Displacement ventilation is an innovative air distribution system that is becoming increasingly popular in modern buildings. This system works by supplying air at a low velocity and temperature at floor level or in the occupied zone of the space. The cool air displaces the warm air, which rises and creates a stratified thermal layer, resulting in a comfortable and energy-efficient environment. Displacement ventilation is particularly suitable for spaces where the occupants remain in a seated position, such as classrooms, auditoriums, and conference rooms. One of the key benefits of displacement ventilation is that it provides superior indoor air quality compared to traditional air conditioning systems. This is because the low-velocity air flow reduces the spread of airborne pollutants, such as dust, allergens, and bacteria. Additionally, the system eliminates the need for high-velocity air and associated noise levels, resulting in a quiet and peaceful environment. Displacement ventilation is also highly energy-efficient, as it reduces the amount of energy required to cool or heat a building. This is because the system operates at a lower temperature and uses less energy to circulate air. Furthermore, the system is well-suited for use in highly insulated and airtight buildings, as it helps to reduce the risk of convective heat loss. In terms of design, displacement ventilation offers greater flexibility compared to traditional air conditioning systems. This is because it eliminates the need for complex ventilation ducting, allowing for more design freedom and reduced construction costs. Overall, displacement ventilation is a highly effective and efficient air distribution system that offers numerous benefits for building owners, occupants, and designers. Its low-velocity air flow, superior indoor air quality, and energy efficiency make it an ideal choice for modern buildings.

Displacement ventilation is a type of air conditioning system which circulates air in an environmentally friendly way by using a low level, horizontal air flow. The air is supplied in a low velocity, low turbulence flow, which is then directed towards occupied areas of the building through floor-mounted diffusers. This method of ventilation enables the air to remain at a low temperature and has been proven to reduce the spread of airborne pollutants, create a comfortable environment and deliver significant energy savings. This system eliminates the need for high-velocity air and the associated levels of noise, enabling the occupants to enjoy a noise-free environment. Displacement ventilation also reduces the risk of draughts as the air is injected at low velocities. Additionally, this system is well suited for use in highly insulated and airtight buildings, as it helps to reduce the risk of convective heat loss. Displacement ventilation is particularly beneficial for designers as it eliminates the need for complex ventilation ducting, allowing for more design flexibility and reduced construction costs.

Displacement ventilation is an air distribution system where air is supplied at a low velocity and relatively low temperature at floor level or in the occupied zone of the space. This allows the air to naturally rise and create a stratified thermal layer, which is beneficial for thermal comfort and energy efficiency. This type of system is also called low velocity zone system or induced airflow system. It is particularly suitable for spaces where the occupants remain in a seated position, such as classrooms, auditoriums, and conference rooms.
