“…Current data-centre modelling programs focus on either data-centre room airflow management or cooling-system simulation, with models designed only for limited, specific applications [25]. More specifically, energy-modelling software has been developed for data-centre simulations such as Project CoolEmAll in March 2013 commissioned by the EU-designed to be the first data-centre simulation tool using a thermal airflow simulation and coupled workload [26].…”

This study examines the feasibility of utilising outside air for ‘free cooling’ in modular data centres through the implementation of an air-side economiser, as an alternative to traditional mechanical cooling systems. The objective is to offset the energy consumption associated with cooling by leveraging the natural cooling capacity of the ambient air. To investigate this potential, a 90-kW modular data centre is employed as the base case for model validation and analysis of energy reduction possibilities. The research employs dynamic thermal modelling techniques to assess the efficacy of the air-side economiser in four distinct climatic zones: Stockholm, Dubai, San Francisco, and Singapore, representing diverse worldwide climates. The model is meticulously calibrated and validated using power usage effectiveness (PUE) values obtained from the Open Compute Project. Simulation runs are conducted to evaluate the energy-reduction potential achievable with the air-side economiser compared to conventional mechanical air-conditioning systems. The results indicate significant energy reductions of up to 86% in moderate climates, while minimal reductions are observed in dry and hot climates. This comprehensive analysis offers valuable insights into the intricate relationship between modular data centres, their operational characteristics, and the viability of employing air-side economisers for free cooling and energy efficiency across different climatic conditions. The contribution of this publication to this field of science lies in its exploration of the practicality and energy-saving potential of air-side economisers in modular data centres. By utilising dynamic thermal modelling and empirical validation, this study provides evidence-based insights into the effectiveness of this cooling strategy, shedding light on its applicability in various climates. The findings contribute to the understanding of energy-efficient cooling solutions in data-centre design and operation, paving the way for more sustainable practices in the field.

“…Due to its significant importance, cooling optimization has been the subject of studies done within a number of research and development projects. One of them was CoolEmAll [274,299] which involved several authors of the current paper and investigated how cooling, heat transfer, IT infrastructure, and applications influence the overall energy and cooling efficiency of data centers. CoolEmAll provided advanced planning and optimization tools -SVD Toolkit (Simulation, Visualization and Decision support toolkit) enabling analysis and optimization of data center infrastructure in a holistic manner.…”

“…As noted in [27], the objective of the CoolEmAll project was to enable designers and operators of a data center to reduce its energy impact by combining the optimization of IT, cooling and workload management. For this purpose CoolEmAll investigated in a holistic approach on how cooling, heat transfer, IT infrastructure, and applicationworkloads influence overall cooling-and energy-efficiency of data centers, taking into account various aspects that traditionally have been considered separately.…”
