It is often said that all genius is simple. Comfort is also in simplicity, and the predecessor of fire ventilation in the history of mankind remains a reliable foundation to this day.
The history of the origin of fire ventilation systems begins in the 19th century. Long before the invention of electricity, in the 1840s, Florida physician and inventor John Gore thought that refrigeration could prevent disease and create a comfortable environment for humans. It was for this purpose that he created a cooling system consisting of huge blocks of ice, which had to be transported from frozen lakes and streams in the north. The logistics were unreasonable, so he invented an ice machine. In 1851, he created the first machine that made ice, but due to limited finances, he could not introduce it to the general public. However, the invention is considered the forerunner of the modern cooling system.

Engineer Willis Carrier, who worked for the Buffalo (NY) Forge Company, was tasked with solving a moisture problem at a Brooklyn publishing house as newspaper pages were warping after printing. Through a special cooling pipe, which had the shape of a coil, air was brought into the building, and the heating of water in the air was humidified by cooling. Willis soon realized that the device would be of interest to other types of businesses as well. So he left Buffalo Forge and formed his own company, Carrier Engineering Corporation, with six other engineers.
In 1922, Carrier Engineering Corporation installed the first cooling system in theaters in Los Angeles. Air was pumped through taller fans, resulting in more even cooling. In 1925, a centrifugal cooling system installed in New York’s Rivoli Theater was a breakthrough in HVAC inventions. Although it was more reliable and less expensive than previous systems, it was still too large and expensive for widespread use.

Since 1947, AC units have become more compact and cheaper. By the 1960s, most new homes in the United States were built with central air conditioning.
We know that heating and cooling systems help keep us comfortable, but they also ensure safety and minimize the risk of property damage in the event of a fire.

A fire is dangerous not only because of an open fire, but also because a large amount of smoke accumulates in the building, which makes it difficult to breathe, makes orientation in space difficult, and causes panic. For this purpose, it is necessary for the building to have an appropriate fire ventilation and smoke extraction system.
Nowadays, ventilation systems can control the movement of smoke in the event of a fire. By controlling the flow of smoke, these systems help improve visibility and provide safe evacuation routes for people.

Ventilation systems are vital for creating a quality microclimate in the interior of the building. Ventilation systems can also help control heat build-up during a fire. By moving hot air and gases outside, these systems help limit the spread of fire and reduce the risk of structural damage.
In addition, fire ventilation systems can provide firefighters with controlled air supply to the building. This helps them navigate through smoke-filled areas.

In today’s world, effective ventilation with optimal air exchange efficiency, well-designed air ducts and controlled airflow direction is not just nice – it is essential for our safety.
