Radiant Cooling For Users’ Comfort Cooling
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.
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.

The Principle of Radiant Cooling
Heat is absorbed by the breeze on the skin, resulting in a cool feeling.
Heat is absorbed by the cool surrounding walls and ceiling, resulting in
a cool feeling.
The breeze directly contacts the body for cooling.
The breeze cools the walls and ceiling, which absorb the body heat.
Cools Gently and Evenly
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.
Test conditions: Measured in stable operation at 25˚C cooling with fan speed set at "HI."
Radiant Cooling Removes Heat From Ceiling And Walls
SKY Series makes people comfortable because the radiant heat from ceiling is less.
Measured in stable operation at 25˚C cooling with fan speed set at "MEDIUM."
The actual average room temperature is the same.
The globe temperature is about 0.8˚C higher (=About 1.1˚C higher in terms of how people feel comfortable). The globe temperature is a composite temperature used to estimate the effect of temperature, humidity, and solar radiation on humans.
The Benefits of Radiant Cooling
SKYWING angles upwards to cool without direct airflow, thus preventing overcooling and maintains skin moisture.
Measured in stable operation at 25˚C cooling with fan speed set at "HI."
