õhkuvahetuse

Õhkuvahetuse, also known as ventilation, is the process of exchanging or replacing air in a space to provide high indoor air quality and thermal comfort. It is a critical aspect of building design and operation, particularly in enclosed spaces such as buildings, vehicles, and submarines. The primary goals of ventilation are to remove contaminants, odors, and excess heat or humidity, and to supply fresh air.

There are several types of ventilation systems, including natural ventilation, mechanical ventilation, and hybrid systems. Natural ventilation relies on the natural movement of air due to temperature differences, wind, or buoyancy. Mechanical ventilation uses fans, ducts, and other equipment to circulate air. Hybrid systems combine both natural and mechanical ventilation methods.

The design and implementation of ventilation systems depend on various factors, such as the size and purpose of the space, the climate, and the specific requirements for air quality and thermal comfort. Proper ventilation is essential for maintaining a healthy indoor environment, preventing the buildup of harmful substances, and ensuring the comfort and well-being of occupants.
