"How to save 5 thousand rubles?"

Energy-saving lamps

Replacing incandescent bulbs with modern energy-saving bulbs can, on average, cut your home's electricity consumption in half. The energy-saving lamp lasts 10 thousand hours. while an incandescent lamp takes an average of 1.5 thousand hours, that is, 6 - 7 times less.
An 11 W compact fluorescent lamp replaces a 60 W incandescent lamp. The costs are recouped in less than a year, and it lasts three to four years. Calculated: replacing in an apartment with an area of ​​45 - 50 sq. meters of lamps with conventional lamps for fluorescent, you can save about 1500 kWh per year. It is more advisable to use compact fluorescent lamps in the corridor and in the kitchen, where the light burns longer. If you are not used to turning off the lights after you, then this is the most acceptable way to save both electricity and money.

Savings: up to 1000 rubles.

Use voltage stabilizers. Power engineers advise using voltage stabilizers! By connecting a computer or TV through the stabilizer, you can achieve a significant reduction in power consumption.
The "sleeping" state is deceptive
Anyone who thinks that household electrical appliances that are not working, but connected to the mains do not consume electricity and do not affect the amount of electricity bills, they are mistaken. Electricity is consumed in such a "sleeping" or standby state when only the "red eye" on the panel of the household electrical appliance is turned on. So how much electricity is consumed by non-working TVs, video and stereos that are connected to the network, microwaves?
Studies have proven that the consumption of electricity for devices in a standby state is about 10% of the total electricity consumption! So, on average, the TV works about 4 hours a day. The rest of the time "at idle", being simply connected to the network, it consumes about 1.1 kW / h of electricity per day, per month - 33 kW / h. Microwave

The oven, the video recorder "eat" 0.4 kW / h per day, 12 kW / h - per month. And one hour of idle operation of the electric heater will ruin 1.4 kW / h per day or 42 kW / h per month.

Savings: up to 300 rubles.

How much does the refrigerator "eat"?

The refrigerator is one of the most energy-consuming appliances. It is constantly connected to the network and consumes as much electricity as an electric stove. A tidy figure comes up per year: compressor refrigerator - 350 - 550 kW / h, absorption refrigerator - 600 - 1600 kW / h.
The economy of the refrigerator, first of all, depends on the mode of its operation, associated with the frequency of use, and compliance with the rules of operation. At correct operation refrigerator energy consumption is reduced by 15 - 20%.
After opening the refrigerator door three times, the electricity consumption increases by 1%!

Savings: up to 300 rubles.

If you want to be richer - know how to save
Do not use the hob without a “good reason”. After all, everyone knows: to drink tea, for example, it is better to use a less energy-consuming device - an electric kettle. Thus, you can save up to 250 kWh per year.
Monitor the health of the stove. Using faulty burners leads to an overconsumption of electricity by 3 - 5%.
What kind of utensils you use plays a big role. You can save energy by using special cookware with a thicker bottom equal to or slightly larger than the diameter of the burner. Energy saving when using such cookware is from 140 to 280 kWh per year.
Using crockery with a curved bottom can result in an overconsumption of electricity up to 400 kWh per year.
By the way, an important fact. If you cook food in a bowl without a lid, you will consume three times more energy!
Electrical appliances consume 48% of the electricity consumed, lighting 12%, and cooking 40%. The annual electricity consumption of a family with an electric stove is 3500 - 4000 kW / h.

Savings: up to 400 rubles.

Which irons are economical? Use the temperature regulator to iron a particular type of fabric. Why heat your iron to its maximum temperature and then wait for the iron to cool down to iron the synthetic fabric? You are wasting both time and energy.
Buy irons with stepless steam control, depending on the type of fabric. If you need to steam hard-to-iron fabric, for example, jeans, you can use the enhanced steam mode. The "LOW PRESS" mode allows you to steam delicate synthetic fabrics by supplying steam when working at low temperatures.
If you still use an iron without a temperature regulator, it's time to think about purchasing a more modern one, in which the heating time is reduced from 15 - 20 minutes to 6 - 7 minutes, energy consumption is reduced by more than 20%.

Savings: up to 500 rubles.

Load the vending machine completely
From the point of view of electricity consumption, the most economical automatic washing machines... The main rule of thumb for economy is full load. Do not start washing until you have accumulated enough laundry to fully load the machine!
Try to wash at a lower temperature. At a washing temperature of +90 "C, electricity consumption is 30 - 40% higher than at a washing temperature of +60" C.
Use energy saving programs: by lengthening the wash duration, you can lower the water temperature. In this case, the energy savings will be 45%, because the main electricity consumption goes to heating water.
By hand washing particularly dirty stains and soaking dirty laundry, you can avoid the need for washing at high temperatures and high energy consumption.

Savings: up to 900 rubles.

Insulate your apartments well
Heat energy losses heating system in residential buildings account for almost 20%! Most of the heat loss occurs:
- due to non-insulated windows and doors - 63%;
- through window panes - 15%;
- through ceilings and walls -15%.
Many, instead of home insulation, use electric heating devices in addition to the heating system, which leads to increased electricity consumption. Northerners, like no one know: insulation is the best energy saving.

Savings: up to 600 rubles.

Saving energy when consuming water
Did you know that up to 2,000 liters of water per year flow out of the faucet from which water drips (10 drops per minute).
And if each of the four members of your family leaves the water tap open for only 5 minutes a day, you lose 7 kWh of energy, throwing 1000 rubles out the window?
Taking a shower is much cheaper than taking a bath. Taking a bath (140-180 l), you expend three times more energy than taking 5 minutes. shower.
Sprayers on taps allow for more efficient use of water.

Savings: up to 1000 rubles.

And:
- insulate windows and doors to prevent heat loss!
- do not obstruct the heating radiators with furniture and curtains!
- turn off the light when you leave the room!
- install counters cold and hot water!
- use a table lamp when there is no need for general lighting rooms!
- when cooking on the electric stove, turn it off a few minutes before the food is ready!
- Cover the pan with a lid when cooking!
- install two-tariff electricity meters!

Following the tips on energy saving, you can put in the family budget from 3000 to 5000 rubles a year, which is 25% of the family's energy consumption expenses.

Today every family knows - savings are important, savings are needed!

Operating procedureintelligent energy savingaccounting systemenergy resources.
Data from the pulse outputs of cold and hot water meters are fed to the input of the BSI-01 counter-output-radio interface converter, which counts the number of pulses and transmits this data via the Mi-Wi wireless network to the apartment block, which calculates the current value of the flow rate of cold and hot water with saving the result in non-volatile memory. Then the apartment block broadcasts them via Enternet to the district energy supply metering and dispatching server. Converter "counting output-radio interface" BSI-01 is battery powered.

Apartment block with top cover removed and apartment control panel (right)

At the same time, taking into account the water consumption, the temperature of the hot water pipeline is continuously monitored using a wireless temperature sensor installed on it. Temperature measurement is carried out after a specified time (20 ... 30 seconds) after the start of the current flow cycle and, when the temperature exceeds the standard parameters, information about this fact is transmitted to the apartment block with data relaying to the regional energy consumption server. This is necessary for the implementation of the legal rights of users to reduce costs in case of abnormal power supply.
When the wireless sensor of water leakage BDUV-01 is triggered, information about this is transmitted to the apartment block. Based on the given algorithm, the apartment block makes a decision on the dispatch (cut off the supply) of cold and hot water, which is indicated by a corresponding indication on the apartment panel. The command to shut off the water is sent wirelessly to the valve control module MUV-01 and is relayed by it to the executive device - a ball valve. After executing the command, a confirmation receipt for the apartment block is issued. In addition to what has been described, forced shutdown of cold and hot water from the regional server for accounting for dispatching of energy resources in the absence of payment, the need for strict limitation of consumption, etc., as well as dispatching of water by user commands, can be used.
The procedure for metering and dispatching electricity is similar to the procedure for metering and dispatching water supply.
Accounting and regulation of heat supply is carried out as follows. Data on the temperature of the heating radiator and the temperature in the heated room are transmitted to the apartment block at a predetermined frequency (100 ... 300 seconds). When a manual thermostatic valve is used, the specified data are accumulated in the non-volatile memory and, after averaging with a cycle of 3 ... 5 minutes, are sent to the regional energy consumption server. When using automatic electronic temperature control using special software of the apartment block, a loop for automatic maintenance of a given temperature is implemented based on a modified proportional control with the generation of electric valve control commands. As the initial data for regulation, daily and weekly regulation programs (profiles) are used, set by the user through the apartment panel or the WEB-interface via the network. Simultaneously, taking into account the data on the room temperature and the temperature of the heating radiators, the state of the batteries of all battery-powered wireless devices is monitored. The calculation of the consumed heat energy by each individual consumer is carried out using special software of the regional energy consumption server based on the proportional principle according to the data on the recorded temperatures, heat transfer from installed radiators and data on the promised house consumption.

On the regional server for metering and dispatching energy consumption, data received via the Internet from apartment blocks are archived for later use. The server is turned on around the clock, has the necessary data backup facilities and is located in a specially designated room. Remote client workstations are connected to the server with special software for employees of government bodies, energy supply organizations, management companies, homeowners' associations and billing systems. The client software has a user-friendly user-friendly interface that allows you to observe (graphics, tables), statistically process and analyze energy consumption information.
The client software makes it possible to block consumers. In this case, after the operator has given the blocking command, it is sent from the client workstation to the energy consumption server, then to the apartment block. From the apartment block, the command is retransmitted to the corresponding module, which includes the dispatching actuator.

Connection and configurationintelligent energy savingaccounting systemenergy resources.
The power supply of the valve control module MUV-01 is carried out from power supplies (hereinafter referred to as the power supply) with a nominal voltage of 12 V. Voltage deviations should be in the range from minus 15% to plus 10% of the nominal value. The power supply for the device must be rated for a maximum current of 1 A.

Rice. 2 - MUN-01 connection diagram

Ball valves are connected to the MUN-01 board to the relay outputs.

The connection of the meter pulse output (water, electricity, etc.) to the BSI-01 board is carried out to the terminals of the counting input, while one output of the meter's pulse output is connected to the general output of the board ("minus" of the power supply), and the other to the terminal channel inlet (see Fig. 3).

Rice. 3 - Connection diagram of the BSI-01 device

The BSI-01 and MUN-01 boards are powered from a + 3V lithium battery power supply, however, it is also possible to connect an external source with a + 3 ... 5V voltage.

The power supply of the apartment block, which includes the network hub card (Fig. 4), is carried out from power supplies with a nominal voltage of 12 V. The voltage deviation should be within the range from minus 15% to plus 10% of the nominal value. The power supply for the device must be rated for a maximum current of up to 1 A.

Rice. 4 - Wireless network module of the apartment block

Setting the parameters of an intelligent energy-saving energy accounting system can be carried out both from the server and through access using the "Telnet" terminal.
Algorithm for commissioning a new device (wireless module):

• The operator sends a command to the selected apartment block to search for a new wireless device. After that, the wireless network goes into the standby mode for connecting the device with the factory address (by default, which is equal to 255).
• The operator presses and holds for 3 ... 5 seconds a special button on the device (wireless module) added to the network, after which the device establishes communication with the network node (apartment block). In this case, if the device is within the range of several wireless networks (neighboring apartment blocks) at the same time, then it will only connect to the network that was previously switched to the standby state (see paragraph 1).
• The connected device sends its factory settings (type of module, type of sensors, values ​​of scale factors for converting the readings of the sensor (meter) into the value of a specific physical quantity, etc.) to the apartment block, which then transmits the received settings to the server, which in turn - into a special utility-client program for system administration. After that, the operator is shown a form (Fig. 2.) for configuring the device with the fields already filled in, based on the received factory settings.
• The operator, if necessary, corrects some fields (device address, its name, etc.) in the specified form of settings and presses the "Apply" button. The entered settings are sent to the server, then through the apartment block (local repeater) to the added device, where it is stored in non-volatile memory.
• After the performed actions, the device turns out to be connected to the wireless network and for confirmation sends back to the Server the newly received new settings.

Before the first connection of the local repeater (RL-01) to the LAN-Ethernet network, it is necessary that the system administrator serving this network assigns an IP address and a subnet mask for the connected device, as for a network device (see Table 1 for factory settings) ), and also provided access to the data collection server TCP port 2021.

To enter each of these pages (except for "Technical support"), you need to enter your username / password (by default Admin / start) in the authorization form (Fig. 6).

On the page of the WEB-interface "Devices", the user can view the list of all devices connected to the apartment block, as well as the values ​​of the current readings for the selected metering module (Fig. 7).
The status of the device in the radio network (connected / disconnected) and the time of its last activity are also displayed. This allows you to quickly and visually assess the operation of the system (the quality of communication with devices, the rate of data exchange, etc.).
For each of the values ​​coming from the devices, the measurement time is displayed, which allows you to have a clear idea of ​​the relevance of the data at any time.
When developing the WEB-interface, the technology was used AJAX, Ajax (from the English. AsynchronousJavascriptandXML- "Asynchronous JavaScript and XML") - an approach to building interactive user interfaces of web applications, which consists in the "background" exchange of data between the browser and the web server. As a result, when data is refreshed, the web page does not completely reload, and web applications become faster and more convenient. This allows the user to observe the changes in parameters in real time without having to press the "Refresh" button of the browser all the time.

Any modern industrial enterprise consumes a significant amount of energy resources in various forms. Including to ensure their life and technological processes enterprises of various industries consume electricity and pipe energy resources (heating, hot water supply, etc.). The cost of purchasing energy resources is a significant share of the cost finished products, which determines the relevance of energy saving. In turn, energy saving is impossible without accurate accounting. Therefore, the first step to reduce costs will be the introduction of an integrated energy accounting system.

What is integrated energy accounting?

Comprehensive accounting of energy resources provides for the construction of a single automated system, which collects readings from all primary metering devices that measure the consumption of electricity and other resources. Information from metering devices goes to the data collection device and is transmitted to the server, where they are then processed. As a result, the company receives a detailed picture of energy consumption and a significant amount of analytical information required to optimize consumption.

Benefits of integrated energy metering

The introduction of an integrated energy accounting system has a number of advantages over the use of separate systems for each specific type of resource. First of all, it is a more economical solution due to the use of a single infrastructure for collecting data from metering devices of different resources.

In addition, the integrated system provides the following operational benefits:

• High information content. The system of integrated accounting of energy resources provides the ability to obtain data on consumption at any of the entities or structural units enterprises. It also provides the ability to control the readings of energy meters of various kinds(electricity, gas, heating, water, etc.).
• Relevance. Complex system allows you to control energy consumption in real time. It also provides the accumulation of information over the past periods for subsequent study and analysis.
• Full automation of the information collection process, which has great importance for enterprises with a complex structure and a large number of energy consumption meters.
• High level of accuracy of the received information on consumption.

Thanks to these advantages, complex energy metering is more convenient to use. In addition, the system allows for truly efficient control of energy consumption, which makes it possible to identify problem areas and find new opportunities to save resources.
