EER = Cooling Capacity (BTU/hr) / Power Input (Watts)
Guida passo passo
- 1Check equipment nameplate for BTU and wattage
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Esempi risolti
Ingresso
12,000 BTU AC, 1200W power input
Risultato
EER = 12000/1200 = 10 (SEER translates to seasonal EER)
Errori comuni da evitare
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
