Требования к помещениям венткамер

Key Standards:

SP 118.13330-2012 Public Buildings and Structures;

SP 51.13330.2011 Noise Protection;

SP 60.13330.2020 Heating, Ventilation, and Air Conditioning

Placement of Ventilation Chambers:

4.15 Ventilation chambers, elevator shafts and machine rooms, pump rooms, refrigeration machine rooms, heating units, and other rooms containing equipment that generates noise and vibration should generally not be located adjacent to, above, or below auditoriums, rehearsal halls, stages, sound equipment rooms, reading rooms, patient rooms, doctors' offices, operating rooms, rooms where children are accommodated in childcare facilities, classrooms, workrooms, and offices with permanent occupancy, or residential premises located in public buildings. Adjacent placement, as well as placement above and below the specified rooms, is permitted provided that the standard sound pressure and vibration levels are ensured, which must be confirmed by calculations according to SP 51.13330 and comply with SN 2.2.4/2.1.8.562, SN 2.2.4/2.1.8.583, SN 2.2.4/2.1.8.566.

11.21 To prevent the penetration of increased noise from HVAC equipment into other rooms of the building, the following should be done:

avoid placing rooms requiring increased noise protection (operating rooms, hospital wards) adjacent (horizontally and vertically) to technical rooms containing equipment (ventilation chambers, pump rooms, refrigeration centers);

vibration isolation of the units using spring, rubber, or combined vibration isolators;

Carry out acoustic treatment of technical rooms (rooms containing equipment) - cladding walls and ceilings with a layer of ZPM (if additional noise reduction in the room by 4-7 dB is required);

Use floors on an elastic base (floating floors) or vibration-damping bases under system components (fans, air conditioners, refrigeration units, air coolers, pumps, etc.) in technical rooms;

Use enclosing structures for technical rooms containing equipment that provide the required airborne noise insulation, determined by calculation;

Install flexible inserts between fans and air ducts.

In rooms containing equipment (ventilation chambers, pump rooms, and refrigeration centers) located adjacent (horizontally and vertically) to residential and office spaces, acoustic treatment should be provided, floors on a resilient base (floating floors) should be used, and vibration isolation of the equipment should be provided. In these cases, fastening equipment and pipelines to common enclosing structures between technical rooms containing equipment and residential and office spaces is not permitted.

Dimensions of ventilation chambers:

10.12. Building structures for rooms housing heating, ventilation, and refrigeration equipment should be designed to accommodate the use of lifting mechanisms, in accordance with 10.7. The height of the rooms from the finished floor level to the bottom of protruding floor structures is set by the design specification at no less than 2.2 m. In rooms and on work platforms, the width of the passage between protruding parts of the equipment, as well as between the equipment and building structures, should be designed to accommodate installation and repair work, but should not be less than 0.7 m. The distance between equipment should be designed to allow for the dismantling and subsequent installation of individual components of the equipment with maximum dimensions.

Floating Floor and Vibration-Isolating Base:

11.21 To prevent excessive noise from HVAC equipment from penetrating into other areas of the building, the following should be done:

isolate the units with spring, rubber, or combined vibration isolators;

acoustically treat technical rooms (rooms containing equipment) by lining the walls and ceilings with a layer of ZPM (if additional noise reduction in the room by 4-7 dB is required);

Use resilient floors (floating floors) or vibration-damping foundations for system components (fans, air conditioners, refrigeration units, air coolers, pumps, etc.) in technical rooms.

Use enclosing structures for technical rooms containing equipment that provide the required airborne noise insulation, as determined by calculation.

Install flexible connectors between fans and air ducts.

In rooms containing equipment (ventilation chambers, pump rooms, and cooling centers) located adjacent (horizontally and vertically) to residential and office spaces, acoustic treatment should be performed, floors on a resilient foundation (floating floors) should be used, and vibration isolation for the equipment should be provided. Fastening equipment and pipelines to common enclosing structures between technical rooms containing equipment and residential and office spaces is not permitted in these cases.

Foundations:

Regulations do not require the use of concrete foundations for ventilation equipment.

The units are typically supplied on their own frame, so they can be installed directly on the prepared floor of the ventilation chamber.
