Refrigeration and Air Conditioning 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 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 ANSWER DOWNLOAD EXAMIANS APP
