Control module 430 calculates in the indoor units 200 (200a is to 200d) the electric energy rate of specific gravity of each, and calculating and indoor unit 200a in the 200d each proportional each indoor unit of electric energy rate value 200a to the power distribution amount of 200d.Promptly; The electric energy rate of specific gravity that power dispenser 400 calculates the respective chambers unit with respect to each indoor unit 200a to the electric energy rate of specific gravity of 200d and ratio, and calculate indoor unit 200a each power distribution amount in the 200d through this ratio being multiply by the power consumption total amount.
The method of calculating indoor unit 200a rate of specific gravity of each in the 200d is following.Control module 430 calculates the rate of specific gravity of each indoor unit 200a to 200d based at least one intrinsic parameter and a plurality of variable element of each indoor unit 200a in the operation information of 200d.Specifically, can each indoor unit 200a be categorized as various parameters to the operation information of 200d.Parameter is classified into and is used for indoor unit 200a to each at least one the intrinsic parameter with fixing eigenvalue and the variable element that changes to the specific run condition of 200d according to each indoor unit 200a of 200d.
Intrinsic parameter can refer to indoor unit 200a each capacity in the 200d, and the electric energy rate of specific gravity is with proportional as the indoor unit 200a of the intrinsic parameter capacity of each in the 200d.In other words, the capacity of indoor unit is big more, and the electric energy rate of specific gravity of respective chambers unit is high more, and this can be by 1 expression of following equality.In the present embodiment, BTU (British Thermal Unit, British thermal unit (BTU)) is used as bodge, and 1BTU approximates 0.252 kilocalorie.
Equality 1:
The capacity (BTU) of each indoor unit of electric energy rate of specific gravity ∝ of each indoor unit
In the variable element each comprise with each indoor unit 200a to the first relevant parameter of the operational mode of 200d, with the gas volume of indoor unit relevant second parameter and with at least one in the 3rd relevant parameter of the open degree of 210d of electric expansion valve 210a.In the operation information of 200d, the operational mode of indoor unit, the gas volume of indoor unit and electric expansion valve 210a are the power distribution amount needed major parameter of each indoor unit of calculating 200a to 200d to the open degree of 210d at each indoor unit 200a.First, second is according to the parameter of each indoor unit 200a to the service condition variation of 200d with the 3rd parameter.Therefore, when first, second changed with the 3rd parameter, each indoor unit 200a also changed to the power distribution amount of 200d.
Control module 430 calculates through the analog value with first, second and the 3rd parameter and multiply by the value that the predefined weight value obtains, and the electric energy rate of specific gravity with through with the value that obtains with the predefined weight value on duty of each parameter with proportional.
In the present invention, the on duty of each variable element calculated the electric energy rate of specific gravity with predefined weight value and summation.Here, the predefined weight value have respectively on the occasion of.Consider that the attribute of each variable element sets various weighted values, and can calculate various summing values thus.Hereinafter, explanation is used the anded of the predefined weight value of each parameter.
First parameter is the parameter relevant with the operational mode of indoor unit.The operational mode of indoor unit 200 comprises refrigeration mode, heating mode, defrosting mode, fan mode etc.During just in executable operations, compressed cold-producing medium flows into indoor unit in compressor 130 at indoor unit 200, and compressor 130 is carried out the work that the cold-producing medium that offers indoor unit 200 is compressed.But, if being the operation of fan mode or indoor unit 200, the operational mode of indoor unit 200 stops, then cold-producing medium does not flow into indoor unit 200, therefore, can judge that compressor 130 is not about the work of corresponding indoor unit 200.For example; If a plurality of indoor unit 200a stop or operating in fan mode to any 200a among the 200d; And other indoor unit 200b, 200c and 200d operate in refrigeration mode or heating mode; Although can judge that then compressor 130 is in fact moving, not work of compressor 130 about stopping or operating in the indoor unit 200a in the fan mode.In this case, the microcomputer (not shown) of indoor unit 200a transmits data " compressor stops " to the microcomputer (not shown) of outdoor unit 100, and these data are sent to power dispenser 400.Control module 430 is set the value of first parameter, if the data of receiving " compressor stops " then are set at 0 with this value.Simultaneously; Other indoor unit 200b, 200c and 200d beyond indoor unit 200a stops or operating under the situation of fan mode; Transmit data " compressor stops " from the microcomputer (not shown) of indoor unit 200b, 200c and 200d to the microcomputer (not shown) of outdoor unit 100, and these data are sent to power dispenser 400.Control module 430 is set the value of first parameter, if the data of receiving " compressor stops ", then with this value be set at predetermined on the occasion of.Preferably, predetermined on the occasion of being the value between 0.5 and 1.5.
Second parameter is the parameter relevant with the gas volume of indoor unit 200.The gas volume of indoor unit 200 can be set perhaps according to the specified scheme automatic setting through the direct input operation signal of user.Can the gas volume of indoor unit 200 be divided into basic, normal, high and very high.The gas volume of indoor unit 200 is big more, and the power distribution amount of corresponding indoor unit is big more.When the gas volume of indoor unit 200 was maximum, control module 430 was set at the value of second parameter very high.If indoor unit 200a is high for very to any one gas volume among the 200d, then the value of second parameter of respective chambers unit is a maximum.Preferably, this maximum is set to the value between 7 and 13.Then, high, in, weak can being set to have order less than peaked value.Needless to say, can set the value of second parameter according to user's setting according to each gas volume differently.
The 3rd parameter be with electric expansion valve 210a to the relevant parameter of the open degree of 210d.Flow into each indoor unit 200a to the flow velocity of the cold-producing medium of 200d according to being connected to the open amount variation of each indoor unit 200a to the electric expansion valve 210a of 200d to 210d.Method through increasing or reduce the pulse that puts on electric expansion valve is regulated its open degree.If the pulse that applies increases, then the open degree of electric expansion valve increases, and therefore when reduced-pressure refrigerant, passes through a large amount of cold-producing mediums.On the contrary, if the pulse that applies reduces, then its open degree also reduces, and therefore when reduced-pressure refrigerant, passes through lower amount of refrigerant.Therefore, the open degree of the value of the 3rd parameter and electric expansion valve is proportional.
According to being added on the variation of each indoor unit 200a to the indoor heat converter 220a of 200d to the overload of 220d, the increase of pulse is different with minimizing.For example; In refrigeration mode; If owing to design temperature reduces or reason such as outdoor temperature increase causes being added on indoor heat converter 220a and increases to the overload of 220d; The pulse that then puts on electric expansion valve increases to increase the open degree of this valve, increases the amount of the cold-producing medium that flows through this valve thus.By the open degree of the microcomputer (not shown) of indoor unit 200 control electric expansion valve, thereby and the microcomputer (not shown) of indoor unit 200 regulate the overload situations of the open degree reply indoor heat converter of electric expansion valve with the given time interval.
When the open degree of electric expansion valve when being maximum, control module 430 is set at the value of the 3rd parameter has maximum.Here, can maximum be set at the value that has between 30 to 40.When regulating the open degree of electric expansion valve through increase or minimizing pulse, if pulse value is set to 500 when the open degree of electric expansion valve is maximum, then the open amount of electric expansion valve is maximum.At this moment, the value of the 3rd parameter is above-mentioned maximum.Then, if the open degree of electric expansion valve reduces, then can the value of the 3rd parameter be set at linearity and reduce.Needless to say, can set the value of the 3rd parameter according to user's setting according to the open degree of electric expansion valve differently.
In the present invention, on duty with each variable element with predefined weight value and summation, thus calculate indoor unit 200a each electric energy rate of specific gravity in the 200d.Can import each predefined weight value by the user through input block 430, and therefore each predefined weight value can be with various rate of change.Suppose that first, second and the 3rd parameter have a, b and c (a＞0 respectively; B＞0; C＞0) weighted value, then value through using intrinsic parameter and each variable element and the predefined weight value method of calculating the electric energy rate of specific gravity of each indoor unit can be illustrated in the following equality 2:
Equality 2:
The capacity * of electric energy rate of specific gravity=each indoor unit of each indoor unit (the value * c of value * b+ the 3rd parameter of value * a+ second parameter of first parameter)
Preferably, will be set at respectively as the value of a, b and the c of predefined weight value the value that has between 50 to 70, have the value between 0.5 to 1.5 and have the value between 0.5 to 1.5.Calculate the rate of specific gravity of electric energy through using each variable element and predefined weight value.For example; If four indoor units are arranged; Suppose that indoor unit 200a is respectively 10BTU, 12BTU, 30BTU and 30BTU to the capacity of 200d, and indoor unit 200a is respectively refrigeration mode, refrigeration mode, defrosting mode and fan mode to the operational mode of 200d.In addition; Indoor unit 200a to the gas volume of 200d be respectively very high, in, neutralization is low, and indoor unit 200a is respectively the value of the value of the value of 500 pulses, 300 pulses, 200 pulses and the value of 200 pulses to the open amount of the electric expansion valve of 200d.In addition, suppose that the per minute power consumption total amount of in device for measurement of electrical energy 300, measuring is 500WH.
In this case, indoor unit 200a capacity of each in the 200d is that intrinsic parameter is respectively 10BTU, 12BTU, 30BTU and 30BTU.Therefore, the value of intrinsic parameter is respectively 10,12,30 and 30.
Suppose when indoor unit 200a when the operational mode of 200d is refrigeration mode and defrosting mode; The value of first parameter is 1; Its for predetermined on the occasion of; Indoor unit 200a is respectively refrigeration mode, refrigeration mode, defrosting mode and fan mode to the operational mode of 200d, thereby each indoor unit 200a is respectively 1,1,1 and 0 to the value of first parameter of 200d.At this moment, the weighted value of supposing a is 60, if first parameter is on duty with weighted value 60, the value that then obtains is respectively 60,60,60 and 0.
The value of second parameter can be set to indoor unit 200a proportional to the gas volume of 200d.If supposing maximum is 10, indoor unit 200a to the gas volume of 200d be respectively very high, in, neutralization is low, then can each indoor unit 200a be set at 10,6,6 and 4 respectively to the value of second parameter of 200d.At this moment, the weighted value of supposing b is 1, if on duty with weighted value 1 with second parameter, the value that then obtains is respectively 10,6,6 and 4.
The rate of specific gravity of in following equality 3, having represented each indoor unit that the value of value and each variable element through using intrinsic parameter is calculated:
Equality 3:
Electric energy rate of specific gravity=the 10* (60+10+36)=1060 of indoor unit 1 (200a)
Electric energy rate of specific gravity=the 12* (60+6+22)=1060 of indoor unit 2 (200b)
Electric energy rate of specific gravity=the 30* (60+6+14)=2400 of indoor unit 3 (200c)
Electric energy rate of specific gravity=the 30* (0+4+14)=540 of indoor unit 4 (200d)
Therefore, the power distribution amount of distributing to each indoor unit is shown in following equality 4:
Equality 4:
Power distribution amount=the 500*1060/5056=104.8WH of indoor unit 1 (200a)
Power distribution amount=the 500*1056/5056=104.4WH of indoor unit 2 (200b)
Power distribution amount=the 500*2400/5056=237.3WH of indoor unit 3 (200c)
Power distribution amount=the 500*540/5056=53.4WH of indoor unit 4 (200d)
