The design of oil separators is standardized and is characterized by low oil carryover and reduced oil consumption.
There are two types of installations:
Vertical installation of oil separator
The coolant-oil mix is led to the bottom of the oil separator. This type of oil separators has two chambers, where the three-phase separation of the oil from the refrigerant is carried out.
Horizontal installation of oil separator
The coolant-oil mix is inserted into the first part of the oil separator. In this case the oil separators have three chambers. The first chamber uses gravity separation. The hot gas passes through the melter as it flows out of the first chamber into the second chamber. The separated oil is collected in another chamber. Both chambers work simultaneously as an oil collector.
