Cooling device for temperature-control of e.g. roller of printing machine, has capacitor whose input is connected with outputs of both compressors, where output of capacitor is connected with inputs of both vaporizers

摘要

The device has a temperature control circuit (FT) and a dampening agent circuit (FM) comprising vaporizers (11, 12) and compressors (13, 14) for temperature-control of two fluids, respectively. A capacitor (17) has an input connected with outputs of the compressors and an output connected with inputs of the vaporizers. Adjustable or controllable expansion valves (15, 16) are arranged between the output of the capacitor and inputs of the vaporizers. A pressure and/or temperature detecting unit detects pressures and/or temperatures at positions of the refrigerant circuit. An independent claim is also included for a method for temperature-control of different components of a printing machine and a machine tool.
