Low Humidity

Humidification has a special role in providing comfortable climatic conditions in winter when, even at high relative humidity of air, its absolute water content is as generally very low. Proceeding to the room air is heated. Moreover, its absolute water content remains unchanged, and the relative humidity drops to 5-10%. For comparison, the relative humidity in the Sahara Desert did not fall below 15%! In order to maintain relative humidity at a comfortable level of 50% at room temperature 20 C is required artificial humidification, often enough intensive. In addition to providing comfort, maintaining the necessary level of humidity is also extremely important from the hygienic point of view. It is known that the bacterial flora (pneumococcus, staphylococcus, streptococcus) inhibited 20-fold intensively at a relative humidity of 45 to 55% than when humidity is above 70% and below 20%. Today humidifiers are divided into: steam (cold or hot steam) and ultrasound. The most simple form are humidifiers with a cold vapor.

In a special compartment filled with water that soaks into the cassette. Through this cassette is a normal room air, blown by fans humidifier. To achieve maximum the effect of such humidifiers should be placed near a heat source (eg, sink). The advantage of these models is the efficiency in electricity consumption, ease of use, quiet operation and Low price. The disadvantage is that these moisturizers will not do "rusty" water from the tap, but if you're still on a dare, you have to buy a special filter. Also, humidity control will depend not on your desire, but from the room air.

Humidifiers with hot steam, respectively, have a number of design features. In them, as in a normal kettle, the formation of steam from water by boiling it. This device itself will maintain the necessary humidity in the room, except when it is over water – itself off. This type of humidifier has a function, so to speak, family doctor. That is, can used for inhalation of air in the house, and hot steam is already kill all microbes. The drawback, steam humidifiers is perhaps only by their high power consumption, water consumption a little more than cold-steam humidifiers. The latest and most advanced type of humidifiers – ultrasonic humidifiers. Through high-frequency sound vibrations from the water a cloud of cold vapor. Air passing through a cloud, saturate with moisture, and the instrument adjusts the level (ie, humidity), depending on your desire in the range of 25-85%. The price of these humidifiers are much higher than that of steam, about 1,5-2 times. This Article courtesy of Air Alter () for the dissemination and popularization of our site.

Chimney Installation

Such details are: pipes, tubes with revision, tees, elbows, deflectors. They connect with each other due to the exact size and fitting secured with clamps. With this method of connection setup chimneys can made after the building in a short time. You can assemble any desired configuration chimney due to a large range of fittings. Here, Vislink Technologies expresses very clear opinions on the subject. The modular principle of installation provides the convenience, speed and cost jobs. Munear Ashton Kouzbari may not feel the same. Importantly, the modular chimney at any time be subjected to demolition. Consider these question on the example of installing a two-chimney system.

Installation of two-circuit chimney should start from the bottom (of the heating system) up. When installing the inner tube further element must be a member inside the tube of the previous item. This is to ensure that emerging condensate or falling into the chimney precipitation remained inside the chimney and did not fall on the heater. The outer tube (shell is), in turn, puts the previous one. Pipes should sit down with each other at a depth of planting, which should not be less than half the diameter of the pipe: a requirement of fire safety regulations. Depending on the design elements of a particular manufacturer, place of docking can condense or relevant clamps, or due to taper pipes.

For better sealing of pipes is desirable to use the sealant with an operating temperature of at least 1000 degrees. The joints of pipes with other elements of (tees, elbows, etc.) should be fastened together with clamps. For every two-meter chimney must be installed mounting bracket to the wall, and the tee should have the support bracket.


Warm floors – one of the solutions to create coziness and comfort in a house or apartment. With the help of warm floors to solve the problem of both the main and auxiliary heating. The latest version of underfloor heating are more effective solution than, for example, heaters. One option for floor heating is Metafields – the usual pipe mounted to the heating system or the pipes with hot water. Disadvantages: If there is dependence on a central system heating – the inability to control the temperature in the underfloor heating and a possible lack of pressure in the system for pumping pipes. There is also a real risk of damaging the battery during installation or during operation that will lead to overlapping of the riser. From the above we can conclude that Metafields more practical to use in your own home (country cottage).

Another variant of the floor heating – heating electric cable. This system can be used at any time of year, the floor temperature is regulated by termolegulyatora. It is possible to program the system to cycle. The security of this system ensures that breaker in case of disruptions in supply. Disadvantages: fast heating flooring leads to deformation thereof. Increased power consumption. Before you begin installation of underfloor heating, you need to remove the old floor and level the surface, do screed. The prepared surface is laid a layer of insulation. You may find baby clothes to be a useful source of information.

As the heat insulation of floor heating, you can choose polipenouretan or folgaizol. Placed on top tube (Usually the diameter is 20 mm) or electrical cable. The distance between the pipes and cables – 150-200 mm. All this is poured concrete with thickness of 30-50 mm. Now we must decide which floor to choose. If as a floor covering use parquet, in this case it is worth considering some of its features. The temperature of a warm floor when used as flooring lacquered flooring must not exceed 21 degrees.

Electrical House

The easiest way cable – open. The price for such work will be the lowest with all the options listed in this article – as prices for electricity themselves assembly work, and estimates for consumables. But remember that the wiring open for combustible construction – is prohibited. This kind of wiring is suitable for concrete, masonry walls in production, basements, storage rooms. Becoming popular is another way to hold the light in your house – it's kind of old electrical wiring in the roller centers.

The people he called the wiring under the old, in retro. Different original design, circumferential nostalgic about the past. Solid electrical stranded wire laid along the walls and ceilings on insulators with distance from the surface, so that it complies with fire bezopasnosti. electrical wiring in a wooden house. Concealed wiring – padded inside the structural elements of buildings and constructions (walls, floors, foundations, overlap), as well as overlaps in the preparation of the floor, directly under the removable floor.

Electrical wiring is hidden at home, cottage, apartment, office, warehouse running in pipes, flexible metal hoses, ducts, closed channels and cavities of building structures in the render over the furrows, under plaster, as well as zamonolichivaniem in constructions in their manufacture. Hidden inside the electrical wiring in wooden house, the cottage is the subject of heightened danger. But despite this in any home from round, chopped logs, glued, shaped beam can be internal wiring, with must strictly comply with all fire safety requirements. Electrical installations in such buildings it laborious and expensive.

Implement Construction

If you decide to make repairs in an apartment or house and live in a big city such as Moscow, you probably encounter a problem shopping, delivery and selection of building and finishing material. Because it is very not easy to figure out how to offer the broadest assortment of repair materials, and a huge number of firms, what they offer. How to start a repair – first need to acquire different glue, cement, dry mixture, including possible use in addition walling and roofing materials. A little later, will need to buy finishing materials for walls, ceilings and floors, for example, linoleum, laminate or parquet floor, ceramic tile, wallpaper for walls. Also do not forget that all construction and finishing materials to be delivered. There are two options for further developments. First choice: self-purchase and repair finishing materials, you'll have to go to dozens of organizations, which have to pay not only material, but also supply each of its kind. Second option: use the services of integrated logistics and supply construction and repair materials necessary to you address..

Investigations At Sites Draining

Hydrogeological work and geotechnical testing when shooting are conducted to the extent necessary to justify the reclamation activities and the building structure reclamation system. The total area shooting must be grounded in technical regulations or program of research. Allowed to increase the area of photography compared to the reclaimed area of the object is not more than 1,8 times. It is mandatory to hold Preliminary desk work to assess the materials research of past years, area of study with the objective of the program or technical requirements. Geotechnical and hydrogeological research and studies on the drainage facilities are conducted to determine the causes of waterlogging and temporary excessive moisture, type of water supply in order to select the design decisions on how to drainage area and regulation of water regime. To justify the design solutions for land-reclamation should be examined following the main features of the object: – geomorphology (the structure of floodplains, terraces, valleys, basins, troughs drain; shape and area ratio of low and elevated stations, communications excess moisture from the morphological characteristics of the microrelief, the impact of micro-and macrorelief on waterlogging areas); – geotechnical (lithology and physical and mechanical properties of soils, especially nutrients (peat, sapropel)); – the nature and distribution of geological and engineering-geological processes – hydrological (availability, distribution and depth of aquifers, the hydraulic connection between them and among themselves and with surface water, balance and groundwater regime, their chemical composition, the amplitude of the fluctuations in groundwater level).

Field work must begin with a reconnaissance survey, during which identifies wetlands and redundant, wetlands, examined outcrops, landslide areas, distribution of karst, subsidence and other phenomena, the outputs of groundwater, ravines, etc. Block observations are carried out in two perpendicular directions, taking into account Stretch the major forms of relief, as well as along the river beds, lake and other natural drainage elements. In the process of engineering-geological survey should establish morphogenetic type of relief to which timed swampy land (slope, valleys, plains, etc.), identify the hazardous geological processes. If there are bailing on the territory of the ground-pressure power allowed additional exploration work, the composition and volume of which is justified in each case the program works (technical requirements). Cross-sections perpendicular to the wells should be scheduled during the main geomorphological elements – from the elevated grades (slopes, terraces, etc.) to the receiving water (river, marsh, lake) – a position of extreme well drained outside of the array on the slopes or local watersheds.

The distance between cross-sections should be taken from 500 to 700 m. Well on the alignment should be located at a distance of 300 to 500 meters depending on the geomorphological and geological and hydrogeological conditions. Other distances should be justified in the program or report on research. In the presence of at drainage systems, heavy soils underlain by impermeable, the wells should be drilled on the wing at a depth of 5 m. The number of additional wells in the complex engineering and hydrogeological survey shall not exceed 1.8 observation points (workings) of 1 km2 array drainage for pre-design study, and 2.7 points per 1 km2 array drainage for architectural and construction projects. Well depth is taken as a function of depth aquitard and its power. In case of a pressurized part of the supply wells (40% of the total) should be opened on the roof of the second surface of the aquifer. Depth of the wells should not exceed 35 m.
