Problems solved by technology

Noise changes in compressors and refrigeration systems due to changes in refrigeration load have not yet been solved by a good technical solution. Most of them suppress the increase in noise under high-load conditions by adding sound-absorbing and vibration-damping materials. The disadvantage is that it increases costs. The noise reduction effect is limited, especially the low-frequency noise below 1000HZ, and the sound absorption effect is poor

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In the prior art, the operating speed of the compressor of the inverter refrigerator is generally controlled comprehensively based on factors such as the ambient temperature, the set temperature, and the difference between the compartment temperature and the target temperature. When it is judged that the speed of the compressor increases, the compressor is generally adjusted immediately, that is, it runs directly according to the target speed. At this time, t...

Abstract

The invention discloses a noise control method of a variable frequency refrigerator, and relates to the technical field of refrigerators. The noise control method comprises the steps that the temperature of a condenser, the temperature of an evaporator and the current rotating speed and the target rotating speed of a compressor are monitored in real time; and when the compressor needs to be accelerated, the current rotating speed of the compressor is compared with the target rotating speed, and the speed of the compressor is controlled according to a certain control mode. According to the noise control method, the acceleration speed of the compressor is controlled by judging the temperature change trend of the condenser and the temperature change trend of the evaporator, smooth transition of noise of the whole machine can be achieved, the maximum noise is effectively reduced, and the user experience is better.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a noise control method of an inverter refrigerator. Background technique [0002] With the continuous improvement of users' requirements on the living environment, the noise level of home appliances has attracted more and more attention from consumers; as a 24-hour running electrical appliance at home, the noise level of the refrigerator has an important impact on the user experience. Due to its low-noise feature, inverter refrigerators are becoming more and more popular among users, and their market share continues to increase. The noise level of the frequency conversion refrigerator is affected by factors such as the speed of the compressor, the speed of the fan, and the cooling conditions. , the noise of the whole machine fluctuates within a certain range. [0003] When the speed of the compressor is constant, the noise of the compressor changes with the ch...
