极深地下实验室空调和新风系统设计方法研究

Research on design methods of air conditioning and outdoor air systems in an extremely deep underground laboratory

极深地下实验室项目属于国家重大科技基础设施项目,环境特殊、空间狭小、温湿度及洁净度控制要求高,对空调系统和新风系统设计提出了较大挑战。本文提出了以地下天然水资源作为空调冷源,新风降氡及吸附除氡相结合的方式来实现实验装置对环境的低氡要求,无需新风及排风的转轮除湿机,空调机组非标定制等多种措施,有效地解决了极深地下实验室空调系统和新风系统的各种设计难题。

The extremely deep underground laboratory project is a major national science and technology infrastructure project,with special environment,small space,high temperature and humidity,and high cleanliness control requirements,which proposes great challenges to the design of air conditioning and outdoor air systems.This paper proposes some measures including taking underground natural water source as air conditioning cold source,the combination of outdoor air radon reduction and adsorption radon removal to achieve the low radon requirements of the experimental device for the environment,rotary dehumidifier without outdoor air and exhaust air,non-standard customization of air conditioning unit,which effectively solves various design problems of the air conditioning system and outdoor air system in the extremely deep underground laboratory.
