The present invention provides a refrigerator, comprising a storage compartment and a mixed air passage. Both ends of the mixed air passage have air inlets, the middle portion of the mixed air passage comprises a mixed air outlet communicating with the storage compartment, and the mixed air passage is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet. The refrigerator of this invention comprises a mixed air passage, so that the air in an area of the storage compartment with a relatively high temperature can enter the mixed air passage earlier than external air or the air in the storage compartment with a relatively low temperature. Then, the two air flows are blown to the storage compartment in a mixed manner, realizing even temperature distribution in the storage compartment.

An ice maker for mounting into a household cooling appliance includes a storage container for ice that is formed with an opening which is accessible from the top. A fan generates an air stream in the ice maker. An air guiding duct above the storage container is bounded by a first lateral duct wall, which is oriented in the depth direction of the ice maker and extends in the height direction, and is bounded by a second duct wall, which is a roof wall. The air guiding duct has a first opening towards the bottom so that an air stream escapes towards the bottom. The first opening of the air guiding duct is arranged offset viewed in the width direction of the ice maker so that the air stream exiting from the first opening of the air guiding duct flows along an outer side of the storage container.

A refrigerator is disclosed. The refrigerator includes a cabinet including a storage compartment, a cool air supply means configured to operate to supply cool air to the storage compartment, a temperature sensor configured to sense a temperature of the storage compartment, and a controller configured to control an output of the cool air supply means based on a difference between a set temperature and a current temperature sensed by the temperature sensor and increase or decrease in temperature of the storage compartment sensed by the temperature sensor at a predetermined time interval.

A storage apparatus according to an embodiment may include a body having a storage space of storage products and an air purifying module coupled to the body. The air purifying module may include a light emitting diode part disposed along a passage of air to provide ultraviolet light, and a filter part disposed adjacent to the light emitting diode part.

A cooling channel is provided for cooling goods to be chilled, in particular food or pharmaceutical products. The cooling channel includes a cooling tower having an inlet end and an outlet end; a driven conveyor belt on which the goods to be chilled are arranged such that they can be conveyed through the cooling tower from the inlet end to the outlet end; a housing surrounding the conveyor belt and forming a cooling zone in the region of the conveyor belt; a filter unit for filtering air; a cooling unit for cooling the cooling zone; and at least one fan that interacts thermodynamically with the cooling unit and that conveys cooled air from the cooling unit to the cooling zone.

A storage and dispensing system for storing and dispensing temperature sensitive items is provided. The system includes a storage chamber, a dispensing chamber, an electro-mechanical module, and a cooling system. The storage chamber has walls defining plural compartments formed integrally therein for storing the temperature sensitive items at an ultra-low temperature. Each compartment is formed as a cylindrical sector with an inclined bottom surface. The plural compartments are arranged circumferentially around a vertical axis and stacked together in one or more rows, thereby an individual temperature sensitive item is slidable out of a respective compartment to the dispensing chamber by gravitational force. The electro-mechanical module is configured to rotate the storage chamber about the vertical axis. The storage chamber does not include any mechanical or electrical components inside, which avoids the need for devices that can tolerate an extremely low temperature environment.

A refrigerator according to the present invention comprises: a storage compartment for storing food; a first temperature sensor for sensing the temperature in the storage compartment; a door for opening and closing the storage compartment; a cold air supply means for supplying cold air into the storage compartment; trays forming ice-making cells which are spaces in which water changes phase into ice due to the cold air; a second temperature sensor for sensing the temperature of the water or ice in the ice-making cells; a heater for supplying heat to the trays; and a control unit for controlling the heater, wherein, after opening or closing of the door is sensed during the ice-making process, the control unit increases the cooling power of the cold air supply means if an increase in cooling power therefrom is determined to be needed on the basis of the temperature sensed by the first temperature sensor, and decreases the amount of heat applied by the heater if a reduction in heat applied by the heater is determined to be needed on the basis of the change in temperature sensed by the second temperature sensor.

An evaporator for use in a refrigeration system includes one or more Coanda evaporation chambers having an integrated, internal expansion device. The internal expansion device is a linear atomization tube having a plurality of ejection holes arranged in a series of spiral rows. Liquid refrigerant introduced into the linear atomization to is ejected onto the inner wall of the Coanda evaporation chamber, covering it completely with a thin layer of liquid refrigerant. Liquid refrigerant is fed to the linear atomization device in a series of rapid pulses.

A refrigeration appliance includes a refrigeration circuit with a variable speed compressor, an evaporator, and a variable speed evaporator fan. A controller is operatively connected to the refrigeration circuit and is programmed to calculate a heat load ratio as a ratio between the difference between the ambient temperature and the set point temperature of the fresh-food compartment and the difference between the ambient temperature and the freezer compartment reference point; calculate a speed of one or both of the variable speed compressor and the variable speed evaporator fan as a function of the calculated heat load ratio; and operate one or both of the variable speed compressor and the variable speed evaporator fan at the calculated speed. A method of controlling temperature in cavities of a refrigerator is also provided.

A refrigerator includes a first cooler; a freezer compartment an inside of which is cooled by circulation of cooled air subjected to heat exchange by the first cooler; and a refrigerator compartment cooled by direct-cooling, using a cooling plate, wherein the cooled air subjected to heat exchange by the first cooler is to be supplied to the refrigerator compartment.
