Further, before the target opening value (i.e. above-mentioned steps 101) for obtaining the first electric expansion valve, above-mentioned control
Method can also include:The dial-up value of indoor unit when air-conditioner outdoor unit will also be run according to the booting of air-conditioning, to determine air-conditioning
Machine type.Wherein, for air-conditioning when being switched on operation, dial-up value can be sent to air-conditioner outdoor unit, air conditioning chamber by air conditioner indoor unit
Outer machine determines the machine type of air-conditioning according to the dial-up value received.
If the machine type of air-conditioning is non-not cool-down dehumidification air-conditioning type, air-conditioner outdoor unit can directly cache buffer area
The opening value of 1 electric expansion valve be sent to air conditioner indoor unit.
If the machine type of air-conditioning is that cool-down dehumidification air-conditioning type, air-conditioner outdoor unit do not need the M to air conditioner indoor unit
The aperture control information of a electric expansion valve is updated.
In step 201, the target opening value of the first electric expansion valve is obtained.
Air conditioner indoor unit includes M electric expansion valve, and first electric expansion valve is in the M electric expansion valve
Need any one electric expansion valve of update aperture.Wherein, the target opening value of the first electric expansion valve refers to first electricity
The sub- expansion valve opening value to be updated to.Exemplary, opening value when two electric expansion valves of A, B are switched on is all 8%, because of sky
Adjusting system operation needs, and needs A electronic expansion valve opening values being adjusted to 10%, then, A electric expansion valves are the first electronics
Expansion valve, correspondingly, 10% be the first electric expansion valve target opening value.
The acquisition methods of the target opening value of the first expansion valve in this step can there are many.For example, can be indoor
Air conditioner feeds back to outdoor air-conditioner;Can also be that outdoor air-conditioner gets the first electricity according to the operating condition of air-conditioning system

Get the target aperture of the first electric expansion valve according to the operating condition of air-conditioning system with air-conditioner outdoor unit below
For value, the method that air-conditioner outdoor unit obtains the target opening value of the first electric expansion valve is specifically introduced:
Judge whether the aperture of an electric expansion valve in the M electric expansion valve needs to update, specifically, air conditioning chamber
Outer machine is scanned the M electronic expansion valve opening value that buffer area caches respectively, determines the M electric expansion valve that buffer area changes
In corresponding two opening values of an electric expansion valve it is whether consistent.If it is determined that corresponding two opening values of the electric expansion valve
It is inconsistent, determine that the opening value of the electric expansion valve needs to update, then the electric expansion valve is the first electric expansion valve.
Wherein, corresponding two opening values of each electric expansion valve are respectively the first opening value and the second opening value, each
Opening value corresponds to the opening value that different time points are cached to the electronic expansion of buffer area, for example, the first opening value corresponding time
Point 21 points 22 seconds 35 minutes, the second opening value corresponding time point be 21 points 42 seconds 36 minutes.
Further, the first opening value corresponding time point and the difference of current time be less than the second opening value it is corresponding when
Between point and the difference of current point in time.For example, 35 minutes and 42 seconds 21 points of the first opening value corresponding time point, the second opening value corresponds to
Time point be 21 points 22 seconds 36 minutes, current time be 21 points 52 seconds 36 minutes, then can determine that the first opening value corresponds to time point
Difference with current time is 10 seconds, and the difference of the second opening value corresponding time point and current time is 30 seconds.
Further, if air-conditioner outdoor unit determines in the M electric expansion valve that buffer area caches, first electric expansion valve
Two opening values it is inconsistent, it is determined that the aperture of first electric expansion valve needs to update, and first electric expansion valve is true
It is set to the first electric expansion valve, while the first opening value of first electric expansion valve is determined as target opening value.For example, the
First opening value of one electric expansion valve is 20%, and the second opening value of the first electric expansion valve is 30%, due to first
Corresponding first opening value of electric expansion valve and the second opening value are inconsistent, can the first opening value be determined as the first electronics
The target opening value of expansion valve.
If air-conditioner outdoor unit determines the aperture of first electric expansion valve in M electric expansion valve of buffer area caching not
It needs to update, then can sequentially judge whether the aperture of second electric expansion valve in M electric expansion valve needs to update.Tool
Body, when two opening values of second electric expansion valve are inconsistent, determine the opening value needs of second electric expansion valve
Second electric expansion valve is determined as the first electric expansion valve by update, while by the first aperture of second electric expansion valve
Value is determined as target opening value.
If air-conditioner outdoor unit determines in M electric expansion valve of buffer area caching, the two of first, second electric expansion valve
A opening value is inconsistent, it is determined that the opening value of first, second electric expansion valve has update, then by first, second electronics
Expansion valve is all determined as the first electric expansion valve, and the first aperture Distribution value of first, second electric expansion valve is true
It is set to target opening value, it, then can be swollen according to electronics since the first determining electric expansion valve has corresponded to two electric expansion valves
The serial number of swollen valve is ranked up, for example, first electric expansion valve can be arranged as to primary first electric expansion valve, it will
Second electric expansion valve is arranged as deputy first electric expansion valve;Second electric expansion valve can also be arranged as to
First electronic expansion is arranged as deputy first electric expansion valve by one the first electric expansion valve;The present invention is real
It applies in example, to determining that the quantity of how many first electric expansion valves does not do specific restriction from M electric expansion valve, and meanwhile it is right
The ordering of multiple first electric expansion valves does not do specific restriction yet.
In above-described embodiment, the first electric expansion valve got is to need newer aperture in M electric expansion valve
One electric expansion valve.
In step 202, it generates aperture and controls information.Aperture control information accounts for continuous N number of byte, including accounts for continuous s
The mark of first electric expansion valve of a bit and account for continuous t bit the first electric expansion valve target opening value.
In practical applications, communication information is generated according to communications protocol between air-conditioner outdoor unit and air conditioner indoor unit
, as shown in figure 3, it may include U byte (8U bit).In embodiments of the present invention, aperture control information only takes up
N number of byte in communication information, certain communication information can also include other information, and other information and the embodiment of the present invention
It is unrelated, therefore herein without limitation.
Aperture control information is used to control the aperture of any of M electric expansion valve in air conditioner indoor unit, accounts for wherein
N number of byte (8N bit), such as:As shown in figure 3, N number of byte accounts for a part of byte in U byte, can be i-th
Byte to i-th+N number of byte.Aperture control information includes the mark of the first electric expansion valve and the mesh of the first electric expansion valve
Mark opening value.
Wherein, the mark of the first electric expansion valve is for indicating which of M electric expansion valve first electric expansion valve be
It is a, according to binary counting principle, can learn M electric expansion valve can at least be needed with binary representation respectively it is several
A bit number is indicated with s.It is exemplary, if M is 2, s 1, you can to use 1 bit as this 2 electric expansion valves
Flag indicates this 2 electric expansion valves respectively with " 0 ", " 1 ".It is again exemplary, if M is 3, s 2, you can be compared with 2
The special flag as this 3 electric expansion valves.
The target opening value of first electric expansion valve is obtained in step 201, since the first electric expansion valve is M
Any of electric expansion valve, therefore, the bit number accounted for needed for target opening value need that any one electric expansion valve can be written
Maximum opening value.Exemplary, if there is 2 electric expansion valves in indoor unit, the maximum opening value of one of them is
2000Pluse, another maximum opening value is 1800Pluse, then maximum opening value is in this 2 electric expansion valves
2000Pluse at least needs 11 bits, i.e. t=11 at this time;It is again exemplary, if there is 3 electric expansion valves in indoor unit,
This 3 maximum opening value is 2000Pluse, 2000Pluse, 1800Pluse respectively, then in this 3 electric expansion valves most
Big opening value is 2000Pluse, at least needs 11 bits, i.e. t=11 at this time.
In addition, those skilled in the art can be derived that according to the meaning of above-mentioned N, s, t, s+t is less than or equal to 8N.
In embodiments of the present invention, M electric expansion valve in air conditioner indoor unit has mark, and the mark is correspondingly
It is buffered in the buffer area for being stored in air-conditioner outdoor unit.A kind of situation is, every in the M electric expansion valve cached in buffer area
Each opening value of a electric expansion valve is corresponding with mark;A kind of situation is, in the M electric expansion valve cached in buffer area
The corresponding mark of each electric expansion valve, and the mark and two opening values of electric expansion valve are corresponding respectively.This
In inventive embodiments, each mark of electric expansion valve and the correspondence of electric expansion valve in M electric expansion valve are not done
It is specific to limit.
Further, the mark of each electric expansion valve in M electric expansion valve is different.
After air-conditioner outdoor unit obtains the target opening value of the first electric expansion valve, air-conditioner outdoor unit will be got simultaneously
The mark of first electric expansion valve.Correspondingly, it converts the target opening value of the first electric expansion valve to and accounts for continuous t bit
It when target opening value, is also converted to the mark of the first electric expansion valve to account for the mark of s bit, then will account for continuous s ratio
The mark of the first special electric expansion valve and account for continuous t bit the first electric expansion valve the generation aperture control of target opening value
Information processed.
In above-described embodiment, the mark of first electric expansion valve first can be switched to account for s bit by air-conditioner outdoor unit
Mark, then convert the target opening value of the first electric expansion valve to the target opening value for accounting for continuous t bit;It will can first be somebody's turn to do
The target opening value of first electric expansion valve is converted into the target opening value for accounting for continuous t bit, then by the first electric expansion valve
Mark switch to the mark for accounting for s bit;Can also the mark of the first electric expansion valve be switched into the mark for accounting for s bit simultaneously
Know, converts the target opening value of the first electric expansion valve to the target opening value for accounting for continuous t bit.The embodiment of the present invention
In, the sequencing that the mark of the first electric expansion valve or target opening value are switched to bit value to air-conditioner outdoor unit does not do and has
The restriction of body.
Below for when M is equal to 2,2 electric expansion valves can be controlled in air conditioner indoor unit by introducing air-conditioner outdoor unit
Opening value.
Specifically, table one is the aperture control information format for occupying 2 bytes, since M is equal to 2, you can with 2 bits
