Cooling apparatus

Abstract

The present invention relates to a cooling apparatus including a non-freezing apparatus which can stably store a liquid in a container in a supercooled state by maintaining an upper space receiving an upper portion of the container at a higher temperature than a lower space receiving a lower portion of the container. A cooling apparatus includes a cooling space, a door opening and closing the cooling space, and a non-freezing apparatus installed in the cooling space or the door, an upper space thereof being maintained in a higher temperature region than a lower space thereof. The non-freezing apparatus of the cooling apparatus includes a separation film formed between the upper space of a high temperature and the lower space of a low temperature and limiting the heat exchange between the upper space and the lower space, thereby stably maintaining the liquid in the supercooled state.

Description

TECHNICAL FIELD[0001]The present invention relates to a cooling apparatus, and, more particularly to, a cooling apparatus including a non-freezing apparatus.BACKGROUND ART[0002]Supercooling means the phenomenon that a molten object or a solid is not changed although it is cooled to a temperature below the phase transition temperature in an equilibrium state. A material has a stable state at every temperature. If the temperature is slowly changed, the constituent elements of the material can follow the temperature changes, maintaining the stable state at each temperature. However, if the temperature is suddenly changed, since the constituent elements cannot be changed to the stable state at each temperature, the constituent elements maintain a stable state of the initial temperature, or some of the constituent elements fail to be changed to a state of the final temperature.[0003]For example, when water is slowly cooled, it is not temporarily frozen at a temperature below 0° C.

AI Technical Summary

Benefits of technology

[0036]According to the cooling apparatus provided by the present invention, the temperature of the upper space of the non-freezing apparatus is maintained to be higher than that of the lower space thereof, which prevents the ice crystal formation in the upper portion of the liquid. Therefore, the liquid can be stably maintained in the supercooled state.

[0037]The non-freezing apparatus of the cooling apparatus provided by the present invention includes the separation film formed between the upper space of a high temperature and the lower space of a low temperature and limiting the heat exchange between the upper space and the lower space, thereby stably maintaining the liquid in the supercooled state. According to the cooling apparatus provided by the present invention, since the non-freezing apparatus is spaced apart from the installation surface of the cooling apparatus by a given gap, the temperature of the installation surface of the cooling apparatus less affects the non-freezing apparatus, and the cool air can be introduced and discharged through the gap. Accordingly, the food stored in the non-freezing apparatus can be cooled to the non-frozen state within a short time.

[0038]According to the cooling apparatus provided by the present invention, since the non-freezing apparatus is spaced apart from the installation surface of the cooling apparatus by a given gap, the temperature of the installation surface of the cooling apparatus less affects the non-freezing apparatus. Thus, the heating value of the heater can be reduced, and thus the energy efficiency can be improved.

[0039]The non-freezing apparatus of the cooling apparatus provided by the present invention includes the flow fan producing a forcible flow, so that the liquid contained in the container can have the utmost uniform temperature distribution.

Problems solved by technology

However, if the temperature is suddenly changed, since the constituent elements cannot be changed to the stable state at each temperature, the constituent elements maintain a stable state of the initial temperature, or some of the constituent elements fail to be changed to a state of the final temperature.

Accordingly, a complicated apparatus for producing the electric field or the magnetic field should be provided to keep the received object in the supercooled state, and the power consumption is increased during the production of the electric field or the magnetic field.

However, since the refrigerator controls the rotation number of a cool air circulation fan to adjust the temperature in the thermal insulation unit, if the temperature in the unit is reduced to a temperature below the set temperature, there is no means for raising the temperature to the set temperature within a short time.

In addition, the frozen goods cannot be thawed and stored again in the supercooled state.

The refrigerator has low stability in maintaining a non-frozen state.

However, if the temperature in the refrigerator is reduced to a temperature below a set temperature, there is no construction for raising the temperature.

Therefore, the refrigerator also has low stability in maintaining a non-frozen state.

However, when the food is stored in the supercooled state by slowing down the temperature change in the supercooling room by indirect cooling, it takes a long time for the food to reach the supercooled state.

Moreover, if the temperature in the refrigerator is reduced to a temperature below a set temperature, there is no construction for raising the temperature.

Accordingly, the refrigerator also has low stability in maintaining a non-frozen state.
