Periodic Reporting for period 1 - HYCOOL-IT (HYbrid COOLing & management for IT infrastructures)
Période du rapport: 2023-12-01 au 2025-05-31
• GO1: Unfold a new methodology and ICT tools based on Building Digital Twins Environments to:
- Optimised Planning evaluation, Design and Construction phases by the usage of SIMBots as Building Digital Twin libraries.
- Reduced gap between design and operation simulations by a Simulation Model Tracking System along components commissioning.
- Generate a dedicated Model Predictive Control based on the coupling of monitoring & simulation (Software in the Loop - SiL -)
Such methodology and ICT tools will be completely replicable in dedicated IT Rooms and, more in general, in buildings and will be able to communicate with both the Data Centre Infrastructure Management (DCIM) at Server Room Level and the Energy Management Systems (EMS) at the building level.
• GO2: Develop a cost-effective plug and play Hybrid System of Rack-integrated adsorption chillers for waste-heat powered server cooling.
• GO3: Generate strategies to effectively replicate both hardware and software solutions alone and as a coupled solution, with special focus on standardisation in relevant areas of influence (product design & certification in cooling equipment, procurement and commissioning, control equipment, buildings energy performance simulation and monitoring during O&M).
In WP2, communication protocols and interoperability requirements necessary for seamless integration of Building Control Systems (BCS) in advanced IT server room environments have been analysed and defined. The ICT architecture of the Building Digital Twin Environment has been developed, including simulation tools, BIM representations of the server room and the cooling equipment, monitoring of real-time data, and using Software in the Loop -based Model Predicting Control algorithm. The architecture for the alpha testing of the software solutions has been also developed.
In WP3, a methodology to guide interventions in thermal management optimization of server rooms, including the definition of performance metrics, area of interventions, type of intervention, impact assessment on performance metrics, and monitoring requirements to verify and maintain energy performance during system operation through Digital Twin solutions, have been defined. Moreover, schematics for the integration of Server Rooms waste heat recovery in buildings and district heating networks have been produced, along with a simulation model for fast assessment of related energy, economic and financial benefits. A basic library of simulation components consisting of generic SIMBOTS for IT Server Room has been developed, along with the strategy to assess future scenarios using simulation models under the Building Digital Twin Environment.
In WP4, a numerical model of the innovative rack-integrated adsorption chiller was developed and implemented in the commercial software Dymola (Modelica). The proof-of-concept (PoC) of the rack-integrated adsorption chiller (RIAC) has been manufactured, and preliminary experimental activities have been carried out.
In WP5, the digital twin platform as a service has been deployed for the Bovisa Campus pilot site. The platform has connected existing devices for control and monitoring by using a VPN connection. Additionally, the design and bill of quantities for the renovation of the Campus server room have been completed, which includes waste heat recovery in the associated university building through a dedicated heat pump. Tender documentation has been prepared, and the tender has been awarded, allowing construction works to commence.
1. Methodology for the creation and maintenance of IT Server Rooms DTs:
- Development of Methodology framework and related Use Cases KPI definitions: The development and validation of the methodology are expected to reduce the preparation time of adapting simulation models along the engineering project up to 20% which will lead towards a much more accurate prediction, with less than 20% gap with Monitoring during O&M, as well as generating a bidirectional communication in between the server room DCIM and the building BEM.
2. ICT Ecosystem and Orchestration:
- HYCOOL-IT federated ICT tool as a BDT Environment: The integration of Contextual and Dynaic real data (including historical datasets) within related thermal Simulation Models within the environment will raise the number of stakeholders reaching a Single Source of Truth leading to in field professionals time reduction as well as a steady Increment of simulation models numbers and accuracy during design phase until reaching a truly simulation model calibration.
- Simulation Model Tracking System (SMTS): SMTS module implemented as a tool of the PaaS BDTE
- SiL based Mode Predictive Control (MPC): MPC Service implementation as part of the PaaS BDTE
3. Technical Equipment:
