Abstract

The invention provides a control method used for controlling a variable-frequency compressor. The control method comprises: step S104 of enabling the variable-frequency compressor to run at a second preset frequency; step S106 of enabling the variable-frequency compressor to stop for a third preset time length when the running time reaches to a second preset time length if the variable-frequency compressor which runs at the second preset frequency for the second preset time length is not stopped, and then turning back to the step S104, on the contrary, reducing the running frequency to a third preset frequency after the variable-frequency compressor is stopped and then started up; step S108 of enabling the variable-frequency compressor to run at the current frequency for a fourth preset time length; step S110 of turning back to the step S108 if the operation rate of the variable-frequency compressor is not greater than the preset operation rate in the forth preset time length, on the contrary, increasing the preset value of the frequency of the variable-frequency compressor, and turning back the step S108. According to the control method provided by the invention, the variable-frequency compressor can run at different frequencies and different rotating speeds, requirements on different use environment can be satisfied, and refrigeration effect and refrigeration rate are increased.

Description

technical field [0001] The present invention relates to the field of refrigeration equipment, and more specifically, to a control method for controlling a variable frequency compressor. Background technique [0002] In existing refrigerators, the fixed-frequency compressor can only operate at a fixed speed. Whether it is a high-temperature environment or a low-temperature environment, it operates at the same speed, and the cooling and energy-saving efficiency cannot be improved. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the purpose of one aspect of the present invention is to provide a control method for an inverter compressor, so that the operating frequency and rotation speed of the inverter compressor can be changed to meet the requirements of different use environments and improve the efficiency of the refrigeration system. Cooling energy efficiency...
