Refrigerator temperature control method

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 temperature control method of a refrigerator. Background technique [0002] In order to achieve more accurate temperature control of existing refrigerators, most of them choose 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 compressor switch temperature point only depends on the set temperature of the refrigerator, and the comparison between the set temperature and the ambient temperature is ignored, so that The refrigeration efficiency is not high, and the energy saving effect is not good. [0003] When selecting traditional refrigerator temperature control methods, the ambient temperature is generally divided into several temperature sections, and different control methods are used for each temperature section, such as figure 1 As shown, the ambient temperatu...

AI Technical Summary

Problems solved by technology

[0010] 1. The cooling method of the existing refrigerator has the problem that the temperature of the storage room is greatly affected by the ambient temperature, and the temperature of the storage room fluctuates greatly;

[0011] 2. The refrigeration method of the existing refrigerator ignores the relationship between the ambient temperature and the refrigerator’s set temperature (target control temperature), resulting in too long working hours of the refrigeration system;

[0012] 3. The cooling efficiency of existing refrigerators is not high, and the energy saving effect is poor
