    摘要： A device (1) for detecting overicing of heat exchanger (5, 505, 605) comprising
    an inflowing pressure sensor (15, 115, 315) located on the inflow side (8) of the flowing medium (4) and measuring a pressure on the inflow side (8),
    an outflowing pressure sensor (16, 116, 316) located on the outflow side (9) of the flowing medium (4) and measuring a pressure on the outflow side (9),
    a pressure differential measuring device (11) having a first pressure input (12) communicating with the output of the inflowing pressure sensor (15, 115, 315), and
    a second pressure input (13) communicating with the output of the outflowing pressure sensor (16, 116, 316)
    a processing unit (18) calculating a pressure difference (Δp) between the outflowing pressure (P2) and the inflowing pressure (P1) and calculating an average value (Apavg) of the pressure difference, wherein the processing unit (18) is configured to transmit a defrosting signal in the case that the average value (Apavg) of the pressure difference is greater than an upper permissible value of the pressure difference (ΔpsP).

    摘要： Proposed is a refrigerator in which a width of an internal flow path of a fluid introduction part and a width of an internal flow path of a guide flow path are equal, and a front wall of the fluid introduction part is formed to incline rearward gradually downward. Accordingly, freezing of a connection portion between the fluid introduction part and the guide flow path can be prevented, and defrost water flowing down into the fluid introduction part through the guide flow path can more efficiently flow downward without becoming stagnant in an associated portion.

    摘要： A method for controlling a refrigerator according to the present invention comprises the steps of: 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 the blockage of an air channel in the heat-exchange space on the basis of the difference in value of the temperature between a first sensed temperature (Ht1), which is the lowest value, and a second sensed temperature (Ht2), which is the highest value, from among the sensed temperatures of the heating element.

    摘要： A control method of a refrigerator, according to an embodiment of the present invention, comprises the steps in which: a heating element of a sensor which is responsive to a change in the flow rate of air is turned off after being turned on for a predetermined period of time; a first sensing temperature (Ht1) of the heating element is sensed in a state in which the heating element is on, and a second sensing temperature (Ht2) of the heating element is sensed in a state in which the heating element is off; and the amount of frost on an evaporator is sensed on the basis of the temperature difference value between the first sensing temperature (Ht1) and the second sensing detection temperature (Ht2).
