Question about LG BG8000ER Air Conditioner
What is the Procedure of Heat Load Calculation
Plz define the Right Formula
Here are a few ways to calculate your BTU's.
Get ready to use that algebra you thought you'd never use.
1 Ton = 12000 BTU's
400cubic feet per minute (CFM) = 1 Ton on standard ac units (300 is an absolute minnimum)
BTU's air heat = difference in temp. ( ∆T ) x 1.08 x CFM
∆T = BTU's / (1.08 x CFM)
i.e. 65◦F entering your unit and 93◦F air leaving on a 12000BTU unit.
∆T = 28
CFM = 400
28 x 1.08 x 400 = 12096BTU's
Electric heat calculations.
BTU's = KW (killowatts) x 3413
Watts = Volts x Amps (single Phase) Most Homes))
Watts = Volts x Amps x Phase (this is for three phase units.)three wires and a ground))
120 volts 30 amps single phase (common)
120 x 30.0 x 1 = 3600 or 3.6KW 3.6 x 3413 = 12286BTU's
