Moreover, the air inlet 101 and the liquid outlet 102 are located on the same side of the pipe section of the first branch pipeline 100 .

Optionally, the inlet 101 and the outlet 102 of the first branch pipeline 100 are located on the same side of the condenser 10 .

The condenser 10 includes a plurality of first branch pipelines 100 , the inlet 101 and the liquid outlet 102 of the plurality of first branch pipelines 100 are located on the same side of the condenser 10 . In this way, after the condenser 10 is installed, the plurality of first branch pipelines 100 of the condenser 10 are used to be uniformly stored on one side of the condenser 10, or in one set of the air conditioner. In a small space, it is convenient for unified storage and management.

The air inlet 101 and the liquid outlet 102 of the first branch pipeline 100 are not only located on the same side of the condenser 10, but also arranged close to each other. In this way, it is convenient for operators to disassemble and maintain.

Optionally, the first branch pipeline 100 includes a plurality of sequentially connected pipe sections pierced through the condenser 10; wherein, the plurality of pipe sections are distributed in at least two rows, and the pipe sections in adjacent rows are arranged in a staggered position.

The plurality of sequentially connected pipe sections are distributed in at least two rows, and the pipe sections in adjacent rows are arranged in a staggered position, which helps to expand the radiation area of the refrigerant in the first branch pipe 100 to the condenser 10 . Wherein, a plurality of connected pipe sections connected in sequence may be in a U-shape. In this way, it is possible to realize that the plurality of pipe sections are distributed in at least two rows. In addition, the U-shaped pipe sections connecting the two pipe sections are arranged obliquely, so that the pipe sections in adjacent rows are arranged outside.

The multiple sequentially connected pipe sections passing through the condenser 10 may be straight pipe sections, so that the pipe sections can be easily disassembled and assembled in the condenser 10 . In addition, it also facilitates processing.

A plurality of sequentially connected pipe sections can be arranged in parallel. In this way, on the one hand, it is convenient to assemble and disassemble, and on the other hand, it is convenient to process the condenser 10 . Optionally, some or all of the multiple sequentially connected pipe sections are arranged obliquely. Wherein, the specific inclination angle and the height of the inlet port and the outlet port are determined according to the actual situation. In this way, when the refrigerant enters the first branch pipeline 100 of the condenser 10, the flow of the refrigerant in the first branch pipeline 100 can be facilitated by a plurality of successively connected pipe sections arranged obliquely, and the flow of the refrigerant can be accelerated. flow.

Optionally, the evaporator 20 is provided with a second branch pipeline 200, the second branch pipeline 200 includes a liquid inlet 201 and at least two gas outlets 202, and the liquid inlet 201 is located in the middle section of the second branch pipeline 200 .

The liquid inlet 201 of the second branch pipeline 200 is located in the middle pipe section of the second branch pipeline 200. After the refrigerant enters the second branch pipeline 200 from the liquid inlet 201, the refrigerant flows to the two gas outlets 202 at the same time. This helps to improve the uniformity of refrigerant flow to the gas outlet 202.

Here "the liquid inlet 201 is located in the middle pipe section of the second branch pipeline 200" can be understood as: the liquid inlet 201 is located in the pipe section of the second branch pipeline 200, and this pipe section is not close to any gas outlet 202, and can be located in the second branch pipeline 200. The middle of the branch pipeline 200. It is also possible to divide the second branch pipeline 200 into three parts, for example, divide the second branch pipeline 200 into a first pipe section, a second pipe section and a third pipe section in sequence, wherein the two gas outlets 202 are respectively located at The first pipe section and the third pipe section, the liquid inlet 201 is located in the second pipe section.

In practical applications, the liquid inlet 201 can be connected to the middle pipe section of the second branch pipeline 200 through a micro-pipeline, so that it can prevent the refrigerant from entering the second branch pipeline 200 from the liquid inlet 201, due to the second The obstruction of the pipe wall of the branch pipe 200 weakens the flow velocity of the refrigerant. The micro-pipeline is bent or straight, so that the obstruction of the pipe wall of the second branch pipeline 200 to the refrigerant entering the second branch pipeline 200 from the liquid inlet 201 can be reduced.

Optionally, the liquid inlet 201 and the gas outlet 202 of the second branch pipeline 200 are located on the same side of the evaporator 20 .

The liquid inlet 201 and the gas outlet 202 through the second branch pipeline 200 are located on the same side of the evaporator 20, which not only helps to accommodate the connecting pipeline between the evaporator 20 and the external pipeline, but also facilitates the operation of the operator. The liquid inlet 201 and the gas outlet 202 of the second branch pipeline 200 and their connecting pipelines are disassembled and maintained. For example, after the evaporator 20 is installed, the connecting pipelines connected to the second branch pipeline 200 can be uniformly placed in the same space, which is convenient for storage and helps to maintain the overall appearance of the air conditioner.

Optionally, the second branch pipeline 200 includes: a first section pipeline 203 configured with a liquid inlet 201; a second section pipeline 204, one end communicates with one end of the first section pipeline 203, and the other end is an air outlet 202; the third section pipeline 205, one end communicates with the other end of the first section pipeline 203, and the other end is the gas outlet 202; wherein, the pipe section in the second section pipeline 204 and the pipe section in the third section pipeline 205 They are respectively arranged side by side with the pipe sections in the first section of pipeline 203 and misplaced.

Here, "the pipe sections in the second section of pipeline 204 and the pipe sections in the third section of pipeline 205 are respectively side by side with the pipe sections in the first section of pipeline 203" can be understood as: the second section of pipeline 204 is opposite to the first section of pipeline The road 203 is bent, and the third section of pipeline 205 is bent relative to the first section of pipeline 203 . In this way, the pipe sections in the second pipe line 204 and the pipe sections in the first pipe line 203 can be arranged side by side, and the pipe sections in the third pipe line 205 and the pipe sections in the first pipe line 203 can be arranged side by side.

By arranging the pipe sections in the second pipeline 204 side by side with the pipeline sections in the first pipeline 203, the gas outlet 202 can be made close to the liquid inlet 201, that is, the gas outlet 202 and the liquid inlet 201 are arranged as concentrated as possible . In this way, the connecting pipeline between the evaporator 20 and the outside can be conveniently disassembled by the operator.

By setting the pipe section in the third section pipeline 205 side by side with the pipe section in the first section pipeline 203, the gas outlet 202 at the end of the third section pipeline 205 can be close to the liquid inlet 201, that is, the gas outlet 202 is connected to the inlet port 201. The liquid ports 201 are arranged as concentratedly as possible. In this way, the connecting pipeline between the evaporator 20 and the outside can be conveniently disassembled by the operator.

Through the dislocation setting of the pipe section in the second section pipeline 204 and the pipe section in the first section pipeline 203 and the misplacement setting of the pipe section in the third section pipeline 205 and the pipe section in the first section pipeline 203, it is helpful to expand the first section pipeline. The radiation area of the refrigerant in the two-branch pipeline 200 to the evaporator 20 improves the heat dissipation efficiency.

Here, the dislocation setting in "the pipe section in the second section of pipeline 204 and the pipe section in the first section of pipeline 203" can be understood as the pipe section in the second section of pipeline 204 and the pipe section in the first section of pipeline 203 The pipe sections are arranged in two rows, and the pipe sections in the two rows are arranged at intervals.

Optionally, the gas outlet 202 of the second pipeline 204 and the gas outlet 202 of the third pipeline 205 are located on the same side of the first pipeline 203 . In this way, it is convenient for the operator to concentrate on operating the two air outlets 202 of the second branch pipeline 200 , for example, disassembling and assembling. In addition, the gas outlet 202 of the evaporator 20 communicates with the external connecting pipeline through a main gas outlet 202, and setting the two gas outlets 202 on the same side of the first section of the pipeline 203 can not only help save pipe materials, Moreover, it is also convenient for the operator to distinguish the two air outlets 202 of the second branch pipeline 200, so as to perform better maintenance and improve work efficiency.

Optionally, the gas outlet 202 of the second pipeline 204 and the gas outlet 202 of the third pipeline 205 are located on the same side of the evaporator 20 . In this way, the connecting pipelines between the second-section pipeline 204 and the third-section pipeline 205 and the external pipeline can be conveniently collected and processed.

Optionally, the diameter of the first branch pipeline 100 is smaller than the diameter of the second branch pipeline 200 .

Because the pipe diameter of the first branch pipeline 100 is smaller than the pipe diameter of the second branch pipeline 200, the charging amount of the R290 refrigerant can be greatly reduced, thereby reducing the potential safety hazard of the air conditioner. In addition, the distributed arrangement of the first branch pipeline 100 and the second branch pipeline 200 can also meet the cooling demand of the air conditioner and improve the overall energy efficiency of the air conditioner.

Optionally, the wall thickness of the first branch pipeline 100 is smaller than the wall thickness of the second branch pipeline 200 .

Through the wall thickness of the first branch pipeline 100 being smaller than the wall thickness of the second branch pipeline 200, in the case of a constant amount of refrigerant charge, the heat exchange efficiency between the condenser 10 and the air can be improved, thereby improving the performance of the air conditioner. The overall energy efficiency of the air conditioner meets the cooling demand of the air conditioner.
