S108: indoor unit processor receives initial opening value and initial opening value is sent to electric expansion valve；
S109: electric expansion valve is opened into initial opening value, and indoor unit processor opens fan；
S110: indoor unit starting.
It is now specific according to the initial opening value for the system information calculating electric expansion valve collected to the primary processor of S105
It is described as follows:
S1051: primary processor judges the operation mode that indoor unit need to be opened, if indoor unit need to open heating mode, turns
S1053 is gone to if indoor unit need to open refrigeration mode to S1052；
S1052: primary processor judges the operating status of compressor, if compressor is in operating status, goes to S1062,
If compressor is in off-mode, S1064 is gone to；
S1053: primary processor judges the operating status of compressor, if compressor is in operating status, goes to S1061,
If compressor is in off-mode, S1062 is gone to；
S1061: the capacity of the capacity for the indoor unit that primary processor starts according to the need collected and the indoor unit having been turned on
Ratio epsilon 1, multi-online air-conditioning system pressure at expulsion Pd1 and electric expansion valve default initial opening value S1 calculate electronics it is swollen
The initial opening value T1 of swollen valve；
S1062: the capacity of the capacity for the indoor unit that primary processor starts according to the need collected and the indoor unit having been turned on
Ratio epsilon 2, multi-online air-conditioning system pressure at expulsion Pd2 and electric expansion valve default initial opening value S2 calculate electronics it is swollen
The initial opening value T2 of swollen valve；
S1063: the ratio epsilon of the capacity of the capacity and outdoor unit for the indoor unit that primary processor starts according to the need collected '
3, the default initial opening value S3 of the environment temperature Tam3 of outdoor unit and electric expansion valve calculates the initial opening of electric expansion valve
Value T3；
S1064: the ratio epsilon of the capacity of the capacity and outdoor unit for the indoor unit that primary processor starts according to the need collected '
4, the default initial opening value S4 of the environment temperature Tam4 of outdoor unit and electric expansion valve calculates the initial opening of electric expansion valve
Value T4；
S107: primary processor sends each initial opening value to indoor unit processor.
In, the default initial opening value S of electric expansion valve is in different state and different modes in compressor
Relationship is as shown in table 1.
Table 1
Wherein, respectively the value range of default initial opening value S is respectively as follows:
The value range of S1 is 150~250；
The value range of S2 is 200~300；
The value range of S3 is 200~300；
The value range of S4 is 300~400.
Thus it will be seen that being in the default initial opening value of different state and different modes in compressor
The numerical values recited relationship of S is S1 < S3, S2 < S4.In this way, can be arranged different when compressor is in different operating statuses
Initial opening value the state of electric expansion valve can be grasped flexibly, according to different work operating conditions so that electric expansion valve
Open position can be directly reached, and is in the initial opening value under open state in compressor and is in shutdown less than compressor
Initial opening value under state reduces the unlatching step number of electric expansion valve, reduces the energy consumption of multi-online air-conditioning system.
In each step, the initial opening value T of electric expansion valve uses following algorithm:
1) when compressor is in operating status, the initial opening value T=S* α * γ of electric expansion valve.Initial opening value T
Minimum value TminValue range are as follows: in cooling mode, TminValue range be 100~150, in a heating mode, Tmin
Value range be 150~200；The maximum of T of initial opening value TmaxValue range are as follows: in cooling mode, TmaxTake
Being worth range is 250~300, in a heating mode, TmaxValue range be 300~350.
Wherein, correction value α is calculated according to the capacity for the indoor unit that need to start and the ratio epsilon of the capacity for the indoor unit having been turned on
It obtains, the relationship between the two is as shown in table 2.
Table 2
ε=all indoor units to be launched total capacity/all capacity for operating indoor unit, also, each correction value α
Value range is respectively as follows:
As ε < 0.5,1 value range of α: 1.0~1.2；
As 0.5 <=ε <=1.0, the value range of α 2 is 0.9~1.0；
As ε > 1.0, the value range of α 3 is 0.7~0.8.
Thus it will be seen that 1 > α of α, 2 > α 3, that is, correction value α with the indoor unit that need to start capacity with
The increase of the ratio epsilon of the capacity of the indoor unit of operating and reduce, that is to say, that initial opening value T is with the indoor unit that need to start
Capacity and the ratio epsilon of the capacity for the indoor unit having been turned on increase and reduce.
In this way, primary processor can according to need to start the capacity of indoor unit with operating the capacity ratio ε of indoor unit into
The amendment of row aperture, i.e., the initial opening value for the indoor unit that need to start is related with the capacity of all indoor units having been turned on, when need to open
When the total capacity of dynamic indoor unit is far below the capacity of all indoor units having been turned on, the numerical value of correction value α is in value range
Higher section, in this way, initial opening value T and correction value α are proportional, the numerical value of initial opening value T is in company with correction value α mono-
Sample is also in higher numberical range section, in this way, can further facilitate primary processor calculates the interior that need to start
The initial opening value of the electric expansion valve of machine is further reduced the aperture amendment frequency of the unlatching of electric expansion valve.
Meanwhile the numerical values recited of the initial opening value T of electric expansion valve is also related with correction value γ.Correction value γ is basis
The pressure at expulsion Pd of multi-line system is obtained, and the relationship between the two is as shown in table 3.
Table 3
Wherein, the value range of each correction value γ is respectively as follows:
As Pd < 24barG, the value range of γ 1 is 1.0~1.1；
As 24barG <=Pd <=29barG, the value range of γ 2 is 0.9~1.0；
As Pd > 29barG, the value range of γ 3 is 0.8~0.9；
As Pd < 20barG, the value range of γ 4 is 1.0~1.1；
As 20barG <=Pd <=25barG, the value range of γ 5 is 0.9~1.0；
As Pd > 25barG, the value range of γ 6 is 0.8~0.9.
It can thus be seen that when machine opens refrigeration mode indoors, 1 > γ of γ, 2 > γ 3, that is, correction value γ is with multi-joint
The increase of the pressure at expulsion Pd of machine system and reduce；When machine opens heating mode indoors, 4 > γ of γ, 5 > γ 6, that is, correction value
γ reduces with the increase of the pressure at expulsion Pd of multi-line system.
In this way, primary processor can carry out aperture amendment, i.e., the room that need to start according to the pressure at expulsion Pd of multi-line system
The initial opening value of interior machine and the pressure at expulsion Pd of multi-line system are related, when the pressure at expulsion Pd of multi-line system is in lower
Numerical value when, the numerical value of correction value γ is in the higher section of value range, in this way, initial opening value T and correction value γ are at just
Than relationship, the numerical value of initial opening value T is equally also in higher numberical range section in company with correction value γ, in this way, can be with
Further facilitate the initial opening value that primary processor calculates the electric expansion valve for the indoor unit that need to start, is further reduced electricity
The aperture of the unlatching of sub- expansion valve corrects the frequency.
2) when compressor is in off-mode, the initial opening value T=S* β * ζ of electric expansion valve.Initial opening value T's
Minimum value TminValue range are as follows: in cooling mode, TminValue range be 100~200, in a heating mode, Tmin's
Value range is 250~300；The maximum of T of initial opening value TmaxValue range are as follows: in cooling mode, TmaxValue
Range is 300~350, in a heating mode, TmaxValue range be 400~450.
Wherein, correction value β is according to the ratio epsilon of the capacity for the indoor unit that need to start and the capacity of outdoor unit ' it is calculated,
Relationship between the two is as shown in table 4.
Table 4
ε '=all indoor units to be launched total capacity/outdoor unit capacity, also, the value range of each correction value β point
Not are as follows:
As ε ' < 0.5,1 value range of β: 1.0~1.2；
As 0.5 <=ε ' <=1.0, the value range of β 2 is 0.9~1.0；
As ε ' > 1.0, the value range of β 3 is 0.7~0.8.
It can thus be seen that 1 > β of β, 2 > β 3, that is, correction value β with the indoor unit that need to start capacity and outdoor unit
The ratio epsilon of capacity ' increase and reduce, that is to say, that bright, initial opening value T is with the capacity of the indoor unit that need to start and outdoor
The ratio epsilon of the capacity of machine ' increase and reduce.
It is repaired in this way, primary processor can carry out aperture according to the capacity ratio ε ' for the capacity and outdoor unit that need to start indoor unit
Just, i.e., the initial opening value for the indoor unit that need to starting is related with the capacity of outdoor unit, when the total capacity for the indoor unit that need to start is remote
Lower than outdoor unit capacity when, the numerical value of correction value β is in the higher section of value range, in this way, initial opening value T and amendment
Value β is proportional, and the numerical value of initial opening value T is equally also in higher numberical range section in company with correction value β, this
Sample can further facilitate the initial opening value that primary processor calculates the electric expansion valve for the indoor unit that need to start, into one
The aperture that step reduces the unlatching of electric expansion valve corrects the frequency.
Meanwhile the initial opening value T numerical values recited of electric expansion valve is also related with correction value ζ.Correction value ζ is according to outdoor
The environment temperature Tam of machine is obtained, and the relationship between the two is as shown in table 5.
Table 5
Wherein, the value model of each correction value ζ are as follows:
Under refrigeration mode,
When 20 DEG C of Tam <, the value range of ζ 1 is 1.0~1.1；
When 20 DEG C of <=40 DEG C <=Tam, the value range of ζ 2 is 0.9~1.0；
When 40 DEG C of Tam >, the value range of ζ 3 is 1.0~1.1；
Under heating mode,
When 10 DEG C of Tam <, the value range of ζ 4 is 1.0~1.1；
When 10 DEG C of <=15 DEG C <=Tam, the value range of ζ 5 is 0.9~1.0；
When 15 DEG C of Tam >, the value range of ζ 6 is 0.8~0.9.
It can thus be seen that when machine opens refrigeration mode indoors, 1 > ζ of ζ, 3 > ζ 2, that is, ring of the correction value ζ in outdoor unit
Numerical value of the border temperature at 40 DEG C of Tam > is less than numerical value when being in 20 DEG C of Tam <, and is greater than 20 DEG C of <=40 DEG C <=Tam
When numerical value, that is, initial opening value T outdoor unit environment temperature be greater than 40 DEG C when numerical value be greater than initial opening value T in outdoor
Numerical value of the machine environment temperature between 20 DEG C and 40 DEG C, and it is less than initial opening value T when outdoor unit environment temperature is less than 20 DEG C
Numerical value；When machine opens heating mode indoors, 4 > ζ of ζ 5 > ζ 6, that is, correction value ζ with outdoor unit environment temperature Tam
Increase and reduce, initial opening value T also with the environment temperature Tam of outdoor unit increase and reduce.
In this way, can further facilitate initially opening for the electric expansion valve for the indoor unit that primary processor calculating need to start
Angle value is further reduced the aperture amendment frequency of the unlatching of electric expansion valve.It can thus be seen that when compressor is in operation shape
When state, when the capacity for the indoor unit that need to start is smaller, the initial opening of the calculated electric expansion valve of primary processor
It is worth larger, can to protect to avoid low pressure/row's temperature of outdoor unit in this way, and then starting indoor unit is avoided to generate noise.When need to open
When the capacity of dynamic indoor unit is larger, the initial opening value of the calculated electric expansion valve of primary processor is smaller, in this way can be more
The fast system balancing for reaching multi-online air-conditioning system.Also, under worst cold case, when the indoor unit capacity that need to start is larger
When, the initial opening value of the calculated electric expansion valve of primary processor is smaller, easily establishes height pressure difference in this way, guarantees refrigerant
Circulate.When compressor is in off-mode, when the indoor unit capacity that need to start is smaller, primary processor is calculated
The initial opening value of electric expansion valve is larger, but when the environment temperature of outdoor unit is greater than 40 DEG C, initial opening value is greater than and works as room
Numerical value of the outer machine environment temperature between 20 DEG C to 40 DEG C, such primary processor control electricity according to different outdoor unit environment temperatures
The initial opening value of sub- expansion valve to adapt to different operating conditions, and can reduce the noise that starting indoor unit generates, together in this way
When multi-online air-conditioning system fluctuation it is smaller, new system balancing can be set up faster.When the appearance for the indoor unit that need to start
When measuring larger, the initial opening value of the calculated electric expansion valve of primary processor is smaller, can reduce the noise of indoor unit in this way,
The fluctuation of simultaneity factor is smaller, it is easier to set up new system balancing faster.
