The electronic expansion valve can effectively improve the intelligent level of the air conditioner and improve the control precision of the air conditioner.
Example two:
as shown in fig. 2, the difference from the first embodiment is that the first switching device 6 is provided on the second pipeline 10.

Example three:
As shown in fig. 3, the difference from the first embodiment is that the throttling mechanism 5 includes a throttling mechanism body 51 and a second switching device 52 connected in series, the third pipeline 20 is divided into a first sub-pipeline 201 and a second sub-pipeline 202 by the throttling mechanism body, and the second switching device 52 is disposed on the first sub-pipeline 201 and electrically connected to the controller to control the on-off of the first sub-pipeline 201 according to the received control signal of the controller, or the second switching device 52 is disposed on the second sub-pipeline 202 and electrically connected to the controller to control the on-off of the second sub-pipeline 202 according to the received control signal of the controller. The first sub-pipeline 201 and the second sub-pipeline 202 where the second switch device 52 is located can be switched on and off by controlling the second switch device 52.
The throttle body 51 may have a cut-off function, and at this time, the throttle body 51 may also be used to control the on/off of the third pipeline 20, for example, the throttle body 51 is an electronic expansion valve, so if the pipeline where the throttle 5 is located needs to be controlled to be conducted, the second switch device 52 and the throttle body 51 need to be controlled to be opened at the same time; the throttle body may also have no shut-off function, for example, the throttle body is a capillary tube or a thermostatic expansion valve.
The on-off control of the third pipeline 20 is realized through the combination of the throttle mechanism body 51 and the second switch device 52, so that the refrigerant can be stored in the outdoor heat exchanger 3 or the indoor heat exchanger 7 when the air conditioner shutdown compressor 1 stops running, and the cooling or heating speed is increased when the air conditioner is started next time.
Further, the second switching device 52 includes a second one-way electromagnetic cut-off valve or a second two-way electromagnetic cut-off valve.
the on-off of the third pipeline 20 can be controlled by the second one-way electromagnetic cut-off valve or the second two-way electromagnetic cut-off valve, for example, if the second switch device 52 is located on the first sub-pipeline 201, the on-off of the first sub-pipeline 201 is controlled by the second switch device 52, and if the second switch device 52 is located on the second sub-pipeline 202, the on-off of the second sub-pipeline 202 is controlled by the second switch device 52.
Further, the throttle mechanism body 51 includes a capillary tube, an electronic expansion valve, or a thermal expansion valve.
The capillary tube and the thermostatic expansion valve have simple structures and low cost, and the electronic expansion valve can effectively improve the intelligent level of the air conditioner and improve the control precision of the air conditioner.

The shutdown instruction can be from a remote controller of the air conditioner, that is, a user sends the shutdown instruction to the air conditioner through the remote controller. The air conditioner can also automatically shut down in an automatic control mode according to the change of the indoor or outdoor temperature to generate a shutdown instruction, for example, when the indoor ambient temperature is lower than the preset temperature in the refrigeration mode, the air conditioner automatically shuts down, for example, when the indoor ambient temperature is detected to be lower than the preset temperature, the shutdown instruction is generated.
The starting instruction can be from a remote controller of the air conditioner, namely, a user sends the starting instruction to the air conditioner through the remote controller.

Further, the control method comprises the following steps: step S802, in response to the power-on command, controls the throttle mechanism 5 and the first switch device 6 to be turned on, so as to turn on the third pipeline 20 and turn on the pipeline where the first switch device is located. When the throttle mechanism 5 includes the throttle mechanism body 51 and the second switching device 52, the throttle mechanism 5 is controlled to be opened, including controlling the second switching device 52 to be opened, so as to conduct the third pipeline 20 between the indoor heat exchanger 7 and the outdoor heat exchanger 3.
Step S802 may precede or follow step S806.
When step S802 precedes step S806, the control method further includes:
step S804, judging whether a shutdown instruction is received, wherein the shutdown instruction can be from an air conditioner remote controller;
If a shutdown command is received, step S806 is executed, and if no shutdown command is received, step S802 is returned to.
After shutdown, the next time the computer is started, step S802 is executed.
