Abstract: A vacuum adiabatic body includes a heat exchange pipeline and a sealing plug. The heat exchange pipeline includes at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces. The sealing plug allows the heat exchange pipeline to pass through a first point of the first plate and a second point of the second plate without contacting a third space.

Abstract: The refrigerator includes a compressor compressing a refrigerant, a condenser condensing the refrigerant compressed in the compressor, and a dryer in which the refrigerant condensed in the condenser is introduced. The dryer removes impurities or moisture of the refrigerant. A flow adjustment part is provided on an outlet-side of the dryer to switch or control a flow direction of the refrigerant. A plurality of evaporators is connected to the flow adjustment part, and the plurality of evaporators includes a first evaporator and a second evaporator. A first refrigerant passage extends from the flow adjustment part to the first evaporator, and a second refrigerant passage extends from the flow adjustment part to the second evaporator. A guide tube extends from the dryer to one side of at least one evaporator of the plurality of evaporators to guide the refrigerant to be cooled.
