Hydrocarbon Refrigerants: Lubricant Interactions and Impact on Compressor Performance & Reliability
Hydrocarbon refrigerants such as R290 and R600a are seeing broader adoption across HVACR systems. This session examines their unique interactions with lubricants and the resulting implications for viscosity behaviour, oil return, and compressor reliability.

Session description
Hydrocarbon refrigerants such as propane (R290) and isobutane (R600a) are increasingly adopted across HVACR applications due to their favourable thermodynamic properties and very low global warming potential. A defining characteristic of these refrigerants is their high solubility in lubricants, which fundamentally differentiates them from other fluid classes and introduces distinct lubrication challenges.
A defining characteristic of hydrocarbon refrigerants is their high solubility in many lubricant types. This behaviour has important implications for viscosity control, lubrication film formation, and oil circulation within the system. Increased dilution of the lubricant can reduce effective viscosity, particularly under high load or elevated tempera ...
