Heating Design

The architectural design of private homes focusing on the design of the heating system. Properly design and install heating system will help professionals who specialize in this area. They help you select the project, it is suitable for your home. Since the design of heating systems can be divided into several stages. First, determine the type of coolant circulation. Circulation is a natural and enforced.

In the natural circulation pump is not used, which means that this type of circulation has a certain independence from the electricity. But at the same time by using the heating system with natural circulation has drawbacks: large diameter pipelines, adherence slope, there are difficulties in adjusting the heat, the inability to control some elements of the system. If there are no forced circulation problems, but it strongly depends on the source of energy. The landlord must, at the initial stage of design to choose the type of circulation, because this will depend on the range of devices, appliances and heating units. Second, during the design of the premises is necessary to provide openings in the walls, the floor that will be needed for the distribution of heating collectors, sewerage and water supply: country house heating, heating in the cottage.

Technological holes will hide all the elements of engineering systems at the same time provide access to them for maintenance and repair work without disrupting the design space. Third, choose a location for the boiler house and build a channel for the chimney. In addition to the chimney brickwork should pave the steel pipe to protect the brick from the condensate, which can occur when large temperature differences during the winter. Fourth, determine the number of sections of the radiator. To do this, calculate the number of square meters, which can warm up one section. The formula is simple: heat one section must be divided by 100. For example, calculate how many radiator sections you need for rooms of 16 m2. Determine how many meters obogreet one section of the radiator. To do this, heat equal to 199 divided by 100 Tues, the result is about 2 m?. Therefore for rooms of 16 m2 will take eight sections. If the room is a balcony or a room in the house corner, you will need to increase the number of partitions in two or three.

Technical Data Sheet

Typically, our customers to buy a shower, we will send by fax or e-mail, wiring diagram, this is his chosen kabiny.Delaetsya to prepare in advance the necessary conclusions and to avoid possible alterations. Installing a shower is in a room specially prepared for this, in strict compliance with these recommendations. WARNING! When preparing water for Communications connect the equipment you must install a mechanical water filters, with the degree of purification of 100 md. The water pressure in the water system should be in the range from 1.5 to 5 atm. In case of excess pressure you must install a pressure reducer water. Filters, RCD, pressure reducing water as standard equipment are not included.

Conclusions hot and cold water must have an internal thread and diameter. inches. Diameter sewer pipe 40 -50 mm.Esli conclusion sewage into the wall, the distance from finished floor to the center of the pipe must not exceed 50 mm. If the distance is longer, you have to do poddium. Poddium under the shower in the strict Order must be lined with tiles.

Connect the equipment to the mains must be performed without additional compounds, ie a separate cable from the electrical panel to the equipment. Cable should be copper, three-core, double insulation with a wire cross-section of 2.5 mm square. The output electric cable must be located in a place designated in the Technical Data Sheet and have a grounded receptacle. The cable must be connected to separate, two-pole machine, combined with the current device (RCD). The requirements for RCD: 220V – 240V, with leakage current 0.03 A, 16-25A. For the installation and subsequent maintenance of equipment need space for two rear sides of the cab not less than 50 cm, to provide access to all work sites and aggregates. The ceiling height in the room, prepared to install a shower enclosure should provide clearance between the roof and ceiling shower for at least 10-15 cm in maximum allowable temperature using acrylic shower stalls shall not exceed 60 degrees Celsius. Area for mounting a shower should be cleared of debris and various contaminants. All repairs and finishing work during installation must be necessarily completed, including finishing the ceiling. All communications should be hidden pad, or be removed in the decorative door. This will help avoid gapping product to the wall. Area for the installation should have no protrusions and borders. I hope this article will help you avoid errors and defects, which are sometimes faced by our clients.

Regulation

Thus, when tamping the way two people can shpalopodboykami to work with 2.4 or 6 jacks. Rams set to shpalnye boxes in pairs under each rail through 8 … 10 boxes. In the course of the rear pair of jacks consistently rearranged in 8 … 10 shpalnyh boxes next to the front of work (Detail the technology of production of various types of track works, using jacks and other MPI, including hydraulic, described in the applicable legislation, such as instructions for the current maintenance of railway track. – Moscow: Transport, 2000 1 Regulation and implementation of the basic technology works with the current contents of the path.

– Moscow: Transport, 1998. 2). Rihtovschiki with manual transmission and the executive motor rihtovschikov placed near the rail (the side opposite to the direction of the desired slight shift) so that the double-hinged arm and shovel were placed under his soles. If the surface of the ballast is contained in a good state, then the installation is not required to align rihtovschika ballast and remove it from the rail in shpalnom box. The executive bodies of both manual and motorized rihtovschikov set at an optimal angle to the horizon (defined almost as a function of the track panel weight, degree of compaction of ballast, the quantities required Sdvizhkov way, the number used in set viewed by rihtovschikov, etc.), so that does not support slip in ballast and not unduly raised her path (25 mm).

SVC Equipment

Stalagmometr ST-2 is designed to determine the surface tension of surfactant solutions by determining the amount of drops is squeezed out at the borders: the solution – SAW antipolyarnaya liquid or solution – SAS – air. Stalagmometriya – method of separation of drops is common in medical and pharmaceutical practice. The theoretical justification of this method is as follows. Formation of drops of liquid at flowing out of her small holes is the result of surface tension and gravity. For example, if the set of vertical tubes with a narrow capillary bore liquid seeping slowly, then at the end of the tube is formed slowly increasing in size drop. Increasing in size, the drop off when its weight becomes equal to the resistance to rupture the surface film, which supports the drop. Before the separation of drops at the end of the tube is formed constriction at which separation occurs drops.

Stalagmometr a glass tube with an extension of the middle and the bottom of the capillary, the extended portion is bounded by two marks. Put the tube in a beaker with test solution, using a rubber bulb delaying a solution to the instrument (the fluid level should be above the upper mark) and give a liquid drop by drop flow from stalagmometra in the cup. The exhaust velocity can be adjusted using a screw clamp. When the liquid level reaches the upper mark, start counting drops, counting continues until the bottom level of the label. Stalagmometr ST-2 is designed to determine surface tension of surfactant solutions by determining the amount of drops is squeezed out at the borders: the solution – SAS – antipolyarnaya liquid or surfactant solution – air.
