Embodiment Construction

[0026] The invention discloses a refrigerator noise control method using a frequency conversion compressor. The refrigerator has an electric control device, and the electric control device of the refrigerator is an integrated circuit controlled by a single-chip microcomputer. The noise control method of the refrigerator using the frequency conversion compressor of the present invention includes a power-on control method and a running control method;

[0027] The power-on control method is: Tmp is a real number, 10°C≤Tmp°C≤43°C; the specific value of Tmp is set by the designer for different types of refrigerators.

[0028] TH°C is the ambient temperature, and Time is the running time of the low ambient temperature inverter compressor, and its unit is hour;

[0029] When TH℃≤Tmp℃, the electric control device of the refrigerator controls the variable frequency compressor to run continuously at a fixed lower frequency F0 Hz for Time hours and then shuts down, and then switches to ...

Abstract

The invention discloses a refrigerator noise control method using a frequency conversion compressor. The refrigerator has an electric control device, including a power-on control method and a running control method; When the change passes through the frequency hopping coverage area, the electronic control device adjusts the operating frequency of the variable frequency compressor to (HH+2) hertz at the frequency hopping coverage area; when the operating frequency of the variable frequency compressor changes from high to low through the frequency hopping coverage In the zone, the electronic control device adjusts the operating frequency of the variable frequency compressor to (LL-2) Hz at the frequency hopping coverage area. The control method of the present invention can not only quickly cool down the refrigerator when it is powered on for the first time, but also prevent the frequency conversion compressor from running at the resonance frequency, reduce vibration and noise, improve the service life of the vibration-receiving parts and the user experience, and maintain the frequency conversion operation. It has the advantages of energy saving and has good promotion and application value.

Description

technical field [0001] The invention relates to the technical fields of electricity and refrigeration, and relates to a refrigerator noise control technology using a variable frequency compressor. Background technique [0002] Inverter compressor refers to a compressor with constant speed (fixed frequency compressor), which can continuously adjust the speed within a certain range through a control method, and can continuously change the output energy of the compressor. It is widely used in refrigerators. [0003] Usually, when the frequency conversion refrigerator is running, the speed of the compressor is adjustable from 1200-4500RPM (frequency 20-75Hz). The compressor will vibrate when it is running, and the source of the vibration is caused by the inertial force during rotation. Refrigerators will vibrate in different degrees at different operating speeds when matching performance. The design of the connecting pipeline and the reliability of the transmission path during ...
