"ventilation" from the Latin word ventilationcomes from (in turn ventus means wind). The said term to directly describe the importance of ventilation, in 1660 used and referred to the process of "replacing bad indoor air with clean and fresh air".
Humanity started thinking about different means of ventilation from the cave period and gradually improved it with new inventions and approaches...
1.5 million years ago, when man introduced fire into the dwelling for heating, he discovered the need for an opening in the roof to allow the smoke to escape and to supply air to sustain the fire. Combustion control and thermal comfort were the first incentives for space ventilation. Over the centuries, with the changes caused by the evolution of the industrial sphere and buildings, it gradually gave wings to ideas and created innovative and modern technologies adapted to its needs.
Let's see what path a person has taken, for the proper functioning of the building, in the process of creating this most important system.
Ancient Egyptians As a natural cooling mechanism and air movement, they used the so-called Hand fans. Also, in the pyramids there are tunnels that connect the royal tombs with the exit. The tunnels provided effective air exchange. of the Minoan period In some early buildings, there was a passive ventilation system created with a sophisticated design and scheme (for example Wind Towers), which was used for cooling buildings. Romans (3rd century BC) created the first underfloor heating, known as Hypocaust. By combining ventilation and combustion, they made the indoor climate in palaces and baths comfortable. These systems were first used in public baths, then in large buildings. Hypocaust was the forerunner of integrated heating and ventilation systems in buildings.
middle Ages, Ventilation was largely neglected. The houses had small windows and air supply was limited. You would only find ventilation solutions in the palaces or churches of the rich. The serious problem of air pollution, the deteriorating health of the population and numerous fires in 1631, convinced the king Charles I New building regulations were introduced in England. The monarch issued a decree to have roofs on houses throughout the country 10 feet or more tall, and the windows are higher and wider than the existing ones (to improve natural ventilation).
in 1735 In the Parliament of England, for the first time in history, a mechanical device was installed that drove a steam engine. The device was called a fan. It is interesting that the word for the first time "air conditioning" appeared in 1815, when the French Jean Shabanesh Received a British patent on the method of "air conditioning and temperature regulation in residential houses and other buildings".
At the end of the 19th century, American inventor Willis Carrier He created the first air conditioner that worked on electric energy. Carrier designed his first system in 1902 To control the temperature and humidity in the printing house in Brooklyn, New York, USA.
Thus, the first air conditioner served not for the comfort of the working staff, but for the fight against humidity, which had a very bad effect on the quality of printing. Soon the air conditioner was defined as a system that should have four main functions: Temperature regulation, humidity control, air circulation and air purification (filtration).
Widely sold air conditioners 1930s appeared in years. The first room air conditioning company General Electricreleased it. in 1958, The Japanese company Daikin presented the first heat pump that could supply both cold and hot air to the building. Another three years later, an event occurred that significantly determined the development of domestic and semi-industrial air conditioning systems. It was a mass production of split systems. The Japanese company Toshiba started serial production of air conditioners, which were divided into two blocks. The popularity of this type of air conditioners soon increased.
in 1968, Multisplit systems appeared on the market. in 1981 The first split-system that could self-regulate its power was presented. Since 1998, inverter air conditioners have gained popularity... these systems have improved over time and become smarter and more adapted to our lives. In the modern world, such technologies as, for example, are used in the direction of ventilation AHU (air handling unit, air handling unit), Rooftop (roof type air conditioner), recuperator and others.
Today, mechanical ventilation systems of buildings are subject to certain standards and norms. The system should be designed, installed, operated and maintained in a technically, hygienically and functionally sound manner. Modern technology has energy-efficient goals and significantly increases the quality and comfort of our lives.
