Summary
Large-temperature-lift heat pumps for simultaneous heating and cooling (HP4SHC) have a great potential for the decarbonization of dairy processing industries. In this paper, the performance of HP4SHC cycles using natural refrigerants is simulated for a range of typical heating and cooling temperatures from 20 °C to 150 °C for dairy product production by evaporation, pasteurization, sterilization, and UHT heating, ≤ 7 °C for fluid milk chilling and dairy product refrigerated storage. The performance of HP4SHC cycles is also compared to a business-as-usual scenario in the dairy industry (i.e., natural gas-fired boiler and electrically-driven compression chiller). Further, the cycle's performance is contrasted with (add-on) heat pumps used to upgrade waste heat from the refrigeration system. As a result, HP4SHC reduces energy consumption, increasing the dairy plant's competitiveness and mitigating carbon emissions. Thus, HP4SHC plays a key role in a low-carbon future in the dairy industry and meeting long-term sustainability targets.
