The present invention relates to a refrigerator which can display a supercooled state or the proceeding degree of the supercooled state. The refrigerator includes a control apparatus which is formed in a storing space in which the cooling is performed, has a storing space composed of an upper space and a lower space between which the air or heat exchange is limited, stores a stored object in the storing space in a supercooled state, and controls the temperature of the upper space and the lower space, respectively. The refrigerator includes: a determination means determining the supercooled state of the stored object or the proceeding degree of the supercooled state; and a display means visually or aurally displaying the supercooled state or the proceeding degree of the supercooled state determined by the determination means.

The present invention relates to a supercooling apparatus which maintains an object and liquid in a supercooled state. According to the present invention, a supercooling apparatus includes a cooling chamber supplied with cool air, and a heating device (100) for preventing freezing of water by heating air over a container (200) storing an object or liquid and cooled in the cooling chamber. In this configuration, the air over the container (200) where ice crystals are easily formed is heated to prevent freezing of water stored in the container (200) and store water in a supercooled state.

The present invention discloses an apparatus for supercooling which can stably maintain a liquid in a supercooled state at below a phase transition temperature. The apparatus for supercooling, which can maintain a supercooled state of a liquid or contents even below a phase transition temperature, comprises: a storage space for storing a container accommodating a liquid or contents containing the liquid; a cooling means for cooling the liquid or contents or the storage space below the phase transition temperature of the liquid or the contents; and a temperature maintaining unit for applying energy to the surface of the liquid or contents or to a gas near the surface, wherein the liquid or the contents are maintained in a supercooled state by preventing freezing nuclei from being formed on the surface of the liquid or contents or in the gas near the surface by application of energy.

The present invention relates to a control method of a refrigerator which operates a cooling cycle including two storage compartments, a compressor, a condenser, a valve, fans, and evaporators for cooling the respective storage compartments, with one of the fans (5) corresponding to the storage compartment for storing items at relatively low temperatures being activated for a set amount of time even after the compressor is deactivated at the completion of cooling of the storage compartment for storing items at relatively low temperatures. In a refrigerator comprising a first storage compartment for storing an item, a second storage compartment for storing an item at a lower temperature than the first storage compartment, a cooling cycle including a compressor, a condenser for condensing a refrigerant from the compressor, a valve for directing the refrigerant from the condenser to first and second evaporators, with the first and second evaporators evaporating supplied refrigerants to cool the first and second storage compartments, respectively, and first and second (5) fans for circulating cool air from the first and second evaporators, respectively, and a controller for controlling the first and second (5) fans, the valve and the compressor, a control method of the refrigerator comprising: a first step of the controller activating the compressor if cooling of the second storage compartment is required and activating the second fan (5); and a second step of the controller deactivating the operation of the compressor, if the cooling of the second storage compartment is completed, and deactivating the operation of the second fan (5) after the operation of the compressor is deactivated.

The present invention relates to a cooling apparatus including a non-freezing apparatus which can be installed in a refrigerating chamber or a refrigerating chamber door and stably store food in a non-frozen state. A cooling apparatus includes a freezing chamber, a refrigerating chamber, a freezing chamber door, a refrigerating chamber door, and a non-freezing apparatus installed in the refrigerating chamber or the refrigerating chamber door and storing food in a non-frozen state. In the non-freezing apparatus, since a lower space is cooled by the cool air introduced from the freezing chamber and an upper space is cooled by the atmosphere of the refrigerating chamber, it is possible to reduce a heating value of a heater which is operated to maintain the temperature of the upper space to be higher than that of the lower space.

The present invention discloses a ultra-hydrophilic and antibacterial thin film coated metal product, and its manufacturing method. In order to easily produce an air conditioning metal material having excellent hydrophilic performance, aging property, corrosion resistance and antibacterial property on an industrial production scale without a special preprocess or postprocess, an anticorrosive thin film is selectively formed on both surfaces of a metal substrate sheet, and an ultra-hydrophilic and antibacterial Ti—(Ag, Cu and/or Co)—O—C group compound thin film is coated on both surfaces of the metal substrate sheet on which the anticorrosive thin film has been or not been formed. The metal substrate sheet is mechanically processed into a target shape.
