[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0033] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0034] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.
[0035] In the prior art, most of the main system components inside air conditioners are connected into a loop system through copper pipes. Figure 1As shown, in the existing air conditioning refrigerant loop system 500, the compressor 501, the gas-liquid separator 503, the four-way valve 502 and other components are all welded through a large section of irregular copper tube 504 to achieve the circulation of refrigerant. Since it is necessary to consider factors such as the difficulty of pipeline processing, the direction of the pipeline, and the gap between the pipelines, it generally takes up a large space, and the layout space on the pipeline side of the air conditioner is limited. The copper tube 504 is welded, and welding is required during the processing, which is dangerous. In addition, the copper tube 504 has poor rigidity, which is prone to stress concentration, fatigue fracture, and amplification of the noise of the compressor 501.
[0036] In order to solve the technical problem that the copper tube 504 in the existing air-conditioning refrigerant loop system 500 is difficult to process and that a large space is occupied due to the need to consider the pipeline gap, the present application provides an assembled piping system and an air conditioner, which can realize the circulation and flow of refrigerant in the air conditioner under cooling or heating conditions, thereby greatly reducing the space occupied by the assembled piping system.
[0037] Figure 2 An assembly piping system 110 provided in an embodiment of the present application is arranged on an air conditioner 100, and the assembly piping system 110 includes a first connection module 1, a second connection module 2, a third connection module 3 and a fourth connection module 4 arranged in sequence, wherein the first connection module 1 includes a first connection plate 11, and the first connection plate 11 is used to connect the compressor 120 and the exhaust muffler 130; the second connection module 2 includes a second connection plate 21 and a third connection plate 22, and the third connection plate 22 is used to connect the four-way valve 140; the third connection module 3 includes a fourth connection plate 31, a fifth connection plate 32 and a sixth connection plate 33, the fourth connection plate 31 is used to connect the condenser 150, the fifth connection plate 32 is used to connect the filter 160 and the gas-liquid separator 170, and the sixth connection plate 33 is used to connect the first valve 191; the fourth connection module 4 includes a seventh connection plate 41 and an eighth connection plate 42, the seventh connection plate 41 is used to connect the expansion valve 180, and the eighth connection plate 42 is used to connect the second valve 192.
[0038] It is understandable that by assembling the first connection module 1, the second connection module 2, the third connection module 3 and the fourth connection module 4 to form a pipeline system, the circulation and flow of the refrigerant of the air conditioner 100 under the cooling condition or the heating condition can be realized, and the multiple irregular copper tubes are changed into multiple regular connection plates, without considering the gap between the pipelines, which greatly reduces the occupied space of the assembled pipeline system 110, and can be placed horizontally or vertically on the pipeline side of the air conditioner 100, thereby solving the problem of insufficient space for the pipeline layout of the air conditioner 100. Compared with the prior art, no welding is required during the assembly process, which improves safety, and avoids stress concentration, fatigue fracture, and amplification of the noise of the compressor 120 caused by the poor rigidity of the copper tube. After the interfaces connecting the various connection plates with the expansion valve 180, the four-way valve 140 and other components are made into standard interfaces, the modularization and standardization of the pipeline system can be realized, which can greatly reduce the number of materials and reduce the procurement cost.
[0039] Optionally, each connecting plate in the first connecting module 1, the second connecting module 2, the third connecting module 3 and the fourth connecting module 4 can be made of stainless steel, which can greatly reduce material costs and manufacturing costs compared to the use of copper tubes to connect components in a traditional loop system.
