国家会展中心改建临时隔离收治点通风系统设计
Design of ventilation systems for temporary isolation and treatment points reconstructed from National Convention and Exhibition Center
摘要：
介绍了国家会展中心改建为临时隔离收治点的建筑总体平面布局及流线。对患者收治区通风系统方案的确定进行了分析，包括基于原有空调系统、排烟系统改造的可行性，最终确定了新增机械排风系统的方案，并详细介绍了该通风系统的技术措施。最后，总结了本次应急改造项目的可提升之处，并对大型会展建筑应对突发疫情的平疫结合暖通设计作了展望，供会展类大空间建筑空调通风平疫结合设计参考。
Abstract：
This paper presents the general building layout and streamline of the temporary isolation and treatment point reconstructed from the National Convention and Exhibition Center. The determination of the ventilation system scheme in the patient admission area is analysed, including the feasibility of reconstruction based on the original air conditioning system and smoke exhaust system. The scheme of adding a mechanical exhaust system is determined, and the technical measures of the ventilation system are presented in detail. Finally, the improvement of this emergency project is summarized, and the HVAC design of a combination of peacetime and epidemic for large-scale exhibition buildings to deal with the sudden epidemic situations is looked forward to, which can be used as a reference for the design of a combination of peacetime and epidemic of air conditioning and ventilation for large space buildings like the exhibition.
