Refrigerator control method

Abstract

The invention provides a refrigerator control method. The refrigerator control method comprises the following steps that S1, a refrigerator is powered on, and a compressor is started at the initial frequency; and S2, the real-time temperature T<n> in a refrigeration chamber is detected every sampling period t, and after the temperature in the refrigeration chamber is reduced to the preset temperature T<preset>, the operation frequency of the compressor is adjusted in real time according to the real-time temperature difference value DeltaT between the real-time temperature T<n> and the target temperature T<target> in the refrigeration chamber; T<preset>-T<target> is greater than or equal to 0.5 DEG C and less than or equal to 1 DEG C; and the compressor can be prevented from running at a high rotating speed all the time and being started and stopped frequently, the energy-saving effect is achieved, and the service life of the compressor can be prolonged.

Description

technical field [0001] The invention relates to the field of refrigeration devices, in particular to a control method for a refrigerator capable of avoiding frequent startup and shutdown of compressors. Background technique [0002] When the compressor in a conventional refrigerator is running, its running speed is constant (the running frequency of the compressor is constant), that is, when the temperature in the refrigerating room reaches the starting temperature, the compressor starts at a certain speed. When the temperature in the refrigerating room reaches the shutdown temperature, the compressor will stop, because the compressor will consume a lot of power when it starts up, and the constant speed will cause a waste of power. At the same time, the frequent start and stop of the compressor will shorten the use of the compressor. life. [0003] In order to adapt to the change of refrigerator heat load, energy saving, noise reduction, etc., some high-end refrigerators ha...

AI Technical Summary

Problems solved by technology

During the refrigeration process of existing refrigerators, the operating frequency of the compressor is adjusted according to the temperature change and / or the temperature change rate within the sampling period, so as to realize the rapid and precise control of the refrigerator temperature and optimize the refrigeration performance of the refrigerator. The time is too long, the energy consumption is large, and the problem of frequent start and stop of the compressor cannot be solved
