Abstract (EN): — The main objective of this work is a technical and economic analysis of a flooded evaporator in a vapour compression refrigerant cycle using R134a as working fluid. To achieve this goal, it was used a simulation software, the Pack Calculation Pro 4.2. 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. In this study are analysed the advantages and disadvantages of using the two types of evaporators, the flooded and dry one, in situations of presence of overheating for the dry evaporator and the presence of the pump in the flooded evaporator. 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
