【中文摘要】 以某型除湿机为对象,以工控机为数据采集和处理平台,搭建了基于焓差法的除湿机性能测试系统。该系统运行稳定可靠,测量精度高,通过传感器采集运行参数,能够快速计算出制冷量、制冷系数COP等性能指标并正确判断运行状态。利用变频器和性能测试系统分别对除湿机进行变频调速控制和动态参数监测,从而研究变频除湿机的除湿性能。实验表明,除湿机在低频运行时具有节能高效的特点。 【英文摘要】 This paper constructed a performance test system of dehumidifier based on method of enthalpy difference which runs stably and accurately,it collected data by sensors in order to acquire performance index such as refrigerating capacity or COP(coefficient of performance) and judge the performance of device.In order to study dehumidify performance of variable frequency dehumidifier,transducer and performance test system were used to make dehumidifier work at different frequency and monitor dynamic parameter.The experiment express that dehumidifier have characteristics of energy-saving and high-level efficiency when it work at low frequency. 【中文关键词】 控制系统; 变频; 除湿机; COP; 节能 【英文关键词】 frequency conversion; dehumidifier; COP; energy saving
