  • Lubricant blends to reduce refrigerant solubility
    Patent number: 11085680
    Abstract: Compositions, methods, systems, and applications herein are directed to lubricant blends that balance solubility and viscosity of a refrigerant, where in some cases the lubricant blends herein help reduce solubility of a refrigerant. A lubricant blend includes a mixture of two or more different types of lubricants to reduce refrigerant solubility.
    Type: Grant

  • Rapid field testing method for detecting lubricant or refrigerant additives
    Patent number: 10739270
    Abstract: A method for operating a field testing device to detect an additive in a refrigerant and/or lubricant. The method includes mixing a reactive medium with the refrigerant and/or lubricant. The reactive medium is configured to react with any additive present in the lubricant and/or refrigerant to form a product that has a different color than the reactive medium. The method also includes determining the additive concentration of the lubricant and/or refrigerant by utilizing the color of the reaction mixture. The field operating device is portable such that the additive concentration may be determined while in the field.
