Air conditioner capacity calculator
Pick the room type — the rest (insulation, sun, heat gains) is filled in automatically. You can refine any of it. This is a rough guide; a specialist picks the exact model.
Method: Q = Q₁ + Q₂ + Q₃. Q₁ — heat gain through the envelope (volume × 30–44 W/m³, adjusted for insulation, sun and top floor), Q₂ — people (0.10–0.28 kW each), Q₃ — equipment and lighting. A 10% margin is added.
