Abstract
A lubricant additive for introduction into an AC/R system to improve lubricant miscibility and performance in the AC/R system.
Claims29
A device comprising:
- a container including a first port, wherein the container stores a first composition consisting essentially of a miscibility agent and a hydrolytic agent, wherein the miscibility agent includes a polyolester, wherein the first port is configured to connect to a second port of an air conditioning system or a refrigeration system containing a second composition including (a) a lubricant having a miscibility with respect to a refrigerant and (b) the refrigerant, such that the first composition is input into the air conditioning system or the refrigeration system and then mixed with the second composition therein such that the miscibility of the lubricant with respect to the refrigerant is increased.
A method comprising:
- causing an addition of a composition to a mixture of a hydrofluorocarbon (HFC) refrigerant and at least one of a mineral oil lubricant or an alkyl benzene lubricant, wherein the at least one of the mineral oil lubricant or the alkyl benzene lubricant has a miscibility with respect to the HFC refrigerant, wherein the composition consists essentially of a miscibility agent and a hydrolytic agent, wherein the miscibility agent includes a polyolester, wherein the addition includes connecting a first port of a container storing the composition to a second port of a climate control system containing the HFC refrigerant and the at least one of the mineral oil lubricant or the alkyl benzene lubricant such that the composition is mixed with the HFC refrigerant and the at least one of the mineral oil lubricant or the alkyl benzene lubricant therein such that the miscibility of the at least one of the mineral oil lubricant or the alkyl benzene lubricant with respect to the HFC refrigerant is increased;
- and
- causing the climate control system to operate based on the addition.
