Tip 1: How to determine electricity consumption

Tip 1: How to determine electricity consumption



On consumption electric power many factors influence. The largest part of the energy usually goes to the work of lighting equipment, therefore, measures to reduce expenditure It is better to start electricity in this category.





How to determine the power consumption


















Instructions





1


To determine the flow electric power, it suffices to use the formula: W = P · t · T, where: W is the flow rate electric power in kWh, P - the power consumed by the electric receiver (electric appliance) in kW, t - the operating time of the electric receiver per day in hours, T - the number of days of operation of the electric receiver.





2


In turn, the power consumptionis calculated by the formula: P = Pobs · K, where: Pobsh - total installed capacity, K - demand factor. The value of the coefficient is taken based on the number of electric receivers, the volume of the load. It can be taken from the reference material.





3


So, we can conclude that the amount consumed electric power Two factors directly influence: power and time of use. For consumers, electricity is not only an economic necessity, but also a commodity that can and should be saved. This will not only help save money for other needs, but, much, much less - save the planet from the destruction of resources. After all, in order for the power plant to generate electricity, you need to burn a certain amount of fuel or wood.





4


Unfortunately, to calculate the consumption of household electric power with great accuracy is very difficult, becausesome devices have different functions, during which they consume a different amount of energy. For example, the cycle of the washing machine operation includes a set of water, heating, washing, drying, etc. Therefore, the figures are approximate. In order to achieve a certain accuracy, automatic counting systems electric power, in other words, counters.





5


The most energy-consuming household appliance is, of course, a refrigerator. He, as a rule, works whole days and consumes not less than 30% of all electric power. Modest in comparison with it arewashing machine, vacuum cleaner, iron, etc. When buying a new electric appliance, you should immediately know about the power it consumes. Usually, the more "sophisticated" the technique, the more it consumes. To orient buyers, technical instruments are divided into energy efficiency classes: A, B, C, D, E, F and G. The most economical technique belongs to class A, B and C.





6


Often consumers use devices economically, but forget about another absorber electric power - an electric light bulb. Do not leave the light where it is not needed, and the light bulbs themselves should be replaced with energy-saving ones. They are much more expensive than conventional ones, but they will pay off their energy costs with their longevity.




























Tip 2: How to find out the power consumption



If you installed an electric meter and youit seems that his testimony is not accurate, it is necessary to check it for certainty. To do this, it is not necessary to remove the seal, because everything is much easier.





How to find out the power consumption








Instructions





1


Method one. Each meter has its own accuracy class on the dashboard. The accuracy class is the maximum permissible deviation of the instrument reading from the true value of the consumption electric power. Therefore, to check the counter forCorrectness of indications, disconnect all devices in the house, leaving on the counter for a while only one load, the approximate value of which you know. If the meter reading is very different, it means that the device with a defect and it needs to be changed.





2


Method two. Now there are a lot of useful programs that help you learn consumption electric power. They are easy to use. First, install the program you like on your computer.





3


Check the computer for the correctness of its use. To do this, as a device for checking for consumption electric power select the computer itself.





4


Enter the total time for using the PC in the window that appears on the screen. After that, the program will provide you with a variety of reports that will provide information on payment per hour, monthly consumption electric power computer, monthly or hourly pay for consumption electric power.





5


Way the third. It's the simplest. Take the reading of your meter and take the previous readings from it. Divide the received figures by the monthly tariff to find out how much you pay for 1 kilowatt electric power. The difference between the current meter readings and the previous ones will be the value you needed to know.












Tip 3: How to determine the power of a new refrigerator



The power consumption of the refrigerator is calledThe maximum possibility of electricity consumption for the most efficient operation of the unit. When buying a new device many owners are interested in its real, and not specified in the instruction capacity - so how can you determine it yourself?





How to determine the power of a new refrigerator







All about the power of the refrigerator

From the power of the refrigerator directly dependsuch characteristics as energy efficiency, energy efficiency, overall productivity, additional functions and freezing capacity. Energy costs are the nominal amount of electricity that the unit spends on its operation, whereas energy efficiency is a rational amount of energy consumed by the operating refrigerator. The power of freezing the refrigerator is the ability to freeze a certain number of products per day. The capacity of the refrigeration unit depends on its external dimensions, the compressor and its capacity, fan capacity, seal insulation and use of additional functions. Various manufacturers produce refrigerators whose freezing capacity varies significantly. The class of the unit is usually written on the factory label - the letters A, B, C, D, E, G indicate the degree of its energy efficiency. Refrigerators with label A, B or C represent an economical class, with the letter D an intermediate value, and E and G represent a large power consumption of the unit. Today, the market is mainly dominated by refrigerators A, B and C-class.

Know the power of the refrigerator

To measure the power independentlyof a modern refrigerator, you can use a multimeter, measuring it with the indication of the refrigerator chain when the compressor is running. The values ​​obtained should be multiplied by the mains voltage (220V), however, it should be taken into account that when the compressor is started, a current exceeding the nominal value of the voltage by two or three times will flow along the circuit. Therefore, the obtained readings should be multiplied by 3 - if the power is measured for the purpose of connecting the voltage regulator, the required power of the stabilizer should also be added to the multiplier. The average power of the modern refrigeration unit stated in the manual is traditionally not more than 250 W, but after measurement it can reach 500 W. To reduce the energy consumption of the refrigerator, you need to open its door briefly and not too often. Also, the air heated by its rear wall should circulate completely freely, so that the unit is less likely to shut off and consume less energy. To do this, the ventilation grilles of the refrigerator must be kept open. Food before being placed in the refrigerator must be cooled, and accumulated ice on the evaporator of the freezer - remove at least once a month.








Tip 4: Herbicides for the destruction of weeds: varieties and uses



Pesticides are designed to protect plants from pests and destroy weeds, but they do it in different ways. There are two large groups of these "defender-destroyers" - contact and system.





Herbicides are contact and systemic







The first group is contact pesticides. These substances kill pests and weeds by direct contact with them. Systemic pesticides penetrate into the plant tissues and attack it from the inside, and the pest then, the code, he decides to start eating the plant. According to the classification system, plant protection products are divided into eight categories - by the objects of their application: - insecticides destroy insect pests - karicides fight mites - nematicides protect the plant from nematodes - rhodonticides help to destroy rodents - fungicides protect against fungi - herbicides struggle with weeds, - arboricides protect against woody weeds, - bactericides are responsible for fighting bacteria. The best pesticides for controlling weeds are "Linthur", "Sniper", "Launtrel" and "Roundup" .

"Linthur" and "Lontrell"

"Linthur" and "Lontrell" - these are effective anti-tankherbicides of systemic action. They help protect the lawn from clover, dandelion, plantain, buttercup, mountaineer and other weeds. Complete disappearance of weeds is guaranteed for 2-4 weeks, and the first symptoms of weed loss will appear in 8-10 days. These herbicidal preparations are available in the form of water-dispersible granules, which readily dissolve in water and do not have a smell.

Roundup

"Roundup" refers to universal herbicides. It is intended for the continuous or directed destruction of "surviving" perennial, dicotyledonous weeds and gramineous weeds. It is used most often when developing a new site or preparing land for planting, to remove undesirable vegetation along the buildings, fences, paths.

"Sniper"

"Sniper" is a herbicide of directed action. The treatment with the drug really reminds us of point-like shots of a sniper rifle: the liquid from the vial with the applicator is applied directly to the leaves of the weeds. This is a contact herbicide. After application, the "Sniper" spreads over the organs and tissues of the plant, as a result of which all parts of the weed plant die: both above-ground and underground. When using herbicides, it is necessary to strictly follow the rules. Children and adolescents, pregnant and lactating women, sick people should not be allowed to work with poisons. Preparation of the solution and work with the preparations are carried out in special protective clothing or a rubber apron, rubber gloves, goggles and gauze wool respirators, protecting the nasal and oral cavity from penetration of harmful vapors. Herbicides are hermetically sealed, separate from food products. The dishes, in which the solution was prepared, is buried in a specially prepared pit. Hoses, sprayers and pollinators are carefully washed and cleaned. Pesticide solutions are prepared before use. Process plants in the evening or in the morning. Spraying is done by a fine suspension of aqueous solution in the absence of abundant dew and rain. Pollination is produced by a thin powder layer after dew.








Tip 5: How much power do you consume?



Consumption of electricity is one of the most important parameters, which should be paid attention when choosing and buying a personal computer. It depends on the power of the computer and the load on it.





How much power do you consume?







Consumption of electricity by personalthe user's computer is directly related to the power of the components that make up the PC itself, as well as the degree of its utilization by various software. Thus it turns out that, for example, if you buy a powerful power supply, it will consume much more electricity. It is worth remembering that the more processes will be launched on a computer, the more power will be consumed, respectively, and electricity will be consumed much more. The purpose of running processes is much more important, that is, if you just work in a browser, then electricity will be consumed much less, and if you play games or work with demanding graphics applications, then more. As a result, it turns out that all these three factors (power unit power, number and complexity of processes) directly affect the power consumption.

Computer power consumption

Standard office system unit with workingoffice applications mainly consumes from 250 to 350 watts per hour. A more powerful computer, on which graphics applications and games are launched, will consume more electricity, on average - 450 watts per hour. Do not forget about I / O devices that also use electricity. Modern monitors today consume 60 to 100 watts / hour. As for printers and other peripherals, they consume about 10% of electricity, that is, they use about 16-17 watts.

average cost

If you calculate the average costelectricity consumed by a personal computer per month, then it is enough to multiply its cost by 30 days. For example, if you take the maximum cost of one kilowatt-hour at Moscow rates, it turns out, about 3.80 rubles. Thus it turns out that if you use a standard office computer at the limit of its capabilities during the whole month and when consuming electricity from 250-350 watt / hour will cost a month 950-1330 rubles (if you work at your computer for more than 8 hours every month) . The gaming computer, accordingly, will spend much more electricity, hence, money for the use of such a device will be spent more. Of course, the final amount of consumed electricity depends on how long the computer will be used and in what conditions.








Tip 6: Which way to generate electricity today is less expensive



Scientists have been trying for many decades to developthe cheapest sources of electricity. After all, inexpensive electricity is affordable goods and a high standard of living for people. But on the way of obtaining cheap electric energy there are numerous obstacles, so the search is still continuing.





Sayano-Shushenskaya HPP







Hydroelectric power stations

The cheapest for today is consideredelectricity generated by hydroelectric power plants. Expenses for the construction of hydroelectric power stations are essentially one-off. The hydroelectric power plant pays off quickly enough, after which the electricity is generated practically without any costs. Among the most powerful hydropower plants in Russia, Sayano-Shushenskaya with a capacity of 6,400 MW and Krasnoyarsk HPP - 6,000 MW built on the Yenisei, and the Bratsk HPP with a capacity of 4,500 MW on the Angara.

Nuclear power plants

The cost of electricity generated bynuclear power plants is comparable to the cost of electricity from hydroelectric power plants. At the same time, nuclear power plants require the cost of purchasing nuclear fuel and providing security, they require highly qualified personnel. One of the advantages of nuclear power plants is the presence of a large amount of waste water vapor: after it gives up its energy to the generator, it can be used for domestic needs. For example, for heating houses and hot water.

Thermal stations

Thermal power plants, as a rule, work oncoal, small stations can use gas or fuel oil. The cost of electricity they receive is higher than that of nuclear power plants and hydroelectric power plants. Nevertheless, it is at the thermal power plants that currently produces the bulk of the electric energy. The main advantage of thermal power plants is high safety. Like nuclear power plants, heat generates a large amount of steam used for heating premises and other household needs.

Wind generators

One of the safest in terms of ecologyways to generate electricity - the use of energy of motion of air masses. In places with constant smooth winds, wind generators can provide fairly cheap electricity, the payback period is several years. The most important point is that wind generators do not need fuel, the energy they produce is really "free". And while it is still more expensive than electricity produced in other ways, the construction of windmills by many countries is seen as an important alternative source of electricity. In Russia, in particular, it is planned to build powerful wind generators on the Azov Sea in the Yeysk area.

Solar power stations

To date, this is one of the most expensiveways to generate electricity. The main reason is the high cost of solar batteries, to reduce the cost of their production with simultaneous increase in efficiency and lifetime is not yet possible. If this goal is achieved, getting electricity with solar panels will become one of the most convenient and cheap options. Thus, the cheapest electricity is provided by hydroelectric power stations and nuclear power plants, the next step is occupied by thermal power plants. Unfortunately, there is no real alternative for them yet.
