Radiant Cooling

Discover Natural All-Round Cooling

RADIANT COOLING is inspired by caves, where the cool surfaces
create an all-round cooling effect. After reaching the set temperature,
SKYWING angles upwards to direct airflow towards ceiling and walls to
remove the heat trapped in these surfaces for an overall cool environment.

How RADIANT COOLING works

How RADIANT COOLING works:

Cool air is directed towards the ceiling.

Cool air spreads evenly throughout the room.

Heat trapped in ceiling and walls is removed.

Room is evenly cooled down.

RADIANT COOLING AIRFLOW ASSESSMENT

AIRFLOW SMOKE TEST

BOTTOM AIR INTAKE

AIRFLOW SMOKE TEST

Instead of blowing cold air directly onto people, SKYWING directs the airflow upwards to cool the ceiling and walls.

BOTTOM AIR INTAKE

Hot air is drawn in from the bottom, and cool air is discharged from the top to facilitate the even distribution of cool air.

RADIANT COOLING
FOR USERS’ COMFORT

Inspired by the cooling effect of caves, Doctor Naoshi Kakitsuba investigated the benefits of RADIANT COOLING. He found that this gentler and more even cooling method results in a greater feeling of comfort and wellbeing.

Conventional air conditioners are built to blow cold air downwards and directly at people to cool them instantly. However, when in direct contact with cold air for too long, some people experience discomfort and dry skin.

SKY SERIES
COOLS GENTLY AND EVENTLY

The SKY Series makes the room evenly cool, even though no airflow feeling.
The cooling system of SKY Series gives comfort based on the principle of RADIANT COOLING.

The temperature in all areas of the room
can be evenly set at a comfortable level.

Comfortable in living space with no wind
