Horizontal Concealed Fan Coil Unit: A Space-Saving HVAC Solution for Modern Buildings
With modern architecture demanding both comfort and aesthetics, HVAC systems must provide efficient climate control without compromising interior design. Horizontal concealed fan coil units (FCUs) are designed to meet these needs, offering reliable cooling and heating performance while being hidden within ceilings or concealed spaces.
This type of fan coil unit is widely used in hotels, apartments, offices, hospitals, and commercial buildings where quiet operation, flexibility, and space efficiency are crucial.
What Is a Horizontal Concealed Fan Coil Unit?
A horizontal concealed fan coil unit is a compact indoor air conditioning terminal unit, installed horizontally above the ceiling, within a suspended ceiling, or in a concealed space. It is typically connected to a chilled or hot water system and delivers treated air through ductwork or direct exhaust vents.
The unit includes:
● High-efficiency fan
● Heat exchange coil
● Air filter
● Condensate pan
● Control system
Due to its concealed design, only the vents or diffuser are visible, maintaining a clean and modern interior aesthetic.
Key Advantages of Horizontal Concealed Fan Coil Units
1. Space-Saving, Concealed Installation
The horizontal, concealed design allows the units to be installed above ceilings or in confined spaces, making them ideal for projects with limited server room space.
2. Quiet Operation
Utilizing low-noise fans and optimized airflow design, concealed fan coil units provide a quiet indoor environment, making them ideal for hotels, offices, and residential buildings.
3. Flexible Air Delivery Methods
These units can be connected to short duct systems, delivering air to multiple outlets to improve indoor comfort distribution.
4. Energy Efficient
When used in conjunction with chillers or heat pumps, horizontally concealed fan coil units achieve efficient temperature control and low energy consumption, helping to reduce operating costs.
5. Design Freedom
Due to the concealed design, architects and designers have greater freedom in interior layout, without the concerns associated with exposed HVAC equipment.
Typical Applications
Horizontal concealed fan coil units are commonly used in:
● Hotels and resorts
● Residential apartments and villas
● Office buildings
● Hospitals and medical facilities
● Commercial spaces
● Educational buildings
They are particularly suitable for projects that prioritize comfort, noise control, and minimalist interior design.
