TREATED FRESH AIR UNITS ( TFA )

What are Treated Fresh Air Units? TFA refers to Treated Fresh Air, a specific type of air handling unit (AHU) used in heating, ventilation, and air conditioning (HVAC) systems. TFA units are engineered to enhance indoor air quality by introducing fresh air from the outdoors. Additionally, TFA units can function using refrigerant gases, which fall under the Direct Expansion (DX) Units category.

Usage Typically, TFA units are utilized in lobbies, passageways, or spaces where a slight temperature variation is needed in comparison to the outdoor climate. The main goal of employing TFA units is to introduce filtered air indoors, maintaining a temperature difference of approximately 4°C to 6°C relative to the outside temperature.

Conclusion   In summary, Treated Fresh Air Units are a superb option for buildings that prioritize indoor air quality. They provide numerous advantages and features that foster a comfortable, healthy, and energyefficient atmosphere for occupants, all while minimizing operating expenses.
