Calculate the electricity consumption ratio of each interior machine.
Preferably, the sampling is once sampled every a time cycle, and the duration of each time cycle can be
1min or 10min etc..
Specifically, the value of expansion valve opening is determined by the type of expansion valve, when the expansion valve of the interior machine only switchs
When state, the value of the expansion valve opening of the interior machine is 0 or 1；When the aperture of the expansion valve of the interior machine is adjustable, institute
Between the value for stating the expansion valve opening of interior machine is 0 to 1 and it include 0 and 1.
Specifically, the electric current of the air conditioner can be the complete machine electric current of air conditioner, or using compressor for air conditioner
Electric current or outer electromechanical stream carry out approximate replacement.
The present invention calculates machine formula used by the electricity use value of time period t 1-t2 in kth platform, wherein I (t) is electric current, the C of t moment air conditionerk（t）For machine in t moment kth platform
Capacity, Vk（t）For the expansion valve opening of machine in t moment kth platform, t1<=t<=t2.
The invention also provides a kind of interior electromechanical amount distribution methods of an one driven multiple air conditioner, including：Using above-mentioned technical side
Interior machine electricity consumption proportion computing technology in case obtains the electricity consumption ratio of each interior machine, and obtains the true total power consumption of air conditioner, meter
It calculates and obtains the true electricity of each interior machine consumption.
Specifically, the true total power consumption of the air conditioner is electric according to the complete machine itself measured by the outer mainboard of air conditioner
The time integral that galvanic electricity pressure multiplies value obtains.Alternatively, the true total power consumption of the air conditioner is measured by the external ammeter of air conditioner
Go out.When the value of the two is inconsistent, preferentially select the value that the external ammeter measurement of air conditioner obtains as true total consumption of air conditioner
Electricity.
The invention also provides obtained and shown in each using the interior machine electricity consumption proportion computing technology in above-mentioned technical proposal
One one driven multiple air conditioner of machine electricity consumption ratio.
It is compared to the prior art, the present invention is according to the practical booting of each indoor unit effective refrigerating/heating time and interior
Situations such as function power, increases each interior electromechanical amount ratio and calculates, and may then pass through external display or on machine shows electricity indoors
The method of amount ratio enables each user to get the electricity electricity charge that should respectively share.And the method applied in the present invention is implemented
Get up to be easier, implementation cost is low.
Description of the drawings
With reference to embodiment and attached drawing, the present invention is described in detail, wherein：
Fig. 1 is the flow chart of the present invention.
Specific implementation mode
Fig. 1 show one embodiment of the invention propose an one driven multiple air conditioner interior machine electricity consumption proportion computing technology and
Power energy allocation method flow diagram.When an one driven multiple air conditioner more interior machines in the running, outer machine passes through the refrigerant that is connected with interior machine
Connecting tube and interior machine positive energy exchange, and expansion valve can control the circulation of connecting tube refrigerant.When outer machine is connected with certain interior machine
Expansion valve when being fully closed, actually outer machine has stopped conveying energy to the interior machine of this.
In one embodiment, the total n indoor unit of an one driven multiple air conditioner, the i.e. value of n are the nature more than or equal to 2
Number, in t moment, we can sample following data：The complete machine electric current I (t) of air conditioner is measured by outer machine controller
（Also compressor current or outer electromechanical stream approximate substitution can be used）, the capacity of kth platform indoor unit（Capacity and indoor unit wind turbine shelves
Position etc. is related, i.e.,It can be according to the real-time respective change of service condition）, the expansion valve opening that connects with machine in kth platform（t）.It is swollen
Swollen valve opening（t）It is related with the switchtype of expansion valve, there was only on off state for expansion valve,（t）Value be 0 or
1, and it is adjustable for the opening size of expansion valve,（t）The value between 0 ~ 1 can be taken according to switch size, and includes 0 and 1.
Then the parameter respectively sampled is updated to following equation 1, to calculate in kth platform machine in initial time t1 to terminating
Electricity use value Q in this period time t2k（Ratio）.
（Formula 1）
And within the period of the initial time of sampling t1 ~ end time t2 in n platforms machine total electricity use value QzThen may be used
To be calculated by formula 2.
（Formula 2）
It can be obtained by the electricity consumption ratio P for the interior machine that kth platform user uses in this waykFor：
（Formula 3）

Key operation carries out accumulative electricity ratio and show or remove the operations such as to add up ratio and recalculate；Or directly by every
The display board of machine carries out display and relevant operation.
If needing to calculate electricity, then it can continue following step.
Assuming that the true total power consumption that this time drags n air conditioners to generate by this one is S, then machine user answers in kth platform
The power consumption undertaken is as follows：
(formula 4)
S can be obtained accurate power consumption by air-conditioner external ammeter survey calculation, and outdoor machine of air-conditioner mainboard is measured using itself
Complete machine Current Voltage multiplies the power consumption that the time integral of value obtains and the total power consumption really generated is not consistent, cannot directly make
With.The power consumption that every interior machine user should bear is obtained, then according to electricity Unit Price, you can learn what each user should undertake
The electricity charge.
I (t) in view of integral operation is done in inconvenience in controller, and in formula 1,Value variation not
Can be too fast, it can be with T at regular intervals（T can be set as such as 1min, 10min etc.）It is once sampled, then when the t1 in formula 1 is
Between at the beginning of the period, t2 is the end time of time cycle.Assuming that in kth platform the m times value sampled of machine be I (m),, then in the timeT~In T time section, convert formula 1 to as follows：
(formula 5)
Formula 5 is updated in 2 ~ formula of formula 4, the formula for facilitating calculating can be obtained.
In addition to the interior machine electricity consumption proportion computing technology of an above-mentioned one driven multiple air conditioner, power energy allocation method, the present invention is gone back simultaneously
Protect the one driven multiple air conditioner for obtaining and showing electricity consumption ratio using the interior machine electricity consumption proportion computing technology.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
