Ventilation SP 7.13130.2009 (not valid) Heating, ventilation and air conditioning. Fire protection requirements 6.58 Air ducts made of non-combustible materials should be provided: a) for local suction systems of explosive and fire-hazardous mixtures, emergency and transporting air with a temperature of 80 ° C and above; b) for duct sections with standardized fire resistance limits; c) for transit areas or collectors of ventilation systems, residential, public, administrative and industrial buildings; d) for installation within the premises for ventilation equipment, as well as in technical floors, attics, basements and underground. 6.61 Transit air ducts and collectors of systems of any purpose within one fire compartment may be designed: a) from combustible G1 materials (except for smoke ventilation systems) provided that each duct is installed in a separate shaft, casing or sleeve made of non-combustible materials with a fire resistance limit of E1 30; b) made of non-combustible materials with a fire resistance limit below the normalized, but not less than EI 15 provided that transit ducts and collectors (except for ducts and collectors for industrial premises of categories A and B, as well as for warehouses of categories A, B, B1, B2) are laid in common shafts with enclosing structures having a fire resistance limit of at least EI 45, and fire-fighting normally open valves are installed on each duct intersecting the enclosing ones. mine structures; c) made of non-combustible materials with a fire resistance limit below the norm, providing for the installation of transit ducts (except for premises and warehouses of categories A, B, warehouses of categories B1, B2, as well as residential premises) installation of fire-fighting normally open valves when air ducts cross each fire barrier with a normalized fire resistance limit. The fire resistance limit of air ducts and collectors (except transit ones) laid in spaces for ventilation equipment, as well as air ducts and collectors laid outside the building, is not standardized. (excluded) Smoke-free ventilation Clause 7.1 of SP 7.13130.2013 supply smoke ventilation systems should be used only in the necessary combination with exhaust smoke ventilation systems. The separate use of supply smoke ventilation systems without the installation of appropriate exhaust smoke ventilation systems is not allowed. According to clause 8.5 of SP 7.13130.2013 (current), for natural ventilation of the corridor in case of fire, it is necessary to provide openable window or other openings in the exterior fences with an upper edge located at least 2.5 m from floor level and a width of at least 1.6 m for every 30 m of the corridor length. Dormer (roof) windows that open in case of fire can be used to remove smoke. 7.6 Exhaust smoke ventilation systems designed to protect corridors should be designed separately from systems designed to protect rooms. The installation of common systems for the protection of premises of various functional fire hazards is not allowed.    8.8. To compensate for the volume of gorenje products removed from rooms protected by exhaust smoke ventilation, supply smoke ventilation systems with natural or mechanical motivation must be provided. Openings in the exterior fences or shafts with valves equipped with automatically and remotely controlled actuators can be made for natural air flow into the protected rooms. Openings should be in the lower part of the protected rooms. The vestibules of the valves must be equipped with means to prevent freezing in the cold season. The doorways of the exterior escape exits can be used to compensate for the influx of outside air into the lower part of the atriums or passages. The doors of such exits should be equipped with automatically and remotely controlled forced opening drives. The total cross-sectional area of the doors to be opened must be determined in accordance with the requirements of paragraph 7.4 and under the condition that the air flow velocity in the doorways does not exceed 6 m/s. Compensating supply of outdoor air by supply smoke ventilation with mechanical motivation can be provided by autonomous systems or using air supply systems to vestibule locks or elevator shafts. At the same time, specially designed openings with fire-fighting normally-closed valves and adjustable louver grilles should be provided in the fences of vestibule locks or elevator shafts to which the protected rooms are directly adjacent. The doors of the vestibule locks must be interlocked with the valve actuators in the bypass cycle. It is allowed to use overpressure valves in fire-fighting design with the required fire resistance limits. Compensating air flow from elevator shafts is allowed only for elevator installations with the "fire hazard" control mode. Elevator shafts with the "transportation of fire departments" mode and smoke-free stairwells of type H2 are not allowed to be used for such a device. SP 7.13130.2013 7.2 Removal of gorenje products in case of fire by exhaust ventilation systems should be provided for: e) from atriums and passages; 7.8 When removing combustion products from corridors, smoke intake devices should be placed in shafts under the ceiling of the corridor, but not below the upper level of the doorways of the evacuation exits.

The length of the corridor, (rooms, let's say open space) The amount per smoke detector must be: - no more than 45 m with a rectilinear corridor configuration; - no more than 30 m with the angular configuration of the corridor; - no more than 20 m with an annular (closed) corridor configuration. 7.10 To remove gorenje products directly from the premises of single-storey buildings, exhaust systems should be used with natural stimulation through shafts with smoke valves, smoke hatches or unlatched, non-blown lanterns. Parameters A and B sp 60 5.13. The specified parameters of the microclimate in residential, public, administrative and industrial buildings should be provided within the calculated parameters of outdoor air for the relevant construction areas, adopted, as a rule, according to SP 131.13330: parameters A - for ventilation and air-showering systems in the warm season; Parameters B - for heating, ventilation, and air-conditioning systems in the cold season, as well as for air conditioning systems in the warm and cold seasons. The outdoor air parameters for the transitional conditions of the year should be taken as: a temperature of 10 °C and a specific enthalpy of 26.5 kJ/kg, or outdoor air parameters at which the operating modes of equipment consuming heat and cold change. further see SP 131.13330.2012 table 10.1 SP 60.13330.2016 Heating, ventilation and air conditioning.
