Abstract

The invention discloses a fan control system of an air conditioner and the air conditioner. The system comprises a fan drive, a power accumulator and a DC / DC converter, wherein the fan drive is matched with a fan for driving the fan to operate; the power accumulator is matched with the fan drive for supplying electricity to the fan by power supply voltage when the voltage needed by the fan is the same with the power supply voltage of the power accumulator; or the DC / DC converter is respectively matched with the power accumulator and the fan drive in sequence for converting the power supply voltage to conversion voltage same with the voltage needed by the fan when the voltage needed by the fan is different from the power supply voltage and supplying electricity to the fan by the conversion voltage. The system can overcome such defects as high electromagnetic disturbance, weak reliability and low efficiency in the prior, and achieves the beneficial effects of low electromagnetic disturbance, high reliability and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner fan control system and an air conditioner, in particular to a bus frequency conversion air conditioner fan control system and a bus frequency conversion air conditioner with the system. Background technique [0002] Generally, the driving system of the bus air conditioner fan includes: a driver and a fan. Among them, the wire connecting the driver and the fan is relatively long, and the voltage signal on the wire is a high-frequency switching signal, which causes the entire condenser cavity and evaporator cavity to be covered with such signals (that is, high Frequency voltage signal and large current signal), EMI is poor, and safety is poor. Since the intensity of near-field coupling and far-field radiation is proportional to the magnitude of common-mode current and differential-mode current, the near-field coupling and far-field radiation...
