Problems solved by technology

However, when the heat dissipation of the condenser is small, the condensing fan is still running at high speed and cannot automatically reduce the speed, which is not conducive to energy saving and noise reduction

Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] When the refrigerator is working, it is necessary to keep the temperature inside the refrigerator within the set range. When the external ambient temperature rises, the working intensity of the refrigeration system of the refrigerator increases, and the speed of the compressor increases, and the heat emitted by the condenser increases; When the amount of high-temperature food in the refrigerator increases, the working intensity of the refrigeration system of the refrigerator increases, and the speed of the compressor increases, and the heat emitted by the condenser increases. The speed regulating control system of the condensing fan of the refrigerator of the present invention can adjust the rotating speed of the condensing fan according to the amount of heat emitted by the condenser, thereby achieving the effects of reducing noise and e...

Abstract

The invention discloses a refrigerator and a speed control system and method of a condenser fan of the refrigerator. The speed control system of the condenser fan comprises a controller, a compressor rotational speed detection circuit, temperature sensors inside and outside the refrigerator and a condenser fan rotational speed control circuit, wherein the rotational speed of a compressor is detected by the controller through the compressor rotational speed detection circuit, and the temperature inside the refrigerator and the ambient temperature are acquired by the temperature sensors; and the rotational speed of a condenser fan is controlled by the condenser fan rotational speed control circuit. The controller provided by the invention can control the rotational speed of the condenser fan according to the ambient temperature, the temperature inside the refrigerator and the rotational speed of the compressor, accordingly, when more heat is dissipated in a condenser, the rotational speed of the condenser fan is improved to meet the heat dissipation need; and when less heat is dissipated in the condenser, the rotational speed of the condenser fan is reduced to meet the heat dissipation need, and reduce energy consumption and noise.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a speed regulation control system capable of adjusting the rotating speed of a condensing fan and a refrigerator using the system. Background technique [0002] A compressor and a condenser of a refrigeration system are arranged in the mechanical room of the refrigerator. When the refrigerator is working, the heat emitted by its condenser has a great relationship with the ambient temperature, the internal temperature of the refrigerator and the speed of the compressor. The higher the ambient temperature and the internal temperature of the refrigerator, the faster the speed of the compressor, and the more heat dissipated by the condenser per unit time, and vice versa. The rotational speed of the condensing fan of the existing refrigerator is generally fixed, therefore, in order to meet any working conditions, the condensing fan must always work at a relatively high rotation...
