The intensity of heat supply per square meter. How to loosen the heat tension per square meter

Rozrahunok of energy supply of plivkovo і infrachervono ї teploї podlogi

It is easy to pay for electricity bills for robots and infrared heating bills. Well, it’s true, there’s a trace of a future robotic regime heating systems and logs: cilodobovy or primus. For the first time, the windshields will be high, but in such a regime, only 1 out of the skin of 5 housekeepers will corrode, as they have installed infrachervona heat supply. On the right, the fact that most of us spend the main part of the day on the robot, the children at the school, to keep the temperature comfortable in an empty apartment is not necessary.

And now let's move on without a hitch to the rozrakhunkiv. Also, we have a room of standard size - 20 sq. m installation of plivkovo ї heat podlogi. For the rules of laying infrared system heating there is no need to lay thermopile over the whole area of ​​the room (with a heat, dosit 50%). Until then, the warmth of the underlay is not guilty of rotting under the furniture (it is not economically economical and not “receiving” for the furniture itself).

Father, we appointed that plivkova heat pidloga we will occupy half of the room, tobto 10 sq. At the same time, a thermostat is installed along with the infrared heater, which can reduce energy consumption by up to 35% of the declared pressure of the heating pad. In this way, the energy saving coefficient becomes 0.35. One square meterіnfrachervonoї teploї podlogi maє tuzhnіst 220 W/year. Important energy saving:

(10 sqm x 220 W/year) x 0.35 = 770 W/year

The price of 1 kW of electricity in Moscow becomes 5.00 rubles. Now, how much will it cost us to operate the infrared heat supply:

(770 W / year x 5.00 rubles): 1000 W = 3.85 rubles / year

As a proof, the work of heat and cold from the majority of housekeepers borrows no more than 5 years for production. Tse means that you need to pay 19.25 rubles. For the month of the week here 580 rubles (already for the holidays, if the heat of the day can function longer).

Dovidka

One thing, about what should be said in more detail - the coefficient of energy saving is 0.35, which is safe thermostat for heat supply. Deyakі spozhivachi ask: why is such a figure ordered? On the right, in that the principle of operation of the thermostat is in the offensive - the heating of the infrared heat of the sublog is heated to the set temperature in 10 seconds to 1 hvilin. After that, the thermostat will automatically turn on the heat and allow the natural cooling of the thermopile. This process is borrowed from 2 to 10 hvilin (fallen from the stage of thermal insulation of the booth and the newly set temperature). It dawned on me that at this hour the pivkov’s pidlog does not save the energy in the fire. If the temperature sensor is used, the thermostat is switched on again for the next time and the heating is restarted for 10 to 60 seconds. Let's re-enable soon. Yak bachimo, the coefficient of 0.35 is an average indicator of real energy saving.

The heat of the water underlay is vicorated as the main scorching system or as an additional heating system. Water heat supply will require lower parameters of heat transfer. The system distributes heat as efficiently as possible throughout the entire application. Before installing a warm water heater, unpack all components. Let's take a look at the design of the warm water supply, and also add pressure to it.

Heating water system includes in my own:

• dzherelo heat transfer(Installation of the boiler or central combustion);
• collections(selection and rozpodіlnі);
• trumpet;
• possibility supplementary installation kit temperature not regulated.

In a system of heat water, hot water can be vicorated, or special water (antifreeze, ethylene glycol) as a heat carrier that is heated in the system. One of the main elements of the system is trumpet.

When rozrahunku teploї vodnoї podlogi obov'yazkovo sled vvchiti all the characteristics of the pipes, which vikoristovuyutsya. You can win the trumpet:

• metaloplastikovі - іdealne pєdnannya tsіni i akostі;
• foam propylene, which may have low thermal conductivity;
• mid pipe - vіdmіnna teploviddacha, ale high vartіst;
• corrugations.

If the heat of the water supply is victorious as the main scorching system, then there is a need for serious charges, to that it is necessary to spend heat and spend budіvl It is better to entrust the bills to fakhіvtsy, as they may know at the gallery of hydraulics.

Rozrahunok sweating warm water podlogi

Before rozrahunka warm water, the following conditions should be taken into account on the following parameters:

• accommodation area;
• application characteristics(bazhana temperature, wall material, vicon design);
• type of underwriting, so why will the sublog be broken. So, when covering the bases from a whole board, you need a higher heating rate for the premises.
• pressure of the cauldron, pump, pipe diameter.

Factors to add to the pressure of warm water pipes, as well as help to open up the pipes, which are necessary for heating the room and stand between the coils of pipes. If you spend 100 watts of heat per 1 m², then it is necessary to insulate the room in the first place. The heat loss can reach 80 W if the thermal insulation is poor.

Rozrahunok heat water a sprat of stages.

1. Necessary paint the plan for the application on arkush paper, shortened to millimeters, setting the scale. The plan may be able to re-roof the windows of the doors.
2. Rozrahunok kroku pipes(singing gap between pipes when laying), їх rozashuvannya and diameter.

Passing through the pipes, hot water consumes part of the thermal energy, passing through the most important materials. As a result, the temperature drops and it heats up unevenly. With a short length of pipes, the pipes can be cold. For the great length, on the contrary, the water circulates badly around the system. Surface temperature not guilty buti vishchoyu for 30 degrees.

The contour of the pipes when laying maє buti no more than 80-90 meters. Chim dowsha pipe, Tim bigger hydraulic opir. With an increase in dozhina, trumpet that great number of turns in the opera of growth. The heating area can be changed to 20 m². How can I take great area then you need to divide it into two contours, or divide into three or more contours. If you see a number of circuits, then buy a collector with a singing quantity of water. Shorter version- ce manifold with control valves, this helps to change the temperature, and means to regulate the supply of heat to the skin contour.

The value of the hydraulic support may be the same for the skin contour, which is the connection to the separate collector. For other accommodation(balcony, veranda) independent contours. Tsі pіschennya guilty scorched okremo, to that on їkhnіy іgіv yde it's a lot of heat.

Vіd kroku pipes to lay down equal rozpodіl heat that is necessary dovzhina pipes. The middle part of the pipes is folded 5 running meters per 1 m² area of ​​​​application, as if between coils of 20-30 cm. Tobto, it is necessary for about 100 m of pipes for an area of ​​20 m².

To reach the heat output of 50 W per square meter, the pipes are responsible for the heat transfer 30 div. If the heat transfer is moving up to 80 W, then it is the fault of changing up to 20 cm. move the heat transfer temperature

When placing pipes for scorching warm water pipes on the plan, do not forget about main areas of heat input, yakimi є vіkna ta dvorі. The pipe that enters the riser can pass through the window. Vіdstan vіd pipes to the walls is to blame for becoming 20-25 cm, but not less than 8-10 cm. Behind the armchairs, the contour of the pipes is covered number of pipes, necessary for laying . Dodatkovo, it is required to add two meters for bringing the pipe to the riser.

When choosing a pipe laying method, heat losses can be avoided.

Parallel way, otherwise the sight of a snake. Tsei internal walls, for example, at the bath room, or at the room, de insulated outer wall. From the look of hydraulics in an economical way. The first coils of pipes are roztashovuyut bіla stіn and vіkon, to the fact that the maximum heat transfer temperature is fixed on the cob of the pipe. In this way, there is an uneven distribution of heat.

Croc laying pipes Okremo for skin application. If the laying position becomes larger than 30 cm, then it can lead to uneven heating of the logs. The optimal distance between pipes is 30 cm. For this reason, it is also important to consider the route of pipe laying. Such a way of laying pipes in small and medium-sized accommodations.

For great prim_schen vikoristovuyut spiral way of pipe laying. Tse folding, ale efficient way pipe laying. Ale, with such a laying, an even distribution of heat came out on all surfaces.

With this method, they sing more quickly accommodation with cold shinning walls to that the cob and end of the trumpet are entrusted one by one. For the fluctuations of this achievement of one cycle, it is compensated for by the heating of another cycle. Croc laying can become 10, 15, 20, 25, 30 and 35 cm, but for skin application, it is okremo. In quiet places, de spend big heat (vіkna, dverі), krok stowage quickly up to 15 div.

The trumpets are closed at intervals of approximately 1 m for help reinforced lines or clips. Or put the reinforcement on the grid on the heat-insulating ball and attach the pipes to the grid for an additional dart.

. After laying the pipes, the pouring begins. For pouring vikoristovuєtsya sand and cement at spіvvіdnoshnі: one part of cement and three parts of sand. Quantity of materials to deposit tovshchina to a sphere of a coupler.

When re-roofing the pipe contours, it is necessary to repair the pipes in the package, in order to eliminate excess materials and optimize the repair. Don't forget about varto maximum margin per pipe loop. Vaughn is not guilty of overvischuvat over 15 meters.

Remember about the cost of heat inputs of the plant. You can pierce yoga for pet thermal comfort. It is also necessary to remember about the freezing temperature and the surface temperature of the warm water supply.

Additive robots

Waterproofing

Before laying pipes, it is necessary build waterproofing pads, having announced the waterproofing pad in such a way that the vologer could not take the bait.

Shape of thermal expansion

A damper line is glued along the perimeter of the application with a method of expansion compensation cement-concrete screed. When choosing materials, it is necessary to ensure that the materials can expand thermally differently, so that they increase when heated and change when cooled.

Thermal insulation

It is important to work out the thermal insulation of the underlays, the shards of spending thermal energy through the underlay can become 15 - 20%. As heat-insulating materials, vicorous mineral wool, slate, foam concrete, technical cork, extruded foam polystyrene. Better vikoristati yakіsnі insulating materials If there is an infamous place at the bottom, then the heat-insulating ball can become a few centimeters. And if the place below is not scorched, then the height of the heat-insulating ball can reach 20-25 cm.

In the rest of the hour, this kind of heating the premises becomes even more popular. Increase the heating cable tension so that the system for heating the heat pipes in the process of work has given all the comforts. Therefore, the heat of the sublog can heat the premises in the required world without the overworld electricity supply.

For heating, the application of heat can be used as the main or additional source of heat. The cable heating system, as a vikoristovuvatimetsya for the application as the main source of heat is due to the mother's pressure of 160-180 W/sq.m. At the premises, deheating of the underlay, with an additional heater, it is necessary to tighten the tightness of the heating cable 100-150 W/sq.m.

In order to loosen the necessary tightness of the cable, it is necessary to identify the core area of ​​​​the application. Korisna area - the price that, on which a cable is laid without intermediary, without fixing the area occupied by stationary furniture (shafa, sofa, pedestal).

For example, if you have a room of 16 sq.m, with a sofa of 2.5 sq.m and a wardrobe of 1 sq.m, then the square of the area becomes 12.5 sq.m.

Vihodyachi s vyplyvaet what has been said, scho, tightness of the heating cable for the application, de heat of the pidlog yak:

• - basic warmth:

P \u003d 12.5 (sq.m) * 160 (W / sq.m) \u003d 2 kW;

• - addendum:

P \u003d 12.5 (sq.m) * 100 (W / sq.m) \u003d 1.25 kW.

Any heating cable can have its own sweating- the intensity of one meter of cable (for example, 20 W / m). Deyakі kuptsi, zastavshi pet and pursuing tightness, priyshovshi to the store, ask to sell them stіlki mіv cable. However, when buying a cable, spiraling on the shoulder strap, there is no trace!

In addition to the fact that cold and hot pipes are connected with special couplings, heating cables are sold with fixed coils (various tightness). Cі vіdrіzki can not be zbіshuvati or change, shards installed by unqualified personnel of terminals and good muffs can become the cause of an early exit of the cable from the fret. Also, when the cable is cut, a warranty is taken from the new one.

Therefore, the main indicator, which is regulated when buying a cable, is not the footage, but the tightness. For example, if you have a power increase of 2 kW, then the next power supply is 2.08 kW, the starter is 140 m-code.

On this day, it is possible to cover a wide range of cable heating systems, it is not the fault of the problems due to the choice of type and tightness of the cable. Tim is more, that more stores have a tighter cable to cover the sellers as a cost-free service.

How to loosen the warmth of the bed with your own hands

After that, as you are designated as a heat source, you will have installed an electric heat supply (main or supplementary) and if you have a heating element, you can proceed to the laying-out. It is also important to do the right thing before installation rozrahunok warm state with the improvement of heat inputs and the core area of ​​​​the place where it is heated.

Rozrakhovuemo krok laying the heating cable

After that, like a cable, for this even laying, it is necessary to loosen the laying cable. Krok laying - tse vіdstan mіzh laying parallel to the lines of the heating cable.

h laying length (mm) = (S heating area * 1000) / (L cable length)

For our vipadku: (12.5*1000)/(140) = 90 mm.

As a result, it is necessary that the cable should be laid with a 9 cm spacing. Before the cob of laying, it is necessary to paint a laying plan.

Podіgіv podlogi is becoming more and more everyday rіchchyu in our booths. They play a pidlog for the help of water scorching, putting the pipes in a screed, or electricians - rіznih heating elements, like electricity is converted into heat. It is far from possible to get water heat under the water - in old apartments it was impossible to take it off. With an electric power, you can easily know the option to navit for old crossovers, which gives the minimum preference. Ale, it was warm at the booth, obov'yazkovo zazdalegіd rozbity razrahunok elektrichno ї teploї podlogi. These vitrati on obshtuvannya will be optimal, and tightness enough to induce for the coldest periods.

Rozrahunka techniques

We need to be appointed, you will have the main scorching heat (without radiators and other heat sources) or supplementary ones (for increasing comfort). Fallow in the event of a change in the distribution of electrical heating supplies. As a rule, pіdіgіv pіdlіv - lіѕ аlѕо additional scorch, єdina vimоg - tautness mає stаchiti in order to heat the pіdlogu to comfortable 28.5-29°C. There are no others who can. For such a layout, they are boldly corseted with average figures, designated by an additional path (at the table below). When vikoristanny pіdіgrіvu pіdlogi as osnovne scorched, pіdkhіd іnshiy: heat may be sufficient to compensate for heat losses. There is something more folded here - you need roses.

Rozrahunok elektricheskaya teploї podlogi for heat losses

There are two ways to grow the electrical heating supply. The first one is the rozrachunk itself. From the point of view of the principles of the methodology, the heat loss of the premises is determined. When the region is protected, in which the life is known, the material and the fabric of the walls, the fabric and the type of insulation, the expansion of the window and the type of slope, the appearance of the area of ​​the walls that overlook the street, the orientation of the accommodation (on pivden, pivnіn). All these factors are poured into the amount of heat that comes from the place and how it happens to be filled.

The heat loss of the skin type of the budive material can be found in the special literature, and also in the methodology. Such a rozrahunok is boring on the right, ale wine allows you to take exact data. Tse on vipadok, like you want to rahuvati yourself. If not, then you can get a heat engineering rozrahunok from fakhіvtsіv. I, as the area for heat under the log is planned to be large, more beautiful. Sometimes, independently sing heat losses in times, you will see fahivts. And zayvu tightness - for free stained pennies.

The figure will be taken off by the intensity of the electrical heat supply, as it is necessary to compensate for the heat loss of this facility. All electrical heat protection is due to the fact that you need to pick up the heating elements in such a quantity and such a tightness, so that the stench could see the total amount of heat required (it is possible with a small margin). If there will be heating cables, it will be possible to expand the laying scheme in such a way that the entire required cable footage is laid out on a given area. It is as if it was victorious to beat the plethoric warmth of the pidlog, requiring the thrashing of the plethora of the necessary tightness. If you feel like it, lie, so that in order not to feel the coldness with your feet, that hot heat, stand between the dry heating elements, it’s not your fault, but more than 30 cm. 3 cm, closer to 5 div.

Get respect! Electric heat is laid only on this square, as it is not occupied by that great furniture by-butovy technology. It is connected with this, that the heating elements of the heating element and the logs do not tolerate overheating (there is a self-regulating cable that heats up). Therefore, the cost of electrical heating costs is due to the cost of furniture and equipment on the plan (at scale). Having appointed a square that is not occupied by the situation, you can proceed to the rozrahunka. Another one important moment: if the heat of the base is the main source of heat, then the surface that is heated is not responsible for less than 70% of the total area.

Significance of the necessary tension in the fallow in the presence of a recognized application

Another way is to appreciate the average statistics. A lot of materials, like vicorist, for the first hour of the life of living houses, are fenced. This gave me the ability to enter the average figures necessary strains heat pads for scorching different recognition. (Look at the table).

Searing type	Name the object	Necessary tightness
Dodatkove scorching	Kitchen, living quarters on the first version	140-150 W/m2
Dodatkove scorching	Kitchen, living quarters on another version of the same	120-130 W/m2
Dodatkove scorching	bath room	140-150 W/m2
Dodatkove scorching	Balcony, loggia	180 W/m2
Mainly scorched	Must be accepted, independent of recognition	180 W/m2

When rozrahunku elektrichnaya teploї pіdlogi found occupied area multiplied by the norm, taken from the table. Take off the figure, as you can see the electric heat supply. In principle, it will also be the maximum reduction of tension, which is necessary for the improvement of the condition.

For example, if 10 squares will be heated near the living room on the first version, then you can see / save the heating element can be 140 W / m2 * 10 m2 = 1400 W. Tse spozhivana poguzhnist for a year. Do not swear. In reality, such a vitrata can only be turned on and off, until you reach the set temperature. At this hour, the heating is done fast. Then the temperature controller turns on/off, which keeps the set temperature accurate to 1°C. The amount of electricity, which is cool during this period, to lie down in the weather (it’s colder, it will turn on more often) and the stage of insulation and the application as a whole.

What can be added to the heat supply

On those, it would be better to work on those, it would be better to practice pіdіgrіv pіdlogi, not only the tightness of the heating elements, but those, the stilts of correctly splitting and splitting the whole “pie”, as if the materials were correctly selected.

Pokrittya

We are pouring a cover onto the heat supply, as if laying on top of the heating elements. For example, it is possible to use a resistive or self-regulating cable for heating, mothers of a new or a shearing infrachervone sublog, most often they are poured into a screed. At the same time, there are special sums for the warm state. The second option is for the standard cement-packing add additives that increase the heat conductivity of concrete. Another option is cheaper, but you can find information about the necessary additives. Natomist can be spared.

Then ceramic tiles are laid on the screed - near the bathrooms, corridors, kitchens. In living quarters, the most common vicorist is laminate, linoleum, and carpet.

Nezalezhno in the same way pidloge pokrittya You are planning to come, you need to win only those materials, as they are recognized for laying on a warm bed. They may increase heat conductivity, it is normal to endure heating three times. Since the price has been raised, it has been primed, that one will be more effective.

The last choice of finishing covering for warm underlayment is carpet. Navit spetsialny, vіn hirshe for all others to conduct heat. To heat it up to a pleasant 28-29°C, raise the temperature of the heating elements by 4-5°C more, lower for other types of processing.

Next choice ceramic tiles chi porcelain stoneware. The stench may have a good thermal conductivity, but the stench is also cooled by the increased heat capacity - a good hour passes until the stench warms up. Lay the tiles and the heat needs to be applied with a special adhesive.

When using heating cables (whether they be) or shearing warm cables, the laying technology is the same. The screed is poured on the bottom, the concrete is gaining strength for 28 days, then the tiles are laid. If you choose mats from the cable, which is heated, the process changes, moreover, it is significant: the tile can be laid on top of the mats on the required ball of glue. Vitrata glue at times great (minimum ball tile + glue 3 div), but the hour needs significantly less.

Plivkov heat underlay can be worked without a screed. Yogo put under the laminate. On top of the pl_vka, a special lining is laid out (for warm lining) and a laminate can be laid. Under linoleum or the same carpet, lay out a hard base - lay sheets of plywood, chipboard or OSB, and then lay them on them finishing touch. Such an attachment of electrical heat and underlays - without a screed - is only possible at a vapadka, so radiator not scorched. Everything is laid down quickly, but the scorching is not effective - the great heat output is not within reach of the daily benefits.

Thermal insulation

The more thermal insulation under electric heaters, the less electricity is needed to maintain normal temperatures. As soon as the hour of everyday life of the pidlog was already insulated, it is possible not to lay the insulation. If you want a system - you install a cable or a plywood lining - talk about the need for a different heat-insulating lining. The stench of the different in the different systems, but the presence of the bazhan. Todi, rolyachi rozrahunok elektrichnoy teploї podlogi for the average statistics, you can take the tightness of the lower edge, or wind more trochi lower. And tse - protected pennies during power-up, and during operation (less heat is needed on non-heating).

Trochs about heat-insulating materials, yakі recommend vikoristovuvaty with the power of warm weather. The most optimal - extruded pnopolistirol (EPPS). Vіn maє suffice schіlnіst i mіtsnіst, schob vitrimat the vice of the screed and everything that is on it perebuvatim. Another option is thermal insulation, which is drunk, high thickness. The way is better, and even more expensive. The thickness of the screed needs a temple of 60-80 kg / cu. Truthfully, the best characteristics for today (thermal conductivity may be similarly 0.2-0.3 fallow in the harvester).

Often, when laying electrical heat underlays, it is recommended to use vicorist with thermal insulation with a foil surface. We argue that the foil is used to change the heat exchanger in the middle of the application. Won so and pratsyuє, but for the obviousness of the increased gap between heating it with foil (not less than 3 cm). Pyrosis has no warm underlays and cannot have any traces of prosharks. So, laying down this material is just a waste of pennies and an hour. There is one more argument against laying a foil ball under a warm bed. Foil in concrete collapses into saws through a sprat of tizhniv and becomes a familiar marna. The stench cannot grow up to redistribute equal heat in such a state.

Temperature controllers and sensors

Scheme of the electric heat and the sub-logs transmitting the presence of the temperature controller and the temperature sensor. Your presence is not obv'yazkovo - you can manually turn on that vimikati heating. But only at once with these outbuildings, the system is practicable, trivial term, provide the necessary level of comfort, rationally win electricity, unikatim overheating. On the distribution of electrical heat, do not add the presence or presence of the temperature controller with the sensor, and the axis on the term of service is even more strongly indicated. As has already been said, more important heating elements are afraid of overheating, and when manually controlled, it is even more difficult to disappear. A couple of times you won’t suddenly get wet, the cables / plіvka / mothers will melt.
