Benefits for energy-efficient equipment (Zubkov S.). Energy efficiency of equipment Energy efficiency of switchboard equipment

Energy efficiency of equipment implies the use in production and in everyday life of devices that consume less energy resources to achieve performance indicators or even improve them compared to conventional equipment.

Increasing the energy efficiency of equipment in enterprises is an important and economically feasible, but so far little-used way to increase the profits and competitiveness of an enterprise. It can be confidently stated that increasing the energy efficiency of equipment will allow industries to more successfully overcome dependence on energy resources, not be afraid of unreliable energy supplies, compensate for rising prices and increased energy bills, and also reduce damage to the environment and health.

Why does the introduction of technologies that increase the energy efficiency of equipment obvious benefits Is it quite slow? There are several reasons for this. First of all, conservatism. It takes some time before something new becomes fashionable and then habitual and obligatory. Another reason is the lack of awareness of the population in the field of energy efficiency of equipment. For example, unsubstantiated claims of harm fluorescent lamps force consumers to avoid purchasing them, although objectively there are no reasons for this. The next factor is price. It is of great importance, because, at first glance, the costs of new equipment are prohibitively high. But an economic calculation of investments in improving the energy efficiency of equipment has shown that the payback period, depending on the type of project, ranges from six months to six years, and this is a very good indicator when compared with investments in traditional enterprises. And this is completely natural, since with a constant increase in energy prices, thanks to the high energy efficiency of equipment, the period of financial return becomes shorter.

According to expert calculations, it turns out that increasing the energy efficiency of equipment in Russia by just 1% will ensure a significant increase in GDP. This can be explained, among other things, by the fact that the required costs for measures to improve the energy efficiency of equipment in the fuel and energy sector, in industry and public utilities two times lower compared to capital investments in the construction of new capacities with traditional technologies. And if we take into account the amount of resources in the form of oil, coal and gas that will be required for an equivalent increase, the conclusion suggests itself: increased energy efficiency of equipment is the additional power needed by our growing economy. Power that will allow, while maintaining production volumes, due to rational use and savings to transfer the “extra” energy to another consumer.

Increasing the energy efficiency of equipment is not advertising slogans or dubious demands of environmentalists, but a commercial means that allows you to increase profitability and strengthen your financial position. In general, increasing the energy efficiency of enterprise equipment leads to:

 reducing energy costs;
 increasing the profitability of enterprises;
 increasing the quality of manufactured products;
 formation of a positive image of the company;
 increasing the competitiveness and capitalization of the company.

For every enterprise, settlement, and even for each building in the future, a program should be developed to increase the energy efficiency of equipment. And its step-by-step implementation will lead to rapid economic growth in our country, increased labor productivity and improved environmental conditions.

You need to save money not when purchasing engineering equipment, but when using it. Energy-saving systems, as a rule, are significantly more expensive, but over time they will definitely pay for themselves, and then again. long years ensure conservation of resources and your funds.

How bigger house(or office), the higher the cost of maintaining it. That is why it is so important, when installing engineering systems, to pay attention not only to the quality and manufacturer, but also to the level of energy efficiency of the equipment.

European countries have been most successful in this (due to the high cost of utility bills). It is in Europe that passive houses have become widespread and are being actively implemented. energy efficient technologies.

Gradually, the topic of energy saving is becoming more and more popular in Russia. What equipment that reduces energy costs is on our market?

Even more energy efficient - ventilation units with air heat pumps , capable of not only providing air exchange, but also cooling or partially heating the air in the room.

Recently on sale mini heat pumps - duct heat exchangers with connection to a geothermal circuit for preheating or cooling supply air in the ventilation system.

The use of heat pumps in ventilation systems makes it possible to provide air conditioning at home with minimal energy consumption. But even among traditional air conditioners there are devices that allow you to save energy - these are inverter split systems . They have a compressor that changes the engine speed, and therefore the cooling power. Thanks to this technology, air conditioners not only more accurately maintain the set air temperature, but also reduce electricity consumption by an average of 30% compared to other models.

Energy saving heating:

Geothermal heat pumps They also allow you to spend a minimum of energy when heating your home. They provide optimal temperature indoor air, are used to provide hot water supply in the water supply system. However for climatic conditions In the Ural region, the use of such devices as the only source of heating is not always justified. Heat pumps are usually installed together with boilers.

Among gas boilers, they have high energy-saving properties condensing boilers . And among solid fuels - pyrolysis. Thanks to the special method of fuel combustion in such boilers, efficiency increases several times, and energy consumption is reduced.

If temporary heating is required, for example, in the off-season, then it is better to choose electric convectors , and those that can automatically turn off when the desired temperature is reached.

At the same time, LEDs have their drawbacks, for example, they are very difficult to dim. Therefore, in some cases it is worth using energy-saving fluorescent lamps.

Alternative energy sources:

In addition to the heat pumps that we talked about above, there are others: wind generators, solar panels.
Alternative energy can be used for heating a home, heating water, lighting, etc.

However, for the Urals the use of wind generators and solar panels justified only when used in conjunction with other equipment.

Automation systems as an energy saving tool:

Smart House allows you to reduce costs for heating, ventilation, air conditioning, lighting, and other life support and comfort subsystems, even if engineering equipment does not have high energy-saving properties.

Specialists of the Terkont group of companies are ready to offer the most modern, high-quality, energy-saving equipment that provides minimum costs for the maintenance of a home or office. Order design and installation engineering systems"turnkey" is possible in our sales offices in Yekaterinburg or Chelyabinsk.

In Russian conditions, to achieve implementation only energy efficient equipment not easy, since a private user cannot always save resources; this is not in his power. You can talk about saving resources with the owner of a private house, but only if the organization serving the village behaves correctly and decently.

If the costs of various energy losses in village networks are large, then the savings of an individual user may be too insignificant. Much higher value will buy in this case organizational problems network maintenance, problems of old networks and other similar insoluble utility issues. In new urban-type settlements there are usually fewer utility problems; owners of private houses can be more free in choosing equipment. No one is more interested in the energy efficiency of their home than a private owner. The quality of the equipment and its service life is also a private choice, so a private owner can save energy resources without fear that all his savings may be negated by the need to replace a bad meter or a low-quality pump that the service organization installed.

The use of only high-quality and most durable energy-efficient equipment, it seems, should not raise any questions. However, such energy efficiency issues arise in places where there are plenty of other resource-saving opportunities. First of all, it is necessary to eliminate all losses due to normal aging of equipment. New homes do not have this problem, but not everyone can use the most energy-efficient equipment, since it costs more. The question arises of the return on investment in energy-efficient equipment. In some cases, houses are built for sale, so the most expensive and energy-efficient equipment is not always installed in them. On the contrary, they are looking for a way to supply the oldest and cheapest equipment that is supplied from abroad. Therefore, the number of people who can fully benefit technical progress, not that big. These are people who are building a “house for themselves” and want to operate it as cheaply as possible. To do this, they need to supply the most expensive and energy-efficient equipment and incur the highest one-time costs. The issue of choosing equipment and its necessary and sufficient functionality is very important here. Quality is very important construction work, quality and execution of engineering projects.

When choosing an energy efficient gas condensing boiler It is important to understand that all other possibilities for saving resources have been exhausted. There are savings opportunities that most people don't even realize about. For example, the work optimization method may not be exhausted heating system due to uniform heat distribution. This situation, in which the heating system operates extremely unevenly, occurs quite often. In this case, even with thermostats, it is impossible to achieve the desired temperature in the premises of the house. To correct this situation, it is necessary to set balancing valves. The valve regulates the volume of coolant that passes through each heating circuit or through each heating device. Direct resource savings when installing valves are up to 40%, while the use of a condensing gas boiler cannot provide savings of more than 35%. The procedure for setting up a heating system does not cost more than 1% of the total cost of the entire heating system at home.

Savings on balancing the system do not end there. The fact is that when balancing the system, everything heating equipment(boiler, radiators and pipes with fittings) operate in better conditions, which affects their durability. However, it is necessary to strive to optimize costs and use the most modern equipment; this quickly pays off. "Smart", intelligent heating properties gas boiler allow you to adjust the gas flow in direct proportion to the heat demand. The boiler automation (AUTO function) maintains the water temperature in the heating circuit. The INFO TOP function makes it possible to control the operation of the boiler and its modes. The display shows all values ​​on the screen. COMFORT function reduces waiting time for arrival hot water into the faucet mixer. Water arrives in 5 seconds. A private homeowner can achieve such operating conditions for the equipment so that not a single calorie of heat is wasted. The use of battery thermostats can save 20% of energy resources in the heating system.

Savings occur due to the fact that individual temperatures are set in each room. There is no longer any need to open and close the windows to regulate the temperature in the rooms. Modern thermostats can set the temperature in the range of 6-26 degrees. For example, you can lower the temperature in rooms that are not in use or turn off the heating at night. Energy savings can be achieved through the use of energy-efficient pumps that operate in heating systems. Energy-efficient pumps save about 30% of all the electricity that goes into maintaining the operation of the pumps in the system individual heating Houses.

In this article we will get acquainted with technical devices that save energy, heat and water in rooms. By installing this equipment in educational institutions, you will find solutions to energy efficiency problems. Simple, like the school “twice two.” But they are a guarantee of savings.

5 types of energy saving equipment

Before we talk about these important energy-saving devices, a few words about meters. After all, they can rightfully be considered one of the specific measures to increase energy efficiency. Educational institutions will benefit a lot if they put savings on water, electricity, heat and gas on the meter. With their help, unnecessary energy resources are not consumed, and you will have to pay less for what you use. Each counter is beneficial from a savings point of view - communal payments are reduced by at least three times. And that's without taking into account that important fact that any meter installed in an educational institution pays for itself quite quickly.

Window. We insulate and install double-glazed windows

Energy-saving glass is the first and, perhaps, main protection against heat loss. A special thin coating on the glass allows visible light to pass through and retains thermal radiation. Energy-saving double-glazed windows have many undeniable advantages:

• single-chamber double-glazed windows with energy saving glass compared to usual double-glazed windows demonstrate better thermal insulation;
• provide a comfortable microclimate, create convenient working conditions (maintain a temperature of +20°C in the room at -20°C outside the window).

Radiators. Setting up heat supply and keeping warm

Heating equipment also contributes to energy saving. The newest in this regard are considered bimetallic radiators, which effectively replace old cast iron batteries, not amenable to cleaning. Such radiators are durable and sealed. Strengths of such heaters are obvious:

• they combine the advantages of steel and aluminum radiators;
• have high energy efficiency in heat transfer;
• thanks to the properties of aluminum, the radiator heats the air in the room 5 times faster than conventional batteries;
• Their installation is beneficial at least because the radiators are guaranteed for 15 years.

We saved energy, but how to increase it? When the temperature outside is below -20C, you cannot do without electric radiators. Here are their convincing advantages:

• independence from central heating and autonomy;
• automatic or manual control room temperature;
• strength, mobility, reliability and safety in operation.

Lamps. We give the room natural light and people health

Replacing incandescent lamps with fluorescent and LED lamps lighting on average saves about 5 thousand dollars per year for a regular high school. In addition to such significant energy saving indicators, another important factor is the latest equipment. Modern lighting devices protect our health.

Engineering solutions for new lighting equipment are simple and do not require high costs, they quickly pay for themselves thanks to a reduction in energy consumption by 30-80%.

Let us dwell in more detail on the properties and advantages of energy-saving lighting equipment - in particular, fluorescent lamps:

• allow for excellent light output and color rendition, which is important for indoor work;
• provide soft light;
• consume little energy (85% less than outdated lamps), while having a long service life.

However, after such a lamp burns out, under no circumstances should it be broken or thrown away. A huge disadvantage of fluorescent lamps is their additional disposal after the end of their service life, because... they contain mercury.

LED lighting is the most promising light source in this moment, largely due to its energy efficiency and other strengths:

• LEDs are economical - they run on low voltage and do not require large amounts of energy (up to 75% savings);
• have an almost eternal service life - up to 100,000 hours of burning (when working 8 hours a day, the lamp will last 35 years)!
• durable and less susceptible to mechanical stress, because they do not contain spirals or electrodes that can be damaged;
• are different in shades of color, shape and power, which certainly expands the possibilities of their use.

Relay. Adjusting the voltage

The use of a whole army of electrical appliances in educational institutions leads to network overloads, which can cause short circuits. Electrical wiring installation standards have long been outdated, and the time has come to install a modern protective equipment. The solution is simple - the electrical distribution networks are being reconstructed and their capacity is being increased.

Modern relays save energy by allowing you to use multiple electrical appliances without creating loads. The operating principle of such a relay is simple. When the total power of electrical appliances in use exceeds the standard, one or more non-priority appliances are turned off. For example, if it is important to use sockets to power computers, then other devices will automatically be disconnected and connected. At the same time, we will not feel any discomfort and will insure the network from loads.

Faucets. Save water

Energy saving includes not only the conservation of heat, but also water, because a lot of electricity is spent on its delivery. A faucet with a photocell is the best thing people have come up with to save water to date. Using a touchless faucet uses 6 times less water compared to a traditional tap. It does not have a valve, but the mixer works regardless of this when you bring your hands to it. The source is “hidden” in the case infrared radiation and a photocell that receives the beam. We bring our hands to the tap, and they fall into the field of view of the photocell. That's why electronic device instantly “reacts” and turns on the water. Economical, convenient and hygienic.

Climate control systems of buildings consume a significant amount of energy resources, which ultimately affects operating costs, many different energy-saving schemes have been developed to reduce these costs. Often the main way to save is to combine systems, excess heat from one system is transferred to another, or equipment is initially designed with low energy consumption or using renewable resources, or resources of lower cost.

Main types of energy saving equipment

Equipment with low energy consumption

Almost everything can be included in this category. modern equipment, because technologies are developing, and the energy efficiency class is regularly being raised, so simply replacing existing equipment with newer and more economical ones is already one of the ways to save energy.

Energy-saving equipment using green energy sources

This type of equipment includes solar, wind and earth energy, in the context of our systems this is the use of solar collectors for hot water supply and heating systems, as well as the use of geothermal heat pumps with ground collectors. Such equipment, of course, consumes not only green energy, but also electricity, but it is used mainly for energy transfer, and not for creation. For example, in solar collectors electricity is needed only to operate the pumps and automation system. In the case of a heat pump, electricity is also spent on heat generation, or, more precisely, on conversion, but it is used much more efficiently, and if you use a ground collector for cooling, you can really only get by with electricity to operate the pump to pump water. Our sewerage system design company, ventilation, heating and other engineering systems, thanks to a variety of designed and installed projects, has accumulated significant experience in the use of combinations of various resources and equipment for all building engineering systems.

Energy-saving equipment using cheaper resources

This type of equipment can include solid fuel boilers, since it is cheaper than gas, or the use of heat pumps and even the use of electricity as the main source of heat, while the electric boiler operates at night at a cheap rate and heats the storage tank, which is consumed during days when the electricity tariff is higher.

Equipment for energy saving in heating

You can save money in heating systems by using and combining various sources heat pumps, such as a heat pump, solid fuel boiler and even solar collectors. The essence of the systems is that the equipment has its limitations, and when, for example, for the operation of an air heat pump it was too cold to turn on another system. In case of solid fuel boiler, whose power control system is not very flexible, you can use a storage tank to accumulate excess heat during combustion and use it the rest of the time, and in case you forgot to add fuel, there is always a gas or other boiler in reserve. The greatest efficiency can be achieved in the heating segment of private residential buildings and cottages. By combining heat sources and using energy prices, you can achieve significant savings; you can do this manually, or you can rely on automation systems; a number of different weather-dependent controllers have been specially developed for this. Controller sensors are installed in the return pipeline, in the supply pipeline, outdoors, indoors, and a control signal is also supplied to the three-way control valve of the system and to the boilers. Receiving information from all sensors and sending regulatory signals to the actuators, the controller controls the operation of the system according to configured algorithms.

Equipment for energy saving in air conditioning

There are not many energy-saving technologies that can be used in air conditioning systems; the most efficient systems are ground collectors, but they are mainly suitable only for small buildings with the availability of land for the device. Thus, the most efficient systems can be used mainly in the niche of cottages and private country houses. But not everything is so bad; you can save money on air conditioning by using intelligent systems, in particular, multi-zone systems are the most efficient, thanks to a large power control range, weekly programs and effective system regulation of this type allow significant energy savings. In energy saving systems, it is also possible to use the condensation heat of outdoor units technical refrigeration equipment and use it to heat water DHW systems or other production needs.

Equipment for energy saving in ventilation systems

Heating and cooling air consumes a lot of resources and throws it away exhaust systems outside is not very effective, so air heat exchangers - recuperators - were developed for ventilation. Efficiency supply and exhaust systems with a recuperator it can reach 75%, depending on the type of recuperator. The essence of the work is to heat and cool the supply air supplied to the room due to the exhaust air removed. Using frequency controllers and various sensors can also reduce energy costs by reducing air volume during non-operating or part-load operating hours.
