摘　　要：空调在现代生活中应用日益广泛。为分析研究空调温度控制器电路的特点,利用LM324运算放大器构成双限比较器、CD4011组成RS触发器、两个47kΩ微调电位器及分压器、负温度系数热敏电阻、电磁式继电器等设计电路,反复调试参数并分析工作原理,再结合Multisim 12.0软件对其仿真测试。结果表明直流12V供电时,电路运行正常,运行指示灯LED1(绿色)和停机指示灯LED2(红色)的点亮、熄灭与负载的运行状态的逻辑关系正确。该电路具有易于实现、节能等特点。With the wide use of air conditioners,it is essential to analyze the characteristics of temperature-controlling circuit of air conditioners,and further test the simulation with LM324 operational amplifier as dual-limit comparator, CD4011 as a trigger, two 47k trimmer potentiometer and divider, a negative temperature coefficient thermistor, electromagnetic relay, parameters repeatedly debugged and the function analyzed,combined with the software Multisim 12. The study shows that the circuit runs smoothly if the DC 12V power supply is given,and the switch of the operation indicator light LED1 （green）and the stop indicator light LED2（red） can respond properly to the running state of the load,which indicates that the circuit has the characteristics of easy realization, energy saving and so on.
