Below, with reference to Fig. 6 the control procedure of air-conditioning electric weight is described in detail:
At first, in the present invention in order to control the electric weight of air-conditioning, need to set in advance the highest charge value (or upper limit electric weight).The highest electric weight is set by the user, and after promptly the user set the highest charge value by signal input part 50e, master controller 50b preserved the highest charge value of having set, and confirms at any time.
After setting the highest charge value, the user imports the order of control air-conditioning electricity usage amount, and master controller 50b begins to control the electric weight of air-conditioning.
Master controller 50b sends the signal that makes its connection network for network interface 40 by protocol adaptor 50a.The protocol adaptor 40a of network interface 40 receives above-mentioned signal, is input among the microcomputer 40d.Microcomputer 40d assigns the network bind command for controller 40a.After controller 40a connects network, in time receive the power value that dynamometer instrument 10 detects by network 20.Simultaneously, dynamometer instrument 10 is kept and being connected of network by network controller 10c.The power value that dynamometer instrument 10 detects is stored in the server 60 by network 20.After server 60 receives the power value transmission signal of controller 40a, the power value that the transmission of in time continuing for controller 40a detects.Controller 40a sends the power value that receives to microcomputer 40b, and microcomputer 40d sends control part 50 to again by protocol adaptor 40d.
By said process, the power value that is received by the protocol adaptor 50a of control part 50 is input among the master controller 50b.
Whether the power value that described master controller 50b is relatively imported has reached below 80% of the highest power value (the 100th stage).
If satisfy condition in the 100th stage, promptly the power value that is received by network is at 80% when following of the highest power value, and master controller 50b keeps the operating frequency (the 103rd stage) of compressor 50c, judges in this case that promptly electric weight also has more than needed.
If when not satisfying the condition in the 100th stage, whether the power value that master controller 50b relatively imports is below 90% of the highest power value (the 106th stage).
When if situation satisfies the condition in the 106th stage, promptly the power value that receives by network is at 90% when following of the highest power value, and master controller 50b reduces about 5% (the 109th stages) that show operating frequency.
If when also not satisfying the condition in the 105th stage, whether the power value that master controller 50b relatively imports is below 95% of the highest power value (the 112nd stage).
When if situation satisfies the condition in the 112nd stage, promptly the power value that receives by network is at 95% when following of the highest power value, and master controller 50b reduces about 10% (the 115th stages) that show operating frequency.
If when also not satisfying the condition in the 112nd stage, whether the power value that master controller 50b relatively imports is below 100% of the highest power value (the 118th stage).
When if situation satisfies the condition in the 118th stage, promptly the power value that receives by network is at 100% when following of the highest power value, and master controller 50b reduces about 15% (the 115th stages) that show operating frequency.
If when also not satisfying the condition in the 118th stage, master controller 50b stops compressor 50c running (the 124th stage).
In described the 109th stage, in the 115th stage, the 121st stage was the more stage of power consumption, therefore made power consumption by reducing to load to reduce.But the 124th stage was the too much stage of power consumption, and this moment, the load of air-conditioning was too big, and influence is running normally.Therefore, stop operation of air conditioner, prevent to make power consumption to exceed index.
By above explanation as can be known, feature of the present invention is the electric weight that uses by the network real time monitoring, and reduces the load of air-conditioning according to power value, reduces consumes power thus.Reduce operating load and mainly undertaken, and reduce consumes power thus by the operating frequency of conversion compressor.Therefore, in the section, when the electricity usage amount is high, reduce consumes power at one time,, improve the efficient of air-conditioning by the operating frequency that improves compressor if opposite electricity usage amount after a little while by the operating frequency that reduces compressor.
The method that just will change the compressor operation frequency among the present invention still also can adopt the control method that improves the compressor operation frequency in power consumption as embodiment after a little while.And, in described the 124th stage, after compressor shuts down, relatively make power consumption and the highest power value again through certain hour, if when electricity usage amount at this moment is lower than the highest power value, can restart air-conditioning.
