The disclosures of PCT/IB2009/053135 and P200802159 are each hereby incorporated herein by reference.
TECHNICAL FIELD OF THE INVENTION
The invention refers to a device for measuring power consumptions and the respectful performance with the environment, from the measured power consumptions and from the residue production, in a power-consuming unit, a comfort unit (houses, communities, hotels and restaurants, spare time spaces, sport spaces, private and public motor vehicles, and goods vehicles, etc.) or a production unit.
The measurement of this respectful performance or not will be carried out by what we call “ecological parameter”, from the measurements of power consumptions (direct consumptions) and of residues and wastes generated (indirect consumptions).
BACKGROUND OF THE INVENTION
A lot of kinds of programmable logic controllers (PLC) are known, in which, from state variables, the outputs of a system are determined (e.g. electrical or pneumatic, etc.) or another kinds of devices that, from inputs, calculate the values of parameters of interest. Examples of these devices can be the known analysers of the electric mains that, from voltage, current intensity and imbalance signals, calculate the electric power consumed by an installation.
However, in the current art no device or apparatus that calculates ecological parameters or magnitudes are known, from power consumption and waste production data in installations, if we define such parameters or magnitudes as a deviation of an optimal work point, defined by an authority. E.g. in which the emissions of COx or NOx are the minimum possible according to its use.
The present invention has the objective to provide an apparatus that fulfils this gap in the current art.

        an input of combustible gas or liquid flow, from a second flow meter of combustible gases or liquids;
        an input for measuring the electric power, from a counter or analyser of the electric mains; and

DETAILED DESCRIPTION OF THE DRAWINGS
In said drawings it can be seen the constitution and way of the device for measuring power consumptions and for calculating ecological parameters from the measured power consumptions, directly and indirectly.
The function of the device of the invention is to measure the respectful performance or behaviour with the environment of a “power-consuming unit”. The “power-consuming unit” object of the measure of the possible different power manifestations consumed can be: a house, community (hotel, sports centre, residence, sport spaces, shops, department stores, leisure halls, office buildings and studies, administration centres, etc.), transformation centres, garages, warehouses, motor vehicles or transportation means, private or public.
The basis of the operation will consist in the comparison between the basic actual power flow required by the user for their comfort with the normal consumptions of the current regulations (e.g. UNE, ISO standards, etc.) and/or those recommended by official administrations of the place and/or statistic data of normal power consumptions and wastes (hereinafter “typical consumptions” including flows of power consumptions and wastes by person or by own unit of a preset population).
For this comparison, the proposed system will calculate an ecological parameter as an adjusted mean of the sum of deviations of each value of power consumption measured with respect to its corresponding reference value.
To this end, as seen in FIGS. 1 and 2, the device 1 of the present invention is constituted by an apparatus that has a carcass or shell 2 that includes the following elements:

    
    
        a module for introducing data 3, provided with inputs of power consumption values E1, E2, E3, E4, of magnitudes, measured with corresponding measure apparatuses C1, C2, C3, C4;
        a keyboard 6 for introducing data and selecting menus, in particular data of the waste production;
        computing means 4, which receive the data from the module for introducing data 3 and the keyboard 6, and which are provided with a processor that includes a calculation algorithm for an ecological parameter from the measured power consumptions and from the introduced data; and
        a display screen 5, communicated with said computing means 4, to display the calculated ecological parameter.
    
    


The apparatus is provided with an electrical source 8, as it can be seen in FIG. 1.
To introduce values of the waste production one of the inputs E4, digital o analogical, can be used, from a weight apparatus, or they can be introduced manually through a keyboard 6.
The device 1 can be complemented with an input module 90 for a data bus 9 of a domotic network, and an USB input 70 for a serial data bus 7, or equivalent means.
In FIG. 1 a device particularly devised for special application in buildings (houses, hotel, sports centre, residence, sport spaces, shops, department stores, leisure halls, office buildings and studies, administration centres, transformation centres, garages, warehouses, etc.) is shown. The shell 2 comprises at least the following inputs:

    
    
        an input for the water flow E1 from a corresponding first water flow meter C1;
        an input for the flow of combustible gases or liquids E2, from the second flow meter of combustible gases or liquids C2;
        an input for measuring electric power E3, from a meter or analyser of electric mains C3; and
        an input for measuring the weight of the wastes E4 from a scale for weighting wastes C4,
    
    


through the corresponding ports.
The number of inputs will be according to the complexity of the installation. E.g. an industry can be provided with several devices of this kind, each associated with a corresponding section or unit of factory, warehouse, office, etc.
In FIG. 3 is shown an embodiment particularly devised for automobiles, in which the device comprises an input for fuel flow E6, from a flow meter C6 of fuel, associated with the fuel deposit 15; and an input of exhaust gases flow E5, from a corresponding flow meter C5 of exhaust gases from the exhaust system 14 of the motor 13 of an automobile 12. In this case, by the keyboard the flows of production of wastes of the automobile are introduced manually, e.g. rubber wastes from tires, oil wastes for the motor, coolant liquid wastes, liquid wastes from closed circuits and metal wastes.
The device has an input 10 to collect, optionally, the information from a gas analyser 11 (FIG. 3), to measure the emission levels of gases and particles. The device 1 compares the result obtained with the levels admitted by the current regulations.
The algorithm of the computing means 4 calculates the total basic power flow obtained by the evaluation of the flows of the measured power statements E1, E2, E3, E4, E5, E6, etc. referred to the number of people which use the unit to be measured in each trip. The calculation algorithm integrates all the trips of a time period to be defined or the accumulated total.
Each flow has an incidence in the environment: the water consumption reverts in its exploitation, the fuel consumption is associated to the direct emissions of CO2, NOx, . . . , the electric consumption to the indirect emissions of CO2, NOx, . . . , and the waste production with indirect environmental impact, by the quantity of paper, glass, organic material, plastics, oils and greases, rubbers, metals, . . . expressed in kg that the unit consumes per time unit and please who enjoy the comfort of said unit, to be compared with preset consumptions and wastes. These data, once treated by the algorithm, give as result an ecologic parameter (here denoted as “ecocom”), which is the measure of the conduct that respects our environment, to provide integral or combined or individual “ecocoms” of the comfort or production unit.
Regarding the presentation of the results, from said comparison the actual percentage of power consumption with respect to the preset consumption is obtained, indicating if the performance if respectful (equal to zero or higher) or abusive when it is negative. Both deviations are measured as a percentage. The percent unit of each flow is called positive “ecocom”, if the result is respectful or negative if it is not. The algorithm of all the flows provides the integral “ecocom” of the unit. As there can be difficulties to receive all the flows, the algorithm of the ecometer could provide only “ecocoms” of water exploitation and/or direct gases emission and/or indirect gases emission and/or waste production. It is also possible to measure only those flows the public administration considers suitable to pay ecotaxes, evaluating a specific pack (which can be called “administrative ecocom”).
The results are presented in a permanent way in a screen 5, indicating the periods of time on which they are based: the day, week, month accumulations, etc. or others, such as those consumed by trip in the case of vehicles. To know better the power exploitation, by a menu the “ecocoms” can be displayed (day, week, month, . . . ) of exploitation of the different power sources in the screen or to pass to other successive ones with the direct or indirect emissions or waste production.
As stated previously, if the consumption of only one or several flows are calculated for installation difficulties, the permanent screen shows that they are individual “ecocoms” by power source or waste, combined or integral.
Regarding the installation of different measuring apparatus C1, C2, C3, C4, C5, C6, etc., the water flow meter C1 is placed downstream the company meter and upstream the home key, with the possibility to emit impulses or analogical or digital or light signals. The same applies to C2, flow meter for combustible gases or liquids, to C3, electric measuring equipment in the general board of the unit, to C5, in the case of exhaust gases, and to C6, in the case of fuel flow of an automobile. The same can be said to the flow of waste production E4, which will be from a scale C4. The emission of information can be wireless or wired. In the case that there is no installation, by the keyboard 6 the flow data can be introduced manually.
Algorithm for Calculating the Ecologic Parameter
It results from the adjusted arithmetic mean of all the quotients between the absolute value of actual flows (E1, E2, E3, E4, E5, . . . ) that enter in the power-consuming unit object of the measure of the different possible power statements, with respect to their flows or corresponding reference values. The absolute value of the actual flows is taken because the input power consumption has a sign opposed to a waste, which indirectly is associated to another external power consumption;
therefore, as the contributions of each factor is the interesting part, all are taken in flow absolute value, no the quotient of flows, not being compensated to each other.
It is defined:
1—Flow of an actual input power statement (E1, E2, E3, E4, E5, E6 . . . , generally Ei): As the power quantity consumed by the time unit of that power statement, by user of the unit to be measured. E.g. the drinkable consumed in a home is a power flow because it is obtained from the nature with transportation, purification cost . . . ; these power costs are environmental costs associated with that consumed water. The combustible liquid and gas flow consumed is another actual input power flow associated with the direct emissions of CO2 and others to the atmosphere. The electricity consumption is another power flow associated with the indirect emissions of CO2 and other not desired gases. The wastes are also indicative of the environmental impact and they indicate indirectly a power expense. E.g. it is also an input power flow the quantity of glass we waste for identical reasons, but not those that we buy and remains for the development of the activity in the unit. Also with the paper, the organic material, the containers, the spare parts from repairs, etc.
2—Preset flows (Ct): They would be the average power consumption desired or recommended by the public administration of the zone where the activity of each unit to be measured is developed. If there is no environmental policy defined by the administration, standard consumptions or statistic data of consumptions are taken, inputs as consumption and outputs of wastes per resident or per production unit.
3—Adjustment coefficient (Cpd): Each coefficient designs a deviation percentage with respect to the preset consumption of consumed power statement. But not all have the same importance according to:
3.1. Habits regarding the consumptions of the unit. In certain regions there are power statements that have an important weight due to the proximity to the resource, subsidized prices or no other sources . . . . In these situations it must take into account the suitable specific weight that the administration determines or the statistical data. In the case of a motor vehicle, the water consumption will be dismissed, but not the fuel liquids or gases consumptions, the oil and grease wastes and rubber and metal wastes.
3.2. The power policies of the zone. According to the administration of the place and attending if to the environment conduct is associated a tax; these quotients must be adjusted depending on which deviations the administration could reward or punish.
3.3. Practical ends. These coefficients can be zero, because the contribution of said consumption is so low that is dismissed, according to the cost of its measure. E.g. the quantity of organic wastes of an electric train.
The adjusted coefficients are between 0 and 1.
Hence, the ecologic parameter (or “ecocoms”, in %), for “n” magnitudes of power consumption or wastes, is calculated applying the formula:

Wherein n is the number of power sources or waste variables to be measured (with adjustment coefficient different from zero) and p the people who enjoys the comfort of the unit to be measured.

Interpretation of the Results

The result is a percentage that when is close to zero the performance is desirable, but if it is negative and far away from zero, the performance of this unit is not respectful and the distance to zero is the degree of the separation from the desirable performance, and therefore it can be penalised and the penalization can be measured. Lastly, if it is positive the performance is excellent and the separation from zero is the measure of its environmental excellence.
The device for measuring power consumptions and the respectful performance, according to the present invention, can be used for the calculation of an ecologic parameter, which can be used as basis for the application of called ecotaxes by the administration.
