If you have decided to save energy with the resources they already have or are buying an appliance and want to know how to choose one that uses energy more efficiently, we produced this guide is not trying very technical and easy to interpret. You can also estimate that it may be desirable to change any device with a more efficient, not only to conserve energy, but also because the cost is amortized quickly by consuming less energy and therefore less money.
is important to note the election, responsible use, reuse and / or recycling of goods, then, in almost all cases, resources and energy used to produce them. How
Determining the Power?
If you already know which is the consumption of each device, skip this paragraph. Each appliance has consumer information in the manual, usually at the end of it where he talks about the technical specifications. If you do not have it, you can be on the same device or label indicating chapita consumption. In major appliances (refrigerator, washing machine, dishwasher) is usually not the eye but that is behind or in older aircraft is a label that is on the same engine.
The energy is expressed in Watts or kW (1 kilowatt = 1000 watts). The work produced by an electrical appliance, expressed in kWh (kilowatt = hour) and represents the energy of 1 kilowatt used for one hour.
For example, a common fan consumes some 200 watts and you turn it on some 4 hours a day for about 120 days a year, consumption of it will be:
(200 watts) x (4 hours per day) x (120 days) / 1000 = 96 kWh per year
If you want to know how much money represents, you can look at your electricity bill which is the cost you are paying for the kW and multiply, and so will the annual expenditure. Sometimes this is difficult to discern, by taxation, contributions, etc..
IMPORTANT: The cost you pay for the kWh may vary by consumer range in which you are, the companies that provide energy tend to "punish" charging high consumption of kWh value to surplus the greater value .
IMPORTANT 2: Consumption in kWh indicated in each unit, usually reflecting the increased consumption. For example, a radio volume up, the washing machine while heating the water, the refrigerator while the engine is running. In the case of a refrigerator, consider all the time it is plugged into the wall divided by 3, in normal use would be about 8 hours a day.
CAN NOT FIND THE CONSUMPTION IN WATTS (WATTS)
If you do not have consumer information, you can calculate it from the current in amperes. May not indicate how many watts of power consumption, but if, for example 2A (2 amps). Then the power consumption in watts is calculated by multiplying the amps by the line voltage (110v or 220v depending on country).
Example:
An iron -> 6A (amps) -> 6A x 220V = 1200 watts (or 1.2 kw is the same).
If you can not find the watts or amps, you can measure with a clamp meter is a tool that any electrician has. These measure the instantaneous consumption and some with the impression of a graph on a tape measure for several hours. So you can see that any triple engine uses to boot in normal operating conditions. ENERGY LEAK
If you suspect a "loss" in any unit or any part of the installation of your home because its consumption has increased too dramatically, you can check disconnecting one by one and observing the progress of their meter, this can be done with the help of another person to not have to walk too much (it will make you walk the same). If after you have disconnected all devices the meter is still moving, it means that your Installation is leaking and should be checked by an electrician. What is the sign-a loss? Means there is leaking current to ground by a wall or floor by a driver who has lost their insulation or there is too much moisture and condensation in a pipe.
