CENTRIFUGAL COMPRESSOR OIL SUMP DEMISTER APPARATUS

摘要

A refrigeration apparatus contains an oil sump (64) having an interior portion. A housing (74) is located, at least in part, within the oil sump interior. The housing (74) has at least one inlet (94) and at least one outlet. The inlet allows a vent gas stream to enter the housing and the outlet allows a vent gas stream to exit the housing. The inlet (94) may be an aperture extending circumferentially around the housing about one-third to one-half of the housing's circumference. Additionally, the inlet should be aboe the surface level (78) of any oil pool in the sump. A coalescing demister filter (90) is located within the housing between the inlet and the outlet. The housing may include a wall for sheltering the filter from agitated areas of the gearbox.
