Refrigerator

摘要

A refrigerator controls the temperature of an upper space and a lower space. A heat source supplier provides heat in the upper space. A control unit controls the heat source supplier based on the sensed temperature from a temperature sensor to maintain the temperature of the upper space to be higher than the temperature of the lower space, and control a cooling circuit to maintain the temperature of the lower space to be below the temperature of a maximum ice crystal formation zone of water and the temperature of the upper space to be over the temperature of the maximum ice crystal formation zone of water, thus maintaining a supercooled state of a stored liquid in the container as a preset state during a first time period.

主权项

1. A refrigerator, the refrigerator comprising:
a storage casing enclosing a storing space to store a container, the storing space composed of an upper space, a lower space and a separation film located between the upper space and the lower space, the separation film separating upper and lower portions of the container and including a hole through which at least a portion of the container to be stored can pass, the air or heat exchange being limited between the upper space and the lower space; a cooling circuit having a compressor and an evaporator; a temperature sensor sensing a temperature of at least one of the upper space and the lower space; a heat source supplier supplying heat to the upper space or generating heat in the upper space; and a control unit configured to: control the heat source supplier based on the sensed temperature from the temperature sensor to maintain the temperature of the upper space to be higher than the temperature of the lower space, and control the cooling circuit to maintain the temperature of the lower space to be below the temperature of a maximum ice crystal formation zone of water and the temperature of the upper space to be over the temperature of the maximum ice crystal formation zone of water, thus maintaining a supercooled state of a stored liquid in the container as a preset state during a first time period.
