Stereotype No. 4. Panoramic windows are inevitable condensation and icing ⠀
⠀
Condensation on properly designed and installed large format constructions will never appear. Risks can arise only if errors are made during the design and installation. ⠀
⠀
⠀
📐 Since we have large structures, in addition to calculating the glass unit for heat transfer resistance, it is necessary to calculate its deformation stability. If this is not done, then the difference in temperature and pressure between the glass panes in the glass can increase or decrease, which can lead to condensation or even icing, as well as the effect of “curved mirrors”. If the glass is selected correctly, if everything is done normally, then the risk of condensation and ice formation is minimized. ⠀
⠀
One of the most common causes of condensation is the use of an aluminum spacer in a glass pane (low temperature on the surface of the glass in the area of the spacer) and the lack of circulation of warm air, especially in the lower horizontal parts of the structure. ⠀
⠀
⠀
🔗⠀
When using ⠀
warmer distance frames in the double-glazed window (steel, TPS, etc.), the risk of condensation is significantly reduced (temperature increase in the distance of the distance frame). ⠀
⠀
Another anti-condensation solution is the optimally selected glass unit installation depth. Depending on the installation width of the profile ⠀
You can select installation depths of 18 mm, 21 mm or 25 mm. ⠀
⠀
The deeper the glass unit is in the profile, the lower the risk of condensation. ⠀
⠀
⠀
🖇 For panoramic walls and other large-format structures ⠀
We recommend making heat convectors. Directional flow of warm air from the bottom up eliminates the formation of condensate at any temperature difference. Our practice of operating panoramic structures shows: if this is done, then ⠀
there will be no condensation formations, let alone ice. ⠀

Features of the water supply system: pumping station
Economic benefits and advantages of installing a pumping station in a country house for a water supply and irrigation system. ⠀
⠀
The comfort of living in a modern country house primarily depends on the smooth operation of the water supply system, which has a number of specific requirements. This is ease of use, profitability, quiet operation and a long service life. One of the options for creating a reliable cottage water supply system and watering the site may be a surface pumping station. To understand the advantages and features of this equipment, you need to answer the following questions: ⠀
⠀
💡 What are the nuances of choosing a pumping station? ⠀
⠀
Thinking about choosing a pump for the cottage’s water supply system and suburban area, you need to be guided by the main rule - the equipment is selected depending on the type of source. Those. first, a well is drilled, a well is rummaged or a “needle” is clogged, and only then is a pump purchased with certain technical characteristics corresponding to the water supply source. ⠀
⠀
⠀
👉 If you neglect this rule, then a situation may arise when equipment already purchased just can not cope with the work. ⠀
⠀
First you need to make the following list, to clarify the selection criteria for pumping equipment. ⠀
⠀
So: ⠀
🔸 depth and type of water supply ⠀
🔸 dynamic and static level of the water mirror in the source from the soil surface (m) ⠀
🔸 Water supply source ⠀
🔸 distance from the water supply source to the house where the water consumers are located ⠀
🔸 how many floors in the house ⠀
🔸 number of consumers and their type ⠀
🔸 where it is planned to install a pumping station (in a house or on the street, seasonality of operation) and its level of elevation above the ground ⠀
🔸 Is watering planned for the site ⠀
🔸 required system pressure ⠀
⠀
If you do not answer all the points, then in the future this may lead to an incorrect choice of technical characteristics and power of the pumping station. ⠀

Ceilings: design differences
Ceilings: differences in construction. ⠀
⠀
By design, seamless, modular and decorative, or open, ceilings are distinguished. ⠀
⠀
👓 Seamless ceilings form a smooth surface that is indistinguishable from a normal ceiling. Basically, these ceilings are mounted from plasterboard sheets. This is a beautiful solution that allows you to implement such design moves as reflected light and backlight. However, with regard to the possible relocation of equipment, this solution is by no means flexible, and moreover, it requires the installation of hatches for access to the ceiling space. If the engineering communications project is not sufficiently coordinated with the architectural solution, these hatches may appear in the most unexpected places, which produces an undesirable effect. This type of ceiling is used in areas where flexible use of space is not required. ⠀
⠀
⠀
💠 Open ceilings consist of an open suspended frame to which the fixtures can be mounted at any height. This is usually a non-standard solution, unlike seamless and modular ceilings. In order to satisfy the acoustic requirements of the office space, a sufficient number of sound-absorbing elements must be provided in such a system. ⠀
⠀
❇ Modular ceilings are the most common type of suspended ceiling. They consist of a suspended grid frame to which modular elements are attached. These elements can be in the form of tiles, cassettes, panels, rails made of various materials. The lattice of the frame can be hidden or, conversely, highlighted. Various engineering equipment is decided on the basis of a single module. All elements of the system are interchangeable, which provides the greatest flexibility. The modular ceiling system is very technologically advanced for installation and operation. ⠀

Choose a self-priming pump
💠 Modern models of self-priming pumps are able to pump the suction pipe, i.e. to take away air. When commissioning such a pump, it is enough to fill the pump scroll with water. A normally suction pump is not able to displace air from the suction pipe. Before each start-up, the normally suction pump and the suction pipe must be completely filled with water. ⠀
⠀
❇ Use a suction valve on the suction pipe to prevent dry running of the pump and the suction pipe. A suction valve with a filter also protects the pump and connected systems from coarse dirt (leaves, wood, stones). If a suction valve is not used, a check valve must be installed on the suction pipe or a check valve in front of the pump. ⠀
⠀
⠀
The horizontal part of the suction pipe should have a slope towards the source of water supply 1-2 degrees. ⠀
⠀
⠀
⚖ Next, to select a station, you need to calculate how much water will be consumed by consumers. You can focus on the following approximate figures of the water flow rate: ⠀
⠀
washbasin with faucet - 0.12 l / s; ⠀
toilet bowl with flushing cistern - 0.1 l / s; ⠀
shower cabin - 0.12 l / s; ⠀
watering tap - 0.3 l / s. ⠀
⠀
⚠ Important: the usual pressure in the water supply system of a country house is up to 3 atm. Irrigation system requires more pressure, up to 4 atm. ⠀
⠀
⠀
⠀
💧 Knowing the number of taps, you can calculate the flow rate. Moreover, if the water supply system at the base of the station is planned for irrigation, then the calculation should be done with a margin, given the length of the pipelines and the number of connections - fittings, turns and reducing the diameter of the pipeline provide additional resistance. This results in a loss of pressure. ⠀
⠀
💦 To calculate the head, you need to know the distance from the installation site of the pump to the furthest point of irrigation. For reference, you can assume that 10 meters horizontally = 1 m vertically, provided that you use a pipeline with a diameter of 1 inch. ⠀

Materials for the ceiling
Materials for the ceiling. ⠀
⠀
False plasterboard ceiling allows you to effectively solve the interior of the room, but does not allow further alterations. ⠀
⠀
🔗 Gypsum, mineral fiber, fiberglass or metal are used to make modular suspended ceilings. ⠀
⠀
✴ Gypsum is a traditional material of suspended ceilings and is characterized by exceptional whiteness and high hygienic properties. ⠀
⠀
✴ Mineral fiber is a natural material. The main advantage of mineral fiber panels is their fire safety. They also have high vapor impermeability, good acoustic performance. ⠀
⠀
✴ Fiberglass is the equivalent of mineral. A feature of fiberglass panels is the ability to produce curved elements, which allows you to create embossed ceilings. ⠀
⠀
✴ Metal panels are made of steel or aluminum with a wide variety of finishes and / or perforations. They can be supplemented with mineral or fiberglass inserts to enhance their acoustic and fire properties. Metal panels are very beautiful, hygienic and durable. ⠀
⠀
✴ Metal cassette ceilings combine esthetic and functional qualities. ⠀
⠀
✴ Grilyato ceilings ⠀
⠀
Not so long ago, a new type of ceiling called grillato appeared on the Russian market. Grilyato - suspended ceiling in the form of a lattice. This is a modern ceiling design. False ceilings Grilyato open a new perspective in architecture of false ceilings. Due to its geometric structure and variety of color solutions, the grillato lattice suspended ceiling creates a variety of room design options. ⠀
⠀
The demand for Grillato cellular ceilings is growing and today there are no more modern and original suspended ceilings. ⠀

Nuances of operating a pumping station
The nuances of the operation of the pumping station and the automation of the irrigation process ⠀
⠀
Why does the pump station and water supply system need a hydraulic accumulator? ⠀
⠀
⠀
⚙ A pressure switch is used to control the pumping station. When the valve opens, the pressure drops in the system (usually less than 1.5 atm.), And the relay switches on the pump. When the tap is closed, the pump continues to pump water until the pressure exceeds 3 atm, after which the relay switches off the pump. Those. Each time the valve is opened, the pump switches on. To reduce the frequency of turning on the equipment and reduce pressure surges (hydroshocks), a storage tank - a hydraulic accumulator - is placed in the system. Thus, when the tap is opened, water under pressure in the tank will flow out of the mixer until the pressure drops to 1.5 atm, and the pump turns on again. ⠀
⠀
⠀
💧 The larger the volume of the accumulator, the less often the pump will turn on, which will reduce its maximum number of starts per hour and, consequently, increase the service life of the equipment. ⠀
⠀
⠀
To mount a lawn irrigation system on 7 acres using sprinklers. ⠀
⠀
⠀
💦 You can use a pump station to water the lawn. For example, new generation equipment, which consists of a multistage centrifugal pump, a hydraulic accumulator and a pressure switch. A feature of a multistage pump is its optimally designed hydraulics, which allows the use of electric motors of lower power at the required performance. ⠀
⠀
🛡 Modern pumping stations are equipped with thermal protection of the electric motor, protection against “dry running”. This increases their usability and service life, which is especially true when used in the irrigation system, irrigation, as well as when using collected rainwater from storm sewers. ⠀
⠀
⚠ Important: it is not recommended to water the plants with cold well water. It is better to collect water in a container, and only when it warms up, water the plants with it. ⠀

Office flooring
Floor coverings for office. Part 1⠀
⠀
Of all the surfaces in any building, the floor undergoes the greatest wear. We walk on the floor, we put furniture and equipment on the floor, drop things on the floor and spill liquids. The quality of the flooring should be evaluated taking into account its use for a long time. ⠀
⠀
🖇 Floor coverings for the office can be divided into two types - hard and soft. Hard coatings include stone, parquet and linoleum. To soft - carpet and carpet tiles. Since noise control is a very important task for office premises, carpet coverings are most widely used. ⠀
⠀
🔶 Stone materials ⠀
⠀
🔸 marble office floors офиса
⠀
Despite the fact that stone materials provide architects and designers with ample opportunities to create interesting solutions, their field of application in offices is limited. They are found in rooms such as lobbies, reception areas, corridors and toilets. Although the stone does not allow moisture and is easy to clean, its surface requires special care, as it can be scratched and also reacts to various substances, such as salt. ⠀
⠀
🔸 Parquet ⠀
⠀
This type of coating is mainly used in residential buildings. Parquet is more durable than linoleum or carpet, it has high aesthetic, hygienic, heat and sound insulation properties. However, parquet is not recommended for office use for two reasons. ⠀
⠀
Firstly, the parquet sound absorption coefficient is insufficient for the office work areas. Secondly, although wood as a material is durable, the surface of the parquet must be periodically sanded and varnished. Otherwise, in particularly busy places, parquet will quickly lose its appeal. These works cannot be carried out without disrupting the normal functioning of the office. Therefore, parquet can be found either in offices converted from residential premises, or in particularly prestigious areas where it is necessary to impress, and at the same time, the load on the floor is small. ⠀

Standards for the proper placement of septic tanks and AC ⠀
Standard distances for proper placement of septic tanks and AC ⠀
⠀
Based on the latest revisions, the septic tank should be positioned so that: ⠀
▪ The distance to the house was at least five meters ⠀
▪ At least twenty meters from the well / well, without contact of the filtration field and the aquifer ⠀
▪ It was from fifty to eighty meters to the well / well if soils with high permeability and at a shorter distance there was a danger of communication of drains and water carrier ⠀
▪ The filtration field should be one meter higher than the UGV ⠀
▪ To the border of the site was from four meters ⠀
▪ To the side of the road was from five meters ⠀
▪ Before the flowing reservoir (stream, river) was from ten meters ⠀
▪ There was thirty meters to a standing reservoir ⠀
▪ Before the underground gas pipeline was from five meters ⠀
⠀
As for aeration installations, they should be located at a distance of fifteen meters from the house, including the neighboring one. Although manufacturers claim the degree of wastewater treatment up to 98%, this is far from always true, which, coupled with dumping on the terrain, gives the recommended protection zone. ⠀
⠀
💭 Conclusion ⠀
⠀
When choosing the type of treatment facilities, it is necessary to take into account not only their technical characteristics and effectiveness, but also existing distribution standards. Slightly reduce the distance when the site is small, it is only possible on stable soils, if there is no threat of runoff entering the water intake or the overhead water. Recently, cases of fines for environmental pollution by owners of private treatment facilities have become more frequent. It is better to immediately choose the best option, taking into account the limitations, than to hope that it will carry. Even if it blows and is not fined, it’s not pleasant to pollute its own land. ⠀
⠀
@energo_doma : Install the septic tank or AU correctly! ⠀
Septic vs aeration plant
In the conditions of a suburban village: ⠀
🔸 The cesspool will not allow neighbors to do ⠀
🔸 It is unrealistic to export absolutely all liquid effluents ⠀
🔸 Therefore, two options remain - septic tank and aeration unit ⠀
⠀
🕋 Septic tank - is intended for the accumulation, settling and partial treatment of domestic wastewater in a private sewer system. It is a tank with two or more overflow chambers or several series-connected single-chamber tanks. ⠀
⠀
⛓ Collection and sedimentation for cleaning of mechanical impurities is carried out in sealed chambers, partially treated effluents enter the filtration wells (tank without bottom, with backfill) or into the fields (pipes) of soil filtration. The discharge of settled effluents to the surface, even into ditches and ditches, not to mention the relief, is strictly prohibited. Septic tanks are non-volatile and can be either factory-made (plastic multi-chamber installations) or home-made. ⠀
⠀
⠀
The septic tank is relevant for homes with year-round use, as well as for cottages that are visited on weekends or in warm seasons; volley discharge is not critical for it. ⠀
⠀
ЭAeration plant - also designed for collecting, settling and cleaning domestic wastewater in the sewer systems of private houses. But unlike a septic tank, sewage treatment is not due to sedimentation and natural biological processes, but thanks to aerobic bacteria. In addition, aeration plants have a very high degree of purification and discharge into drainage ditches is permissible, which is convenient for small areas where it is problematic to organize a filtration field. However. ⠀
⠀
⚡ AC is volatile. ⠀
⠀
During a seasonal visit or at the "weekend cottage" the installation may fail, because due to the uneven flow of sewage, especially in winter, activated sludge "will die and it will be carried out." ⠀
⠀
💦 Not always able to withstand volley discharge. ⠀
