- •
Size of droplets departing from radiant cooling ceilings was studied experimentally.
- •
Radii of coalescence-induced jumping condensate range from 100 μm to 300 μm.
- •
Evaporation of droplets dripping from radiant ceiling to human skin can be neglected.
- •
Human perception of fallen droplets was studied via a psychological experiment.
- •
Sensory threshold size for fallen droplets was found to be a radius of 325 μm.
