Definitions

  • the invention relates to a convector which can be retracted in the floor duct of a room and has a cuboid housing in which at least one heat exchanger and at least one fan are arranged, the fan generating an air flow through the heat exchanger.
  • the object of the invention is to improve a convector of the type mentioned in such a way that a high air outlet speed is achieved with simple construction, manufacture and assembly.
  • This object is achieved in that the fan is arranged behind the heat exchanger in the flow direction.
  • the heated or cooled air is not released into the room via the heat exchanger, but directly via the fan, a high air outlet speed is achieved, in particular vertically upwards into the room, so that an intensive mixing of the room air is achieved. It can also be achieved that the escaping air nestles against a wall due to the soander effect. Furthermore, it is certainly prevented that the escaping air is partially sucked in again by the same device. With the exception of the fan ejection, the entire device is encapsulated. The filter is located above the heat exchanger, which prevents dirt from accumulating.
  • an upper air inlet opening under which the heat exchanger is arranged, in particular with its broad side forming the inlet, is provided. It is also advantageous here if there is an air space below the heat exchanger through which the air which has passed through the heat exchanger flows to the fan.
  • the fan be a cross-flow fan extending over at least part of the convector housing space.
  • the rotor axis of the cross-flow fan should be arranged parallel to the longitudinal extent of the convector housing.
  • the outlet opening of the fan is arranged directly below the horizontal outlet opening of the convector.
  • Optimal flow conditions to avoid drafts in the room require compliance with or exceeding a minimum exit speed of the order of approx. 1.5 m / s.
  • Such outlet speeds are available at the fan outlet, so that for exergetic reasons (pressure loss, acoustics) the ejection takes place directly from the fan.
  • a high depth of air penetration into the room with a low noise level is achieved if the air outlet opening of the convector and / or the fan has convexly curved side edges.
  • a filter be arranged in front of the air inlet of the heat exchanger.
  • a compact design is achieved if the fan has two rotors with rotor axes arranged coaxially to one another and the fan drive motor is arranged between the rotors.
  • the convector forms a structural unit with its housing, of which two or more units can be arranged one behind the other, particularly in the longitudinal direction, in a floor duct.
  • Fig. 1 shows a vertical section through the convector
  • Fig. 2 is an isometric view of the convector module with the heat exchanger removed.
  • the convector 1 has a cuboid housing 2 with a convector module with two mutually parallel vertical longitudinal side walls 3, 4 and two mutually parallel end side walls 5, 6, and one Floor plate 7.
  • the housing is covered at the top by horizontal removable gratings, not shown, which are accessible.
  • An air inlet opening 10 and an air outlet opening 11 are arranged below that of the filter frame 8 and the upper edge 9 of the end wall 5, the air inlet opening 10 being made substantially larger than the air outlet opening 11, that is to say the air outlet opening 11 has only 1/10 to 1 / 3 the size of the air inlet opening 10.
  • a heat exchanger 12 is fastened in a lying position, that is to say it is installed in such a way that it is flowed through vertically in cross section of a width B greater than height H and a length greater than height, the Longitudinal direction of the heat exchanger runs parallel to the longitudinal direction of the entire convector.
  • an air space 13 remains below the heat exchanger, through which the room air passing through the heat exchanger reaches the suction opening of a fan 14, which runs as a cross-flow fan with its rotor axis longitudinally and thus parallel to the longitudinal extent of the heat exchanger 12 and the longitudinal extent of the convector is arranged.
  • a plurality of tubes R run through the heat exchanger 12 and are connected to a heat or cold source.
  • the fan 14 thus draws the room air through the heat exchanger 12 and leads it through its outlet through the air outlet opening 11 into the room.
  • an air guide grille 16 with a plurality of fins is fastened, which is preferably adjustable in order to adjust the direction of the air blown out by the convector.
  • the side edges 17, in particular the longitudinal side edges of the air outlet opening 11, are here convexly curved, as a result of which the side edges 17 ensure that there is little turbulence and therefore little noise when the air outlet occurs.
  • a filter can preferably be arranged between the filter or filter frame 8 and the inlet surface of the heat exchanger 12 be arranged so that dirt and dust cannot get into the convector. In addition, this is also prevented by the convector being closed all around except for the inlet and outlet openings. For this reason, the area between the air inlet opening 10 and the air outlet opening 11 is also closed in particular by a sheet metal.
  • FIG. 2 shows that the fan has two rotors 18 with rotor axes arranged coaxially with one another and the electric drive motor 19 is located between the two rotors.
  • FIG. 2 shows the convector module that is installed in the convector trough or that several convector modules can be arranged one behind the other in a floor duct.
