Definitions

  • the disclosure relates to a refrigerator.
  • Patent JP4238731 B2 discloses a cooling cycle mechanism as a conventional refrigerator.
  • the cooling cycle mechanism is operated in such a way that a capillary tube installed in the middle of a pipe for introducing a refrigerant, which is discharged from a condenser, into an evaporator, and a suction pipe for introducing a refrigerant, which is discharged from the evaporator, into a compressor, are connected in parallel with each other, and thus the refrigerant flowing in the capillary tube exchanges heat with the refrigerant flowing in the suction pipe, thereby improving the efficiency of the cooling cycle.
  • the refrigerant flowing in the capillary tube has the highest temperature at the condenser side, and the temperature of the refrigerant is lowered as being away from the condenser.
  • the refrigerant flowing in the suction pipe has the lowest temperature at the evaporator side, and the temperature of the refrigerant is increased as being away from the evaporator.
  • the heat exchange is performed between a refrigerant having a relatively high temperature on the condenser side of the capillary tube and a refrigerant separated from the evaporator of the suction pipe, and at the same time, the heat exchange is performed between a refrigerant separated from the condenser of the capillary tube and a refrigerant having a relatively high temperature on the evaporator side of the suction pipe, and thus the heat exchange efficiency is only slightly improved.
  • a refrigerator including a cooling cycle mechanism having improved cooling cycle efficiency by more effectively performing heat exchange between a refrigerant discharged from an evaporator and a refrigerant discharged from a condenser. Additional aspects of the present disclosure will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the present disclosure.
  • the heat exchanger of the second pipe may be installed to extend from an end of the evaporator side to the compressor side.
  • the heat exchange efficiency may be further improved and the efficiency of the cooling cycle may be improved.
  • the heat exchanger of the first pipe and the heat exchanger of the second pipe may be arranged as follows. That is, the heat exchanger of the first pipe and the heat exchanger of the second pipe may be arranged in parallel to each other in the vertical direction, and the heat exchanger of the first pipe and the heat exchanger of the second pipe may be arranged in parallel in the horizontal direction.
  • the vertical direction is not limited to a perfectly vertical direction but includes a substantially vertical direction.
  • the horizontal direction is not limited to a perfectly horizontal direction, and includes a substantially horizontal direction.
  • the heat exchanger may be formed between the first pipe and the second pipe regardless of the arrangement of the devices constituting the cooling cycle mechanism. Accordingly, heat exchange may be performed between the upstream side in which the refrigerant flowing in the first pipe has a relatively high temperature, and the upstream side in which the refrigerant flowing in the second pipe has a relatively low temperature, thereby improving the heat exchange efficiency of the cooling cycle mechanism.
  • the intersecting position may include a state in which the first pipe and the second pipe intersect with each other while the first pipe and the second pipe are in contact with each other.
  • the first pipe may include an expander configured to expand the refrigerant, which is discharged from the condenser.
  • the expander may be a capillary tube constituting at least a part of the first pipe, and the heat exchanger of the first pipe may be constituted by the capillary tube.
  • the expander may be an expansion valve installed in the middle of the first pipe.
  • the refrigerator may further include an insulating member configured to cover at least a part of both the heat exchangers.
  • both the heat exchangers are arranged inside the insulating member, heat exchange is more efficiently performed between the refrigerants flowing in both the heat exchangers.
  • An outer wall of the refrigerator housing body may be used as the insulating member.
  • the insulating member may cover at least the upstream side of both the heat exchangers, and the insulating member may further cover a portion other than both the heat exchangers in the first pipe and the second pipe.
  • the heat exchanger may be arranged between a machine room in which at least one of the compressor and the condenser is placed and a cooling room in which the evaporator is placed.
  • the heat exchanger of the first pipe may be arranged on the machine room side, and the heat exchanger of the second pipe may be arranged on the cooling room side.

Accordingly, the heat exchange rate in the heat exchanger may be improved.

  • the heat exchangers 24a and 24b are formed in the middle between the first pipe P1 and the second pipe P2.
