Embodiment Construction

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] like figure 1 Shown is a structural diagram of a refrigeration device, which includes a compressor 100 and a fan 200 arranged on a heat exchange device (not shown in the figure).

[0023] like figure 2 As shown, it is a working flow chart of the fan control method of the refrigeration equipment in a preferred embodiment. The fan control method of the refrigeration equipment is used to control the speed of the fan to avoid the compressor 100 operating at a certain frequency and the fan at a certain speed. 200 generates resonance, and the fan control method...

Abstract

The invention is applied to the field of the automatic control of refrigeration equipment and provides a method for controlling a blower of the refrigeration equipment. The method comprises the following steps: acquiring current operation frequency F to be regulated of a compressor; acquiring target rotating speed L to be regulated of the blower; judging whether the blower can be subjected to resonance with the compressor or not at the target rotating speed L to be regulated according to the current operation frequency F to be regulated of the compressor, and changing the target rotating speed L of the blower if the blower can be subjected to resonance with the compressor at the target rotating speed L to be regulated, so as to avoid the resonance with the compressor. According to the method, whether the acquired target rotating speed L is in a target rotating speed range Ln of the blower or not is judged according to the Ln which can be subjected to resonance with the compressor operating at the current operation frequency F, and the target rotating speed L of the blower is changed to avoid resonance if the acquired target rotating speed L is the Ln of the blower, so that the problem that an air conditioner emits low-frequency pulsating abnormal sound due to the resonance of the refrigeration equipment is solved, and the user comfort is improved.

Description

technical field [0001] The invention belongs to the field of automatic control of refrigeration equipment, and in particular relates to a fan control method and system of refrigeration equipment. Background technique [0002] With the development of the economy and the continuous improvement of people's quality of life, there are higher requirements for the comfort performance of refrigeration equipment. The most important aspect involved is noise, and the optimization of noise has always been the top priority of refrigeration equipment design. [0003] Nowadays, refrigeration equipment is becoming more and more complex and refined, which not only requires lower and lower noise amplitudes, but also pays more attention to the user's sense of hearing, which is the so-called no abnormal sound. The noise of general refrigeration equipment is mainly generated by compressors, indoor and outdoor fans, and air duct systems. The noise improvement work is basically carried out for com...
