A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is provided with at least one air-conditioning membrane and an oxygen-rich gas collection chamber and configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter the oxygen-rich gas collection chamber. An air pump pumps gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that a ratio of the content of nitrogen in the freshness-keeping space to the content of oxygen in the freshness-keeping space is greater than 78/21.

A refrigeration appliance has a cooling chamber for receiving products to be refrigerated, the cooling chamber being delimited by a cooling chamber wall. A fan is fastened to the cooling chamber wall and is configured to deliver air through an air channel of the refrigeration appliance to the cooling chamber. A damping disc is located on a side of the fan close to the cooling chamber wall. The damping disc has a plurality of elevations which lie against the cooling chamber wall, and the damping disc has a plurality of apertures extending in a peripheral direction of the damping disc. The damping disc is configured to damp vibrations which arise during operation of the fan in order to separate the fan and the cooling chamber wall in terms of vibration.

Disclosed herein is a refrigerator having an improved configuration of an inner wall forming a storage compartment and capable of improving an appearance of the storage compartment. The refrigerator includes a main body having a storage compartment, an inner case forming an inner space of the main body, and a cover plate installed inside the inner case to form an exterior of the storage compartment and formed of a ceramic material.

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.

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 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.

A vacuum insulated refrigerator structure with a vacuum core material filled in around an elongated umbilical. The vacuum insulated refrigerator structure is made of a shell having a liner and a wrapper wherein the shell forms an internal cavity. A gas permeable casing surrounds the entire length of the elongated umbilical passing through the internal cavity of the shell. A vacuum tube is inserted at a first opening between the gas permeable casing and the elongated umbilical and a second end of the elongated umbilical is coupled to the shell at a second opening in the liner. A vacuum is formed in the internal cavity of the shell through the vacuum tube while adding the vacuum core material fill. In the shell, an elongated umbilical has one or more elongated internal passageways wherein the one or more utility lines may be routed through the one or more elongated internal passageways.

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 refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is provided with at least one air-conditioning membrane and an oxygen-rich gas collection chamber and configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter the oxygen-rich gas collection chamber. An air pump pumps gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that a ratio of the content of nitrogen in the freshness-keeping space to the content of oxygen in the freshness-keeping space is greater than 78/21.

A refrigerator appliance and method of dispensing cooling air towards a targeted cooling zone for cooling objects within a fresh-food compartment. The dispensing of cooling air may be based in part on the temperature of the object within the targeted cooling zone.
