HVAC metrics:

SEER = (1 ร— EER100% + 42 ร— EER75% + 45 ร— EER50% + 12 ร— EER25%)/100

EER = BTUcooling/W

HSPF = BTUheating/W

COP = Q (useful heat)/W (input work)

ACH = CFM x 60/Area x Heightceiling

Total Heat (BTU/hr.) = 4.5 x CFM x ฮ”h (std. air)

Sensible Heat (BTU/hr) = 1.1 x CFM x ฮ”t (std. air)

Latent Heat (BTU/hr) = 0.69 x CFM x ฮ”gr. (std. air)

1 HP = 746 Watts

1 kW = 3413 BTU
