1. A method of operating a node (1) heat exchanger (2) for transcritical and a subcritical state by the initial location of the at least two heat exchangers (2) parallel to the subcritical state, characterized in that a at least one heat exchanger (2) under transcritical state sequentially with other heat exchangers and a input terminal (a) and output (B) at opposite ends of the assembly (1), and switch the heat exchangers (2) between the parallel arrangement and the arrangement sequence by m closing the first conduit (4) connecting said input (A) with the first channel (5) of each heat exchanger (2), after the first heat exchanger (2) and between every second heat exchanger (2) and a second conduit (6) connecting said yield (V) with the second channel (7) of each heat exchanger (2), between other teploobmennikami.2. A method according to claim 1, wherein said heat exchanger provides (2) a double-loop heat transfer between two substantially liquid media, such as refrigerant and the brine, characterized in that each circuit is switched between the parallel arrangement and the arrangement posledovatelno.3. A method according to any one of claims 1 or 2, characterized in that a whole heat exchangers (2) successively under transcritical sostoyanii.4. Node (1) heat exchanger (2) having an inlet (A) and output (B) at opposite ends of the assembly (1), a first conduit (4) connected to said input (A) and the first channel (5) of each heat exchanger (2 ) and a second conduit (6) connected to said output (B) and a second channel (7) of each heat exchanger (2), characterized in that the valve (3)
