  • LUBRICANT DEFOAMING ADDITIVES AND COMPOSITIONS
    Publication number: 20160032209
    Abstract: Defoaming compounds that can be included in a HVAC system are provided. In some embodiments, the refrigerant compositions and/or additives may include one or more defoaming compounds that have one or more of the following properties: helping reduce a surface tension of the lubricant and/or refrigerant; having a different surface tension than the lubricant and/or refrigerant; being substantially non-dissolvable with the refrigerant and/or lubricant; and/or having less dense than the refrigerant and/or lubricant so that the compounds may stay on the surface of the refrigerant and/or lubricant.
