FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of replacing existing liquid heat carrier contained in a heat-transfer system, having evaporation temperature from 35.5F to 50F and condenser temperature from 80F to 120F, involving removal of at least a portion of the existing liquid heat carrier from the system, wherein the existing liquid heat carrier is selected from a group consisting of HFC, HCFC, CFC and combination thereof; and feeding the replacing heat carrier composition into the system, containing 1,1,1-trifluoro-3-chloropropene (HFCO-1233zd). The invention also relates to a heat-transfer method using a liquid heat carrier containing trans-1,1,1-trifluoro-3-chloropropene. ^ EFFECT: said heat carrier has higher efficiency. ^ 69 cl, 8 tbl, 6 ex |
