This research group have been working on industrial, commercial and residential refrigeration systems for decades. The growing energy demand for refrigeration in different applications and its consequent share of on the global energy demand have risen much interest to find new technical solutions to improve the energy efficiency. Thus cascade cycle and air cycle has been studied as efficient means to reach low temperatures (below -40°C). Furthermore an activity to monitor the present technological development in industries of the refrigeration sector is ongoing in order to determine the reference baseline and to suggest possible improvements. Moreover heat pump systems are studied and optimized in the lab as very efficient and promising devices for HVAC plant. It is also in place an activity about new refrigerants at low environmental impact both from a technical and regulation perspective.
In particular thermodynamic analysis of different plants and their application are performed:
• Experimental and simulation analysis of heat pumps and their components
• Experimental and simulation analysis of absorption chiller
• Experimental and simulation analysis of cascade cycle and air cycle for low temperature refrigeration.
• New refrigerants and their impact on the technological and energy scenario of the refrigeration sector.
The activities are carried out in the Refrigeration Laboratory.
