Abstract

The application relates to the technical field of household appliances, and discloses a method for controlling an air conditioner, which comprises the following steps of detecting whether refrigerant leaks or not; the method comprises the steps of obtaining the external environment temperature under the condition that the refrigerant leaks, obtaining the target operating frequency and the operating time according to the external environment temperature, and controlling the air conditioner to recover the refrigerant according to the target operating frequency and the recovery time. The target operating frequency and the operating time are obtained according to the external environment temperature, so that the target operating frequency and the operating time can be changed along with the change of the external environment temperature, and the possibility that the compressor is stopped before the refrigerant is not recovered is reduced because the external environment temperature is too high. Meanwhile, under the condition that the refrigerant leaks, the refrigerant is recovered, so that the refrigerant leakage quantity can be reduced, and the use cost of the air conditioner is reduced. The application also discloses a device for controlling the air conditioner, electronic equipment and a storage medium.

Method and device for controlling air conditioner, electronic equipment and storage medium Technical Field The present application relates to the technical field of home appliances, and for example, to a method, an apparatus, an electronic device, and a storage medium for controlling an air conditioner. Background At present, an air conditioner is used for carrying out heat transportation by means of refrigerants, the refrigerant filling amount in the air conditioner with good performance is fixed, and the performance of the air conditioner can be reduced due to too much or too little refrigerant filling amount. The pipelines in the air conditioner are welded more, and the indoor and outdoor are connected through the connecting pipe. Therefore, the refrigerant leakage is caused by poor welding or loose connection. In the existing scheme, when detecting system refrigerant leakage, the air conditioner only sends out a reminding signal, and maintenance personnel often need to find out a system leakage point for repair welding, re-pump out and fill the refrigerant when overhauling. If maintenance personnel cannot timely log in for maintenance, the refrigerant in the system can be completely leaked into the atmosphere, so that waste and environmental pollution are caused. Therefore, when detecting leakage of the refrigerant, the prior art generally controls the compressor to operate for a preset time according to a preset frequency to recover the refrigerant. In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: because the compressor may be overloaded in case of a high external environment temperature, the compressor is stopped before the refrigerant is recovered.
