0.1 to 0.5 h.p. per ton of refrigeration

0.5 to 0.8 h.p. per ton of refrigeration

1 to 2 h.p. per ton of refrigeration

2 to 5 h.p. per ton of refrigeration

lowers evaporation temperature

increases power required per ton of refrigeration

lowers compressor capacity because vapour is lighter

all of the above.
