标准制冷量参考:
1匹 ≈ 2500W | 1.5匹 ≈ 3500W | 2匹 ≈ 5000W | 3匹 ≈ 7200W
一般住宅制冷量需求: 150-220W/m² (根据条件调整)
| 匹数 | 制冷量 (W) | 适用面积 (m²) | 类型参考 |
|---|---|---|---|
| 1匹 | 2500 | 10-15 | 壁挂式 |
| 1.25匹 | 3200 | 12-18 | 壁挂式 |
| 1.5匹 | 3500 | 15-22 | 壁挂式 |
| 2匹 | 5000 | 22-32 | 壁挂/柜式 |
| 2.5匹 | 6000 | 28-40 | 柜式 |
| 3匹 | 7200 | 35-50 | 柜式 |
| 5匹 | 12000 | 55-80 | 柜式/中央 |

| Horsepower definition | 1 hp ≈ 735 W input power, ≈2500 W cooling capacity (3500 W is called 1.5 hp) | GB/T 7725-2022 Room Air Conditioners |
| Cooling load per area | Ordinary housing 120–150 W/m²; west-facing or top floor +10%–20%; higher end for crowded living rooms | GB 50736-2012 empirical load estimation |
| Ceiling height correction | For ceilings above 3 m correct by volume: Q ≈ per-area load × (height / 2.8) | Empirical load calculation correction |
| EER / COP | Fixed-speed EER = cooling ÷ input power; inverter rated by SEER/APF (grades 1–5) | GB 21455-2019 Minimum Allowable Values and Energy Efficiency Grades for Room Air Conditioners |
| Sizing example | 15 m² bedroom: 15 × 130 ≈ 2000 W → choose 1 hp (2500 W) for margin | GB 50736-2012 |
