The general rule for rating refrigeration systems (excepting for CO₂ system) is to approximate following h.p. per ton of refrigeration

0.1 to 0.5 h.p. per ton of refrigeration
1 to 2 h.p. per ton of refrigeration
0.5 to 0.8 h.p. per ton of refrigeration
2 to 5 h.p. per ton of refrigeration

Refrigeration and Air Conditioning
The bypass factor, in case of sensible cooling of air, is given by (where td₁ = Dry bulb temperature of air entering the cooling coil, td₂ = Dry bulb temperature of air leaving the cooling coil, and td₃ = Dry bulb temperature of the cooling coil)

(td₃ -td₂)/( td₁ -td₃)
(td₃ -td₁)/( td₂ -td₃)
(td₁ -td₃)/( td₂ -td₃)
(td₂ -td₃)/( td₁ -td₃)
