摘要:
A refrigerator and a method for controlling the same are disclosed. A refrigerator includes a timer (40) for measuring an interval of one hour after power is supplied to the refrigerator, a door opening/closing sensor (50) for sensing opening and closing of a door, a storage unit (70) for storing information whether door is opened in a sector defined as one hour by the timer (40) and at least 7 sector units each having 24 consecutive sectors, and a control unit (100) for predicting a refrigerator use pattern in 24 sectors by overlapping 7 sector units, performing a normal operation mode to maintain a storage compartment at a first desired temperature in a sector in which door opening is predicted, and performing a power-saving operation mode to maintain the storage compartment at a second desired temperature higher than the first desired temperature in a sector in which door opening is not predicted.

The present invention relates to an external member for home appliances and a manufacturing method therefor. According to the present invention, through-holes for transmitting light emitted from a light source, such as a light-emitting device mounted on a rear surface, are not exposed to the outside by a film layer attached to a front surface of a metal layer when the light of the light-emitting device is turned off, such that an external member for home appliances with improved luxuriousness and aesthetic sensibility with respect to the appearance of home appliances can be implemented.

A freezing and cold storage device (1) and a defrosting control method therefor. The freezing and cold storage device (1) comprises a box body (100) and a door body (200). At least one storage chamber, an air supply passage for supplying cooling airflow to the storage chamber, a return air passage which is used for the airflow from the storage chamber to flow by, a cooling chamber (40) with an air supply opening portion and an air return opening portion and accommodating an evaporator (41), a fan (42) and a defrosting heater (43) and a defrosting air return passage (60) communicating the air supply opening portion and the air return opening portion of the cooling chamber (40) are defined in the box body (100). The air supply passage and the defrosting air return passage (60) are separately internally provided with an air supply valve and a defrosting air return valve (61) so as to selectively switch on and/or block the air supply passage and the defrosting air return passage (60). The defrosting control method comprises the steps of receiving a defrosting signal, starting a defrosting heater (43) disposed on an evaporator (41), closing an air supply valve, and opening a defrosting air return valve (61) so as to enable heat generated by the defrosting to circularly defrost the evaporator (41).
摘要:
In the context of a refrigeration unit having a storage chamber (1) and an evaporator (4) that cools the storage chamber (1), a processing unit (8) is set up, at a given temperature (T) of the storage chamber (1), to assign values of the air humidity (r) in the storage chamber (1) and an evaporation temperature (TD) of the evaporator (4) to one another with the assumption that the absolute water vapor content of the air of the storage chamber (1) is the same as that of water-vapor-saturated air at the evaporation temperature (TD). This assignation makes it possible on one hand to estimate the relative air humidity in the storage chamber (1) on the basis of the temperatures, and on the other hand to control the air output temperature (TD), at constant temperature (T) in the storage chamber (1), in order to influence the air humidity (r) therein.

摘要:
A refrigeration controller within a retail refrigeration cabinet controls the temperature (502) so that it approaches the maximum allowable temperature by using the most efficient fan speed for loading and time of day (507) but is varied by customer presence (505) to adhere to an algorithm reducing the noise (506) created by such machines while still creating sufficient cooling to remain within the maximum temperature while providing acceptable power economy.
摘要:
Systems and method for operating and monitoring refrigerators are described. Temperature cycles within the compartment are characterized using statistical, frequency and pattern analysis techniques to derive a steady-state characteristic of temperature within the compartment. A thermal sensor inside the conditioned area is monitored and temperature data sets can be analyzed to determine performance in comparison to a baseline, and energy consumption. Analysis of continuous temperature readings taken from individual or groups of freezers identifies patterns of variations in temperature cycles from which feedback on efficiency can be inferred. Electrical load can be determined by measuring or estimating current usage and identifying periods of time when compressors are active in the refrigerator.
