摘要： A photovoltaic air conditioner control method and apparatus and a photovoltaic air conditioner. The method comprises: detecting in real time the grid-connected side inverter module temperature and the grid-connected side current of a photovoltaic air conditioner; determining the interval in which the grid-connected inverter module temperature is located and the interval in which the grid-connected side current is located; and, on the basis of the determining results, performing frequency-limiting and frequency-reduction control of the photovoltaic air conditioner. By means of the present method, rapid frequency limiting and reduction can be implemented without the need to detect the operating frequency of the compressor, preventing the equipment from being damaged due to the continuous increase of the operating frequency of the compressor when the power of the photovoltaic side power generation is high, and also avoiding repeated frequency limiting and reduction of the compressor affecting the current heating or cooling effect of the photovoltaic air conditioner.

摘要： An air conditioner includes an adapter including a control unit that controls the air conditioner using a learning model and a communication unit that communicates with a server device that generates the learning model on the basis of operation history data of the air conditioner. The adapter includes an acquisition unit, a determination unit, an erasing unit, and a transmission unit. The acquisition unit acquires the data every predetermined cycle from the air conditioner. The determination unit determines whether or not an amount of change between temporally continuous data of the data acquired by the acquisition unit is within a predetermined range. The erasing unit leaves at least one of the continuous data and deletes the other data in a case where the amount of change between the continuous data is within the predetermined range. The transmission unit transmits the data after being deleted by the erasing unit to the server device. It is possible to reduce traffic of data used for learning of artificial intelligence (AI) while maintaining learning accuracy of the Al.

摘要： A motor-driven fan device includes a motor, a processor, a storage with a lookup table stored therein, and a speed detection unit. The processor queries the lookup table or calculates to acquire the target driving voltage and a corresponding target rotating speed of the motor. When the rotating speed difference is not within the range of the preset rotating speed difference, the processor repeatedly adds a gain value to the target driving voltage to acquire a new target driving voltage, acquires the actual rotating speed and the target rotating speed, and determines whether the rotating speed difference is within the range of the preset rotating speed difference. The processor maintains the operation of the motor at the target rotating speed at that point by using the constant speed control method when the absolute value of rotating speed difference is within the range of the preset rotating speed difference.
