Problems solved by technology

[0011] First of all, since the first microcomputer 360 and the second microcomputer 280 have to be used as the first microcomputer 360 and the second microcomputer 280, the manufacturing cost of the device is increased.
[0012] Secondly, since the amount of data communication between the first microcomputer 360 and the second microcomputer 280 increases, the reliability of the device for controlling the air conditioner is lowered, and a complex circuit needs to be applied.

Abstract

A device and method for controlling an air conditioner, by using a high-speed microcomputer and a port-expanding microcomputer, the manufacturing cost can be reduced, the reliability can be improved by reducing the data communication volume between the microcomputers, and the application is simple. Circuit configuration. The device is used to control an air conditioner including the following components: a converter for converting an alternating current voltage (ACV) into a direct current voltage (DCV) and boosting the direct current voltage; a smoothing unit for smoothing the direct current voltage from the converter; an inverter for converting the smoothed DC voltage into an AC voltage; and a motor including: an auxiliary microcomputer for controlling a valve for controlling the flow of refrigerant in the air-conditioning duct and a current for controlling the current by receiving a control signal The main microcomputer is used for overall control of the air conditioner including the real-time control unit of the air conditioner and the auxiliary microcomputer.

Description

technical field [0001] The invention relates to a device and method for controlling an air conditioner, in particular to a microcomputer (microcomputer) for controlling an air conditioner. Background technique [0002] The prior art air conditioner generally has two microcomputers to control valves, fans, compressors, power supply units, etc., respectively. [0003] The device for controlling the air conditioner in the prior art will be explained below with reference to FIG. 1 . [0004] Figure 1 shows a prior art device for controlling an air conditioner. [0005] As shown in Fig. 1, the device for controlling the air conditioner in the prior art includes: a converter 200, which is composed of a rectifier unit 210, an active filter 220 and a smoothing capacitor C, and the converter 200 is used to convert commercial AC (AC ) power is converted into direct current (DC); the inverter 300 and the inverter 330 are used to convert the direct current converted by the converter 2...
