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.
