How it works
Displacement, without the fan.
Passive Displacement Cooling (PDC) operates similarly to conventional active displacement cooling. Cooled air is supplied at floor level, while warm air rises and is extracted at ceiling level.
To accommodate different design constraints and space requirements, three main models are available:
- Full-height PDC
- Half-height side-throw PDC
- Half-height down-throw PDC
01
Warm air gravitates towards the coil
Heat generated by occupants, lighting and equipment warms the room air. The warmer, lighter air rises and moves towards the PDV coil.
02
The chilled-water coil removes heat
Chilled water flows through the coil and absorbs heat from the surrounding room air. As the air is cooled, it becomes denser.
03
Cool air descends naturally
The cooler, denser air descends through the insulated PDV casing and is discharged through the air grille.

What happens next
The findings hand straight to Engineering & Integration, and the measures they name are the ones Measurement & Verification later proves.

Prose
Rich text scope
Editor-authored HTML sits inside the prose scope, so headings, lists and quotes take the article styles without restyling the page around them.
- Red-rule bullets at body scale.
- Second item.
- Numbered list.
- Second step.
Measure before and after every intervention so the saving is proven rather than promised.
