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 variable frequency compressor. A refrigerator is provided with an electric control device. The refrigerator noise control method comprises a power-on control method and an operation time control method. In the operation process of the refrigerator, when the operation frequency of the variable frequency compressor changes from lowto high and passes through a frequency hopping coverage area, the electric control device adjusts the operation frequency of the variable frequency compressor to be (HH + 2) hertz at the frequency hopping coverage area; when the operation frequency of the variable frequency compressor changes from high to low and passes through the frequency hopping coverage area, the electric control device adjusts the operation frequency of the variable frequency compressor to be (LL - 2) hertz at the frequency hopping coverage area. According to the control method, the refrigerator can be rapidly cooled when power is on for the first time, the variable frequency compressor can be prevented from operating at the resonant frequency, vibration and noise are reduced, the service life of a vibrated componentis prolonged, the use experience of a user is improved, the energy-saving advantage of variable frequency operation is kept, and the refrigerator noise control method has good application and popularization 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 ...
