- the compressor is placed in the lower part of the body, the condenser is mounted next to the compressor or on the back wall, and the evaporator is housed inside the cold room.
- the evaporator is connected to the condenser and compressor through connecting pipes in insulating foam of the body.
- US 6,094,934 discloses a commercial freezer having a housing with a front wall, two side walls and an intermediate wall. An upper part of the front wall and the side walls extends over the intermediate wall to form a space for receiving a removable cooling module.
- the object of the invention is to provide a refrigeration device of a household refrigerator, which is modularly connected in a simple manner with the housing of the household refrigerator.
- a refrigeration device in particular a refrigeration cycle module for a household refrigerator, which is designed as a standalone refrigeration module with a complete refrigeration circuit for cooling a cold room of the household refrigerator and a separate housing in which at least one evaporator of Refrigeration circuit is arranged and includes the openings, passes through the air cooled by the evaporator and air to be cooled from the evaporator.
- Another aspect of the invention relates to a household refrigeration appliance with a cold room at least one cold room housing, on which a door leaf is arranged for closing the cold room, and the refrigeration device according to the invention, wherein the cold room housing has openings through the air cooled by the evaporator in the cold room and air from Cold room reaches the evaporator.
- the household refrigerating appliance according to the invention accordingly comprises the cold room housing, which limits the cold room.
- the cold room housing, on which the door leaf is struck for closing the cold room is designed in particular heat-insulating.
- the refrigeration device is not installed in the cold room housing, but is designed as an independent refrigeration module, which includes the complete refrigeration cycle. So that the air cooled by the evaporator can pass from the refrigerating module according to the invention into the refrigerating space, the refrigerating chamber housing and the housing of the refrigerating module have the openings through which the cooled air can circulate between the refrigerating module and the refrigerating space.
- the refrigeration device designed as a refrigeration module can be relatively easily removed, e.g. to be replaced by another cooling module.
- the refrigeration device according to the invention can be designed such that their components are relatively easily accessible to the service person, which has a positive effect on the service cost.
- the brazing and subsequent leak testing of the refrigeration cycle are the labor-intensive sections in the production of refrigerators.
- this part of the household refrigeration appliance can be produced in countries where, for example, the wages are relatively low, which are prerequisites for producing relatively inexpensive household refrigerators.
- the cooling module can preferably also have the complete control device for controlling the refrigeration cycle.
- the refrigeration module according to the invention may optionally be replaced more easily by a further refrigeration module.
- the refrigeration module is provided to arrange the refrigeration module on the cold room housing, in particular the
- Housing of the cooling module are executed in alignment, whereby a heat loss in the circulation of air between the cold room and the cooling module can be reduced.
- the cold module can be arranged on the outside of the ceiling of the cold room housing, in particular be releasably secured to the ceiling of the cold room housing.
- This embodiment allows a relatively simple releasable attachment of the refrigeration module according to the invention on Kälteraumgeophuse.
- the openings of the housing of the cooling module are aligned with the openings in the ceiling of the cold room housing, the openings of the cooling module are preferably arranged in the bottom of the housing for this variant.
- the evaporator may be oriented substantially horizontally.
- a channel is provided in which the evaporator is arranged and which extends to the openings of the housing.
- This configuration results in a relatively good circulation of the air between the evaporator and the cold room.
- the cooling module can have a condensation water compartment assigned to the evaporator which collects condensation water that may accumulate during operation of the evaporator.
- the refrigeration module may include a ventilator associated with the evaporator which blows cooled air through one of the openings of the housing into the refrigeration space and / or draws air from the refrigeration space through one of the openings of the housing ,
- the fan may in particular be arranged between the evaporator and the opening, through which the fan blows the cold air into the cold room.
- the fan is optionally arranged in the channel in which the evaporator is arranged.
- the housing has a particular heat-insulating chamber in which the evaporator is arranged and in which the openings of the housing end.
- the housing may then have a further chamber in which a condenser of the refrigeration circuit is arranged and which in particular comprises a further opening through which air heated by the condenser reaches the environment outside the housing.
- the two chambers can be separated by a heat-insulating partition. This results in conditions that the colder part of the refrigeration device, i. the chamber in which the evaporator is located from the warmer part of the refrigeration device, i. the chamber in which the condenser is arranged is separated by a heat insulation, whereby heat losses can be reduced.
- a compressor of the refrigeration cycle and / or a further fan may be arranged, which blows the heated air from the condenser through the further opening in the environment outside the housing. This makes it possible that the heat generated by the condenser is reliably released to the environment.
