<p>In a cooling apparatus comprising a device for (pre)cooling the liquid coolant by means of its limited expansion, the invention provides a method of reduced energy consumption by (also) utilising for cooling, at least temporarily, the (pre)cooled liquid coolant as a liquid heat carrier, by causing at least a partial amount of the coolant to flow, by maintaining its liquid state without evaporation, through at least one heat exchanger (10). The method is preferably performed in an apparatus wherein the device for (pre)cooling the liquid coolant comprises two identical liquid recipients (1, 2) the upper inner space sections of which are alternately connectable to a phase separator (3), that is also connected to a collector conduit (50) of a liquid collector (9). The liquid recipients (1, 2) are also alternately connectable to a common supply conduit (54) which is, via a changeover valve (22), connected to the collector conduit (50) of the liquid collector (9), and to a common discharge conduit (51) that leads to a (pre)cooled liquid outlet (LO) of the device. A vapour outlet of the phase separator (3) is connected to a displacement pump (4) and a vapour inlet (VI) of the device. The common discharge conduit (51) of the liquid recipients (1, 2) is also connected, via a coolant pump (5), a heat exchanger (10), and a controlled closing valve (27), to the changeover valve (22) so that in typical modes of operation, the positive circulation of the liquid coolant within the device is allowed for.</p> |
