Development and experimental testing of a flexible, fully automated ORC-ejector-integrated heat pump micro-scale prototype for the production of heating, cooling and electricity. The prototype is driven by vessel engine waste heat (>90 deg°C) and is based on the combination of an Organic Rankine Cycle, an ejector cooling cycle and a vapor compression cooling cycle capable of multiple operating modes. Development of a dynamic modelling platform for the techno-economic optimization of the design and sizing of ZHENIT technologies (latent thermal energy storage, isobaric expansion engine, ORC and sorption-desalination chiller) based on typical vessel engine waste heat profiles of cargo and cruise vessels.
