Abstract

The invention discloses a temperature control method and device for an air conditioner, the air conditioner, a storage medium and a processor. The method comprises the steps of obtaining the current temperature of a heating device in the air conditioner, wherein the heating device comprises a power module, a heat sink and inductors for a PCB and a PFC, and the current temperature of the heating device is the minimum one in the temperatures of the heating device; determining whether the value of the current temperature of the heating device is equal to or higher than a first preset temperaturevalue or not; if the value of the current temperature of the heating device is equal to or higher than the value of first preset temperature, controlling a cooling fan of the air conditioner to run ata set high blow gear; and if the value of the current temperature of the heating device is lower than the value of the first preset temperature, controlling the cooling fan of the air conditioner torun at a set low blow gear. According to the control method, the power devices run within a safe work temperature range, and the power devices can be prevented from being damaged by overheating.
