One-dimensional modelling of sensible heat storage tanks with immersed helical coil heat exchangers: A critical review

Original language description

Sensible thermal storage tanks with immersed heat exchangers play a pivotal role in energy storage and exchange within a system, particularly when coupled with solar thermal collectors or heat pumps. Therefore, the optimization of the tank-exchanger assembly design and operation via modelling is of utmost importance in enhancing the performance and efficiency of these systems. This paper presents a critical review of onedimensional modelling approaches for short-term sensible storage tanks equipped with immersed helical coil heat exchangers, primarily focusing on their application in solar thermal and heat pump systems. The purpose of the review is to identify the limitations, gaps, and challenges in the existing modelling methodologies. A comprehensive literature review and comparative analysis were employed to gather information about the topic and to critically evaluate and compare different studies and approaches within the field, considering their methodologies, findings, strengths, and weaknesses. The review is structured into four main sections, starting with an examination of storage-exchanger assembly configurations discussed from a modelling standpoint, followed by an overview of the fundamental principles and limitations of one-dimensional models, a critical review of contemporary methodologies to determine the overall heat transfer coefficient of immersed helical coil heat exchangers, and a comprehensive survey of simulation models that implement these methodologies. The main issue that has been identified is the absence of up-to-date correlations and empirical coefficients for onedimensional modelling of tank-exchanger assemblies. In conclusion, this critical review highlights the need for further comprehensive research efforts to establish accurate correlations and empirical coefficients that can be used to effectively model storage tanks with immersed helical coil heat exchangers.
