Âœ... Propane, Or R290, Is A Hydrocarbon Used As A Refrigerant In Domestic©Refrigerators Or In ±Small Commercial Refrigeration Appliances And Vending Machines. Thanks To Its Low Environmental Impact And Excellent Thermodynamic Properties, The Use Of R290 Is Increasing. Âœ... Propane Used In Refrigeration Applications Is Not Odorized Like Those For Domestic©Use (Domestic©Hydrocarbon Is Odorized So That It Is Quickly Detectable In The Event Of A Leak), Not Being Easily Detectable In Case Of Leaks. Âœ... Propane, Like All Other Hydrocarbon Refrigerants, Generally Has Very Good Miscibility With Any Type Of Lubricant. Due To The Good Solubility That Exists Between Mineral Oils And These Refrigerants, There Are Systems Where It May Be Necessary To Use Higher Viscosity Oils To Compensate For This Excess Solubility. Âœ... It Is Very Important When Working With Hydrocarbon Refrigerants That They Are Of High Purity, Since Any Proportion With Other Impurities, Such As Sulfides, Water, Etc., Can Contribute To The Degradation Of The Lubricating Oils Of The Installation, Breakage Of Compressors, Etc.
