Control method and device of multi-tube air conditioner, air conditioner and storage medium

A control method of a multi-tube air conditioner comprising:

• acquiring an exhaust temperature of a compressor of the multi-tube air conditioner and an evaporation temperature of a target indoor unit of the multi-tube air conditioner, in response to detecting the multi-tube air conditioner being in a target operation state;
• determining a target opening of an electronic expansion valve of the target indoor unit according to the exhaust temperature and the evaporation temperature;
• determining an outdoor temperature of an outdoor environment where the multi-tube air conditioner is located;
• determining a minimum limited opening of the electronic expansion valve according to the outdoor temperature;
• and
• adjusting an opening of the electronic expansion valve according to the target opening and the minimum limited opening.

A multi-tube air conditioner comprising:

• a processor;
• and
• a memory storing a control program that, when executed by the processor, causes the processor to:
• acquire an exhaust temperature of a compressor of the multi-tube air conditioner and an evaporation temperature of a target indoor unit of the multi-tube air conditioner, in response to detecting the multi-tube air conditioner being in a target operation state;
• determine a target opening of an electronic expansion valve of the target indoor unit according to the exhaust temperature and the evaporation temperature;
• acquire a condensation temperature of the multi-tube air conditioner;
• determine a minimum limited opening of the electronic expansion valve according to the condensation temperature and the exhaust temperature;
• and
• adjust an opening of the electronic expansion valve according to the target opening and the minimum limited opening.
