refrigerant enters the U-tubes from the inlet 1a, and first passes downward through the third U-tubes of the first row of condensers counted outside from the leeward side, and because the third U-tubes of the first row of condensers are connected with the third U-tubes of the second row of condensers through the elbows, the refrigerant flows into the second row of condenser U-tubes; the refrigerant upwards passes through 3U-shaped tubes in the second row of condensers to form a positive U-shaped path; and then enters a third row of U pipes through an elbow, the refrigerant downwards passes through 3U pipes in the third row of condensers to form an inverted U-shaped path, then passes through a claw-shaped tee joint, is converged with the refrigerant from the inlet 1b in a fourth row of U pipes, and flows out from the outlet 1 c.
The first flow path unit 11 and the second flow path unit 21 are both sets of U-shaped tubes through which refrigerant flows, and the condenser assembly has a certain volume, so that the air conditioner needs the condenser assembly to quickly exchange heat during working, and the first flow path unit 11 and the second flow path unit 21 are respectively provided with a plurality of units, so that the refrigerant multi-path heat exchange is facilitated, and the overall heat exchange efficiency of the condenser assembly is improved.
Thus, each of the first flow path unit 11 and the second flow path unit 21 is of a two-in-one-out configuration, i.e., the first flow path unit 11 or the second flow path unit 21 is provided with two inlets 4 and one outlet 5.
The flow path of the upper condenser unit 1 includes four first flow path units 11, and the number of U tubes of each first flow path unit 11 is equal. Thus, the four first flow path units 11 simultaneously exchange heat, and the heat exchange of the upper condensing unit 1 is ensured to be uniform.
The flow path of the lower condenser unit 2 includes four second flow path units 21; the number of U tubes of the first two second flow path units 21 is equal to the number of U tubes of the first flow path unit 11 in the direction of gravity, and the number of U tubes of the third second flow path unit 21 and the fourth second flow path unit 21 decreases in order. Thus, by designing the structure of the lower condenser unit 2, the heat exchange of the lower condenser unit 2 and the upper condenser unit 1 is promoted to be uniform.
As described above, when the lower condenser unit 2 has four second flow path units 21, the heat exchange efficiency of the lower two second flow path units 21 is 13% lower than that of the upper two second flow path units 21, and it is possible to reduce the number of U tubes of the lower two second flow path units 21 in order to enhance the heat exchange efficiency of the lower two second flow path units 21.
In one mode, in the third second flow path unit 21, the number of U tubes in the fourth row is one less than the number of U tubes in the fourth row of the first two second flow path units 21; in the fourth second flow path unit 21, the number of U tubes in the first three rows is one less than the number of U tubes in the first three rows of the first two second flow path units 21. Thereby, the heat exchange efficiency of the third second flow path unit 21 and the fourth second flow path unit 21 is gradually improved.
In the present embodiment, the number of U tubes of each first flow path unit 11 of the upper condenser unit 1 is 16; along the gravity direction, the number of U tubes of the first two second flow path units 21 of the lower condenser unit 2 is 16, the number of U tubes of the third second flow path unit 21 is 15, and the number of U tubes of the fourth second flow path unit 21 is 13. Therefore, the number of the U pipes of the upper condenser unit 1 and the lower condenser unit 2 is designed, so that the heat exchange efficiency of the condenser assembly is maximized.
The condenser assembly further comprises a side plate 3, the upper condenser unit 1 being connected to the lower condenser unit 2 via the side plate 3, the side plate 3 typically being of metal. Thereby, the fixation of the upper condenser unit 1 and the lower condenser unit 2 is facilitated.
In another fixing mode of the upper condenser unit 1 and the lower condenser unit 2, the upper condenser unit 1 and the lower condenser unit 2 are fixedly connected through a connecting piece, the connecting piece comprises a body with a groove-shaped cross section, a plurality of mounting holes are formed in groove edges of two sides of the body, the groove edge of one side of the body is fixedly connected with the outer sides of the upper condenser unit 1 and the lower condenser unit 2 through the mounting holes respectively, and the groove edge of the other side of the body is fixedly connected with the inner sides of the upper condenser unit 1 and the lower condenser unit 2 through the mounting holes. Therefore, the cross section of the body is groove-shaped, and after the condenser assembly is clamped, the upper condenser unit 1 and the lower condenser unit 2 can be fixedly connected through the mounting holes on the groove edges. The mounting holes are threaded holes or pin holes, correspondingly, threaded holes and pin holes are formed in U-tube fixing plates of the upper condenser unit 1 and the lower condenser unit 2, the threaded holes or the pin holes are fixedly connected through screws and pins, and then the upper condenser unit 1 and the lower condenser unit 2 are fixedly connected through connecting pieces.
In one version, the upper condenser unit 1 comprises 64U tubes and the lower condenser unit 2 comprises 60U tubes. The upper condenser unit 1 is provided with four first flow path units 11, the lower condenser unit 2 is provided with four second flow path units 21, and the first flow path unit 11 and the second flow path unit 21 are both of a two-in one-out configuration.
In the upper condenser unit 1, the four first flow path units 11 are identical, and each path has 16U tubes. In the first flow path unit 11, the refrigerant is divided into two paths in the first three rows of U tubes, flows in from the inlets 4(1a, 1b), is merged in the fourth row of U tubes, and flows out from the outlet 5(1c), so that the heat exchange of the refrigerant in the first flow path unit 11 is realized. The directions and the structures of the other three first flow path units 11 are completely the same, as shown in the figure, in the second first flow path unit 11, the refrigerant flows in from the inlet 4(2a, 2b), and flows out from the outlet 5(2c) after converging; in the third first flow path unit 11, the refrigerant flows in from the inlet 4(3a, 3b), converges, and flows out from the outlet 5(3 c); in the third first flow path unit 11, the refrigerant flows in from the inlet 4(4a, 4b), converges, and flows out from the outlet 5(4 c); in the fourth first channel unit 11, the refrigerant flows in from the inlet 4(4a, 4b), merges, and flows out from the outlet 5(4 c).
In the lower condenser unit 2, the first two second flow path units 21 have the same structure as the first flow path unit 11 in the gravity direction, and each have 16U tubes. Because the heat exchange effect at the bottom of the lower condenser unit 2 is poor, the number of the U tubes of the two second flow path units 21 is respectively reduced to 15 and 13 in order to reduce the heat exchange loss. Wherein, compared with the four rows of U tubes of the first two second flow path units 21, in the third second flow path unit 21, the number of U tubes of the first three rows is unchanged, and the number of U tubes of only the fourth row is 1 less; in the fourth second flow path unit 21, the number of U tubes in the fourth row is unchanged and the number of U tubes in the first three rows is reduced by 1, respectively, relative to the four rows of U tubes in the first two second flow path units 21; in the first second flow path unit 21, the refrigerant is divided into two paths in the first three rows of U-shaped tubes, flows in from the inlet 4(5a, 5b), is converged in the fourth row of U-shaped tubes, and flows out from the outlet 5(5c), so that heat exchange of the refrigerant in the first second flow path unit 21 is realized, and the flow direction of the other three second flow path units 21 is the same; in the second flow path unit 21, the refrigerant flows in from the inlet 4(6a, 6b), converges, and flows out from the outlet 5(6 c); in the third second flow path unit 21, the refrigerant flows in from the inlet 4(7a, 7b), converges, and flows out from the outlet 5(7 c); in the fourth second flow path unit 21, the refrigerant flows in from the inlet 4(8a, 8b), merges, and flows out from the outlet 5(8 c).
An air conditioner comprises the condenser assembly, and therefore the upper condenser unit 1 and the lower condenser unit 2 are designed into four rows of condenser assemblies, the cooling capacity of the condenser assemblies can be increased, meanwhile, the number of U pipes of the upper condenser unit 1 is more than that of the U pipes of the lower condenser unit 2, and heat exchange loss at the bottom of the condenser assemblies can be reduced.
After the air conditioner adopts the condenser assembly, the heat exchange efficiency of the air conditioner is obviously improved compared with that of a single condenser unit.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
