Abstract: A method for providing a refrigerant medium having a controlled flow temperature in a secondary cycle (20), wherein the refrigerant medium in the secondary cycle (20) takes up heat from one or more process coolers (22) and then gives off heat to primary water in a primary cycle (10) before it flows back to the process coolers (22), wherein at least two primary heat exchangers (12, 14) are present for cooling the refrigerant medium, in addition a bypass line (26) in the secondary cycle (20) branches off after exit from the process coolers (22) for bypassing the primary heat exchangers (12, 14), and the temperature in the secondary cycle (20) in the flow to the process coolers (22) is controlled via the setting of the bypass stream.

Abstract: A distributor device is provided for distributing liquid to tubes of a vertical tube-bundle apparatus that open out into an upper tube sheet. The distributor device includes a plurality of outlet openings that are directed downward. For improved liquid guidance, construction, and operation of the tube-bundle apparatus, the distributor device additionally includes laterally directed outlet openings. The tube-bundle apparatus includes a shell and a hood closing the shell at the top and a tube bundle arranged within the shell. The tube-bundle includes tubes opening out into an upper tube sheet and a distributor device arranged above the upper tube sheet, within the hood, for distributing liquid to the tubes.
