DYMAN (GA: 101161930) is an ongoing EIC-Pathfinder project aiming to develop a new adsorption chiller design with new low-T absorbents and adsorption heat exchangers, that are dynamically managed in data centres. It started in July 2024 and will continue for 36 months. The current DYMAN consortium consists of 10 entities (6 SMEs, 1 public university, 1 RTO and 2 non-profit organisations), from 4 different EU countries. Ekodenge (EKO) from Türkiye, who has successfully collaborated with some partners in the consortium and who develops SW services aiming to enhance the novel solutions of DYMAN, has proposed to collaborate with the consortium, which has been shared with the scope of actions and EKO’s possible involvement has been approved by the consortium in September 2024. DYMAN is developing new cooling generating technologies, materials to improve the cooling efficiency of data centres. With this hop-on proposal, EKO will develop digital tools for the enhancement of management & monitoring of cooling systems while addressing the unique requirements of cooling technologies and data centres: 1) dynamic Digital Product Passports (DPPs) for cooling technology developers that enables EU market compliance, life cycle traceability, and exchange of product information. 2) digital twin and DPP-linked Digital Building Logbooks (DBLs) for data centres which is a centralized repository for data on energy performance, sustainability metrics, used materials and components. This proof-of-concept application will contribute to EKO’s international visibility in competitive sustainability/ circular economy markets and will enable Türkiye to advance in the EU R&I environment. In addition to 5 existing specific objectives of DYMAN project, this Hop-On project addresses: - A new specific objective (SO): Development of interoperable, dynamic digital tools (DPPs and DBLs) for enhanced management / tracking of DYMAN cooling technologies and HPCs - 2 sub-objective supporting existing SO

DYMAN targets the development of a completely new design of adsorption chillers based on the following innovations (1) New low-temperature adsorbents achieving high capacities at very low driving temperatures below 50 °C. (2) New type of adsorption heat exchangers made of 3D printed structures integrating the adsorption material into a porous structure, which reduces the internal thermal resistances and improvement of heat transfer by two-phase flow, enhancing the heat transfer rate and reducing the internal electricity consumption of the unit. Additionally the project aims to develop at second core concept to further develop an existing two-phase cooling system, for high-performance computing servers to handle thermal loads more efficiently from next-generation processors. Goals include increasing cooling capacities for processors generating high heat fluxes like the Nvidia H100 chip which produces 70 W/cm2. An additional objective is to recover 50% of waste heat from processors to generate additional cooling power through a sorption heat pump. Combining two-phase cooling directly with heat-powered cooling could significantly improve efficiency over conventional air or water-based cooling methods alone. The objective here is to 1)further develop the present two-phase cooling system to work in an efficient way in combination with the sorption heat pump (concept 1) 2) Development of new evaporator with new advanced surfaces for high heat transfer coefficients (3) Development of new condenser integrated with the heat adsorber of sorption heat pump. This is a crucial component that can improve the efficiency of the whole integrated system to recovery up to 50% of rejected heat. Furthermore, the cooling data center management is a complex engineering system with interactions with different components of the data centers. So, DYMAN proposes a new way of active management of the data center integrating the cooling system as part of the optimization of processor management

Rail freight transportation is a system service where a multitude of players, participants and systems providers bear a high degree of responsibility for its attractiveness and performance. It shows high efficiency as transportation means, in terms of land use and energy consumption and low greenhouse gas emissions. However rail’s market share of freight transportation and its economic efficiency continues to be limited. Aimed at overcoming such uncertainty, this project addresses one of the most important key resources for further developing rail freight transportation: the optimization of the performance of the rail freight wagon. The continuous pressure on environmental issues and energy efficient transport is forcing the rail transportation sector to enhance the rail logistics services and to incorporate innovative solutions to improve load capacity to keep the “best-in-class” position and, therefore, acquiring a much privileged position beyond alternative terrestrial transport source, as truck transportation. Thus, aimed at optimizing rail freight transportation, the main objective of this project is to holistically address the aspects that may improve freight wagon performance: enhanced logistics, improved multimodal operative, higher load capacity, optimized filling/emptying time and flexibility to transport multi-products. This project aims to achieve such optimization by combining industrial expertise on the freight wagon design and construction, advanced materials for lightweight construction and logistics with the research capabilities to incorporate innovation solutions and optimize material performance.

The purpose of HYCOOL-IT is to develop a set of processes supported by both digital and technical equipment innovative solutions for an efficient and reliable development of IT Server Rooms for advanced tertiary buildings, with a special focus on its replicability through standardisation. In parallel, a highly innovative Rack-integrated adsorption chiller for waste-heat powered server cooling is developed and optimized to carry out efficient liquid cooling of IT servers and, simultaneously, provide cooling to the server room itself in a compact, self-contained, and cost-effective way. The Building Digital Twin Environment (BDTE) will be developed as a PaaS with their specific Web API communication microservices to connect specific tools to support planning and design assessment, commissioning and performance evaluation processes including advanced technical equipment solutions digitalized through as BDT SimBOTs (interactive simulators) in the ICT Ecosystem to enable a more effective integration and operation of these advanced server rooms within the whole buildings. Moreover, SimBOTS pave the way for the future prescription of the innovative technical equipment proposed in the project. In addition, existing rooms can be mirrored and enhanced with the usage of BDT Environments to generate improved baselines and forecasting to support designers in the design phase, choosing the best design option and for maintenance engineers to enable performance contracting to realise the KPI’s. All Methodology and Software solutions will be tested and validated in one of the POLIMI Campus Building undergoing renovation of campus server room as a representative TRL 5 Living Lab, whereas the innovative Rack-integrated adsorption chiller for waste-heat powered server cooling will be tested in a dedicated calorimetric laboratory as TRL 4 testing environment.
