Disclosed herein are a refrigeration cycle device and three-way flow rate control valve. In a refrigeration cycle device including a compressor, first and second coolers configured to cool first and second storage compartments at least, respectively, and a mixer configured to mix refrigerants that have passed through the first and second coolers, a refrigerant flow path is switched so that refrigerants of first and second flow rates are circulated to the first and second coolers, respectively, while the first and second storage compartments are being cooled, and a refrigerant flow path is switched so that a refrigerant of a specific flow rate, which is smaller than a first flow rate but is not zero, is circulated to the first cooler after cooling of the first storage compartment is completed.

A refrigerator includes a main body defining a storage space, a cryogenic freezing compartment having an insulation space that is independent with respect to the storage space, an evaporator disposed inside the storage space to cool the storage space, and a thermoelectric module assembly disposed at one side of the cryogenic freezing compartment so that the cryogenic freezing compartment is cooled to a temperature less than that of the storage space. The thermoelectric module assembly includes a thermoelectric module, a cold sink coming into contact with a heat absorption surface of the thermoelectric module and disposed in the cryogenic freezing compartment, and a heat sink coming into contact with a heat generation surface of the thermoelectric module. The heat sink is cooled by introducing a refrigerant supplied to the evaporator.

A wide range cryoprocessor is disclosed which allows for the freezing and the thawing of bio-samples in a single unit, and at controlled rates. Improvements have been made to enhance freezing performance by switching the liquid nitrogen flow control to the extreme downstream side. A second feature has been added to the cryoprocessor, capability to raise the temperature of a sample environment to a user's requirements through the use of a flashed cryogen and heating that gas flow for use in the heat exchanger on the freezer.

There are disclosed a picking method (100) as well as an automated storage system (12) including a high-temperature zone and a low-temperature zone. The storage system comprises: at least one rack (30) including several rack levels (36) on top of each other and an aisle (32) laterally adjacent to the rack (30); a plurality of shuttle (50) in the aisle for storing and retrieving storage goods (70) in and from storage locations (42) of the at least one rack (30) and for horizontally transporting the storage goods (70); a stationary lifter (16) for vertically transporting the storage goods (70); and a tub (34) defining the low-temperature zone (52); wherein, in a height region of at least one of the rack levels (36), the tub (34): encloses, in a circumferentially closed manner, a group of contiguous storage locations (42) and the lifter (16); encloses closed downwards the group of contiguous storage locations (42); encloses closed, or closable, downwards the lifter (16); and is open upwards.

A refrigerator is provided. The refrigerator includes a freezing compartment, a refrigerating compartment, a quick-chilling chamber, and a compressor that supplies cold air to at least one of the freezing compartment, the refrigerating compartment, or the quick-chilling chamber. The quick-chilling chamber is cooled by first cold air introduced through the compressor or second cold air introduced through the freezing compartment.
