Flat Displacement Units: An Efficient Solution for Displacement Ventilation

Displacement ventilation is a highly effective method for achieving superior indoor air quality and thermal comfort. Within this category, flat displacement units have emerged as a popular choice for various applications. These units offer unique advantages in terms of energy efficiency, occupant comfort, and design flexibility.

What are Flat Displacement Units?

Flat displacement units are specialized ventilation devices designed to deliver fresh, conditioned air at a low velocity near the floor level. Unlike traditional overhead air distribution systems, which mix air throughout the space, flat displacement units create a stratified environment by displacing stale air upwards and out of the occupied zone. These units are characterized by their slim, low-profile design, making them ideal for spaces with limited ceiling height or architectural constraints.

How do Flat Displacement Units Work?

Flat displacement units operate on the principle of buoyancy. They introduce cool, conditioned air through diffusers located at the floor level. This cool air, being denser than the warmer air in the room, spreads across the floor and gradually rises as it absorbs heat from occupants and equipment. The warm, contaminated air naturally rises to the ceiling level and is extracted through exhaust grilles, creating a continuous, unidirectional airflow pattern.

Where are Flat Displacement Units Commonly Used?

Flat displacement units are well-suited for a wide range of applications, including:

• Offices and commercial buildings
• Hotels and hospitality spaces
• Educational institutions
• Healthcare facilities
• Data centers and server rooms
• Museums and libraries

What are Installation Best Practices for Flat Displacement Units?

Proper installation is crucial for the optimal performance of flat displacement units. Some key installation best practices include:

• Careful unit selection: Choose a unit with appropriate airflow capacity and diffuser configuration for the space.
• Strategic diffuser placement: Position diffusers along external walls or areas with high heat loads to maximize air distribution.
• Adequate exhaust ventilation: Ensure sufficient exhaust capacity to remove displaced air and maintain a balanced ventilation system.
• Proper ductwork design: Use short, direct duct runs with minimal bends to minimize pressure drop and noise levels.
• Regular maintenance: Schedule routine inspections and cleaning of the units, filters, and diffusers to ensure long-term performance.

What are the Top Manufacturers for Flat Displacement Units?

The market for flat displacement units is served by several reputable manufacturers, including:

• Price Industries
• Halton
• Swegon
• Lindab
