Description:
The paper discusses the flame suppression and lubricant interaction of hydrocarbon (HC) mixtures for household refrigerator/freezers (R/Fs). he work focuses on blending the minimum amount of a fluoroiodocarbon (FIC) with previously optimized R/F-tested HC mixtures to reduce their flammability. ptimized HC mixtures were shown to be more energy efficient than CFC-12 operating in a conventional household R/F. fter the flame suppression of the mixtures was established, the HC mixtures, along with the selected quantity of the FIC, were retested in the same R/F in which the HC mixtures were previously optimized. he mixtures were removed from the R/F and tested in a gas chromatograph (GC) to determine whether they have the same affinity to the lubricant as established in non-FIC tests; the affinity of HCs to the lubricant was established before adding the FIC (oil affinity work is also included in the paper). urther GC testing determined the FIC's affinity to the lubricant by observing the composition shift of the HCs and the FIC. Cs are stratospheric-ozone friendly and have good heat transfer properties. heir ozone depletion and global warming potentials are substantially lower than those of CFC-12 and HFC-134a (the leading replacement for CFC-12). xperimental studies have revealed that specific HC mixtures are more energy efficient than CFC-12.
