Abstract: Provided are a magnet gasket and a cooling apparatus which enhance thermal insulation performance. The cooling apparatus includes: a thermal insulation box that has an opening end surface enclosing the opening and facing frontward; a door capable of opening and closing the opening; and a magnetic gasket attached to an inside peripheral portion of the door facing the opening end surface while the opening is closed, the magnetic gasket having: a magnet; a magnet retaining part; and a heat insulation sheet being provided between the magnet and the magnet retaining part and being provided, in a closed state in which the opening is closed by the door, on a side portion on a side of the door on a peripheral surface of the magnet and on a side portion facing an inner side in a width direction in the closed state on the peripheral surface of the magnet.

Abstract: A refrigerator includes: a compressor; an evaporator; a main condenser; a dew-prevention pipe; a bypass provided in parallel with a first channel from the main condenser to the dew-prevention pipe, and connected with the evaporator; a switching section provided on a downstream side of the main condenser, in which the switching section opens and closes the first channel, and a second channel from the main condenser to the bypass; and a control section. When defrosting the evaporator, the control section operates in such a manner that a refrigerant staying in the evaporator, the dew-prevention pipe, and the bypass is collected in the main condenser by closing the first channel and the second channel during an operation of the compressor, and thereafter, a high-pressure refrigerant collected in the main condenser is supplied to the evaporator through the bypass by stopping the compressor and opening the second channel.

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.
