Väljatõmbeõhk

Väljatõmbeõhk, also known as exhaust air, is the air that has been removed from an indoor space through a ventilation system. This air typically contains pollutants, moisture, and odors that have accumulated within the building. In mechanical ventilation systems, such as exhaust fans in kitchens or bathrooms,väljatõmbeõhk is actively drawn out of the building. In heat recovery ventilation (HRV) or energy recovery ventilation (ERV) systems, this outgoing air is utilized to pre-condition the incoming fresh air, thereby reducing energy consumption.

The composition of väljatõmbeõhk can vary significantly depending on the building's use and activities. In residential settings, it may contain cooking fumes, humidity from showers, and volatile organic compounds (VOCs) from cleaning products or furnishings. In commercial or industrial environments, the pollutants could include a wider range of chemicals, dust, or specific manufacturing byproducts.

The proper management of väljatõmbeõhk is crucial for maintaining indoor air quality and preventing issues like mold growth or condensation. When exhausted, it is typically expelled outdoors. In some advanced systems, the expelled air may undergo treatment before release to minimize environmental impact. The volume and rate of väljatõmbeõhk are key parameters in ventilation design, ensuring adequate air exchange for a healthy and comfortable indoor environment.
