摘　　要：基于焓差法的双工况人工气候室主要由环境室、空气处理系统、风量测量系统以及计算机测控系统组成,该实验平台能对风量、温度、湿度等热工性能参数做到高精度测定(风量±2%,温度±0.5℃,湿度±0.5%,压力±1 Pa),在该实验平台研究了环境温度以及迎面风速对热管换热器换热性能的影响。实验结果表明,该实验平台可以承担对换热器的检测任务,达到了设计目的。The dual-condition artificial climate chamber based on the enthalpy difference method is mainly composed of an environmental chamber,an air handling system,an air volume measurement system and a computer measurement and control system.The experimental platform can measure air volume,temperature,humidity and other thermal performance parameters with high precision(air volume±2%,temperature±0.5℃,humidity±0.5%,pressure±1 Pa).The effects of ambient temperature and oncoming wind speed on the heat transfer performance of the heat pipe heat exchanger were studied on this experimental platform.The experimental results show that the experimental platform can undertake the detection task of the heat exchanger and achieve the design purpose.
