[0075] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0076] First, the terms involved in this application are explained:

[0077] Air Conditioner: Generally, it includes cold source / heat source equipment, cold and hot medium distribution system, terminal device and other auxiliary equipment. It mainly includes refrigeration host, water pump, fan and pipeline system. The terminal device is responsible for using the cold and hot water distributed to process the air state so that the air parameters of the target environment meet certain requirements.

[0078] Internal pipe temperature: The temperature of the air conditioner indoor unit coil. This temperature depends on many factors, including indoor air temperature, humidity, cooling or heating capacity of the air conditioning system, and the working status of the indoor unit.

[0079] Frost: Air conditioning frost refers to the phenomenon of frost or freezing on the indoor or outdoor unit of the air conditioner.

[0080] The embodiments of the present application provide an air conditioning control method, device, electronic device, and computer-readable storage medium. Specifically, the embodiments of the present application provide an air conditioning control device applicable to the air conditioning control method, the air conditioning control device including an air conditioning device and a main control device of the air conditioning device, such as a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner, an embedded air conditioner, etc.

[0082] However, the existing air-conditioning control technology has low accuracy in judging the frosting condition of the air-conditioning equipment and performing defrosting. It is impossible to accurately judge whether frost has formed outside the air-conditioning equipment and the specific situation of the frost. As a result, the air-conditioning outdoor unit may frequently enter the defrost mode or turn on the defrost function after frosting. This not only makes the air-conditioning operation more power-consuming, but may also cause the indoor temperature to fluctuate, seriously affecting the comfort of the indoor environment. In addition, after the air-conditioning outdoor unit is frosted, the indoor environment cannot be quickly heated up, and a good heating effect cannot be achieved, resulting in a poor user experience.

[0083] The embodiment of the present application provides an air conditioning control method, device, electronic device and computer-readable storage medium. The method adopts the method of determining that the current change rate of the air conditioner's external fan reaches a first preset threshold, obtaining the air conditioner's external fan temperature information and the air conditioner's internal pipe temperature information; determining the temperature difference information according to the external fan temperature information, wherein the external fan temperature information at least includes: the current external fan temperature value and the historical external fan temperature value before the first preset time corresponding to the current external fan temperature value; determining the target operation strategy according to the temperature difference information, wherein the target operation strategy is the operation strategy for dealing with the frosting problem under the temperature difference information; and controlling the operation of the air conditioner according to the target operation strategy and the internal pipe temperature information.

[0084] In summary, the air conditioning control method provided in the embodiment of the present application can control the air conditioning operation according to the inner tube temperature information and the external fan temperature information when the external fan current change rate meets the conditions, so as to cope with the air conditioning frosting problem, thereby achieving the technical effect of extending the air conditioning heating operation time and avoiding the air conditioning from frequently entering the defrost mode.
