Problems solved by technology

[0006] First, since the process of driving the compressor when the temperature of the storage compartment of the refrigerator rises to a set temperature or higher and stopping the compressor when the temperature of the storage compartment drops to a set temperature or lower is repeated, storage The temperature of the storage room varies greatly, and thus the freshness of food stored in the storage room may be reduced
[0007] In addition, since the compressor is repeatedly driven and stopped, when the compressor is driven again, power consumption increases
[0008] In addition, when the storage compartment damper is fully opened, it is likely that cool air is excessively supplied to the storage compartment in a state where the damper is fully opened, thereby overcooling the storage compartment.

Abstract

A refrigerator is disclosed. The refrigerator includes a cabinet including a storage compartment, a cool air supply means configured to operate to supply cool air to the storage compartment, a temperature sensor configured to sense a temperature of the storage compartment, and a controller configured to control an output of the cool air supply means based on a difference between a set temperatureand a current temperature sensed by the temperature sensor and increase or decrease in temperature of the storage compartment sensed by the temperature sensor at a predetermined time interval.

Description

technical field [0001] The invention relates to a refrigerator and a control method thereof. Background technique [0002] Refrigerators are household appliances used to store food at low temperatures. Storage rooms need to be kept at a constant low temperature. In the case of current household refrigerators, the storage compartment is maintained within a range between an upper limit temperature and a lower limit temperature based on a set temperature. That is, the refrigerator is controlled using a method of performing a refrigeration cycle to cool the storage chamber when the temperature of the storage chamber rises to an upper limit temperature, and stopping the refrigeration cycle when the temperature of the storage chamber drops to a lower limit temperature. [0003] Korean Patent Laid-Open Publication No. 1997-0022182 (publication date: May 28, 1997) discloses a constant temperature control method for maintaining a storage compartment of a refrigerator at a constant ...
