Embodiment
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The present embodiment is adjusted as example take the carbon footprint of product power consumption, carbon footprint is a kind of method of analyzing greenhouse gas emission quantity, and it refers to the whole life cycle of an activity, a product (or service) or a certain geographic range is directly interior and the indirect CO2 emissions (or CO2 equivalent discharge capacity) that produce.Wherein, the use of product carbon footprint label becomes a kind of international trend, and increasing enterprise requires supplier that the carbon footprint value of product is provided.And in carbon footprint calculation process, the greenhouse gas emission that power consumption causes is the important component part of product carbon footprint.Therefore this enforcement is applied as typical take the calculation process of product power consumption carbon footprint, but the present invention is not limited only to the accounting of product carbon footprint.
The layout of Tu3Shi A factory, the product sequence of Tu4Shi A factory, following table 1 is the production equipment information table of A factory, table 2 is current consuming apparatus information tables of producing auxiliary and shop office, table 3 is administration office current consuming apparatus information tables, and in January, 2012, power consumption was 41680kwh.
Table 1
Table 2
Table 3
The present invention carries out the implementation case study of the inventive method take above data as analytic target.In conjunction with Fig. 2, concrete calculation procedure is as follows:
Allocation step one: according to A plant data: total power consumption calculates with the power consumption 4768kw in January, 2012; The information such as title, number, rated power and the configuration production capacity of the current consuming apparatus that in factory, each workshop comprises and power consumption equipment are as table 1, and the current consuming apparatus title of shop office and Administrative area, number, rated power, working time every day are as table 2 and table 3.
Allocation step two: be then three levels by data allocations: production equipment power consumption, production utility appliance power consumption and operation equipment power consumption, Fig. 1 illustrates three levels of Data Collection.The ratio of utilizing rated power × equipment number × darg time, formula is as follows:
Allocation step three: to each equipment, be also to utilize the proportionate relationship of rated power × equipment number × darg time to distribute, as formula (4) by the data allocations of the first level; If this device fabrication multiple product, also needs power consumption to be assigned on every kind of product, method is to distribute according to product yield ratio, concrete formula following (5).
Allocation step four: the second level power consumption is assigned to every kind of product, utilizes production time scale to distribute, concrete formula following (6).
Allocation step five: last, tri-layer is assigned on every kind of product to concrete formula following (8) according to the proportionate relationship of output.
Allocation step six: the power consumption of three levels is added to the power consumption that obtains every kind of product, then divided by output, obtains the power consumption of unit of certain product, concrete as formula (9).
Allocation step seven: unit product power consumption is multiplied by electric carbon emission coefficient and can obtains single unit product power consumption carbon footprint of planting product, concrete as formula (10), the total power consumption that wherein Q (x) is certain product, unit is kwh; f efor the carbon emission coefficient of institute of A factory electricity consumption, be 0.8244kgCO 2e/kwh.
ECF x=Q(x)×f E (10)
ECF a=3.433×0.8244=2.83kgCO 2e;
ECF b=2.392×0.8244=1.972kgCO 2e;
ECF c=2.713×0.8244=2.237kgCO 2e。
