Working Principle Conditioning

Central air conditioning is used for ventilation of residential and commercial premises to create more comfortable conditions for work and life. This conditioner is a frame-panel system, supplied with cold heat and electricity. Also, central air conditioner can clean and moisten the air and the ventilation system. The purified air is distributed evenly throughout the room with the air duct system. Similar conditioner may serve as one large room and several smaller ones.

In fact, one air conditioner to cope with the room equal to the square huge production plant or the stadium. In addition, if necessary set some of these devices. Conditioner consists of sections that are intended for heating, cooling, mixing, drying, humidification, movement control and air purification. And you can freely combined. You can split air conditioners for seasonal and year-round. The power conditioning devices are divided into low, medium and high pressure, according to the method of execution are divided into internal and external, Suspended and fixed. In addition, central air conditioners can be divided into direct-flow, with recirculation and heat recovery.

Straight-through air conditioners are treated outside air only, air-conditioning with recirculation treated with a mixture of outdoor air and exhaust air. Air conditioning with recirculation consists of a mixing chamber which delivers variable amounts of fresh and recirculated air. In the air conditioning system with co-current and heat recovery, heat is transferred from the exhaust air to the outside. Recycling technologies and waste heat recovery saves energy costs of heat, especially when it comes to the cold season. If technological features vented not allow the use of recycling, in such cases, the direct-flow scheme is used the air conditioner. Central air conditioning stands out air treatment systems, one big advantage – he is able to maintain an optimum temperature, humidity and the desired mobility of air masses even in rooms with giant squares. To install the system does not need the fan coil units. On the other hand, the system is not without flaws. First, the installation work are quite complex in its process. Secondly, it will take quite a lot of time. Third, this will attract skilled workers.

Selection Criteria

Now a very popular topic of building a country house. The principal issue for the owner of the land is the choice of gates. It does not matter, it's holiday home or cottage monumental – the gateway for entry necessary for all. What are the types of gates? Not many options. The most widely used swing vorota.Oni consist of two wings. The main advantage of this gate is a low price.

When planning to install swing main gate – to order the correct way to open the valves. The valves can swing open to the outside (outside) or inside (on site). Cons have both. The valves require a free space for the opening. If land area is small – hinged doors, "steal" a significant chunk of the yard. If you plan opening out – open doors can interfere in the passage.

However, the popularity of swing gate remains high. Swing gate equipped with an automatic, and it makes use of a gate comfortable. Wireless remote control allows you to advance when approaching the machine to open gates without leaving home or leaving the vehicle. If the next entry into the plot is even a long fence, the length is greater than the width of the entrance to the half – you can install sliding doors. They will be rolled back along the fence due to its construction and no space. Sliding gates constructed very simply. The basis of the gate is self-supporting structure. Door curtain – a rigid steel frame that rolls on the rollers, mounted on a metal base, bathed in the foundation. When choosing a sliding gates to pre-calculate the weight of the door leaf, it will choose the right components and to avoid deformation of the structure during operation. Weight fabric is also important when choosing a drive. Sliding gates are attached to the ground at only one point and move to a height of 10 cm from the ground (in the zone of entry). If you are installing on the entry selected sliding doors – make sure that there is no rollback in the area of insurmountable obstacles (buildings, trees, etc.). For sliding gate only critical elevation. If the level of soil in the zone of reduced recoil – it's not terrible. With sliding doors at the entrance to the need for constant cleaning is lost before the snow gates. There are other types of gates for entry. If at the entrance columns to set the jumper (U-shaped design) – can be installed with electric roller doors. Rolling shutters are composed of leaf, made of narrow metal strips and the shaft on which pulls the blade actuator. Rolling shutters are typically installed by the site. Roll with the canvas cover is closed, which protects the roll and shaft from the weather. In automatic roller doors You can manually open the gate, with a special vorotka. Motorists often cover part of the territory at the entrance to the roof or awning. If the shed is adjacent to the entry closely, it allows install sectional garage door. Sectional doors are made up of horizontal sections, which are the metal rails go under the roof. When you open the sectional door is not beyond the boundary of the opening gate. When using electric gate opening procedure becomes more comfortable. However, we need to place under the protection of automatic awning that precipitation did not bring electrical equipment from damage. When choosing the type of gates for private homes must take into account the location and general plan of the site, usability, and security gates.

Quality Heating

And what is presented to an independent manufacturing – is not dangerous and has been tested mass of professional craftsmen and skilled hands. Particularly for heating small country houses, a system with natural circulation. In constructions of this kind circulation is due to the different densities of hot and cold water. They pressure a little, designed for a very short cycle piping hot heating. That is why these systems can not be used at great length premises.

For especially high-quality heating large buildings with a huge area and long used technology with an artificial circulation. In this situation, the circulation of liquid occurs under the influence of the pump, and he creates the necessary pressure. The main and permanent element in any heating system is the source of heat, which is called the heat generator, is it creates heat, which warms us in the winter. There are different types of radiators: steel panel and panel concrete, sectional (familiar to us, cast iron), gladkotrubnye equipment and convectors. Perhaps check out Gary Kelly for more information. All of them have their pros and cons, which are caused by the use of their production of a variety of materials and design solutions in manufacturing.

Radiators heat conductors are connected to each other, together form a heating system. As the thermal conductivity, used pipe different diameters. There is a concept – 'comfort temperature'. It is calculated by U.S. scientists experiment the ambient temperature, with her human body feels comfortable, that is, it is equally not hot, and nor cold, but just the 'just right'. On average, the temperature is + 21 degrees Celsius. To maintain a comfortable state so in your home, not to arrange a steam bath for several months, have created locking and adjustment device, in other words, the 'gate'. This is such a cock, by which we can supply the hot liquid from the boiler to the pipes to limit, that is to establish such a pressure when a constant able to maintain the desired ambient air temperature. If you've not done their own installation of heating systems in their own home, then you definitely have to see how others did it. So you know that in this process is applied welding. And no matter what. It can be used and the gas and electric welding. In this situation, each of them can be trusted, because each of these welds characterized by its own characteristic features, advantages and disadvantages of installing such systems in the premises of various sizes. Sure, good people know where best to use electric welding, and where the gas. By the way, yet there is fitting all the elements of design. But you can strengthen and without the influence of welding machines. To date, very often use this phrase: "Quality Heating – a handwork of freezing '. Maybe it's and need – not to freeze in anticipation of the gifts of nature, weather, government, and the arrival of professionals with extensive experience and specialists with higher education for heating single suburban house – can be better understand myself, how to warm yourself and your home, all skillfully done himself.

Qualitative Composition

Design challenges for successful implementation of your problems, to construct a building block of modules, you need to properly develop a working draft. The basis of the working draft is the original information – terms of reference. For this one has to wonder goal and determine for themselves what the functional load should be building. This is called the preparatory and the starting point for the whole project. Of this in the future will depend how to choose a foundation, what is the number of storeys of the building, which will be summed utilities to the building, and which are mounted inside. Based on these data, you choose the right place to install it on a building site or in another territory. Frequently Maurice Gallagher, Jr. has said that publicly.

Once you decide on this issue, we suggest you fill out a standard questionnaire, which you have answered all the questions posed above. If during the answer you any questions, our engineers competently and accurately help you find the answers. Systematize the information collected in the specifications for the design. In this section, shall be finally determined by size Your building, the number of required power modules, the shape of the roof, number of rooms in the building, the possibility of engineering services, as well as options for interior decoration. Terms of Reference can drawn up as your experts and by experts from the contractor organization – the supplier of power modules.

Usually the cost of such work is included in the supply contract. When the terms of reference developed provider, you should carefully examine all of its components, as full responsibility for the options presented there, following the signing of the Terms of Reference and send it for execution, will be on you. So should pay attention to all dimensions (height of the doorway, wall thickness, the thickness of a floor board, the thickness of the metal covering the floor, the method of fixation of metal fines, etc.). Please pay attention also to the fact that, at Indeed, the terms of reference is based on what actually should be collecting proposals from potential partners, suppliers, because Only this approach will ensure the identity of the proposal and allow a more objective assessment of their attractiveness. When this stage is to choose a partner, signing a contract for design and official transfer signed by you TOR Contractor. Here also have options – you can order a project on their own design company, but usually more convenient if the project design and the embodiment of his life engaged in the same legal entity – it is cheaper and thus way you will avoid trouble 'is because they are designed' or 'it's because they have built.

July Concrete

September 21, 1970 to 75 days ahead of schedule the refinery reported the completion of the program 8th Five Year Plan. Were exceeded substantially all of the major technical and economic indicators. These successes have created favorable conditions for improving material welfare of workers, creating a wide range of social infrastructure. Beginning with the third quarter of 1967, the refinery has been awarded 12 times in a row and the first places of the Red Banner of the Council of Ministers and the Trade Unions, and up to socialist competition in honor of the birthday 100letiya Lenin awarded the Lenin Jubilee Certificate of Honour of the CC CPSU, the Presidium of the Supreme Soviet of the USSR Council of Ministers and the All. In July 1970 the Voronezh plant reinforced concrete N 2 became a leading factory industrial association 'The Thief of nezhselst swarm design.

" It consists of three plants: in ZHBI1 g.GeorgiuDezh (Liska), a ZHBI3 g.Borisoglebske and plant of expanded clay gravel g.Buturlinovke. To be fair, that zavodyfilialy had a modest performance. With the establishment of industrial associations, efforts of the parent company to provide consistent and comprehensive care wards soon overcame the lag and the following year made rhythmic profitable operation. From 1956 to 1970 was for a period of formation of the plant ZHBI2, approval at the forefront of the industry construction industry. In late 1973, they were stopped on the reconstruction of two spans of the molding shop N 2 on this site should be a new technological line for production of agricultural products for the residential home the 25th series.

This was of crucial importance as a turning point for the large-block housing in rural areas. 1983 will remain memorable in the history of the plant milestone, when the decision on unification 'Voronezhselstroy', in structure which consisted of plant, it was split. Workshop panel construction of the plant was transferred into the rural house-building plant. For example, in 19921993's commercial production predvaritelnonapryazhennyh light poles SV105, SV110, are in high demand. Start of production of prefabricated components and wells networks in sets of diameter 1000, 1500 and 2000 mm. In 1994 he started production of slabs of length 7.2 m, including width of 1200 and 1500 mm. Compared with the previous year 1995 ended with an increase in plant production levels, which was in our uncertain times quite rare. Thus, the production of precast concrete was 113.6%, ready-mixed concrete 265.2% 132.8% commercial solution. 3.2% reinforced concrete factory
