Hydrocarbons as Substitutes for Halogenated Refrigerants in Refrigerating Systems
The paper deals with the use of R-290/600a(50/50) and R-600a, that are now considered as alternative to R-134a to substitute R-12 in domestic refrigeration. A theoretical analysis of the mixture performance shows that both hydrocarbon refrigerants may be used. Tests of certain hermetic compressors confrrm that the mixture can be used both for old and new equipment, while the isobutane must be u...
متن کاملEnvironmental Impacts of Halogenated Refrigerants and Their Alternatives: Recent Developments
A certain percentage of the vapor compression based refrigeration, air conditioning and heat pump systems continue to run on halogenated refrigerants due to its excellent thermodynamic and thermo-physical properties along with the low cost. However, the halogenated refrigerants have adverse environmental impacts such as ozone layer depletion potential and global warming. Hence, it is necessary ...
متن کاملCarcinogenicity studies on halogenated hydrocarbons.
A series of halogenated compounds was tested by oral intubation in 200 Osborne-Mendel rats and 200 B6C3F1 mice of both sexes. Carbon tetrachloride, used as a positive control, induced liver and adrenal tumors in mice and neoplastic nodules in the livers of rats. 1,2-Dibromoethane and 1,2-dibromo-3-chloropropane caused stomach tumors with many metastases in both rats and mice. Chloroform, known ...
