[0042] Further, as shown in Figure 4 the production mode of the pipe is changed, the pipeline parts are split and increased, the air-cooled outdoor unit and the fluorine pump module 2 outdoor unit can be realized on one unit. Firstly, the condenser liquid outlet pipe 34 is processed by using the two sections of the condenser liquid outlet pipe 341 and the condenser liquid outlet pipe 342, the two sections of the pipeline are connected by using the first three-way valve 51, the other outlet of the first three-way valve 51 is connected to the connecting pipe 35, the other end of the connecting pipe 35 is connected to the second three-way valve 52, and the other two ends of the second three-way valve 52 are respectively connected to the first liquid outlet section 341 and the first liquid outlet section 342 split from the liquid outlet pipe 34. By controlling the on-off of the second three-way valve 52 and the first three-way valve 51, the flow direction of the refrigerant can be controlled.

[0043] When the fluorine pump module 2 unit needs to be used, the path of the first section 311 to the connecting pipe 35 through the first three-way valve 51 and the path of the connecting pipe 35 to the liquid outlet pipe 34 through the second three-way valve 52 are closed. The liquefied refrigerant flows out from the condenser, enters the first connecting pipe 31, flows into the first connecting pipe 31 through the first three-way valve 51, enters the liquid storage tank 12, continues to flow into the second connecting pipe 32 from the liquid storage tank 12, enters the fluorine pump 21, flows out from the liquid outlet pipe 34 connected to the fluorine pump 21, flows to the liquid outlet pipe 34 through the second three-way valve 52, and then flows out to the liquid outlet valve.

[0044] When the air-cooled module 1 is needed to be used, the path of the first connecting pipe 31 flowing to the first connecting pipe 31 via the first three-way valve 51 and the path of the first connecting pipe 31 flowing to the liquid outlet pipe 34 via the second three-way valve 52 are closed, the liquid refrigerant flows from the first connecting pipe 31 to the second connecting pipe 32 directly via the first three-way valve 51, and then flows from the second connecting pipe 32 to the liquid outlet pipe 34 directly via the second three-way valve 52, and then flows out from the liquid outlet valve, and the step of the refrigerant passing through the fluorine pump module 2 is omitted.

[0045] The application also discloses some embodiments that the air conditioner outdoor unit further comprises a pipe fixing support 4.

[0046] When the air conditioner outdoor unit further comprises the first connecting pipe 31, the first connecting pipe 31 is fixed to the fixing support 4.

[0047] The application also discloses some embodiments that when the air conditioner outdoor unit further comprises the third connecting pipe 33, the third connecting pipe 33 is fixed to the fixing support 4.

[0048] The application also discloses some embodiments that when the air conditioner outdoor unit further comprises the liquid outlet pipe 34, the liquid outlet pipe 34 is fixed to the fixing support 4. All the pipes in the application are fixed to the fixing support 4, and the third connecting pipe 33 is a bypass pipe; the application changes the connection path of the bypass pipe, so that the bypass pipe is directly fixed to the fixing support 4 of the original inlet pipe 36 and the liquid outlet pipe 34, and the fixing of multiple pipe elements is completed on one fixing support 4, thereby generating a multifunctional fixing support 4, simplifying the production and installation process, and improving the space utilization. The pipe structure and its accessories in the prior art have low universality, the same part needs to be processed repeatedly, occupies redundant space and needs a separate support for fixing, causing meaningless waste of production materials and production time. The second connecting pipe 32 can be fixed to the fixing support 4. The fixing support 4 comprises a first support and a second support, the third connecting pipe 33, the liquid outlet pipe 34 and the inlet pipe 36 are fixed to the first support, and the first connecting pipe 31 is fixed to the second support.

[0049] The outdoor unit of the application comprises a left side plate assembly 61, a right side plate assembly 62, a fluorine pump 21 support, a stand assembly 68, a front door plate 64, a fan assembly 13, a top cover 63, a base, a bottom plate assembly 67, an electrical box 71 assembly 7, a fluorine pump module 2, an upper cover plate 65, and a rear cover plate assembly 66. Of course, there are more details on the actual product, such as sponge, fixing screws, rivets, sealing strips, etc., but it does not mean that the production of the unit does not require these features. The electrical box 71 assembly 7 comprises an electrical box 71 and a box cover 72. The stand assembly 68 and the base are fixed by screws and other fasteners. The front and rear side plates are fixed on the base by screws. Similarly, the front door plate 64 is fixed on the unit rack by screws. The bottom plate and its accessories are fixed on the base by screws. The fluorine pump support 22 is fixed on the base by screws, and the fluorine pump module 2 is fixed on the fluorine pump support 22 by screws.

[0050] Further, in the fluorine pump module 2, the inlet pipe 36, the outlet pipe 34, and the bypass pipe and their required pipe clamps are fixed on the multifunctional support by screws. The inlet valve and the outlet valve are fixed on another multifunctional support. It should be noted that the inlet valve and the outlet valve and their supporting pipelines need to be pulled apart a certain distance when fixed, otherwise the temperature difference between the two pipes during operation will affect each other. The liquid storage tank 12 and the fluorine pump 21 are fixed on the support by screws and connected by the second connecting pipe 32. The fluorine pump module 2 is installed in the internal space surrounded by the condenser assembly of the outdoor unit of the air conditioner, making full use of the blank space of this part of the space. The refrigerant enters the inlet valve, enters the inlet pipe 36 connected to the inlet valve, and after flowing out of the condenser, the liquefied refrigerant enters the liquid storage tank 12 through the first connecting pipe 31, then enters the fluorine pump 21 from the liquid storage tank 12 through the second connecting pipe 32, and finally flows out from the outlet pipe 34. It should be noted that when the liquid outlet is small, the refrigerant flowing out of the condenser directly enters the outlet pipe 34 through the first connecting pipe 31 and the third connecting pipe 33, and then directly enters the fluorine pump 21.

[0051] The flow path 1 of the application: the liquefied refrigerant flows out of the condenser to the first connecting pipe 31, flows into the liquid storage tank 12 from the first connecting pipe 31, flows into the second connecting pipe 32 from the liquid storage tank 12, flows into the fluorine pump 21 from the second connecting pipe 32, flows into the outlet pipe 34 from the fluorine pump 21, and then flows out from the outlet pipe 34.

[0052] The flow path 2 of the application: the liquefied refrigerant flows out of the condenser to the first section 311, flows into the connecting pipe 35 from the first section 311, and flows into the first outlet section 341 from the connecting pipe 35.

[0053] The air inlet pipe 36 is connected to the air inlet valve and extends upward to the top end of the heat exchanger 11, and then is bent, and then is connected to the heat exchanger 11 again by the bending. When the unit is stopped, the liquid refrigerant in the heat exchanger 11 can flow back. The height is increased to prevent the liquid refrigerant from flowing back into the air inlet pipe 36. The liquid refrigerant can be reduced to the greatest extent. The third connecting pipe 33 connects the second connecting pipe 32 and the first connecting pipe 31. The first connecting pipe 31 connects the heat exchanger 11 and the liquid storage tank 12. The second connecting pipe 32 connects the liquid storage tank 12 and the fluorine pump 21.

[0054] The fluorine pump module 2 is composed of the newly added liquid storage tank 12, the second connecting pipe 32, the fluorine pump 21 and the bypass pipe. In order to make full use of the internal space of the outdoor unit, the bypass pipe path is changed, and the bypass pipe is fixed on the same bracket with the air inlet pipe 36 and the liquid outlet pipe 34, so as to maximize the function of the bracket and create a multifunctional bracket.

[0055] In the prior art, in order to be fixed to the machine body, a separate bracket is used to connect the bypass pipe and the chassis. The connecting pipe 35 path is complex and occupies a large space. The original bypass pipe path is complex and occupies a large space. At the same time, the separate bypass pipe fixing bracket 4 also consumes production materials and production time. The third connecting pipe 33, i.e. the bypass pipe, is used in the present application. By changing the bypass pipe path, the bypass pipe is successfully fixed on the bracket of the air inlet pipe 36 and the liquid outlet pipe 34. The same effect of fixing the bypass pipe on the machine body can be achieved, a separate bracket is saved, the spare space below the air inlet pipe 36 and the liquid outlet valve liquid outlet pipe 34 is fully utilized, a lot of space originally occupied by the bypass pipe is saved, and the processing and installation cost of a bracket is reduced.

[0056] The present application provides a one-machine two-use idea, i.e. changing the layout and installation mode of the outdoor unit pipe of the air conditioner, controlling the flow direction of the refrigerant through two three-way valves, and realizing the switching of two air conditioners. The general rate of the unit can be improved, and the switching use of the air conditioner in the air-cooled modular machine room and the fluorine pump heat pipe machine room can be realized in special cases.

[0057] According to another aspect of the present application, an air conditioner is provided, comprising the above-mentioned outdoor unit of the air conditioner. The air conditioner of the present application is a fluorine pump heat pipe machine room air conditioner structure.

[0058] Those skilled in the art can easily understand that the above-mentioned advantageous modes can be freely combined and superimposed without conflict.

[0059] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application. The above is merely the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principle of the present application, a number of improvements and variations can be made, these improvements and variations should also be considered as the protection scope of the present application.
