Alternatively, the reversing assembly 3 may be a four-way reversing valve.
When the first valve port 31 is communicated with the second valve port 32 and the fourth valve port 34 is communicated with the third valve port 33, the air conditioning system 100 is in a cooling mode (the direction a in fig. 1 is the circulation direction of the refrigerant in the cooling mode), the refrigerant is compressed by the compressor 1, discharged from the exhaust port 11, sequentially flows through the first valve port 31, the second valve port 32, the outdoor heat exchanger 4, the throttle assembly, the indoor heat exchanger 5, the third valve port 33 and the fourth valve port 34, and finally enters the compressor 1 through the return air port 12 to be compressed again. When the refrigerant flows through the outdoor heat exchanger 4, the refrigerant is condensed to release heat; when the refrigerant flows through the indoor heat exchanger 5, the refrigerant evaporates to absorb heat, so that the refrigeration of the air conditioning system 100 can be realized.

Therefore, the throttling component is arranged to comprise the capillaries which are connected in series, and the flow areas of at least two capillaries are different, so that when the refrigerant circulates along different directions (refer to the direction a and the direction b in fig. 1), the total throttling effect generated by the throttling component is different, and the requirements of cooling/heating on different refrigerant flow rates are met. Moreover, the capillary tube has no moving part and relatively large inner diameter (the inner diameter of the capillary tube can be made larger than that of a throttle valve and an expansion valve under the condition of the same throttling effect), so that the requirements of refrigeration/heating on different refrigerant flow rates can be met, and the running stability and reliability of the air conditioning system 100 can be improved.

According to some embodiments of the present invention, referring to fig. 1, the throttling assembly comprises two capillaries connected in series, the flow areas of the two capillaries being different. Therefore, the requirement that the total throttling effect generated by the throttling assembly is different is met, the requirements of refrigeration/heating on different refrigerant flow rates are met, and meanwhile the number of parts of the throttling assembly is small and the structure is simple.
According to some optional embodiments of the present invention, each capillary is a circular tube, and the inner diameters of the two capillaries are different. Therefore, when the capillary tube is a circular tube, the different flow areas of the two capillary tubes can be conveniently realized by making the inner diameters of the two capillary tubes different, and the structure of the capillary tube is simple.
Optionally, the absolute value of the difference between the inner diameters of the two capillaries is a, and a satisfies: a is more than or equal to 0.1mm and less than or equal to 0.3 mm. Therefore, the total throttling effect generated by the throttling assembly is different, so that the refrigerating/heating effect can be ensured while the requirements of refrigerating/heating on different refrigerant flow rates are met.

Therefore, the refrigerating/heating effect can be ensured while the requirement that the total throttling effect generated by the throttling component is different, and the performance of the air conditioning system 100 can be further improved according to the matching of the inner diameter and the length of the two capillary tubes.
According to some optional embodiments of the present invention, referring to fig. 1, the two capillaries are a first capillary 61 and a second capillary 62, respectively, the first end of the first capillary 61 is connected to the second end of the outdoor heat exchanger 4, the second end of the first capillary 61 is connected to the first end of the second capillary 62, the second end of the second capillary 62 is connected to the second end of the indoor heat exchanger 5, and the flow area of the first capillary 61 is larger than that of the second capillary 62. Therefore, the requirement that the total throttling effect generated by the throttling assembly is different is met, so that the requirement that the refrigerant flow is different in cooling/heating is met, meanwhile, the refrigerant flow in the cooling mode is larger than the refrigerant flow in the heating mode, and the cooling/heating requirement of the air conditioning system 100 is better met.
Further, referring to fig. 1, the air conditioning system 100 includes: and the electronic control heat dissipation assembly 7 comprises an electronic control assembly and a heat dissipation assembly for dissipating heat of the electronic control assembly, and the heat dissipation assembly is connected in series between the second end of the first capillary tube 61 and the first end of the second capillary tube 62.

Moreover, since the flow area of the first capillary tube 61 is larger than that of the second capillary tube 62, when the air conditioning system 100 is used for cooling, the condensation risk of the electric control assembly can be reduced while the electric control assembly is cooled by the refrigerant. Optionally, the electronic control component may be an electronic control component of an outdoor unit of the air conditioning system 100, so that the outdoor unit of the air conditioning system 100 can still perform normal cooling operation under a high-temperature working condition.
For example, in a specific example of the present invention, the air conditioning system 100 includes the above-mentioned compressor 1, the reversing component 3, the outdoor heat exchanger 4, the indoor heat exchange, the throttling component, the liquid reservoir 2 and the electronic control heat dissipation component 7, and the electronic control component of the electronic control heat dissipation component 7 is an electronic control component of an outdoor unit of the air conditioning system 100.

The first capillary 61 and the second capillary 62 are both circular copper tubes, the inner diameter Φ 1 of the first capillary 61 is 1.5mm, the length L1 of the first capillary 61 is 700mm, the inner diameter Φ 2 of the second capillary 62 is 1.3mm, and the length L2 of the first capillary 61 is 500 mm.
When the refrigerant circulates along the direction a in fig. 1, the air conditioning system 100 is in a cooling mode, when the ambient temperature of the outdoor unit of the air conditioning system 100 is 60 ℃, the temperature of the refrigerant at the outlet of the outdoor heat exchanger 4 is 63 ℃, the temperature of the refrigerant flowing out of the outdoor heat exchanger 4 after being slightly throttled by the first capillary tube 61 may still be 63 ℃, or may be slightly lower, the refrigerant at the temperature flows through the heat dissipation assembly to dissipate heat of the electronic control assembly (for example, the temperature of the electronic control assembly is 70 ℃), and the refrigerant flowing through the heat dissipation assembly can take away a part of heat generated by the electronic control assembly, so that the electronic control assembly is in a temperature region where the electronic control assembly can reliably operate. After flowing out of the heat dissipation assembly, the refrigerant generates a strong throttling effect through the second capillary tube 62, and flows into the indoor heat exchanger 5.
