Abstract

1479451 Rotary positive-displacement fluidmachines SVENSKA ROTOR MASKINER AB 18 June 1974 [18 June 1973] 28742/73 Heading F1F In a method of operating a refrigerant compressor of the oil-injection meshing-screw type the kinematic viscosity of the injected oil is not less than the value given by the equation (in centistokes) at 50C, where p 1 is the discharge pressure in kp/cm2, u is the male-rotor tip-speed in m/sec, e is the natural logarithm base, and c is equal to the refrigerant being of the hydrocarbon or halocarbon compound type. This method is said to improve the performance at low rotor-speeds. Preferably, the capacitivity ratio of the oil and refrigerant is in accordance with the Formula:- (In#r gas -In#r oil ) # 1, where In means the natural logarithm.
