Ventilation systems are designed to regulate and control the air quality, temperature, and humidity of a building or space in order to create a controlled and comfortable indoor environment. These systems ensure fresh air circulation, remove pollutants, odors, and excess moisture, playing an important role in maintaining a healthy and comfortable living or working environment.

Ventilation systems may vary in complexity and design depending on the specific requirements of the building or space.

Main components of ventilation systems

Air intake:
Fresh outdoor air is introduced into the system through ventilation ducts or openings.

Air filtration:
Incoming air is filtered from dust, pollen, and other particles, improving indoor air quality.

Air mixing and conditioning:
Fresh air is mixed with recirculated indoor air and brought to the desired temperature and humidity level. Heating and air conditioning components operate at this stage.

Distribution:
Conditioned air is distributed throughout the entire space via air ducts, vents, and diffusers.

Exhaust:
Stale air, pollutants, and odors are removed from the indoor environment through exhaust outlets.

Control and automation:
Modern ventilation systems are equipped with smart control and automation technologies for precise regulation of temperature, humidity, and airflow.

Advantages of efficient ventilation systems

  • Improved indoor air quality – pollutants and allergens are removed.

  • Temperature and humidity control – a comfortable indoor environment is ensured.

  • Energy efficiency – properly designed systems optimize energy consumption.

  • Moisture control – prevention of mold and dampness issues.

The main purpose of a boiler house is to supply consumers (for industrial or heating purposes) with hot water and/or steam.

Heat production is mainly carried out in boilers through the combustion of fuel, and the process itself is implemented by means of heat exchange and convection.

Boilers used in boiler houses differ by the type of fuel: gas, diesel, or gas-diesel. They are also classified according to the type of energy carrier produced: hot water or steam.

As a rule, steam boiler houses are used in agriculture and industry, while hot water boiler houses are used to provide heating and hot water supply for residential and public buildings.

Boiler houses are classified according to the following parameters:

  1. By type of location: central, district, individual, and modular (block-type)
  2. By type of fuel used: gas, solid fuel (coal, firewood, pellets, wood chips, peat, etc.), diesel, combined (gas-diesel)
  3. By type of boilers: steam, hot water, thermal oil
  4. By heat load: for residential buildings, industrial facilities, public buildings, etc.

Types of Fire Protection Systems

Based on the extinguishing medium, fire protection systems are divided into the following groups:

Water-based fire suppression systems

(sprinkler and deluge systems) – these systems operate by directly spraying water onto the fire. Their advantage is high effectiveness in areas where there is a risk of rapid fire spread or where cooling of the facility is required.

Water mist fire suppression systems

These systems use water mist technology, breaking water droplets into particles smaller than 50 microns (µm). At high temperatures, these particles evaporate rapidly. This process cools the protected area and reduces oxygen concentration around the fire source. The advantage of these systems is lower water consumption and reduced risk of water damage or flooding.

Foam-based fire suppression systems

These systems work by covering or filling the burning area with foam, isolating it from oxygen. Foam systems are typically similar to water-based systems, where a foam concentrate is added to water and then mixed with air. At the discharge point, nozzles, ejectors, foam chambers, water-foam monitors, or foam outlets are used. Advantages include isolating the fire from fuel, cutting off oxygen, and preventing water saturation of the protected equipment.

Gas-based fire suppression systems

These systems work by displacing oxygen from the protected area and/or chemically interrupting the combustion process. Gas suppression is one of the safest methods for areas containing electronic equipment, as gases are non-conductive and do not damage electronics.

Powder-based fire suppression systems

These systems use the antikatalytic effect of fire-extinguishing powder, which stops the combustion process and extinguishes flames. They are less commonly used and are applied where other systems are not feasible or economically efficient. Their advantages include effectiveness in sub-zero temperatures and environmental safety.

Fire suppression equipment can also be classified based on the type of protected area. In large-volume facilities, water, foam, or water mist systems are typically used, while gas systems are applied in spaces up to approximately 1000 m³. In smaller facilities, deluge or water mist systems may be used.

Gas suppression systems or special solutions (such as Automatic Active Fire Suppression Lines) can be used to extinguish fires occurring during the operation of machinery and electrical equipment.

Passive Fire Protection

Another method of fire prevention is passive fire protection. This approach involves slowing down or stopping the spread of fire by using appropriate materials, equipment, and fire safety procedures in the building design.

The main elements of passive fire protection are Fire Detection and Fire Alarm Systems (FAS). This system includes:

  • Fire Alarm System (FAS)

  • Voice Evacuation System (VES)

The FAS system detects fire at an early stage and transmits the alarm to the control panel, which then notifies responsible persons or organizations.

The VES system is used to broadcast warning signals and voice announcements. These announcements are automatically activated when a signal is received from the fire alarm system.

Smoke Extraction Systems

Smoke extraction (SE) systems are designed to remove fire gases (smoke) from a space and replace them with fresh air to compensate pressure differences, ensuring survivability and breathable conditions for occupants.

Smoke extraction systems are divided into the following types:

  • Gravity systems

  • Mechanical systems

  • Hybrid systems

  • Overpressure systems

The gravity system uses convection – the principle that hot smoke rises upward.

Mechanical systems remove fire gases using fans and jet devices.

Hybrid systems combine both smoke extraction and smoke control functions.

Overpressure systems prevent smoke from entering protected areas by controlling airflow direction and pressure differences, maintaining the highest pressure in evacuation routes.

Smoke extraction systems are also divided into ducted (vertical air ducts) and ductless (horizontal airflow / jet ventilation) systems.

Where Should Fire Protection Systems Be Applied?

These systems should be installed in all facilities where people are present and where goods produced by human activity are stored.

They are especially required in the following facilities:

  • Commercial and exhibition buildings

  • Theaters with more than 300 seats

  • Cinemas with more than 600 seats

  • Catering facilities with more than 300 seats

  • Sports and concert halls with more than 1500 seats

  • Hospitals with more than 200 beds

  • Psychiatric hospitals with more than 100 beds

  • Social and rehabilitation centers with more than 100 beds

  • Enterprises employing more than 100 people with disabilities

  • High-rise public buildings

  • Collective residential buildings with more than 200 beds

  • National archives

  • Museums and historical monuments

  • Server rooms and data processing centers

  • Telephone exchanges

  • Garages larger than 1500 m² or with multiple underground levels

  • Metro and underground railway stations

  • Stations with more than 500 people at the same time

  • Banks with customer areas larger than 500 m²

  • Libraries and archives containing rare publications

Components of Fire Ventilation Systems

A traditional ducted fire ventilation system consists of the following:

  • Ventilation ducts

  • Air grilles

  • Exhaust fans

  • Fire dampers

Special attention must be given to evacuation routes (stairs and garages).

Fire gases and smoke can intoxicate people and make evacuation impossible. Fire ventilation controls airflow and smoke movement so that smoke and gases are removed as quickly as possible, facilitating safe evacuation.

Types of Fire Ventilation Systems

Based on purpose and equipment used, systems are classified as follows:

SHEVS (Smoke and Heat Exhaust Ventilation System)

Removes the smoke layer accumulated under the ceiling and maintains a smoke-free zone, allowing safe evacuation.

Smoke and Heat Control System

Controls smoke between the fire source and the extraction zone, ensuring access for emergency services to the fire source.

Smoke Clearance (Dilution) System

Removes smoke and dilutes it with incoming replacement air, reducing its temperature and toxicity.

A smoke control system is a system that controls the movement of smoke and air within a building. This system may consist of various components and may use several methods to achieve the design objective. The main goal is usually to maintain a safe (tenable) environment for a sufficient period so that all occupants can safely evacuate the building.

The design objective of a smoke control system may vary depending on the application. For example, in a hospital, the goal may be to contain the smoke within the zone where the fire originated. These systems may be part of existing HVAC systems or installed as separate (independent) systems.

There are several methods of smoke control. Smoke control systems include two types:

  • Smoke management systems

  • Smoke containment systems

Smoke containment systems prevent smoke from entering certain areas by creating pressure and are typically used in enclosed stairwells.

Smoke management systems, on the other hand, maintain a safe environment in evacuation routes in large-volume spaces or prevent smoke from spreading to adjacent areas. These systems are mainly installed in buildings with multi-story atriums.

Smoke Containment Systems

There are several types of smoke containment systems used for small and enclosed spaces:

  • Stairwell pressurization

  • Zone smoke control

  • Elevator shaft pressurization

  • Vestibule pressurization

  • Smoke refuge area pressurization


Most of these systems operate on a similar principle. Pressure is applied to a specific area (such as a stairwell, elevator, vestibule, or building zone) using a mechanical fan. The pressure difference across a barrier prevents smoke from entering that area.

This allows these areas (usually evacuation routes) to remain safe for a longer period, providing occupants with additional time to evacuate and enabling emergency services to operate effectively.

Smoke Management Systems

Smoke management systems used for large spaces such as warehouses or atriums include:

  • Mechanical smoke exhaust

  • Natural smoke ventilation


Natural ventilation removes smoke by using its tendency to rise, while mechanical smoke exhaust systems use fans to remove smoke and air from the building.

The objective of these systems is typically to maintain the smoke layer interface above the highest usable level of the space for a specified period.

Mechanical smoke exhaust systems must provide a path for make-up air. Otherwise, the pressure may increase to a level that negatively affects other building systems.

For example, the pressure difference across a door should not increase the force required to open it beyond 30 lbf (133 N), otherwise the door may become too heavy for occupants.

It is also important that the make-up air is clean and fresh and not drawn from the area where smoke is being exhausted.

Activation

Both smoke management and smoke containment systems are automatically activated by one or more fire detection devices. These include:

  • Sprinkler water flow detectors

  • Smoke detectors

  • Heat detectors

Manual activation devices should not be used in smoke control systems that are required to determine the location of a fire, because the likelihood of someone manually activating the system in the fire area is low.
