Fan Coil Unit - FCU HVAC

The video tutorial explains fan coil units (FCUs), their components, and their role in air conditioning systems. It covers how FCUs condition air to meet temperature requirements, the distribution and recirculation of air, and the components involved, such as fans, heating and cooling coils, and filters. The tutorial also discusses the heating and cooling processes, including condensation management, and provides a schematic overview of FCU systems, highlighting variations in design and operation.

What does FCU stand for in the context of building systems?

• Filtered Cooling Unit

• Fan Coil Unit

• Fresh Cooling Unit

• Forced Circulation Unit

Which of the following is NOT a typical location for fan coil units?

• Outdoor Parks

• Bars

• Offices

• Canteens

How is fresh air typically introduced into a space using a fan coil unit?

• Using portable air purifiers

• Directly through windows

• Via a gap near the FCU inlet

• Through ductwork connected to the FCU

What is the primary function of the fans inside a fan coil unit?

• To dehumidify the air

• To filter dust from the air

• To humidify the air

• To circulate air through heating and cooling coils

What happens to the air after it passes through the heating and cooling coils in a fan coil unit?

• It is released into the atmosphere

• It is recirculated back into the same space

• It is discharged through ductwork to the required areas

• It is stored in a reservoir for later use

What is a common consequence of cooling air using a cooling coil in a fan coil unit?

• Increased noise levels

• Increased air pressure

• Generation of condensation

• Decreased air quality

In a fan coil unit, what is the purpose of the drip tray?

• To collect dust particles

• To store extra cooling fluid

• To hold excess air

• To collect condensation water

What is the role of the main AHU in a building's air handling system?

• To filter water for the building

• To act as a backup for FCUs

• To supply fresh air to the building

• To provide heating only

Which of the following is NOT a typical component of a fan coil unit?

• Cooling coil

• Heating coil

• Water reservoir

• Air filter

What type of water is typically used in the heating coil of a fan coil unit?

• Cold water

• Distilled water

• Salt water

• Hot water
