Installation of internal ventilation systems

1 AREA OF USE

1.1. The technological card was developed on a set of work on the installation of metal air ducts of internal ventilation systems in public areas.

On the basis of this technological map, technological maps can be developed on the device of metal air ducts of internal ventilation systems in office space, offices with various constructive solutions in relation to specific layout conditions. The technology card under consideration can be tied to a specific object and take into account the structural dimensions taken. At the same time, the schemes of production, work, labor costs, mechanization, materials, equipment, etc. are specified. All technological maps are developed on the working drawings of the project and regulate the means of technological support, the rules for the implementation of technological processes in the construction, reconstruction of buildings and structures, when equipped with engineering networks.

1.2. For binding or when developing technological maps, the following documents are needed as the source data:

- working drawings of the ventilation system;

- architectural and construction drawings and floor plans for buildings;

- construction standards and rules (SNiP, VNC, SP);

- Instructions, Standards, Factory Instructions and Technical Conditions (TU) for basic materials used (wires, cables, vent box, air ducts, reinforcement, etc.);

- single standards and rates for installation of ventilation in rooms (Yenir, GESN-2001);

- production rates of consumption of materials (NRRM);

- Progressive standards and rates, labor organization and labor processes, used in the installation of systems for ventilation of buildings and structures.

2. General provisions

2.1. The regulatory framework for the development of technological cards for ventilation is: SNiP, CH, SP, GESN-2001 Yenir, production rates of materials consumption, progressive local norms and rates, labor costs, the norms of consumption of material and technical resources.

2.2. The work of the work consistently performed when installing the supply system of ventilation, includes:

- collecting made parts of ventilation;

- installation of the ventilation system according to the design scheme;

- Complete operation of the ventilation system.

2.3. Ventilation - adjustable air exchange indoors serves mainly to create an air environment favorable for human health that meet the requirements of the technological process, the preservation of equipment and building structures of the building, storage of materials and products.

A person, depending on the kind of activity (energy costs), highlights heat in the ambient air (100 kcal / hour and more), water vapor (40-70 g / h) and carbon dioxide (23-45 l / h); Production processes may be accompanied by immeasurably large discharge of heat, water vapor, harmful vapors, gases and dust. As a result, the air in the room loses hygienic qualities favorable for well-being, health and human health.

Hygienic requirements for ventilation are reduced to maintaining certain meteorological conditions of air (temperature, humidity and mobility) and its purity.

The essence of ventilation is as follows: the trim air is mixed with the air of the room and as a result of the heat exchange or mass transfer occurring in the room, the specified air parameters are created.

Ventilation installation work should be performed, guided by the requirements of the following regulatory documents:

Individual tests of ventilation and air conditioning systems are allowed only after complete assembly and installation of ventilation equipment, installation of fencing of moving parts, checking the state of wiring, grounding and the correct power of the power supply.

Before starting a comprehensive test and adjustment of the ventilation and air conditioning system, you must make sure that there are no people in air conditioners and supply chambers, as well as remove all foreign objects and tools from air ducts, filters, cyclones.

If, in the production of preservation systems of ventilation and air conditioning systems, extraneous noises or vibration of equipment exceeding the permissible should be immediately discontinued.

After turning off the power supply of the ventilation equipment, it is impossible to fit and enter the air ducts, bunkers and shelters until the equipment stops.

After the end of the presets and adjustments, as well as during breaks (termination of work, lunch), ventilation equipment must be disconnected from the power supply.

The procedure for making the installation, a specific work project, should be such that the previous operation will completely eliminate the possibility of industrial danger when executing the following. Installation of ducts and parts of equipment of ventilation systems, air conditioning and cold supply should, as a rule, be made large blocks using lifting mechanisms.

Under the mounted elements there should be no people. You can not fix the suspended duct or block of air ducts for farms, overlap and other building structures in places not provided for by the work project.

Installation of air ducts from forests, lobes and sites should be made at least two workers.

Alignment of flange holes when connecting air ducts should be made only by mandrels. It is forbidden to check the coincidence of the holes connected by the flanges with your fingers.

To prevent rocking or spinning the raised air duct blocks, it is necessary to use deficule of the hemp rope.

Work on the installation of ventilation boxes is allowed to produce only a good tool. Wrench keys must accurately match the sizes of nuts and bolts, not to have knocked out on the edges and burrs on the handle. You should not pinch or clean the nuts with the key of large (compared to the head) size with the lining of metal plates between the edges of the nut and the key, as well as lengthen the wrench by attaching another key or pipe.

Workplaces and plots of work when installing in the dark should be covered. The illumination should be uniform, without blinding the lighting devices on the working. The production of works in unlit plases is not allowed.
