“…The amount of heat recovered will be between 10 and 15% of the total heat dissipated in the condenser (Reindl and Jekel, 2007;Kassai, 2019;González and Gordín, 2020). In addition to all these, it has been observed that phase change materials, which have been researched extensively in recent years, also create energy savings during their use in cold storage (Yilmaz et al, 2020;Ismail et al, 2022;Le et al, 2023).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

Environment-Friendly Refrigerants for Sustainable Refrigeration and Air Conditioning: A Review

View full text Add to dashboard Cite

Refrigeration and air conditioning systems play a vital role in our modern society, and refrigerants are integral components of these systems. Traditional refrigerants like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) have caused significant environmental concerns because of their role in ozone depletion and global warming. Consequently, interest has increased in developing and implementing environmentally benign refrigerants possessing minimal global warming potential (GWP) and no ozone depletion potential (ODP). This review explores the emerging field of environment-friendly refrigerants such as natural refrigerants (NH3, CO2, hydrocarbons), hydrofluoroolefins (HFOs), hydrofluorocarbons (HFCs) with ultra-low GWP, hydrofluoroethers (HFEs) and mixtures or blends of these refrigerants. The article also compares their thermophysical, thermodynamic, environmental and safety properties, and their suitability for different applications. The key recommendations encompass the promotion of natural refrigerants, including NH3, CO2, and hydrocarbons, exhibit minimal environmental effects. Additionally, the exploration of HFOs and HFCs with ultra-low GWP and their mixtures as potential substitutes is advised. Transitioning to environment-friendly refrigerants is essential for achieving sustainable refrigeration and air conditioning systems, mitigating climate change, and ensuring the long-term viability of cooling technologies while preserving the environment.

Over the past decades, increase in food shortages and food costs with the drought caused by population growth and climate change, it becomes more important to prevent food losses with the widespread use of cold storage. That’s why many countries provide incentives for the widespread use of cold stores. However, with cold storages becoming more widespread, keeping energy consumption under control becomes an important issue. Especially in most developing countries, the status and energy performance of installed cold stores are unknown. In this study, energy consumption data were examined by using data from cold stores from different countries. The relationships between some parameters (capacity, volume, etc.) affecting energy consumption were analyzed for 67 established cold stores. In order to measure the energy consumption data of the system under ideal operating conditions, experiments were carried out in the test room under laboratory conditions and comparisons were made according to the data obtained from the field. The data obtained showed that energy consumption in cold stores increased by up to 30%, depending on operating conditions. Therefore, it is very important that cold stores are inspected by the relevant institutions after they are established and during their operation.
