SR2023 oil return in refrigeration systems
Learning Objectives / Experiments
- fundamentals of the oil return in refrigeration systems
- effect of the rising pipe diameter on the oil transport
- effect of partial and full load operation on the oil transport
- principle of operation of a double rising pipe
- separate or parallel operation of the compressors
Specification
[1] investigation of the oil return to the compressor in
refrigeration circuits with oil soluble in refrigerant
