Description

变频空调的控制方法、装置及变频空调Control method and device of inverter air conditioner and inverter air conditioner

技术领域technical field

本发明涉及温控技术领域,特别涉及一种变频空调的控制方法、装置及变频空调。The invention relates to the technical field of temperature control, in particular to a control method and device for an inverter air conditioner and an inverter air conditioner.

背景技术Background technique

通信机柜或者机房采用的空调一般为变频空调。变频空调系统复杂,电控部分主要分为主控单元(负责各种传感器信息采集、高低压开关状态检测、变频制冷逻辑设计)和驱动单元(负责驱动和监控压缩机运行)。较复杂一些的变频空调系统,主控单元和驱动单元是完全独立的,它们之间通过RS485硬件接口进行信息交互。主控单元通过采集变频空调内部各个温度关键点的温度和高低压开关的状态信息,确定压缩机运行频率和步进频率,并通过通讯方式发送给驱动单元。驱动单元接收到信息后,执行进一步操作。但是当主控单元和驱动单元之间通讯出现故障时,驱动单元无法从主控单元接收到压缩机驱动信息和系统安全信息,此时现有技术通常是通过驱动单元控制压缩机立即停机,以使得空调停止工作,然而这样会造成机柜或者机房的温度很快升高,进而导致机柜或者机房的通信设备出现故障。The air conditioners used in communication cabinets or computer rooms are generally inverter air conditioners. The inverter air conditioner system is complex, and the electronic control part is mainly divided into the main control unit (responsible for various sensor information collection, high and low voltage switch status detection, frequency conversion refrigeration logic design) and the drive unit (responsible for driving and monitoring the operation of the compressor). For more complex frequency conversion air conditioning systems, the main control unit and drive unit are completely independent, and information exchange is carried out between them through the RS485 hardware interface. The main control unit determines the operating frequency and step frequency of the compressor by collecting the temperature of each key temperature point inside the inverter air conditioner and the state information of the high and low voltage switches, and sends them to the drive unit through communication. After the drive unit receives the information, it performs further operations. However, when the communication between the main control unit and the drive unit fails, the drive unit cannot receive compressor driving information and system safety information from the main control unit. At this time, the prior art usually controls the compressor to stop immediately by the drive unit, so as to Make the air conditioner stop working, but this will cause the temperature of the cabinet or the computer room to rise quickly, and then cause the communication equipment in the cabinet or the computer room to malfunction.
