Problems solved by technology

[0002] The compressor speed of the existing frequency conversion refrigerator is adjusted by the temperature sensors in the refrigerator and freezer. The biggest problem with this control method is that the refrigerator adjusts the frequency of the compressor according to the temperature fluctuation reflected by the load in the box. The accuracy is poor and there is room for adjustment. Small, and can only be used on electronic temperature-controlled refrigerators, so the compressor speed changes less, and the refrigerator consumes more energy

Abstract

The invention discloses a control device of a frequency convertible refrigerator and a control method thereof. The control device comprises a frequency conversion control panel (3) and an intelligent control panel (2) connected with the frequency conversion control panel (3), wherein, the input end of the intelligent control panel (2) is connected with a temperature sensor (1), and the output end thereof is connected with the input end of the frequency conversion control panel (3); the control device is added with the intelligent control panel (2), so as to add the environmental temperature and the accumulated running time of a compressor into the running control of the refrigerator; according to the temperature of a refrigerating room and a cold preserving room, the cooling rate, the environmental temperature and the accumulated running time of the compressor, the control device of the refrigerator can control the running frequency of the frequency conversion compressor in real time to avoid the compressor from being started and stopped frequently, and the service life of the compressor can be prolonged. The invention improves the refrigerating efficiency of the refrigerator at utmost, and has the advantages of rapid temperature reduction, little energy consumption and easy energy conservation. By adopting the frequency convertible refrigerator, the effects of food cold preserving and fresh-keeping are good.

Description

technical field [0001] The invention relates to the technical field of refrigerators in household appliances, in particular to a control device and a control method for frequency conversion refrigerators. Background technique [0002] The compressor speed of the existing inverter refrigerator is adjusted by the temperature sensors in the refrigerator and freezer. The biggest problem with this control method is that the refrigerator adjusts the frequency of the compressor according to the temperature fluctuation reflected by the load in the box. The accuracy is poor and there is room for adjustment. Small, and can only be used in electronic temperature-controlled refrigerators, so the compressor speed changes less, and the refrigerator consumes more energy. Contents of the invention [0003] The present invention overcomes the shortcomings of the prior art, and provides a control device and a control method for a variable frequency refrigerator. When the control device of t...
