Objectives and methodology The goal of this thesis is to identify one or more alternative refrigerants to R410A in a specific domestic heat pump, by evaluation of its overall environmental impact by the TEWI factor. This main task can be divided in different sub goals: - Selection of alternative refrigerants - Validation of the elaborated model - Evaluation of performance of refrigerants in the model - Elaboration of recommendations -3-
