A refrigerator including a cabinet including an insulator provided between an inner case and an outer case, a cold air duct embedded in the insulator to circulate cold air through the storage compartment, a cooling module mounting unit provided at a lower portion of the cabinet, and a cooling module including a module body in which an evaporator, a condenser, a compressor, and a cooling fan are installed and having an accommodating portion to accommodate the evaporator in a lying state, the cooling module being provided with a connection opening communicating with the cold air duct when mounted on the cooling module mounting unit.

A cryogenic freezer features a dewar defining a storage space. A reservoir is positioned within or adjacent to the storage space and is configured to contain a cryogenic liquid with a headspace above the cryogenic liquid in a reservoir interior space that is sealed with respect to the storage space. A refrigeration module is in heat exchange relationship with the reservoir. A sensor is configured to determine a temperature or pressure within the reservoir. A system controller is connected to the sensor and the refrigeration module and configured so that the refrigeration module is adjusted to provide additional cooling to the reservoir when a pressure or temperature within the headspace increases.

A drawer includes insulation defining a climate-controlled insulated interior of the drawer, and a refrigeration system. The interior of the drawer may be divided into compartments having lids, and actuators may be provided for unlocking the lids. The actuators may include solenoids, which may be disposed outside the climate-controlled interior of the drawer. The drawer may include an air inlet, an outlet, and a fan. The fan may draw air through an air flow path defined at least in part by the insulation.

A refrigerator includes a body including at least one storage compartment and a cooling module accommodating space, a door to open and close the storage compartment, and a cooling module accommodated in the cooling module accommodating space. The cooling module may include a heat radiating part, a heat absorption part, and a cooling module barrier to separate the heat radiating part and the heat absorption part. The heat radiating part may be disposed eccentrically on one of lateral sides of the cooling module and the heat absorption part may be disposed at a lateral side of the heat radiating part.
