    3 During compressor shutdown, gr avity , thermal act ion and refrigerant absorption can result in a re frigerant and oil mixture in compressor crankcase. Gr avity flow can be preve nted by the use of recommende d loops, but therm al action a nd t he absorp- tion of refrigerant by lubricating oil cannot be prevented by piping design. For the above r ...
