väljatõmbeõhku

Väljatõmbeõhk refers to air that is actively removed from a building or enclosed space through a mechanical ventilation system. This process is distinct from natural ventilation, which relies on air currents and pressure differences. Väljatõmbeõhk systems are typically designed to extract air from areas where pollutants, moisture, or odors are generated, such as kitchens, bathrooms, and utility rooms.

The primary purpose of exhausting air is to maintain indoor air quality and control humidity levels. By removing stale or contaminated air, the system prevents the buildup of harmful substances and helps to create a healthier living or working environment. In many residential and commercial buildings, väljatõmbeõhk is a crucial component of a balanced ventilation strategy, often working in conjunction with supply air systems.

The extracted air is usually filtered and then discharged outside the building. The design and capacity of a väljatõmbeõhk system are determined by factors such as the size of the space, the expected occupancy, and the specific ventilation requirements. Energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs) can be integrated into väljatõmbeõhk systems to recapture some of the thermal energy from the outgoing air, thereby reducing heating and cooling costs. Proper maintenance, including regular cleaning or replacement of filters, is essential for the efficient operation of väljatõmbeõhk systems.
