Control method of refrigerator, control device of refrigerator and refrigerator

Abstract

The invention provides a control method of a refrigerator, a control device of the refrigerator, and the refrigerator. The method comprises the following steps: detecting the current indoor temperature; judging whether the temperature variation between the current indoor temperature and the preset indoor temperature is greater than or equal to the preset indoor temperature variation or not, if so, adjusting the current running frequency of a compressor of the refrigerator, and / or the current first rotating speed of an outdoor fan of the refrigerator and / or the current second rotating speed of an indoor fan of the refrigerator; otherwise, controlling the compressor to keep the current running frequency, and / or controlling the outdoor fan to keep the current first rotating speed and / or the indoor fan to keep the current second rotating speed. Through the technical scheme provided by the invention, the working states can be adjusted by the refrigerator according to environmental temperatures and other constantly changing situations, and the refrigerator can work under the optimum condition at any time, so that the refrigerating efficiency of the refrigerator is improved, the noise of the refrigerator is reduced, and the life of the refrigerator is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a refrigerator control method, a refrigerator control device and a refrigerator. Background technique [0002] The refrigeration principle of conventional air-cooled refrigerators is as follows: the compressor drives the refrigerant to circulate in the refrigeration system (pipeline), and the high-temperature and high-pressure refrigerant in the condenser pipe dissipates heat to the ambient air through the cooling fan; the low-temperature and low-pressure refrigeration in the evaporator pipe The cooling agent is driven by the fan to circulate the air in the box, so as to realize the delivery of cooling capacity to the refrigerator room and maintain the required storage temperature of the food in the box. [0003] In order to adapt to changes in the heat load of refrigerators, save energy and reduce noise, some high-end refrigerators, especially air-cooled products, have ...

AI Technical Summary

Problems solved by technology

However, the design and operation control of the existing refrigerator refrigeration system cannot guarantee that the refrigerator will work in its optimum condition. On the contrary, as the ambient temperature changes, or the food in the refrigerator increases or decreases, the operating condition of the refrigerator will always change. Deviate from the best working condition due to changes, resulting in reduced refrigeration efficiency, increased noise, and shortened compressor life
