Problems solved by technology

[0004] However, the above-mentioned 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 step failure shutdown, and, It is easy to cause the pressure of the refrigeration system to exceed the standard, thus reducing the reliability of the compressor operation

Embodiment 1

[0065] Embodiment 1, the air conditioner receives a sterilization instruction, 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 The temperature threshold T2 determines that the current environment satisfies the preset conditions, controls the air conditioner to run the sterilization mode, and sets the set temperature Ts to 50°C. In the sterilization mode, the initial speed of the indoor motor runs at the low wind speed r(0)=r_L=800rpm, the wind deflector is at the patio airflow position, the initial speed of the outdoor DC motor is R(0)=R_L=600rpm, the compressor The initial frequency is F(0)=F_low=35Hz. After the first preset time of heating operation of the air conditioner, the temperature value of the indoor heat exchanger T c = 58°C, ...

Embodiment 2

[0066] Embodiment 2, the air conditioner receives the 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 The temperature threshold T2 determines that the current environment satisfies the preset conditions, controls the air conditioner to run the sterilization mode, and sets the set temperature Ts to 50°C. In the sterilization mode, the indoor motor runs at the low wind gear speed r(0)=r_L=800rpm, and the wind deflector is at the patio airflow position. The initial speed of the outdoor DC motor is R(0)=R_L=600rpm, and the initial frequency of the compressor is F(0)=F_low=35Hz. After the first preset time of air conditioner heating operation, for example, after 2 minutes, the indoor heat exchanger coil temperature ...

Embodiment 3

[0067] Embodiment 3, the air conditioner receives a sterilization command, 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 threshold. The temperature threshold T2 determines that the current environment satisfies the preset conditions, controls the air conditioner to run the sterilization mode, and sets the set temperature Ts to 50°C. In the sterilization mode, the indoor motor runs at the low wind gear speed r(0)=r_L=800rpm, and the wind deflector is at the patio airflow position. The initial speed of the outdoor DC motor is R(0)=R_L=600rpm, and the initial frequency of the compressor is F(0)=F_low=35Hz. After the first preset time of air conditioner heating operation, the temperature of the indoor heat exchanger Tc = 50 ° C, increase t...

Abstract

The invention provides a sterilization control method and device of an air conditioner, the air conditioner and a storage medium. The method comprises the steps of after receiving a sterilization instruction, judging whether the current environment meets preset conditions or not; if yes, controlling the air conditioner to enter a sterilization mode; and in the sterilization mode, controlling an outdoor direct current motor to operate at a first preset rotating speed, controlling an indoor motor to operate at a second preset rotating speed, controlling a compressor to operate at a first preset frequency, obtaining a temperature value of an indoor heat exchanger after operation is conducted for a first preset time, and adjusting one or more of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor according to the temperature value of the indoor heat exchanger, wherein in the adjusting process, the priority of adjusting the rotating speed of the outdoor direct current motor is the highest, and the priority of adjusting the frequency of the compressor is the lowest. According to the sterilization control method and device of the air conditioner, the air conditioner and the storage medium provided by the invention, normal operation of the compressor during high-temperature sterilization of the air conditioner can be guaranteed, so that 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 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 high temperature sterilization function of air conditioners has become the focus of relevant technical personnel. The high temperature sterilization function of air conditioners is to use the high temperature of indoor heat exchangers to inactivate germs and viruses. Therefore, The high-temperature sterilization function is to control the temperature of the coil of the indoor heat exchanger to be kept above 56°C. The essence of high-temperature sterilization is heating. The severe heating condition stipulated by the national standard is the maximum operating heating condition, which is referred to as the high heating condition. That is, the indoor dry and wet bulb is 27°C / ...
