Problems solved by technology

[0004] However, the conventional sterilization control method only considers the improvement of the sterilization effect, and does not consider the reliability of the compressor during sterilization. When the indoor and outdoor ambient temperature is high, it is easy to trigger a drive out-of-synchronization fault shutdown, and it is easy to Cause the problem that the pressure of the refrigeration system exceeds the standard, thus reducing the reliability of the compressor operation

Embodiment 1

[0069] Embodiment 1: The air conditioner receives a self-cleaning and sterilization command, detects that the indoor ambient temperature Tin=27°C, and the outdoor ambient temperature Tout=42°C. At this time, it is considered that the indoor ambient temperature Tin is greater than the first temperature threshold T1, and the outdoor ambient temperature Tout is greater than The second temperature threshold T2 determines that the current environment meets the preset conditions, controls the air conditioner to enter the self-cleaning mode, and proceeds to the first stage, that is, the frosting stage, controls the air conditioner to cool, the indoor motor stops, and the indoor heat exchanger is in the frosting stage , when the frosting exit condition is met, enter the second stage, that is, the frosting water stage, and perform the following actions at the same time: a. The speed of the indoor motor is switched from the current speed or stop state to the low wind gear r_L=800rpm, and ...

Embodiment 2

[0070] Embodiment 2: The air conditioner receives a self-cleaning and sterilization instruction, detects that the indoor ambient temperature Tin=26°C, and the outdoor ambient temperature Tout=30°C. At this time, it is considered that the indoor ambient temperature Tin is greater than the first temperature threshold T1, and the outdoor ambient temperature Tout is greater than The second temperature threshold T2 determines that the current environment meets the preset conditions, controls the air conditioner to enter the self-cleaning mode, and proceeds to the first stage, that is, the frosting stage, controls the air conditioner to cool, the indoor motor stops, and the indoor heat exchanger is in the frosting stage , when the frosting exit condition is met, enter the second stage, that is, the frosting water stage, and perform the following actions at the same time: a. The indoor motor speed is switched from the current speed or the stop state to the low wind gear r_L=800rpm, and...

Embodiment 3

[0071] Embodiment 3: The air conditioner receives a self-cleaning and sterilization command, detects that the indoor ambient temperature Tin=25°C, and the outdoor ambient temperature Tout=25°C. At this time, it is considered that the indoor ambient temperature Tin is greater than the first temperature threshold T1, and the outdoor ambient temperature Tout is greater than The second temperature threshold T2 determines that the current environment meets the preset conditions, controls the air conditioner to enter the self-cleaning mode, and proceeds to the first stage, that is, the frosting stage, controls the air conditioner to cool, the indoor motor stops, and the indoor heat exchanger is in the frosting stage , when the frosting exit condition is satisfied, enter the second stage, that is, the frosting water stage, and perform the following actions at the same time: a. The indoor motor speed is switched from the current speed or the stop state to the low wind gear r_L=800rpm, a...

Abstract

The present invention proposes a self-cleaning and sterilization control method and device for an air conditioner, an air conditioner and a storage medium, including: after receiving a self-cleaning and sterilization instruction, judging whether the current environment meets a preset condition; if so, controlling the air conditioner to enter self-cleaning mode, and when the difference between the temperature value of the outdoor heat exchanger and the outdoor ambient temperature value is less than the preset difference value, the air conditioner is controlled to switch to the sterilization mode. In the sterilization mode, the air conditioner is controlled to heat and the outdoor AC motor is controlled. The on or off state of the indoor motor, compressor and electronic expansion valve operates at the set speed, frequency and opening degree, and after running for the first preset time, one of the above components is activated according to the temperature value of the indoor heat exchanger Or multiple adjustments. The invention can reduce the total running time of the self-cleaning and sterilization stage, and ensure the normal operation of the compressor during the high-temperature sterilization of the air conditioner, thereby improving the reliability of the operation of the compressor during the high-temperature sterilization and the reliability of the high-temperature sterilization of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner self-cleaning and sterilization control method and device, an air conditioner and a storage medium. Background technique [0002] With the health needs of users during the use of air conditioners, the self-cleaning high-temperature sterilization function of air conditioners has become the focus of relevant technical personnel. After the completion, defrosting is carried out, and the condensed water produced by the defrosting washes away the dust to realize the self-cleaning effect of the heat exchanger. After the self-cleaning is completed, high-temperature sterilization is carried out. temperature to inactivate germs and viruses. Among them, the self-cleaning stage controls the frosting of the indoor heat exchanger, which is essentially cooling, while the high-temperature sterilization stage is essentially heating, and the switching between cooling a...
