The system overcomes the defects of a relatively slow communication rate and not being applicable to large data transmission which are caused by using a strong electric current loop for communication; and realizes weak-current communication between indoor and outdoor units, thereby increasing the communication rate, reducing the design cost, and solving the problem whereby an outdoor unit cannot automatically power off to lower the standby power during the process of weak-current communication.

The compressor winding iron loss heating method comprises: inputting a pulse signal into an inverter connected to a compressor, so as to control windings of any two phases among electric-motor windings of the compressor to be heated; collecting a direct-current bus voltage and an instantaneous current, and on the basis of the direct-current bus voltage and the instantaneous current, determining the actual heating power of the electric-motor windings; and performing pulse width modulation on the pulse signal on the basis of the difference between a given heating power and the actual heating power, such that the actual heating power tracks the given heating power. The compressor winding iron loss heating method abandons the way of obtaining heating data of a compressor by means of experiments, and realizes closed-loop control over the heating power of the compressor, thereby improving the stability of the heating power, without being affected by external factors such as the fluctuation of a direct-current bus voltage and differences in rotor positions.

Abstract

A control method for an air conditioner, the air conditioner comprising an air conditioner indoor unit, and the air conditioner indoor unit comprising a housing. The housing is provided with a heat exchange air outlet (11), a first air outlet (21), a first indoor air inlet (12) and a second indoor air inlet (23), the first air outlet (21) being located at a side of the heat exchange air outlet (11). The control method for the air conditioner comprises: when fresh air is introduced, causing the first air outlet (21) and the heat exchange air outlet (11) to operate at the same time. According to the control method for the air conditioner, when fresh air is introduced, especially when the difference between the outdoor fresh air temperature and the indoor ambient temperature is relatively large, fresh air being directly blown on the body of a user would make the user uncomfortable. Causing the first air outlet (21) and the heat exchange air outlet (11) to operate at the same time enables indoor air blown out by the first air outlet (21) and heat exchange air blown out by the heat exchange air outlet (11) to be mixed with the fresh air, so that the fresh air temperature is closer to the indoor ambient temperature. In particular, when the fresh air temperature is relatively low, this makes the fresh air less cold, thereby improving the comfort of the air conditioner.

Abstract

The present application relates to the technical field of smart devices, and discloses a method for controlling a smart device. The method comprises: in response to a user control instruction, controlling a smart device to start a personnel position detection mode so as to obtain detection data from a radar module of the smart device; sending the detection data to a display module of the smart device; when the display module receives the detection data, processing the detection data to obtain a personnel motion trajectory; and controlling the display module to display the personnel motion trajectory. In this way, controlling the smart device to start a personnel position detection mode allows for detection data collected by the radar module to be obtained, so as to combine the detection data to determine a personnel motion trajectory, and further controlling the display module to display the personnel motion trajectory allows a user to experience improved smart service, thus satisfying user control requirements for the smart device, and enhancing user satisfaction. The present application further discloses an apparatus for controlling a smart device, and a smart device.

Abstract

A method for controlling an air conditioner (70), comprising: when an air conditioner (70) receives a sleep-aiding instruction, controlling an ultrasonic sleep detection module to perform user sleep detection, so as to obtain state information of a user; according to the state information, determining a sleep-aiding policy of the air conditioner (70); and controlling the air conditioner (70) to execute the sleep-aiding policy. In this way, the state information of a user can be determined by means of the ultrasonic sleep detection module, and then the sleep-aiding policy of the air conditioner (70) is determined on the basis of the state information of the user, such that the sleep-aiding policy determined in this way better fits the change rule of the user state, thereby providing a better sleep-aiding environment for the user when the air conditioner (70) is controlled to execute the sleep-aiding policy, meeting the control requirements of users on the air conditioner (70), and further improving the control accuracy of the air conditioner (70). Also disclosed are an apparatus (50) for controlling an air conditioner (70) and an air conditioner (70).

Abstract

Provided are an air conditioner control method, a control apparatus, an electronic device (500), and a storage medium. The control method comprises: during an air conditioner refrigeration process, obtaining the ambient temperature of an air conditioner indoor unit and the temperature of a refrigerant coil. According to the ambient temperature, obtaining the dew point temperature of the environment where the air conditioner indoor unit is located. And according to the temperature of the refrigerant coil and the dew point temperature, determining whether there is condensation in an indoor unit heat exchanger. The control method provides to an air conditioner a basis for determining whether to perform a condensation removal operation, thereby improving a condensation removal effect.
