A temperature control system is positioned in the upper compartment and includes an air passage. A lower inlet opening extends through a front surface of the vertical partition to the air passage. A damper assembly includes a door that is moveable between a first position and a second position. When the door is in the first position the door fluidly isolates the through passage in the partition from the upper compartment while allowing the lower inlet opening in the vertical partition to fluidly communicate with the air passage in the vertical partition. When the door is in the second position the door fluidly isolates the lower inlet opening from the air passage while allowing the through passage to fluidly communicate with the upper compartment.

Provided are a refrigerator and a control method thereof. The refrigerator according to the embodiment includes a compressor configured to compress a refrigerant; a condenser configured to condense the refrigerant compressed by the compressor; a flow control part disposed at an exit side of the condenser to switch a flow direction of the refrigerant condensed by the condenser; a plurality of branch pipes configured to extend from the flow control part; an expander installed at the plurality of the branch pipes to depressurize the refrigerant; a plurality of evaporators connected to the plurality of branch pipes; and a bypass pipe configured to extend from an exit side of one of the plurality of evaporators to an entrance side of the other evaporator and having a bypass expander installed thereat to depressurize the refrigerant.

Embodiments of the present disclosure include methods, apparatuses, and systems for cooling. Embodiments include a cooling system comprising a mobile container, conveyor system, and sensor feedback system. Container includes at least a first, second, and third section.
