The Samsung AC140RN4DKG is a 4-way ceiling cassette indoor unit designed to provide efficient temperature control for larger spaces through both cooling and heating functions. It utilizes WindFree™ technology, which disperses air through thousands of micro holes to maintain a comfortable environment without the discomfort of direct cold drafts. This system offers a maximum cooling capacity of 15.5 kW and a heating capacity of 18 kW, using R-32 refrigerant to balance performance with environmental considerations. Measuring 84 cm in width, the white unit integrates discreetly into the ceiling and features Big Blade technology to extend the reach of the airflow across the room. You can customize the environment using four different operation modes and adjustable air flow directions, while the maximum noise level is kept at 45 dB to ensure the space remains quiet. For those seeking further efficiency, the unit supports an optional Motion Detect Sensor to optimize energy use based on occupancy, potentially reducing energy consumption by up to 55% when used with WindFree cooling and a compatible outdoor unit.
