The Fujitsu BS box, also known as the Fujitsu air-handling unit, is a highly advanced and efficient device that works in conjunction with an outdoor unit to provide heating, ventilation, and air conditioning (HVAC) to a space. The BS box is responsible for circulating air throughout the space, while the outdoor unit handles the heating and cooling functions.
Understanding the Fujitsu BS Box’s Air Circulation Process
The Fujitsu BS box works by drawing in air from the space, passing it over a heat exchanger, and then distributing the conditioned air back into the space. The heat exchanger can either add or remove heat from the air, depending on the season and the desired temperature setting. The air is then distributed through a series of ducts and vents, ensuring even and consistent temperature control throughout the space.
Key Components of the Air Circulation System
-
Air Intake: The BS box is equipped with an air intake that draws in air from the surrounding space. This intake is typically located on the top or side of the unit, depending on the model and installation requirements.
-
Heat Exchanger: The heart of the BS box is the heat exchanger, which is responsible for either adding or removing heat from the incoming air. The heat exchanger is a complex system of coils and fins that facilitate the transfer of thermal energy.
-
Blower Fan: The blower fan is responsible for circulating the conditioned air throughout the space. This fan is strategically positioned to ensure efficient air distribution.
-
Ductwork: The conditioned air is then distributed through a network of ducts and vents, ensuring even and consistent temperature control throughout the space.
Modulation Capabilities of the Fujitsu BS Box

One unique feature of the Fujitsu BS box is its modulation capabilities. Modulation allows the unit to adjust its output based on the current temperature and load requirements of the space. This results in more efficient operation and improved comfort levels for the occupants.
Modulation Principles and Benefits
-
Demand-Based Adjustment: The BS box continuously monitors the temperature and load requirements of the space, adjusting its output accordingly. This ensures that the unit only operates at the necessary capacity, rather than running at full capacity all the time.
-
Energy Efficiency: By modulating its output, the Fujitsu BS box can significantly reduce power consumption and operating costs, making it a more energy-efficient HVAC solution.
-
Improved Comfort: The modulation capabilities of the BS box allow for more precise temperature control, resulting in a more comfortable and consistent indoor environment for the occupants.
Advanced Features and Settings of the Fujitsu BS Box
The Fujitsu BS box includes a variety of advanced features and settings to enhance its performance and usability. These features include:
Remote Control Capability
