Problems solved by technology
[0002] At present, most of the refrigerators use fixed-frequency compressors, and the power of the fixed-frequency compressors is very large at the moment of starting up, which makes it difficult to start the compressors and affects the reliability of the refrigerators.
[0003] Moreover, since the starting power of the fixed-frequency compressor is very large, the starting torque of the compressor motor is very large, which makes the design of the compressor motor more difficult and increases the cost.
In addition, the large power consumption of the fixed-frequency compressor at the moment of start-up leads to a large reactive power loss of the fixed-frequency compressor, thereby reducing the efficiency of the fixed-frequency compressor, thereby reducing the energy-saving capacity of the refrigerator

The invention discloses a machine starting control method for a compressor for refrigeration equipment. The method comprises the following steps that when the compressor receives a machine starting instruction, the compressor is controlled to be started at a first rotating speed; until a preset time is passed, the compressor is controlled to operate at a second rotating speed, wherein the second rotating speed is lager than the first rotating speed. According to the machining starting control method for the compressor for the refrigeration equipment, compressor is started at the lower speed, then the compressor is controlled to operate at a normal speed, the starting power of the compressor can be reduced, and therefore the energy consumption of the refrigeration equipment is reduced. The invention further discloses a machine starting control device for the compressor for the refrigeration equipment and the refrigeration equipment.
Description
technical field [0001] The present invention relates to the technical field of refrigeration equipment, and in particular to a method for controlling the startup of a compressor of refrigeration equipment, a device for controlling the startup of a compressor of refrigeration equipment, and a refrigeration equipment. Background technique [0002] At present, most of the refrigerators use fixed-frequency compressors, and the power of the fixed-frequency compressors is very large at the moment of starting up, which makes it difficult to start the compressors and affects the reliability of the refrigerators. [0003] Moreover, since the starting power of the fixed-frequency compressor is very large, the starting torque of the compressor motor is very large, which makes the design of the compressor motor more difficult and increases the cost. In addition, the high power of the fixed-frequency compressor at the moment of start-up leads to a large reactive power loss of the fixed-f...
