大型综合气候实验室基础环境模拟系统设计

目的设计出一套适用于大型综合气候实验室的基础环境模拟系统,用于实现温度和湿度等基础环境。方法通过分析实验室功能和热负荷,并综合考虑国外气候实验室的设计特点,提出基础环境模拟系统总体方案,该系统由复叠制冷系统、载冷载热系统、循环风系统、新风系统等8个子系统组成,并完成分系统设计。结果调试结果表明,基础环境模拟系统可实现-55~74℃的温度环境及RH为5%~95%的湿度环境,并可完全支持降雪、太阳辐射、冻雨、淋雨、吹风等特殊气候试验。结论设计出的基础环境模拟系统满足大型综合气候实验室的使用要求。

Design of Primary Climatic Environment Simulation System for Large Comprehensive Climatic Environment Test Laboratory

The paper aims to design a primary climatic environment simulation system for large comprehensive climatic en- vironment test laboratory to create temperature and humidity conditions. Based on the analysis of function and heating capacity of the laboratory and design characteristics of similar climatic environment test chambers at home and abroad, a primary cli- matic environment simulation system including cascade cooling subsystem, secondary refrigerant and heating subsystem, recir- culating air subsystem, fresh air subsystem, etc. was designed. The test results showed that, this primary environment climatic simulation system can control the temperature and humidity of the laboratory at 55 to 74 ℃ and 5%RH to 95%RH and can support special climatic tests including snow, solar radiation, sleet, rain, wind, etc. The primary climatic environment simulation system designed can meet the using requirements of large comprehensive climatic environment test laboratory.
