Abstract: A refrigerator having an air processing apparatus includes a first cabinet including a storage compartment and second cabinet mounted at one surface of the first cabinet includes an inlet hole and an outlet hole, a blower fan to blow the air drawn into the inlet hole towards the outlet hole, and a filter unit to filter the air drawn into the second cabinet via the inlet hole. A first PCB includes a first control unit to control at least one of a compressor and a pressure regulator, and a second PCB includes a second control unit to control the blower fan. A first mounting unit at one surface of the first cabinet defines a predetermined space which can accommodate the first PCB, and a second mounting unit at one surface of the second cabinet defines a predetermined space which can accommodate both the first PCB and the second PCB.

Abstract: A refrigerator may include a body having a freezing chamber and a refrigeration chamber, a cooling circuit for cooling the freezing chamber and the refrigeration chamber, and a power source for supplying power to the cooling circuit. The refrigerator may further include a thermosyphon provided between the freezing chamber and refrigerating chamber. A control circuit may be connected to the thermosyphon to control a flow of refrigerant in the thermosyphon. The control circuit may include a valve provided on a circulation path of the thermosyphon, a electrical power storage device connected between the power source and the valve, and a switching circuit provided between the valve and the electrical power storage device. When the power source does not supply power to the cooling circuit, the control circuit may operate the thermosyphon using power stored in the electrical power storage device.

Abstract: A refrigerator includes a cabinet, a first inner case that defines a freezing compartment, a second inner case that defines a refrigerating compartment, a thermal siphon unit that is configured to carry a working fluid for heat transfer and that has a closed loop shape that includes a first part arranged at an outer side of the first inner case and a second part arranged at an outer side of the second inner case, and a cool air storage unit arranged in a space partitioned in the first inner case. The cool air storage unit is configured to accommodate cool air of the freezing compartment and transfer the cool air to the first part of the thermal siphon unit arranged outside of the first inner case.
