医院手术部净化空调系统的节能设计探讨

Discussion about Energy Saving Design on Hospital Operating Department Air-conditioning System

针对当前医院手术部空调系统能耗大的问题,提出较为经济节能的空调系统方式。从空调负荷与调节控制方面,对使用定二次回风风量的二次回风系统与传统的一次回风系统进行比较。结果表明,较一次回风系统,使用定二次回风风量的二次回风系统空调负荷较小,Ⅰ级手术室节省了154.21%,Ⅱ级的节省49.3%,Ⅲ级的节省24.77%,Ⅳ级的节省12.15%。

To reduce the operation costs, a new air-conditioning system was introduced. The comparison of energy consumption and control methods between the Primary Return Air System （PRAS） and Constant Volume Secondary Retum Air System （CVSRAS） was made in this paper. The result shows that the cost can be reduced greatly with the CVSRAS, and energy cost is dropped by 154.21%, 49.3 %, 24.77 % and 12.15 % respectively under the cleanliness class Ⅰ , the class Ⅱ, the class Ⅲ and the class Ⅳ.
