Description of drawings

Fig. 1 is a flow process synoptic diagram, and the preferred embodiment of air conditioner energy source charging method of the present invention is described.

Embodiment

Below by preferred embodiment and accompanying drawing air conditioner energy source charging method of the present invention is elaborated.

Consult Fig. 1, the preferred embodiment of air conditioner energy source charging method of the present invention comprises a weight setting step 1, a volume of traffic calculation procedure 2 and an expense calculation procedure 3.

At first carry out this weight setting step 1, this step is that each the fan coil value of being weighted in the air-conditioning system is confirmed, in the central control computer of this air-conditioning system, there is the air output weighted value of the fan coil of all size on the market, each specification is divided into again by force, in, weak (high wind, apoplexy, weak wind) three classifications, this step is that what to use in determining present air-conditioning system is the fan coil of which specification, and the data that have in should central control computer are gone to determine that this kind fan coil specification is strong at it, in, corresponding weighted value during weak air output operating position.

For instance, air output specification as a fan coil is 300 cubic feet of (CFM) (hereinafter to be referred as " 300 type fan coils ") of per minute, to the weighted value of this 300 type fan coil under the operating position of " weak " after the data that have in should central control computer is 1.00, " in " operating position under weighted value be 2.00, and the weighted value under the operating position of " by force " is 3.00.Air output as a fan coil is 400 cubic feet of per minutes (hereinafter to be referred as " 400 a type fan coil "), to the weighted value of this 400 type fan coil under the operating position of " weak " after the data that have in should central control computer is 1.50, " in " operating position under weighted value be 2.50, and the weighted value under the operating position of " by force " is 3.50.By that analogy the fan coil of each different model in the air-conditioning system being done weighted value by above-mentioned method confirms.But be noted that the above-mentioned weighted value number that discloses is a relative scale value, need are investigated voluntarily by system operator and are determined, so should not exceed with the explanation of present embodiment.

Carry out this volume of traffic calculation procedure 2 afterwards, the user reaches a sampling interval during can determining one to preset, and with this sampling interval each fan coil is carried out the user mode detecting in again during this is default, again that each time point is obtained weighted value addition just can obtain the total volume of traffic of each fan coil in during this is preset.

For instance and continue above-mentioned example, being made as during in the time of should presetting as this is 3 minutes, sampling interval was made as one minute, suppose to have in this air-conditioning system of being monitored one 300 type fan coils and one 400 type fan coils also respectively by under an X family and the Y family, this 300 type fan coil is first, second, during the 3rd minute operating position is respectively, by force, a little less than, and this 400 type fan coil is first, second, the 3rd minute operating position is respectively strong, in, a little less than, then the total volume of traffic of this 300 type fan coil in during this is default is 6 (being 2+3+1), and the total volume of traffic of this 400 type fan coil in during this presets is 7.5 (being 3.5+2.5+1.5).Be noted that fan coil be close or the situation of blowing under neitherly give calculating, that is to say that volume of traffic is zero.

Carry out this expense calculation procedure 3 afterwards, at first, the total electricity charge of order in during this is default are that A, maintaining expense are that total volume of traffic of B, each fan coil is that the total quantity of K, fan coil is each running expense W of n, each fan coil; Come again, with the total electricity charge (A) in this air-conditioning system is during this is default with (B) addition of maintaining expense and a total running expense (A+B), again with the total volume of traffic (K) in each fan coil is during this is preset divided by this air-conditioning system in the summation of volume of traffic of all fan coils

The result multiply by total running expense (A+B) again and just can obtain each fan coil each running expense (W) in during this is default, and design the formula of this W value of calculating whereby, this formula is: $W=(K/{\mathrm{\Σ}}_1^{n}K)\×(A+B).$

For instance and continue above-mentioned example, be 9000 yuan as the total electricity charge (A) in this air-conditioning system is during this three minutes default, maintaining expense (B) is 1000 yuan, then its total running expense (A+B) is 10000 yuan of two several additions.Therefore, the running expense (W) of this 300 type fan coil (X family all) in during this is default is: [6/ (6+7.5)] * 10000=4444.44 (unit), and the running expense of this 400 type fan coil (the Y family owns) is in during this is default: [7.5/ (6+7.5)] * 10000=5555.56 (unit), that is to say, this total cost of operation of 10000 yuan need not shared out equally in this X family and Y family, but charge according to the use amount number, solve the inequitable problem of existing charging way effectively.

The above-mentioned computation paradigm that comes across in the present embodiment is the illustrative of description do to(for) method of the present invention, it should longer (for example one month) during default in true the application, fan coil quantity in the whole air-conditioning system also can be more, even so, above-mentioned method stands good, so should not exceed with the example that present embodiment was disclosed.

Because the fan coil operating position in the existing air-conditioning system (air output strong, in, weak) be the central control computer that is directly connected to this air-conditioning system, so importing the method only needs directly this central control computer to be adjusted after the corresponding weighted value of decision, do not need existing air conditioning piping is done any change, just can carry out above-mentioned operating position sampling and corresponding calculating.How to adjust to reach operating position sampling and correlation computations to this central control computer is that symbolic animal of the birth year is worked as general technology for those skilled in the art, so do not given unnecessary details at this.

Conclude above-mentioned, air conditioner energy source charging method of the present invention, utilize the mode of weighting to represent the exhaust air rate and the corresponding behaviour in service of a fan coil, again each fan coil is carried out the sampling of fixed intervals and carry out corresponding volume of traffic and expense calculating, and then calculate not needing that the situation that existing air conditioning piping installs any additional element additional is issued to fair and rational consumption, so can reach purpose of the present invention really.
