Abstract

The invention provides an air conditioner control method, an air conditioner control device, a storage medium and an air conditioner. The method comprises the following steps of judging whether the outdoor ambient temperature is greater than or equal to a set ambient temperature judgment value after a compressor of the air conditioner is started; and if the outdoor ambient temperature is judged tobe greater than or equal to the set ambient temperature judgment value, determining whether to control the compressor to stop or not according to whether the power supply voltage of the compressor isgreater than or equal to the set voltage or not so as to perform temperature protection on an Intelligent Power Module (IPM) of the air conditioner. The scheme provided by the invention can avoid theproblem of damage to the IPM of the air conditioner compressor under the condition of high ambient temperature and high voltage power supply.

Description

technical field

[0001] The invention relates to the field of control, in particular to an air conditioner control method, device, storage medium and air conditioner. Background technique

[0002] The IPM (Intelligent Power Module) module will generate heat during the use of the inverter air conditioner, and the heat will cause the temperature of the IPM module to rise. When the temperature rises to a certain value, it will damage the internal components of the IPM module. Module temperature protection measures, when the module temperature rises to the corresponding range, the compressor will be limited and the frequency will be reduced, and the compressor will be stopped to prevent the module from being damaged.

[0003] The new energy inverter air conditioner also uses the IPM power module, but the power supply voltage of the new energy air conditioner is DC power supply, and the power supply voltage range is very large. When the IPM module provides the same compressor freq...
