双限温度控制器的设计与EWB仿真

Design of Double-valve Temperature Controller and EWB Simulation

介绍一种采用集成温度传感器AD590设计的双限温度控制器,温度超过上限,启动制冷;温度低于下限,启动加热。温度超出设定的范围,启动报警。EWB仿真结果表明该电路达到了设计要求,具有一定的实用价值。

This paper introduces a double-valve temperature controller using IC temperature sensor （AD590）. When temperature exceeds upper limit, refrigeration circuit starts. When temperatare is less than lower limit, calefaction circuit starts. An alarm is given as the temperature goes beyond the set valves. EWB simulation result shows that this circuit meets the design requirements and has some application value.
