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

[0072] Embodiment 1, the air conditioner receives a self-cleaning and sterilization command, and detects that the indoor ambient temperature Tin=27°C and the outdoor ambient temperature Tout=33°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, a...

Embodiment 2

[0073] Embodiment 2, the air conditioner receives the self-cleaning and sterilization instruction, 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...

Embodiment 3

[0074] Embodiment 3, the air conditioner receives the self-cleaning and sterilization instruction, and 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 speed of the indoor motor is switched from the current speed or stop state to the low wind gear r_L=800...

Abstract

The invention provides a self-cleaning sterilization control method and device for an air conditioner, the air conditioner and a storage medium. The method comprises the steps that after a self-cleaning sterilization instruction is received, whether the current environment meets preset conditions or not is judged; if yes, the air conditioner is controlled to enter a self-cleaning mode, when the difference value between the temperature value of an outdoor heat exchanger and the outdoor environment temperature value is smaller than a preset difference value, the air conditioner is controlled to be switched to a sterilization mode, and the air conditioner is controlled to conduct heating in the sterilization mode; and an outdoor direct current motor, an indoor motor, a compressor and an electronic expansion valve are controlled to operate at the set rotating speed, frequency and opening degree, and one or more of the components are adjusted according to the temperature value of the indoor heat exchanger after operation is conducted for a first preset time. The total operation time of the self-cleaning sterilization stage can be shortened, normal operation of the compressor during high-temperature sterilization of the air conditioner can be guaranteed, and therefore the operation reliability of the compressor during high-temperature sterilization and the high-temperature sterilization reliability of the air conditioner are improved.

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...
