Abstract
Disclosed are a refrigerant leakage detection method and device, an air conditioner and a storage medium. The method includes: acquiring an exhaust temperature of an air conditioner at various moments during a preset time period, in response to the exhaust temperature of the air conditioner being greater than a preset exhaust temperature and a target operating exhaust parameter of the air conditioner exceeding a preset range of the exhaust parameter of refrigerant leakage; determining an extreme value of the exhaust temperature and an exhaust moment corresponding to the extreme value of the exhaust temperature of the air conditioner based on the exhaust temperature at various moments; acquiring an exhaust period of the air conditioner based on the exhaust moment; and determining whether there is the refrigerant leakage in the air conditioner based on the exhaust period.
