Abstract
Official abstract text for this publication.
Embodiments are described herein to provide refrigerant and/or refrigerant composition that is suitable for providing lubrication to, for example, moving parts of a chiller system. Embodiments are also described herein to provide an additive, such as a corrosion inhibitor and/or stabilizers, that can be added to the refrigerant to form refrigerant compositions that is suitable for providing lubrication to, for example, moving parts of a chiller system.
First claim
Opening claim text (preview).
What is claimed is: 1. A refrigerant to provide lubrication in an HVAC system, comprising: 1-chloro-3,3,3 trifluoropropene (E); and wherein the refrigerant provides lubrication and is oil-free. 2. The refrigerant of claim 1 , wherein the benzotriazole is added to the refrigerant in a range of about 0.01% to about 1% by a weight of the refrigerant. 3. The refrigerant of claim 1 , wherein the benzotriazole is added to the refrigerant in a range of 0.001% to 0.5% by a weight of the refrigerant. 4. A refrigerant blend to provide lubrication in an HVAC system, comprising: 1-chloro-3,3,3 trifluoropropene (E); and benzotriazole, wherein the refrigerant blend provides lubrication and is oil-free. 5. The refrigerant blend of claim 4 , wherein the benzotriazole is added to the refrigerant in a range of about 0.01% to about 1% by a weight of the refrigerant. 6. The refrigerant blend of claim 4 , wherein the benzotriazole is added to the refrigerant in a range of 0.001% to 0.5% by a weight of the refrigerant.
