1. A method for providing a system for cooling air in an automobile comprising:
- (a) providing in the automobile a vapor compression air conditioning system having at least one compressor and at least one condenser; and
(b) providing a heat transfer composition in said system, said heat transfer composition consisting essentially of;
(i) at least about 70% by weight of a refrigerant;
(1) having no substantial acute toxicity as measured by inhalation exposure to mice and rats;
(2) having a global warming potential of not greater than 150; and
(3) comprising a fluoroalkene consisting essentially of 1, 3, 3, 3-tetrafluoropropene (HFO-1234ze), wherein said HFO-1234ze comprises at least about 97% by weight of transHFO-1234ze; and
(ii) lubricant consisting essentially of polyalkylene glycol(s) and/or polyol ester(s).
