Abstract: There is disclosed a controlling method for a refrigerator comprising: a first defrosting step of performing defrosting for an evaporator, the first defrosting step which ends when the temperature of the evaporator reaches a first temperature; a pressure difference sensing step of measuring a difference between the pressure in a first through-hole arranged between an inlet hole for drawing air from a storage compartment and the evaporator and the pressure in a second through-hole arranged between an outlet hole for discharging air towards the storage compartment and the evaporator by using one differential pressure sensor; and a second defrosting step of performing additional defrosting for the evaporator when the measured pressure difference is a preset pressure or more.

Abstract: A refrigerator having an air pressure controllable storage container is allowed to control air pressure of the storage container to be temporarily lower than initial air pressure by turning on and off a vacuum pump. The vacuum pump sucks internal air of the storage container, and a controller turns on the vacuum pump such that internal air pressure of the storage container is lower than the initial air pressure, and turns off the vacuum pump such that the internal air pressure is restored to the initial air pressure.

Abstract: The present disclosure relates to a refrigerator having an air pressure adjusting apparatus for a storage container, and more particularly, a refrigerator having an air pressure adjusting apparatus for a storage container, capable of uniformly maintaining internal air pressure of the storage container by increasing the internal air pressure by way of an introduction of external air when the internal air pressure is excessively lowered and also preventing damages of the storage container. The refrigerator includes a storage container having an inner accommodating space and installed to be drawn out of and inserted into the refrigerator, and an air pressure adjusting apparatus to allow external air to be introduced into the storage container based on internal air pressure of the storage container, so as to increase the internal air pressure.

Abstract: A method for controlling a refrigerator includes operating, for a set duration, a heating element of a sensor which responds to changes in air flow; sensing the temperature of the heating element in on or off state; and sensing residual frost on an evaporator on the basis of the difference in value of the temperature between a first sensed temperature, which is the lowest value, and a second sensed temperature, which is the highest value, from among the sensed temperatures of the heating element.

Abstract: The present disclosure relates to a refrigerator. The refrigerator according to an embodiment of the present disclosure comprises: an evaporator; a defrost heater; a temperature sensor to sense ambient temperature around the evaporator; and a controller to control the defrost heater, wherein the controller is configured to: perform a defrost operation mode in a case of reaching a defrosting operation start time point; perform, based on the defrost operation mode, a continuous operation mode in which the defrost heater is continuously turned on, and a pulse operation mode in which the defrost heater is repeatedly turned on and off; and perform the continuous operation mode again after performing the pulse operation mode. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.
