Method for judging filth blockage of air conditioner, air conditioner and cloud platform

Abstract

The invention discloses a method for judging filth blockage of an air conditioner, the air conditioner and a cloud platform. The air conditioner comprises a controller, and further comprises a power collection module, a rotating speed collection module, a fan and a first communication module which are connected with the controller; the controller is configured with a power drop rate limit value or a standard power curve; the power drop rate limit value or the standard power curve is sent to external equipment through the first communication module; the controller controls the fan to operate at variable rotating speed, and a power acquisition module and a rotating speed acquisition module respectively acquire the power and the rotating speed of the fan, transmit the power and the rotating speed to the external equipment and receive filth blockage signals; the cloud platform comprises a processing module, and further comprises a second communication module and a storage module which are connected with the processing module; the storage module is provided with a plurality of storage units and is used for storing data of a plurality of air conditioners; the cloud platform receives the power drop rate limit value or the standard power curve, each rotating speed and the corresponding power and stores the the power drop rate limit value or the standard power curve, each rotating speed and the corresponding power in the corresponding storage units; the processing module obtains an environment power curve and an operation power curve according to each rotating speed and the corresponding power, and judges whether filth blockage occurs or not; and when filth blockage occurs, the filth blockage signals are sent. Judgment is more accurate.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for judging whether an air conditioner is dirty and blocked, an air conditioner and a cloud platform. Background technique [0002] Existing air conditioners are provided with a dirty blocking judging device and a cleaning device for controlling whether to clean according to the judging result. However, the judgment of dirty blockage is only compared with simple parameters such as power, wind speed or outlet temperature, and the control accuracy is poor. [0003] When it needs to be cleaned but not cleaned, the heat exchange efficiency of the indoor heat exchanger will be low, the cooling and heating effect will be deteriorated, and energy consumption will be increased; when cleaning is not required, energy will be wasted. Contents of the invention [0004] In order to solve the problem of inaccurate judgment of air conditioner dirty blockage in the prior art...
