Thermal exhaustion of the battery. Razrahunok pressure of one section of a steel radiator

The problem of scorching in our latitudes is significantly worse, lower, for example, in Europe, with a mild climate warm winters. In Russia, a significant part of the territory is under the rule of winter until 9 months of rock. It is also important to add enough respect to the choice of scorching systems, zocrema, rozrahunka tension of scorching radiators.

On the vіdmіnu vіd, de vrakhovuєtsya less than the area, rozrahunok natuzhnostі radiatorіv scorched to see through for іnshoy scheme. In this case, it is necessary to protect the height of the beds as well, so that it is a big deal, in which it is planned to install or replace the scorching system. However, do not be afraid of warto, even if in the final bag the whole rozrahunok will be based on elementary formulas, it doesn’t matter to cope with them. Radiators heat up the air intake of convection, so that circulation is repeated in the room. Heat up again, go uphill and get colder. So, in this article, you take into account that it is not the simplest case of sweating of the radiators of scorching

For example, take an area of ​​15 square meters and with stele 3 meters high. In such a rank, about to repeat, what can we heat up our future scorching system we become:

V=15x3=45 cubic meters

Dali vvazhaemo tension, as it will be necessary for heating the appointment of a given obligation. Our drop has 45 cubic meters. For which it is necessary to multiply the volume of application by the intensity required for heating a cubic meter of air in this region. For Asia, Caucasus CE 45W, for middle smuga 50 W, close to 60 W for a night out. As a butt, we take the intensity of 45W and the same is taken:

45 × 45 = 2025 Tue - the intensity is required for heating a room with a cubic capacity of 45 meters

Selector of the radiator

Steel radiators

We'll keep fighting for the temples different types scorching radiators and there are only significant nuances, about which it is necessary to find out when choosing a radiator for your scorching system.

In times of rozirakhunku tightness of steel radiators, singed, everything is simple. Є necessary tension for already existing accommodation - 2025 Tue. At such a time, we marvel at the tables and look at steel batteries, that we see the necessary amount of watts. It is not easy to find such tables on the websites of distributors and sellers of similar products.

Axis butt of this table:

The tables indicate the type of radiator, for which stock we take type 22, as one of the most popular and most suitable for its calm capacities. And it’s a miracle for us to have a radiator with a size of 600 × 1400. Heat sink pressure becomes 2015 Tue. Ale better take more trochs, lower less for exhaustion

Aluminum and bimetal radiators

At the same time, one important thing is to note the risk of swelling of the radiators. Aluminum bimetallic radiators most often sold in sections. І tightness in tables and catalogs is indicated for one section. To do this, it is necessary to divide the tension, it is necessary for heating a given application to heat one section of such a radiator, for example:

2025/150 = 14 (rounded to the nearest digit)

I took away the necessary number of sections of such a radiator to accommodate a volume of 45 cubic meters.

Don't overdo it!

Also note that 14-15 sections for one radiator is the maximum. Installing radiators of 20 and more sections is not effective. In such a situation, the number of sections should be divided and 2 radiators of 10 sections should be installed. For example, put one radiator near the window, and the other one at the entrance to the room, or on the opposite wall. Zagalom, on your thought.

With steel radiators, that is the story itself. If the room is too big to finish and the radiator to go out too big - rather put two smaller ones, ale total tightness.

If in a room of the same volume 2 weeks or more, a good solution would be to install a radiator under the skin of the windows. It’s easy to finish everything with the help of sectional radiators.

14/2=7 sections under the skin window for the room of the same volume

Ale, shards of similar radiators sound are sold in 10 sections, rather take a guy a number, for example 8. We will not order a stock in 1 section in severe frosts. The pressure will not change especially, but the heat inertia of the radiators will change. It may be darker, as cold weather often penetrates into the room. For example, as an office location, as often as clients visit. In such weathers, the radiators heat up three times more quickly.

What is the work of the rozrakhunkiv?

In case of rozrahunku natuzhnosti radiatorіv scorched all kіmnat it will be necessary to choose piping by diameter, faucets. The number of radiators, the length of pipes, the number of taps for radiators. Check the volume of the system and choose a suitable boiler for it.

For people, houses are often associated with warmth and calm. I want to keep the houses warm, it is necessary to add proper respect to the system of burning. Today's vineyards vicorist new technologies for various elements of scorching systems. However, without a competent planning of such a system, these technologies can be similar for the same applications.

The replacement of one opalizing attachment will be costed by fakhivtsy from 2000 rubles. Accurate varity stale in the context of folding and obyagu addendum robots so stinks will be necessary.

In this article, we can look at the butt of the selection and the new complete set of steel radiators of KERMI scorching.

To simplify the procedure for selecting batteries for burning, we divide them into two main groups:

1. LOWER connection(FKV);
2. Beach connections(FKO).

Retail in these groups, the connection is singed in the supply of pipes, which strongly influences them old look, On the presence of a radiator with a regular connection to a built-in temperature controller, and it is very important to indicate the battery variability.

Since you have chosen a radiator for the type of connection, you need to choose the length and height of the ceramic battery. As a rule, kermi radiators are installed every night - this creates an additional lull at the booth (alternatively, for the consumption of KERMI, radiators can be installed on another wall).

Therefore, we robimo rozrahunok radiators singed for a long time for the entire pіdvіkonnya, and according to the height, the kermі radiator is responsible for stepping on a distance of 10 - 13 cm from the finished pіdlogs and floorings and from the pіdvіkonnya!

Now the most convenient choice is now - the same type of radiator chi yogo glibin. This characteristic is already strongly influenced by the heat output of the scorching radiator, and if it is wrong to take this value, then you will either waste your pennies, or, more, you will be cold in the scorching season, Because the pressure of the radiator is not suitable for heating the room.

If you are confident in your abilities, you can independently choose kermi radiators for your booth best prices scorched on the radiator, so you can always buy cost-free radiators from our store (For your consideration, please send this product to our store).

Since we have chosen the standard sizes, it is clear that it is necessary for the installation. AT standard kit KERMI connection is already transferred to the wall mount, Mayevsky valve (ventilator), plugs (with a remote connection). So for the connection of the radiator, the scorched virobnik is amusingly still pressing on the kit.

For the installation of scorching batteries on the sub-log, you will need to add additional batteries.

When installing scorching batteries, it is necessary to connect the scorching battery to the scorching system behind the auxiliary shut-off valves. You also need to be aware of how the trumpets of scorching to the batteries will come (in the middle of the walls or the bells). For this, there are two options for fittings: bichna (if the pipes are installed at the wall) and straight (if the pipes are laid, the walls are laid). For added aesthetic aesthetics, nickel-plated copper tubes can be fixed during installation of scorched radiators.

Rozrahunok radiators scorched

Rozrahunok radiators scorched by me zrobil themselves.

Formula with area adjustment

The formula for the rozrahunka of the tension of the steel annex is scorched from the irradiated area: P \u003d V x 40 + heat loss through windows + heat loss through outside doors P - tightness; V - general application; 40 W - heat intensity for heating 1m3; spend heat through the windows - the increase in the value of 100 W (0.1 kW) for 1 window; spend heat through the outer doors - rozrahunok zі value 150-200 watts.

Butt: The room is 3x5 meters, with a height of 2.7 meters, with one window and one door. P \u003d (3 x 5 x 2.7) x40 + 100 + 150 \u003d 1870 W You can find out for the help of these rozrahunkivs, as if there will be a heat supply for the scorching building.ensuring sufficient heating of a given area.

Important! Like a room, it is roztashovana on the rose ends of the bud, it is necessary to rozrahunkiv the exhaustion of the batteryadd 20% to the stock. Styles are necessary to add at different parts of the reduction heat transfer temperature. As a living accommodation in areas with severe frosts and bitter winters, it is necessary to subtract the numbers by 1.2 - the coefficient of heat consumption.

• Kermi radiator 11 5 05 (547 watts) - 2 pcs.
• Kermi radiator 11 5 10 (1147 watts) - 1 pc.

Bedroom 13.1 m2 May one day, but for equal scorching, we recommend installing two radiators:

• Kermi radiator 11 5 09 (1032 watts) - 1 pc.

Bedroom 11.1 m2 may one day But for equal scorching, we recommend installing two radiators:

• Kermi radiator 11 5 04 (459 watts) - 1 pc.
• Kermi radiator 11 5 07 (803 watt) - 1 pc.

Wardrobe 5.6 m2 may one day:

• Kermi radiator 11 5 06 (688 watts) - 1 pc.

San vuzol 4.6 m2:

• Kermi radiator 11 5 05 (547 watts) - 1 pc.

for the hallow we did not transfer the choice of radiators, to that, the options for types and options for their placement are essentially impersonal.

After that, we have designed an additional KERMI scorching radiators for the applications you need, you can choose a butt. We took for the butt a dovіlny plan of one on top. All heating radiators are scorched with the improvement of possible heat losses in the house, so the normal supply of heat output becomes 10% - up to 15%. Ale the installation of radiators in the scorching will not end only on the batteries, you also need to connect to the scorching system. For which you will need to add some additional elements:

1. Group connection (multiflex). This element can be connected to: 3/4 cap nut (for connection to the radiator) and 3/4 thread (for installation to the scorching system). The set also includes two cone inserts.

2. Thermostatic head (maє nameless different names). It will serve to regulate the temperature of the scorching batteries in order to maintain a comfortable temperature regime in the premises.

3. Fitting with a union nut 3/4 for connecting pipes to a scorched pipe to a group of connections, to be bathed together with pipes. For polypropylene pipes dodatkovo slid pridbati dvі cone inserts.

Visnovok: for one radiator of steel scorching, you need to add a group of connections 1 pc, a thermostatic head 1 pc (you will need to order for the scorch, the scorch battery can also be ordered without it), fitting with a union nut 3/4 2 pcs (as a rule, you buy at once with pipes - one fitting for pipes with heat supply, the other fitting for pipes with heat transfer to the radiator).

1. Valve from manual control. 1/2 external connection (for connection to the scorching radiator), 1/2 internal connection (for installation to the scorching system), and shut-off valves for supplying heat to the radiator.

2. Thermostatic valve. It is the same as a valve with manual control, but also allows you to install a thermostatic head for manual regulation of the temperature of the radiator.

3. Check valve with manual control, can be connected to 1/2 external connection (for connection to the scorching radiator), 1/2 internal connection (for installation to the scorching system), to serve as a shut-off valve for introducing heat transfer from the battery.

4. Fitting made of 1/2 standard cuts for connecting singed pipes to shut-off valves, to be bathed together with pipes.

Visnovok: for one radiator with secondary connections, you need to add a valve with a manual connection 1 pc (or replace a new thermostatic valve), a check valve with a manual connection 1 pc, a fitting with a 1/2 outer groove (attach at the same time with pipes).

Correctly chiming the rozrahunok radiators of scorching - it’s even more important, but it’s also not less important to equip them correctly. Our faculty will always help you with this difficult task. We will forever be for you!

Regardless of the appearance of new types of accessories, steel radiators are becoming more suitable for rich coristuvachs. Vivchimo respectfully їhnі perevagi that nedolіki, and also put the correct zasosuvannya. Krіm tsgogo, we will induce an algorithm dіy, which will help you be-yakіy people shvidko and exactly open the parameters of the radiator for the singing application.

Technical characteristics of scorching batteries from steel

The old models of radiators of this type were tubes, to which the plates were welded vertically. To improve the aesthetic parameters, such a design was covered with a plaque box. Today, such decisions are rarely victorious. Most of the construction is made of two steel plates, in which the channel profiles are stamped. The stench zavaryuyutsya, pokryvayutsya beast zahisno-decorative balls.

It is important for the Zvichay Spozhivachev to know that analogous virobi can win, so that the rozrahunok will be exact. To the very same, we victoriously gave equally technical characteristics. On the cob pererakhuєmo the advantages of steel radiators:

• Shvidke heating is good heat conduction. These parameters confirm the applicability for the installation of such batteries in automated systems scorching, which regulates the operation of the boiler in the fallow, according to the indication of a number of temperature sensors.
• Good bagging with different metals. Qi fittings can be connected to the middle and other pipelines without obmezhen.
• Lightness of one section. With an intensity of 100 W, the viability is not more than 2 kg.
• Yogo small roses are also visible. It doesn't matter if you know the space needed for installation.
• Small internal volume. You need to get into a private booth, de dbaylivy master, just to rob the rozrahunok of the necessary amount of heat.
• Chi is not high varst.

To save objectivity, let's create a list of surpluses:

• Porіvnjano small rozmіri working channels. In some vipadkah, mechanical houses of buildings are stuck with them.
• Low resistance to oxide chemical reactions.
• Low mechanical strength of the bearing and low water resistance to hydraulic shocks.
• The integrity of the design. With such attachments, it is not possible to change the dimensions for the rahunok, or to add a section. In this manner, the possibility of building an exact rozrahunok with the improvement of the area and height of the singing accommodation is reduced.

In this table, data has been added for indiscriminate pairing with other types of radiators:

Parameters / type of opaluval attachment	Chavunny	Aluminum	Bimetal	Steelium
Tightness at the heating main (max.), bar.
Tension of the section (powdered whole mill), W
Permissible heating temperature (max.), gr. Celsius

Rozrahunok batteries singed from steel

We will introduce a simple algorithm, which will help to independently develop, which is the tightness of the metal sections needed to heat the room of the singing area:

• Let's assume that the size of the feet (length X width X height) at m.: 5 X 3 X 2.8. Її obsyag become time: 5 * 3 * 2.8 \u003d 42 cubic meters.
• If energy-saving technologies (special wall insulation, rich-chamber sloppacks, etc.) are not used, then according to the norms, which are developed, per 1 cubic meter. m. This figure is suitable for the rozrahunka of the system of scorching a booth, rotting in the middle climatic climate of Russia, for example, near Pdmoskov. For work with applications in the area, you need such a hot section thermal pressure: 42 * 40 \u003d 1680 W.
• To avoid difficulties in severe frosts, rather increase the nominal value up to 20%. At a time: 1680 * 1.2 = 2016. In the model range of the virobnik, it is known that the rounded for the tightness of the virib is 2.0 kW.

On some specialized sites of sellers and a selection of radiators, such sections can be listed in automatic mode. For whom it is suggested to fill in the table or the form for the following points:

• rozmіri kіmnati (area and elevation);
• type of life;
• living/technical accommodation;
• boiler type or other heat source;
• number of old walls;
• presence/visibility of sklopakets;
• Rіven vnutrishnyoї temperature, which vіddaє prevagu koristuvach.

Peculiarities of stasis and improvement of the efficiency of scorching

Low battery inertia zі sіlі allow you to successfully vicorate qі fittings in today's individual opiation systems. Such a possession is supplemented with sensors, which control the temperature of the return and heat transfer. different points. If you take a look at these data, you will promptly decide how to change the settings. At the result - the necessary coristuvachevі rіvenі іvenі komfortієєє і podtrimuєtsya without zayvih vitrat energicheskіh resourіvіv.

Precisely matched battery sizes, the characteristics of one section will become a good thing in a be-yak slump. Ale, if the robots are not broken into an insulated booth, then all the susillas will be maritime. Vіdpovіdnі vtrat through the walls and defects in vіkonny prorіzіv nіshchat usі theoretical vіgodi. At the same time, at the stage of the selection of suitable radiators, it is necessary to overthink and use the shortfalls in insulation, the technical inadequacy of the boilers and the other opalous possession.

Indicated in the technical passport for steel radiators- Target data. Victory of the given opportunities will not always be full. If you want to get a better connection, then you can spend up to 8-10%. The lower connection is even less effective. And here the decrease in the normative indicator of the building does not reach the value of 18-20%. Tim for an hour, as it is permissible to lay pipes only in screeds, then you will have to beat the remaining option. For refilling the batteries, you can try to increase the pressure on the system with the help of a special pump, which ensures safety Primus circulation heat transfer.

Provided data to confirm - skin care for the project of scorching may be carried out individually. It is necessary to take into account the peculiarities of such warehouses: possession, life, mode of operation.

Steel panel radiators are a competitor to the conventional sectional-type scorching accessories. The stench is more important, that, porіvnjano z usіma sektsіynimi models, with smaller dimensions, there can be more high coefficient of thermal output. They are stacked from panels, at which molding moves, the heat carrier collapses. Panels can be buti kіlka: one, two or three. The other warehouse is corrugated metal plates, which are called fins. Axis for rahunok tsikh plates i reach high rіven heat supply and outbuildings.

To eliminate the different thermal tightness of the panel, the ribs are combined in decal options. Leather variant may be tighter. It is necessary to know what the skin of them is to correctly pick up the rozmіr and poguzhnіst. For household steel panel batteries, there are offensive types:

• Type 33 - trippanel. The tightest class, but the largest. There are three panels, before which three plates of the rib are added (that is why 33 are indicated).
• Type 22 - double panel with two rib plates.
• Type 21. Two panels and one plate between them with corrugated metal. qi opalyuvalni prilad with equal expansions, there may be less tension against type 22.
• Type 11. Single panel steel radiators with one fin plate. Mayut more less thermal exhaustion, but lesser air and dimensions.
• Type 10. Which type has more than one heat transfer panel. These are the least and easiest models.

All tsі types can mother raznu height and dovzhina. It is obvious that the tightness panel radiators deposit as per type, and as per size. Oskіlki rozrahuvati tsey parameter is not possible on its own, it is impossible to make a skin picker in tables, for which to enter the results of testing. Behind these tables and pick up radiators of skin application.

Significantly tightness

The tightness of steel panel radiators is necessary depending on the heat loss of the premises, in which the stench will be restored. For apartments, roztasovannyh in standard booths, it is possible to comply with the norms of SNiP, so that the required amount of heat per 1 m 3 area, which is heated:

• The application for wake-up calls is 34W per 1m3.
• For panel booths on 1m 3 id 41W.

Vihodyachi z tsikh norms, you know, how much heat is needed for heating the skin room.

For example, application to panel booth 3.2m * 3.5m, stele height 3m. Rozrahuemo obsyag 3.2 * 3.5 * 3 \u003d 33.6 m 3. Multiplying by the norm according to BNiP for panel booths, we can take: 33.6 * 41 \u003d 1377.6 W.

BNiP norms are indicated for the middle climatic zone. For other є vіdpovіdnі kofіtsієnі fallow vіd avіd avіdnіh temperatures uzimku:

• -10 about W i more - 0.7
• -15 pro C - 0.9
• -20 pro C - 1.1
• -25 pro C - 1.3
• -30 pro C - 1.5

It is necessary to correct the heat losses and in the fallows from the number of ovnishnіh walls, even though it was clear that the more such walls are, the more heat goes through them. To that it is worth it: if one wall appears in the name, the coefficient is 1.1, if two are multiplied by 1.2, if three, then by 1.3.

Let's bring in the correction for the butt. Let the average winter temperatures in the region be -25 about W, two degrees. Out: 1378W * 1.3 * 1.2 = 2149.68W, rounded up to 2150W.

And for the butt, it’s fast with a number. For the reason that the insulation was a house and a vicon in the middle, the figure was found to be accurate.

Rozrahunok radiators Kermi

Before singling out fatigue, it is necessary to swear by the brand of steel panel batteries. Obviously, you can trust leaders. Mayzhe poses competition with today's German steel radiators Kermi. Axis and rozrahuemo potuzhnist behind the tables of the th chirp.

Let's try to install one of the new Kermi Therm X2 Plan models. Behind the table, in order to indicate the tightness of all the actual models, we know valid values. Exact zbіgu shukati not varto, shukayte meaning, like trochs more nizh razrahovane (heat engineering more often than not has a small stock of "about every kind of fluctuation"). In the tables, the options that are suitable for our choice are marked with red squares. Let us have a more pleasant height of 505mm (shown to the top of the table). More for others, lesser lengths (1005mm) are added to type 33 panel radiators. Although it needs to be shorter, you can change it on a model with a height of 605mm.

The table of the calculation of the thermal pressure of steel radiators Kermi

Overpressure of panel radiators fallow due to temperature conditions

Alternately, the values ​​in this table are valid for a system with parameters 75/65/20 (supply temperature 70 °C, return temperature 65 °C, inlet temperature 20 °C). For these values, the delta of temperatures is developed: (75+65)/2-20=50°C.

If your system parameters are different, you need to change them. For similar vipadkiv, "Kermi" put together a table with corrective coefficients.

Table pererakhunku in fallow areas according to the temperatures of the scorching system (click to increase the size)

Let the low-temperature system with parameters 60/50/22 be transferred (supply temperature 60 °C, return temperature 50 °C, inlet temperature 22 °C). Important temperature delta: (60 + 50) / 2-22 = 33 about W. We know in the table a row from the temperature of the water carried out, then from the temperature of the water, which is introduced and it reaches the temperature value in the room (22 about W in our fall). This client has a coefficient of 1.73 (meanings in green color).

For a new multiplier, the amount of heat consumption for our accommodation is multiplied: 2150W * 1.73 = 3719.5W. Now you can see the correct options in the table of tensions for this type of depression (highlighted in green). The choice is modest, but the radiators need a lot of heat.

The axis is the method of determining the tightness of panel radiators. According to you, you can choose steel panel batteries for any room or system.

Podbags

To analyze the heat loss of panel radiators, it is necessary to know the heat consumption of the location, the company you want to buy, and the parameters of your scorching system (supply temperature, return temperature, and temperature in the room). For data on the tables of tension, you can designate models that please your mind. Let's choose from these options, which one is more suitable for the parameters (height / dozhina / depth). Axis i is the whole technique.
