The direction changing unit 2 has first to fourth ports, the first port being connected to the exhaust port 11, and the third port being connected to the suction port 12.
the first end of the outdoor heat exchanger 3 is connected with the second port, and the first end of the indoor heat exchanger 9 is connected with the fourth port.
The throttling mechanism 5 is connected in series between the second end of the outdoor heat exchanger 3 and the second end of the indoor heat exchanger 9.
the bypass pipeline 7 is connected to two ends of the throttling mechanism 5 in parallel, a switch device 6 is arranged on the bypass pipeline 7, and the switch device 6 is used for controlling on-off of the bypass pipeline 7.
In response to the cooling mode power-on command, the switching device 6 is turned on to conduct the bypass line 7.
The compressor 1, the reversing assembly 2, the outdoor heat exchanger 3, the throttling mechanism 5 and the indoor heat exchanger 9 are sequentially connected to form a refrigerant circulation loop. In the cooling mode, the flow path of the refrigerant is as follows: the refrigerant discharged from the discharge port 11 of the compressor 1 flows through the first port and the second port to the first end of the outdoor heat exchanger 3, and flows out through the second end of the outdoor heat exchanger 3. When the switching device 6 is turned on and the bypass pipeline 7 is conducted, the refrigerant flowing out through the second end of the outdoor heat exchanger 3 is divided into two paths, one path flows to the second end of the indoor heat exchanger 9 through the bypass pipeline 7, the other path flows to the second end of the indoor heat exchanger 9 through the throttling mechanism 5, then flows out to the fourth port from the first end of the indoor heat exchanger 9, and flows back to the suction port 12 of the compressor 1 through the third port. When the switching device 6 is turned off and the bypass pipeline 7 is disconnected, the refrigerant flowing out of the second end of the outdoor heat exchanger 3 flows to the second end of the indoor heat exchanger 9 through the throttling mechanism 5, then flows out of the first end of the indoor heat exchanger 9 to the fourth port, and flows back to the suction port 12 of the compressor 1 through the third port.
The throttle mechanism 5 can be a capillary tube, a one-way throttle valve, a two-way throttle valve, a thermostatic expansion valve or an electronic expansion valve.
in the air conditioner provided by the above embodiment of the present invention, when the air conditioner receives the start instruction of the refrigeration mode, the air conditioner is started, the control switch device 6 is turned on, the bypass pipeline 7 is conducted, and after the refrigerant discharged from the exhaust port 11 of the compressor 1 passes through the outdoor heat exchanger 3, at least a part of the refrigerant flowing out from the second end of the outdoor heat exchanger 3 can flow into the indoor heat exchanger 9 through the bypass pipeline 7, so that the refrigerant can flow into the indoor heat exchanger 9 in time at the start stage, thereby increasing the amount of the refrigerant entering the indoor heat exchanger 9 at the start stage, and accelerating the start refrigeration speed.
further, the switching device 6 may be a solenoid valve, such as a one-way solenoid valve. The one-way electromagnetic valve (one-way electromagnetic stop valve) can realize the control of the on-off of the bypass pipeline 7, wherein the control of the one-way electromagnetic valve is simpler and the cost is lower.
Example two:
The difference from the first embodiment is that the switching device 6 includes a two-way solenoid valve (two-way solenoid shut-off valve).
It will be appreciated that the switching device 6 may also be a shut-off valve having the same function, other than a one-way solenoid valve or a two-way solenoid valve.

In the control method provided by the embodiment of the second aspect of the present invention, in response to a start-up command of a refrigeration mode, the switch device 6 is controlled to be opened, so that the bypass pipeline 7 is conducted, and thus after the refrigerant discharged from the exhaust port 11 of the compressor 1 passes through the outdoor heat exchanger 3, at least a part of the refrigerant flowing out from the second end of the outdoor heat exchanger 3 can flow into the indoor heat exchanger 9 through the bypass pipeline 7, compared with the case that the refrigerant can only flow into the indoor heat exchanger 9 through the throttling mechanism 5 in the start-up stage in the related art, the setting of the bypass pipeline 7 in the present application can increase the amount of the refrigerant entering the indoor heat exchanger 9 in the start-up stage, so that the refrigerant can flow into the.
Example four:
As shown in fig. 3, the control method includes:
step S302, in response to the cooling mode power-on command, controls the switch device 6 to be turned on, so as to turn on the bypass pipeline 7.
in response to the starting instruction of the refrigeration mode, the control switch device 6 is opened, and the refrigerant in the outdoor heat exchanger 3 can flow into the indoor heat exchanger 9 through the bypass pipeline 7, so that the amount of the refrigerant flowing into the indoor heat exchanger 9 is increased in a short time, and quick refrigeration is realized.
The refrigeration mode power-on instruction can be from a remote controller of the air conditioner, namely, a user sends the refrigeration mode power-on instruction to the air conditioner through the remote controller. The air conditioner can also adopt an automatic control mode, for example, when the indoor environment temperature is higher than the preset temperature, the air conditioner is automatically started, for example, the indoor environment temperature is detected to be higher than the preset temperature, and a starting instruction is generated.
as shown in fig. 4, further, step S302 includes:
Step S3022, in response to the cooling mode power-on instruction, determining whether the switching device 6 is on;
If the switching device 6 is not turned on, executing step S3024, controlling the switching device 6 to be turned on, and executing step S304 after the switching device is turned on, so as to control the compressor 1 to be started, further, the compressor 1 can be started at a high frequency or started at a fast frequency;
if the switching device 6 is determined to be turned on, step S304 is executed to control the compressor 1 to start, and further, the compressor 1 can be started at a high frequency or quickly started at an increased frequency.
It should be noted that the step of controlling the start of the compressor 1 may be before, during or after the control switch device 6 is turned on.
when the control switch device 6 is turned on or during the control switch device 6 or after the control switch device 6 is turned on in response to the cooling mode power-on command, the method further comprises the following steps:
And step S304, controlling the compressor 1 to start, further controlling the compressor 1 to start at a preset frequency in a high frequency mode or controlling the compressor 1 to start at a preset frequency increasing rate in a rapid frequency increasing mode.
when the control switch device 6 is turned on, in the process of turning on the control switch device 6 or after the control switch device 6 is turned on, the compressor 1 is controlled to start at high frequency or start at fast rising frequency. On the one hand, the compressor 1 rapidly pumps the refrigerant in the indoor heat exchanger 9 to the suction port 12 of the compressor 1 in a short time, and on the other hand, the discharge port 11 of the compressor 1 outputs the refrigerant to the outdoor heat exchanger 3.
With the switching device 6 turned on, the refrigerant pumped back to the compressor 1 from the indoor heat exchanger 9 flows into the outdoor heat exchanger 3 after being discharged through the exhaust port 11 of the compressor 1, and is divided into two paths after passing through the second end of the outdoor heat exchanger 3, wherein one path flows into the indoor heat exchanger 9 through the bypass pipeline 7, and the other path flows into the indoor heat exchanger 9 through the throttling mechanism 5.
The mode of high-frequency starting or quick frequency-raising starting of the compressor 1 can quickly draw the refrigerant in the indoor heat exchanger 9 back to the compressor 1, then the refrigerant flows out of the outdoor heat exchanger 3 through the exhaust port 11 of the compressor 1 and is supplemented to the indoor heat exchanger 9 through the throttling mechanism 5 and the bypass pipeline 7, the amount of the refrigerant entering the indoor heat exchanger 9 through the throttling mechanism 5 is further increased, and therefore the refrigerating speed is further improved.
Further, in step S304, the preset frequency is greater than or equal to 50Hz, so as to realize the high-frequency start of the compressor 1, i.e. the air conditioner compressor 1 is directly started and operated at a higher frequency. Optionally, the preset frequency is greater than or equal to 65 Hz.
Further, in step S304, the preset frequency-increasing rate is greater than or equal to 5Hz/S, so as to achieve fast frequency-increasing of the compressor 1, that is, after the air conditioner compressor 1 is started, the frequency is rapidly increased to a higher value in a short time, thereby achieving the purpose of fast refrigeration.
The high-frequency starting or the quick frequency-raising starting of the compressor 1 can quickly suck the refrigerant in the indoor heat exchanger 9 to the compressor 1 in a short time, so that the amount of the refrigerant discharged to the indoor heat exchanger 9 through the outdoor heat exchanger 3 and discharged through the exhaust port 11 of the compressor 1 is increased, the amount of the refrigerant entering the indoor heat exchanger 9 through the throttling mechanism 5 is increased, the quick reduction of the air outlet temperature of the starting machine is realized, and the quick refrigeration is realized.
Further, the control method further comprises:
in step S306, after the compressor 1 runs for a preset time, the switching device is controlled to be turned off, so as to disconnect the bypass pipeline 7.
After the compressor 1 is started and operates for a preset time, the starting stage is completed or basically completed, in order to ensure normal refrigeration of the air conditioner, the control switch device is closed at the moment, the bypass pipeline 7 is disconnected, the refrigerant flowing out of the second end of the outdoor heat exchanger 3 flows into the second end of the indoor heat exchanger 9 through the throttling mechanism 5, the throttling effect of the refrigerant is ensured, normal operation of the air conditioner is realized, and the refrigeration effect is ensured.
Further, in step S306, the preset duration is in the range of 20S to 180S, which prevents the bypass pipeline 7 from being disconnected when the preset duration is shorter than 20S, resulting in insufficient refrigerant accumulation in the indoor heat exchanger 9 and insufficient quick refrigeration effect, and prevents the bypass pipeline 7 from being disconnected when the preset duration is longer than 180S, resulting in excessive refrigerant flowing out of the second end of the outdoor heat exchanger 3 and then flowing into the indoor heat exchanger 9 through the bypass pipeline 7 without passing through the throttling function of the throttling mechanism 5, thereby affecting the refrigeration effect of the air conditioner.
The preset time period may be, but is not limited to, 20s, 60s, 120s, or 180 s.
As shown in fig. 5, in a specific embodiment, the control method of the air conditioner includes steps S402 to S410.
When the air conditioner is started, the switch device 6 is turned on, and the compressor 1 is started at a high frequency or quickly started in an up-conversion mode, so that the flow of a refrigerant passing through the throttling mechanism 5 in the starting stage is increased, the refrigerant is timely supplemented to the indoor heat exchanger 9, the refrigerating speed is accelerated, the switch device 6 needs to be turned off after the compressor 1 runs for a preset time, and the throttling effect of the refrigerant is guaranteed.
To sum up, the switch device 6 is connected in parallel at the throttle mechanism 5, the switch device 6 is turned on when the refrigerator is started, the flow of the refrigerant entering the indoor heat exchanger 9 when the refrigerator is started is increased, the speed of cooling air discharged when the refrigerator is started can be increased, and the effect of quick refrigeration is achieved.
