Definitions

  • the present invention relates to a refrigerator with at least one storage compartment and a refrigerant circuit comprising an evaporator for cooling the storage compartment, and an evaporator for such a refrigeration device.
  • Such evaporators conventionally include a circuit board on which a refrigerant line extends in loops from an injection point to an outlet point.
  • the loops are usually regularly arranged in successive installation orientation of the evaporator from top to bottom, so that when at the beginning of a cooling phase refrigerant is injected into the evaporator, the liquid refrigerant and with him the cooling effect only gradually from top to bottom over the entire evaporator surface spreads. Several minutes may pass before the entire evaporator surface has cooled evenly. This effect is all the greater, the larger the circuit board of the evaporator and / or its conduit length and the more intense the heat exchange at the surface of the evaporator.
  • Object of the present invention is to provide a refrigerator with improved energy efficiency and suitable for such a refrigerator evaporator.
  • the object is achieved on the one hand by the fact that in a refrigerator with at least one storage compartment and a refrigerant circuit comprising an evaporator on the
  • Evaporator at least two the one storage compartment cooling line sections are formed, which are connected in parallel in the refrigerant circuit and spaced from each other
  • both line sections are simultaneously supplied with liquid refrigerant upon activation of the refrigerant circuit; because they have spaced centers of gravity, theirs focuses
  • the spacing of the centroids should therefore be at least greater than the ratio of the surface area of the evaporator to the length of the refrigerant line extending thereon.
  • the separation of the line sections may be such that a boundary can be drawn on the evaporator between regions cooled by one and the other of the line sections, which is not longer than the sum of the edge lengths of the evaporator.
  • the cooling effect initially is expedient for the cooling effect initially to be used in regions of the evaporator which are at a distance from one another and from there to spread over the evaporator surface.
  • the line sections are expediently arranged so that on at least one of the line sections, the line length between an upstream starting point of the power section and the farthest from a center of the evaporator point of this line section is shorter than the line length between the farthest from the center of the evaporator point and a downstream end point of the same line section.
  • a branch forming an upstream starting point of the pipe sections is preferably arranged on a circuit board of the evaporator itself. So only a single supply line to the evaporator board must be connected to supply all line sections with refrigerant. In a corresponding manner, it is expedient for the discharge of the refrigerant that a confluence, which forms a downstream end point of the line sections, is likewise formed on the evaporator plate.
  • the object is further achieved by an evaporator for a refrigeration device in which line sections connected in parallel to a common injection point are arranged on an evaporator plate.
  • Fig. 1 is a schematic representation of an evaporator according to the invention for a
  • Refrigerating appliance with a single storage compartment
  • Fig. 2 shows a second embodiment of the evaporator according to the invention.
  • Fig. 1 is a schematic plan view of an evaporator for a refrigerator with a single storage compartment, such as a refrigerator or freezer.
  • the evaporator can be joined together in a manner known per se to a person skilled in the art from a planar board on which a pipeline is attached as refrigerant channel 1, or a planar board and a board into which a refrigerant channel 1 is embossed.
  • the second alternative is preferred because it facilitates the production of a branched refrigerant channel, as described in more detail below.
  • At a junction in the upper left corner of the board leads leading to a compressor of the refrigerator suction line 11 to the refrigerant passage 1.
  • a guided in the suction line capillary 2 is inserted at an injection point 12 tightly into a bottleneck of the refrigerant passage 1.
  • the evaporator can, for example, in a rear wall of the Refrigerating device, between an inner container and an insulating foam layer, be mounted with the inner container facing planar board.
  • the invention is also applicable to an evaporator which is arranged in the inner container of a refrigerator and surrounds a freezing compartment there.
  • a branch 3 is formed in the refrigerant channel 1, at which the refrigerant flow is divided into two line sections 4, 5.
  • the line section 4 substantially fills the upper half of the evaporator plate and extends in several U-shaped loops to a confluence 6, where it again meets the line section 5.
  • the line section 5 extends from the branch 3, initially along the edges of the evaporator plate to a lower edge, from where it also forms a loop on the confluence 6.
  • the line length between the branch 3 and a point 7 and 8 of the line section furthest from a center C of the board is substantially shorter than the distance from point 7 or 8 to the confluence 6.
  • the distance between the centers of gravity 9, 10 of the line sections 4, 5 is many times greater than the distance d between adjacent parallel pieces of the line sections 4, 5 and thus significantly larger than the ratio of board surface to the total length of the refrigerant channels extending thereon. 1
  • Fig. 2 shows a second embodiment of the evaporator. While in the embodiment of Fig. 1, a clear distinction between a substantially cooled by the line section 4 upper half and a cooled only from the line section 5 lower half of the board is possible, such a clear separation in the embodiment of FIG. 2 is not given. Although here, too, the upper half of the evaporator plate is essentially cooled only by the line section 4, while the line section 5 along the top and right edges of the board on the shortest path of the lower half of the board strives, but extend in this lower half of the line sections 4, 5 largely next to each other.
  • the line sections 4, 5 are substantially equal in length
  • the line section 5 is significantly shorter than the section 4.
  • the line cross-section in the section 5 is smaller than in section 4. It can be chosen taking into account the lengths of the sections 4, 5 so that both sections 4, 5 have a same flow resistance.
  • the loops of the line section 5 extend to less than half of the board surface and also the lower board half is cooled in the stationary operating state via the line section 4, the flow resistance of the line section 5 but also higher than that of the line section 4th to get voted.
