The modern blessings of civilization allowto equip the house at will, equipping the dwelling with all necessary items for comfortable living, including supply networks. Can I imagine a modern house without a ventilation system and air conditioning? Today, this seems unrealistic, but before, people were not aware of such benefits.
Обустройство вентиляционных ходов – это не просто the words. To such work it is necessary to approach with not less responsibility, than to designing of the house. Arrangement of the building as a whole - from laying the foundation to putting it into operation - is an important and important process.
On how well designedThe ventilation system depends on its further functioning. Every detail is important here. After all, assuming even a small error, the system may fail and, for example, instead of cold air, drive into the premises hot. The ventilation system consists of a number of elements that are interconnected by special parts and shaped products.
The main factor affecting performanceventilation system, - the correct design. The calculation of the area of air ducts and shaped products is necessary for the harmonious work of the entire system. Carrying out calculations is a time consuming and time consuming task. Although today, this process is easy to carry out using special formulas or whole computer programs.
The calculation of the area of air ducts and shaped products according to the formula is as follows:
Sc = L * 2.778 / V, where:
Having calculated the area of air ducts and shaped products, you can get a number, measured in cm2.
To calculate the indicator use:
Here S is the area, D is the diameter of the duct / pipe, A, B are the dimensions of the airways.
The design of the ventilation system has its ownsubtlety. Carrying out such work, it is important not to forget about the possible loss of pressure in the network during the continuous circulation of air. For this purpose, a special formula has been prepared showing the degree of pressure required for the normal operation of the network:
P = R * L + Ei * V2 * Y / 2, where:
To determine the required parameters and shapesproducts, and components of ventilation, it is necessary to have a mathematical skill to be able to use formulas to determine the area of ducts and other indicators required during the design of the ventilation system. To simplify the design process, engineers have been working for more than one year to improve special programs - calculators that are able to automatically calculate. A person is only required to enter manually the requested values for calculating the area of ducts and fittings, and the program will do the rest.
Independently calculate the values for the fastenersFittings are only available to a specialist engineer. Although even the professionals of their business rarely do without special tables with coefficients, symbols and permissible norms for the circulation of airflows. Without a formula for calculating the area of air ducts and fittings in this work is indispensable.
A simple person without knowledge of individualareas of engineering are not able to perform the difficult stages of computation. Therefore, when designing not only ventilation, but also any other communication system, start independent work only for the work you can do, and trust the rest to professionals if you need a house with well-functioning communication systems and an optimal microclimate in the room, regardless of the weather outside the window.
