Book Description Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Chlorofluorocarbons (CFCs) and hydro chlorofluorocarbons (HCFCs) had been in commanding position, as ideal refrigerants, until their effect on the ozone depletion layer was discovered in year1974. The process of ozone layer depletion in the stratospheric layer of atmosphere, involves the catalytic destruction of ozone by the atoms of halogens such as chlorine and bromine. A variety of pure and mixtures of HFC refrigerants such R134a, R404A (R125/R134a/R143a, 44%/4%/52%), R410A (R-32/R-125, 50%/50%) are being used as substitutes for the conventional CFC/HCFC refrigerants. These refrigerants have zero Ozone depleting potential (ODP) and similar thermodynamic and transport properties as that of conventional CFC/HCFC refrigerants. But,the major limitation of these refrigerants has been, that, these have lower value of heat transfer coefficients compared to CFCs. In order to augment their heat transfer characteristics, the micro finned horizontal tubes are replacing the earlier smooth horizontal tubes. The present work has focused on evaluating condensation characteristics of pure and mixtures of HFC based refrigerants in practical air-conditioning systems using micro-fin tubes. 240 pp. Englisch.
