Definitions
- the invention relates to a refrigerator with a normal cold room and a freezer compartment, in which the compressor provided with a control device contains the refrigerant introduces via a capillary tube into a tube section, which the evaporator of the freezer compartment.
- refrigerators of this type The problem with refrigerators of this type is to freeze the freezer compartment the evaporator to supply the required cooling capacity and on the other to ensure that the normal cooling room has the required cooling capacity Plate is fed, which is so large that it is sufficiently large Dehumidification surface forms, and beyond that the normal cold room only that supplies the required cooling capacity, which prevents the temperature from falling too low.
- EP 0 758 732 A2 deals with this problem and proposes a solution a cooling device of the type specified above, in which the evaporator from two evaporator sections connected in series with the refrigerant leading Pipe sections exist, the evaporator section assigned to the normal cooling space consists of a plate of good heat-conducting material, the Size is designed for the area required for dehumidification, and the plate is connected to the pipe section carrying the refrigerant such that it with essentially the same temperature distribution that required for the normal cold room Cooling power is supplied.
- a disadvantage of the known cooling device is that a portion of the evaporator parts forming a closed coil, the freezer and the Normal cold room is assigned so that a connection consisting of two lines exists between the two sections, and that a coupling of the the pipe section forming the normal cold room evaporator to a cooling and dehumidifying plate is difficult because the normal cold room evaporator is formed Pipe section is still at a relatively low temperature.
- the object of the invention is therefore to provide a cooling device of the type specified to create, in which the cooling and dehumidifying plate assigned to the normal cold room simpler design and easier to train so large that a enough dehumidification area created and the normal cold room required cooling capacity is supplied.
- this object is achieved in that the evaporator Pipe section only the freezer and the normal cold room a refrigerator and Dehumidification plate is assigned, at least in the heat-conducting connection with parts or portions of that from the evaporator of the freezer the compressor running suction pipe, in which at least part of it The length of the capillary tube runs.
- the cooling device there is an extended section of the Intake pipe at least partially in heat-conducting connection with that of the normal cold room assigned cooling and dehumidifying plate so that it lengthened Section forms a heat exchanger with the capillary tube.
- the suction pipe gives due to the back flow of refrigerant vapor a sufficient cooling capacity from the cooling and dehumidifying plate.
- the suction pipe is at a higher temperature level than an evaporator pipe section, is the coupling of the suction pipe to the cooling and dehumidifying plate easier. This coupling can be done by gluing, soldering or welding or also by clamping with from the cooling and Dehumidification plate cut out and bent tongues take place.
- a roll or Z-bond board can also be used as a cooling and dehumidifying plate be provided.
- the capillary tube laid in the suction tube at least a part of it Emits heat to the intake manifold or the returning refrigerant vapor, can be a colder at the injection point of the freezer compartment evaporator tube Refrigerants are released so that the cooling capacity in the freezer and thus the efficiency can be increased. This results in shorter compressor runtimes and thus a reduced energy consumption.
- Dehumidification plate results from the supply of heat via the capillary at the beginning the standing time is shortened because defrosting is completed faster, and thus shorter run times for the compressor. This means that the compressor works with better efficiency because it works for shorter times in one thermodynamically unfavorable range works. The result of shorter terms is less energy consumption and less temperature fluctuations in the device.
- the evaporator 1 assigned to the freezer compartment consists of a plate 2 which is used for Adaptation to the freezer compartment can be bent in a U-shape, as it is in EP 0 758 732 A2 is shown. With the plate 2, the evaporator coil can be in any To be connected wisely.
- the evaporator plate 2 can also be trade a roll or Z-bond evaporator board into which the evaporator coil is embossed.
- the intake coil 4 is connected to the the cooling and dehumidifying plate 5 associated with the normal cooling space is coupled is.
- the coupling can be done by individual soldering or welding points, not shown or also by means of a clamp with the plate 5 bent out Tongues are made.
- the intake manifold 4 runs in the dash-dotted line Way the capillary tube 6, which at the injection point 7 in the straight section 8th of the evaporator tube opens.
- the end of the straight evaporator tube section subsequent pipe coil opens in the manner shown in the Intake pipe 4.
- Section A-A shows the course of the capillary tube 6 in the suction tube 4.
