HVAC metrics:
SEER = (1 × EER100% + 42 × EER75% + 45 × EER50% + 12 × EER250%)/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 Δh (std. air)
Sensible Heat (BTU/hr) = 1.1 x CFM x Δt (std. air)
Latent Heat (BTU/hr) = 0.69 x CFM x Δgr. (std. air)
1 HP = 746 Watts
1 kW = 3413 BTU
