“…This scaling-down process emphasises the significance of improving subcomponent design to achieve optimal outcomes. Similar to other large electric packages, the successful miniaturisation of PES units relies on the enhancement of subcomponent design to ensure efficient and reliable operation and performance [20][21][22][23][24][25][26][27][28][29]. The compact arrangement of electronic subcomponents leads to a higher concentration of power-loss density in the form of heat, resulting in increased internal temperatures within the package.…”

Achieving the global electricity demand and meeting the United Nations sustainable development target on reliable and sustainable energy supply by 2050 are crucial. Portable energy storage (PES) units, powered by solid-state battery cells, can offer a sustainable and cost-effective solution for regions with limited power-grid access. However, operating in high-dust and high-temperature environments presents challenges that require effective thermal management solutions. This paper is a comprehensive review of thermal management systems for PES units, with a specific focus on addressing the challenge of overheating in airtight designs. The review of various active and passive cooling systems is conducted through extensive study of the relevant literature, which is significant in providing insights into the operation, performance parameters, and design options for different cooling system technologies. The findings from this review show heat pipe (HP) technologies as key cooling-system solutions for airtight PES units. Specifically, loop and oscillating HPs, as well as the vapour chamber, offer desirable features such as compactness, low cost, and high thermal conductivity that make them superior to other alternatives for the cooling systems in PES. The insights and knowledge generated via this review will help facilitate the design and development of innovative, efficient, and reliable PES units, thereby contributing to the advancement of off-grid renewable energy applications and enabling sustainable power solutions worldwide. Furthermore, an appropriate design of PES units can help in reducing capital and maintenance costs.

“…Available literature sources [66][67][68][69] discuss various technical and organizational issues related to the very process of FAS operation. The problem associated with minimizing the probability of a false alarm through the use of appropriate detectors, e.g., a linear smoke detector, should be taken into account at the engineering stage and during the operation process itself [1,15,25].…”

Assessing the Operation System of Fire Alarm Systems for Detection Line and Circuit Devices with Various Damage Intensities

et al. 2022

The paper presents a method for assessing operation processes for Fire Alarm Systems (FAS) applied in civil structures, based on use analysis. Individual FAS devices include components with varying ‘lifetimes’ and damage intensities λ. This is because these elements are operated in different internal and external environments. Probability distributions with various damage λ and recovery µ intensity values must, hence, be taken into account for the FAS operation process and to determine the R(t) reliability. The life cycle of elements comprising a FAS can be divided into three distinguishing time periods. The first is the so-called ‘childhood’. The second, the longest, is characterized by damage intensity λ = const, and the third period is where FAS is unfit more frequently. Based on knowledge of actual FAS operation process data, it is possible to determine damage λ and recovery µ intensity parameters. Such data can be employed to determine FAS reliability parameters within the presented service life intervals. The authors of the article first discuss the basic issues associated with FAS, followed by analyzing the current status of the topic. They also present power supply matters and system solution examples, develop an operation process model and determine selected operational indicators for the structures in question. The paper ends with conclusions.

“…Due to the particular tasks performed in facilities, FAS must be characterized by a high hardware reliability [6,21,31,37], and also as a decision on the state of security within the monitored area that is worked out based on the data received from detectors [5,11,33,34]. In the context of the tasks described by the authors of the article, especially the second of the aforementioned aspects may be considered as a diagnostic and measurement issue, taken into account during FAS operation.…”

“…All FACUs monitoring a given structure or such a vast area in terms of fire safety are connected through a double transmission cable, a so-called ring, for reliability purposes or operate in a so-called star system, where a master FACU is located in its central place [19,20]. In the case of these systems, the distance of remote locations supervised by a given FACU can exceed the permissible length of lines, detection circuits or control lines [21,22]. Due to the costs of executing a given fire system (e.g., execution of several detection lines to a remote protected part or facility) over a vast area, such a solution may be cheaper or more reliable than, e.g., the application of a focused FAS [23,24].…”

The article presents issues regarding the impact of operating conditions on the functional reliability of representative fire alarm systems (FASs) in selected critical infrastructure buildings (CIB). FAS should operate correctly under variable environmental conditions. FASs ensure the safety of people and CIB. Operational measurements for 10 representative systems were conducted in order to determine the impact of environmental conditions on FAS reliability. Selected operational indices were also determined. The next stage involved developing two models of representative FASs and the availability, pre-ageing time and operating process security indices. Determining operational indices is a rational selection of FAS technical and organizational solutions that enables the reliability level to be increased. Identifying the course of the FAS operating process security hazard changes in individual system lines, particularly at the initial operation stage, enables people that supervise the operation to affect operating parameters on an ongoing basis. The article is structured in the following order: issue analysis, FAS power supply in CIB, operational test results, selected FAS operating process models, determination of operational and security indices, and conclusions.
