空调系统电气控制单元设计与仿真

空调设备是夏季防暑、冬季防寒的重要设备,对北方和南方的居住环境适宜度调节都具有非常重要的作用。常规控制方法作用之下,空调系统存在响应速度慢,系统满载运行功率高、能源浪费等突出问题。该文针对空调设备的电气控制进行系统研究,并开展相应的实验验证。首先对空调系统的组成结构和工作原理进行分析,给出基于STM32嵌入式电气控制系统的硬件结构和软件设计方案,并给出空调制冷过程、冷却过程、蒸发器工作过程对应的算法模型。实验以5组空调设备为实验对象,以常规控制方法为参照方法,证实在该方法控制作用下,空调设备可以实现快速的功率效应,并且具有较低的满载运行功率,从而达到有效的节能效果。实验结果充分证明该文设计的空调系统电气控制硬件和软件的有效性。

Air conditioning equipment is an important device for preventing heatstroke in summer and cold in winter,and plays a very important role in adjusting the suitability of living environments in both the north and south.However,under the influence of conventional control methods,the air conditioning system has prominent problems such as slow response speed,high operating power at full load,and energy waste.In this article,a systematic study is conducted on the electrical control of air conditioning equipment,and corresponding experimental verification is carried out.Firstly,the composition structure and working principle of the air conditioning system were analyzed,and then a hardware structure and software design scheme based on the STM32 embedded electrical control system was proposed.Algorithm models corresponding to the refrigeration process,cooling process,and evaporator working process of the air conditioning system were also provided.During the experiment,five sets of air conditioning equipment were used as experimental objects,and conventional control methods were used as reference methods.It was confirmed that under the control of the method proposed in this paper,the air conditioning equipment can achieve fast power effects and have lower full load operating power,thereby achieving effective energy-saving effects.The experimental results demonstrate the effectiveness of the electrical control hardware and software of the air conditioning system designed in this paper.
