Dispute at above-mentioned charge, so more accurate charging way is arranged, the calculated value that promptly utilizes electronic flowmeter is as the benchmark that charges, and the charging way of this kind electronic flowmeter is as the basis of chargeing according to the number of the frozen water flow in the comb in the central air conditioner system, though this charging way has following shortcoming than in the past more accurate:

1, the installing price of electronic flowmeter is high.

2, electronic flowmeter can produce one impingement flow in the moment that the dynamoelectric water valve switch switches in its pipeline, causes the flowmeter fault easily.

3, electronic flowmeter is when being out of order, and changes or maintenance must be carried out the work of dismounting, very difficulty in ceiling.

Because above-mentioned shortcoming, the object of the present invention is to provide a kind of public central air conditioner household cost allocation control method, it utilizes fan motor when running power demand and cold air ability that the proper relation that becomes a direct ratio is provided, and with the basis of this fan motor running power demand as charging, so that the utility power allocation of expenditures is more accurate and fair.

Another object of the present invention is to provide a kind of public central air conditioner individual user fee counter, it can gather the indoor temperature value, and selects air-supply or air-supply and air-conditioning by computer control.

The object of the present invention is achieved like this, a kind of public central air conditioner household cost allocation control method promptly is provided, the fan motor of central air conditioner turns round required power supply by being provided from source appliance, and each family is when using air-conditioning, main frame turns round required power supply from public power, the household cost allocation of described public power is to utilize the fan motor running power demand of indoor air conditioner to become the relation of a direct ratio with the air-conditioning ability, according to the conversion of fan motor running power demand and export a signal value to computer, described computer calculates the payable expense of each family actual use air-conditioning according to signal value again by electric power converter.

Public central air conditioner individual user fee counter of the present invention, comprise a central processing unit (CPU), the inductor of one sensing indoor temperature, one sets the function setting unit of temperature required value, one provides the controller from a source appliance and a control dynamoelectric water valve keying of fan motor running required drive, described CPU respectively with described inductor, the function setting unit, link to each other from source appliance and controller, the indoor temperature value that described CPU records the setting value and the inductor of function setting unit compares back output one corresponding signal to described controller, when controller is opened dynamoelectric water valve, public power starts the main frame air-conditioning, and start fan motor and Synchronous Transport Signal value to the computer household cost allocation by electric power converter, and controller is when cutting out dynamoelectric water valve, then by oneself power initiation fan motor.

The invention has the advantages that, can accurately calculate the expense that central air conditioner is used at each family, public occupants of building is paid by operating position.

Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:

Fig. 1 is a control flow chart of the present invention;

Fig. 2 is the process flow diagram of the present invention when blowing;

Fig. 3 is the process flow diagram of the present invention when cold air provides;

Fig. 4 is control principle figure of the present invention.

At first see also control flow chart of the present invention shown in Figure 1, this method can be according to the demand of user to air-conditioning, select air-supply or air-supply and air-conditioning respectively,, must blow and cold (warming up) gas could be transmitted when gas provides as cold (warming up), during as the selection air-supply, its power supply is by from source appliance supply (as shown in Figure 2), because of not using utility power, so there is no the expense allocation problem, the electric weight that pressure fan consumed does not need to transfer to computer by electric power converter and charges; And when the user selects air-conditioning to provide, the dynamoelectric water valve of main frame is opened (when cold air or heating installation are not provided, dynamoelectric water valve is closed condition), the main frame running makes interior frozen water (or hot water) circular flow of comb through user's indoor air conditioner comb, and blowing by fan motor.The user is provided air-conditioning, because the main frame running is to utilize utility power, and fan motor is still by (seeing also Fig. 1,3) is provided from source appliance, the cold air ability that wherein system provided just becomes a proportional relation with the running power demand of fan motor, therefore the time fan motor running power demand must conversion via electric power converter after, export a signal value to computer, the signal value that this computer then transmits according to electric power converter, each user costs is calculated at the branch family.
