METHOD AND USE OF A DEVICE FOR COOLING PROCESS WATER USED IN THE PRODUCTION OF FRESHLY MIXED CONCRETE

The method for cooling a liquid (2) in which a coolant comprising a refrigeration-liquefied gas is introduced into the liquid (2) and the corresponding device (1) make possible, in an advantageously simple manner, the production of cooled liquids (2), which, for example, can be used as process water...

Zusammenfassung:	The method for cooling a liquid (2) in which a coolant comprising a refrigeration-liquefied gas is introduced into the liquid (2) and the corresponding device (1) make possible, in an advantageously simple manner, the production of cooled liquids (2), which, for example, can be used as process water in the production of freshly mixed concrete. In this case the enthalpy content of the coolant, preferably of liquid nitrogen, is utilized in a good manner, by firstly using the vaporization enthalpy, and secondly the heating of the nitrogen after vaporization up to ice temperature, for cooling the liquid.
