- Abstract
In this paper it is evaluated the global performance of an one stage vapor compression cycle with superheating and no sub cooling, calculated as the ratio between refrigerating capacity and electrical power supplied to compressor (COP). It is stated that the superheating of the refrigerant in vapor state occurs inside the refrigerant space. This phenomenon is spontaneous and useful for the protection of the compressor. Since the ban of Hydrochlorofluorocarbons (HCFCs), Hydrofluorocarbons (HFCs) are used as alternative, one of the most visible in marine refrigeration being the non ozone depleting R134a. But the environmental issue does not only include the ozone layer; there is also an increasing worry about the global warming potential due to greenhouse effect. This is why the objective of this work is oriented on the performance of an one stage vapor compression cycle working with R134a and two more refrigerants, having lower GWP. These are R290 and R152a. The analysis for specific conditions will reveal that even if R152a has higher GWP than R290, its COP is better than R134a and R290.
