Learning Objectives / Experiments
- design and function of a refrigeration system with
two-stage compression and injection intercooling
- effect of the inlet temperature at the HP compressor on the efficiency of the compression
* with intercooling
* without intercooling
- effect of the additional refrigerant intercooling
- distribution of the compressor pressure ratios
- represent and understand the refrigeration cycle process in the log p-h diagram
