Basic rules for designing ventilation

In modern conditions, the design of ventilation is a number of different works., requires precise engineering calculations and careful study of all details. This places special demands on the experience and professionalism of the design organization., her ability to solve complex problems and offer optimal, technically and economically sound solutions.

Mistakes in calculations can lead to all sorts of problems.. One of the most serious ones is the creation of a non -symmetrical and not subject to adjusting the network and the impossibility of eliminating harmful substances. Homemade ventilation systems are not always subject to adjustment and, often, require almost complete replacement.. That is why the design of ventilation is a complex and painstaking work., on which the quality and efficiency of the system depend.

It should be remembered that, that ventilation is created according to the requirements of a particular customer and based on the data provided by him. For this, drawing documentation of the building and terms of reference are required., prepared by the customer.

The ventilation design itself is divided into several stages:

• Preparation of data for calculating the load on ventilation equipment for each of the premises. To do this, the calculation parameters for indoor and outdoor air are selected., the amount of heat is determined, moisture and harmful gases, the scheme of organization of air exchange is selected.
• Construction of air treatment processes for design modes - cold load is determined, by heat to local units, etc.. d.
• Selection of the main equipment for ventilation and air conditioning.
• Development of the duct system, their aerodynamic calculation.
• Development of a functional diagram of automatic control of the ventilation system.

During the design process, a number of issues must be resolved, in t. h. Checking the compliance of the system developed by the existing requirements for noise and vibration. According to the results of the work, the customer offers several main solutions, from which he can choose the most suitable in terms of technical and economic indicators.

The basis for the design of ventilation are typical room layouts, normative documents, as well as the specific requirements of the customer and the features of a particular object. The final goal of design is to create a system, which not only provides the necessary air exchange, but also meets all regulatory requirements (fire safety, design, efficiency, etc.. e in.), is the most reliable solution for specific operating conditions and customer requirements.
