Definitions
- the present invention relates to a refrigerator with a collecting and evaporation container for condensation according to the preamble of claim 1.
- a refrigerator is known from DE 198 55 504 A1.
- This known refrigeration device has a heat-insulating housing which encloses a storage space for refrigerated goods and has a recess open to the outside in a lower corner, in which a compressor for a refrigerant circuit of the refrigeration device is accommodated.
- a collecting container for condensation is mounted, which condenses in the storage chamber and runs through a breakthrough formed in the housing above the collecting container in the collecting container.
- the collecting container is mounted on the housing of the compressor in order to utilize heat loss, which the compressor generates during operation, in order to heat the condensation water in the collecting container and thus accelerate its evaporation.
- the object of the invention is therefore to provide a refrigeration device with a condensate evaporator, which ensures an effective evaporation of the condensation water which is neutral with regard to the energy consumption of the device.
- the object is achieved by a refrigeration appliance with the features of claim 1.
- the invention is based on the insight that a large part of the heat loss generated in the compressor is not dissipated by heat conduction within the compressor - only this is the part of the heat loss from which conventionally a part can be used by mounting the collecting container on the evaporator housing - but by the refrigerant itself.
- This waste heat is conventionally released to the environment of the refrigeration device through a condenser.
- the heat exchanger thermally coupled to the collecting container according to the invention allows at least some of this waste heat to be released to condensation in the collecting container.
- This heat exchanger is expediently incorporated between a high-pressure outlet of the compressor and the condenser, so that the latter can only release to the environment the portion of the residual heat that was not absorbed by the condensation water.
- the heat exchanger expediently has a pipeline through which the refrigerant flows and which is surrounded by the condensation water on at least part of its circumference.
- the pipeline is arranged so as to be immersed in the collecting container, so that it is surrounded on its entire circumference by the condensation water - provided the level in the collecting container is high enough.
- the pipeline is integrated in a wall of the collecting container.
- the collecting container For reasons of cost, it is preferred to manufacture the collecting container from plastic. In such a container, it is difficult to prevent the growth of bacterial mucus if there is constant condensation in it, with the result that unpleasant odors can be released.
- This problem can be solved according to the invention combat that the heat exchanger is at least partially made of a material that releases antibacterial copper or silver ions. This can be implemented particularly easily if the pipeline which is at least partially surrounded by the condensation water is a copper pipe.
- the collecting container is partly formed by a wall of the housing of the compressor and partly by a crown which is tightly mounted on this housing.
- the omission of an intermediate wall improves the heat transfer from the compressor housing into the condensation water
- a refrigerant outlet opening of the housing can be arranged on the part of the wall surrounded by the crown, so that a pipe going out from there is collected directly in the container Condensation runs.
- Fig. 1 is a schematic partial representation of a refrigerant circuit
- FIG. 2 shows a compressor with a condensation water tank mounted thereon according to a second embodiment of the invention.
- Fig. 3 shows a compressor with a condensation water tank according to a third embodiment of the invention.
- Fig. 1 shows a perspective and partially exploded part of the refrigeration cycle of a refrigerator according to the invention.
- the housing of the refrigerator itself has been omitted for the sake of clarity and, since it is known per se, is not described further.
- On a compressor housing 1 there are a suction connection 2, through which the relaxed refrigerant enters the compressor, and a pressure connection 3, through which the compressed refrigerant is expelled again.
- a defrost water container 4 is provided for mounting on the compressor housing 1 and has a recess 5 on the bottom which, in the assembled state, conforms to the upper part of the compressor housing 1 in order to waste heat emitted by the compressor in this area as completely as possible into the defrost water collected in the container 4 initiate.
- a pipe 6 is connected to the pressure connection 3. It extends in the form of a loop 7 initially through the defrost water container 4, so that the refrigerant contained therein can cool down in contact with the defrost water.
- the pipeline 6 is formed by a copper tube which, in contact with condensation water in the container 4, outputs copper ions thereon. These ions have a bactericidal effect which prevents or at least limits the growth of bacteria in the container 4.
- a subsequent second loop 8 runs on the front of the body of the refrigerator (not shown).
- the refrigerant emits heat in order to prevent exposed areas of this front side from being cooled to such an extent by heat conduction from the storage chamber of the refrigeration device that condensation forms here.
- a condenser 9 is connected to this second loop 8 in the refrigerant circuit.
- the condenser 9 is an essentially plate-shaped structure, in which the pipeline 6 meanders between a plurality of parallel metal wires 10 welded to it, which stiffen the condenser and increase its surface area for heat exchange.
- the condenser 9 is mounted in a manner known per se on a rear side of the refrigerator housing.
- a dryer Connected to the condenser 9 is a dryer, no longer shown in the figure, for trapping water contaminants in the refrigerant, a throttle, usually in the form of a capillary line, for relaxing the refrigerant, and an evaporator arranged in close thermal contact with the storage chamber. From the outlet of the evaporator, the refrigerant again reaches the suction port 2 of the compressor.
- Fig. 2 shows an alternative embodiment of the arrangement of the compressor housing and condensate tank.
- the defrost water container 4 'differs according to this embodiment differs from that of Fig. 1 in that the recess 5 is replaced by an opening in the bottom of the container 4 ', in which the upper part 11 of the compressor housing is tightly inserted. Since the insulating effect of the wall of the container is eliminated, a more intensive heat flow from the compressor directly into the water of the condensation water container 4 is possible.
- the suction connection 2 'and the pressure connection 3' are laid on the upper part 11 of the compressor housing 1, so that the pipeline 6 runs through the condensation water container 4 'as soon as it emerges from the compressor housing 1.
- This placement of the connections 2 ', 3' means that the section of the pipeline running from the evaporator to the suction connection 2 'also runs through the condensation water container 4' to some extent.
- this section can be provided with an insulating sleeve 12.
- FIG. 3 shows a third embodiment of the arrangement of the compressor housing and condensation water container, which can be interpreted as a modification of the embodiment of FIG. 2.
- the defrost water container 4 "is shown cut away here.
- a lower, cylindrical section 13 of the defrost water container 4" nestles close to one
- the seal can e.g. through extensive
- Compressor housing 1 outgoing pipeline 6 forms several spirally running
- Loops 7 " which are fastened to the inside of section 14.
- the loops 7" thus take on a supporting function for the defrost water container 4 ", so that its
- Wall material can be of low strength and stiffness.
