Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a condenser of an air conditioner and an air conditioner. Background Art

[0002] As the core component of the air conditioner refrigeration system cycle, the condenser's main function is to participate in heat exchange. It has a crucial impact on the air conditioner's heat exchange capacity, power consumption, reliability and cost.

[0003] However, there is at least one of the following problems in the related art: the refrigerant flow path in the air conditioner condenser and the inlet and outlet pipes between the condenser's liquid outlet manifold and the air inlet manifold are simply set, resulting in the failure to fully realize the heat exchange effect of the condenser. Utility Model Content

[0004] The technical problem solved by the utility model is that the inlet and outlet pipes between the refrigerant flow path in the air-conditioning condenser and the liquid outlet header and the air inlet header of the condenser are simply arranged, resulting in failure to fully realize the heat exchange effect of the condenser.

[0005] In order to solve the above problems, the utility model provides a condenser of an air conditioner, the condenser including a plurality of refrigerant flow paths connected between a refrigerant air inlet manifold and a refrigerant liquid outlet manifold; a first refrigerant pipe group is connected between the plurality of refrigerant flow paths and the refrigerant liquid outlet manifold, and a second refrigerant pipe group is connected between the plurality of refrigerant flow paths and the refrigerant air inlet manifold; the number of refrigerant pipes constituting the first refrigerant pipe group is less than the number of refrigerant pipes constituting the second refrigerant pipe group.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical scheme is: specifically, since the number of inlet and outlet pipes arranged between the refrigerant flow path and the refrigerant liquid outlet manifold is the same as the number of inlet and outlet pipes arranged between the refrigerant flow path and the refrigerant air inlet manifold in the related technology, the heat exchange effect of the condenser cannot be fully realized. In this technical scheme, by adjusting the number of refrigerant pipes constituting the first refrigerant pipe group and the second refrigerant pipe group, specifically by setting the number of refrigerant pipes of the first refrigerant pipe group to be less than the number of refrigerant pipes of the second refrigerant pipe group, the flow rate input from the refrigerant air inlet manifold into multiple refrigerant flow paths in a short period of time is increased, and the flow rate of the refrigerant participating in the refrigeration cycle of the air conditioner is increased to a certain extent, thereby improving the heat exchange effect of the air conditioner.

[0007] In one example of the present invention, at least one of the multiple refrigerant flow paths close to the top air outlet position of the air conditioner is defined as a first refrigerant flow path, and at least one of the multiple refrigerant flow paths away from the top air outlet position is defined as a second refrigerant flow path; the first refrigerant flow path includes the refrigerant pipe located on the windward side of the condenser as the first refrigerant pipe; the second refrigerant flow path includes the refrigerant pipe located on the windward side as the second refrigerant pipe; wherein the number of first refrigerant pipes is less than the number of second refrigerant pipes.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution: Specifically, it can be understood that the wind speed at or near the top air outlet position is greater than that at other positions, which means that the heat exchange efficiency between the first refrigerant flow path located at the top air outlet position and the surrounding external pipe environment is higher than that between the refrigerant flow path not located at the top air outlet position and the surrounding external pipe environment. That is, the refrigerant flow path not located at the top air outlet position is defined as the second refrigerant flow path. Further, the heat exchange efficiency between the refrigerant flow path and the surrounding external pipe environment it is in is also related to the number of refrigerant pipes arranged on the windward side. When there are more refrigerant pipes arranged on the windward side, the heat exchange efficiency is higher. Therefore, combining the above content, in order to reduce the influence of the first refrigerant flow path and the second refrigerant flow path on the surrounding external pipe environment they are in, resulting in a large difference in their heat exchange efficiency, by reasonably adjusting the number of the first refrigerant pipes of the first refrigerant flow path to be less than the number of the second refrigerant pipes, the gap in the heat exchange efficiency between the first refrigerant flow path and the second refrigerant flow path is narrowed, so as to effectively maintain the heat exchange efficiency between each refrigerant flow path to reach equilibrium, thereby improving the overall heat exchange efficiency of the air conditioner.

[0009] In an example of the present utility model, the condenser is provided with an air outlet side opposite to the windward side; the first refrigerant pipe group is arranged on the air outlet side of the condenser; the second refrigerant pipe group is arranged on the windward side of the condenser.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution: Specifically, by arranging the first refrigerant pipe group on the air outlet side and the second refrigerant pipe group on the windward side, the countercurrent principle in the refrigerant circulation process is effectively followed. The countercurrent principle is specifically manifested as the refrigerant flow direction being set in the opposite direction to the wind direction pointing from the windward side to the air outlet side, further improving the overall heat exchange efficiency of the air conditioner.

[0011] In an example of the present utility model, the number of refrigerant pipes forming the first refrigerant flow path is less than or equal to the number of refrigerant pipes forming the second refrigerant flow path; or, the length of the first refrigerant flow path is less than or equal to the length of the second refrigerant flow path.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution: It can be understood that the more the number of refrigerant pipes forming the refrigerant flow path, or the longer the length of the refrigerant flow path forming the refrigerant flow path, it means that its heat exchange efficiency is higher. Therefore, by reasonably adjusting the number or length of the refrigerant pipes of the first refrigerant flow path and the second refrigerant flow path, the heat exchange gap between the two is reduced, and the heat exchange levels between each refrigerant flow path are effectively maintained to be evenly exerted, thereby further improving the overall heat exchange efficiency of the air conditioner.

[0013] In an example of the present utility model, the top air outlet position is arranged in the high-efficiency heat exchange area of the condenser. The condenser is also provided with a sub-high-efficiency heat exchange area and a low-efficiency heat exchange area; the number of refrigerant flow paths located in the high-efficiency heat exchange area is 2 to 3; and / or the number of refrigerant flow paths located in the sub-high-efficiency heat exchange area is 3 to 4; and / or the number of refrigerant flow paths located in the low-efficiency heat exchange area is 2 to 3.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Specifically, by reasonably arranging the number of refrigerant flow paths on each heat exchange area, that is, the high-efficiency heat exchange area, the sub-high-efficiency heat exchange area, and the low-efficiency heat exchange area, the overall heat exchange efficiency of the air conditioner is ensured to be stably exerted.

[0015] In an example of the present utility model, the number of refrigerant pipes in the refrigerant flow path within any one of the high-efficiency heat exchange area, the sub-high-efficiency heat exchange area, and the low-efficiency heat exchange area is 6 to 10.

[0016] In an example of the present utility model, the number of refrigerant pipes in any refrigerant flow path located in the high-efficiency heat exchange area is 6; and / or the number of refrigerant pipes in any refrigerant flow path located in the sub-high-efficiency heat exchange area is 8; and / or the number of refrigerant pipes in any refrigerant flow path located in the low-efficiency heat exchange area is 10.

[0017] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: In order to avoid further widening the heat exchange level between the refrigerant flow paths in the high-efficiency heat exchange area and the refrigerant flow paths in the sub-high-efficiency heat exchange area and the low-efficiency heat exchange area in sequence, by reasonably setting the number of refrigerant pipes in the refrigerant flow path forming the high-efficiency heat exchange area to be less than the number of refrigerant pipes in the refrigerant flow path forming the sub-high-efficiency heat exchange area, and then making the number of refrigerant pipes in the refrigerant flow path forming the sub-high-efficiency heat exchange area less than the number of refrigerant pipes in the refrigerant flow path forming the low-efficiency heat exchange area, that is, in the extending direction from the high-efficiency heat exchange area to the sub-high-efficiency heat exchange area and the low-efficiency heat exchange area in sequence, the number of refrigerant pipes forming the refrigerant flow path is gradually reduced, effectively narrowing the heat exchange gap between the refrigerant flow paths on each heat exchange area, ensuring that the heat exchange levels between each refrigerant flow path are evenly exerted, and thus ensuring that the overall heat exchange efficiency of the air conditioner is stably exerted.

[0018] In an example of the present utility model, the first refrigerant flow path includes 2 refrigerant pipes located on the windward side and 2 refrigerant pipes located on the leeward side; and / or any refrigerant flow path located in the sub-high-efficiency heat exchange area includes 4 refrigerant pipes located on the windward side and 4 refrigerant pipes located on the leeward side; and / or at least one refrigerant flow path located in the low-efficiency heat exchange area includes 4 refrigerant pipes located on the windward side and 6 condensers located on the leeward side; and / or, at least one refrigerant flow path located in the low-efficiency heat exchange area includes 5 refrigerant pipes located on the windward side and 6 condensers located on the leeward side.

[0019] In an example of the present utility model, any one of the multiple refrigerant flow paths includes a first refrigerant branch, a three-way pipe, a second refrigerant branch, and a converging branch that are connected to each other; one end of the first refrigerant branch and one end of the second refrigerant branch are connected to a refrigerant intake manifold through a second refrigerant pipe group; the other end of the first refrigerant branch is connected to the first end of the three-way pipe, and the other end of the second refrigerant branch is connected to the second end of the three-way pipe; the third end of the three-way pipe is connected to one end of the converging branch, and the other end of the converging branch is connected to a refrigerant outlet manifold through a first refrigerant pipe group; wherein, any one of the first refrigerant branch, the second refrigerant branch, and the converging branch is composed of at least two refrigerant pipes.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical solution is: further improving the heat exchange efficiency of the condenser.

[0023] In an example of the present utility model, the multiple refrigerant pipes are arranged in at least two rows between the air outlet side and the windward side; and / or the number of the multiple refrigerant pipes is n, where 56 ≤ n ≤ 72.

[0024] On the other hand, the present utility model also provides an air conditioner, including: an outdoor unit, and the outdoor unit includes a condenser as in any of the above examples.

[0025] Compared with the prior art, the technical effect achieved by adopting this technical solution is: being able to achieve the technical effects of the technical solutions in any of the above examples, which will not be elaborated here.

[0026] After adopting the technical solution of the present utility model, the following technical effects can be achieved:

[0027] (1) By adjusting the number of refrigerant pipes constituting the first refrigerant pipe group and the second refrigerant pipe group, specifically by setting the number of refrigerant pipes in the first refrigerant pipe group to be less than the number of refrigerant pipes in the second refrigerant pipe group, the flow rate of the refrigerant input into the multiple refrigerant flow paths from the refrigerant intake manifold in a short time is increased, and to a certain extent, the flow velocity of the refrigerant participating in the refrigeration cycle of the air conditioner is increased, thereby improving the heat exchange effect of the air conditioner;

[0028] (2) Specifically, it can be understood that the wind speed at or near the top air outlet position is greater than that at other positions, which means that the heat exchange efficiency between the first refrigerant flow path located at the top air outlet position and the surrounding external pipe environment is higher than that between the refrigerant flow path not located at the top air outlet position and the surrounding external pipe environment. That is, the refrigerant flow path not located at the top air outlet position is defined as the second refrigerant flow path. Further, the heat exchange efficiency between the refrigerant flow path and the surrounding external pipe environment where it is located is also related to the number of refrigerant pipes arranged on the windward side. When there are more refrigerant pipes arranged on the windward side, the heat exchange efficiency is higher. Therefore, combining the above content, in order to reduce the large difference in heat exchange efficiency between the first refrigerant flow path and the second refrigerant flow path caused by the influence of their respective surrounding external pipe environments, by reasonably adjusting the number of the first refrigerant pipes of the first refrigerant flow path to be less than the number of the second refrigerant pipes, the gap in heat exchange efficiency between the first refrigerant flow path and the second refrigerant flow path is narrowed, so as to effectively maintain the balance of the heat exchange efficiency among the refrigerant flow paths, thereby improving the overall heat exchange efficiency of the air conditioner;

Detailed Embodiments

[0034] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0035] See Figure 1 , which is a schematic structural diagram of a condenser 100 of an air conditioner provided by an embodiment of the present utility model. Specifically, the condenser 100 includes a plurality of refrigerant flow paths connected between a refrigerant inlet header and a refrigerant outlet header; a first refrigerant pipe group 3 is communicated between the plurality of refrigerant flow paths and the refrigerant outlet header, and a second refrigerant pipe group 1 is communicated between the plurality of refrigerant flow paths and the refrigerant inlet header; the number of refrigerant pipes 4 constituting the first refrigerant pipe group 3 is less than the number of refrigerant pipes 4 constituting the second refrigerant pipe group 1.

[0036] Specifically, in the related art, the number of inlet and outlet pipes provided between the refrigerant flow path and the refrigerant outlet header is the same as the number of inlet and outlet pipes provided between the refrigerant flow path and the refrigerant inlet header, resulting in the failure to fully achieve the heat exchange effect of the condenser 100. In the present technical solution, by adjusting the number of refrigerant pipes 4 constituting the first refrigerant pipe group 3 and the second refrigerant pipe group 1, specifically, by setting the number of refrigerant pipes 4 in the first refrigerant pipe group 3 to be less than the number of refrigerant pipes 4 in the second refrigerant pipe group 1, the flow rate of the refrigerant input into the plurality of refrigerant flow paths from the refrigerant inlet header in a short time is increased, and to a certain extent, the flow rate of the refrigerant participating in the refrigeration cycle of the air conditioner is increased, thereby improving the heat exchange effect of the air conditioner.

[0037] Preferably, at least one of the plurality of refrigerant flow paths close to the top air outlet position of the air conditioner is defined as the first refrigerant flow path 10, and at least one of the plurality of refrigerant flow paths far from the top air outlet position is defined as the second refrigerant flow path 20; the first refrigerant flow path 10 includes a refrigerant pipe 4 located on the windward side 101 of the condenser 100 as the first refrigerant pipe; the second refrigerant flow path 20 includes a refrigerant pipe 4 located on the windward side 101 as the second refrigerant pipe; wherein, the number of the first refrigerant pipes is less than the number of the second refrigerant pipes.

[0038] Specifically, it can be understood that the wind speed at or near the top air outlet position is greater than that at other positions, which means that the heat exchange efficiency between the first refrigerant flow path 10 located at the top air outlet position and the surrounding external pipe environment is higher than that between the refrigerant flow path not located at the top air outlet position and the surrounding external pipe environment. That is, the refrigerant flow path not located at the top air outlet position is defined as the second refrigerant flow path 20. Further, the heat exchange efficiency between the refrigerant flow path and the surrounding external pipe environment where it is located is also related to the number of refrigerant pipes 4 arranged on the windward side 101. When the number of refrigerant pipes 4 arranged on the windward side 101 is larger, the heat exchange efficiency is higher. Therefore, combining the above content, in order to reduce the influence of the first refrigerant flow path 10 and the second refrigerant flow path 20 by their respective surrounding external pipe environments, resulting in a large difference in their heat exchange efficiency, by reasonably adjusting the number of the first refrigerant pipes of the first refrigerant flow path 10 to be less than the number of the second refrigerant pipes, the gap in the heat exchange efficiency between the first refrigerant flow path 10 and the second refrigerant flow path 20 is reduced, so as to effectively maintain the balance of the heat exchange efficiency among the refrigerant flow paths, thereby improving the overall heat exchange efficiency of the air conditioner.

Specifically, by arranging the first refrigerant pipe group 3 on the air outlet side 102 and arranging the second refrigerant pipe group 1 on the windward side 101, the countercurrent principle in the refrigerant circulation process is effectively followed. The countercurrent principle is specifically manifested as the refrigerant flow direction being arranged in the opposite direction to the wind direction pointing from the windward side 101 to the air outlet side 102, further improving the overall heat exchange efficiency of the air conditioner.

It can be understood that the more the number of the refrigerant pipes 4 forming the refrigerant flow path, or the longer the length of the refrigerant flow path, the higher the heat exchange efficiency. Therefore, by reasonably adjusting the number or length of the refrigerant pipes 4 of the first refrigerant flow path 10 and the second refrigerant flow path 20, the heat exchange gap between the two is reduced, and the heat exchange levels among the refrigerant flow paths are effectively maintained to be evenly exerted, thereby further improving the overall heat exchange efficiency of the air conditioner.
