Definitions

  • the invention relates to a tempering device for printing machines, with a Compression refrigeration system with a condenser and an evaporator, in the a refrigerant circulates, a free cooling circuit, in which a coolant, in particular Water circulates, a process water circuit in which a coolant for pressure rollers or a dampening solution for the offset pressure circulates, and heat exchange means for cooling the process water circuit using the compression refrigeration system and / or the Freikühlernikes.
  • Temperature control systems for printing presses are in various embodiments known. These are usually cooling systems, since during operation of a Printing machine inevitably some warming occurs, which is the Can affect print quality.
  • the cooling can be done by water cooling the friction rollers using a continuous line system or - in offset printing - by a cooled dampening solution applied to the rollers is applied. Occasionally, even cooled air is applied to certain parts or Inflated assemblies of printing machines.
  • Indirectly cooled systems are usually water cooled.
  • the process water is in an integrated water / water heat exchanger cooled by the cooling water of an external source.
  • Process water also by mixing with the cooling water of the external source cooled. Since a separation of the circuits is inevitably not possible, is suitable This procedure is not for the cooling of dampening solution.
  • Directly cooled systems with a water-cooled condenser in the refrigeration circuit usually obtain their cooling water from central cooling water systems. This are often systems with free coolers or evaporative coolers.
  • the temperature level the cooling water of these external cooling systems is always low enough to ensure adequate cooling of the water-cooled condenser To ensure refrigeration system. Also, the temperature level is in most Cases sufficient to other peripherals on printing machines like Air supply cabinets or drying cabinets sufficient with cooling too supply. But the temperature level of this cooling water is not always low is enough to direct this by means of a water / water heat exchanger Cooling of the process water for cooling the distributor rollers in the printing machine to use, appropriate systems are currently not used.
  • the conventional systems have the particular disadvantage that they have a require high energy input and have correspondingly high operating costs.
  • the invention is therefore based on the object, a cooling device for To create printing machines that manage with significantly lower energy consumption and an effective temperature control of different tempering media permit, without causing a mixing of the cooling water and the Temperierwasserströme comes.
  • a temperature control device of the above is characterized in that that a three-media heat exchanger is provided, in which the Process water circuit with both the compression circuit and with the heat exchanger is brought into heat exchange the free cooler cycle.
  • a three-media heat exchanger is understood to mean a heat exchanger be in separate chambers of the compression refrigeration cycle and the free cooling circuit is flowed through, while the process water or Temperiermedienniklauf both chambers in a separate line system passes.
  • the two chambers of the three-media heat exchanger a spatial unit, so for example a common housing with Form partition or constitute separate units.
  • the circle called the free-cooling circuit may be a water cooler have, which is traversed by a fan of outside air. It But it can also be another source of relatively cool water act.
  • the free cooling circuit can parallel to the three-media heat exchanger the Go through the condenser heat exchanger of the compression refrigeration system and for condensing the circulating in the compression refrigeration cycle refrigerant be used.
  • the flowed through by the compression refrigeration cycle chamber of the three-media heat exchanger preferably forms the evaporator of the compression refrigeration cycle.
  • the process water first passes through that of the two chambers of the three-media heat exchanger, that of the cooling water of the free cooling circuit is flowed through, so that the mentioned effect of pre-cooling used if the temperature conditions are suitable.
  • a particular advantage of the solution according to the invention is that the process water not only with the compression refrigeration cycle, but also with the free cooling cycle through heat exchangers in heat exchange stands that So not about the free cooler cycle directly as a process water cycle is used.
  • the process water cycle be formed by a dampening solution for the offset pressure, while the free cooling circuit Water, for example, contains water with antifreeze.
  • Each circuit may have piping systems made of materials suitable for the transported medium are particularly suitable, for example rustproof Steel in the case of corrosive media.
  • the single figure shows a possible embodiment of the invention.
  • a three-media heat exchanger is designated 10.
  • This Three-media heat exchanger 10 has a first chamber 12 and a second one Chamber 14, which in the illustrated embodiment to a spatial Unit summarized within a common housing and only are separated by a partition wall 16.
  • the two chambers can also form separate units.
  • In the first chamber 12 enters an inlet line 18 of a process water circuit, and from the chamber 12 occurs on the other an outlet line 20 of this process water circuit.
  • the two lines 18,20 are connected inside the two chambers with raw coils 22, in which the process water flows through the two chambers 12,14.
  • the inlet conduit 18 and the outlet conduit 20 are outside the three-media heat exchanger connected to a printing machine, not shown.
  • a water-air cooler 28 with a blower 30 With the first, left in the drawing lying chamber 12 of the three-media heat exchanger 10 are inlet 24 and outlet 26 of a free cooling circuit connected as a cooling source, a water-air cooler 28 with a blower 30 has.
  • the water-air cooler 28 is traversed by a coil 32, mounted on the tubes spaced, parallel metal plates 34 are increased by the heat transfer surfaces of the tubes.
  • the pipe coil goes outside the water-air cooler 28 in a flow line 36 of a free cooling circuit, the return line 38 on the other enters the water-air cooler 28 and connected to the coil 32 is.
  • the flow line 36 further includes a three-way valve 40, in the at the same time a coming from the return line 38 bypass line 42 occurs.
  • a three-way valve 40 which has a servomotor 44 and not in manner shown using an electronic control function of the Flow temperature of the cooling water can be controlled, part of the Cooling water fed directly from the return line 38 into the flow line when, for example, the cooled in the water-air cooler 28 Cooling water is too cold for the need.
  • a pump 46 Downstream of the three-way valve 40 is a pump 46, and subsequently to this a three-way valve 48 with actuator 50th
  • the three-way valve 48 is controllable, depending on the desired mode the cooling water is directed to one side or the other or distributed proportionately becomes. If the temperature in the free cooling circuit is sufficiently low, the Process water circuit in the left chamber 12 of the three-media heat exchanger 10 are cooled alone.
  • This compression refrigeration cycle 54 includes a compressor 56 already mentioned condenser heat exchanger 50, an expansion valve 58 and a Evaporator, which is formed by the second chamber 14 of the three-media heat exchanger.
  • the four elements mentioned are in a closed circle connected together, as is common in refrigerators.
  • a temperature sensor 62 determines the temperature in the line between the evaporator 14th and the compressor 56 and outputs signals indicative of the control of the expansion valve 58 are used.
  • the mode of action of the temperature control device according to the invention is intended subsequently to be discribed.
  • a water-air cooler of the illustrated Type it will depend primarily on the outside temperature, whether the Cooling of the press alone with the help of the cooling water of the free cooling circuit can be achieved or the Kompressionskarlte Vietnamese be switched on got to. If the outside temperature is sufficiently low, then only the cooling water circuit be used for the cooling by the three-way valve 48 to left side is opened and the cooling water in a closed circle the left chamber 12 of the three-media heat exchanger 10 flows through. Is the temperature while too low, so can already heated over the three-way valve 40 Cooling water from the return line 38 are mixed in the flow line.
  • the free cooler circuit may be the free cooler circuit for pre-cooling of the process water.
  • the process water first passes through the left chamber 12 in the drawing, in which a heat exchange with the cooling water of the free cooling circuit takes place, and then the chamber 14, passing through the evaporator the compression refrigeration cycle is formed.
