Control method of refrigeration equipment with inverter compressor

Abstract

The invention provides a control method of refrigeration equipment with an inverter compressor. The control method comprises the following steps that when the refrigeration equipment is electrified, self checking is performed; if the self checking is passed, a noise reduction mode is started to control the inverter compressor to operate at a first preset rotating speed, and whether a rapid cooling mode or rapid freezing mode request signal is received or not is detected; if the rapid cooling mode or rapid freezing mode request signal is received, the refrigeration equipment is controlled to operate in a rapid cooling mode or rapid freezing mode, and the rotating speed of the inverter compressor is increased; after the refrigeration equipment refrigerates in the rapid cooling mode or rapid freezing mode, the refrigeration equipment enters a normal operating mode, wherein when the inverter compressor operates at the first preset rotating speed, noise generated by the inverter compressor is less than a preset value. By using the control method of the embodiment of the invention, the refrigerating efficiency of the refrigeration equipment can be guaranteed, the noise of the inverter compressor can be effectively reduced, customer complaints are avoided, and the market competitiveness of the refrigeration equipment (such as refrigerators) is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a control method for refrigeration equipment with a variable frequency compressor. Background technique [0002] At present, more and more frequency conversion compressors are used in the field of refrigeration, and frequency conversion compressors have many advantages in terms of performance and energy consumption. However, the frequency conversion compressor usually has a higher power and a faster rotation speed when it is started, resulting in a higher overall noise value of the refrigeration product, resulting in more customer complaints. [0003] The disadvantage of the existing frequency conversion compressor is: when the frequency conversion compressor is working, especially when starting, due to the large temperature difference, the noise of the frequency conversion compressor is relatively large. This is because the frequency conversion compressor will ad...

However, the frequency conversion compressor usually has a large power and a fast speed when starting up, resulting in a large overall noise value of the refrigeration product, resulting in more customer complaints

[0003] The disadvantage of the existing frequency conversion compressor is: when the frequency conversion compressor is working, especially when starting, due to the large temperature difference, the noise of the frequency conversion compressor is relatively large. This is because the frequency conversion compressor will adjust the internal speed frequency according to the ambient temperature , when the speed is fast, the noise is large
