Installation and installation of ventilation systems in the apartment and house. Prices, rates for the installation of ventilation systems

Design allows you to create an effective air exchange scheme in the house, and the installation of ventilation systems allows you to realize your plans. Therefore, both tasks must be carried out as carefully and professionally as possible. The company "Engineer" offers installation of all types of ventilation systems, created both on their own and on someone else's projects.

Installation of ventilation in a private house is a whole range of works, taking place in accordance with generally accepted stages. Installation standards are prescribed in SP 1.03.02-2020. By following them, you will ensure the required indoor climate without incurring additional costs. To eliminate all kinds of risks, contact the Engineer company. Here, not only will they install ventilation in a private house, but they will also deal with the issues of its design and commissioning. You can order this comprehensive service right now.

Ventilation installation: what to pay attention to

When installing ventilation equipment, the following conditions must be observed:

If any of these conditions is not met, it will be problematic to maintain the desired microclimate in an apartment or house. Overpayments, alterations, premature wear and tear of equipment, problems with the installation and operation of ventilation systems - these are the consequences of cooperation with an unreliable company.

Turnkey ventilation installation: stages of work

When installing any turnkey ventilation system, you will definitely need to perform the following work: Installation of ventilation equipment. This includes the whole range of technical equipment - from air ducts and fans to clamps and filters.

You can order the drafting and installation of ventilation in a private house from different contractors. But then an item on preparatory work will be added to the list above. At this stage, the building is examined, the available documentation is studied, and a work schedule is drawn up.

If the ventilation system in a private house is designed and installed by one organization, then there is no need for preparatory work. In this case, specialists already know all the features of the structure, communications and equipment used.

Features of installation of ventilation equipment

Installation of ventilation systems is carried out according to standard technological maps. The sequence of actions is as follows:

Depending on the characteristics of the structure and the goals set, it is possible to install ventilation of the following systems:

Design allows you to create an effective scheme air exchange in the house, and the installation of ventilation systems - to realize the plan. Therefore, both tasks must be carried out as carefully and professionally as possible. The company "Engineer" offers installation of all types of ventilation systems, created both according to their own and other people's projects.

WORK SCHEDULE: DRAFTING, APPROVAL

When designing indicates the approximate time required for the implementation of each stage of the assembly. The schedule specifies the deadlines as much as possible, builds the sequence of deliveries and installation of equipment and components.

PREPARATION OF PREMISES

Builders prepare sites for the location of equipment and air ducts: they provide convenient access and lighting, check supporting structures, channels, fasteners for compliance with the parameters specified in the project documentation. Sans", sans-serif; color: rgb(0, 0, 0);">Ducts are usually mounted on the ceiling and covered by a false ceiling. There are several basic types of air ducts:

  • Rigid air ducts made of galvanized steel sheet, fiberglass or aluminum layers with insulation. The most commonly used galvanized steel ducts have low frictional pressure losses and take up little space.
  • Flexible ducts, usually used to connect duct elements or distributors air located on the ceiling. In addition, with the help of flexible round ducts, fan coil units are connected to the ventilation network.

In order to properly install the duct system, you need to do several steps:

  • Determine the desired thickness sheet (the cross-section of the duct is already calculated during the design).
  • Calculate the lengths and weights of the duct sections for the correct placement of the fasteners.
  • Select the connection system for the duct sections.
  • Install duct system, respecting all the conditions of the project.
  • Connect the main duct to the fan.
  • Attach the ducts to the false ceiling.
  • Connect the air distribution elements in the rooms served by the air conditioning system and ventilation

There are several types of connecting metal duct sections. When available space is limited, it is best to use flat connections with a minimum projection height.
When connecting the duct to the fan, an anti-vibration pad should be placed between the fan outlet and the duct to prevent vibration being transmitted. In addition, it is important to eliminate any leaks in the connection that cause noise and uneven air distribution.
The method of fixing the duct to the ceiling depends on the size and weight of the duct. To do this, different fasteners are used.
If long flexible round air ducts are used in the system, it is important to fasten them correctly, avoiding sagging and changing the round section. The distance between adjacent fixing points should be no more than 3 m, and the maximum sag of the duct should not exceed 4% of the distance between fasteners. In order not to crush the air duct, it must be hung on cables or loops at least 25 mm wide.
The air duct can be connected to the air distribution grill in one of three ways:

  • by direct installation of a duct in the hole on the duct housing by a duct from the main duct with flow distribution over several ducts. At the same time, a round or rectangular hole must be made on the duct wall and an adapter connected with a flange, ending with a connection to the distribution grille.
  • using round flexible ducts. The flexible hose is attached to the flange on the main duct with a flexible clamp. The other end of the sleeve is connected to the grid with the same collar. At the same time, the hose should not have a bend of more than 90 degrees, so that there is no turbulence in the flow and increase in noise.

The reliability of the ventilation system depends on professional installation. Specialists are required to know the specifics and many subtleties of installation, they need special tools.


VENT EQUIPMENT INSTALLATION

Specialists check the equipment for compliance with the parameters stated in the project , and then proceed to the installation - they equip vibration-absorbing bases, install the equipment and connect it to the air ducts.

AUTOMATIC INSTALLATION

Automation significantly increases the price of ventilation installation. However, it performs a key task - it allows you to maintain the temperature and humidity of the air according to the specified parameters, monitors the operation of all nodes and reports the slightest malfunction.

COMMISSIONING

When everything installation work is completed, the system is launched and tested in various operating modes. Based on the results of the inspection and testing, certificates of acceptance of the facility are drawn up.

You can order a comprehensive service for the design, installation and commissioning of the ventilation system in Minsk at a reasonable price at the Engineer company.
