Energy consumption — important part of modern life. There is a wish to overpay for excess kilowatts to nobody therefore for many owners the question of how to calculate optimum quantity of necessary electricity is particularly acute enough. It will help to use, first, more fully available illuminating and electric devices, and secondly, to avoid inefficient expenditure. It is the best of all to start calculation of energy consumption before the planned repair. It is possible to shift wiring at once, to buy the necessary types of bulbs or household appliances.
Instruction
1. Contrary to common stereotype, at all not bulbs give the main loading in energy consumption. Even the "stovattka" consigning to the past at recalculation are not such gluttonous if to compare them, for example, to the washing machine or especially the electric heater. It is enough to tell that for working hours the washing machine consumes as much electricity, how many 20-25 at the same time working 100-watt bulbs.
2. So, that in the house the most costly from the point of view of consumed energy? Here the table with the most widespread types of electric devices is provided. In it the power and approximate daily operating time of each of them is specified. If the device is going to be used, you consider quantity of the electric power consumed by it. If it is not planned, just you strike it off the list.
3. After that you multiply kilowatts for hours. The turned-out digit will reflect cumulative daily consumption of electricity all household household appliances. It is necessary to realize that digit this rated. For example, in family with the small child the washing machine works almost round the clock, so, it is necessary to correct digits taking into account all specific circumstances.
4. After that start calculation of power of lighting equipment. Here everything is slightly simpler. Each owner intuitively knows how many watts are required for illumination of any given space, whether it be the living room or desk. As a last resort it is possible to walk round the house with "carrying" and to try different options of arrangement of bulbs. It is clear, that the bulbs located close to walls, partially closed by furniture or located low will give the smallest efficiency. At the same time it is occasion to think of arrangement of furniture so that it did not block lighting equipment and daylight too, it is additional working hours of bulbs.
5. Having counted bulbs and having defined their future places, it is possible to start calculation. Let's say here what you have counted: - Chandelier in the living room (3 bulbs on 100 W) - the Chandelier in the bedroom (3 bulbs on 60 W) - - the Surface mounted luminaire in kitchen (150 W) - Bulbs in the bathroom (3х50 W) - the Bulb in toilet (50 W) - Bulbs in the hall (2х45 W) - the Bulb in the storeroom (45 W) - the Desk lamp (45 W) - Illumination of kitchen cabinet (3 bulbs on 15 W) - Illumination on extract (50 W) Put Lamps over bed (2 bulbs on 30 W). 1165 W — the total power of luminous sources turn out. Now it is necessary to estimate how many each bulb will burn in day. It depends on the floor, season, preferences and economy of the owner. Average digit is as follows: 6 hours a day will burn about a half of the available bulbs. That is daily consumption of lighting equipment for the described apartment will be approximately ravnym1165/2 x 6 ~ 3.5 kWh
6. To this digit add earlier found out consumption of household appliances (it is admissible, in our case it is 5 more kW) and increase for 30 days. Leaves: (3.5 + 5) x 30 = 255 kW / cheto will also be rated energy consumption of the specific apartment, knowing which it is possible to start repair and planning of expenses quietly.
