1 . A refrigerant comprising at least about 97% by weight of the following four compounds, with each compound being present in the following relative percentages: from 1% by weight to 2%+/−0.5% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)), from about 73% by weight to about 87% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)), 4.4%+/−0.5% by weight 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), and from about 6.6% by weight to about 20.6% by weight trifluoroiodomethane (CF 3 I). 2 . A heat transfer composition comprising a refrigerant of claim 1 . 3 . The heat transfer composition of claim 2 further comprising a lubricant. 4 . The heat transfer composition of claim 2 further comprising a stabilizer. 5 . The heat transfer composition of claim 3 further comprising a stabilizer. 6 . A refrigerant comprising at least about 97% by weight of the following three compounds, with each compound being present in the following relative percentages of: from 1% by weight to 3% by weight trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E), from about 77% by weight to about 83% by weight trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E), and from about 15% by weight to about 21% by weight trifluoroiodomethane (CF3I). 7 . A heat transfer composition comprising a refrigerant of claim 1 . 8 . The heat transfer composition of claim 2 further comprising a lubricant. 9 . The heat transfer composition of claim 2 further comprising a stabilizer. 10 . The heat transfer composition of claim 3 further comprising a stabilizer.
