Abstract: A refrigerating apparatus comprising a refrigerating cycle into which a screw compressor is incorporated, and a liquid super cooler connected on the way of a liquid pipe of said refrigerating cycle, said screw compressor having a gas intake and/or liquid coolant injection opening which is located at a position where the screw blades of the screw compressor have at least partially compressed the gas in the screw compressor. The position of the gas intake provided in the screw compressor and intended to pass the gas from the liquid super cooler into the screw compressor is limited under such a condition thatV.sub.i = 1.0 .about. 4.5In which ##EQU1## V.sub.L represents the theoretically maximum screw space volume (m.sup.3 /h) in the screw compressor and V.sub.H represents the screw space volume (m.sup.3 /h) at the position of the gas intake.
