Definitions

  • the invention relates to a cooling arrangement according to the preamble of patent claim 1.
  • Modern office workplaces have a number of electrical and / or electronic devices that produce heat which then flows into the environment. These devices include computers, printers, monitors, copiers, shredders or fax machines.
  • computers, printers, monitors, copiers, shredders or fax machines are z. B. used in open-plan offices numerous such devices, the room temperature increases significantly. In addition, the temperature in the immediate vicinity of such devices is increased, which is uncomfortable for a person who works with these devices.
  • dealer workstations in which in a first area of a piece of furniture computers are housed and in a second area of the furniture monitors ( CH-A-666 170 ).
  • the devices are cooled by a cooling unit that cools the warm air from the first area and releases the cooled air into the second area.
  • the monitors are cooled, whereupon the heated air is returned to the room.
  • a cooling arrangement which comprises a piece of furniture and a cooling device, wherein the piece of furniture has an upper side and an area for receiving at least one heat-emitting device ( DE 201 08 669 U1 ).
  • the cooling unit communicates with its warm air inlet to the area, and the cold air outlet of the refrigerator includes an open directly to the environment opening upwards.
  • a side opening open to the environment is provided, and a flow resistance device is arranged in the side opening.
  • a base cabinet for a dealer's table which has a base cabinet with perforated doors in the footwell area (journal architecture, interior design, technical development, 12/2000, p. 174). Behind these perforated doors large filters are placed, through which air from the lounge of the dealer at extremely low speed enters the table and warms up on the installed computers and equipment. The warm air is then sucked by a cross-flow fan under the work surface and pressed by a cold water flowing through the heat exchanger. The filtered and cooled air then exits the device up through a grid into the room.
  • a device for ventilating lounges, especially office large rooms, known, with the total amount of air can be divided.
  • One part of the cold air is used to cool the whole room, whereas with the other part of the air an individual climate zone can be created ( DE 27 16 993 A1 ).
  • the heat-treated air is divided into at least two partial air streams, of which a first partial air flow above the table top and a second partial air flow below the table top are blown out.
  • the invention has for its object to provide an air conditioning device for workplaces, with which it is possible to provide each workstation individually with cooled and / or fresh air.
  • the invention thus relates to a cooling arrangement for a workstation table with a heat exchanger and at least one device to be cooled.
  • the heat exchanger provides cold air in a certain space, part of which is given to the environment and one part to the device to be cooled.
  • the discharged into the environment cold air is blown on the one hand in a kind of channel vertically upwards and on the other hand via two side channels monitors or persons who are employed at the workplace table supplied.
  • the advantage achieved by the invention is, in particular, that several areas of a workstation can be supplied with cooled air at the same time. Another advantage is that devices to be cooled are cooled by cold air so that they can not overheat.
  • a work table 1 with two worktops 2, 3 is shown.
  • the worktops 2, 3 are stabilized by two supports, of which in Fig. 1 only one support 24, 25 can be seen.
  • the workstation table 1 has, as shown here, two side walls 6, 7 and doors below the worktops 2, 3, with only the doors 4, 5 can be seen.
  • the side walls 6, 7 and the doors 4, 5 form a kind of cabinet.
  • a base 13 is arranged, which has a plurality of columns 14 to 17, 27, 53. At each of these rod-shaped columns 14 to 17, 27, 53 are pivot arms 18 to 20, to which in turn screens 11, 12, 54 are attached. By the pivot arms 18 to 20, the screens 11, 12, 54 can move into the person sitting on the work table 1 person in the optimum position.
  • the pivot arms for the screens 8 to 10 are hidden in FIG. 1.
  • a socket 26 On the base 13 and sockets are provided, of which a socket 26 can be seen. With 55 suction openings are designated, is supplied by the warm ambient air to a cooling unit.
  • the workstation table 1 has a plurality of slot-like openings 21, 22, 23, which extend over the entire width of the worktops 2, 3. These openings are preferably covered by grids. Below these grids, air control nozzles may be provided.
  • FIG. 2 shows a section along A-A through the workstation table 1 shown in FIG. 1.
  • a cooling device 30 shown only schematically here, which is arranged in the upper area of the table interior 31 , In the lower part of this table interior 31, two computers 46, 47 or other devices to be cooled are schematically indicated. The cold air flowing to the computers 46, 47 is shown symbolically by the arrows 50. Instead of two computers 46, 47, several computers can be provided.
  • FIG. 3 shows a section of the central region of the workstation table 1 according to FIG. 2.
  • the computers 46, 47 are not shown here.
  • the cooling device 30 which has two fans 35, 36 and two cooling units 44, 45. These chillers are centrally with a cooled liquid, z. B. cold water supplied. They absorb the warm air coming from computers 46, 47 and the environment, as indicated by arrows 48, 49 and 51, 52. The warm air 51, 52 around the monitors 9, 12 passes through the suction port 55 shown in FIG. 1, while the warm air of the computer 49 reaches the right side of the cooling units 44, 45.
  • the blower 36 thus blows upwardly cooled air.
  • the blower 35 thus blows cooled air down.
  • the warm air 51, 52 of the screens 9, 12 is sucked in via the openings 55 from the fan 35 and fed to the cooling units 44, 45.
  • the additionally heated by the screens 9, 12 air is thus removed directly from them, whereby the thermal load of the screens is reduced to a minimum.
  • nozzles 32, 33 are arranged, with which not only the strength of the air flow, but also the direction of the cold air, which comes from the space 43 and is passed through the hoses 34, 40, can be varied. For example, it is possible to direct the flow of air to the screens 9, 12 or to the persons seated on the work table 1. Each person can individually control the airflow.
  • the openings 21, 22 thus serve to set an individual climate, whereas the room climate is determined via the opening 23.
  • the nozzles 32 are preferably formed as the located on the ceiling of an aircraft nozzles with which the passengers can supply fresh air. In an arrangement of several jobs next to each other at least one pivotable nozzle 32 is provided per workplace, the air flow rate is adjustable. The flow cone is also changed by this nozzle 32.
  • the cool air blown down by the blower 35 serves to cool the calculators 46, 47 standing in the table interior 31, d. H. directly below the cooling device 30. Since the cold air is heavier than the rising warm air, it falls, so to speak, directly on the computer 46, 47. This ensures that the temperature inside the table 31 can be kept below 30 ° C. Overheating the computer is not possible.
