摘要:
The present invention relates to compositions that are useful for compatibilizing a conventional compression refrigeration lubricant and a hydrofluorocarbon and/or hydrochlorofluorocarbon refrigerant in a compression refrigeration or air conditioning system. Additionally, these compositions promote efficient return of lubricant from the non-compressor zones to the compressor zones of refrigeration and air conditioning systems.
摘要:
The present invention relates to compositions comprising fluorinated olefins or fluorinated ketones, and at least one alcohol, halocarbon, hydrofluorocarbon, or fluoroether and combinations thereof. In one embodiment, these compositions are azeotropic or azeotrope-like. In another emebodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.
