摘要:
Provided are azeotrope-like compositions comprising pentafluoropropane, methanol, and dichloroethylene, and uses thereof, including use in aerosols, refrigerant compositions, refrigeration systems, and blowing agent compositions.
摘要:
The present invention provides compositions comprising pentafluoropropane, a second component selected from the group consisting of decafluoropropane, perfluorobutyl methyl ether and combinations of these, and a third component selected from the group consisting of methanol, 1,2-trans-dichloroethylene and combinations of these. The present invention further provides for refrigerants, blowing agents, foam compositions, polyol premixes, closed-cell foams, sprayable compositions, and the like, comprising the present compositions.

摘要:
A method and apparatus (10) for servicing refrigeration system (12) which provides a single device for recovering and reclaiming refrigerant, flushing the refrigerant system with solvent, and recharging the system with refrigerant. Refrigerant is recovered and reclaimed by withdrawing the refrigerant from the refrigeration system, vaporizing the refrigerant, removing the contamination from the refrigerant, liquefying the refrigerant, and then storing the cleaned refrigerant. The refrigeration system, or a component of it, can then be cleaned with solvent, using the same apparatus used to flush the refrigeration system with solvent. After flushing, the solvent is processed by vaporizing the solvent, removing the contamination from the solvent, liquefying the solvent, and then storing the cleaned solvent.
