Problems solved by technology

However, because the preheating function is used in the standby state of the air conditioner, in a relatively quiet environment at night, the high-frequency electromagnetic noise generated during preheating will seriously affect the normal life of users and easily lead to user complaints

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The control method for reducing compressor preheating noise in this embodiment mainly includes the following contents, see figure 1 mentioned.

[0034] Step S1: Obtain the outdoor ambient temperature Ta, and determine the preheating time of each preheating cycle according to the outdoor ambient temperature Ta.

[0035] Each warm-up cycle includes a warm-up time and a non-warm-up time. When one preheat cycle ends, the next preheat cycle begins until the compressor begins to start normally.

[0036] Before the compressor is preheated, it is necessary to determine the preheating time of each preheating cycle according to the outdoor ambient temperature Ta, which not only ensures sufficient preheating time, ensures the preheating effect, but a...

Abstract

Provided is a control method for reducing compressor preheating noise; when a compressor is preheating, the U, V, and W windings of the compressor are electrified in a time sharing manner; two-phase windings are controlled within each period of electrification, and the electrification current of each phase winding is a wave current; each period of electrification is divided into a plurality of sub-periods; magnitudes of electrification currents within the same sub-period are controlled to be equal, and the magnitudes of electrification currents of adjacent sub-periods are controlled to be unequal; before preheating of the compressor, said control method also comprises: obtaining an outdoor ambient temperature Ta, and determining a preheating time of each preheating period according to the outdoor ambient temperature Ta.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a control method for reducing preheating noise of a compressor. Background technique [0002] Although the existing compressor preheating control method can satisfy the preheating of the compressor winding under low temperature conditions, it can ensure that the compressor can be started in time and stably when the user uses it. However, because the preheating function is used in the standby state of the air conditioner, in a relatively quiet environment at night, the high-frequency electromagnetic noise generated during preheating will seriously affect the normal life of users and easily lead to user complaints. Contents of the invention [0003] The invention provides a control method for reducing the preheating noise of a compressor, which reduces the noise during preheating. [0004] In order to solve the problems of the technologies described above, the pr...
