Major ventilation repair - polyclinic

Ventilation.

Common part.

The design solutions for the section "Ventilation" of the construction project for the reconstruction of the children's city polyclinic were developed on the basis of the tasks of related departments and existing technical regulatory legal acts.

The construction project provides for the creation of acceptable sanitary conditions for the air environment and the provision of technological requirements for health facilities, as well as administrative and household.

The ventilation heat consumption is:

Qvent. = 141275W.

Ventilation

Ventilation in the premises of the children's city polyclinic is designed inflow with mechanical and natural motivation.

Separate exhaust systems for: rooms - B1 system, showers and wardrobes - B2 system, washes - B3 system, all storerooms and warehouses - B4 system, temporary storage of waste - B5, s/u - B6; box insulators (intestinal) - B8 system; pool - B7, laboratories - B9 systems; B11; clinical - diagnostic, surgeon's office - B12 system; room for gasket processing - B13 system. Local suction from the exhaust cabinets is also provided in the laboratories. Air removed by exhaust systems is compensated by inflow from plenum units. Air to compensate for the exhaust from the rooms is supplied to the corridor, and for other rooms where air exchange is more than 1.5 kart, air is supplied directly to the rooms. Rooms with categories "h" and "d" are serviced by separate ventilation systems. In rooms where natural ventilation is required according to regulatory requirements, ventilation exhaust systems with natural motivation are provided.

Fans are connected to fans through vibration isolating flexible inserts made of material providing flexibility, density and durability. Vibration insulating flexible inserts shall be installed immediately prior to idling of ventilation equipment. Flexible inserts are provided in the project (see equipment specification). Radial fans located in the exhaust vent chamber are installed on spring vibration isolators, which must have a uniform draft. Vibration insulators do not need to be attached to the floor. The number of vibration isolators per fan is specified in the equipment specification.

It is also provided for ventilation of all the premises of the clinic through open framugs of windows.

Fire-retarding valves of KLOP1 type, which are blocked with fire alarm, are installed on air ducts crossing barriers with the established fire resistance limit. They must be installed directly in the barrier or outside it, providing on the section of the duct from the barrier to the valve a fire resistance limit equal to the fire resistance of the barrier. All transit air ducts through the floors pass in mines with a fire resistance rating of 0.75 hours. All ducts passing through the attic and having an exit to the street are covered with insulation material of the type "Paroc," which performs the functions of thermal protection and fire resistance.

A smoke removal system is designed from the basement corridor with a natural impulse through the ventshahta, in which a smoke ventilation valve is installed under the basement ceiling.

Outdoor air supply to staircases is not provided, on escape routes combustion products are removed through openings.

The height of the discharge from the roof level shall be at a distance of 1.52 m, the emission marks are indicated on the ventilation system diagrams. Umbrellas are installed on all air ducts to prevent precipitation from entering them. Emissions from fans installed in the exhaust ventilation chamber are collected in one shaft, which has a height from the roof level of 1 m. Check valves of KO type are installed on branches of air ducts to prevent overflow of air and smoke through air ducts when the fan is stopped.

All ventilation units in case of fire shall be switched off except for smoke removal valve.
