The air conditioning system mainly comprises a compressor forming a refrigerant main loop, an indoor heat exchanger, a throttling component and an outdoor heat exchanger, and air with proper temperature can be provided for an indoor space along with the phase change of the refrigerant through the circulating flow of the refrigerant in the loop formed by the compressor, a condenser, the throttling component, an evaporator and the compressor. For example, in the case where the air conditioning system is in a heating mode, the indoor heat exchanger functions as a condenser for distributing heat, and in the case where the air conditioning system is in a cooling mode, the indoor heat exchanger functions as an evaporator for distributing cooling.

Typically, the outdoor heat exchanger and the compressor are provided in an air conditioning outdoor unit. The outdoor heat exchanger is provided with a fan. In the case where the air conditioner is in the cooling mode, it is necessary to ensure that the outdoor heat exchanger as the condenser has good heat dissipation performance. Specifically, the heat of the surface of the condenser can be timely carried away by circularly introducing, flowing and discharging air in the external environment into the outdoor heat exchanger under the action of the fan, so that the heat radiation performance of the outdoor unit of the air conditioner is ensured.

In order to secure the heat radiation performance of the outdoor unit of the air conditioner, the axial flow fan should have a suitable distance from the outdoor heat exchanger. In order to ensure the heat dissipation performance of the outdoor unit of an air conditioner, the axial flow fan and the air ring need to be moved away from each other, and one of the results of the outward movement is that the air ring protrudes out of the casing. This results in the outdoor air conditioner needing to be sized for the windband during transport, thereby increasing transport costs.

Accordingly, there is a need in the art for a new solution to the above problems.

The air conditioner mainly comprises a compressor forming a refrigerant main loop, an indoor heat exchanger, an outdoor heat exchanger, a throttling component (such as a capillary tube, an electronic expansion valve and the like) and a four-way valve, wherein the compressor and the outdoor heat exchanger are communicated by switching the four-way valve, so that the air conditioning system has a conventional refrigeration mode and a heating mode, and cold/heat can be distributed to the surface of the indoor heat exchanger along with the phase change of the refrigerant through the circulating flow of the refrigerant in a loop formed by the compressor, the condenser, the throttling component, the evaporator and the compressor. Specifically, the method comprises the following steps: when the refrigerant circulates along the circuit of the compressor → the indoor heat exchanger → the outdoor heat exchanger → the compressor, the air conditioning system is in a heating cycle. Namely: under the condition that the air conditioning system is in a heating mode, the indoor heat exchanger is used as a condenser for distributing heat; when the refrigerant circulates along the circuit of the compressor → the outdoor heat exchanger → the indoor heat exchanger → the compressor, the air conditioning system is in a refrigeration cycle. Namely: in the case of an air conditioning system in a cooling mode, the indoor heat exchanger acts as an evaporator for distributing cooling energy.

Air conditioners generally comprise an outdoor part and an indoor part, which are integrated in the same casing for existing models (such as window air conditioners, etc.). For most models, the outdoor part and the indoor part are of a split structure, wherein the outdoor part is called an air conditioner outdoor unit, and the indoor part is called an air conditioner indoor unit, and the outdoor part and the indoor part are connected through a pipeline.

Air conditioners of a split type structure generally include a cabinet type air conditioner, a wall-mounted air conditioner, and a built-in type air conditioner. Taking a hanging machine as an example, the back of a shell of an indoor air conditioner of an air conditioner is usually fixedly arranged on a wall of an indoor space, the shell is provided with an air supply outlet and an air return inlet (such as bottom air supply and bottom air return), an indoor heat exchanger, an indoor fan, a water receiving disc, an electric cabinet and the like are mainly arranged in the shell, the air conditioner is in a refrigeration/heating circulation process, under the action of the indoor fan, a part of air in the indoor space is pumped into the shell through the air return inlet and exchanges heat with the surface of the indoor heat exchanger, the temperature of the part of air is reduced/increased, the part of air with the reduced temperature is sent into the indoor space again through the air supply outlet, and the process is repeated, so that cold/heat generated by phase change of a refrigerant and circulation flow can be gradually released into the indoor space. The surface of the condenser generates condensed water while heat is transferred to the indoor space. In order to ensure the sustainability of the refrigeration, it is necessary to discharge the condensed water to the outdoor side in time. The water pan arranged below the indoor heat exchanger is mainly used for collecting condensed water generated on the surface of the indoor heat exchanger, the shell is usually provided with a water drainage joint in butt joint with the water pan, the water drainage joint is provided with a water drainage pipe, the upstream side of the water drainage pipe is matched and connected with the water drainage joint, the downstream side of the water drainage pipe extends out of the outdoor side, the condensed water collected by the water pan is discharged in time through the water drainage pipe, and the operation sustainability of the air conditioner is guaranteed.

Still taking the air conditioner with the split structure as an example, as shown in fig. 1 to 4, the outdoor unit 100 of the air conditioner mainly includes a casing 1, a front panel 11 of the casing has a mounting hole, a mounting ring 12 is disposed at the mounting hole, and a plurality of movable ends 13 (for example, 6) are disposed on an inner wall of the mounting ring along a circumferential direction. An outdoor fan (such as an axial flow fan 2) and an L-shaped outdoor heat exchanger 3 (generally called a condenser) surrounding the outer side of the axial flow fan are arranged in the shell. The circumference outside of axial fan encloses and is provided with solar or lunar halo 4, and the axial front side of solar or lunar halo is provided with radiator grille 5. The heat dissipation principle of the axial flow fan to the outdoor heat exchanger is as follows: the air of the external environment is guided to enter the shell through the rotation of the axial flow fan and is discharged out of the shell after the air exchanges heat with the surface of the outdoor heat exchanger. The circulation can timely take away the heat on the outdoor heat exchange surface, thereby ensuring the sustainability of the operation of the air conditioner.

In consideration of convenience of transportation, the conventional outdoor unit generally has a louver disposed in a casing of the outdoor unit, which may affect heat dissipation performance of the outdoor unit. Particularly, the axial flow fan is adaptive to the position of the air ring, the axial flow fan is inevitably closer to the outdoor heat exchanger, and when the axial flow fan is too close to the outdoor heat exchanger, the central shaft of the axial flow fan can cause the uneven flow field of air, so that the guiding degree of the axial flow fan to the air is influenced, and the heat dissipation effect of the outdoor heat exchanger is further influenced. In view of this, the present invention makes the wind circle movable relative to the installation circle, specifically, the outer wall of the wind circle is provided with a track end corresponding to a plurality of movable ends, the track end is provided with a track allowing the movable end 13 to move freely, referring to fig. 4 and according to the orientation in fig. 4, in a specific embodiment, the track is a vertical part 60 distributed along the direction in which the air of the external environment enters the housing (i.e. the left-right direction in fig. 4), the vertical part extends along the same circumferential direction of the installation hole (i.e. the direction from bottom to top in fig. 4) and is provided with a first transverse part 61 and a second transverse part 62 which are substantially identical in structure and are used as a limit structure, the vertical part, the first transverse part and the second transverse part are strip-shaped grooves, the first transverse part is located at the left position of the vertical part, the second transverse part is located at the right end of the vertical part, the width of the (first, second) transverse portion is slightly smaller than the vertical portion so as to be able to secure the movable end into the respective transverse portion when the movable end enters the (first, second) transverse portion. In this way, the position of the windband relative to the front panel of the housing can be adjusted by switching the movable end between the (first, second) lateral portions after the movable end has entered the rail via the left end of the rail. Specifically, the method comprises the following steps:

when the outdoor unit of the air conditioner is in a transportation state, the built-in air ring can be realized by applying external force to the air ring to enable the air ring to rotate clockwise, push left and rotate anticlockwise, so that the packaging thickness is saved, and the transportation cost is reduced.

When the outdoor unit of the air conditioner is installed to the position corresponding to the running state, the outer arrangement of the air ring can be realized by applying external force to the air ring to enable the air ring to rotate clockwise, pull rightwards and rotate anticlockwise, and meanwhile, the position of the fan is adjusted adaptively, so that a sufficient distance can be ensured between the fan and the outdoor heat exchanger, and the optimal heat dissipation effect can be achieved.

Therefore, the utility model discloses a required packing dimension of air condensing units of air conditioner directly can according to the casing is confirmed, consequently can obviously save packing size cost, reduce the cost of transportation. And, in practical application, the utility model discloses an air conditioner makes the position of axial fan and leeway no longer receive the restriction of factors such as product structure itself and size, consequently under the prerequisite that the leeway can move about, can guarantee to have abundant distance between axial fan and the radiator to the heat dispersion of air conditioner has been improved.

In fact, the user can flexibly adjust the related structure according to the situation such as practical application scene, for example, the mounting ring is integrally arranged at the position of the shell corresponding to the mounting hole.

The technical solutions of the present invention have been described so far in connection with preferred embodiments, but it is obvious to those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
