Core Technologies & Features
🤖 AI EcoMaster Technology
The Solunar EF-24RD1 doesn’t just react; it predicts. By analyzing multiple environmental factors every 30 seconds, the AI EcoMaster adjusts the compressor’s performance in real-time. This eliminates temperature swings (precision ±0.3°C) and ensures peak efficiency without manual adjustment.
🌬️ Ceiling Cooling & Carpet Heating
Avoid uncomfortable direct drafts. The 180° rotatable louver allows for “Ceiling Cooling,” where cold air glides along the ceiling before gently descending. In winter, “Carpet Heating” pushes warm air to the floor, allowing heat to rise naturally from your feet up.
🛡️ Hyper Grapfins™ (12x Corrosion Resistance)
The heat exchangers are protected by graphene-enhanced Hyper Grapfins. This ultra-dense coating provides 12x higher resistance to corrosion compared to standard blue fins, ensuring the unit thrives in salty coastal air or areas with high humidity.
🧼 56°C i-Clean Sterilization
Maintain a healthy indoor environment. The 4-phase i-Clean cycle freezes the evaporator to trap dust and then heats it to 56°C for 30–60 minutes to kill bacteria, mold, and viruses, ensuring only fresh air enters your room.
