The invention discloses a controlling method and device of recovering of a refrigerant, a storage medium and an air conditioner. The method comprises the following steps that whether communication between an outdoor unit of the air conditioner and all indoor units is abnormal or not is determined; if the communication between the outdoor unit and at least one of the indoor units is abnormal, the outdoor unit is controlled to judge whether the outdoor unit reaches a preset automatic recovery refrigerant condition or not; if the outdoor unit reaches the automatic recovery refrigerant condition,the outdoor unit is controlled to automatically enter a preset recovery refrigerant mode, and the refrigerant of at least one indoor unit side which is in abnormal communication between all the indoorunits and the outdoor unit is recycled to the outdoor unit side. According to the scheme, the problem that the reliability is poor when the indoor units are damaged or the indoor units and the outdoor unit are in communication faults, the refrigerant cannot be recycled can be solved, and the effect of improving the reliability is achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method, device, storage medium and air conditioner for recovering refrigerant, in particular to a control method, device, storage medium and air conditioner for multi-connected air conditioners to recover refrigerant. Background technique [0002] In the air conditioner (that is, air conditioner) refrigerant recovery mode, the refrigerant can be recovered to the indoor unit or the outdoor unit by setting a recovery command for the refrigerant, and then determining that the refrigerant needs to be recovered to the outdoor unit or the indoor unit according to the recovery command. However, this recovery method requires the signal of the internal unit to recover the refrigerant. When the internal unit is damaged or the communication between the internal unit and the external unit fails, the internal unit cannot send a signal to set the refrigerant recov...
