Fluorinated gases (F-gases) used as refrigerants in air conditioners have a significant global warming effect, so their release into the atmosphere must be minimized. The purpose of this study was to evaluate and compare environmental impact two treatment methods: reclamation destruction after refrigerant recovery. Plant data for R410A, R32, R134a, R22 were collected from Japan Europe evaluated...

The global concern regarding the environmental repercussions of refrigerants has escalated due to their adverse effects. These substances deplete ozone layer and intensify greenhouse effect. International agreements such as Montreal Kyoto Protocols COP21 have imposed restrictions on with high warming potential (GWP) address these issues. This study aims explore feasibility, energy efficiency, i...

A mixed-valent, one-dimensional Cu(I/II) coordination polymer with the formula [CuII{CuI3(Hmpba)(mpba)2}DMF] ⋅ ∼3DMF was obtained bifunctional ligand 4-(3,5-dimethyl-1H-pyrazol-4-yl)benzoic acid (H2mpba) in N,N-dimethylformamide (DMF) via solvothermal reaction. The compound exhibits a trinuclear {CuI3(Hmpba)(mpba)2}2− metallo-linker softer Cu(I) linearly-coordinated by pyrazolate nitrogen donor...

This research presents an energy efficiency improvement solution for supermarkets with the use of low-E glass doors open refrigerators and a digital semi-hermetic compressor to fix speed compressors. The impact door’s installation causes its load be reduced by 40%, shuts down frequently, which decreases lifetime. In order ensure that energy-saving solutions do not affect maintenance costs, is p...
