Indoor units come in several forms, depending on how they are installed: wall, floor, floor-to-ceiling, ceiling, window, cassette, duct. ⠀
⠀
⛓ Channel air conditioning is the only one that can supply air from the street, combining the functions of a split system and a fan. A multi-split system involves connecting several internal units to one external unit. Wall-mounted air conditioners are mounted on the wall under the ceiling and are the most common model. ⠀
⠀
⚙ The column-type split system has a height of up to 2 meters and is used to cool air in large rooms: cinemas, banquet halls, restaurants. Floor and ceiling systems can be mounted both on the ceiling and below on the wall. A cassette-type air conditioner distributes air in four directions and is mounted behind a stretch ceiling. ⠀
⠀
🗝 The choice of air conditioning is determined by the design and size of the room. When choosing a split system, you must also correctly calculate the power of the air conditioner, take care of professional installation and think about the location of the air conditioner. ⠀

🗣 "Nothing beats the feeling when on a winter Sunday morning you are standing with a cup of coffee in your hands in front of a glass portal and looking at the smoke from the pipes of neighboring houses, sparkling snow ... and you are in shorts and with aromatic coffee" ⠀
⠀
Large-format elements in glazing are a confident architectural trend in recent decades. “Windows on the floor”, “disappearing walls” and other constructions of this kind blur the boundaries between the house and the plot, fill the room with light and give a feeling of freedom and comfort. ⠀
⠀
💼 But so far not only ordinary consumers, but even professional architects and designers have some skepticism regarding large-format designs. ⠀
Skeptics believe that large forms are always large heat losses and insufficient safety. ⠀
⠀
Everything is completely wrong - proved by customers @energo_doma that we built houses with such structures and they never regretted it. ⠀
⠀
❗ Stereotype No. 1. Panoramic glazing - always large heat loss through the double-glazed window ⠀
⠀
Now even the largest large translucent design with a large number of opening flaps is able to provide heat transfer resistance comparable to a wall. ⠀
⠀
Such a design will work stably well and for a long time. The main thing is to understand that this is not “an ordinary dull window, only a large one”. This is a separate type of translucent structures, which works in a fundamentally different way and ALWAYS requires competent design. And in such designs you can not put simple double-glazed windows. ⠀
⠀
🌪 The design of the window should be designed for wind load taking into account the wind region, the installation height of the structure and the type of terrain (urban development, open terrain), the dimensions of the opening wings and the weight of the glass units used, and the requirements for heat and noise insulation. The design should be easy and convenient to operate, if necessary, provide special requirements for protection against hacking, child safety and protection against accidental loss. ⠀
⠀
If the solution is not professional, then it will not be possible to provide a comfortable microclimate in the room.

Panoramic glazing - stereotypes. ⠀
No. 1: Always large heat loss through the profile ⠀
⠀
🔒 No, heat loss through the profile will not be large if you choose it correctly. And it depends on the size of the structure. The design of the panoramic window can be made of various materials, as a rule, wood, aluminum and PVC profile. Each of these materials has its own characteristics that must be considered when designing ⠀
⠀
🔗 The PVC profile allows you to make the structure in a single frame: up to 8 m2 or, when using special facade profiles, a much larger area. The design must provide for temperature compensation joints.

The choice of material for panoramic glazing is made on the basis of technical and economic comparison, taking into account the design of the structure, color solutions.

The design with a width of 7.5 and a height of 2 floors will be optimally made of an aluminum profile.

Stereotype No. 2: Heating costs will increase
⠀
⠀ 📋 Properly designed panoramic windows do not significantly increase heating costs. For many of our customers to whom we installed “windows on the floor”, large-sized sliding elements, “disappearing walls” and other large-format structures, this was a pleasant surprise: ⠀
🗣 Customer:
Winter has passed and I see: HEAT RECEPTIONS from the sun far exceed losses. A room with a window for a day is so warm that it lasts all night. ⠀
🗣 Client2:
The portal costs the third year (this winter will be the third). I did not do any additional warming. No additional heating costs were noticed. ⠀
🗣 Client3:
The kitchen has two large windows, one of which is panoramic. But there are more advantages - if most of the windows are on the sunny side, this is a big saving on lighting and is very warm even in winter

Stereotype No. 3.⠀
Panoramic glazing is unsafe ⠀
⠀
Transparent structures that visually erase the boundaries of the house with the outside world seem vulnerable to outsiders. Like it or not, but glass is not concrete; throw a brick at him, and it crumbled. This worries many homeowners who dream of sliding glass walls. ⠀
⠀
⠀
💥 How can thieves act? I went to the fence, threw a stone, the glass fell out, come in and take what you want. And if the glass does not break, then it makes no sense to walk around and throw in all the windows. ⠀
⠀
😄 Actually, there is no reason for such concern: as our expert says, in panoramic glazing it is possible to use special glasses, which, with such an impact, can not be destroyed. ⠀
⠀
⠀
And a whole range of additional measures can strengthen protection: ⠀
⠀
- triplex ⠀
- film ⠀
- roller shutters ⠀
- alarm (with stickers on the fence that the house is guarded) ⠀
⠀
⠀
🗣 I have a hot eight and the film is standing, during installation I personally threw a brick - it normally holds. But I did this only for protection from small things, he usually walks with a hammer, and would have managed with a triplex. ⠀
⠀
⠀
Most of our customers who choose panoramic glazing consider such expensive solutions to be redundant, since in fact large-format constructions are attractive for attackers ⠀
no more than ordinary small windows. ⠀
⠀
Usually to protect large structures are limited to triplex. ⠀
⠀
⠀
⛏ In order to cut a hole in triplex 44.2, which is enough to penetrate the house, one must diligently wave the ax for about 10 minutes. During this time, the police outfit will even be able to ski on foot.

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. ⠀

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. ⠀
⠀

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. ⠀

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! ⠀

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. ⠀
