Abstract
A freezing refrigerator heats an entrance side pipe of evaporator, which is difficult to heat in the related art, with the condensation latent heat of refrigerant that builds up in a lower portion of evaporator in a liquid state while being vaporized with the heat of defrosting heater so as to warm the outlet pipe by a second thermal coupling part thermally coupling an inlet pipe and an outlet pipe of evaporator, whereby temperature variation of the entire evaporator in a defrosting operation can be suppressed, and the power consumption of defrosting heater can be reduced.
Claims6
A freezing refrigerator comprising:
- a compressor;
- a condenser;
- a dryer;
- a decompressor;
- an evaporator;
- a first pipe including an inlet pipe of the evaporator;
- a second pipe including an outlet pipe of the evaporator;
- a first thermal coupling part configured to thermally couple the decompressor and the second pipe together;
- and
- a second thermal coupling part configured to thermally couple the first pipe and the second pipe together, wherein
- the compressor, the condenser, the dryer, the decompressor and the evaporator configure a refrigerant cycle.
