Abstract (EN): This work has as main objective an analysis of the validity of the implementation of a flooded evaporator in a vapor compression refrigerant cycle, the working fluid being the R134a. To achieve this goal, it was used a simulation software, the Pack Calculation Pro. A comparison of the annual energy consumption of the refrigeration system with a flooded evaporator was carried out having as reference the same system with a dry evaporator and working in different situations. In this study, the advantages and disadvantages of using the two types of evaporators, the flooded and dry one, having the system used for situations equal cooling capacity and the possible presence of overheating for the dry evaporator and the presence of the pump in the flooded evaporator was analyzed. It was concluded that the advantage in the implementation of flooded evaporator is directly proportional to the degree of overheating at the exit of the dry evaporator. Also an economic analysis were carried out.
