Embodiment Construction

[0051] The inventors of the present application found that the ambient humidity has a certain influence on the heat dissipation rate. The inventors of the present application have further found that when the humidity is high, the heat dissipation rate is slow and a higher fan speed is required; when the humidity is low, the heat dissipation rate is faster and a lower fan speed is required. Therefore, in the method for controlling the cooling fan of the refrigerator compressor according to the present invention, the power supply voltage U of the cooling fan is determined according to the ambient humidity RH of the refrigerator, the ambient temperature T and the rotational speed N of the compressor. Specifically, the first voltage u1 is determined according to the ambient humidity RH and the ambient temperature T of the refrigerator; the second voltage u2 is determined according to the ambient temperature T and the rotational speed N of the compressor; the magnitudes of the first...

Abstract

The invention provides a refrigerator and a control method for a cooling fan for a refrigerator compressor. The control method for the cooling fan for the refrigerator compressor includes the steps that the first voltage is determined according to the environment humidity and the environment temperature of the refrigerator; the second voltage is determined according to the environment temperature and the rotating speed of the compressor; the first voltage is compared with the second voltage, if the first voltage is larger than the second voltage, power is supplied to the cooling fan according to the first voltage, and otherwise, power is supplied to the cooling fan according to the second voltage. Due to the fact that the influences of the environment humidity and the environment temperature of the refrigerator and the rotating speed of the compressor on the cooling effect of the compressor are considered simultaneously, the compressor is better cooled and can be protected; and meanwhile, the energy-saving effect is achieved and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator and a control method for a cooling fan used in a refrigerator compressor. Background technique [0002] There are currently two ways to dissipate heat from refrigerator compressors: radiation heat dissipation and convection heat dissipation. Radiation heat dissipation transfers heat to the surrounding air through the surface of the compressor in the form of heat radiation, and the heat dissipation rate is small and the efficiency is low; convection heat dissipation mainly transfers the heat of the compressor through the heat dissipation fan in the form of gas flow, which is mainly affected by the wind speed , depends on the cooling fan speed. The rotating speed of the heat dissipation fan of the existing refrigerator is generally fixed. Therefore, in order to meet any working conditions, the heat dissipation fan must always work at a relatively high speed. ...
