Air conditioner and control method thereof

Abstract

The invention relates to an air conditioner and a control method of the air conditioner. The control method of the air conditioner comprises the steps that after the air conditioner is powered on, isstarted and runs for the first time, the temperature of the outdoor environment where the air conditioner is located is acquired; when the temperature of the outdoor environment is larger than or equal to a first preset temperature threshold value, a compressor of the air conditioner is controlled to continuously conduct frequency increase operation; and when the temperature of the outdoor environment is smaller than the first preset temperature threshold value, the compressor is controlled to discontinuously conduct frequency increase operation. According to the air conditioner and the control method of the air conditioner, the frequency increase mode which is adopted after the compressor is started is controlled according to the value of the temperature of the outdoor environment, the phenomena that the operation capacity of the compressor is limited, and the frequency increase time of the compressor is prolonged are avoided, normal oil return operation of the compressor can be guaranteed, the frequency increase time of the compressor can also be substantially shortened when the outdoor temperature is high, and therefore the purpose of rapid cooling or heating is achieved, the effect of cooling or heating in a short period of time after the air conditioner is just started is improved, and the usage experience of a user is improved.

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.
