Description

The invention relates to the field of construction, namely to the development of design solutions for the creation of energy-efficient, environmentally friendly buildings and structures that maintain a given air temperature, and can be used in the construction of structures for heating and / or cooling of premises in residential and industrial, warehouse premises, in livestock farms, in greenhouses for heating the soil when growing early vegetables using pipes with a coolant or coolant passing through them.

Known energy-efficient building according to the patent of the Russian Federation No. 131752, class. Е04В 1/02, Е04Н 1/00, 2013, according to which the high energy efficiency of a building is provided, for example, by means of the construction of a floor slab and the construction of load-bearing multilayer walls.

When manufacturing a floor slab either in the factory or directly at a construction site in the manufacture of a monolithic floor slab, reinforcing frames with embedded parts are placed in the body of the plate so that some embedded parts are placed flush with the outer plane of the end face of the floor slab. And others are flush with the upper and lower planes of the floor slab.

Between the reinforcing cages in the floor slab, nests are made, into which then, when installing the floor slab, insulating inserts are laid.

After the installation of the floor slab, a self-supporting enclosing multilayer wall is mounted.

To do this, a heat-soundproof substrate is laid on the surface of the floor slab on the surface of the building, onto which a U-shaped piping is also installed around the entire perimeter and fixed to the floor slab. Then, in a U-shaped strapping with a certain step, C-shaped racks are installed with pre-crimped ends, which are made not only for convenience, but also for reliability and accuracy of installation.

On the outer end of the floor slab to the embedded parts fasten the supporting structure of the facade.

Between the C-shaped racks, the first heat and sound insulating layer is laid to their entire height, then the first facing inner layer, the vapor barrier and the second facing inner layer.

After that, from the outside of the self-supporting enclosing multilayer wall, a second heat and sound insulating layer is installed, a windproof layer and a facing facade layer is mounted on the supporting structure of the facade.

Depending on climatic conditions, the self-supporting multilayer wall is made of different thicknesses by using one or two metal profiles for the C-shaped rack and due to their different connection.

The wall design meets the basic requirements of future home owners - warm, economical, reliable and quick-build.

In general, the proposed frame-panel construction technology has the following advantages: high construction rates; the possibility of building at any time of the year without losing quality and increasing the cost of work; manufacturing of building components with high factory training and accuracy; during the construction process, special equipment is not required, since the parts of the frame are small and light, the house is assembled by the efforts of a team of 4-5 people; the ability to keep the landscape of the area and the vegetation available on the site intact; high heat and sound insulation properties of the structure; environmental friendliness of the materials used; a wide variety of architectural and planning solutions and interior decoration, the ability to use any materials for finishing the facade of the house.

However, in the construction of the building, energy saving is given to walls and to a lesser extent heating floors.

Known energy-efficient and environmentally friendly building according to the patent of the Russian Federation No. 80486, class. Е04Н 1/00, 2009, adopted by the applicant for the prototype, according to which an energy-efficient and ecological building is being constructed as follows.

A foundation is being erected on the selected and marked area, for which screw piles are installed in the indicated places, exposing them at the same level. Then, to create a single foundation, all screw piles are connected together by a strapping beam, either metal or concrete.

The base is mounted on the erected foundation, collecting it from three layers, while the base panel is fixed directly to the foundation. After that, walls are erected, the panels of which are connected to the base panels. Beams are installed inside the walls, connecting them together with a connecting element and fasteners. The voids between the ordinary beams are filled with insulation. And the corner of the wall, where the beam and wall panels are also located, is connected by an end connecting element. To give a certain rigidity to the building, the lower and upper ends of the assembled walls are connected with a strapping beam.

Then mount the ceiling, also made of standardized panels, laying them on the assembled walls and connecting with the strapping beam. After that, the elements of the roof and roof are erected. The building is assembled. They begin to finish the interior, including installing a ventilation and heating system, which includes a warm baseboard. It is installed around the perimeter of the room. The heat emanating from it quickly heats the floor and walls of the room and maintains a constant temperature throughout its height.

The technology used in the construction of the described building: frame-panel, is an expedient and effective solution that gives significant savings. One of the components of which is the use of a wooden and metal frame based on light steel thin-walled structures. And also the use of the foundation with the use of screw piles: it is economical, allows you to completely abandon earthworks. Work can be carried out at any time of the year, even in winter. Foundations using screw piles can significantly save construction time, significantly reduce costs by 30-50%, and it is much more rational to solve environmental issues.

In addition, the wall design meets the basic requirements of future home owners - warm, economical, reliable and quick-build. High energy-saving characteristics of the house from heat-insulating panels are achieved through the use of modern materials and a warm baseboard. It creates a climate that positively affects human health:

- evenly distributes heat in the room;

- heats the floor and walls;

- saves up to 40% of energy;

- easy to install;

- allows you to quickly change the temperature, including using modern automation.

The disadvantage of this building is that the construction technologies used require improvement in terms of their insulation system using new materials and construction technology.

Known electrically heated floor according to the patent of the Russian Federation No. 2144612, class. E04F 15/18, 1999, containing a heat insulating, underlying, heat storage layer, a coating and carbon tape heating elements connected in parallel. The floor is made monolithic on a single basis, and carbon tapes, characterized by a width of 15-100 mm and a linear electrical resistance of 2-20 Ohm / m, are located between the underlying and heat-accumulating layers uniformly over the floor area so that the ratio of the width to the length of the tape is 1:10 - 1: 125, and the ratio of the total area of the tapes to the floor area is 0.2-0.9.

The electrically heated floor of this design, providing a comfortable thermal regime on the floor surface, is safe due to the use of ultra-low voltage of 12 or 24 V, is environmentally friendly, durable and reliable in operation, since carbon tapes are used as heating elements at a temperature of 50-70 ° С on the surface tapes can work continuously for more than 40 years, it saves energy due to the optimal choice of geometric ratios of carbon tapes.

The main disadvantage of this electrically heated floor is that the use of carbon tapes as a heating element and placing them between the underlying and heat-accumulating layers uniformly over the floor area develops a large power, which leads to an increase in temperature on the floor surface much higher than optimal.

A device for heating and / or cooling premises according to the patent of the Russian Federation No. 2178122, class. F24D 3/14, ЕВВ 5/10, 2002, adopted by the applicant as a prototype for a temperature maintenance system in a building.

And also thanks to the proposed solution, the set temperature is evenly distributed over the floor area, warming the floor to the set temperature. Using the proposed technical solution allowed to create a device containing a structure to maintain a given uniform temperature of the floor surface.

In FIG. 1 shows modular heating mats with options for placing thermal elements in them;

in FIG. 2 is a section AA in FIG. one;

in FIG. 3-fragment of a section of a building with a "warm floor" in the context.

The creation of an energy-efficient and environmentally friendly building begins with the development of a project in which the parameters of all elements of the building, the microclimate conditions, including ventilation and heating, are laid down. Great attention is paid to maintaining the set temperature in the premises of the building and structure.

The structural elements of the structure are erected in the technological sequence, namely, the foundation is built on the foundation of the building 1. On the foundation 1, the base 2 is mounted and walls 3 are erected in the same technological sequence, the roof and the roof are mounted (not shown). In the erected building, a ventilation system and a heating system and maintaining the set temperature of the building are installed, through which the necessary microclimate is created in the premises.

The temperature maintenance system in the building contains a heating device, which is equipped with thermal elements 4 designed to heat and transfer heat to floor 5 of a given temperature either by directing the flow of coolant, or by means of a heating element 6, which is made in the form of a wire and / or spiral.

In the case of the construction of a structure designed to create a cold microclimate for storing food products, for example, industrial refrigeration chambers, the thermal elements 4, after some refinement, are also able to cool the floor 5 and transfer to it a cold of a given temperature by directing the flow of refrigerant.

Similar devices can also be used in the construction of ice rinks, hockey courts, etc.

The device for heating the room is made in the form of a heating mat 7 with a heat-insulating layer 8 and a heat-accumulating layer 9, and the thermal element 4 is made in the form of a corrugated thin-walled tube, mainly stainless steel, and is placed in the heat-accumulating layer 9 of the heating mat 7 between two metal grids 10 and 11, which are mounted on the spacers 12.

Inside the heating element 4, a heating element 6 is placed in the form of a wire or spiral, which is made of a heat-resistant and chemically resistant alloy of rare-earth metals alloyed, mainly from nichrome X20H80, and the free interior of the thermal element is filled with a finely ground mixture of non-conductive electricity, refractory, refractory materials, mainly oxide magnesium MgO.

Magnesium oxide serves as a heat conductor from the heating wire or spiral to the walls of the thermal element 4. In this assembled state, the thermal element 4 undergoes radial rolling, as a result of which its diameter decreases, and the filler in the thermal element 4 is compacted. Such a technological operation allows, when voltage is applied to the thermal element 4, it instantly warms up and cools down for a long time when the power is turned off.

The heating mat 7 is made modular in the form of a multilayer panel, the lower layer of which is the heat-insulating layer 8, and the upper layer is the heat-accumulating layer 9. The heating mat 7 is designed to cover the prepared floor 5 of the room, transfer heat and further heat it. The thermal elements 4 of the stacked modular heating mats 7 are interconnected in parallel or sequentially, and the stacked modular heating mats 7 form a heated floor.

The heat-insulating layer 8 and the heat-accumulating layer 9 are made of encapsulated porous aggregate, mainly expanded clay, and the heat-insulating layer 8 is made of aggregate fractions 5-16 mm and a thickness of at least 20 mm, and the heat-accumulating layer 9 is made of aggregate fractions 3-10 mm and a thickness not less than 3.5 diameters of the thermal element 4.

The thermal element 4, made in parallel rows with a pitch of 250-350 mm, is placed in the heating mat 7 and is oriented either along or across the heating mat 7.

The distancers 12 are installed on an already prepared heat-insulating layer 8, and the thermal elements 4 with metal grids 10 and 11 installed on the distancers 12 are placed inside the heat-accumulating layer 9.

Ready thermal element 4 is not afraid of moisture, mechanical damage and is absolutely safe to use.

The heated floor, assembled from heating mats 7 with the used thermal elements 4, has the following advantages:

- it is reliable, because the heating thermal elements 4 withstand ultra-high mechanical loads, has high heat dissipation at low power consumption, is reliable due to the parallel connection of the thermal elements 4 to each other, namely, if one fails, the others continue to work;

- safe because the connection of the thermal elements 4 is equipped with hermetic waterproof couplings and has double insulation of the power cable, which increases mechanical protection and provides additional electrical safety;

- universal, as heating mat 7 is applicable both for heating and cooling rooms, porches, soil, and for all types of outdoor areas and is effective in all climatic zones, since it uses an anti-freezing coolant, refrigerant or electricity, it can be mounted under any road surface: screed, concrete, paving slabs, stone, asphalt, soil, etc., and the proposed design makes it possible to make and use a heating mat of any size.

Energy-efficient buildings are constructed as follows.

In the technological sequence, the foundation 1 is erected, the base 2 is mounted on the erected foundation 1, and then the walls 3 are erected, the ceiling, roof elements and the roof are mounted. Then they proceed to the interior decoration, including installing a ventilation and heating system, whereby the floors and walls of the room are heated and the set temperature in the premises of the building is maintained.

The heating system of the building includes a heating device that maintains the set temperature in the building. To heat the floor and transfer heat to it, heating mats 7 are used, which are modular in the form of multilayer panels, which are laid on the prepared base 2 with a waterproofing heat-reflecting layer 13 and connect them to the power supply system of the structure.

Each modular heating mat 7 is provided with a thermal element 4 and is made with a heat-insulating layer 8 and a heat-accumulating layer 9, which are made from sieving into fractions of 3-16 mm encapsulated porous aggregate, mainly expanded clay. The porous aggregate is bonded together by a cement-adhesive composition only in the places where the capsules come into contact. In this case, the laying of aggregate layers is carried out in layers and continuously in fractions. The heat-insulating layer 8 is laid from a filler of fractions of 5-16 mm, and the heat-accumulating layer 9 is from a filler of fractions of 3-10 mm, the heat-insulating layer 8 being made with a thickness of at least 20 mm, and the heat-accumulating layer 9 with a thickness of at least 30 mm and at least 3 , 5 diameters of the thermal element 4.

For the manufacture of the heating mat 7, a mold is used in which the heat-insulating layer 8 is first laid, and then the spacers 12 and two metal grids 10 and 11 are installed on it, between which the previously prepared thermal element 4 is laid.

After that, the heat storage layer 9 is laid. The heating mat 7 is ready.

The thermal element 4 is made in the form of a corrugated thin-walled tube, mainly made of stainless steel, with the possibility of heating and transferring heat to the floor either by directing the flow of coolant or refrigerant, or by means of the heating element 6 in the form of a wire or spiral, which is placed inside the thermal element 4 and perform from heat-resistant and chemically resistant alloyed with rare-earth metals alloy, mainly from nichrome X20H80. And the free space in the thermal element 4 is filled with a finely divided mixture of non-conductive electricity refractory, refractory materials, mainly magnesium oxide MgO.

The thermal element 4, regardless of how the heat is transferred to the floor and its further heating, either by directing the flow of coolant or refrigerant, or by means of the heating element, is placed in the heating mat 7 in the form of parallel rows with a pitch of 250-350 mm and orient it either along, or across the heating mat 7.

The heating mats 7 made in this way with the heat-insulating layer 8 are laid on the waterproofing heat-reflecting layer 13 of the base 2 and are connected to each other in parallel or sequentially by means of tight couplings, connectors and a power cable, after which they are connected to the power supply system of the structure.

The heating mat 7 is made modular by a given design, that is, sizes that are multiples of the dimensions of the room in which the finished mats 7 are laid.

Laying the heating mats 7 the construction of the building does not end, but this operation is a very important step in creating energy-efficient and environmentally friendly buildings.

The use of expanded clay screenings when laying the layers of the heating mat with a small variation in the granule size makes it possible to obtain the most uniform desired thermophysical and structural properties of the product. Bonding granules of encapsulated expanded clay together with each other in a monolithic composition occurs due to the active hydration of cement glue and thermal protection of the laid mass of the mixture. The set of strength of the stacked array does not require vibration, pressing and additional heat treatment and occurs at positive temperatures in the range of 15-25 degrees. To preserve the heat generated during hydration of the cement-adhesive composition, freshly laid lightweight concrete is covered with known heat-insulating materials.

High ecological purity of such building mats is achieved through the use of environmentally friendly natural raw materials and low consumption of cement component, which leads to its high thermophysical, structural and operational properties, such as: low bulk density of 450-700 kg / m ³ , good sound insulation, good thermophysical properties, air and vapor permeability, uniform structural properties, high environmental cleanliness, high fire resistance and durability.

Using the proposed technical solution allowed us to develop a project of a building and structures with maintaining a given indoor temperature, a system was developed to maintain a given indoor temperature and a heating mat containing a heating element to maintain a uniform floor surface temperature.

The room temperature control device works not only with internal temperature sensors, but also with an external temperature sensor.

Thus, the proposed system for maintaining the set temperature allows you to create a highly efficient system of heating or cooling the floor, used in heating residential and industrial premises. It allows you to reduce the volume of coolant and, accordingly, reduce the cost of fuel and energy, reduce the time of heating, cooling and, accordingly, the reaction time to changes in heating loads, and also simplify the design of the system and its operation.
