Passive displacement cooling gently delivers cool air via buoyancy. As the air absorbs heat from people, lights and equipment, it rises and is collected at the ceiling, then cooled again through the coil before repeating the cycle. By relying on natural buoyancy instead of high fan power, this approach operates quietly, uses significantly less energy and serves as a low-carbon alternative to conventional air-conditioning. Our IET Singapore event is open to both IET members and non-members.
