Technological advancements in the utilization of renewable energy sources have unveiled potentials for increasing building energy efficiency. Integrating heat pump-based energy systems with thermal storages is a suitable option to meet the thermal requirements of modern buildings and exploiting the available renewable energy sources. However, how to size the main components of a heat pump-based energy system with the integration of short- and long-term storages is not yet well explored. Therefore, this study focused on the design and performance analyses of an integrated heating and cooling system consist of a heat pump, borehole long-term thermal storage, and hot water tank short-term thermal. Heat pump models were introduced as parametric models based on the producer data. The dynamic thermal model of the energy system was developed and analysed in MATLAB. Different combinations of heating and cooling loads were tested. Integration of cooling and heating systems was discussed through different operation strategies and challenges were addressed. The results of the parametric analysis identified the key parameters affecting the design of components and efficiency of the system. Moreover, the results showed that lower cooling to heating load ratio leads to an excessive reduction of the ground temperature and overall efficiency over the long-term operation.

“…They can be categorized considering the physical mechanism included in the process of heat storage, for example, sensible heat, thermochemical storage, and latent heat. Thermal energy storage of sensible heat relies on stored energy or the release that occurs when a specific substance differs its temperature under the exact final and initial chemical structure 20 . There are additional types of energy storage that comes under TES, for example, hot water, molten salt storages, which are briefly explained herein.…”

Global warming plays an increasing role in our world, as the share of renewable energy sources in the overall production of electricity has witnessed exponential growth over the past years. Consumer demands are required to be met at any moment at a feasible price. However, storing energy in hot and arid climate regions is a sensitive matter as it is critical to consider appropriate technologies to implement for avoiding unnecessary causalities caused by extreme temperatures. This study compares 13 different energy storage methods, namely; pumped hydro, compressed air, flywheels, hot water storage, molten salt, hydrogen, ammonia, lithium-ion battery, Zn-air battery, redox flow battery, fuel cells, supercapacitors, and superconducting magnetic storage to be implemented in hot arid regions in terms of water usage, energy density, location dependency, and temperature degradation. A survey was conducted based on prior criteria to compare all 13 energy storage methods. The study concluded that the highest rankings for energy storage techniques are obtained for; Zn-air battery, superconductors, and flywheels with overall rankings of 7.18, 6.73, and 6.61, respectively. In contrast, some of the rankings are very close to each other implying the potential application of several methods in hot climates.

“…The primary challenge is to create a set of methodologies to guide the process from description of the thermal process to defining TES geometry based on the requirements and constraints of thermal application. 32 Taking a broader view, TES systems are a part of a wider group of flexibility alternatives. Considering the growing number of factors which are increasing system complexity, there is still much room for the design of integrated energy systems, along with the advancement of streamlined building/ district modeling tools and system optimization techniques.…”

Recent research focuses on optimal design of thermal energy storage (TES) systems for various plants and processes, using advanced optimization techniques. There is a wide range of TES technologies for diverse thermal applications, each with unique technical and economic characteristics. Matching an application with the most suitable TES system remains challenging. This study proposes an eight‐step design methodology guiding the process from describing the thermal process to defining the most appropriate TES based on constraints and requirements. The steps include specifying the thermal process, system design parameters, storage characteristics, integration parameters, key performance indicators, optimization method, tools, and design robustness. Seven already‐designed TES systems are evaluated to assess the methodology's effectiveness, where the design procedures have been adapted to the proposed steps. Case studies involve various applications with both sensible and latent TES systems, demonstrating the applicability of the proposed design procedure. A significant diversity exists among the design cases regarding the design objective, input, design, and output parameters. Nevertheless, the design procedure in each case can be deconstructed into the outlined design steps. The last design step has been excluded from all case studies due to insufficient information regarding the robustness of the design process. The paper demonstrates how a methodical approach can be applied to examine the TES design and the integration. The design steps proposed in this study can serve as a foundation for developing a more systematic approach for designing TES systems in future works, resulting in simplifying the design process.
