摘　　要：为了测试机柜温控设备性能以及优化设计,按照欧洲标准EN-14511,研制了一套机柜温控设备测试室。测试室可以提供-45℃～70℃的温度和30%～90%相对湿度的环境。控制系统选用研华BAS-3000系列DDC直接数字控制器。恒温恒湿工况采用露点温度控制的方法,温湿度控制精度能分别达到±0.2℃,±1%的要求.经过实际应用,该系统稳定、可靠.Performance testing chamber is designed to test the performance of temperature control device and optimal design is carried out in accordance with european standards EN-14511. The test chamber can provide the environment of -45℃- 70℃ temperature and 30% - 90% relative humidity. The Advantech BAS-3000 Series DDC Direct Digital Controller is used to control the system. Through the control of dew point temperature in the conditions of constant temperature and humidity, it can achieve the required pre- cision ＋ 0.2℃, ＋ 1%. The system is stable and reliable during the practical application.
