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 method for controlling a refrigerator comprises: as a first refrigeration cycle for refrigeration of a first storage chamber is operated, operating a compressor and operating a first cold air supply; when the first refrigeration cycle has been operated for a first run time, converting to a second refrigeration cycle for refrigeration of a second storage chamber, and operating a second cold air supply; and if the second refrigeration cycle has been operated for a second run time, stopping the second refrigeration cycle. A first reference time is determined using a representative value obtained based on the temperature of the first storage chamber during a single run cycle, which includes a previous first refrigeration cycle and a previous second refrigeration cycle. A second reference time period is determined using a representative value obtained on the basis of the temperature of the second storage chamber during the single run cycle.

The method for controlling the refrigerator includes operating a first cooling cycle for cooling the first storage compartment to operate the compressor and operating a first fan for the first storage compartment, and switching the first cooling cycle to a second cooling cycle for cooling the second storage compartment to operate the compressor and operating a second fan when a stop condition of the first cooling cycle is satisfied. A temperature of each storage compartment is sensed at sampling time intervals in each cooling cycle. Further, a cooling power of the compressor is determined for each sampling time based on a sensed current temperature of the storage compartment, and the compressor is operated at the determined cooling power.

In addition, the thermoelectric element may be a cascade type thermoelectric element in which two thermoelectric elements having the same or different specifications are coupled to each other.

A refrigerator according to an embodiment of the present invention comprises an inlet port and an outlet port which are formed in a sink body forming a heat sink, so as to guide coolant inflow and coolant outflow respectively, wherein the center line of the inlet port passes through the center of a thermoelectric element attached to the heat sink.

In a refrigerator control method according to an embodiment of the present invention, an operation corresponding to a freezer chamber load is performed when a heat load penetrates the inside of the freezer chamber, and the internal temperature of a deep-freezing chamber is differently set and controlled according to the on/off state of a deep-freezing chamber mode, and thus the input condition of the operation corresponding to the freezer chamber load can be differently set according to the on/off state of the deep-freezing chamber mode.

A stand-alone ice and beverage dispenser is provided. Appliance includes a cabinet defining a chilled chamber, a bottom portion and a countertop. Appliance includes an ice maker assembly mounted on the countertop, a liquid dispenser assembly mounted on the countertop, and a sealed refrigeration system. Sealed refrigeration system includes a compressor, condenser, chamber evaporator, and an ice maker assembly evaporator fluidly coupled through a refrigerant conduit. The compressor is operably coupled to the refrigerant conduit for circulating a flow of refrigerant through the refrigerant conduit. Appliance also includes refrigerant valve assembly including one or more valves. Refrigerant valve assembly is configured to selectively provide refrigerant to chamber evaporator to refrigerate chilled chamber and selectively provide refrigerant to the ice maker assembly evaporator for ice production.

Exemplary embodiments provide a refrigeration system having an interior space cooled by a plurality of cooling. Each cooling unit is capable of operating either synchronously when in communication with a control panel or under independent operation. Each cooling unit is modularly and replaceable without the use of tools by means of a quick connect system. The cooling units use a heat exchanger cooled by chilled water and make use of an electronic super heat control and electronic expansion valve to regulate the flow of refrigerant for improved efficiency.

A refrigerator includes an outer wrapper, a fresh food compartment defined by a liner within the wrapper and separated from an interior of the outer wrapper at least along a first side wall of the fresh food compartment to define a void, and a door at least partially enclosing an opening to the fresh food compartment when in a closed position. A door compartment is positioned along the door. The refrigerator further includes an evaporator compartment positioned at least partially within the fresh food compartment and a duct in fluid communication with the evaporator compartment at a first end thereof and in communication with the door compartment a second end thereof. The duct has a first portion that extends laterally from the first end along a portion of the evaporator compartment and a second portion extending through the void along the first side wall of the fresh food compartment.

An apparatus for preserving biological products comprising an inner housing arranged within an outer insulated housing, wherein walls of the inner housing define a compartment for receiving biological products, said walls comprising an inlet wall for inflow of a heat exchange fluid into the compartment, an opposed outlet wall for outflow of a heat exchange fluid out of the compartment, side walls and a base, the side walls and base adjoining the inlet wall to the outlet wall, wherein the inlet wall and outlet wall each include a series of apertures to accommodate a continuous heat exchange fluid flow through the apparatus such that, in operation, biological products received in the compartment of the inner housing are immersed in the heat exchange fluid to exchange heat with the heat exchange fluid.
