Central Air Conditioner SEER2 vs SEER Energy Consumption & Cooling Degree Day (CDD) Benchmark Matrix
Steady-state electrical power draw (Watts at 95°F), annual kilowatt-hour operational demands, and DOE M1 static pressure metrics across 1.5 to 5.0 nominal cooling tons referencing AHRI 210/240 rating conditions.
1. Abstract & Dataset Scope
Provides a source-informed benchmark matrix evaluating energy consumption, external static pressure adjustments (0.50 in. w.g. under DOE 10 CFR Part 430 Appendix M1 vs 0.10–0.20 in. w.g. legacy SEER), and regional annual kilowatt-hour demand across 1.5-ton to 5.0-ton residential central air conditioning split systems.
2. Technical Methodology & Benchmark Formulation
Calculated using DOE 10 CFR Part 430 Appendix M1 rating procedures and AHRI 210/240 performance standards, accounting for blower fan wattage deratings at 0.50 inches water column external static pressure across single-stage, two-stage, and variable-speed systems.
