Abstract

The invention pertains to heat transfer compositions, particularly to automobile refrigerants comprising a hydrofluoroalkene, an iodocarbon, and at least one lubricant having hydrogen atoms and carbon atoms, wherein no more than 17% of the total number of hydrogen atoms which are attached to a carbon atom are tertiary hydrogen atoms.

Claims

exact text as granted — not AI-modified
1 . A heat transfer composition comprising: (a) a refrigerant comprising: (i) at least a first compound selected from at least one of 2,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and HFC-32; and (ii) at least about 40% by weight of CF 3 I; (b) lubricant; and (c) a stabilizer. 
     
     
         2 . The composition of  claim 1  wherein said at least a first compound comprises 2,3,3,3-tetrafluoropropene. 
     
     
         3 . The composition of  claim 1  wherein said at least a first compound comprises trans-1,3,3,3-tetrafluoropropene. 
     
     
         4 . A mobile air conditioning system comprising the heat transfer composition of  claim 1 . 
     
     
         5 . A heat transfer system comprising the heat transfer composition of  claim 1 . 
     
     
         6 . A method of transferring heat to or from a fluid or body comprising contacting the fluid or body with the heat transfer composition of  claim 1 . 
     
     
         7 . A heat transfer composition comprising: (a) a refrigerant comprising: (i) at least a first compound selected from at least one of 2,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and HFC-32; and (ii) at least about 25% by weight of CF 3 I; (b) lubricant; and (c) a stabilizer. 
     
     
         8 . The composition of  claim 7  wherein said at least a first compound comprises 2,3,3,3-tetrafluoropropene. 
     
     
         9 . The composition of  claim 7  wherein said at least a first compound comprises trans-1,3,3,3-tetrafluoropropene. 
     
     
         10 . A mobile air conditioning system comprising the heat transfer composition of  claim 7 . 
     
     
         11 . A heat transfer system comprising the heat transfer composition of claim  34 . 
     
     
         12 . A method of transferring heat to or from a fluid or body comprising contacting the fluid or body with the heat transfer composition of  claim 7 . 
     
     
         13 . A heat transfer composition comprising: (a) a refrigerant comprising: (i) at least a first compound selected from at least one of 2,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and HFC-32; and (ii) at least about 50% by weight of CF 3 I; (b) lubricant; and (c) a stabilizer. 
     
     
         14 . The composition of  claim 13  wherein said at least a first compound comprises 2,3,3,3-tetrafluoropropene. 
     
     
         15 . The composition of  claim 13  wherein said at least a first compound comprises trans-1,3,3,3-tetrafluoropropene. 
     
     
         16 . A mobile air conditioning system comprising the heat transfer composition of  claim 13 . 
     
     
         17 . A heat transfer system comprising the heat transfer composition of  claim 13 . 
     
     
         18 . A method of transferring heat to or from a fluid or body comprising contacting the fluid or body with the heat transfer composition of  claim 13 .
