Definitions
- the invention relates to an arrangement for tempering a Fountain solution and / or selected rollers one Printing machine according to the preamble of claim 1.
- the invention thus relates generally to the field of Printing using the offset printing process.
- the arrangement stands out by combining one as a closed system trained cooling fluid circulation system with a Refrigeration device from without affecting the Function and lifetime of the compressor arrangement different cooling capacity can be set.
- the cooling fluid circulation system therefore does not need a buffer memory in the form a storage container for temporary storage of excessive Cooling fluid quantities, but can be used as a closed circulation system be trained.
- a compressor e.g. a Piston compressor, designated by a maximum Speed can be switched to a reduced speed can, so that the output of the compressor 10 switched accordingly between full load and part load operation can be.
- the output of the compressor 10 is a Condenser 2 in connection, in which the refrigerant from gaseous is converted into the liquid state.
- the liquid refrigerant at the outlet of the condenser 2 is in a refrigerant collector 5, which serves as a store, introduced.
- the output of the refrigerant collector 5 is connected to the inputs of a first and second heat exchange device 3, 4.
- the first heat exchange device 3 is part of a dampening solution circulation system indicated at U I , which can be an open system with a storage container (not shown) for storing a sufficient amount of dampening solution.
- the second heat exchange device 4 is part of a closed cooling fluid circulation system indicated at U II for supplying a roller cooling device (likewise not shown).
- the output of the collector 5 is on the one hand the entrance of the first heat exchange device 3 via a Shut-off valve 8 and an expansion valve 11 and the other with the input of the second heat exchange device 4 via a Shut-off valve 14 and an expansion valve 16 connected.
- the output of the first heat exchange device 3 protrudes an evaporative pressure control valve 9 and a non-return valve 23, which is a flow towards the Prevents the heat exchange device 3 and in the opposite direction allows with the entrance of the Compressor 10 in connection while the output of the second Heat exchange device 4 in more detail below Flow control valve 15 described with the input of Compressor 10 is connected.
- the shut-off valves 8 and 14, which can be solenoid valves, and the flow control valve 15 are actuated as a function of a control device 13 which, as an input variable, receives the signals from sensors 114, 207 for detecting the temperature of the circulating systems U I and U II flowing fluid on the inflow side of the heat exchange devices 3 and 4, respectively.
- the expansion valves 11 and 16 are controlled as a function of the temperature of the refrigerant at the outlet of the heat exchange devices 3 and 4, respectively.
- an evaporation pressure control valve 9 can be provided, which is a decrease in the evaporation pressure in the Heat exchange device 3 under a certain lower Limit prevented.
- a bypass arrangement is provided to part of the gaseous refrigerant at the outlet of the compressor 10 back to lead to its entry page.
- a pressure detection valve 6 in the return line has the task regardless of respective operating state of the compressor 10 (full or Part-load operation) to ensure that a sufficient Refrigerant throughput guaranteed by the compressor 10 is. In particular, at partial load operation without Refrigerant return is too low a refrigerant throughput present by the compressor 10 so that it no longer would be cooled sufficiently and it would damage the Compressor 10 could come.
- Pressure sensors 19a and 19b detect the pressure of the refrigerant on the inlet and outlet side of the compressor 10 to this at too low pressure on the inlet side or excessive pressure on the outlet side switch off to damage the compressor prevent how they can occur when certain lower and upper pressure limit values are exceeded or fallen below.
- an injection valve 7 to Injecting liquid refrigerant into the gaseous Output of the pressure detection valve 6 is provided so that the gaseous output of the pressure detection valve 6 to a preventing damage to the compressor 10 Temperature can be reduced.
- the injector 7 is connected to the output of the collector 5 and receives the Control signals for setting the coolant injection quantity of a temperature sensor at the inlet of the compressor 10.
- On Pressure switch 18 is on the input side of the compressor 10 provided to 6 before opening the pressure detection valve Switch compressor 10 from full to part load operation.
- Pressure switches 19c and 19d at the input of capacitor 2 supply control signals to a pair of fans of the condenser, around them individually according to the pressure of the gaseous Switch refrigerant on or off and at different ambient temperatures constant Maintain pressure conditions in the refrigerant circuit.
- the flow control valve 15 provided at the outlet of the second heat exchange device 4 for the cooling fluid circulation system U II , that is to say for the system with a higher cooling energy requirement than that of the dampening solution circulation system U I , enables the refrigerant throughput through the heat exchanger 4 to be steplessly regulated and thus adjusted the cooling energy supplied to the heat exchanger 4 is between 0% and a maximum value, for example 100%.
- the flow control valve 15 simultaneously takes over the function of a shut-off valve in the 0% position.
- the flow control valve 15 can be set via the control device 13 to an upper limit of the cooling energy supplied to the second heat exchange device 4 if further cooling energy is required to supply the first heat exchange device 3 of the dampening solution circulation system U I.
- the flow control valve 15 can be set to, for example, a limit value of 2/3 of the total cooling output emitted by the compressor 10 when the dampening solution circulation system U I is in operation, so that it is ensured that a third of the total power for supplying the first heat exchange device 3 is available regardless of the need for the cooling fluid circulation system U II .
- the shut-off valve 14 at the input of the second heat exchange device 4 for the cooling fluid circulation system U II is in the closed position, and the flow control valve 15 is also set to the position 0% refrigerant throughput, so that no refrigerant can flow through the heat exchange device 4 .
- the lower cooling capacity requirement of the first heat exchange device 3 of the fountain solution circulation system U I is taken into account in that the compressor 10 is switched to part-load operation (for example 50% of the maximum capacity) by reducing the speed of the compressor 10 accordingly.
- the pressure detection valve 6 in the return line opens therefore, so that part of the gaseous refrigerant on Flow the output of the compressor 10 back to its input can.
- the injector 7 is controlled to the temperature to a permissible for the compressor 10 To decrease value. If the cooling capacity is the first Heat exchange device 3 of e.g. 1/3 of the maximum Cooling capacity can e.g. 10% of the output from the compressor 10 Power diverted and to the inlet of the compressor to be led back.
- the shut-off valve 14 at the entrance of the second Heat exchange device 4 is open, and the flow control valve 15 will correspond to the Cooling fluid inlet temperature to the heat exchange device 4 set a refrigerant flow between 0% and 100%.
- the shut-off valve 8 at the entrance to the first Heat exchange device 3 is closed, so that Refrigerant only of the second heat exchange device 4 is fed.
- the compressor 10 can accordingly Refrigeration energy requirement of the second heat exchange device 4 below under these circumstances work at full load or part load, depending on the cooling capacity between 0% and 100% on the part of the flow control valve 15 is specified.
- heat exchange device 3 prevents that refrigerant from the exit of the second Heat exchange device 4 to the exit of the first Heat exchange device 3 can flow.
- the shut-off valves 14 and 8 at the inputs of Heat exchangers 3 and 4 are open, and that Flow control valve 15 at the outlet of the second
- the heat exchange device 4 is controlled by the control device 13 to a maximum cooling capacity corresponding to 2/3 of the Total cooling capacity of the refrigeration device set so that that of the second heat exchanger 4 supplyable cooling capacity to one area e.g. between 0% and is limited to approximately 66%.
- the rest of the total cooling capacity stands for the supply of the first Heat exchange device 3 regardless of the need of the second Heat exchange device 4 always available.
- the compressor 10 between Switched full and part load operation, whereby in Part-load operation, a refrigerant return similar to that Operating mode "Only dampening solution cooling" can take place.
- the Shut-off valve 14 switches when the cooling fluid set temperature is reached, which is detected by the sensor 207, the Refrigerant flow through the second heat exchange device 4 or enables such a refrigerant flow as soon as the predetermined cooling fluid temperature is exceeded, wherein according to the prevailing cooling capacity requirement of first heat exchanger 3 of the compressor 10 under partial or Full load works.
- the invention was previously based on an arrangement with a refrigeration device described that only one contains only power-switchable compressor. Instead of two or more of them could be parallel to each other arranged compressors are provided, each not need to be switchable, but according to that respective energy requirements can be switched on or off, so that at the common output the compressor has a maximum or minimal cooling capacity.
- the return of the gaseous refrigerant from the common exit to one common input of the compressor connected in parallel in an analogous manner to that described above Refrigeration device take place.
- Fig. 2 shows the second embodiment of the invention, the differ from the previous one and shown in FIG. 1 Embodiment differs in particular in that a Refrigerant recirculation using a Pressure detection valve 6 containing return line is omitted and the adjustment range of the flow control valve 15 between a maximum value of e.g. 100% and is limited to a minimum value that is much larger than 0%, e.g. 40%.
- the means that in the recycled refrigerant is a liquid refrigerant Can inject cooling.
- the embodiment according to FIG. 2 is therefore characterized by a smaller number of components out, reducing the effort for assembly and maintenance is reduced and cost-effective operation can be achieved can.
- FIG. 2 be designed as that of FIG. 1.
- two or more compressors 10 ', 10' 'are provided in parallel lie to each other and are designed so that they each a fraction, e.g. 50% of the total required Can deliver cooling capacity.
- Each compressor is 10 ', 10' '
- the outputs of the check valves 23 ', 23' ' are connected to the Input of capacitor 2 in connection.
- the entire of the Cooling device delivered cooling capacity between 20% and 100% continuously by means of the flow control valve 15 can be set.
- Overheating of the compressors 10 ' 10 '' in the "cooling fluid cooling" mode, i.e. at open shut-off valve 16, is limited by the Adjustment range of the flow control valve 15 to Prevents a minimum value that is significantly greater than 0%, so that there is always a certain amount of refrigerant in the direction will flow to the compressors 10 ', 10' '.
- the refrigeration device according to both of the above Embodiments of the invention are preferably one separate unit with integrated heat exchange devices 3, 4 and inlet and outlet connections for the ends to be connected Dampening solution or cooling fluid circulation systems.
- the invention thus enables the cooling power output by the compressor 10 to be specifically adapted to the respective operating conditions. This ensures an energy supply to the second heat exchange device 4, which is matched to the requirements of the cooling fluid circulation system U II in the different operating modes, so that an increased energy supply to the heat exchange device 4 is avoided.
- the cooling fluid circulation system U II can therefore be designed as a closed system, since an energy buffer store in the form of a cooling fluid storage container can be dispensed with.
