The warmth of the water. Features and vashtuvannya warm water

⁰

The article describes the power of the water heating system, shows the main features of the water heating system. We porіvnyaєmo heat for water and electricity, the system of scorching water heat for water and radiator. In addition, it is rozpovimo as a viconate of the rozrahunok of the tension of the water heat and the conditions, if you follow the vikoristovuvat system, as the main for scorching the booth, and if - as an additional one.

De-docilly zastosovuvat system of water and heat supply.

Most often, the heat of the water supply is vicorated at a private booth. With this, with the provision of warm water in the surrounding areas of the premises (bath, kitchen, bedroom) - it is easier to power the heat supply, for that in small premises it is easier to blow pipes with water, lower cable. If the heat supply system is planned as the main scorching system, or if such a system is planned to be installed on a large area (20 m 2), it is more (cheaper) to install water heat under the water.

The lining of the water heating system near the apartment of a bagat-top-covered booth with centralized scorching with heating water from the centralized scorching is categorically fenced, and the installation of the water heating system of the scorching circuit near the scorched circuit will require environmental protection from the state authorities

The design of the water heating pads (by balls).

The figures show the main schemes for the control of water and heat supply.

Scheme of vashtuvannya water heat sub-logs from fixed pipes with harpoons to the ball of heat insulation.

Scheme of the installation of heat pipes with fastened pipes with clamps to the reinforcing mesh

Scheme of vashtuvannya water heat and subsoil on the ground

Note. On three little ones, the pipes of warm underlays and the armored net above them are shown more. On little ones, nachnosti, trumpets and nets are painted on, you can blame the damage, there is a gap between them. So the axis, the gap between pipes and reinforced mesh, - no.

With small variations (various options for fixing pipes, the presence or absence of an additional screed for insulation, you can read more about it in the topics)

overlay slab (base slab). As the construction of the sub-logs of the vikonan on the ground, then the replacement of the slab of overlap will be the following balls: piping from the sand 5-7 cm (pisok can be any), piping from crushed stone fraction 30-50 mm, 8-10 cm, polyethylene plivka, black screed 7 - 10 cm (її you can not armuvati). At the black screed, the fraction of crushed stone is 5-10 mm and the river sand;
waterproofing, pasting (on the basis of bitumen with various polymeric additives, reinforced with polyester or slate) or coating (bitumen-humic mastics, bitumen-polymer or cement-polymer);
thermal insulation - pіnopolіstyrol or EPPS.

Note. Tovshchina teploіizolyatsiї vodnoї teploї podlogi u derzhnogo spečnogo vpadki znachaetsya rozrahunkom. We are such a rozrahunok vikonuemo, put food at the distribution of food-Vіdpovіd, and we are afraid;

rolled insulation with aluminum surface. It is recommended to vicorate the insulation with lavsan instead, which does not allow aluminum to interact with the concrete screed.

Note. You can not put the ball, you can put the pipes directly on the EPPS or polystyrene foam;

pipes for water heating;
the concrete screed with the addition of a plasticizer, reinforced with a mesh with a center of 100x100 mm, from a rod with a diameter of 3-4 mm.

Note. The thickness of the water screed is warm and dry (together with pipes) 7-10 cm. Recommendations are made about those that, if you put a plasticizer at the warehouse of the screed, then you can work a screed with a thickness of 3 cm, or you can not reinforce. Tse not so. When the plasticizer is stuck, the screed is to be buti reinforced, and the thickness is less than 5 cm. Larger amount of plasticizer at the screed to induce "burnout" of the screed and the appearance of cracks. You can read a report about it at the gіltsі. Armuyucha sіtka is guilty of obov'yazkovo perebuvat the beast over the pipes. Todi sitka equally rozpodіlyaє ekspluatatsіyne navantazhennya on pipes. You can make recommendations that the mesh can lie under the pipes. Ale, in this way, won’t play a constructive role, just blow the pipes manually to it (with plastic clamps). That is why the presence of the grid below under the pipes does not change the fact that it is the fault of the obov'yazkovo buti above the pipes;

pіdlogov clean pokrittya. This material is to blame for the mother of marking about the possibility of stagnation with sublogic scorching.

Features of water heat supply.

The features of the water heat supply will be considered in the following order:

Equalization of water heating pads (like just a system of heat pads, without balancing the fact that it’s “water” itself) with a radiator system. Tobto tse por_vnyannya system teploї pіdlogi (inodі all tsі systems call PSO - pіdpіlnі scorching systems) and RSO (radiator scorching system).
Por_vnyannya water and electric heat subdlogs.

Peculiarities of water heating systems, depending on the scorching system (PSO) and the scorching radiator system (RSO).

In the case of warm weather, the temperature was brought to the nearest to the optimum. Seemingly warm, I went from head to toe. If you want to see the sign of the presence of an infrared camera, you can tell that it is not evenly spreading warmly in the middle of the place.

Diagram showing the warmth of the host

On a small scale, a diagram of the distribution of heat flows near the room is shown, where a scorching radiator system is installed. The small picture on the right shows a diagram of the distribution of heat from the system of sub-scorching. According to the diagram, you can see that at RSO, in order for the temperature in the room to be close to 20 - 22 ° C, you need to overheat the hot air zone to 26 - 40 ° C warmer weather). To come out, that the radiator is hot again, as if it were beating itself, and the heat of the sublog is all over the area.

saving energy. Vikoristannya PSO allows you to reduce by 1 - 2 ° C the temperature in the room in the room with the radiator system of scorching. It is worth considering that the PSO system works at low temperatures of heat transfer (up to 55°C), while at the same time it looks comfortable. Because The emission of heat is felt through the entire surface of the underlay, indicating that the temperature is rising in the middle of the application. Only a decrease in temperature by 1-2 ° C can be allowed to save from 6 to 12% of energy. Why, for the reason that there is no local overheating behind the radiators, the heat loss through the fenced structures changes. And with different automation systems, you can regulate the temperature in different rooms differently. With the correct adjustment of the automation system for floor scorching, in parallel with the scorching radiator system, it gives a saving of 10 - 15%. And with the height of the stele over 4 meters, You will protect even more.
It should be noted that the addition of warm footings will increase the singing height of the place. The construction itself takes up approximately 130 mm (which means thermal insulation is 50 mm), and it is not possible in ready-made applications with low slabs.
installation of additional partitions with the help of the already established warm underlays, with the participation of a specialist.

Peculiarities of water heat supply, depending on the distribution of water and electric heat supply.

The term of service of water heating systems is determined by the term of service of pipes installed in the system. According to the data of manufacturing plants for polymer and metal-polymer pipes, the terms of their service can become over 50 years old. Batteries or convectors in the average are replaced after 25 years. The term of the electrical wiring service according to the standards of the manufacturing plants for the average 20-25 years, which determines the term for the service of electrical heating systems for the 20-25 years.
Water heat is more important to regulate, lower is electrical (it is due to this that water cannot be heated up-cool down, it takes more than an hour, lower to an electric cable).
In times of water heat, the pipes are more likely to spread heat on the surface of the pipes, so that a pipe with water cannot be burned with such a small crack, like a cable. In addition, water in the world of supply of thermal energy reaches and in the end of the scorched circuit can be a few degrees colder, lower on the cob. When designing water heating pads, it is necessary to pay special attention to the correct laying of the heat pad contours.
In case of an accident, it is possible to leak
With a water-heated field, the presence of a circulation pump is obov'yazkovo, in gravitational self-fueling systems, water heat cannot be controlled. The more turns (loops) at the pipes, the more important it is to pump the motherland in the system.

If the water is warm under the log, it can be the main system of scorching, and if it is more than an additional one.

The water of the heat of the base can be used as a single main system of scorching a booth, as well as an additional one. In that case, as you can see the option, if the water heat of the sublog is the main system of scorching, you can independently reverse it, which is possible. In order to make the vikonati "black" rozrahunok warm water underlays, it is necessary to work on the foot:

Calculate the heat consumption of your home (take the figure W per 1 m 2 per year). The heat losses are determined by the fallow in the area of the windows, the quality of the insulation of the walls, the depth and the underlays, the height of the beds is thin. and this unit can become 40 W / m 2 (for application with effective thermal insulation and yakіsniy sklopaket) up to 250-300 (for application with thin non-insulated walls and a large area of window openings). Calculate the heat consumption can be for the help of various programs available on the Internet.

Note. We win over the cost of expenses, put food in the distribution of Nutrition-Vidpovid, we are sorry.

Then we will need to equalize the figure of heat losses from the average intensity of the water heat supply (you can focus on 80-100 W / m 2). If so, it is necessary to vrahuvat that the water heat of the underlay cannot be spread over the entire area of your underlay (scallops are required to enter the pipes to the walls). The active area of placement of pipes for heating the heating system of water heating systems for the application, for example, at 20 m 2 can be covered by the following formula: 20 (douzhina wall 5 X 4) - 3.6 (access from the wall to the extreme point of the pipe along the perimeter of the wall is to become not less than 15-20 cm) = 16.4 m2.

For this, front, enlarged rozrahunka, it is possible to accept, scho z usієї ploshchі pіdlogi, 70% - active area (cream vіdstupіv vіd sіn, it's necessary to vrakhovuvati sсhovuvat scho to deal with furniture). If so, it becomes clear that it is possible (to cover the amount of heat loss) the area of the heating system to be placed on the area of the house, chi n. І, vіdpovіdno, otrimuєmo vіdpovіd on food, chi can the system of water heat and supply be the main one, or even more supplementary.

an example of a rosary. Let's say, spend a specific booth, with an area of 200 m2, folded 150 W / m 2. We can see that there is a possibility of an active area of warm water (70% of the total area of the booth). 200x0, 7 = 140 m2. Tse square, theoretically it is possible to spread the warmth of the bed. Now we multiply the active area by the average intensity of the heat supply (we take the figure 90 W / m2). 140x90 = 12600 watts. Stіlki "give" the system of heat stat. And now it’s okay, skilki of the whole fide from the house of warmth. I’ll cover the square of the booth multiplied by the figure of heat loss. 200x150 = 30000 watts. Now it is equal to 30,000 W and 12,600 W. It can be seen that the stosuvannya teploї pіdlogi not pokrіє vytrati tsієї koncheї oselі. Also, zastosuvannya in this way of the system of warm sub-logs, as the main system of scorching, is turned off. It is possible to vicorate the warmth of the log only as an additional system of scorching.
