“…However, it is important to emphasize that the observed improvements and drops in the different models are negligible, given that the contribution of the end-of-life phase to the overall impact load of refrigerators was less than 1 %. Similar findings have been reported in other studies [ 13 , 44 ], confirming the minimal impact of refrigerant usage compared to other phases in the lifecycle of refrigerators, especially the use phase.…”

“…Therefore, in such cases, LCA will show the overall emission connected with increased/decreased HMs contamination and application of sewage sludge, while RA will refer to the HMs concentration and its toxic exposure. The similarities between both tools have been discussed by many researchers (Xue et al 2019;Linkov et al 2017;Pant et al 2004;Breedveld 2013). Breedveld (2013) showed the possibility to combine both tools which can provide widespread results and contribute to more detailed results shown in Table 1.…”

The commonly used and developing engineering environmental technologies do not remain neutral for an ecosystem. The deepening climate changes are generally considered as the effects of human activities. There is thus no doubt that any human interference in the environment should be comprehensively checked at the beginning for all its positive and negative aspects for the environment as well as society health. There are two different analytical tools useful in environmental management: life cycle assessment (LCA) and risk assessment (RA). The first follows the product from “from birth to the grave” summing the environmental impact at all stages of its “life” including such elements like producing, used electricity, transport and many others. LCA refers to quantification and classification of all effects at all life stages and provides direct and indirect possible environmental interactions. On the other hand, risk assessment focuses on linking stressors and its possibilities and severity. RA tools reveal environmental and human health impacts of strictly separated elements, providing insight as to which emission consists of an important threat. This paper is focused on summarizing two the most used methods and tools for supporting the decision making process in use of environmental engineering technologies. In this paper, the fundamental differences between LCA and RA and benefits from their use has been contained.

“…Serving as an international accord associated with the United Nations Framework Convention on Climate Change, its notable aspect lies in imposing mandatory emission reduction targets on 37 industrialised nations and the European community to curb greenhouse gas (GHG) emissions [8]. Fluorinated greenhouse gases (F-gases), primarily HFCs, are widely utilised as refrigerants in household refrigerators and commercial low-temperature process technologies in mobile air conditioning systems [17]. However, these F-gases significantly contribute to global warming, as recognised by the United Nations Framework Convention on Climate Change and the Kyoto Protocol [18].…”

Nowadays, the demand for obtaining high heat flux values in small volumes has increased with the development of technology. Condensing flow inside mini- and microchannels has been becoming a promising solution for refrigeration, HVAC, air-conditioning, heat pumps, heat pipes, and electronic cooling applications. In these applications, employing mini/microchannels in the condenser design results in the working fluid, generally refrigerant, undergoing a phase change inside the mini/microchannels. On the other hand, the reduction in the hydraulic diameter during condensation gives rise to different flow regimes and heat transfer mechanisms in the mini- and microchannels compared to the conventional channels. Therefore, the understanding of fluid flow and heat transfer characteristics during condensation of refrigerant inside mini- and microchannels has been gaining importance in terms of condenser design. This study presents a state-of-the-art review of condensation studies on refrigerants inside mini- and microchannels. The review includes experimental studies as well as correlation models, which are developed to predict condensation heat transfer coefficients and pressure drop. The refrigerant type, thermodynamical performance, and compatibility, as well as the environmental effects of refrigerant, play a decisive role in the design of refrigeration systems. Therefore, the environmental impacts of refrigerants and current regulations against them are also discussed in the present review.
