体育场馆改建方舱医院冬季空调采暖系统转换方案研究

Conversion Scheme of Air Conditioning System of Fangcang Shelter Hospital Reconstructed from Gymnasiums in Winter

面对新冠肺炎疫情的突然爆发,我国学者创造性地提出将体育场馆等大型公共建筑迅速改建为大规模收治轻症新冠肺炎确诊患者的“方舱医院”的技术方案,为新冠疫情防治做出了重要贡献。以夏热冬冷地区为例,分析了疫情较常发生的冬季大型体育场馆原有空调采暖方案的缺点,并根据病房区的安全性、热舒适保障性和系统节能性要求,提出了体育场馆改建方舱医院的空调系统更新方案。结合案例,从冷热源设备容量、空调箱送风量和换热能力探讨了新方案的可行性,从气流组织和舒适性两方面对比分析了新方案相对于原方案的优势,并论证了方案实际可用性。该工作对今后“平疫转换”体育场馆暖通空调系统的设计具有一定的参考价值。

Faced with the sudden outbreak of Covid-19,Chinese scholars put forward a novel concept“Fangcang shelter hospital”transformed by large public space including the gymnasiums and cured patients on a large scale,which contributes greatly to the prevention and treatment of Covid-19.Taking hot summer and cold winter area as an example,this paper analyzed defects of the original air conditioning heating systems in“Fangcang shelter hospital”during winter in which the epidemic often occurs,and proposed a new scheme of air conditioning system for“Fangcang shelter hospital”transformed from gymnasiums in terms of safety,energy conservation and comfort.Through case analysis,the feasibility of the new scheme is discussed in terms of the capacity of cold and heat source equipment,air supply volume and heat transfer of air conditioning box.Compared with the original scheme,the advantages of the new scheme are analyzed in terms of air distribution and comfort.The feasibility of the new scheme is demonstrated from the convenience of installation and the added cost of reconstruction.This work has some reference value for the gymnasiums’HVAC design of“transformation of ordinary and epidemic”in the future.
