How to calculate electricity consumption: tips

Each owner of real estate inevitably encounters such an item of costs as utility payments. Some owners may have suspicions that the sources of life-support supplied to the apartment or house are over-spent for a month. . To be able to control this process, it is necessary to know the technology how to calculate electricity consumption .

At the same time, it is possible to identify devices that cause large accounts. When making the correct calculations, you can develop a plan to reduce costs. The technology of this process will be discussed in detail later.

Modern technology

, необходимо ознакомиться с некоторыми особенностями, которыми обладает современная электротехника. Before calculating energy consumption , it is necessary to familiarize yourself with some of the features that modern electrical engineering has. Scientific developments in the search for economical technologies have led to the creation of instruments, instruments that consume significantly less energy than their predecessors.

For example, the Soviet refrigerator required 2 times more energy resources than modern varieties with similar characteristics. Therefore, the first thing you should pay attention to is what appliances are installed in the apartment. If they are an old model, it is necessary to develop a plan for their gradual replacement with new equipment.

Today, there is a certain scale for determining the energy-saving qualities of devices. It includes the letters A, B, C, D. The first letter indicates the most economical characteristics of the device. If the device shows the letter G, it is a technique that consumes a lot of electricity.

Load calculation

There are several ways to calculate the electricity consumption in the house. The first of these involves determining the power of household appliances. , следует рассмотреть подробнее. How to calculate the power consumption by power , should be considered in more detail.

For the presented technique, it will be necessary to create a table in which all electrical consumers that are in the apartment will be listed. Next, you need to write out, according to the manufacturers instructions, the power of all the devices.

Then, summation of the capacities is performed. As a result, it turns out how much electricity all electrical appliances require, if they work simultaneously. However, this situation is extremely rare. Each type of equipment works only a certain amount of time. Therefore, real consumption differs significantly from the nominal value declared by the manufacturer.

Calculation formula

There is a certain technique that helps to understand how to calculate electricity consumption. при этом довольно простая. The formula is quite simple. It looks like this:

Р = М * В * С, where Р - the electric power consumption by the consumer for a month, М - power of the device, В - the operating time of the device per day, С - the number of days that the equipment worked.

In the table, the real values of consumption for each electrical appliance are added next to the power. Calculations are made on the basis of testing, as well as data of the instructions of each device.

Application of a special device

, следует рассмотреть такой вариант, как применение специальных приборов учета. Asking the question how to calculate the power consumption by the equipment's power , one should consider such an option as the use of special meters. There are stationary and local varieties of similar technology.

In the first case, the meter is installed directly in the switchboard. It measures the power consumption of all devices connected to a common point of power.

Local devices are designed to control each individual unit of equipment. On the one hand, you can get real information about the consumption of some kind of electricity device, but on the other - you will have to consider the total value of all measuring devices. The best option hosts the house independently, at their discretion.

Main Customers

In a modern house or apartment there are several main electricity consumers. They work almost every day, thereby making up the bulk of the total cost of paying for energy.

First of all, it is necessary to allocate a refrigerator. It is included in the network 24 hours a day. Its work, of course, is controlled by special devices. But this is one of the main consumers of electricity. Next on this list is an electric boiler (if it is in the apartment). It also takes a significant place in the total costs. After these two devices are followed: computer, TV, and lighting.

, а также работу всех бытовых приборов, необходимо уделить особое внимание основным потребителям. To understand how to calculate the electricity consumption for lighting , as well as the operation of all household appliances, it is necessary to pay special attention to the main consumers. It should also be noted that in the heating season, many owners of this list are supplemented by electric convectors, radiators and other similar equipment.

Costs of lighting

It should be noted that when there is an over-expenditure of electricity, as well as the need to take measures to reduce electricity costs, first of all, it is necessary to pay attention to the type of devices used in everyday life. A bright example can be lighting.

, следует сравнить разные устройства. To understand how to calculate the power consumption by lamp power , you need to compare different devices. Older varieties of lighters consume significantly more resources. For example, for lighting a small room, incandescent lamps with a power of about 100 W were used earlier.

Today, other devices are used for this purpose. The energy-saving lamp is capable of delivering the same radiation flux as the presented device, but consuming only 15 watts.

If you add the sum of all the old customers used in the apartment, and then calculate the savings from the use of LED, fluorescent lamps, the choice will become obvious.

Fridge

Today there is, perhaps, no family that would not use a refrigerator. This equipment is considered one of the main consumers of electricity. Therefore, when developing it, technologists try to find the most economical principles of its work.

Many manufacturers indicate the average value of energy resources that a refrigerator can consume per year. This number for small models is about 250 kW, and for volumetric models - up to 500 kW. Monthly consumption, respectively, is 21 and 45 kW.

Other home appliances

, необходимо рассмотреть средние значения, потребляемые бытовой техникой в обычных условиях. To make it easier to understand how to calculate electricity consumption , it is necessary to consider the average values consumed by household appliances under normal conditions. The average computer consumes about 30 kW per month for about 2 hours a day.

The washing machine can consume at 4 washings per month at medium modes of about 10 kW. But with increasing frequency and intensity of its actions, this indicator will increase.

An iron and an electric kettle stand practically on the same level as energy consumption. They are not used so often. But, even boiling the kettle 5 times a day, for a month you can pay for 20 kW of electricity. Iron, which is applied 6 times a month, is able to consume 15 kW for 30 days.

These facts should be taken into account when calculating electricity consumption. If the owners began to get big bills for energy, you need to know how to calculate electricity consumption. This will help reduce costs in the future.
