Abstract (en)
[origin: EP0964156A2] The method involves supercooling (E5) the coolant or low-temp. medium before feeding it into the pump (P). The supercooling is performed by indirect heat exchange with at least one refrigerating machine. The supercooling can be performed by indirect heat exchange with at least one sub-flow (11') in the coolant circuit.
