Abstract

The invention relates to a control method of a variable-frequency refrigerator. The control method is particularly suitable for refrigerating plants like refrigerators which are relatively high in energy-saving requirement and easy to control. The refrigerator comprises a mechanical temperature controller, a variable-frequency control panel and a compressor, wherein the mechanical temperature controller is responsible for setting a refrigeration temperature in the refrigerator and outputting a corresponding switch signal according to an actual temperature in the refrigerator and the refrigeration temperature; the variable-frequency control panel is responsible for collecting the switch signal of the mechanical temperature controller, and analyzing and processing the switch signal to intelligently analyze the turn on / off time of the compressor, thereby controlling the running speed of the compressor. The control method of the variable-frequency refrigerator is simple in structure and convenient to operate, and particularly applicable to refrigeration control of the refrigerator. The variable-frequency control panel of the variable-frequency refrigerator can intelligently record the turn on / off ratio of the compressor, so that the running speed of the compressor is controlled and energy is saved.

Description

technical field

[0001] The invention relates to a control method of a frequency conversion refrigerator, and the control method is especially suitable for refrigeration devices with high energy saving requirements and simple control, such as refrigerators. Background technique

[0002] Household appliances, such as air conditioners, refrigerators, washing machines, etc., more and more use frequency conversion control to achieve the purpose of energy saving and noise reduction; traditional frequency conversion controllers include two parts: frequency conversion control module and control signal module, among them, the control signal module It is a human-computer interaction module, which can realize the control of the frequency conversion control module according to the signal input of people. After receiving the instruction of the control signal module, the frequency conversion control module adjusts the operating speed of the compressor to achieve the process of frequency co...
