Embodiment Construction

[0063] The inventors of the present application have 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 requires a high fan speed; 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 of the cooling fan is determined according to the current ambient humidity and ambient temperature of the refrigerator and the current rotational speed of the compressor.

[0064] According to the method for controlling the heat dissipation fan of the refrigerator compressor according to the embodiment of the present invention, the power supply voltage or the rotational speed of the heat dissipation fan can be controlled according to the curren...

Abstract

The invention provides a refrigerator and a control method used for a cooling draught fan of a refrigerator compressor. The control method comprises the step that power supply voltage of the cooling draught fan is controlled according to current environment humidity and the current environment temperature of the refrigerator and current rotary speed of the compressor. The refrigerator comprises the compressor, the cooling draught fan used for cooling the compressor and a control device which is assembled to confirm the power supply voltage of the cooling draught fan according to the current environment humidity and the current environment temperature of the refrigerator and the current rotary speed of the compressor. According to the refrigerator and the control method used for the cooling draught fan of the refrigerator compressor, controlling can be conducted on rotary speed or the power supply voltage of the cooling draught fan according to the current environment humidity and the current environment temperature of the refrigerator and the current rotary speed of the compressor, and compared with the prior art that by using the fixed rotary speed or the current environment temperature of the refrigerator and the current rotary speed of the compressor to control the power supply voltage of the cooling draught fan, cooling of the compressor is controlled more accurately.

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. ...
