Problems solved by technology

Due to the increased noise of compressors and refrigeration systems caused by the increase of refrigeration load, there is no good technical solution in the existing technology. Most of them suppress the increase of noise under high load conditions by adding sound-absorbing and vibration-damping materials. But the disadvantage is that it increases the cost and the noise reduction effect is limited

Abstract

The invention discloses a noise control method of a frequency conversion refrigerator, and relates to the technical field of refrigerators. The invention includes: monitoring the ambient temperature, the temperature of the condenser and the current speed and target speed of the compressor in real time; when the compressor needs to increase the speed, the current speed of the compressor is compared with the target speed, and the speed of the compressor is compared. logic control. The invention can effectively reduce the noise caused by the increase of the load by optimizing the rotation speed of the compressor, improve the user experience effect, and has high market application value.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a noise control method of a frequency conversion refrigerator. Background technique [0002] With the continuous improvement of users' requirements for the living environment, the noise level of household appliances has attracted more and more attention from consumers. Inverter refrigerators are popular with users due to their low noise characteristics, and their market share continues to increase; the noise of inverter refrigerators is affected by factors such as compressor speed and refrigeration conditions. The noise of inverter refrigerators generally decreases with the decrease of compressor speed. decrease, but the noise also increases with the increase of speed; under the condition of constant compressor speed, the noise changes with the change of refrigeration conditions. The greater the load (high condensing temperature, high evaporating temperature), ...
