Patent ID: 8272324

Claim:
A system for regulating the temperature of components of a printing press comprising: a cooling arrangement having a first supply circuit with a first outlet and being usable to provide a temperature-regulating fluid, at a first desired temperature level, in said first supply circuit for said temperature-regulating fluid, to a first one of said components that are to be temperature-regulated; a first cooling process with a first closed fluid circuit in said cooling arrangement, and which first cooling process is usable for cooling a first temperature-regulating medium which is circulating in said first closed fluid circuit to a first temperature level that is below one of the ambient and outside temperature; a first heat exchanger in said first closed fluid circuit; a second cooling process in said cooling arrangement, said second cooling process having a second closed fluid circuit, different from said first closed fluid circuit, which second cooling process is usable for cooling a second temperature-regulating medium, which is circulating in said second closed fluid circuit, to a second temperature level, which second temperature level of said second temperature-regulating medium is different from said first temperature level of said first temperature-regulating medium in said first fluid circuit, by the use of outside air; a second heat exchanger in said second closed fluid circuit; means thermally coupling said first supply circuit to each of said first cooling process, through said first heat exchanger in said first cooling process, and to said second cooling process through said second heat exchanger in said second cooling process; and means to provide, in response to said desired temperature level in said first supply circuit, a mixture of a first flow of a first portion of said temperature-regulating fluid which is cooled by sequential passage through said second heat exchanger of said second cooling process and also through said first heat exchanger of said first cooling process and which has exited said first heat exchanger, and of a second flow of a second portion of said temperature-regulating fluid which has passed through only said second heat exchanger of said second cooling process and which has exited said second heat exchanger, said mixture of said first portion and said second portions being formed after, in a fluid flow direction, said second heat exchanger, and to feed said resulting mixture as said temperature-regulating fluid into said first supply circuit.
