Progetto ZHENIT - D.2.4: Experimental validation under lab-controlled

ZHENIT project main objective is to promote WHR as key and “ready-to-scale up” solutions to greatly contribute to 2030 IMO/EU decarbonization targets with the aim to validate innovative WHR solutions at various temperature levels, optimizing its integration and performance. Some of these WHR technologies considered in the project are sorption desalination and cooling unit, isobaric expansion engine and ORC-ejector integrated heat pump. In this report, only information related to sorption desalination and cooling unit, isobaric expansion engine and ORC-ejector integrated heat pump manufacturing and experimental testing is included. Detailed information on the sorption desalination and cooling system design is available in D2.1 “Development and detailed design of the sorption desalination and cooling unit“, the Isobaric Expansion Engine (IEE) design in D2.2 “Development and detailed design of the Isobaric Engine” and ORC-ejector design in D2.3 “Optimised design of the ORCejector heat pump prototype”. The two key objectitives of the activities reported are the following : 1) based on the detailed designs of the prototypes to be manufactured and 2) conduct an experimental validation campaign under labscale controlled conditions of each tecnology in order to characterize the systems and provide assurances to WP4 “Validation Campaign”. Chapter two of this document provides a detailed description of the steps undertaken in the manufacturing of the sorption desalination and cooling unit, along with the results of the validation campaign. Section three focuses on the manufacturing and validation campaign under lab-conditions of the isobaric expansion engine conducted in TECNALIA´s laboratory. Finally, chapter 4 presents the progress achived in the construction of the ORC integrated with ejector and the results obtained from its validation campaign.
