Improvement and discussion on HVAC system design for a hospital in Fujian
摘要：
简述了福建省某医院的项目概况与空调设计参数。介绍了该医院空调系统冷热源的配置、空调与通风系统。提出了空调冷水系统大温差及风机盘管、空调箱选取不同冷水温差，一些诊室采用加大换气次数的非净化型风机盘管加新风方案。分析了采用一个开式膨胀水箱定压多个空调水系统方案的可行性。
Abstract：
Presents the general situation and air conditioning design parameters of a hospital project in Fujian Province. Elaborates the cold and heat source configuration, air conditioning and ventilation systems of the hospital. Puts forward the schemes of large temperature difference air conditioning chilled water system, different chilled water temperature differences for fan coil units and air handling units and unpurified fan coil units with outdoor air for some consulting rooms to increase the air change rate. Analyses the feasibility of using an open expansion tank to fix the pressure of multiple air conditioning water systems.
