What is air recirculation?

Air recirculation is when the circulation device moves through the air in an enclosed space around more than once. Such devices can serve personal or commercial purposes. They use and adapt to many circumstances, from households and cars to industrial buildings and laboratory clean rooms. Air recirculation holds out or limits the amount, the outer air coming into the space to prevent pollutants, undesirable odors and helping air conditioning.

Air recyculation systems recycle the air already contained in space and check the amount of new air entering this space; In many cases, they also pass through the old air filter system. Simple home fans can be considered as a form of air recirculation, even if they do not provide filtration and circulate only air in a very limited space.

Small fans are mainly used to ensure insulated artificial breeze, while air recirculation systems are designedk to maintain a solid flow of air and the quality of the inner air throughout the whole Avoce or the building. Air recirculation can also help control temperatures, as air conditioning systems can be more efficient in re -heating or re -cooling that has passed through the system several times. Buildings in colder climate use air recirculation to maintain cold air and contribute to thermal conditioning.

If they are not well designed and maintained, recirculation systems of air may worsen the respiratory conditions and lead to the propagation and concentration of air contaminants. In closed areas - the fastest in small areas, such as in the compartment of the car - hazardous carbon monoxide levels may develop if fresh air is completely blocked at the entrance for a longer period of time. Many car manufacturers add carbon dioxide detectors to solve this potentially serious problemSafety guards into their recirculation of air and conditioning. People can choose to install carbon dioxide detectors in households and, in some US countries and other jurisdictions, the installation has become mandatory.

There are certain circumstances under which specially adapted systems are needed for unique purposes. In the case of buildings in which industrial processes are carried out, suitable ventilation is required and air recirculation systems are designed to regularly bring the necessary amount of fresh air and exclude contaminated air. In the laboratory clean room, which is maintained with the smallest possible contaminants for research or production purposes, a particularly strong air flow is necessary to ensure hygiene.
