摘要:

 以重庆地区手术部的净化空调系统为研究对象,利用焓湿图绘制全年室外空气状态参数的散点分布图,分析了重庆地区的气候特征。为了分析空调方案的经济性,基于空调系统的全年能耗,以单位面积年度耗电量作为经济性评价指标,详细阐述了Ⅰ级手术室单位面积年度耗电量的计算过程,分析了室内设计温度和湿度对空调能耗的影响。结果表明,相对湿度对能耗的影响远大于温度,因此在重庆地区,在满足规范和卫生要求的前提下,提高室内相对湿度的设计值有明显的节能效果。

Abstract:

Takes the purification air conditioning system of the operation department in Chongqing as the research object. Use the psychrometric chart to draw the scatter point distribution diagram of outdoor air state parameters throughout the year, which is used to analyse the climatic characteristics of Chongqing area. In order to analyse the economics of the air conditioning scheme, based on the annual energy consumption of the air conditioning system, uses the annual power consumption per unit area as the economic evaluation index, and elaborates the calculation process of the annual power consumption per unit area of the first-level operating room. Analyses the influence of indoor design temperature and humidity on the energy consumption of air conditioning, and finds that the influence of relative humidity on energy consumption is much greater than that of temperature. Therefore, in Chongqing area, under the premise of meeting specifications and sanitary requirements, increasing the design value of indoor relative humidity is an effective energy saving measure.
