Definitions

  • the invention relates to a refrigeration device with a fan.
  • a fan in the interior of the refrigeration device for example in a cooling room, generates an air flow which has an inhomogeneous flow speed due to dynamic components in the air flow.
  • dynamic components cannot usually be fully used in the refrigeration device, but only lead to a slight increase in the pressure jump in the flow generated by the fan.
  • the unused kinetic energy of the dynamic components can lead to unwanted noise emissions and reduce the energetic efficiency of the fan.
  • an undesired inhomogeneous flow can arise in air channels that are supplied on the pressure side by the fan, which can lead to uneven air velocities on an outflow side of the air channels. These uneven air velocities result, for example, in an inhomogeneous temperature distribution in the refrigeration device.
  • the inhomogeneous flow through the air channels generates resonances and excitations of the air channels and a fan housing.
  • a conventional fan housing is used to separate the air flow of the fan into several parts, for example for several compartments or areas to be supplied in the refrigeration device.
  • the dynamic, kinetic components of the air flow can lead to the aforementioned vibration excitations of the housing. The resulting noises accordingly reduce the efficiency of the fan in the refrigeration device.
  • JP 2001 066 039 A shows a refrigeration device comprising a fan which is arranged above an evaporator and blows air cooled by the evaporator into an interior of the refrigeration device.
  • the disclosure document JP 2003 240 408 A shows a refrigeration device comprising a fan which is arranged in a pressure chamber. To the left and right of the pressure chamber, air ducts comprising openings for outflowing air extend.
  • the disclosure document JP 2006 183 892 A shows a refrigeration device comprising a fan which is arranged in a pressure chamber. The pressure chamber has a recess.
  • JP 2000 180 035 A shows a refrigeration device comprising an evaporator.
  • a fan is provided above the evaporator, which blows air cooled by the evaporator through outlets of a fan cover into an interior of the refrigeration device.
  • the invention is based on the knowledge that the recovery of dynamic pressure components in an air flow of a fan to increase the total pressure jump can be dispensed with. Instead, it is proposed to create an air pressure chamber which enables the flow generated by the fan to flow out of this air pressure chamber without dynamic components.
  • the invention relates to a refrigeration device with a fan.
  • the fan is arranged in an air pressure chamber.
  • the air pressure chamber allows air currents generated by the fan in the air pressure chamber to be balanced out, so that dynamic components of the air flow result in a uniform total pressure in the air pressure chamber, thereby creating a homogeneous pressure or a homogeneous air flow.
  • This enables an air flow that is homogeneous with regard to the air speed to be tapped at suitable points of the delimitations, for example walls of the pressure chamber.
  • the homogeneous air flow reduces the noise generated by the fan, in particular by stimulating air ducts or other components of the refrigeration device.
  • the air pressure chamber has a corresponding volume, which supports the formation of the homogeneous air flow and the absorption of dynamic components in the air flow.
  • the fan is for example enclosed, in particular completely enclosed, by the air pressure chamber.
  • the fan can, for example, have a free-running impeller.
  • the fan can be manufactured with less effort.
  • the fan is designed, for example, as an axial fan or a radial fan or a tangential fan.
  • the air pressure chamber has an inflow opening for supplying air to the fan and two outflow openings for discharging air from the air pressure chamber. Accordingly, air can only enter the air pressure chamber through the inflow opening.
  • the air in the air pressure chamber can only be supplied via the fan.
  • air can only leave the air pressure chamber in the form of the air flow generated by the fan through the two outflow openings. This is improved ensures that the homogeneous air flow can arise in the air pressure chamber.
  • the fan is arranged with respect to the inflow opening in such a way that a pressure side of the fan is separated from a suction side of the fan.
  • the fan is arranged above and / or within the inflow opening.
  • the fan is positioned in the interior of the air pressure chamber above the inflow opening in such a way that a suction side of the fan in particular completely covers the inflow opening.
  • the fan can also protrude into the inflow opening.
  • the inflow opening is arranged on one side of the air pressure chamber, which is in the extension of an axis of rotation of the fan.
  • the inflow opening is a circular opening in the side or the wall of the air pressure chamber, the axis of rotation of the fan running centrally through the inflow opening.
  • a symmetrical air supply is thus provided on the fan.
  • the at least one outflow opening is arranged radially to an axis of rotation of the fan or an extension of the axis of rotation.
  • the at least one outflow opening is arranged in a side that is in the direction of the air flow generated by the fan. Accordingly, the outflow opening is arranged, for example, away from the axis of rotation or the extension of the axis of rotation.
  • an air duct is connected to the at least one outflow opening.
  • the air duct is used, for example, to forward the air flow to one or more areas in the refrigeration device which are in particular arranged at a distance from the fan or the air pressure chamber.
  • the air duct has, for example, at least one opening to a cooling space of the refrigeration device. It is also possible for the refrigeration device to have a plurality of, in particular independent, cooling spaces which are supplied with the air flow generated by the fan via corresponding openings in the air duct.
  • the air pressure chamber has two outflow openings.
  • the two outflow openings are opposite one another with respect to an axis of rotation of the fan.
  • the air flow generated by the fan is evenly distributed over the two outflow openings.
  • the outflow openings are directly opposite one another, so that, for example, a connecting line between the outflow openings runs in a straight line through the axis of rotation.
  • the air pressure chamber prefferably has a first leg and a second leg.
  • One of the two outflow openings is arranged at the end of the first leg, and the other of the two outflow openings is arranged at the end of the second leg.
  • the first leg and / or the second leg run past the axis of rotation of the fan.
  • the air pressure chamber is shaped in such a way that there is an angled or curved or S-shaped connection between the two outflow openings.
  • the first and the second leg can, for example, run parallel to one another.
  • the leg arrangement described enables flexible positioning of the outflow openings on the air pressure chamber.
  • one side of the air pressure chamber is formed by a wall, in particular a rear wall, of a cooling space of the refrigeration device.
  • the air pressure chamber can be provided in the refrigeration device with reduced material expenditure.
  • the fan is held by a fan holder which is fastened to the said wall of the cooling space.
  • the fan is screwed to the wall of the cold room, for example.
  • Such an attachment of the fan holder to the wall which usually has a greater mass than the fan holder, can stimulate the housing parts of the refrigeration device be reduced. This results in fewer vibrations and noise, which are disruptive or reduce efficiency.
  • an air supply is provided on the fan which has a blockage of less than 20%, in particular less than 10%, of an inlet area of the fan.
  • Air is preferably supplied to the fan symmetrically, that is to say without blocking.
  • the efficiency of the fan is only slightly reduced if there is an asymmetrical blockage of the air supply to the fan and less than 20% of the total supply area, preferably less than 10%, of this area.
  • a high-efficiency fan can be used in the air pressure chamber under various installation conditions of the air pressure chamber.
  • the air pressure chamber has at least partially rounded outer walls.
  • such roundings can be provided in areas of the air pressure chamber which would form a corner or edge without the rounding.
  • so-called dead water areas can arise during the ventilation of moist air, which are prevented by the rounding. This is particularly advantageous in the case of air pressure chambers with a small volume.
  • the deliberate renouncement of the recovery of dynamic components for the entire pressure increase means that part of a theoretically possible pressure jump of a fan system is dispensed with, but the homogeneous distribution of the air in the air pressure chamber or in the pressure-side ducts connected to it are fewer Pressure loss caused in the entire air system and temperature inhomogeneities due to inhomogeneous outflow of air avoided.
  • This enables the energetic efficiency of refrigeration devices, in particular circulating air refrigeration devices, to be increased.
  • refrigeration devices with forced convection with an air pressure chamber according to one of the embodiments described can be designed in a simplified manner according to modular aspects and thus less cost-intensive.
