摘要:
The present invention relates to the field of compression refrigeration and air conditioning. Specifically, the present invention relates to a tracer-containing compositions comprising refrigeration/heating fluid and tracer compound(s). Additionally, the present invention relates to a method for detecting tracer compounds to identify gases after leaving the custody of the original manufacturer or prior source, and the verification of authenticity. The aforementioned method provides for the detection of tracer compounds, which in turn, may alert the refrigeration industry to when dilution, adulteration, contamination or other unauthorized practices have occurred with refrigeration products.
摘要:
The present invention relates to compositions comprising iodotrifluoromethane and an effective amount of at least one stabilizer selected from the group consisting of hindered phenols, thiophosphates, butylated triphenylphosphorothionates, organo phosphates, phosphites, aryl alkyl ethers, terpenes, terpenoids, epoxides, fluorinated epoxides, oxetanes, ascorbic acid, thiols, lactones, thioethers, amines, nitromethane, alkylsilanes, benzophenone derivatives, aryl sulfides, divinyl terephalic acid, diphenyl terephalic acid, ionic liquids, and mixtures thereof. These stabilized iodotrifluoromethane compositions may be useful as working fluids in multiple applications including cooling apparatus, such as refrigeration, air-conditioning, chillers, and heat pumps.
摘要:
Disclosed herein are refrigerant and heat transfer fluid compositions comprising 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone and at least one hydrofluorocarbon for use in refrigeration and air conditioning systems employing a centrifugal compressor. The compositions may be azeotropic or near-azeotropic.
