“…When the cell surface temperature reaches to the melting point of PCM it starts absorbing latent heat from the cell, maintaining its temperature close to its melting point. Conventionally, the use of PCM has been extensively researched for space cooling and thermal energy storage applications [67][68][69][70]. However, PCM-based cooling has recently received a lot of attention for battery cooling applications.…”

The thermal concerns, such as capacity loss, uneven temperature distribution and thermal runaway of the battery packs made of lithium-ion batteries (LIB) used in electric vehicles (EV), limits its applicability, especially in situations of high-power demand. This article analyses the causes of heat generation in lithium-ion battery packs, focusing on their dominance over total heat generation. It discusses the thermal issues arising from heat generation, their root causes, and influencing parameters. Further, it examines the effect of cooling systems on peak battery temperature and temperature uniformity, as well as their design, operating, and performance parameters. The review suggests that, when designing a cooling system, entropic heating should be considered alongside Joule heating during low discharge rates and high temperatures, which are the conditions that prevail when an EV cruises on highways in hot weather. Capacity fade of battery is caused by temperature-dependent factors such as the growth of the SEI layer, rise in separator resistance, and active material loss. Hence an effective battery cooling system should maintain a temperature range of 15°C to 35°C and ‘ΔTmax’ below 6°C. Out of the reviewed cooling systems, air cooling is found to be simple and cost effective, but inefficient for large battery packs. PCM based cooling technique offers greater temperature uniformity but is sensitive to melting point. Liquid cooling is most efficient but adds cost and complexity. Evaporative cooling can serve as a middle ground between air and liquid cooling with further research to put it into practice. The future research in battery thermal management may focus lowering the energy consumption of the cooling systems by taking into account, the precise cooling needs as per the modes of battery operation.

“…In hot and humid climates, air conditioning is the most paramount component of a hotel guestroom in providing ideal thermal comfort for the hotel occupants [10]. The main purpose of a cooling system is to maintain conditions that provide thermal comfort for the building occupants [11] and conditions required by the products and processes within the space [12].…”

The study examines the energy efficiency performance of hotel façades in relation based on the annual cooling energy consumption simulation. In achieving the objective, two case studies of high-rise city hotels are selected within the locality of Penang, Malaysia. The case studies are selected based on the year of construction coupled with the architectural styles encompassing conventional and modern design of hotel facades. In the traditional design of hotel facades, passive design elements including proper selection of window and wall materials alongside window-to-wall ratio (WWR) are less significant. Comparatively, elements of passive design in the modern hotel facades are notable. In assessing the thermal performance of the hotel façade, a case study of the conventional and modern high-rise city hotels in Penang are selected to undergo hourly cooling load simulation of hotel guestroom using the DesignBuilder program in establishing the hotel’s energy efficiency performance. The findings revealed, the average annual cooling energy of the conventional and modern high-rise city hotel guestroom is 553 kWh/m2 and 538 kWh/m2 respectively. The study concludes the elements of passive design including WWR, window material selection, and external wall colour are crucial in determining energy efficient hotel operations.

“…A building with a suitable climate design should be able to prevent heat flow between the external and internal surfaces. Thus, thermal comfort conditions can be provided by reducing the negative effects of temperature fluctuations on the residents [57][58][59][60][61][62][63][64][65][66][67]. Due to the ability of PCMs to adapt to temperature fluctuations and provide the balance in temperature without the need for any mechanical infrastructure, the temperature can be more stable, especially in the internal volumes of the buildings.…”

The need to reduce the use of fossil energy, which is running out and harmful to the environment, in response to the increasing energy demand with rapid urbanization, population growth and developing technologies reveals the necessity of research and application of technologies using renewable energy. Phase-change materials (PCM) are one of the most suitable methods for the efficient use of thermal energy originating from clean and sustainable energy sources. PCMs play important roles in a more energy-efficient world. The development of PCMs is one of the most challenging areas of study for more efficient thermal energy storage (TES) systems. This paper first explains the concept of PCMs and then describes the properties of these materials. After mentioned studies for improving the properties of PCMs, then PCM types and advantages-disadvantages are explained. Also, usage areas of PCMs in various sectors are also explained.
