1.5HP (12,000 BTU/hr): This indicates the cooling capacity. 1.5 Horsepower or 12,000 BTU (British Thermal Units) is suitable for medium-sized spaces, typically up to \(18–24 \text{ m}^2\) (roughly \(200–250 \text{ sq ft}\)), such as bedrooms, living rooms, or small offices.[SFACS12INK]:SFAC: Scanfrost Air Conditioner.S: Split unit.12: 12,000 BTU (1.5HP).INK: Indicates Inverter technology + R32 Eco-friendly refrigerant.Inverter Technology (INK): Unlike traditional ACs that constantly switch on/off, an inverter AC adjusts its compressor speed to maintain a consistent temperature, which reduces electricity consumption significantly.9kg / 9,000 BTU Variant? Note: The 1.5HP Model is usually 12,000 BTU. If you see "9" in a Scanfrost model name, it often refers to the 1HP (9,000 BTU) SFACS09INK model.
