[0020] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0021] The mobile split air conditioner provided by the embodiment of the present application includes a first shell and a second shell, an evaporator and a compressor are arranged in the first shell, and the evaporator and the compressor are connected through a first connecting pipe; the first shell and the second shell are detachably connected; a first condensation structure, a second condensation structure and a first fan are arranged in the second shell; the first condensation structure is connected to the compressor through the second connecting pipe; the first condensation structure and the second condensation structure are connected through a third connecting pipe; the second condensation structure is connected to the evaporator through a fourth connecting pipe, a capillary is arranged on the fourth connecting pipe, and the first fan is arranged corresponding to the second condensation structure; wherein the volume of the second condensation structure is greater than the volume of the first condensation structure. In this way, the first shell and the second shell are detachably connected, which can achieve the purpose of being easy to carry and split use. At the same time, in the refrigeration circuit using the capillary as the interception method, the first condensation structure is added between the second condensation structure and the compressor, and the first condensation structure is independent of the second condensation structure, so that the refrigerant coming out of the compressor exhaust port first enters the first condensation structure for cooling, and then enters the second condensation structure for heat exchange condensation, thereby reducing the pressure and temperature of the system refrigerant flow path, and the refrigeration outlet temperature is lower, which can also enable the mobile split air conditioner to operate at a more severe ambient temperature.

[0031] 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.

[0034] The present application provides a mobile split air conditioner, which can reduce the pressure and temperature of the system refrigerant flow path. The lower refrigeration air outlet temperature can also enable the mobile split air conditioner to operate in more severe ambient temperatures.

[0035] Figures 1 to 3 A mobile split air conditioner provided for an embodiment of the present application includes a first shell 1 and a second shell 2, an evaporator 11 and a compressor 12 are provided in the first shell 1, and the evaporator 11 and the compressor 12 are connected via a first connecting pipe 13; the first shell 1 and the second shell 2 are detachably connected; a first condensation structure 21, a second condensation structure 22 and a first fan 23 are provided in the second shell 2; the first condensation structure 21 is connected to the compressor 12 via a second connecting pipe 24; the first condensation structure 21 and the second condensation structure 22 are connected via a third connecting pipe 25; the second condensation structure 22 is connected to the evaporator 11 via a fourth connecting pipe 26, a capillary 27 is provided on the fourth connecting pipe 26, and the first fan 23 is arranged corresponding to the second condensation structure 22; wherein, the volume of the second condensation structure 22 is greater than the volume of the first condensation structure 21.

[0036] It can be understood that the first shell 1 and the second shell 2 are detachably connected, which can achieve the purpose of being easy to carry and use separately. For example, when the user needs to use it in an outdoor tent, the first shell 1 and the second shell 2 can be separated, the first shell 1 is placed inside the tent, and the second shell 2 is placed outside the tent. Space for the second connecting tube and the fourth connecting tube to pass through can be left at the zipper door of the tent. When not in use, the first shell 1 and the second shell 2 can be connected to form a whole, which is convenient for carrying and storage.

[0037] In the present application, in the refrigeration circuit using the capillary tube 27 as the interception method, a first condensation structure 21 is added between the second condensation structure 22 and the compressor 12, and the first condensation structure 21 is independent of the second condensation structure 22. In this way, the refrigerant coming out of the exhaust port of the compressor 12 first enters the first condensation structure 21 for cooling, and then enters the second condensation structure 22 for heat exchange and condensation, thereby reducing the pressure and temperature of the system refrigerant flow path. The lower refrigeration outlet temperature can also enable the mobile split air conditioner to operate at a more severe ambient temperature. Among them, the volume of the second condensation structure 22 is larger than that of the first condensation structure 21. This is because the first fan 23 corresponds to the second condensation structure 22, and the main heat dissipation in the second shell 2 is still at the second condensation structure 22. The larger the volume of the second condensation structure 22, the higher the energy efficiency.

[0038] In the present application, the first fan 23 is provided corresponding to the second condensation structure 22, and the first condensation structure 21 is not provided with a heat dissipation fan, but uses natural convection to dissipate heat, which can save costs and reduce internal space.

[0039] It should be noted that, in order to facilitate display of the internal structure of the second shell 2, only the bottom shell structure of the second shell 2 is shown in the drawings.

[0040] In the technical solution of this embodiment, the ratio of the volume of the second condensation structure 22 to the volume of the first condensation structure 21 is greater than 2.

[0041] It is understandable that the volume of the second condensation structure 22 is at least twice that of the first condensation structure 21, so that the second condensation structure 22 mainly bears the heat dissipation function and obtains higher energy efficiency. When the volume ratio of the second condensation structure 22 to the first condensation structure 21 is less than 2, since the first condensation structure 21 relies on natural convection to dissipate heat, the air conditioner may have poor heat dissipation effect and low energy efficiency.

[0042] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the first condensation structure 21 includes two first condensers 211 , the two first condensers 211 are respectively arranged on both sides of the first fan 23 , and the two first condensers 211 are connected by a fifth connecting pipe 28 .

[0043] It can be understood that by configuring the first condensation structure 21 as two first condensers 211 connected in series and respectively located on both sides of the first fan 23, on the one hand, the purpose of rational use of space is achieved and the volume of the air conditioner is ensured to be small as soon as possible for easy carrying; on the other hand, the two first condensers 211 are far apart and will not affect each other during natural convection heat dissipation, and both can improve the natural convection heat dissipation effect under the influence of the first fan 23.

[0044] The fifth connecting pipeline 28 may be a copper pipe.

[0045] In the present application, the compressor 12 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous state, and sends it to the first condenser 211 for primary cooling, and then sends it to the second condensation structure 22 for secondary heat exchange condensation. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant. The medium-temperature liquid refrigerant is throttled and depressurized into a low-temperature and low-pressure gas-liquid mixture through the capillary 27. After that, the low-temperature and low-pressure gas-liquid mixture passes through the evaporator 11 to absorb the heat in the air and vaporize, becoming a gaseous state. The evaporator 11 absorbs the heat in the air, which will cause the pipe temperature of the evaporator 11 to be low. When the air passes through the evaporator 11, heat exchange will occur and the temperature will drop, thereby realizing air conditioning refrigeration; afterwards, the gaseous refrigerant returns to the compressor 12 for further compression, and continues to circulate for refrigeration. Heating can be achieved by making the flow direction of the refrigerant in the condenser and the evaporator 11 opposite to that during refrigeration.

[0046] like Figure 1 As shown, in the technical solution of this embodiment, the fifth connecting pipeline 28 is located above the first fan 23 .

[0047] It can be understood that the fifth connecting pipe 28 connecting the two first condensers 211 is arranged above the first fan 23 to facilitate assembly and maintenance.

[0048] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the first fan 23 includes a fan fixing frame 231 and a fan body 232. The fan fixing frame 231 is connected to the second shell 2, and the fan fixing frame 231 is a frame structure. The fan fixing frame 231 is provided with a mounting hole; the fan fixing frame 231 is arranged parallel to the second condensation structure 22; the two first condensers 211 are respectively located on both sides of the fan fixing frame 231; the fan body 232 is installed in the mounting hole and is arranged corresponding to the second condensation structure 22.

[0049] It is understandable that the fan fixing bracket 231 provides installation support for the fan body 232 , and heat dissipation of the second condensation structure 22 is achieved through the fan body 232 arranged corresponding to the second condensation structure 22 .

[0050] To ensure that the separation and connection of the first shell 1 and the second shell 2 can be carried out smoothly, in the technical solution of this embodiment, the second connecting pipeline 24 and the fourth connecting pipeline 26 are both hoses.

[0051] like Figures 1 to 3 As shown, in the technical solution of this embodiment, both the first condensation structure 21 and the second condensation structure 22 adopt fin-type heat exchangers.

[0052] It can be understood that the finned heat exchanger has good and stable heat transfer performance, small resistance to air passing through, steam or hot water or coolant flows through the steel pipe, and the heat is transferred to the air passing through the fins through the fins tightly wrapped around the steel pipe, thereby achieving the effect of heating and cooling the air.

[0053] In the technical solution of this embodiment, a handle is provided on the first shell 1.

[0054] It can be understood that the design of the handle makes it easy to move the mobile split air conditioner, and the handle is provided on the first shell 1 to facilitate the movement of the first shell 1.

[0055] In the technical solution of this embodiment, a handle is provided on the second shell 2.

[0056] It is understandable that a handle is provided on the second shell 2 to facilitate the movement of the second shell 2 .

[0057] like Figure 1 As shown, in the technical solution of this embodiment, the first housing 1 is provided with an operation panel 15. It can be understood that it is convenient for users to operate.

[0058] In the technical solution of this embodiment, the first housing 1 is also provided with an indicator light.

[0059] It should be noted that remote control operation can also be performed through a remote controller or a mobile terminal.

[0060] like Figure 3 As shown, in the technical solution of this embodiment, a second fan 14 is further provided in the first housing 1, and the second fan 14 is provided corresponding to the evaporator 11. Thus, the provision of the second fan 14 can improve the heat exchange efficiency of the evaporator 11.

[0061] like Figure 1 As shown, the first shell 1 is also provided with a drain pipe 16 to discharge condensed water generated during the heat exchange process.
