A thermally powered heat transfer system which sequentially displaces thermal energy from the highest temperature heat source through two or more high temperature heat transfer loops to a heat sink. The system includes two or more two chamber compressors, with the high temperature chamber of each compressor being included in a high temperature heat transfer loop, there being a high temperature heat transfer loop for each compressor. The low temperature chamber of each compressor is included in one or more low temperature heat transfer loops. The source of heat for the evaporator heat exchanger of each high temperature heat transfer loop except one being heat from the condenser heat exchanger of another high temperature loop. The heat exchangers for the low temperature heat transfer loops being interchangeable depending on the mode of operation at any given time.
