The electric energy meter 60 of the power circuit 50 that is connected in Utilities Electric Co. is set, to be used to measure total electric energy of many indoor sets 20 uses that comprise off-premises station 10 electricity usage amounts on the described off-premises station 10.Between described electric energy meter 60 and the order wire 40 power distributor 70 is set, this power distributor 70 communicates to connect with electric energy meter 60 and each indoor set 20 and the actual power that is used to distribute each indoor set 20 to use.
Described power distributor 70 deducts the power consumption sum of all indoor sets 20 and calculates out the power consumption of off-premises station 10 from the total electric energy of air-conditioning system of electric energy meter 60 metering, according to the running status (power consumption) of each indoor set 20 off-premises station 10 power consumptions that calculate out are distributed to each indoor set 20 then, grasp the actual electric power use amount of each indoor set 20 consumption thus.
Be provided for measuring the current sensor 22 of the consumption electric current of each indoor set 20 in described many indoor sets 20, current sensor 22 is connected and calculates the electric power of each indoor set 20 consumption with separately power line 30, send it to described power distributor 70 by order wire 40 then.
Fig. 2 controls block diagram for the electrical management of the air-conditioning system that the foundation embodiments of the invention provide.
Among Fig. 2, many indoor sets 20 comprise the current sensor 22 of the consumption electric current that is used to measure each indoor set 20 respectively and calculate the electric energy of each indoor set 20 consumption and send it indoor set microcomputer 24 of power distributor 70 to by order wire 40 according to the consumption galvanometer that described current sensor 22 is measured.
Described power distributor 70 comprises: calculation handling part 72, this calculation handling part 72 receives after the power consumption of the total electricity use amount of the air-conditioning system that electric energy meters 60 measure and each indoor set 20 that Duo Tai indoor set microcomputer 24 transmits, and deducts the power consumption sum of all indoor sets 20 and calculate out the power consumption of off-premises station 10 from the total electricity use amount; Power distributing part 74, the power consumption that is used for off-premises station 10 that described calculation handling part 72 is calculated out is assigned to each indoor set 20 corresponding to the running status (power consumption) of each indoor set 20; Control part 76 is used for described power distributing part 74 is assigned to the power consumption addition of off-premises station 10 power consumptions of each indoor set 20 and each indoor set 20 and accurately grasps the actual electric power use amount of each indoor set 20 and manage; Storage part 78 is used to store the actual electric power use amount of each indoor set 20 that described control part 76 grasps.
The following describes the air-conditioning system electrical management device with said structure and the course of work and the action effect of method thereof.
The electrical management workflow diagram of the air-conditioning system that Fig. 3 provides for the foundation embodiments of the invention.
At first, when the operating instruction of input air-conditioning system (S100), the off-premises station 10 of air-conditioning system and Duo Tai indoor set 20 bring into operation (S102).
At this moment, the current sensor 22 that is separately positioned on many indoor sets 20 power lines 30 is measured the electric current of each indoor set 20 consumption, and is entered into indoor set microcomputer 24 (S104) separately.
Thereupon, the consumption electric current that each indoor set microcomputer 24 is measured according to current sensor 22 calculates the electric energy (S106) of each indoor set 20 consumption, and each indoor set power consumption that will calculate sends power distributor 70 (S108) to by order wire 40.
Simultaneously, measure the total electricity use amount of many indoor sets 20 consumption that comprise off-premises station 10 electricity usage amounts when air-conditioning system is moved by the electric energy meter 60 of the power circuit 50 that is connected in Utilities Electric Co., and send it to power distributor 70 (S110).
Thereupon, in described power distributor 70, after the total electricity use amount of the air-conditioning system that calculation handling part 72 reception electric energy meters 60 measure and the power consumption of each indoor set 20 that Duo Tai indoor set microcomputer 24 transmits, the power consumption sum that deducts all indoor sets 20 from the total electricity use amount is calculated out the power consumption of off-premises station 10, and is entered into power distributing part 74 (S112).
Thereupon, the power consumption that described power distributing part 74 will be calculated the off-premises station 10 that handling part 72 calculates out is assigned to each indoor set 20 corresponding to the running status (power consumption) of each indoor set 20, and its result is input to control part 76 (S114).
After described control part 76 adds that on the power consumption of each indoor set 20 by the input of calculation handling part 72 off-premises station 10 power consumptions that power distributing part 74 is assigned to each indoor set 20 are grasped the actual electric power use amount of each indoor set 20 consumption, store the actual electric power use amount of each indoor set 20 of grasping into storage part 78, thus the electricity consumption (S116) of management air-conditioning system.
After this, when importing the operation halt instruction of air-conditioning system (S118), finish the everything of air-conditioning system.
In sum, according to air-conditioning system electrical management device provided by the present invention and method thereof, by the power consumption that current sensor is accurately measured each indoor set being set at many indoor set power ends, thereby can be corresponding to the outer electro-mechanical force consumption figure of each indoor set distributor chamber, can accurately grasp the actual electric power use amount of each indoor set consumption thus and accurately collect the electricity charge corresponding to each indoor set, thereby can avoid unnecessary friction, improve every user's satisfaction.
