This equipment is for the oil separator of a screw compressor. Calculation of the volume of vapor in the oil separator constitutes the bulk of the ammonia in a compressor package. All dimensions are assumed to be internal to the oil separator. Total volume calculated is the empty separator, while the displayed separator volume is the total volume with the oil volume subtracted.
The Head Ratio is the ratio of the separator diameter to its head diameter (twice the individual head dimension). Ellipsoidal heads with a ratio of 2:1 are the most common.
The Separator Length includes the shell length and both heads. The length of a 2:1 ellipsoidal head is ½ the diameter.
If the entered temperature is below the saturation temperature of the pressure provided, the density of saturated vapor at the given pressure is used.
Reciprocating compressors do not contain significant amounts of refrigerant, however they can be added as a user specified unit if desired.
