“…The amounts of HFC-152a and HFC-134a consumed are 2,240 tons and 1,108 tons, respectively, which together account for the largest portion of total gas consumption of 5,350 tons. This is because HFC-152a and HFC-134a are used to manufacture foam blowing, and fire suppression and explosion has increased due to the growth of the foam blowing, fire suppression and explosion industry [37][38][39].…”

Since fluorine compounds have both high ozone depletion potential and high global warming potential, the study of hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs) is crucial for climate change research. In this study, greenhouse gas (GHG) emissions from ozone-depleting industries in the Republic of Korea were estimated based on survey data on the use of fluorine compounds. This study is a response to the growing global attention to halocarbons that arose from the Kigali Amendment to the Montreal Protocol. Survey data on the consumption of fluorine compounds by application area were used to estimate emissions by applying the 2019 refinement IPCC Guidelines Tier 1a method. In addition, both the consumption ratio of fluorine compounds in the refrigeration and air conditioning application area and total fluorine compounds consumption by application area were compared with the values suggested by the UN Environment Programme to compare the current status with that in developing and developed countries. By comparing the derived GHG emissions with current emissions in the National Inventory Report, it was confirmed that 14,565 GgCO2eq of GHG emissions differed. In addition, through the replacement of fluorine compounds used as refrigerants, 14,422 GgCO2eq of the GHG emissions can be reduced.

“…4,5 Traditional polyurethane foaming agents are mainly chlorofluorocarbons (CFCs) [6][7][8] including the first generation of freon, 9 the second generation of 1,1-dichloro-1-fluoroethane (HCFC-141b), 10 and the third generation of perfluoropropane 11 and pentafluorobutane 12 with high ozone depletion potential (ODP) or high global warming potential (GWP). 13,14 However, traditional polyurethane foaming agents have apparent negative environmental effects, for example, freon and C 2 H 3 Cl 2 F are highly damaging to the ozone layer, while perfluoropropane and pentafluorobutane are typical greenhouse gases. 15,16 The Montreal Protocol and the Paris Agreement state that CFCs should be banned worldwide by 2030, and potent greenhouse gas hydrofluorocarbons are being phased out on a national scale.…”

Polyurethane foams are well‐known optimal thermal‐insulating materials, which have good thermal insulation performance, high strength, and lightweight properties. Here, we describe a chlorine‐free and fluorine‐free polyurethane chemical foaming agent (CFA‐1) that can react with isocyanate to release CO2 gas and foam polyurethane. We systematically studied its application performance in the field of polyurethane spraying by substituting the current most advanced and environment‐friendly physical foaming agent 1‐chloro‐3,3,3‐trifluoroprop‐1‐ene in different proportions. The results show that highly competitive mechanical properties lead to economical, environment‐friendly, and efficient features. The lower thermal conductivity, more compact and smaller bubble structure, and excellent compression strength were achieved by tuning the proportion of CFA‐1 from 20% to 60%. Thus, a promising material system was established for the development of the rigid polyurethane foam industry.

“…This need for energy touches all the sectors [5]. Among the most crucial ones there are the heating, cooling, and air conditioning fields, to which more than 20% of the total all-over the world energy consumption is attributed [6,7]. A drastic "change of course" is necessary, starting from mutating the concepts of energy sources and the way we conceive cooling and air conditioning.…”

One of the most significant contributions in energy request lies in refrigeration and air conditions. A drastic "change of course" is necessary, starting from mutating the concepts of energy sources and the way we conceive airconditioning. Therefore, the need for the scientific community to focus on renewable sources is growing, among them a very promising technique is solar cooling. In this paper a dynamic investigation of a solar absorption plant for airconditioning of an office building located in Naples (Italy) is introduced. The system is based on evacuatedtube solar collectors. The hot water coming from the solar collectors is employed to supply the cooling absorption system for cold-water producing used in the air conditioning. If the water coming from solar collectors does not have a temperature adequate to correctly supply the absorption system, the intervention of boilers as backup systems is planned. The investigation aims to analyse the energy performances of the system during the whole cooling season. To this hope a transient dimensional model was developed to dynamically simulate the solar cooling system coupled to the building.
