What Are the Core Design Parameters for Mini Split Heat Pumps?
Dimensional Considerations for Indoor and Outdoor Units
Mini split heat pump design demands meticulous attention to dimensional specifications. Typical configurations include:
Indoor Unit Dimensions
- High-wall Mounted: 12x30x10 inches
- Weight Range: 20-40 pounds
- Optimal Placement: Near ceiling for maximum airflow distribution
Outdoor Unit Specifications
- Typical Dimensions: 12x30x21 to 32x40x16 inches
- Weight Range: 50-150 pounds
- Recommended Placement: Well-ventilated area with minimum 3-foot clearance
How Do You Calculate Proper Sizing for Mini Split Systems?
Room Size and BTU Requirements
| Room Size (sq. ft.) | Recommended BTU Capacity |
|---|---|
| Up to 250 | 6,000 BTU |
| 350-400 | 9,000 BTU |
| 450-550 | 12,000 BTU |
| 700-1,000 | 18,000 BTU |
| 1,500+ | 24,000 BTU |
Factors Influencing Sizing
- Insulation quality
