- the invention is suitable for exchange jobs in which two jobs, such as two dealer tables, are placed back to back.
- the invention is also suitable for workplaces, which are arranged side by side and form, for example, a C or arcuate workstation arrangement in a juxtaposition.
- DE 10 2005 038 719 A1 discloses a cooling arrangement for a workstation table with two worktops and a base arranged therebetween with holders for monitors and with a heat exchanger in a cabinet below the worktops.
- the heat exchanger is supplied with heated ambient air through openings in the base and exhaust air from the computers arranged in the cabinet.
- the cooling air out The heat exchanger is divided by a divider with two fans in two air streams, wherein an air flow is discharged through controllable nozzles in the environment and also in the direction of monitors, while the second air flow is directed to the computer.
- the invention is based on the invention to provide workstation arrangements with a heat exchanger, which efficiently ensure the required cooling of the computer equipment and also a pleasant working environment for the employees both for a workstation and for two or more workplaces.
- a basic idea of the invention is to achieve effective cooling of computer equipment in a receiving space of a workstation arrangement by means of a heat exchanger and forced air convection.
- a corresponding construction of the workstation arrangement which is advantageously designed as a double workstation with two back-to-back workstations, or can have one, two or more laterally adjacent workstations, a controlled and direct guidance of the cooling air cooled in the heat exchanger to the EDP Devices achieved.
- a first workstation arrangement in which below a working plane a receiving space for Computer equipment and a heat exchanger is formed, wherein the heat exchanger is an air-fluid heat exchanger and received the heat loss of the computer equipment from a guided through the computer equipment air flow and in the heat exchanger to the fluid and to the outside, namely outside of the Installation space of the workplace arrangement, dissipated, an almost airtight receiving space.
- the receiving space an exhaust air area for discharging the heated exhaust air from the computer equipment is provided, from which the exhaust air passes into the heat exchanger.
- a supply air region is formed at least underneath the EDP devices, through which the cooling air cooled in the heat exchanger is guided and passed directly to the EDP devices.
- the cooling air is controlled by a Zu Kunststoff Scheme, which is formed by a double floor construction or with the help of an intermediate floor, reaches the computer equipment.
- the cooling air space formed by the intermediate bottom is thus located below the EDP devices and contributes to their cooling.
- Essential is the direct supply of cooling air through the air inlet side of the computer equipment.
- the cooling air passes from the horizontal cooling air space via an opening in a vertical cooling air space, which is formed between the air inlet side of the computer equipment and a front door or wall of the receiving space.
- a vertical cooling air space which is formed between the air inlet side of the computer equipment and a front door or wall of the receiving space.
- the exhaust air area is separated from the vertical cooling air space by ventilation technology.
- panels or partitions can be arranged, which prevent a mixing of the cooling air flow with the exhaust air.
- the workstation arrangement is particularly suitable for a double workstation, which is formed by two workstations, for example, two dealer tables.
- the two workplaces are arranged close to each other on the rear side, a distance being covered by a cover which can connect the table tops of the two workstations on the back.
- the receiving space with the computer equipment, which are primarily personal computers, and with the heat exchanger is then from the corresponding areas of the two table tops of the workstations, end walls and front doors and / or walls of the workstations, from the intermediate floor and from limited to the cover.

- the inventive lateral arrangement of the heat exchanger prevents damage to the computer equipment. It is also advantageous that the cooling can take place below the dew point, for example with a direct evaporator.
- the lateral arrangement of the heat exchanger and the pair of fans and the horizontal air duct in a vertical cooling air space and a vertical exhaust air space which is expediently separated from the cooling air space by ventilation technology, possible in a particularly advantageous manner, the juxtaposition of at least two workstations and their cooling with a common heat exchanger and redundant fan pair.
- the second workstation then expediently adjoins the first workstation in the area of the heat exchanger and the redundant fan pair.
- the cooling air spaces of the two workplaces or the reception rooms are adjacent to each other, as are the exhaust air rooms.
- each a transition opening is formed with a corresponding seal, the cooled in the heat exchanger of a first workplace air with the help of the redundant fan pair can be pressed both in the vertical cooling air space of the first workplace and in the vertical cooling air space of the second workplace.
