Rerversible Heat Pump + Air Conditioning + Refrigeration with 2 Condensers and 2 Evaporators (Water/Air)

The unit has as aim introduce the student to the study of the heat pumps, air conditioning and refrigeration, as well as the analysis and determination of the operation typical parameters of the unit depending on the two types of fluids used in the processes of evaporation and condensation (air and water).
