- Evaporator
- Compressor
- Condenser
- Expansion Valve

THE MOST IMPORTANT LOSSES IN REFRIGERATION SYSTEMS
In a refrigeration system, which contains evaporator, compressor, condenser and evaporation valve, the most important losses can be observed in compressors. Besides, through pipes and condenser and evaporator can be the sources of losses in the system. The pressure losses through pipes can be ignored in small storage rooms. But in big ones and especially if you are performing the project calculations you have to take these losses into consideration.
