Abstract
Provided are a refrigerator, and a method for correcting temperature measurement errors of an infrared sensor including: verifying that the infrared sensor is running in an operating state; obtaining a measured operating-state value acquired by the infrared sensor sensing the temperature of a preset zone; obtaining a correction constant corresponding to the infrared sensor, the correction constant being obtained by means of a comparison between the value measured by the infrared sensor in a correction state and a standard temperature value; using the correction constant to correct the measured value and thus obtain a corrected temperature value. Using the method, the impact of an absolute error of the infrared sensor on temperature measurement is reduced; thus the accuracy of temperature measurement is improved, such that measured values directly reflect the actual temperature of the items inside a preset zone, and an accurate basis for control is provided for subsequent associated control.
