What is a ventilation system?
In general, a ventilation system is an indoor air-conditioning system that provides fresh air to the interior of a building. This is done to reduce the humidity, and in some cases, to reduce the concentration of CO2.
What is the function of a ventilation system?
A ventilation system provides a relatively constant flow of fresh air through a building. This is done to keep the air quality in the building constant. A ventilation system may also be used to help in case of fire or other emergencies.
Why is a ventilation system needed?
The amount of moisture and the concentration of CO2 in the indoor air of a building can be increased by 40% to 80% due to the lack of fresh air.
The carbon dioxide can cause damage to the building's interior due to its excessive concentration.
A well-designed ventilation system can make the air of a building healthier, making it a desirable place to work or live.
What is the function of the Duct Calculator?
The Duct Calculator provides an extensive set of functions for the calculation of the size and pressure loss of round and rectangular ventilation ducts. The input of the desired size (volume flow, air velocity, or dimension) can be selected.
