Abstract
A lubricant separator includes a shell, a vapor inlet located at a first end of the shell to admit a flow of refrigerant and lubricant into the lubricant separator and a muffler positioned in the shell. The muffler includes a first perforated pipe extending along a longitudinal axis of the shell from the vapor inlet, a second perforated pipe radially spaced from the first perforated pipe, an absorption material layer positioned radially outboard of the second perforated pipe, and a lubricant-permeable liner positioned radially between the second perforated pipe and the absorption material layer. The lubricant-permeable liner allows for acoustic wave transmission from the second perforated pipe to the absorption material layer.
