Proportion computing technology obtains and shows an one driven multiple air conditioner of each interior machine electricity consumption ratio.
The technical solution adopted by the present invention is to propose a kind of interior machine electricity consumption proportion computing technology of an one driven multiple air conditioner, bag
Include：
Sample the capacity and expansion valve opening of each interior machine of electric current, air conditioner of certain moment air conditioner；
Electricity use value of each interior machine within a period of time is calculated according to each parameter of sampling；
Calculate total electricity use value of all interior machines of the air conditioner within this time；
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
During 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 comprising 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 time period t 1-t2 electricity use value in kth platform, wherein, I (t) is electric current, the C of t air conditionerk（t）For machine in t kth platform
Capacity, Vk（t）For the expansion valve opening of machine in t kth platform, t1<=t<=t2.
The invention also provides a kind of interior electromechanical amount distribution method 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
Calculate and obtain 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 stream voltage multiplies value is drawn.Or the true total power consumption of the air conditioner is measured by the external ammeter of air conditioner
Go out.When both values are inconsistent, the value that the external ammeter measurement of prioritizing selection air conditioner is drawn always consumes as the true 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.
Prior art is compared to, the present invention is according to the actual start of each indoor set effective refrigerating/heating time and interior
Situations such as function power, each interior electromechanical amount ratio of increase calculate, may then pass through external display or show electricity on machine indoors
The method of amount ratio, each user is set to get the electricity electricity charge that should each share.And the method applied in the present invention is implemented
Get up to be easier, implementation cost is low.
Brief description of the drawings
With reference to embodiment and accompanying drawing, the present invention is described in detail, wherein：
Fig. 1 is the flow chart of the present invention.
Embodiment
Fig. 1 be illustrated that 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 to the interior machine conveying energy of this.
In one embodiment, the common n indoor set of an one driven multiple air conditioner, i.e. n value are the nature more than or equal to 2
Number, in t, 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 set（Capacity and indoor set blower fan shelves
Position etc. is relevant, i.e.,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 relevant 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 aperture 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 equation 1 below, 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 initial time t1 ~ end time t2 of sampling period in n platforms machine total electricity use value QzIt can then lead to
Formula 2 is crossed to be calculated.
（Formula 2）
It so can be obtained by the electricity consumption ratio P for the interior machine that kth platform user useskFor：
（Formula 3）
The electricity ratio calculated by formula 3, it can be shown by the external special display of outer machine, be grasped by button
Carry out accumulative electricity ratio and show or removes to add up ratio and recalculate etc. to operate；Or directly pass through every interior machine
Display board is shown and associative operation.
If needing to calculate electricity, then it can continue following step.
Assuming that this time true total power consumption as caused by this one drags n air conditioners is S, then machine user should 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 uses the complete machine of itself measurement
The power consumption that the time integral that Current Voltage multiplies value obtains and true caused total power consumption are not consistent, it is impossible to directly use.
The power consumption that every interior machine user should bear is obtained, then according to electricity Unit Price, you can learn the electricity that each user should undertake
Take.
In view of in controller inconvenience do integral operation, and I (t) in formula 1,Value changes not
Can be too fast, can be with T at regular intervals（T can be set to such as 1min, 10min etc.）Once sampled, then when the t1 in formula 1 is
Between at the beginning of the cycle between, 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, formula 1 is converted into as follows：
(formula 5)
Formula 5 is updated in 2 ~ formula of formula 4, the formula that can be conveniently calculated.
Except 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
Protection obtains and shown an one driven multiple air conditioner of 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
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
