Control method and system for intelligent maintenance of condenser dust accumulation, refrigerator and terminal

Abstract

The invention provides an intelligent ash deposition maintenance control method and system for a condenser, a refrigerator and a terminal. The intelligent ash deposition maintenance control method for a condenser of a refrigerator comprises the following steps: after detecting that a compressor is started up, detecting the pressure difference delta p at an air supply opening and an air discharge opening of the condenser every preset time, and detecting the ambient temperature tw of a place where the refrigerator works; determining the ash deposition amount gamma n of the condenser according to the pressure difference delta p and the ambient temperature tw; and sending the ash deposition amount gamma n to a terminal. According to the intelligent ash deposition maintenance control method for the condenser of the refrigerator, the purpose that the terminal judges whether ash deposition of the condenser is cleaned according to the ash deposition amount gamma n is achieved, so that maintenance personnel can clean ash deposition of the condenser, accordingly, the heat exchange efficiency of the condenser is improved, meanwhile, the energy consumption of the refrigerator cannot be increased, and the use satisfaction of a user to the refrigerator is improved. Furthermore, the phenomenon that corrosion of the condenser is quickened by too much ash deposition of the condenser is avoided, the service life of the condenser is prolonged, and further, the use satisfaction of the user to the refrigerator is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, in particular to a control method for intelligent maintenance of dust accumulation in condensers, a control system for intelligent maintenance of dust accumulation in condensers, a refrigerator and a terminal. Background technique [0002] The amount of dust accumulated in the external condenser of the refrigerator will affect the heat transfer performance of the condenser, and the deterioration of the heat transfer performance of the condenser will directly affect the overall performance of the refrigerator: on the one hand, it will increase the energy consumption of the refrigerator and cause the refrigeration of the refrigerator On the other hand, the accumulation of dust will also accelerate the corrosion of the condenser, affect the service life of the condenser, and seriously affect the user's satisfaction with the use of the refrigerator. [0003] Therefore, there is a need fo...
