Abstract
A method and apparatus for exchanging heat between a plurality of circuits carrying fluids at different temperatures ranging from T.sub.o to T.sub.N includes at least one adjustable heat-carrying circuit for balancing the overall thermodynamic equilibrium of the heat exchanges. Each stage of a plurality of stages operates over one of the temperature intervals T.sub.o to T.sub.1, T.sub.1 to T.sub.2, . . . , T.sub.N-1 to T.sub.N, and includes at least one cell filled with a transfer fluid as both a liquid and a vapor. The vapor is transferred between cells of adjacent stages by compressors and by turbines. The liquid is transferred between cells of adjacent stages by pumps and by conduits having calibrated orifices. The adjustable heat-carrying circuit may either supply or remove heat and may extend through either a single cell or a plurality of adjacent cells.
