Based on one general inventive concept, the embodiment of the present utility model also provides a control method of the outdoor heat exchange device 8. Fig. 4 is a schematic flow chart provided in an embodiment of a control method of an outdoor heat exchange device 8 according to the present utility model, referring to fig. 4, the control method of an outdoor heat exchange device 8 according to the present utility model may be applied to the outdoor heat exchange device 8 described in any of the foregoing embodiments, and may include the following steps:
s41, judging whether the air conditioner is in a heating mode or a refrigerating mode;

and S43, if the air conditioner is in the heating mode, controlling the outdoor heat exchange device 8 to work in the evaporation mode.
Optionally, the outdoor heat exchange device 8 in the present embodiment includes a first control valve 5, a second control valve 4, and a third control valve 3, where the first control valve 5 is disposed on a pipeline between the second heat exchange portion 12 and the liquid collecting pipe 2, and is used to conduct the second heat exchange portion 12 and the liquid collecting pipe 2 in the condensing mode; in the evaporation mode, the second control valve 4 is used for conducting the first heat exchange portion 11 and the liquid collecting pipe 2 and conducting the second heat exchange portion 12 and the liquid collecting pipe 2, and the third control valve 3 is used for conducting the second heat exchange portion 12 and the gas distributing pipe 1.

when the air conditioner is in the refrigeration mode, the outdoor heat exchange device 8 is controlled to work in the condensation mode, and at the moment, the first control valve 5 is controlled to be opened, and the second control valve 4 and the third control valve 3 are controlled to be closed. The high-temperature and high-pressure refrigerant is discharged from the exhaust port of the compressor 6, enters the gas distribution pipe 1 through the four-way valve 7, flows through the first heat exchange part 11, the second heat exchange part 12 and the first control valve 5 in sequence, then enters the liquid collection pipe 2, and flows out of the liquid collection pipe 2, throttles by the throttling element 9, then enters the indoor heat exchange device 10, exchanges heat with the indoor heat exchange device 10, and then flows back to the air suction port of the compressor 6 through the four-way valve 7.
During refrigeration, the flow paths on the condensing side of the outdoor unit are less, the flow speed of the refrigerant is increased, the heat exchange coefficient is improved, the flow speed is increased, the pressure drop is increased, the influence of the pressure drop on the condensing side on the heat exchange temperature difference is small, the forward effect of the heat exchange coefficient improvement is more obvious, and therefore, the design of less flow paths is adopted on the condensing side.
When the air conditioner is in the heating mode, the outdoor heat exchange device 8 is controlled to work in the evaporating mode, at the moment, the second control valve 4 and the third control valve 3 are controlled to be opened, and the first control valve 5 is controlled to be closed.

During heating, the flow paths on the evaporation side of the outdoor unit are more, the flow speed is reduced, the pressure drop is reduced, meanwhile, the evaporation pressure is high, and the saturated evaporation temperature of the refrigerant is higher, so that frosting is not easy to occur, and the heat exchange efficiency is improved; the physical state of the refrigerant flow determines that the pressure drop of the evaporation side of the system is larger than the pressure drop of the condensation side, so that the energy efficiency of the system is greatly influenced, and the evaporation side is designed by adopting a multi-flow path.
The high-efficiency branching of refrigeration and heating, namely condensation and evaporation, is different for the heat exchanger, the connection relation and state change of the first heat exchange part 11 and the second heat exchange part 12 are realized through the flow path design, the relatively reduced branching of a condensation side system during the refrigeration of the air conditioner can be realized, the flow rate of the refrigerant at the inlet of the outdoor heat exchange device 8 is larger, the flow rate is enhanced, the heat exchange coefficient is improved, and the heat exchange enhancement effect is achieved; the evaporation side system branches are relatively increased during heating, so that the refrigerant can be branched, the fluid flow speed is reduced, the pressure drop is reduced, and the phenomenon that the heating performance of the air conditioner is affected by frosting due to lower heating low-pressure side pressure is avoided. The problem of the poor heat exchange of the current outdoor unit is solved, the development cost of the current air conditioner can be maintained, and the efficient heating is realized.
It is to be understood that the same or similar parts in the above embodiments may be referred to each other, and that in some embodiments, the same or similar parts in other embodiments may be referred to.
The foregoing is merely illustrative embodiments of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present utility model, and the utility model should be covered.
