Off-peak power utilization defrosting control method and device, storage medium and refrigeration equipment

Abstract

The invention discloses an off-peak power utilization defrosting control method and device, a storage medium and refrigeration equipment. The off-peak power utilization defrosting control method comprises the following steps that the accumulative operation duration t0 of a compressor is detected; when the accumulative operation duration t0 reaches the defrosting starting duration t (c), the current time point is obtained to serve as a defrosting time point; the electricity utilization time period of the defrosting time point is judged, and a defrosting mode corresponding to power consumption is selected; and after the compressor enters the defrosting mode, the compressor is controlled to stop running, the accumulated running duration t0 is reset, the defrosting starting duration t (c) is adjusted according to the defrosting mode, the defrosting time point after the Nth time of defrosting is always in the power consumption time period of the low peak period, and N is a positive integer. The power consumption of defrosting operation in the peak power consumption period is effectively reduced, frequent defrosting operation in the peak power consumption period is avoided, the equipment is more intelligent, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of defrosting control, in particular to an electric defrosting control method, device, storage medium and refrigeration equipment for peak shifting. Background technique [0002] With the development of science and technology and the improvement of living standards, refrigerators and other equipment are widely used in different occasions. They can keep food fresh and quality, but at the same time, they are electrical appliances that consume a lot of power. For refrigerators with large-volume freezer compartments, it is not easy to ensure the temperature of the compartment and the freshness of food by adopting a cold storage solution. Therefore, it is still necessary to ensure the normal operation of the refrigerator during the peak period of electricity consumption. [0003] In order to improve the defrosting efficiency of the refrigerator, the defrosting heater is usually used to provide heat for the evapor...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the defrosting efficiency of the refrigerator, the defrosting heater is usually used to provide heat for the evaporator to defrost. When the defrosting heater is turned on, the operating power of the refrigerator is at its maximum. After defrosting, the temperature inside the refrigerator is lower than the preset temperature and needs to be started immediately. For refrigeration equipment, especially during the daytime in summer, the ambient temperature is high, and defrosting during peak power consumption will greatly increase the load on the power grid
