Air conditioner and its control method

Abstract

The invention relates to an air conditioner and a control method thereof. The control method of the air conditioner includes: after the air conditioner is powered on for the first time and started to run, acquiring the outdoor ambient temperature where the air conditioner is located; when the outdoor ambient temperature is greater than or equal to a first preset temperature threshold , control the compressor of the air conditioner to continuously increase the frequency; when the outdoor ambient temperature is lower than the first preset temperature threshold, control the compressor to increase the frequency intermittently. The present invention controls the up-frequency mode of the compressor after startup according to the outdoor ambient temperature, avoids limiting the operating capacity of the compressor and delaying the up-frequency time of the compressor, not only can ensure the normal oil return of the compressor, but also can When it is higher, the up-frequency time of the compressor is greatly shortened, so as to achieve the purpose of rapid cooling or heating, improve the cooling or heating effect in the short period of time after the air conditioner is turned on, and improve the user experience.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner and a control method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking an air conditioner as an example, in order to meet the needs of users for rapid cooling and heating, thereby bringing a more comfortable experience, when the existing air conditioner is just turned on, the compressor is generally quickly ramped up to run at a higher frequency. When the compressor is running, the refrigerant in the compressor will be quickly discharged and circulated in the piping system. During the circulation process, the lubricating oil will be discharged from the compressor together with the refrigerant and enter the pipeline. Only when the discharged lubricating oil returns to the compressor smoothly (that is...

AI Technical Summary

Problems solved by technology

[0003] Although the above setting method ensures normal oil return, the setting method of forcing the compressor to continue to run at the oil return frequency for a period of time makes the compressor’s frequency increase time too long when the air conditioner is turned on for rapid cooling and heating, which slows down the compression. The speed at which the air conditioner reaches the maximum operating frequency also increases the time for rapid cooling and heating after the air conditioner is turned on, which in turn affects the effect of rapid cooling and heating of the air conditioner and brings a bad user experience

That is to say, the existing air conditioner start-up frequency increase control method has the problem of poor rapid cooling and heating effects due to the long time of frequency increase.
