摘要:
为解决常规高精密环控系统温度波动大的问题,提出了1种高精度温度控制的半导体制冷系统。该系统基于半导体制冷技术,并结合直流变频压缩机恒温冷水机组。以专家比例-积分-微分(PID)控制方法和制冷量与电加热量双向趋近调节方式进行控制。试制了实验样机,对该系统的制冷性能、供水温度控制精度及系统抗干扰性能进行了实验研究。研究结果表明,系统供水温度波动范围为±0.01 ℃; 开机启动至供水温稳定仅需16 min; 2 kW负载瞬间冲击的响应时间为2 min,冲击结束后95%时间内系统供水温度的波动幅度仅为±0.005 ℃,且未发生超限和震荡现象。
Abstract:
A semiconductor refrigeration system with high precision temperature control is proposed to solve the problem of large temperature fluctuation of high precision environment control systems. This system is based on semiconductor refrigeration technology and combined with a constant temperature chiller using direct-current inverter compressors. The expert proportion-integral-differential(PID)control method and bidirectional approach regulation of refrigeration capacity and electric heating capacity are used for system control. The experimental prototype is produced,and the refrigeration performance,water supply temperature control accuracy and anti-interference performance of this system are experimentally studied. The results show that,the fluctuation range of water supply temperature is within ±0.01 ℃; it takes only 16 minutes from start to stabilize the water supply temperature; the response time of 2 kW load instantaneous impact is 2 minutes,and the fluctuation range of water supply temperature is only ±0.005 ℃ in 95% of the time after the impact,and there is no over-limit and oscillation.
