Samsung AC052TN4DKC/EA-18BTU Cassette Inverter WindFree

4‑Way WindFree™ Cassette Design — Ceiling‑mounted cassette delivers wind‑free cooling through tens of thousands of micro‑holes in all four directions—ensuring even, draft‑free airflow throughout the room 

Nominal Cooling Capacity ~17,000 BTU/h (~5 kW) — Rated cooling output: Min/Std/Max ≈ 3,410 / 17,000 / 20,470 BTU/h (~1.0–6.0 kW) to adapt to different load demands 

Digital Inverter Technology — Incorporates Samsung’s inverter compressor for efficient, precise temperature control, reduced power cycling, and long-term energy savings 

High Energy Efficiency (EER ~3.55 W/W) — Delivers strong energy performance per unit input power at nominal cooling capacity 

Quiet Operation — Engineered for low sound levels in indoor settings thanks to optimized fan blades and balanced airflow from all four cassette directions 

Uniform Air Distribution — Four-direction airflow ensures consistent room temperature without cold spots or strong directional drafts 

Motion Detect Sensor (Optional on Some Markets) — Available on variants like AC052TXADKC/EA, it adjusts cooling based on occupancy to enhance comfort and efficiency 

Slim Cassette Profile — Indoor unit net dimensions around 880 × 638 × 310 mm and ~40 kg weight—compact for drop‑ceiling installations 

R410A Refrigerant & Big-Blade Fan — Uses R410A refrigerant; large fan blades produce broader air volume with reduced noise and flutter 

Energy‑Saving Mode & Smart Features — Offers two‑step cooling control and integrated inverter boost with smart operation modes for optimal comfort and power savings
