Abstract

A refrigerator temperature control method comprises the following steps: (1) environment temperature T ext is obtained; (2) user setting temperature T set is obtained; (3) deviation T' between the environment temperature T ext and the setting temperature T set is figured out; (4) temperature inside in the refrigerator is revised according to the T'. In step (4), the temperature T in in the refrigerator is obtained; temperature correction parameter is set to T shift; if T in plus T shift is higher than the setting temperature T set, a refrigeration system is started to refrigerate a refrigerator body. An incasement temperature detecting device is arranged on the position of one third to one half range of the inner height of the refrigerator body so as to obtain temperature in the refrigerator body. The refrigerator comprises a refrigerating chamber, a cold select zone, and a refrigeration room. The method effectively solves the problem of inaccurate incasement temperature existed in the prior art; in particular, when the environment temperature is lower, improvement effect is obvious; on the basis of meeting accurate temperature controlling, the method can increase refrigeration efficiency of the refrigerator and reduces energy consumption.

Description

technical field

[0001] The invention belongs to the technical field of refrigeration and relates to a method for controlling the temperature of a refrigerator. Background technique

[0002] In order to achieve more precise temperature control, existing refrigerators mostly select different control methods according to different ambient temperatures. According to this method, if the ambient temperature does not change or does not change much, the temperature point of the compressor switch depends only on the set temperature of the refrigerator, while ignoring the contrast between the set temperature and the ambient temperature, so that Cause refrigeration efficiency is not high, and energy-saving effect is bad.

[0003] When choosing a traditional refrigerator temperature control method, the ambient temperature is generally divided into several temperature segments, and a different control method is used for each temperature segment, such as figure 1 As shown, the ambient t...
