Obviously, the described embodiments are only some but not all of the embodiments of the present application.

[0039] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0040] For the convenience of description, the embodiments of the present application use a coordinate system established by the first direction, the second direction and the third direction which are perpendicular to each other to describe the air conditioner. The arrangement direction of the condensing assembly is the first direction (as indicated by the arrow X in the figure), the upper and lower sides of the condensing assembly are the second direction (as indicated by the arrow Y in the figure), and the left and right sides of the condensing assembly are the third direction (as indicated by the arrow Z in the figure).

[0041] Embodiment 1:

[0042] Figure 1 A schematic diagram of an air conditioning equipment is provided for the embodiments of the present application. Referring to Figure 1 , a plurality of condensing assemblies 100 can be arranged on any one side of the heat exchange air duct 200 along the third direction, the plurality of condensing assemblies 100 can be arranged in sequence along the first direction, and the heat exchange air duct 200 can be provided with a plurality of air inlets 201 and a plurality of air outlets 202 arranged in sequence along the first direction. The heat exchange air duct 200 can be provided with an air blower 211 corresponding to each air inlet 201, and can be provided with an evaporator 221 corresponding to each air outlet 202, and the area of the plurality of air outlets 202 is greater than the area of the plurality of air inlets 201, so that the hot air in the machine room is introduced into the heat exchange air duct 200 by the air blower 211, the hot air flowing into the heat exchange air duct 200 exchanges heat with the evaporator 221 during flowing to the air outlet 202, and the cold air after heat exchange flows into the machine room again through the air outlet 202, so as to achieve the purpose of refrigeration in the machine room.

[0043] Further, in order to ensure the air flow uniformity of the cold air flowing into the machine room from the air outlet 202, the hot air in the machine room is quickly guided to the heat exchange air duct 200 by the air guide fan 211, and the air flow rate of the cold air flowing into the machine room is reduced by cooperating with the larger area of the air outlet 202, and the air flow uniformity of the cold air flowing into the machine room can be ensured, so as to avoid the hot spot in the machine room and ensure the purpose of fully and uniformly heat exchanging the machine room.

[0044] With reference to Figure 1 , the plurality of condensing assemblies 100 are arranged on one side of the heat exchange air duct 200 along the third direction, the plurality of air inlets 201 and the plurality of air outlets 202 of the heat exchange air duct 200 can be arranged on the other side of the heat exchange air duct 200 opposite to the plurality of condensing assemblies 100, and the plurality of air inlets 201 can be arranged above the plurality of air outlets 202, so that the hot air in the machine room can flow into the heat exchange air duct 200 from the air inlet 201 in time, thereby improving the overall heat exchange efficiency of the machine room.

[0045] In order to avoid that when the condensing assembly 100 is arranged on any one side of the heat exchange air duct 200 along the third direction, the overall structure of the air conditioning equipment is too large, resulting in that each structure of the air conditioning equipment needs to be disassembled and transported. The liquid storage tank 110 and the pump body 120 are arranged at the lower position of the condenser 101, and the width of the heat exchange air duct 200 along the third direction is appropriately adjusted, so that the overall structure of the air conditioning equipment can meet the road transportation requirements, realize the overall transportation of the air conditioning equipment, and the air inlets 201 and the air outlets 202 are arranged on the same side of the heat exchange air duct 200, thereby realizing the refrigeration effect of the hot air in the machine room.

[0046] Figure 2 For Figure 1 the top view of the air conditioning equipment is shown. With reference to Figure 1 and Figure 2 , the plurality of evaporators 221 and the plurality of compressors 222 in the heat exchange air duct 200 can be connected one by one with the plurality of condensing assemblies 100. Among them, the inflow end of the plurality of compressors 222 is connected with the outflow end of the plurality of evaporators 221 through a plurality of pipelines, the outflow end of the plurality of compressors 222 is connected with the inflow end of the plurality of pump bodies 120 through a plurality of first pipelines 223, the outflow end of the plurality of pump bodies 120 is connected with the inflow end of the plurality of liquid storage tanks 110 through a plurality of pipelines, the outflow end of the plurality of liquid storage tanks 110 is connected with the inflow end of the plurality of condensers 101 through a plurality of pipelines, and the outflow end of the plurality of condensers 101 is connected with the inflow end of the plurality of evaporators 221 through a plurality of second pipelines 224, so as to form a circulating pipeline of refrigerant.

[0047] In order to achieve the same heat exchange efficiency between the plurality of evaporators 221, the plurality of first pipes 223 and the plurality of second pipes 224 can be respectively arranged in parallel connection structure (not shown in the figure). So that the refrigerant of each condenser 101 can flow to each evaporator 221 uniformly, so as to ensure that the heat exchange efficiency between the plurality of evaporators 221 and the hot air in the heat exchange air duct 200 is as consistent as possible, thereby ensuring the uniformity of the cold air flowing into the machine room.

[0048] With reference to Figure 1 , the air inlet of the condenser 101 is arranged horizontally along the third direction, and the air outlet of the condenser 101 is arranged upwardly along the second direction, and the air outlet of the condenser 101 can be provided with an external fan 102. The external fan 102 is used to dissipate the heat generated by the condenser 101 during the cooling of the refrigerant, and to ensure the smooth progress of the condensation process.

[0049] Figure 5 is a top view of the V-shaped evaporator 221 in embodiment 1 of the present application. With reference to Figure 1 and Figure 5 , the evaporator 221 can adopt a linear evaporator 221 or a V-shaped evaporator 221. The linear evaporator 221 is arranged in a straight line, which has a larger heat exchange area to optimize the heat exchange efficiency of the refrigerant and air;

[0050] The V-shaped heat exchanger has the effect of uniform distribution of refrigerant, which can ensure the uniform flow of refrigerant in different parts of the evaporator 221, thereby improving the heat exchange effect of the evaporator 221, and further ensuring the uniformity of the cold air flowing into the machine room, avoiding the generation of hot spots in the machine room.

[0051] Embodiment 2:

[0052] Figure 3 is another schematic view of an air conditioning equipment provided in embodiment 2 of the present application. With reference to Figure 3 , the condenser 101 and the pump body 120 can be arranged above the heat exchange air duct 200. In order to avoid the overall height of the air conditioning equipment being too high, the height of the heat exchange air duct 200 can be limited to a lower height, so that when the condenser 101 and the pump body 120 are arranged above the heat exchange air duct 200, the overall size of the air conditioning equipment can meet the requirements of road transportation. In order to ensure the area of the air inlet 201 and the air outlet 202 of the heat exchange air duct 200, a plurality of air inlets 201 and a plurality of air outlets 202 are arranged on the heat exchange air duct 200 along the first direction, and the air inlets 201 and the air outlets 202 are arranged on the left and right sides of the heat exchange air duct 200 along the third direction, respectively, and the air inlets 201 and the air outlets 202 can be respectively provided with air guide fans 211 and evaporators 221, so that the hot air flowing through the heat exchange air duct 200 exchanges heat with the evaporators 221 to complete the refrigeration.

[0053] With reference to the above Figure 3 , the plurality of air inlets 201 and the plurality of air outlets 202 can be located on opposite sides of the heat exchange air duct 200 along the third direction, and the plurality of air inlets 201 and the plurality of air outlets 202 are arranged along the first direction. Among them, the area of the air outlet 202 is larger than the area of the air inlet 201, in order to avoid the area of the air outlet 202 being too small, resulting in the flow rate of the cold air flowing from the air outlet 202 to the machine room being too small, the plurality of air inlets 201 can be arrayed along the longitudinal direction of the second direction and along the horizontal direction of the first direction at the same time, so that each air outlet 202 corresponds to a plurality of air inlets 201, while ensuring the cooling effect of the evaporator 221 on the hot air in the heat exchange air duct 200, the cold air flowing into the machine room can maintain a certain flow rate, thereby realizing the cooling effect on the machine room.

[0054] Figure 4 To Figure 3 the top view of the air conditioning equipment is shown. Referring to Figure 3 and Figure 4 , after reducing the height of the heat exchange air duct 200 along the second direction, in order to fully utilize the overall space of the upper end surface of the heat exchange air duct 200, the plurality of liquid storage tanks 110 and the plurality of pump bodies 120 of the plurality of condensing assemblies 100 are arranged on the side of the plurality of condensing assemblies 100 along the third direction. So that the height of the condensing assembly 100 is further reduced.
