CAC - World-class energy efficiency
Maintain optimal comfort and control with energy and
cost-efficient technologies
Featuring a suite of energy-optimizing technologies,
Samsung CAC Single delivers top-class energy efficiency
to support business in saving costs and the environment.
Quick, efficient heating and cooling
Smart inverter technology offers powerful, quick cooling
and heating with minimal electricity consumption, which
means real cost savings and less energy waste.
Up to 50 percent less energy use
After reaching changes its operation mode to economical.
By avoiding inefficient and frequent switching on and off of
the compressor, the digital inverter saves up to 50percent
in energy consumption compared to non-inverter air
conditioners.

Wind-Free Cooling with Micro holes
•The Wind-Free Air conditioner pushes air out through
15,000 micro holes in the panel, producing a dispersed
and gentle flow of air actually defined as “still air” and
the key here is all of those holes create a still, cooled
air flow that infiltrates the room gently and softly.
※ Still Air condition : According to ASHRAE, If velocity
of wind is lower than 0.15m/s, People can not detect
wind. And they define that condition is “Still Air”

CAC Single - Superior performance
Stabilize the atmosphere with broad temperature
allowance and control
Samsung is dedicated to supporting comfortable living
and working environments based on the strength of
its technologies. With a single unit, CAC Single delivers
reliable comfort and control over multiple areas to ensure
a pleasant atmosphere in any climate.
Wide temperature performance
No matter how extreme the temperature, the high-
performing CAC Single can handle the condition-
without the need for an additional unit. Featuring a wide
