Thisstandard focuses on the devices being used in the construction of pressure differential systems. It determines the components of device kits, how to divide them into families and what tests should be carried out on individual kits. The goal of these tests is to prove that a given device kit can create the required level of overpressure, as well as directional airflow from the space protected with overpressure to the adjacent space. Ventilation systems designed in accordance with PN-EN 12101-13 should consist of components tested in accordance with PN-EN 12101-6, which meet requirements of this standard.

The standard divides the device sets into three basic groups, depending on the solution to be applied to the overpressure control in the protected space by means of the following:

1. a barometric damper;

2. a damper working with the pressure regulator and sensor;

3. and pressure sensors, regulators and frequency converters.

PN-EN 12101-13:2022 includes guidelines for the design of pressure differential systems. The fundamentals have not changed, in that it is still necessary to supply air to the protected space in order to create overpressure and it is still necessary to vent off the air from the storey engulfed in fire. What is important though, is that the standard allows for the design of overpressure systems only. Systems based on underpressure have been removed.

As can be seen from the table above, one of the new criteria is the response time of the pressure differential system, which should be measured during commissioning. In addition, the requirement to maintain 10 Pa within the staircases when the end door was open, has also been removed from the standard, which significantly increased the air streams required for the system. It is also worth mentioning that the standard introduces a 30 Pa minimum overpressure level for all protected spaces, which means both the staircases and atria (if present).

The air stream that should be supplied to the staircase or the lift/elevator shaft, according to the new standard, is established just as in the previous version of the standard, namely, the air stream necessary for the pressure criterion and the air stream necessary for the flow criterion should be determined and then the greater one should be selected.

Some interesting changes have been introduced in establishing the leakage area, which is the basis for determining the air stream necessary for the pressure criterion. The standard introduces additional leakage areas for lift/elevator shafts, which makes it possible to reduce the leakage areas of the doors of new elevator shafts and therefore decrease the air streams required.

One of the significant issues in the new standard is the approach to the pressure differential system design for buildings with a height of at least 60 m. In such high buildings, additional factors might influence the parameters to be achieved by the pressure differential system, such as wind or the stack/chimney effect. Therefore, the systems serving high spaces require special attention and the standard has a requirement to conduct an additional pressure distribution analysis, as early as the design stage for such projects.

Numerical methods (CFD) are one of the tools that can be used in pressure differential system design. Without doubt, this is beneficial because it promotes more conscious design and helps to catch any mistakes at the design stage when it is easy to make any necessary changes.

The standard also recommends the placement of a sign near the entry of a staircase at firefighter access level which displays the information that the staircase is protected by the pressure differential system. It should be the graphical symbol that is shown in the standard.

The most important changes introduced in the new standards are described above, however, there are many more changes. It would be impossible to describe them all in a single article, so we will surely publish more information on this subject in the future.

Not only for fleeing individuals, smoke gases pose the greatest threat in the event of a fire. They also endanger and hinder the rescue teams. Electronic staircase pressurisation systems offer the highest level of fire protection. They ensure your safety when it counts and are crucial for saving lives and fast firefighting. To achieve this, the entire system must function properly and reliably.

Safety of the people in the building is the top priority. With a Systemair differential pressure system, you can be sure that smoke-free escape and rescue routes are guaranteed in the event of a fire.

Due to the testing of our kits in accordance with EN 12101-6:2022-11, you know exactly what you are getting when you use Systemair components in your project. You can also be sure that you can rely on them to function perfectly

A total of four tested kits are available for different applications. The kits form the core of the overall system and are not available separately. Depending on the size and scope of the project, they can be extended to include control cabinets for the control system, dampers, smoke extraction dampers, field devices and other components. Below you will find an overview of the available kits. Detailed information on the standard and the kits can be found in our whitepaper.

The kit RDA 2 is used for differential pressure systems with mechanical outflow. Similar to RDA 1, the supply air is generated using an axial fan with frequency converter, braking resistor and pressure sensor.

Pressure relief damper EKO-JVH is a self-acting damper that is part of the pressurization system EKO SafeEvac and complies with EU Standard EN 12101-6. The damper keeps the overpressure constant in escape routes such as stairwells and elevator shafts during pressurization activated in the event of fire.

It has weight-laden damper blades that maintain the calculated overpressure for the stairwell or elevator shaft. The damper is intended for vertical mounting. Pressure relief damper EKO-JVH is used together with roof duct EKO-T and smoke hatch EKO-BRL which is equipped with an opening unit for 160 opening with 24 V actuators.

Desde la publicacin de la norma UNE EN 12101-6 el conocimiento de la misma por parte de los proyectistas e instaladores as como el diseo de los sistemas de presurizacin ha ido progresivamente en aumento. Pese a ello, existen algunos aspectos de la norma como la seleccin de la clase de sistema de presurizacin en funcin de las caractersticas de compartimentacin del edificio, del objetivo del sistema de presurizacin ( evacuacin o actuacin de bomberos ) y del tipo de evacuacin prevista para el mismo ( solo de la planta del incendio, por fases o simultanea ) que en ocasiones no se tienen en cuenta en el diseo y que son determinantes para el correcto funcionamiento del sistema de sobrepresin en caso de un incendio.

La citada norma, de mbito europeo detalla los requerimientos para los sistemas de presin diferencial, permitiendo el dimensionado del sistema de presurizacin para 6 tipos de sistemas en funcin de cul sea el objetivo del mismo, objetivos que van desde permitir la evacuacin segura solo de los ocupantes que ocupen la planta afectada por el incendio (sistema tipo A) hasta permitir una ms eficaz y segura intervencin por parte de los bomberos en condiciones de fuego muy avanzado (sistema clase F), siendo responsabilidad del diseador la seleccin del sistema ms adecuado en cada caso.

Sistema clase A: Para medios de escape. Defensa in situ: Las condiciones de proyecto se basan en asumir que el edificio no ser evacuado, a menos que est directamente amenazado por el incendio. El nivel de compartimentacin del fuego es normalmente seguro para los ocupantes que permanecen dentro del edificio

Sistema clase B: Para medios de escape y lucha contra incendios: Se puede utilizar un sistema de presin diferencial de clase B para reducir al mnimo las posibilidades de contaminacin grave por humo de los puestos de control contra incendios , durante las operaciones de los medios para evacuacin de personas , y de los Servicios de Extincin.
