Treated fresh air (TFA) units are heating, ventilation, and air conditioning (HVAC) systems designed to improve indoor air quality by introducing filtered and conditioned outdoor air into a building. TFAUs help to reduce the amount of recirculated air, which can be a source of indoor air pollution, and increase the amount of fresh air brought in from outside.

These units typically consist of a ventilation system, a heat recovery system, and filters to remove particulate matter and pollutants from the outdoor air. The ventilation system brings in outdoor air and distributes it throughout the building, while the heat recovery system helps to maintain comfortable indoor temperatures by exchanging heat between the incoming and outgoing air streams.

Treated Fresh Air units are commonly used in commercial and institutional buildings, such as hospitals, schools, and office buildings, to improve indoor air quality and reduce the risk of airborne infections. By providing a steady supply of fresh, filtered air, These units can help to create a healthier and more comfortable indoor environment for occupants.

Treated Fresh Air Unit Working Principle

The working principle of a Treated Fresh Air unit involves three main stages: intake, treatment, and delivery. During the intake stage, fresh air is drawn into the unit from outside the building. The air is then treated by passing through a series of filters, which remove airborne particles and pollutants. The treated air is then conditioned by adjusting its temperature and humidity levels. Finally, the treated and conditioned air is delivered to the building’s interior spaces through a duct network.

Benefits:

1. Improved Indoor Air Quality: Treated Fresh Air units supply fresh air from outside the building after filtering, which helps to improve indoor air quality by removing pollutants and contaminants.
2. Comfortable Indoor Environment: TFA units regulate temperature and humidity levels, creating a comfortable indoor environment for building occupants.
3. Energy Efficiency: Treated Fresh Air Units units use heat recovery technology to recover and reuse energy, making them an energy-efficient choice.
4. Reduced Operating Costs: By recovering and reusing energy, TFA units can reduce operating costs, making them a cost-effective choice in the long run.

Features:

1. Filtration: These units have advanced filtration systems that remove airborne particles and pollutants, helping to create a healthier indoor environment.
2. Heat Recovery: It uses heat recovery technology to recover and reuse energy, reducing energy consumption and operating costs.
3. Humidity Control: TFA units regulate humidity levels, creating a comfortable indoor environment and preventing the growth of mold and mildew.
4. Temperature Control: TFA units regulate temperature, ensuring that the indoor environment is comfortable for building occupants.
5. Customizable: TFA units are customizable and can be designed to meet the specific requirements of a building.
6. Low Noise: TFA units operate quietly, ensuring that building occupants are not disturbed by the noise.
