A method of reducing moisture content of a cooling compartment includes increasing a temperature of the cooling compartment to a minimum temperature level, decreasing the temperature of the cooling compartment to a maximum temperature level, and draining any condensed moisture from the cooling compartment.

A system for reducing moisture content of a cooling compartment includes a coil assembly configured to increase a temperature of the cooling compartment to a minimum temperature level and decrease the temperature of the cooling compartment to a maximum temperature level, and a drain for draining any condensed moisture from the cooling compartment.

The present invention relates to a refrigerator controlling freshness on the basis of context awareness and artificial intelligence, a server, a portable device, and a method for controlling freshness. The refrigerator controlling freshness on the basis of context awareness, according to one embodiment of the present invention, comprises: one or more partitioned storage spaces; one or more freshness sensors for sensing the freshness in an outside area or the storage spaces; a communication unit for receiving operation instruction information from the server or the portable device, and transmitting, to the server or the portable device, freshness condition information generated by the freshness sensors; and a control unit for controlling the freshness sensors and the communication unit, and performing a freshness control operation according to operation instruction information instructing an operation that differs from pre-set operating condition information that is set for any one or more of the storage spaces.

A refrigerator contains a storage compartment, a heat exchanger chamber separate from the storage compartment, a heat exchanger which can be operated as an evaporator or as a heating unit, a fan for driving an exchange of air between the storage compartment and the heat exchanger chamber, and a control unit for controlling the operation of the heat exchanger, the fan and the heating unit. The control unit assists a drying operating mode in which the fan operates at the same time as the heating unit.

A refrigerator is disclosed. The refrigerator includes a cabinet, a freezing compartment defined in the cabinet, a door coupled to the cabinet so as to open and close the freezing compartment, and a pressure regulator mounted on the cabinet on as to allow an inside of the freezing compartment to communicate with an outside of the freezing compartment to reduce the difference in pressure when the door is opened, wherein the pressure regulator includes a connecting tube mounted at the position on the cabinet, an air introduction tube connected to the connecting tube outside of the cabinet, an opening device mounted in the air introduction tube so as to open and close an inlet of the air introduction tube, and a heater disposed around the connecting tube so as to heat the connecting tube to thus eliminate frost accumulated on the inner surface of the connecting tube.

A refrigeration apparatus has a cool chamber for receiving items to be cooled. The refrigeration apparatus has a guide arrangement for guiding movement of a moisture-absorbing sheet into and out of the cool chamber so that the moisture-absorbing sheet can absorb moisture in the cool chamber. In an example, the moisture-absorbing sheet has one or more permanent magnets for removably attaching the moisture-absorbing sheet to a wall of the cool chamber. In another embodiment, the moisture-absorbing sheet has a water-absorbing layer for absorbing moisture from the cool chamber and a water-storage layer located inwardly of the water-absorbing layer for storing water.

In an insulator including an adsorbent configured to adsorb gas, an initial adsorption performance of the remaining gas inside the insulator using the adsorbent and a long-term adsorption performance of gas introduced into the insulator from the outside are improved so that the short-term performance and the long-term performance of the insulator can be simultaneously improved. An adsorbent that is a first part of an adsorbent included in a vacuum insulator is accommodated in a first space formed with an inside surface of a container, and an adsorbent that is a second part of the adsorbent is dispersed into a second space formed with an inside surface of an outer envelope and an outside surface of the container.

A refrigerator including a moisture absorbing unit configured to absorb moisture in the cold air surrounding the evaporator. The moisture absorbing unit includes a moisture absorbing material. Therefore, undesirable frosting on the evaporator can be effectively prevented. The moisture absorbing unit can be heated by a defrosting heater disposed proximate to the evaporator and the moisture absorbing unit. Thus moisture in the moisture absorbing material can be removed and the moisture absorbing material can be repeatedly used.

A solar adiabatic cooling vest. The cooling vest utilizes adiabatic evaporation to cool hot, dry air. Hot outside humid air is drawn by an exhaust fan through an air inlet over large particles of salt to lower the air humidity before passing through a wetted wick material. Heat in the air evaporates water in the wetted wick material, thus causing the air leaving the wick material to be saturated and at a lower temperature than the incoming air. The saturated air passes through a salt filter to lower the air's relative humidity. After exiting the salt filter, the cooled, drier air passes through an air filter to further lower its humidity and remove any salt particles from the air. The cooled air is then distributed through flexible outlet cooling tubes to a person's body, room, or enclosed space.

A multilayer cover has a sandwich design for placement on a drawer of a vacuum drawer device, and the cover allows an evacuation of the drawer interior after sealing against the drawer. The cover has an outer air-tight cover layer and a core layer, recesses molded into the core layer and partly into one of the at least one outer cover layer, and an evacuation channel, a pump, and at least one sensor are arranged therein. The cover is to have a more compact design with a very low height, resulting in a minimal susceptibility to malfunction. This is achieved in that a printed circuit board is arranged on one of the at least one outer air-tight cover layers so as to face the core layer or the at least one outer air-tight cover layer is designed as a printed circuit board on which the core layer lies and on which the electric components integrated into the cover are mechanically held and are electrically connected.
