Experimental characterization of an innovative hybrid thermal-electric chiller for industrial cooling and refrigeration application

The energy demand of industries accounts for about 30–35% world yearly consumption, a relevant percentage is due to the need heating and cooling demand. Solar technologies can be integrated in industrial processes reduce fossil fuels consumption as well related greenhouse gas emissions. This paper reports experimental analysis novel hybrid sorption-compression chiller refrigeration purposes cascade layout, which uses silica gel/water sorption cycle low Global Warming Potential (GWP) refrigerant, i.e. propylene compression cycle. results highlighted flexibility system terms performances operating conditions, these were compared theoretical it was found out that electricity savings from 15% 25% achieved when using over one with same capacity. converted performance maps processed statistical model, order get simplified expression determining overall through variables could measured by final user, such temperatures. Optimization strategies identified further enhancement chiller, reduction controlling intermediate temperature (evaporation chiller) management use variable speed pumps all circuits parasitic especially at part loads.
