A method for starting an air conditioner compressor, a storage medium, and an air conditioner

Abstract

The invention discloses a method for starting an air conditioner compressor, a storage medium and an air conditioner. The method includes: obtaining the starting frequency, target frequency and target duration of the compressor, and determining the frequency adjustment speed according to the starting frequency, target frequency and target duration , the adjustment frequency is determined according to the first operating frequency of the air-conditioning compressor at the current moment and the second operating frequency at the next moment obtained by calculating the frequency adjustment speed at each preset interval, and the adjustment frequency is adjusted according to the adjustment frequency The operating frequency is adjusted so that the operating frequency of the air conditioner compressor reaches the target frequency after the target time period. In this way, during the start-up process of the compressor, the operating frequency of the compressor can be gradually increased. On the one hand, the target frequency can be reached within the target time to achieve rapid cooling or heating. On the other hand, the compressor can be prevented from directly entering high-frequency operation. The resulting damage can prolong the life of the compressor.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for starting an air conditioner compressor, a storage medium and an air conditioner. Background technique [0002] In the existing frequency conversion air conditioning system, the outdoor unit receives the operating parameters from the indoor unit during the working process, so that the compressor of the outdoor unit can be controlled to start at a specific frequency. At present, the start-up process of the existing air-conditioning compressor is divided into two modes: low-frequency start-up and high-frequency start-up. The low-frequency starting method is to start according to the low-frequency frequency first, and the compressor enters the normal control mode after the starting is stable. Although it can ensure a stable start, it takes a long time to reach the operating frequency and cannot achieve rapid cooling or heating. The high-frequency starting metho...

Problems solved by technology

The low-frequency starting method is to start according to the low-frequency frequency first, and the compressor enters the normal control mode after the start-up is stable. Although the start-up can be guaranteed, it takes a long time to reach the operating frequency and cannot achieve rapid cooling or heating.

The high-frequency starting method is to start directly according to the high-frequency frequency. Although high-frequency operation can be quickly achieved to achieve rapid cooling or heating, the compressor is directly started at high frequency, which is likely to cause damage to the compressor and affect the service life of the compressor.
